Abstract
One-can urethane coating; mainly by tolylene diisocyanate, 6305 polyethers, 3010 polyethers, dimethylbenzene, cross linking agent polyoxyethylene glycol, ester class or mineral acid stablizer and pigment (adopting the physico-chemical processes dehydration); has the reaction times weak point; product colourity is shallow; reaction process is easy to control; good stability; easy to use; low power consumption and other advantages; can be widely used in the decoration and the protection of woodenware, rubber and plastic, leatherware, instrument etc.; be the senior wear-resisting waterproof paint of a kind of ideal, bigger implementary value and economic results in society are arranged.
Description
The invention belongs to polyurethane coating, especially monocomponent moisture cure type polyurethane coating is applicable to the decoration and the protection of woodenware, rubber and plastic, leatherware, instrument etc.
Before the present invention makes, the polyurethane coating of prior art has the ammonia ester oil of single component, moisture curing, the catalyzer of dead front type and two-pack solidifies with polyol and solidifies five classes, the colored paint of prior art mainly is a polyol solidified two component polyurethane, it is a kind of that wherein monocomponent moisture cure type polyurethane coating only has varnish, existing monocomponent moisture cure type polyurethane varnish is wear-resistant paint, major ingredient is diphenylmethanediisocyanate (MDI), 625 polyethers (or polyester), Resins, epoxy, dimethylbenzene, therefore the reaction times reaches 8-16 hour, product colour dark (colourity 16-17 number), because no emergency control means in the reaction process, the gum deposit phenomenon appears unavoidably to cause product rejection, and product stability is relatively poor, and be 6 months general storage period; Adopt solvent to distill or oven dry because the pigment dehydration is conventional, energy consumption is high, if pigment dehydration unclean (requiring less than 0.1%), single-component moisture curing polyurethane colored paint are solidified in a short time easily lost efficacy, so still do not have this type of single-component moisture curing polyurethane colored paint supply on the market.
Task of the present invention is the shortcoming that overcomes prior art, provide a kind of reaction times short, prevent gum deposit, energy consumption is low, colourity is shallow, stability better and one-can urethane coating easy to use.
One-can urethane coating, it is characterized in that mainly by tolylene diisocyanate (TDI), 6305 polyethers, 3010 polyethers, dimethylbenzene, cross linking agent polyoxyethylene glycol, ester class or mineral acid stablizer and pigment, the component of this coating contains tolylene diisocyanate 10-40%(weight), 6305 polyethers 10-25%(weight), 3010 polyethers 5-32%(weight), dimethylbenzene 40-60%(weight), polyoxyethylene glycol 0.1-2.0%(weight), ester class or mineral acid 0.01-0.5%(weight), pigment (water content＜0.1%) 0-30%(weight).
Principle of the present invention and embodiment are: adopt tolylene diisocyanate, 3010 polyethers and 6305 polyethers, dimethylbenzene is basic raw material, after adding the cross linking agent polyoxyethylene glycol, temperature of reaction reaches 80-100 ℃, reaction times is shortened greatly, usually shorten to 2-3 hour, make simultaneously to obtain product colourity shallow (colourity 3-4 number), add ester class or mineral acid stablizer, energy emergency control reaction process, prevent the product gum deposit, improve the stability of product, increased the period of storage of product, be generally 9 months, pigment adopts the physico-chemical processes dehydration, the pigment water content is reduced to below 0.1%, guaranteed the stability that product is stored, the single-component moisture curing polyurethane colored paint is achieved, can not produce short-term solidifies, it is also comparatively convenient to use, and energy consumption is low, has bigger implementary value.
Each composition weight % composition of one-can urethane coating of the present invention (varnish) is seen embodiment 1, implements 2, is implemented 3:
Embodiment 1:
Tolylene diisocyanate 33%(weight)
6305 polyethers 20%(weight)

Polyoxyethylene glycol 0.35%(weight)
Phosphoric acid 0.05%(weight)
The operation steps of embodiment 1, embodiment 2, embodiment 3 is:
Tolylene diisocyanate is squeezed in the stainless steel cauldron, add 6305 polyethers, 3010 polyethers and dimethylbenzene successively, stir the while heat temperature raising to 80-100 ℃, add the polyoxyethylene glycol cross linking agent again, total reaction time 2-3 hour, when viscosity reaches about 20 seconds, add phosphoric acid or how get final product discharging behind the ester stabilizer, filter and package.
One-can urethane coating of the present invention (colored paint), each composition weight % composition is seen embodiment 4:
Embodiment 4:
The standard recipe of white paint (weight %)
Varnish paint vehicle 71.8
Titanium dioxide (water content＜0.1%) 25
Ultramarine (water content＜0.1% 0.2
Dimethylbenzene 3
The operation steps of embodiment 4 is:
Dewater with physico-chemical processes earlier, make pigment titanium white, ultramarine water content less than 0.1%, 30% varnish paint vehicle of total amount is carried out high speed dispersion with pigment respectively, grinds and make mill base, after fineness reaches 20 μ, varnish paint vehicle, the dimethylbenzene that adds residue 70% is again mixed and is stirred well evenly, filters the back packing.
One-can urethane coating of the present invention compared with prior art, has the reaction time greatly to shorten; product colourity is shallow; can the emergent control course of reaction, prevent the product gum deposit, improve product stability and period of storage; can not produce short-term solidifies; easy to use, low power consumption and other advantages can be widely used in decoration and the protection of woodenware, rubber and plastic, leather and fur products, instrument and meter etc.; be a kind of desirable senior wear-resisting water-repellent paint, have bigger implementary value and economic results in society.
