Problems solved by technology

Halogen flame retardants are not only compatible with polymer materials, but also easy to use. However, research by relevant institutions has shown that when halogen-containing flame retardant materials are discarded and burned, they will generate a large amount of smoke, produce highly toxic gases, and cause cancer. This is also the reason why the European Union issued a ban to force halogenated flame retardants to withdraw from the market
[0004] Chinese patent CN102964562 A discloses a polyurethane elastomer composite material used for laying the ground of warships and its preparation method. agent, thickener, pigment, defoamer and bactericidal antifungal agent, component B is composed of flame retardant polymer polyol, isocyanate and plasticizer, this invention solves the problem of flame retardant effect caused by easy migration of flame retardant It cannot be a permanent problem, but the flame retardant used in this invention is a flame retardant tetrabromophthalic anhydride diol ester. The flame retardant contains halogen. When it is burned on fire, it emits a large amount of smoke and releases highly toxic gases. The plasticizer uses Dioctyl phthalate, a scientific study found that phthalate plasticizers are reproductive and developmental toxic, and even carcinogenic

Description

technical field [0001] The invention belongs to the technical field of polyurethane products, and in particular relates to an environment-friendly halogen-free high-performance polyurethane floor material and a preparation method thereof. Background technique [0002] Common ground materials can be divided into: concrete, ceramic tile, wooden floor, epoxy floor, polyurethane floor, etc. Concrete floors are mostly used for ordinary outdoor road floors. Wooden floor floors and ceramic tile floors are not suitable for industrial floors and are more suitable for homes. The epoxy floor is easy to clean as a whole, waterproof, mildew-proof, highly wear-resistant, and resistant to a certain degree of chemical corrosion. However, epoxy materials are brittle, have poor elasticity, poor weather resistance, and poor UV resistance, so they cannot be used outdoors for a long time, and the economy is poor. [0003] Polyurethane floor raw materials are environmentally friendly and pollut...
