Abstract
The invention discloses a polyurethane heat insulation material, which is prepared from the following raw materials in parts by weight through foaming: 60 to 80 parts of toluene diisocynate, 40 to 60 parts of plant fiber based polyether polyol, 30 to 50 parts of plant oil based polyether polyol, 1 to 3 parts of catalysts, 0.5 to 1 part of foaming agents, 1 to 3 parts of silicone oil and 6 to 8 parts of deionized water. The polyurethane heat insulation material has the advantages of high intensity, light weight, low heat conductivity, good dimension stability, good heat insulation effect, good wear-resistant anti-corrosion performance and efficient flame-retardant capability; polyhydric alcohols are prepared from waste, waste grease and the like; the energy is saved; the environment is protected. In addition, the preparation process is simple; the cost is low; the equipment requirements are low; the environment-friendly effect is achieved in the production process; the industrial production is easy; the polyurethane heat insulation material is suitable for large-range popularization and application.
