Problems solved by technology

On the other hand, in terms of chemical properties, polystyrene has excellent water resistance, oxidation resistance, corrosion resistance, etc., and has excellent moisture resistance and impermeability performance. However, polystyrene itself is not easy to bond to other materials and has a large thermal expansion coefficient. Features, easy to be finished alone or copolymerized with other chemical components, but cannot be directly and simply applied to construction and other projects

Abstract

The invention relates to a method for preparing modified polystyrene composite raw rubber, raw rubber and cement for waterproofing and leakage prevention. The various chemical components contained in the raw materials of the product of the present invention are mild in nature, free of benzene, ketone, formaldehyde and other toxic components. The finished product is colloidal, with strong fluidity and permeability. Although it belongs to the chemical industry, it has a high safety factor. Non-edible contact is non-toxic, non-flammable, non-radioactive, and non-volatile. The colloid has stable performance, waterproof and anti-oxidation. , anti-corrosion, electrical insulation and other characteristics, can be strongly bonded to the surface of cement, iron wood and other substrates, and can also be mixed with wet cement to coagulate. When raw rubber is used, it can be diluted with water or gasoline. It should be stored for a long time for more than ten years without deterioration. It is harmless to the ecological environment and is a modern and environmentally friendly building protection material.

Description

technical field [0001] The invention relates to the technical field of resource reuse, in particular to a modified polystyrene composite raw rubber used for waterproofing and leakage prevention, and a preparation method of the raw rubber and cement. Background technique [0002] As we all know, polystyrene, as a cheap, waterproof and easy-to-form thermoplastic resin, has a strong market demand and various types of products, but because it is not easy to recycle and regenerate, and it is difficult to degrade in the natural environment, it causes the so-called "white pollution" and so on. Environmental issues. The difficulty of reusing polystyrene products is mainly due to their low mass (especially expanded types), low residual value, and the lack of a market for post-recycling. If we can recycle and densify polystyrene foamed products and make them have new uses and explore new markets through technological innovation, environmental problems such as white pollution will be ...
