Preparation method for colorful polyurethane plastic and construction process for colorful polyurethane plastic track
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.
