A brief analysis of the application of recycled plastics in building materials
With the continuous improvement of the comprehensive utilization technology of waste plastics, the new materials have been widely used in recent years. Recycled plastic is formed after the waste plastic is processed and crushed. It has a certain elasticity, high strength and wear-resisting property and good insulation performance, so it has been used more and more in the construction industry. Linyi plastic bucket factory below to explain to everyone. The application of recycled plastic is mainly used to make the building materials of various thermal insulation types. Yu lian ying was studied with flame retardant thermoplastic plastic waste and sawdust powder production process and performance of building decoration materials, the material of the flame retardant performance meet the national standard (GB5464-1985) of the building materials noncombustible materials specified in the request. The research results of the application of the road in China and abroad show that the application of recycled plastic is feasible in road engineering and has been applied in practical engineering. Russian researchers will foam in road construction, as a new road insulating material, is used to replace traditional antifreezing layer, in order to ensure embankment does not produce frozen ice crystal precipitation, the flow and the layered, and play the role of prevention of road frost heave and frost boil. In concrete, the application of the regenerated plastic into particles with different particle size is directly added into the concrete material to be made into a new type of concrete called recycled plastic concrete. At present, the application of a recycled plastic into concrete is still in the stage of laboratory research, the research of recycled plastic modified concrete does not see more, there is no domestic study of recycled plastic modified concrete. From the point of literature has been published abroad, mainly will be recycled plastic particles all or partly replace replace the aggregate in concrete, and conducted a series of recycled plastic modification of the physical, chemical and mechanical properties of concrete is studied. Will be recycled plastic used in the building materials can meet the corresponding standards, and can obtain excellent mechanical and physical properties, so the application in building engineering will be more and more widely, the development of recycled plastic modified materials has a very broad prospects. The research and prospect of regenerated plastic modified concrete from abroad can be found in the study of modified concrete from abroad, and it can be found that recycled plastics are used to modify concrete. Plastic waste recycling, classification, after washing, crushing into granular or powder mixed with concrete, recycled plastic formed by modified concrete while decrease in physical and mechanical performance, but able to restrain the emergence and development of internal cracks, concrete show better ductility. The plastics are insoluble in water, and are more difficult to dissolve in chemical solvents.
