Problems solved by technology

[0003] China Patent Network has proposed a TPR material for shoe sole raw materials and its preparation method (publication number is CN111333992A). However, because TPR generally has very little polarity, it has no good affinity with neoprene and polyurethane adhesives with strong polarity, which brings difficulties to the adhesion of TPR and affects the later stage. Glue bonding adds to the difficulty

Abstract

The invention belongs to the technical field of TPR preparation, and particularly discloses an improved TPR preparation method. According to the invention, the TPR is prepared from the following raw materials in parts by weight: 85-115 parts of SBS, 16-23 parts of saturated polyester resin, 5-15 parts of nitrile rubber buna, 6-14 parts of white carbon black, 16-20 parts of polystyrene, 8.5-9 partsof cobalt powder, 16-24 parts of calcium carbonate, 52-58 parts of white oil, 4-6 parts of a wear-resistant agent, 2.5-3.5 parts of an anti-ultraviolet agent, 1.5-1.9 parts of an antioxidant, 2.5-3 parts of a flame retardant and 2-5 parts of a treating agent. The surface of a formed TPR material is coated with a layer of the treating agent and the flame retardant, so the TPR is modified through the treating agent, good affinity can be formed among the TPR treating agent, chloroprene rubber with strong polarity and a polyurethane adhesive, a good bonding effect can be achieved, bonding problems of TPR soles are solved, and the flame retardant effect of the TPR material is better; the preparation method is simple, and effect is good; and the surface of the formed TPR material is coated withthe flame retardant and the treating agent, so the adding effect of the flame retardant and the treating agent is more prominent.

Description

technical field [0001] The invention belongs to the technical field of TPR preparation, and in particular relates to an improved TPR preparation method. Background technique [0002] TPR material is a thermoplastic rubber material. It is a kind of thermoplastic soft rubber material that has rubber elasticity without vulcanization and can be directly processed (such as injection molding, extrusion, blow molding, etc.). TPR material is based on thermoplastic styrene-butadiene rubber (such as SBS, SEBS). Add resins (such as PP, PS), fillers, plasticizers and other functional additives to blend modified materials, the color is transparent or off-white particles; the shape is particles, usually spherical, ellipsoidal and fine round Strip shape, bright surface, good reflective performance, rubber resilience and good wear resistance, excellent skid resistance and shock absorption performance, TPR material is softer and more comfortable than rubber, but the material tensile strengt...
