Abstract

The invention relates to foam materials and particularly relates to high-damping high-strength polyurethane foam. The polyurethane foam comprises the following ingredients in parts by weight: 50 partsof polyethylene glycol 400, 20-30 parts of polyester polyol, 5-10 parts of hydroxyl-fluoro silicone oil, 80-100 parts of isocyanate, 20-35 parts of boron-titanium-magnesium whiskers, 10-25 parts of ammonium polyphosphate, 1-3 parts of triethylene diamine, 0.5-3 parts of water and 0.05-0.25 part of tin dibutyl dilaurate. The polyurethane foam has the following beneficial effects that the mechanical properties of the polyurethane foam are effectively improved; the coefficient of damping is high, and thus, the polyurethane foam has a good damping buffering effect; the polyurethane foam has superhydrophobic performance and is high in stain resistance.

Description

technical field [0001] The invention relates to a foam material, in particular to a high-damping high-strength polyurethane foam. Background technique [0002] Polyurethane foam is made of isocyanate and hydroxyl compound through polymerization and foaming. According to its hardness, it can be divided into two types: soft and hard, of which soft is the main variety. Generally speaking, it has excellent elasticity, softness, elongation and compressive strength; good chemical stability, resistance to many solvents and oils; excellent abrasion resistance, 20 times larger than natural sponge; and excellent processing It is a kind of cushioning material with excellent performance, such as thermal insulation, adhesiveness and so on. [0003] According to the survey, my country's polyurethane foam industry has developed rapidly, especially in market development. The rapid development of domestic refrigeration and heat preservation, building energy saving, solar energy industry, a...
