Manufacturing process of silicon PU plastic track

Abstract

The invention discloses a manufacturing process of a silicon PU plastic track. The silicon PU plastic track is prepared from the following raw materials in parts by weight: 30 to 34 parts of blocked isocyanate, 25 to 28 parts of polysiloxane, 5 to 8 parts of polyether main ingredient, 31 to 35 parts of polyether auxiliary ingredient, 10 to 14 parts of rosin water, 11 to 15 parts of polyhydric alcohol benzoate, 12 to 17 parts of hydroxyl-terminated polybutadiene, 34 to 37 parts of polyurethane resin, 4 to 7 parts of talcum powder, 14 to 17 parts of kaolin, 6 to 9 parts of lead salt, 10 to 15 parts of organic tin, 20 to 24 parts of phthalocyanine blue, 16 to 19 parts of red clay, 11 to 16 parts of stearate, 4 to 9 parts of phthalate, 20 to 27 parts of black rubber particles and 13 to 16 parts of sulphur, wherein the polyether main ingredient is polyether polyol with high molecular weight of 5000 to 6000, and the polyether auxiliary ingredient is polyether polyol with low molecular weight of 2000 to 3000. The manufacturing process has the advantages of good high and low temperature resistance, weather resistance, oxidation resistance and air permeability, strong adhesion and impact adsorption capacity, excellent stability, attractive appearance, simplicity in manufacturing and strong mechanical performance.
