Embodiment 2

[0027] Example 2: Using aqueous solution to process polyurethane elastomer to make a spray-coated non-threshing plastic sports track

[0028] Make the plastic primer layer by the method of above-mentioned embodiment 1, after the primer layer is cured, take by weighing 100 kilograms of the above-mentioned aqueous solution processing polyurethane elastomer adhesive, add the EPDM rubber particle of 4 millimeters of particle diameters of 40 kilograms, After uniform mixing, pour it into the plastic spraying machine, and evenly spray it on the primer layer to form a plastic anti-skid surface layer with a thickness of 4 mm. According to this process, spray the whole primer evenly, and wait for the glue to solidify. Finally, draw the line as required to make a spray-coated non-threshing plastic sports track.

Abstract

The making process of plastic track includes the following steps: reaction between dihydroxy polyether polyol and/or trihydroxy polyether polyol and toluene diisolcyanate to produce component A; preparing component B with 3, 3-dichloro-4, 4-amino diphenyl methane and/or 4, 4-methylene-bisdiethyl diphenyl, bis-6-methyl diphenylamine, tetrahydroxyamino polyether polyol, stuffing, plasticizer, nanometer base material, etc.; mixing component A, component B, catalyst and water solution to form the water solution processed polyurethane elastomer adhesive; and mixing the water solution processed polyurethane elastomer adhesive, waste tyre grain or other rubber grain and stuffing to form mixture for the plastic track. The plastic track has low cost.

Description

technical field [0001] The invention relates to a manufacturing method of a plastic sports field and a track, in particular to a method for manufacturing a plastic track by using an aqueous solution to treat a polyurethane elastomer. Background technique [0002] The international standard plastic sports ground runway, one, adopts polyurethane material as the main body, and its shortcoming is that the above-mentioned materials are slightly toxic; the other, adopts rubber material, and its shortcoming is that it is expensive. The advanced method of making plastic sports ground runway, such as Chinese patent application number is 01114616.8, title is called: " the method for making plastic sports ground and runway by adopting nanometer material modified polyurethane " disclosed content, its shortcoming is that the product cost of manufacture is high High, various technical indicators, such as tensile strength, oxidation resistance, weather resistance, color...
