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 provides waterproof and leakageproof modified polystyrene composite virgin rubber and a preparation method of virgin rubber and rubber mud. Raw materials in a product contain various chemical components which are mild in property and are free of toxic components of benzenes, ketones, formaldehyde and the like. The product is colloidal, strong in mobility and permeability. Although the product belongs to chemical engineering, the product is high in safety coefficient, non-toxic in contact for non-edible purpose, nonflammable, non-radioactive, non-volatile and stable in performance of colloid, has the characteristics of waterproofness, antioxidation, corrosion resistance, electric insulation and the like, can be powerfully adhered to the surfaces of substrates such as cement and ironwood and can be further mixed and mutually coagulated with wet cement. When virgin rubber is used, water or gasoline can be added to dilute. The virgin rubber can be stored for over 10 years without deterioration, is harmless to ecological environment and thus is a modern environment-friendly building protective 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 ...
