Abstract

The invention provides polyurethane high-resilience foam and a preparation method thereof. The polyurethane high-resilience foam is prepared from the following raw material components in parts by weight: 68 to 75 parts of isocyanate, 90 to 100 parts of polyhydric alcohol, 1 to 2 parts of a foam stabilizer, 0.2 to 1.2 parts of a cross-linking agent, 2.5 to 4 parts of water, 0.28 to 1.58 parts of acatalyst, 18 to 24 parts of calcium carbonate and 0.5 to 3 parts of an anionic surfactant. Through mutual cooperation of the components, the polyurethane high-resilience foam with high tear resistance, high bearing performance and high calcium carbonate filling amount is finally obtained, and cheap calcium carbonate is used as a filler, so that the cost is saved under the condition that the tear resistance and the bearing performance of the product are improved, and large-scale production and promotion are facilitated.

Description

technical field [0001] The invention relates to the field of polyurethane materials, in particular to a polyurethane high-resilience foam and a preparation method thereof. Background technique [0002] Polyurethane high-resilience foam is a kind of flexible foam with excellent performance. In addition to the advantages of light weight, softness and high specific strength of ordinary soft foam, it also has higher resilience, high comfort and performance durability. At present, polyurethane high-resilience foam is mostly used to make seat cushions. It is an ideal material for paving and cushioning, and has a wide range of applications in the automotive industry and furniture industry. [0003] Polyurethane high-resilience foam is obtained by the reaction of polyols and isocyanates under the action of crosslinking agents and catalysts. In order to improve the load-bearing performance of polyurethane high-resilience foam, obtain better cell opening effect and reduce the overall ...
