With the rapid development of China's construction industry, more and more building materials are applied to the construction of construction projects. The following is what I collected for you. Welcome to read the reference!

Analysis on the Recovery and Application of Waste Polymer Materials in Building Materials

1. Status of recycling of waste polymer materials in China

The treatment of waste polymer materials can be described as a double-edged sword, which can save resources and protect the environment if used well. If it is not handled well, it will bring some negative effects to our production and life, and even appear toxic and harmful phenomena. Applying waste materials to building construction can not only further reduce the impact of polymer materials on our production and life, but also provide more and better sources of building materials for building projects. With the development of science and technology and social progress, more and more new polymer materials will come out, thus improving the economic benefits of the whole construction industry and realizing the organic unity of environmental benefits, social benefits and environmental benefits. The technology of treating waste polymer materials in China is still relatively backward, and most of the treatment methods are only simple regeneration and compound regeneration.

In this case, a large number of waste polymer materials will be discarded as garbage at will. A large number of waste polymer materials have brought great influence to our daily life and seriously polluted our environment. For example, the plastic film scattered in the soil is easy to cause soil hardening, which is not conducive to the absorption of oxygen, air, moisture and light by crops; Film fragments scattered on the ground are also easy to cause fires in related buildings; In the process of biodegradation, some waste polymer materials will release toxins that are very harmful to human health. At this stage, we urgently need to deal with these waste plastics, fibers, rubber and other issues.

2. Application of waste polymer materials in building materials

Today's world is a world full of polymer materials. While enjoying the great convenience brought by polymer materials to our production and life, we should also consider the disposal of waste polymers. There are advantages and disadvantages in treating waste polymer materials. If the waste is treated well, it will help to reduce the harm caused by polymer materials, and not only that, it will also help us reduce the production and living costs. If it is not handled properly, it will harm the environment and our health. Using waste polymer materials as building materials can effectively solve the problem that waste materials cannot be treated, on the one hand, it can reduce the harm of waste polymer materials, on the other hand, it provides a new building source for engineering construction. With the further development of science and technology, new materials will emerge one after another, and finally realize the unity of economic, environmental and social benefits. First of all, waste polymer materials can be used as building wall materials. With the further announcement of banning the use of clay bricks in China, China's construction industry began to further strengthen the development and application of new wall materials. Therefore, recycling waste polymer materials is of great significance, which greatly supports the further innovation of wall materials.

At this stage, the related technologies of new wall materials have become increasingly mature and gradually applied to production practice, which is closely related to our production and life. Specifically, it mainly includes the following aspects: First, the sample brick is made of plastic and glass. At present, China has developed a kind of sample brick made of glass and plastic, which has been widely used. The second is metal rubber concrete. Metal rubber concrete material has high efficiency, which is beneficial to solve various structural problems of concrete, such as poor sound insulation effect and insufficient seismic efficiency. Thirdly, using polystyrene foam to produce concrete thermal insulation blocks. This kind of block is usually small in scale, has strong sound insulation effect and high compressive strength, and belongs to high-quality lightweight wall materials. In the actual working process, the cement slurry layer wrapped around the block polystyrene foam plays an important role in the skeleton, so the foam is basically unaffected by external forces. Fourthly, building tiles made of fly ash and waste plastics. On the one hand, the development of this kind of tile can greatly reduce the cost, on the other hand, it can eliminate white pollution. Fifth, making full use of waste foam materials to make new insulation bricks has the characteristics of good fire prevention effect and low cost.

Secondly, the application of waste polymer materials in building decoration materials. Every kind of building materials cannot be short of building materials. If the building lacks decorative materials, it will greatly affect our daily production and life, even people's health, and even cause major diseases. Therefore, we can apply waste polymer materials to building decoration materials. On the one hand, it can reduce the construction cost of the whole building, on the other hand, it can also improve safety efficiency and reduce environmental pollution, which can be described as killing two birds with one stone.

Specifically, you can operate from the following aspects:

First, make full use of waste plastics to produce building decorative boards. At this stage, the relevant departments of our country have carried out research in this field and achieved certain results. The main principle of this technology is to use raw materials such as pigment additives, waste plastics and reinforcing agents. As a basic unit, waste plastics are cleaned, dried and melted into fine particles, and at the same time, reinforcing agents and pigment additives are added and cooled into the shape we need. On this basis, they are painted with bright colors and made into finished products.

Secondly, waste polymer materials are used to make a waste material for tissue combustion. According to related reports, by adding some additives to some waste plastics and sawdust, an effective building decoration material can be made to prevent combustion. Experiments show that this material has strong flame retardancy and can be completely applied to buildings. On the one hand, it can provide more kinds of decorative building materials, on the other hand, it can protect the environment and make contributions to beautifying the environment. Third, the application of waste polymer materials in other building materials. In recent years, waste polymer materials have been gradually applied to building materials and have been widely used.

Specifically, it includes the following aspects: First, waterproof materials made of waste polystyrene foam and fly ash. Using ordinary silicone rubber as material and adding a small amount of preservatives, a good quality thermal insulation and waterproof material can be formed, which can organically combine waterproof and thermal insulation. The thermal insulation waterproof material has high strength, relatively low density and excellent thermal insulation effect, which can be said to be a very ideal roof thermal insulation material. Second, use waste hydrocarbon resin to produce plastic floor. At present, our country has developed this product and achieved great success. In the plastic family of the world, the output of "PVC" is relatively high, and the products are relatively more than the waste products.

Because "PVC" is a halogen-containing substance, the recovery of this substance is limited by many factors. Many building materials can be produced by using this technology. Our common useful waste agricultural film, calcium carbonate, lubricant, stabilizer and color paste can be made into plastic floor through a series of processes such as mixing and banburying. In a word, the application of waste polymer materials in construction, on the one hand, reduces the construction cost, on the other hand, protects the environment, which can be said to be multi-purpose. In recent years, China's research in this field has also achieved certain results and achieved great success.

3. Conclusion

With the development of society, the application range of waste polymer materials is getting wider and wider, and it has become the general trend to apply these waste materials to buildings. To this end, we should attach great importance to it. In daily life and work, to further strengthen the research of this work, relevant departments should further increase capital investment, organize scientific research personnel to conduct research, and strive to build a resource-saving and environment-friendly society.
