Problems solved by technology

[0003] However, with the global energy shortage and the continuous changes in national policies, the performance requirements for polyurethane rigid foam are also continuously increasing. Traditional polyurethane rigid foam has relatively poor thermal insulation performance and strength, and it is difficult to meet the country's increasing energy conservation and environmental protection standards.

Abstract

The invention discloses a rigid polyurethane foam composition, a rigid polyurethane foam material, and a preparation method of the rigid polyurethane foam material. The rigid polyurethane foam composition is prepared from the following components in parts by weight: 60-70 parts of polyether polyol, 30-40 parts of polyester polyol, 1-3 parts of water, 0.1-0.5 part of a catalyst, 1-3 parts of silicone oil, 0.2-1.5 parts of nano metal oxide, 0-10 parts of a foaming agent, and 110-140 parts of isocyanate. According to the rigid polyurethane foam composition disclosed by the invention, the nano metal oxide is added, so that the heat conductivity coefficient of the rigid polyurethane foam material is decreased compared with a traditional rigid polyurethane foam material, and further the compression performance of the rigid polyurethane foam material is improved; the heat stability is good, foam pores are fine, the dimensional stability is good, and the strength is high; the yellowing degreeof the rigid polyurethane foam material can be effectively reduced, the rigid polyurethane foam material is not liable to be yellowed, the attractiveness of the light-colored polyurethane material isnot affected, and the aesthetic requirements of people are met.
