Abstract
The present invention relates to a kind of preparation method of aqueous polyurethane grafted siloxane wear-resistant soft finishing agent, it is characterized in that: described method is: earlier generate the performed polymer of end group for-NCO with vulcabond and di-alcohols compound, then with dihydromethyl propionic acid and 1, the reaction of 4-chain expansion of succinic acid, regulate the pH value to neutrality with triethylamine at last, add deionized water and stirring, promptly obtain aqueous polyurethane grafted siloxane wear-resistant soft finishing agent.The handled fabric of this finishing agent, ABRASION RESISTANCE is good, and is soft, and water-proof air-moisture-permeable is desirable fabric finishing agent.Another characteristics of the present invention are to bake the processing fabric by padding, and technology is simple, and process does not have the hazardous solvent volatilization.Meet the green technology requirement fully.
Description
Technical field
The present invention relates to a kind of preparation method of aqueous polyurethane grafted siloxane wear-resistant soft finishing agent, be mainly used in the spinning post-finishing.Belong to chemical textile auxiliary agent technical field.
Background technology
The soft air and moisture permeable fabric of environment-friendly type waterproof antiwear be always people wear pursue.Before the present invention made, weaving in the past mostly was silicone based softener greatly with softener, and what soft effect was best is to contain amino organosilicon.It gives the fabric sofetening function, and does not have resilience, wear-resisting functions, simultaneously because amino existence, makes the easy yellowing of fabric.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of preparation method with aqueous polyurethane grafted siloxane wear-resistant soft finishing agent of wear-resisting, soft effect is provided.
The object of the present invention is achieved like this: a kind of preparation method of aqueous polyurethane grafted siloxane wear-resistant soft finishing agent, it is characterized in that: described method is: earlier generate the performed polymer of end group for-NCO with vulcabond and di-alcohols compound, then with dihydromethyl propionic acid and 1, the reaction of 4-chain expansion of succinic acid, regulate the pH value to neutrality with triethylamine at last, add deionized water and stirring, promptly obtain aqueous polyurethane grafted siloxane wear-resistant soft finishing agent.The concrete technology of described method is: in the reaction vessel of belt stirrer, add diatomic alcohol compounds and vulcabond, reacted 1.5 hours-2 hours down at 80-85 ℃, be cooled to 70-75 ℃, add dihydromethyl propionic acid (DMPA) and 1, the 4-butanediol, insulated and stirred 30-40min, dropping accounts for the dibutyl tin dilaurate of vulcabond weight 0.08-0.12%, add the ethyl acetate or the acetone that account for total system weight 8-12% percentage by weight and reduce system viscosity, 60-65 ℃ of insulation 4.5-5 hour, reduce to room temperature, add in the triethylamine and after, add deionized water, stir, slough ethyl acetate or acetone, promptly obtain aqueous polyurethane grafted siloxane wear-resistant soft finishing agent.
Described each raw material reacts according to following proportioning:
-NCO :-OH=1.5-3: 1 mol ratio, wherein-and NCO represents isocyanate group ,-OH represents the hydroxyl of di-alcohols compound,
The mol ratio of dihydromethyl propionic acid and di-alcohols compound is 0.3-1: 1.
1, the mol ratio of 4-butanediol and di-alcohols compound is 0.8-1.5: 1.
Described vulcabond can be IPDI, HDI, TDI or MDI.
Described di-alcohols compound can be that molecular weight is that polyethylene glycol, polyethers 220, polyethers 210 or the molecular weight of 1000-2000 is the methylol silicone oil of 1000-3000.
The present invention is a kind of environment protection type single-component aqueous polyurethane.Has wear-resisting, soft effect.Owing to there is not amino existence, fabric can yellowing simultaneously.The handled fabric of this finishing agent, ABRASION RESISTANCE is good, and is soft, and water-proof air-moisture-permeable is desirable fabric finishing agent.Another characteristics of the present invention are to bake the processing fabric by padding, and technology is simple, and process does not have the hazardous solvent volatilization.Meet the green technology requirement fully.
Aqueous polyurethane grafted siloxane wear-resistant soft finishing agent of the present invention is to be solvent with water, is using solidification process not have the hazardous solvent volatilization.Can fundamentally eliminate the harmful substance in the coating.The environmental protection demand that meets the textile industry fabric.
