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 a high-resilience polyurethane plastic track. The polyurethane plastic track is characterized in that the polyurethane plastic track is prepared from the following raw materials: paraformaldehyde, dimethylethanolamine, toluene, rosin, phenol, hydrogen peroxide, a formic acid, a phosphoric acid, methyl methanesulfonate, attapulgite, a hydrochloric acid, dimethylbenzene, gamma-aminopropyltriethoxysilane, hydroxyethyl methylacrylate, di(2-ethyl-hexyl)phthalate, 2,4-dihydroxybenzophenone, 2-chloromethyl benzimidazole, polypropylene glycol, diphenylmethane diisocyanate, a NaOH solution with the concentration of 8-10% and de-ionized water. The prepared polyurethane plastic track has the high performance of high resilience, wear resistance, slip resistance, attractive color, clean site, easiness for maintenance and management, and no influence of a climatic condition and the like.

Description

technical field [0001] The invention relates to the technical field of plastic preparation, in particular to a polyurethane plastic runway with good resilience 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 polyurethan...
