Problems solved by technology

[0004] The traditional polyurethane floor covering products are all toluene diisocyanate (TDI) type. Due to the heavy metal substances contained in the TDI polyurethane track, it will oxidize and pollute the environment during use.
In addition, the TDI polyurethane component also contains a variety of catalysts (including lead, mercury, tin), diamine chain extenders, organic molecular plasticizers, solvents, rubber compounding agents and bisphenyl solvents and other toxic and harmful chemicals. Adverse effects on the human body and the environment

Abstract

The invention discloses an ultravioresistant polyurethane plastic racetrack, which is characterized in that the plastic racetrack is prepared from the following raw materials: paraformaldehyde, dimethylethanolamine, methylbenzene, colophony, phenol, hydrogen peroxide, formic acid, phosphoric acid, trimethylolpropane, gamma-glycidoxypropyltrimethoxysilane, nano cerium oxide, acetone, bisphenol A glycerol dimethacrylate, methanol, propylene glycol monomethyl ether, dioctyl phthalate, tetra[beta-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]pentaerythritol ester, 2,2'-dihydroxy-4-methoxybenzophenone, polypropylene glycol, diphenylmethane diiso-cyanate, 8-10% of NaOH solution and deionized water. The polyurethane plastic racetrack prepared according to the invention has excellent properties of good elasticity, wear resistance, skid resistance, attractive color, clean site and easiness for maintenance and management, and is not influenced by weather and like conditions.

Description

technical field [0001] The invention relates to the technical field of plastic preparation, in particular to an ultraviolet-resistant polyurethane plastic runway and a preparation method thereof. [0002] technical background [0003] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. Polyurethane has excellent properties such as excellent wear resistance, high strength, high elongation, high elasticity, oil resistance, and radiation resistance. Polyurethane used in flooring materials has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It also has certain elasticity and color, and has certain UV resistance and aging resistance. [0004] The traditional polyurethane flooring materials are all toluene diisocyanate (TDI) type. Due to the heavy metal substances contained in the TDI polyureth...
