Abstract

The invention discloses an environmental-friendly type polyurethane non particle spraying material used in stadium ground layer, which is formed by the mixing of component A and component B; wherein, the weight proportion of component A and component B is 1:3; the component A is obtained by mixing diphenylmethane diisocyanate and polyether glycol according to certain proportion; the component B is obtained by mixing polyether-tribasic alcohol, polyether glycol, dry process montmorillonite clay, 3, 5-methyl-sulfide base tolylene diamine, trimethylolpropane, epoxy resin, two-octyl, silica dioxide powder, calcium bicarbonate, organobentonite, iron oxide red or tartrazine-phthalo green mixture and metal carbonyl carboxylate according to certain proportion. The invention also discloses a preparation method of the material, which includes the steps: first preparing the component A and the component B respectively in specific condition, and mixing and stirring the component A and the component B to obtain the material of the invention. As the material of the invention contains no TDI and MOCA, the polyurethane non particle spraying material has no toxicity and safety hidden danger, and is an environmental-friendly material.

Description

technical field [0001] The present invention relates to a kind of macromolecule material—spraying pavement material for stadium ground layer, in particular to an environment-friendly polyurethane stadium ground layer particle-free spraying material prepared by nano-montmorillonite / environmental protection polyurethane plastic and its preparation method, which belongs to stadium The field of production of sprayed pavement materials for the ground floor. Background technique [0002] The polyurethane elastomer of the non-slip surface layer material of the track and field race track pavement of modern stadium, known method is: earlier make polyurethane prepolymer (hereinafter referred to as A Components); and then the A component and the chain extender-cross-chain agent polyether polyol\diol butanediol, dibasic ammonia (ie MOCA, 3,3'-dichloro-4,4'-di Aminodiphenylmethane) and filler (commonly known as component B) are mixed, and then the polyurethane elastomer made by catalyst...
