Abstract
The invention relates to a process for preparing a breathe-freely coating adhesive of waterborne polyurethane siloxane for cars and shoes. The invention is characterized in that the process includes that firstly producing a preformed polymer body with terminal group of -NCO by diisocyanate, hydroxymethyl silicon oil and polyester polyol, then using dimethylol propionic acid and diglycol ethylene for chain reaction, finally adding ionized water and blending after pH is adjusted to be neutral by salifying agent, and then adding silane coupling agent, removing acetone, consequently the breathe-freely coating adhesive of waterborne polyurethane siloxane for cars and shoes is obtained. The invention employs organo-silicone to graft polyurethane, and the softness and abrasive resistance for utilization are obviously improved. The coating adhesive enables leathers for cars and shoes to have relatively sound characteristics of softness, abrasive resistance, lubrication, breathe-freely property and brightness, thereby the invention can be applied to the superficial treatment of cars and shoes and the like products.
Description
Technical field
The present invention relates to the preparation method of a kind of automobile, footwear use polyurethane siloxane ventilating coating adhesive, be mainly used in the surface treatment of automobile and footwear product.Belong to the auxiliary chemicals technical field.
Background technology
Automobile, footwear use leather to go up coating adhesive commonly used be the solvent-borne type product mostly, very not environmental protection, and generally aqueous coating glue is water-and acrylate class or polyurethanes product, and environmental protection, but its luminance brightness, pliability are bad, not wear-resisting.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of flexibility that can not only obviously improve use and wear resistance, but also the automobile of environmental protection, the preparation method of footwear use polyurethane siloxane ventilating coating adhesive are provided.
The objective of the invention is to realize like this: the preparation method of a kind of automobile, footwear use polyurethane siloxane ventilating coating adhesive; It is characterized in that: said method is: use earlier vulcabond, methylol silicone oil and polyester polyol to generate the performed polymer of end group, use dimethylol propionic acid and glycol ether chain extending reaction then for-NCO, at last with salt forming agent adjusting pH value to neutrality; Add ionized water; Stir, add silane coupling agent again, promptly obtain the aqueous polyurethane siloxane ventilating coating adhesive.The concrete technology of said method is: in the reaction vessel of belt stirrer, add polyester polyol, vulcabond and methylol silicone oil, 80-85 ℃ of reaction 1.5-2 hour, be cooled to 70-75 ℃; Add dimethylol propionic acid (DMPA) and glycol ether chain extending reaction, insulated and stirred 30-40min drips the dibutyl tin dilaurate that accounts for vulcabond weight 0.08-0.12%; Add the acetone that accounts for total system weight 8-12% weight percent and reduce system viscosity,, reduce to room temperature 60-65 ℃ of insulation 4.5-5 hour; Add in the triethylamine and after; Add ionized water, stir, add silane coupling agent again; Slough acetone, promptly obtain the aqueous polyurethane siloxane ventilating coating adhesive.
Said each raw material reacts according to following proportioning:
-NCO :-OH=1.5-4: 1 (mol ratio), wherein-and NCO representes NCO ,-OH representes the hydroxyl of polyester polyol.
The mol ratio of dimethylol propionic acid and polyester polyol is 0.3-1: 1.
