Abstract
The invention provides a foaming agent composition composed of trans-1,2-dichloroethylene and at least one of polyalcohol or polyhydroxyl compounds, wherein the content of the trans-1,2-dichloroethylene is higher than 1 mol% and not higher than 25 mol%. The trans-1,2-dichloroethylene is directly substituted for HCFC-141b as the foaming agent, thereby obtaining the satisfactory foam product.
Description
Technical field
The present invention relates to a kind of foaming agent composotion containing trans-1,2-dichloroethene.
Background technology
The production method of urethane or polyisocyanurate foam is well-known, generally consist of under a kind of existence of volatile foaming agent, the reaction of a kind of organic multiple isocyanate (comprising vulcabond) and a kind of many alcohol or many alcohol mixtures, this whipping agent can volatilize because of the heat discharged between isocyanic ester and many alcohol reaction period, by the use of amine or other catalyzer and tensio-active agent, this reaction can be strengthened, catalyzer can guarantee that these foams fully solidify, the size in tensio-active agent then controllable foam hole, add the combustibility that fire retardant then can reduce foams.
In many applications, be by foam-body material in advance mixture become two kinds of components, isocyanic ester or polyisocyantates composition are included in the first component, usually become " A " component; The substance mixture such as many alcohol or many alcohol mixtures, tensio-active agent, catalyzer, whipping agent, fire retardant are included in second component, usually become " B " component.Just urethane or polyisocyanurate foam can be prepared easily by component A and B component being mixed.
Once by trichlorofluoromethane (CFC-11) widely used as whipping agent, because it can destroy atmospheric ozone layer, now by performance and its fluorine ethylene dichloride (HCFC-141b) relatively substitute.But the ODP of HCFC-141b is non-vanishing, still can damage atmospheric ozone layer, therefore Montreal Protocol is listed in and is eliminated in the works.Some developed countries eliminate HCFC-141b in advance, and China will eliminate HCFC-141b in the near future.The surrogate substituting now HCFC-141b in the world mainly contains 1,1,1,3,3-3-pentafluorobutane (HFC-365mfc), 1,1,1,3,3-pentafluoropropane HFC-245fa, 1,3,3,3-tetrafluoeopropene (HFO-1234ze) etc., the manufacture patent of above-mentioned substance all monopolize by major companies such as Zoomlion A Kema, Honeywell, Baeyer, Tao Shi, Du Ponts, in addition production cost is high, promotes slowly.
A kind of foaming agent of market active demand, it is alternative HCFC-141b not only, and is not again the material of the destruction atmospheric ozone layer that the restriction of the existing world uses, simultaneously moderate, can avoid the whipping agent product of foreign patent monopolization.
Summary of the invention
the problem that invention will solve
The object of the invention is to provide the foaming agent composotion containing trans-1,2-dichloroethene.
for the scheme of dealing with problems
Be selected from by trans-1,2-dichloroethene and at least one the foaming agent composotion that polyvalent alcohol or polyol form, wherein, the content of trans-1,2-dichloroethene is more than 1 % by mole and not higher than 25 % by mole.

Preferably, foaming agent composotion, described polyol is selected from the one in polyoxypropylene polyether polyol, alkaline polyol, aromatic amine polyoxytrimethylene ether polyol.
The present invention also provides a kind of rigid foam, is mixed obtained by polyhydric alcohol composition, phosphoric acid trichlorine isopropyl ester, dimethylcyclohexylamine, silicone polyoxyalkylene hydrocarbon copolymer, water, trans-1,2-dichloroethene and 4,4-vulcabond ditane.
The present invention also provides a kind of fire-retardant poly-isocyanide urea imide ester foam, by polyoxypropylene polyether polyol, phosphoric acid trichlorine isopropyl ester, Tetramethyl Ethylene Diamine, silicone polyoxyalkylene hydrocarbon copolymer, water, trans-1,2-Ethylene Dichloride and the mixing of 4,4-vulcabond ditane obtain.
The present invention also provides a kind of flexible polyurethane foam, is mixed obtained by alkaline polyol, BDO, phosphoric acid trichlorine isopropyl ester, Tetramethyl Ethylene Diamine, lauric acid two fourth tin, trans-1,2-dichloroethene and 4,4-vulcabond ditane.
The present invention also provides a kind of low density heat insulation foam, by aromatic amine polyoxytrimethylene ether polyol, polyoxytrimethylene polyol, five methyl diethylentriamine, N-alkyl morpholine, water, trans-1,2-Ethylene Dichloride and the mixing of 4,4-vulcabond ditane obtain.
the effect of invention
The anti-1,2-dichloroethene of whipping agent provided by the invention directly replaces HCFC-141b just can obtain gratifying froth product as whipping agent use.It is alternative HCFC-141b not only, and is not the material of the destruction atmospheric ozone layer that the restriction of the existing world uses, simultaneously moderate.
