Description
Technical field
The present invention relates to two-component spraying polyurethane foam field, relate in particular to a kind of composition of low temperature spraying polyurethane heat-insulation foam.
Background technology
Polyurethane foam is with superior performance and use handiness to become the important component part of heat-insulating construction material, and its principal character is porousness, thereby relative density is little, good heat preservation performance, and specific tenacity is high.According to raw material used, different and formula changes, and can be made into soft, semi-rigid and hard polyurethane foams etc. several; As building thermal insulation material compared with similar products, polyurethane foam bonding is strong, shockproof compression-resistant, have very low temperature thermal conductivity, sound insulation etc., thereby is used in a large number in building decoration.Just because of there is such advantage, become one of indispensable material.
The foam materials using at present is mostly all that prefabricated foam board is bonded on construction wall, make like this to install consuming time, need binding agent, have seam, the more difficult construction of random body of wall etc.; In recent years the polyurethane spray foam that starts development overcomes preferably above shortcoming and obtains good promotion and application.Polyurethane spray foam is that the raw materials such as polyvalent alcohol, isocyanic ester, water, catalyzer, tensio-active agent and other additives are formed, in use, by first component, it is polyvalent alcohol, component B is that isocyanic ester enters mixing ejection in spray coating mechanical, be vaporific, foamed set moulding obtains polyurethane spray foam within a certain period of time.
Polyurethane spray foam except have polyurethane foamed material a little, have a little;
1, because of in-situ spraying, form integral waterproofing layer, there is no seam, any polymer coiled material can't be obtained, reduces maintenance load.
2, without binding agent.By material direct spraying on base material, foaming after and base material have better cohesive strength, reduced cystose and used required binding agent,
3, for the maintenance of new work roofing or old roof all very suitable particularly old roof reprocess, needn't root out original waterproof layer and thermal insulation layer, only need to remove surperficial ash, sand foreign material, can spray.
4, easy construction speed is fast.Construction is simple, and applicable big area is constructed continuously.
5, receipts head structure is simple.Spray coating foaming urethane is received head, need not process especially, greatly simplifies.8. good in economic efficiency.
Having at present polyurethane spray foam body material is that polyol component and isocyanate component form, but (below 10 ℃) the two even foaming of component frothing percentages reduction at low temperatures of general polyvalent alcohol and isocyanic ester.While therefore using, be obviously subject to the restriction of seasonal temperature.Expansion rate problem, polyurethane foam mainly relies on polyvalent alcohol and the id reaction of isocyanic ester under the effect of catalyzer, its speed depends on height and catalyst type and the consumption of temperature largely, if speed is too fast during spraying polyurethane foaming, make the outward appearance of foam and pure in problem with the sticking power of bottom, if cross slowly, when being used, facade just there will be so the phenomenons such as sagging.
Urethane is met fire and can be burnt and decompose, and produces a large amount of toxic smogs, to fire extinguishing, brings difficulty.Particularly flexible PU foam percentage of open area is higher, and combustiblecomponents is many, during burning due to the air circulation compared with high oxygen gas-supplying continuously, inflammable and difficult from putting out.Many Application Areass of urethane foam, as material of construction, mattress, furniture, lagging material, seat cushions and interior material etc., have fire-retardant requirement.And current polyurethane heat-insulation foam for building has flame retardant resistance hardly.
Summary of the invention
Goal of the invention of the present invention is to address the above problem, and provides a kind of normally foaming at low temperatures, environmental protection, fire-retardant low temperature to spray the composition of polyurethane heat-insulation foam.
