The polyether composition includes polyether glycol with hydroxyl value of 250-500 mgKOH/g and functionaliy degree of 2-3 in 40- 60 wt%, polyester glycol with hydroxyl value of 200-400 mgKOH/g and functionaliy degree of 2-3 in 20-40 wt%, dimethyl formamide 5-10 wt%, chlorinated paraffin 10-20 wt%, surfactant 1-2 wt%, and dimorpholinyl dihexyl ether 1-2 wt%; and the isocyanate includes toluene diisocyanate (TDI) 30-50 wt%, and multimethyl diisocyanate (MDI) 50-70 wt %. The present invention has high stability, low temperature tolerance, low cost and good gap filling effect, and may be used widely in building.
Description
Affiliated technical field the present invention relates to a kind of sealing agent of single component polyurethane foam, can be widely used in the building material industry.
The existing sealing agent of single component polyurethane foam of background technology, owing to adopt full MDI system, and MDI has intensive closed pore tendency, adding foam is a kind of soft body, under barometric point, the formed foam of traditional foam gap filler shrinks easily.Therefore, there is not low temperature resistant, bad, the easy contraction of stability in product, the foam contraction rate is bigger than normal, the foam hole thick, foam is fineless and smooth, the problem of skin depth, inhomogeneous, poor dimensional stability, joint filling weak effect.
Summary of the invention the object of the present invention is to provide a kind of good stability, resistance to low temperature is good, product cost is low, joint filling is effective sealing agent of single component polyurethane foam.
In order to achieve the above object, sealing agent of single component polyurethane foam of the present invention comprises combined polyether (hereinafter to be referred as A) and isocyanic ester (hereinafter to be referred as B); Said combined polyether comprises polyether glycol hydroxyl value mgKOH/g 250～500 functionality 2～3, hydroxyl value of polyester polyol mgKOH/g 200～400 functionality 2～3, dimethyl formamide (DMF), clorafin, tensio-active agent, dimorpholine hexyl ether; Said isocyanic ester comprises Xylene Diisocyanate (TDI), many methyl isocyanates (MDI);
(a) each component of combined polyether and weight content are:
Polyether glycol hydroxyl value mgKOH/g 250～500 functionality 2～3 40%～60%
Hydroxyl value of polyester polyol mgKOH/g 200～400 functionality 2～3 20%～40%
Dimethyl formamide (DMF) 5%～10%
Clorafin 10%～20%
Tensio-active agent 1%～2%
N,N-Dibenzylamine (DMDEE) 1%～2%;
(b) each component of isocyanic ester and weight content are:
Xylene Diisocyanate (TDI) 30%～50%
Many methyl isocyanates (MDI) 50%～70%;
(c) isocyanic ester and the combined polyether part by weight in monocomponent bubble spackling production can:
B∶A＝0.4～1.3。
Sealing agent of single component polyurethane foam of the present invention, use special special-purpose aerosol filling machine, combined polyether, isocyanic ester, be poured in the aerosol container and go successively, press valve then, charge into propelling agent (third butane) more successively, then tank body is waved mixing, place again after 24 hours and promptly can use.
Pass through filling process, polyurethane foam starting material and aerosol propellant are filled to aerosol with in the pressure-pot, and when opening valve, the good foam of reaction sprays under the promotion of propelling agent outside the jar in jar, reflection is solidified behind the moisture in the middle of the absorption air, plays the effect of joint filling.
Sealing agent of single component polyurethane foam of the present invention, the used polyethers of monocomponent moisture cure foam gap filler are semihard bubble, elastomeric polyethers, use the formed foam in back softer; After adding use MDI and TDI compound,, can satisfy dimensional stability and thermal conductivity requirement because the perforate performance of TDI is good.Therefore, formed froth stability is good.
Sealing agent of single component polyurethane foam of the present invention is compared with the conventional urethane foam gap filler, and the formed foam of conventional urethane foam gap filler solidifies slowly during low temperature in the winter time, causes quality problems easily.And the present invention is because to have the polyester polyol activity of fragrant hydroxyl good, and foam also has the characteristics of quick solidifying cryogenic the time, therefore, can also use during low temperature in the winter time, broken the use restriction of temperature to spackling, and resistance to low temperature is good.
Sealing agent of single component polyurethane foam of the present invention, the use of softening agent clorafin and DMF, one side can reduce the cost of product significantly, has also played the effect of viscosity-depression agent on the other hand, has improved product foamy performance.
Sealing agent of single component polyurethane foam of the present invention, N,N-Dibenzylamine (DMDEE) plays a part catalyzer.This catalyzer has stronger katalysis, and good package stability is arranged again.
Sealing agent of single component polyurethane foam of the present invention, usually, Polyetherfunctional degree and hydroxyl value are big more, and the polyurethane prepolymer viscosity that then makes is big, and the gained foam is hard, and density is big, and bonding strength is big, and dimensional stability is good; Otherwise if Polyetherfunctional degree and hydroxyl value are little, then polyurethane prepolymer viscosity is little, and the gained foam is soft, and density is little, and bonding strength is low, poor dimensional stability.The present invention adopted functionality less than 5, hydroxyl value is the polyethers of 250～500mgKOH/g, the gained foam has suitable over-all properties thus.
Sealing agent of single component polyurethane foam of the present invention need not the special training operative employee, and is easy to use.Automatically ejection does not need cast equipment, and the pressure in the aerosol jar can be injected into material the required slit of filling out envelope automatically.Automatically expand, can expand automatically is filled into each corner by the joint filling crack.Moisture-curable need not auxiliary curing agent, and is promptly curable by airborne moisture.Automatically bonding does not need pre-treatment is carried out on the surface, and to base material, there is advantages of good caking property on particularly wet surface.
Sealing agent of single component polyurethane foam of the present invention, have multiple effects such as joint filling, bonding, sealing, heat insulation, sound-absorbing, be a kind of environmental protection and energy saving, material of construction easy to use, applicable to sealing and plugging, fill a vacancy squeegee, fixing bonding, heat preservation and soundproof, be particularly useful for sealing and plugging and waterproof between plastic-steel or aluminum alloy doors and windows and body of wall.
In sum, and the experiment proved that, sealing agent of single component polyurethane foam of the present invention, cost is low, and the foam hole is fine and closely woven, and foam expansion is big, and is low temperature resistant, good stability, foam exquisiteness, even, joint filling is effective.
Embodiment sealing agent of single component polyurethane foam of the present invention comprises combined polyether (hereinafter to be referred as A) and isocyanic ester (hereinafter to be referred as B); Said combined polyether comprises polyether glycol hydroxyl value mgKOH/g 250～500 functionality 2～3, hydroxyl value of polyester polyol mgKOH/g 200～400 functionality 2～3, dimethyl formamide (DMF), clorafin, tensio-active agent, dimorpholine hexyl ether; Said isocyanic ester comprises Xylene Diisocyanate (TDI), many methyl isocyanates (MDI); Each component and weight content are:
