Abstract

The invention discloses a polyurethane heat-insulating material, which comprises the following components in percentage by weight: 8-9% of toluene diisocyanate, 3-4% of modified polyether glycol, 0.03-0.05% of dibutyltin dilaurate, 0.5-1.5% of 1,4-butanediol, 1-2% of water, 1-2% of trimethylolpropane, 3-8% of chlorofluorocarbon, and the balance of polymethylene polyphenyl polyisocyanate.

Description

A kind of polyurethane heat insulation material and preparation method thereof
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, and in still less than 10% of this ratio of China.
The urethane that is called " New Times environment-friendly materials " by construction industry carries out crosslinking reaction foaming by hard polyethers, auxiliary agent and polyisocyanates and prepares, it is a kind of novel adiabatic heat-insulation rot-resistant high molecular synthetic material, has lower water vapor permeation coefficient and good watertightness.It is a kind of low density micropore polymer porous plastics with unicellular structure, integrates insulation and water-proof function, has very strong adhesive property with metal, timber, cement, masonry, glass etc.Meanwhile, its raw materials for production reactivity worth is high, has good mobility, can successfully be full of between the die cavity and chamber of complicated shape, and curing speed is fast, can in factory, realize the large batch of production of high-level efficiency.Traditional whipping agent refers to freonll-11, and it has another name called freon, is the organic compound that contains fluorine and chlorine.Their penetrating power is very strong, easily gas leakage, and be difficult for finding.This gas runs into naked light or temperature and reaches 400 ° of C when above, just resolves into poisonous hydrogen fluoride and hydrogenchloride, and emits poisonous phosgene.The more important thing is that this gas can also damage the ozone layer, and makes ozonosphere cause cavity.Its price, has corrosive nature to rubber, plastics, has forbidden in the world now that F-12 and freonll-11-1 remake cooling agent and uses, but the row that is not forbidding freonll-11-22.Whipping agent not only has serious destruction to the ozonosphere in atmospheric layer, in foaming process, also can produce and be harmful to healthy gas.
Summary of the invention
The invention provides a kind of polyurethane heat insulation material and preparation method thereof.
The present invention is achieved through the following technical solutions:
A kind of polyurethane heat insulation material, is characterized in that being comprised of by weight following component:
Tolylene diisocyanate 8-9%, modified polyether polylol 3-4%, dibutyl tin laurate 0.03-0.05%, Isosorbide-5-Nitrae butyleneglycol 0.5-1.5%, water 1-2%, trihydroxy methyl propane 1-2%, Chlorofluorocarbons (CFCs) 3-8%, all the other are poly methylene poly phenyl poly isocyanate.
Be preferably tolylene diisocyanate 9%, modified polyether polylol 3%, dibutyl tin laurate 0.04%, Isosorbide-5-Nitrae butyleneglycol 1%, water 1%, trihydroxy methyl propane 1%, Chlorofluorocarbons (CFCs) 6%, all the other are poly methylene poly phenyl poly isocyanate.
Technique of the present invention is simple, easy to operate, environment-friendly and green, and ozone layer destroying effect ODP value is zero, has no side effect, full water bubble preparation technology is easy, very low to the requirement of equipment, can continue to use the equipment of CFC-11 or HCFC-141b system; Biobased polyether polyol has unique performance in full water foamed, and the lagging material of making is without phenomenons such as contraction, distortion, expansions when normal temperature, 100 ° of C of high temperature, low temperature-25 ° C, and stability is high, and thermal conductivity is low.
The lagging material thermal conductivity 0.024 that the present invention makes; Oxidation index 28; Rate of closed hole 99.5; Water-intake rate 1; Intensity 10MPa is high-quality lagging material.
