Description
Technical field
The present invention relates to polyurethane heat insulation material.
Background technology
Polyurethane heat insulation material is the current best lagging material of performance in the world.Hard polyaminoester has that quality is light, thermal conductivity is low, good heat resistance, ageing-resistant, easily and other base material cohere, burn and do not produce the excellent properties such as molten drop, in American-European countries, be widely used in the roof, body of wall, top ceiling, floor, door and window etc. of buildings as heat preserving and insulating material.In the building thermal insulation material of the developed countries such as America and Europe, approximately have 49% for polyurethane material, this ratio of Er China is less than 10% still.
Polyurethane heat insulation material, as a kind of macromolecular material of excellent performance, has become the fifth-largest plastics after polyethylene, polyvinyl chloride, polypropylene, polystyrene, and global ultimate production is 10 million ton/year.China's polyurethane industrial has obtained tremendous development in recent years, in fields such as refrigerator, freight container, leather, shoemaking and weavings, has obtained widespread use; And this time the wideling popularize of the fields such as building energy conservation, Jiang Wei China Polyurethane Industry is created huge development space.
Intensity hard polyurethane foams cold insulation pipe carrier is that to take polyfunctionality organic isocyanate and admixtured polyether polyvalent alcohol be main raw material.Under the condition of catalyzer and the existence of multiple special additive, interact, a kind of rigid urethane foam making through complicated chemical reaction.In production of articles process, owing to having selected the urethane raw of specific larger functionality, and science is selected screening promoter material and material proportion, effectively improved goods ultimate compression strength, and the cold insulation pipe carrier goods physicochemical property making can meet requirements in application art completely, through relevant authoritative department, detect, indices meets or exceeds same kind of products at abroad state of the art, its goods tool has the following advantages: density is high, can be according to different application occasion, density regulates at 200 ~ 500 kilograms/cube, compressive strength is large, can reach 4 ~ 20MPa, thermal conductivity 0.052. has low thermal conductivity, low moisture permeable coefficient, low water absorption, meet cold insulation requirement.There is stability to hydrolysis resistance, anti-aging, the pharmaceutical chemicals excellent propertys such as acid and alkali-resistance, nonflammable, flame retardant resistance meets national security requirement density requirements;-165 degree-180 degree conduit saddle density are between 300-500.
