Abstract
The present invention relates to a kind of polyurethane binder, it is by polyisocyanates, polyol, and aliphatic diol class and additive are dissolved in the organic solvent, react to form under the effect of catalyzer.Have the cohesive strength height, anti-solvent, hydrolysis, vibration resistance, shock resistance, advantage such as wear-resisting is applicable to the tackiness agent that uses in the tackiness agent of making static flocking on the PVC leather surface and weaving, clothes and the shoemaking industry.
Description
The present invention relates to a kind of flocking adhesive, particularly polyurethane binder.
The domestic flocking adhesive of listing in the Chemicals handbook has only one kind of EX-1 at present, and this is a kind of emulsion of being made up of the self-cross linking type acrylic acid or the like.In addition, exclude the ZR-961 of handbook in addition, two kinds of acrylic adhesives of ZR-829.They are only applicable to viscose fibre fine hair in cotton or blended fabric substrate.
The object of the present invention is to provide a kind of viscose fibre fine hair in cotton or blended fabric substrate that is not only applicable to, and can be on the PVC leather surface polyurethane binder of viscose fibre fine hair.
Polyurethane binder provided by the present invention is by polyisocyanates, and polyol, fat spin family's glycols and additive is dissolved in the organic solvent, reacts to form under catalyst action.The polyisocyanates that uses has TD1, MD1, and PAP1 etc., and TD1 divides 2.4-TD1 and two kinds of isomer of 2.6-TD1.The polyol that uses has polyester resin, polyether resin, Viscotrol C, Resins, epoxy etc.The aliphatic diol class of using has the 1.3-butyleneglycol, 1.4-butyleneglycol, propylene glycol, ethylene glycol etc.The organic solvent that uses has the ester class, ketone and aromatic hydrocarbon, and halohydrocarbon etc. are generally selected the organic solvent of boiling point between 55 °-80 ℃ for use.The catalyzer that uses has tertiary amines, organometallic compound and organophosphorus etc.The add-on of producing the various compositions of per kilogram polyurethane binder is: polyisocyanates 0.090-0.100kg, polyol 0.550-0.560kg, aliphatic diol class 0.002-0.003kg, additive 0.002-0.003kg, organic solvent 0.340-0.350kg, catalyzer 0.001-0.003kg.With the polyisocyanates of selecting for use, polyol, the aliphatic diol class, additive, organic solvent and catalyzer are added in the reactor according to a certain percentage, and temperature of reaction is controlled at 50 °-85 ℃, and be 12 hours reaction time.After reaction finishes, adjust quality and filter taking-up, the said polyurethane binder of the present invention that Here it is, its chemical equation is:
When polyurethane binder of the present invention is applied on the fabric static flocking, can use separately, also can use with other materials blendings.But static flocking need adopt the tackiness agent of two-pack on the PVC leather surface, the isocyanic ester that promptly in polyurethane binder of the present invention, adds modification, its allotment ratio is: 100 parts of polyurethane binder, and isocyanic ester 5-12 part of modification, allotment earlier stirs before using.This polyurethane binder since molecular chain in contain isocyano-(NCO) and carbamate groups (NH-CO-O-), show the activity and the polarity of height, have very high adhesive property for synthon hair static flocking and various material on the PVC leather surface.Can form the hydrogen chain between the macromolecular chain simultaneously, make its cohesive strength height, anti-solvent, wear-resisting, adopted special polyester polyol in addition, anti-hydrolytic performance is also better.The isocyanic ester of polymer modification has the molecular linkage of flexibility, thereby very high elasticity is arranged, vibration resistance, and shock resistance, antifatigue, particularly resistance to low temperature is fabulous, is better than other any tackiness agents.This tackiness agent is not only applicable to static flocking, also be applicable to weaving, clothes and shoemaking industry, and fabric and polyurethane imitation cortex close, polyurethane foam is laminated, the frlml laminating of packing and electric insulation, adhering to polyurethane foams is scrubbed pad, is specially adapted to require the jacquard weave flocking of clear skeletal lines.
Embodiment:
Suppose to produce one kilogram of polyurethane binder.Select 0.57 mole of tolylene diisocyanate in the polyisocyanates for use, 0.45 mole of polyester polyol in player's polyol, select ethylene glycol and TriMethylolPropane(TMP) 6-7 gram in the aliphatic diol class for use, select toluene and 1: 0.9 mixed solvent of butanone, 345 grams in the organic solvent for use, select organometallic compound 2 grams in the catalyzer for use.Earlier polyester polyol is put into there-necked flask, be warmed up to 115 ℃, start agitator and dewatered 20 minutes, be cooled to 80 °-90 ℃, add TriMethylolPropane(TMP) and ethylene glycol, stirred 10 minutes, it is dissolved in the polyester, cool the temperature to 60 °-40 ℃ again and keep constant temperature.1/3 of the mixed solvent total amount of toluene and butanone is added in the bottle, after stirring, drip tolylene diisocyanate, react after one hour, add catalyzer, again according to the viscosity of ever-increasing resultant of reaction, add remaining mixed solvent in the flask in installments meticulously, the viscosity of resultant is remained between the 70000-100000CPS, about isothermal reaction 12 hours, add additive 2 grams, stirring to go out still, promptly obtains polyurethane binder of the present invention through 50-100 order nylon net filter.
