Abstract

The invention discloses a polyurethane rigid foam composition. The polyurethane rigid foam composition comprises a white material component and a black material component, wherein the white material component is prepared from the following raw material components in parts by weight: 60 to 100 parts of polyether polyol, 0.1 to 40 parts of polyester polyol, 1 to 5 parts of water, 1 to 2 parts of a catalyst NA700, 1 to 2 parts of silicone oil and 0.1 to 10 parts of a foaming agent; the black material component is isocyanate, and the index of the isocyanate in the polyurethane rigid foam composition is 1.05 to 1.20. According to the polyurethane rigid foam composition disclosed by the invention, the catalystNA700 is adopted, so that the polyurethane rigid foam composition with good stability can be obtained.

Description

technical field [0001] The invention relates to the technical field of polyurethane materials, in particular to a rigid polyurethane foam composition, a rigid polyurethane foam prepared from the rigid polyurethane foam composition, and a preparation method for the rigid polyurethane foam. Background technique [0002] Polyurethane is a general term for polymer compounds containing repeated carbamate groups in the main chain. This polymer material can be used to manufacture plastics, rubber, rigid and flexible foams, adhesives, coatings, paints and other products. Because of its excellent wear resistance, impact resistance, UV resistance and high and low temperature resistance, it is widely used in construction, automobile, light industry, textile, petrochemical, metallurgy, electronics, national defense, medical, machinery and many other fields. [0003] There are two types of polyurethane foam, soft foam and hard foam. The soft foam has an open-cell structure, and the hard ...
