Abstract

The invention discloses a preparation method and a construction process for a colorful polyurethane plastic track, and belongs to the technical field of sports facilities. The preparation method for colorful polyurethane plastic comprises the following steps: uniformly stirring 10 to 15 parts of polyether polyol, 10 to 30 parts of hydroxylated acrylic resin, 10 to 30 parts of paraffin, 2 to 4 parts of a chain extender and 0.1 to 0.5 part of an age resistor, and raising temperature to 90 to 100 DEG C; adding 30 to 50 parts of a filler, 2 to 9 parts of a pigment and 0.1 to 0.5 parts of an age resistor, and performing uniform stirring; starting a colloid grinder to grind the materials into particle sizes of smaller than 400 meshes; continuing heating, and performing dehydration for 2 to 3 hours under the conditions of temperature of 90 to 100 DEG C and vacuum degree of lower than 0.095Mpa. According to the preparation method and the construction process, with the adoption of the high-functionality polyether polyol, reaction is accelerated, the hardness of a formed film is increased, and construction time is shortened; by the hydroxylated acrylic resin, high glossiness and higher weather resistance and color retention are achieved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a method for making colorful polyurethane plastics and a construction technique for a runway made of colorful polyurethane plastics, belonging to the technical field of sports facilities. Background technique [0002] Plastic track, also known as all-weather track and field track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as the bes...
