Abstract

The invention discloses an environment-friendly polyurethane composite material for a roller outer ring. The environment-friendly polyurethane composite material comprises the following raw materials in parts by weight: 80-95 parts of a thermoplastic polyurethane elastomer, 0.5-0.8 part of fatty alcohol-polyoxyethylene ether, 11-13 parts of allyl alcohol, 0.7-1 part of methyl triethoxysilane, 10-16 parts of montmorillonite powder, 1-4 parts of butyltin trioctoate, 0.7-1 part of diacetone acrylamide, 1.2-1.7 parts of calcium ricinoleate, 0.7-0.9 part of 1,2-dimethylimidazole, 1-2 parts of casein, 1-1.5 parts of ammonium metaborate, 0.6-2 parts of alkylolamide, 7-9 parts of superfine silicon dioxide aerogel, 1-3 parts of isocyanate, 2-5 parts of tertiary amine, 3.5-4 parts of methyl isocyanate cyclohexane and 2.3-2.7 parts of high-solid low-adhesion alkyd resin. The environment-friendly polyurethane composite material is good in safety and environmental friendliness and low in processing cost in the production process; and modified mountain flour is mixed with silicon oxide aerogel and is processed by virtue of silane, so as to obtain a modified filler with good surface dispersity; and the filler can be well dispersed in polyurethane, so that the strength and stability of the finished product are improved.
