Abstract
The invention discloses a preparation method of a waterborne polyurethane wool anti-felting treatment agent. The method comprises the following steps of: (1) adding methyl isobutyl ketone, MDI (Diphenyl-Methane-Diisocyanate), IPDI (Isophorone Diisocyanate) and a catalytic amount of dibutyltion dilaurate into a reaction kettle filled with inert gas, heating with stirring and dissolving; (2) dropwise adding polyether polyol PEG-800 and dihydroxy trimethylacetic acid, and reacting at controlled temperature for 1-5 hours to obtain a pre-polymerized product; (3) adding a saturated sodium bisulfite solution serving as an end-capping reagent into the obtained pre-polymerized product, and reacting for 1-2 hours; and (4) adding triethylamine serving as a neutralizing agent for regulating the pH to 7-9 to obtain end-capped polyurethane, removing methyl isobutyl ketone serving as a solvent under reduced pressure, and adding deionized water to prepare aqua of which the solid content is 30-35 percent. The treatment agent obtained in the invention has the advantages of high crosslinking property, water resistance, storage stability, nontoxicity and the like; and wool which is subjected to anti-felting treatment is resistant to washing, and has high anti-felting performance and plump handfeel.
Description
Technical field:
The present invention relates to a kind of aqueous polyurethane wool anti-felting finish agent, particularly a kind of preparation method of aqueous polyurethane wool anti-felting finish agent.
Background technology:
Wool has many good characteristics, like good springiness, water absorbability is strong, heat retention good, gloss is soft etc.Wool fabric is liked by the human consumer deeply with its noble style, superior wear behavior.Yet felting (Felting) through constantly pushing, rub down, can take place in untrimmed wool fabric when washing.Thereby cause cosmetic variation such as fabric size is dwindled, face is scared, weavy grain confusion, so that wool fabric in the process of taking, can only be hand-washed or dry-cleaning by low temperature, can not adopt violent washings such as washing machine, this washing for fabric is nursed and is caused very burden.In order to address this problem; Wool manufacturing worker in various countries' is devoted to the research of preventing felting and shrinking of wood fabric always, and through the many decades development, oneself obtains widespread use by warp wool anti-felting finishing; Formed the sophisticated technology of many covers, anti-machine washing function has become a kind of standard of high retaining wool product performance.To woolen antifelting treatment, still there is not one both not have Organohalogen compounds (AOX) pollution so far, do not damage wool quality again, and can possess the preventing felting and shrinking of wood fabric agent of over-all propertieies such as good hand simultaneously.
Urethane is the general name that has a family macromolecule material of carbamate groups on the main chain; Aqueous polyurethane is meant with water to be the polyurethane dispersions system of dispersion medium, and main raw material is to contain urethano (NH one CO one) on the POLYMETHYLENE POLYPHENYLISOCYANATE macromolecular chain that reaction generates with polyol and urinate basic (NH one CO one NH one) structural unit.Employed raw material directly affects the final performance of product in synthetic, has HS, rub resistance, and is nontoxic grade for excellent properties is being used widely aspect light textile, leather, coating, tackiness agent, the printing etc. a lot.
Summary of the invention:
Goal of the invention:, the invention provides a kind of preparation method of aqueous polyurethane wool anti-felting finish agent to the defective that prior art exists.
Technical scheme: for realizing the foregoing invention purpose, the present invention adopts following technical scheme:
A kind of preparation method of aqueous polyurethane wool anti-felting finish agent; May further comprise the steps: (1) adds the dibutyl tin laurate of organic solvent MIBK, '-diphenylmethane diisocyanate MDI, isophorone diisocyanate IPDI and catalytic amount in being full of the reaction kettle of rare gas element, and it is for use as A liquid to be heated to 60 ℃ of dissolvings under stirring; (2) in A liquid, drip, obtain prepolymer product in 80 ~ 95 ℃ of following temperature control reaction 1 ~ 5h by polyether glycol PEG-800 and dihydroxyl trimethylacetic acid liquid mixture prepared; (3) in the prepolymer product that obtains, add the saturated sodium sulfite solution of end-capping reagent, reaction 1 ~ 2h; (4) add the neutralizing agent triethylamine, regulate pH=7 ~ 9, obtain end capped urethane; (5) decompression removes the solvent MIBK, and adding deionized water, to be mixed with solid content be 30 ~ 35% aqua, can obtain product.
The mass ratio of said MDI and IPDI is 1.0 ~ 3.0:1
According to above technical scheme, can realize following beneficial effect: compared with prior art, the present invention has the following advantages: the present invention obtains the aqueous polyurethane wool anti-felting finish agent; Has good bridging property, water tolerance, stability in storage; Advantage such as nontoxic; Wool after antifelting treatment is anti-to be washed by rubbing with the hands, and shrinkproof performance is good, good hand feeling.
Embodiment:
Below in conjunction with embodiment the present invention is done detailed description further, but the scope that the present invention requires to protect is not limited to the scope that embodiment representes.
Embodiment 1:
In the reaction kettle that is full of nitrogen or rare gas element, add organic solvent MIBK (85.0kg) and MDI (254.0kg) successively, IPDI (100.0kg), two LAURIC ACID 99 MIN diisobutyl tin (1.25kg) of catalytic amount are heated to 60 ℃ of dissolvings under stirring; In reaction kettle, drip polyether glycol PEG-800 (335.0kg) and dihydroxyl trimethylacetic acid (12.5kg), controlled temperature drips and finishes at 80 ~ 95 ℃; Insulation reaction 1 ~ 5h is warming up to 90 ~ 105 ℃ with reaction solution, adds the saturated sodium sulfite solution of end-capping reagent (112.0kg); Reaction 1 ~ 2h then is cooled to 80 ℃ with reaction solution, adds the triethylamine neutralizing agent; Make PH=7.2, obtain end capped urethane, decompression removes the solvent MIBK; Add deionized water, to be mixed with solid content be 30 ~ 35% aqua, and high-speed stirring is even, obtains aqueous product.
