Abstract

The invention belongs to the plastic field and discloses modified polyurethane expanded plastic and a preparation method thereof. The modified polyurethane expanded plastic is prepared from 120 to 150 parts by weight of isocyanate, 100 to 120 parts by weight of polyester polyol, 20 to 30 parts by weight of a glass fiber cloth, 0.6 to 1 part by weight of a silane coupling agent, 0.4 to 0.8 parts by weight of a titanate coupling agent, 0.6 to 1 part by weight of monoglyceride, 3 to 5 parts by weight of triethanolamine, 10 to 20 parts by weight of carbon nanotubes, 20 to 30 parts by weight of low-density polyethylene, 20 to 30 parts by weight of aramid pulp, 10 to 20 parts by weight of ceramic fibers, 1 to 2 parts by weight of azodicarbonamide, 0.3 to 0.5 parts by weight of a foam stabilizer, 1 to 2 parts by weight of sodium dodecyl sulfate and 0.6 to 1 part by weight of an antioxidant. The modified polyurethane expanded plastic has the advantages of uniform bubbles, light weight, good toughness, wear resistance, anisotropy and excellent thermal insulation performances.

Description

technical field [0001] The invention belongs to the technical field of plastics, and relates to a modified polyurethane foam plastic, and also relates to a preparation method of the modified polyurethane foam plastic. Background technique [0002] Polyurethane material is currently the best performance insulation material in the world, which is polymerized from isocyanate (monomer) and hydroxyl compound. Due to the extremely strong urethane group, it is insoluble in non-polar groups and has good oil resistance, toughness, abrasion resistance, aging resistance and adhesion. [0003] Polyurethane foam plastic is a good raw material, which is a foam product made of polyether polyol and isocyanate under the action of a blowing agent. It has excellent thermal insulation properties, mechanical properties, electrical properties, acoustic properties and chemical resistance. etc., are widely used in refrigerators, freezers, building energy-saving, sofas, mattresses, shoe materials, ...
