(5), then by said mixture it is cooled to 40 DEG C, adds triethylamine and acetone, stir 10-30 minute；
(6), while above-mentioned stirring, the deionized water of mixing urea is added；
(7), continuing stirring 60-120 minute, vacuum pumps acetone, i.e. can get finished product.
Described prepolymer isocyanate group content (NCO) content maintains 0-4.3%.
The index of Response of described NCO:OH is 1.0-1.3.
It is good that the super soft bottom coating resin processed for corium surface produced in aforementioned manners has flexibility, light resistance, water-tolerant, percentage elongation reaches 1000-1500%, has splendid submissive feel, chemical resistance with this resin processed corium, wear-resisting, there is high stretching, high elongation rate, water-fast moisture-proof, uvioresistant, non yellowing, Gao Guang；TPU, PU are removed from office by this resin, and PVC, PC, nylon cloth, Lycra, high-tension cloth adhesive force is good.
Detailed description of the invention
Below in conjunction with design parameter, the present invention will be described.
Its formula is calculated by mass percentage, 220 polyethers of 10-20%, 3010 polyethers of 5-15%, the polytetramethylene ether diol (PTMEG) of 10-30%, 10-40% isophorone diisocyanate (IPDI), 1.4 butanediols of 1-7%, dihydromethyl propionic acid (DMPA), the organic bismuth catalyst of 0.001-1%, 1-9% triethylamine, the carbamide of 1-10% and the appropriate deionized water of 3-13% are polymerized by acetone method.
Its concrete technology is as follows:
(1), first by 220 polyethers, 3010 polyethers, polytetramethylene ether diol (PTMEG) putting in reactor, be heated to 110-120 DEG C, then evacuation is dehydrated 30 minutes to 60 minutes；
(2), by said mixture cool to 85 DEG C, add organo-bismuth Cui's agent and stir 10 minutes；
(3) in said mixture, add isophorone diisocyanate (IPDI), again, maintain temperature 70-90 DEG C to be incubated 120-180 minute；
(4) in above-mentioned temperature compound, then add 1,4 butanediols, dihydromethyl propionic acid (DMPA) and appropriate acetone, the hydrophilic of aqueous polyurethane is had an impact by dihydromethyl propionic acid (DMPA), maintains temperature 70-90 DEG C to be incubated 180-240 minute and continues reaction；Sampling detection isocyanate group content (NCO) so that it is content maintains 0-4.3%；
(5), then by said mixture it is cooled to 40 DEG C, adds triethylamine and acetone, stir 10-30 minute；
(6), while above-mentioned high-speed stirred, the deionized water of mixing urea is added；Speed of agitator is one of key factor affecting dispersion effect, when rotating speed is too low, and the waterborne polyurethane resin storage instability obtained, along with the raising of rotating speed, the outward appearance of dispersion liquid takes a turn for the better, and emulsion mean diameter reduces, painting membrane stability improves, and mechanical performance and resistance to water also improve.Raise speed on product without impact further, but power consumption can be increased.
(7), continuing stirring 60-120 minute, vacuum pumps acetone, i.e. can get finished product.
Hardness and the resistance to water of waterborne polyurethane resin film are all had an impact by the ratio of NCO/OH, and along with the increase of the ratio of NCO/OH, hardness of film becomes big, and pliability, resistance to impact then decline after the ratio of NCO/OH reaches a degree.Along with the increase of the ratio of NCO/OH, intramolecular rigidity chain link such as amino-formate bond, urea bond content increase, and cohesive energy increases, and intramolecular forms stronger microfacies crosslinking, and therefore the resistance to water of film improves.Need the ratio considering NCO/OH on the hardness of waterborne polyurethane resin film and the impact of resistance to water, so the molar ratio of optimum N CO/OH of the employing of the present invention is 1.0-1.3.
