Abstract

The invention discloses a polyurethane foam insulation material, which is composed of the following ingredients (by weight): 80-100 parts of a polyurethane prepolymer, 100-120 parts of isocyanate, 15-20 parts of spirulina small molecule peptide, 5-10 parts of a microencapsulated phase change material, 15-30 parts of deionized water, 5-8 parts of stearic acid modified perlite, and 3-5 parts of epoxidized methyl acetoricinoleate. The polyurethane foam insulation material has good mechanical properties and heatproof heat-retaining property, water resistance and yellowing resistance, and overcomesthe insufficiencies of all-water foaming rigid polyurethane foam plastic, such as crispy foams and large heat conductivity coefficient.

Description

technical field [0001] The invention belongs to the technical field of organic composite materials, and in particular relates to a polyurethane foam insulation material. Background technique [0002] Polyurethane material is the abbreviation of polyurethane, which is a kind of polymer material. Polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and is widely used in many fields of the national economy because of its excellent performance. Foam plastic is one of the main varieties of polyurethane synthetic materials. Its main feature is porosity, so its relative density is small and its specific strength is high. According to the different raw materials and formula changes, it can be made into soft, semi-rigid and rigid polyurethane foams; if classified according to the types of polyols used, it can be divided into polyester type, polyether type and castor oil Polyurethane foam plastics, etc.; if classified according to the foaming m...
