Abstract
The invention discloses a preparation method of anti-fuzzing and anti-pilling polyurethane finishing agents. The method comprises the following steps of: (1) adding organic solvents of N, N-dimethyformamide, methylene diphenyl diisocyanate (MDI) and hexamethylene diisocyanate (HDI) and a catalytic amount of dibutyltin dilaurate into a reaction kettle filled with inert gas, and heating and dissolving the materials; (2) mixing and dissolving the metered polyether polyol N330 and 1, 4-butanediol, slowing dripping the mixed solution into the reaction kettle, controlling the temperature to take reaction for 1 to 5 hours and obtaining prepolymerization products; and (3) sequentially carrying out end sealing and neutralization treatment on the prepolymerization products, reducing the pressure to remove solvents of N, N-dimethylformamide, and adding deionized water for preparing the materials into water agents with the solid content being 30 to 35 percent. The polyurethane finishing agents has the advantages of good cross linking performance, waterproof performance, anti-yellowing performance, storage stability, safety, no toxicity and the like, fabrics after the finishing has the advantage that the scrubbing washing resistance, static resistance and anti-fuzzing and anti-pilling properties are excellent.
Description
Technical field:
The present invention relates to a kind of preparation method of anti-fluffing and anti-pilling polyurethane finishing agent.
Background technology:
Wool, viscose, cotton textiles and BLENDED FABRIC thereof. particularly knitted fabric is in processing, dress and washing process, because the rubbing action between fabric or fabric and other object; Its surface can produce many fine hair; Electrostatic interaction in addition, fabric face can produce pilling, thereby causes appearance of fabrics and feel variation; Reduce with the contact skin comfort level, influenced the wearability of knitted fabric.Polyurethane arrangement can not only be given the fabric sofetening performance, fabric is had wet, multiple functions such as waterproof, shrinkproof, antistatic, ANTIPILLING, flexible and good luster.
Polyurethane 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 dispersions of polyurethanes system of decentralized medium, and main raw material is to contain urethano (NH one CO one) on the polyisocyanates macromolecular chain that reaction generates with polyol and urinate basic (NH one CO one NH one) construction unit.Employed raw material directly affects the final performance of product in synthetic, has high strength, rub resistance, and is nontoxic grade for excellent properties is being used widely aspect light textile, leather, coating, adhesive, the printing etc. a lot.But the fabric that common anti-fuzz balls polyurethane auxiliary agent obtains is anti-wash by rubbing with the hands with the anti-fluffing and anti-pilling performance not enough, lost efficacy easily.
Summary of the invention:
Goal of the invention:, the invention provides a kind of preparation method of anti-fluffing and anti-pilling polyurethane finishing 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 anti-fluffing and anti-pilling polyurethane finishing agent; May further comprise the steps: step 1; In being full of the agitated reactor of inert gas, add organic solvent N; Dinethylformamide, 4, the dibutyl tin laurate of 4 '-'-diphenylmethane diisocyanate MDI, hexamethylene diisocyanate HDI and catalytic amount is heated to 60 ℃ of dissolvings; Step 2, the PPG N330 and 1 with metering after the 4-butanediol is miscible, slowly is added drop-wise in the agitated reactor, at 80 ~ 95 ℃ of following temperature control reaction 1 ~ 5h, obtains prepolymer product; Step 3 adds saturated solution of sodium bisulfite in the prepolymer product that is obtained, continue to obtain the polyaminoester emulsion of end-blocking at 80 ~ 95 ℃ of following insulation reaction 1 ~ 3h; Step 4 adds the triethylamine neutralizer in agitated reactor, regulate pH=7 ~ 9; Step 5, decompression removes solvent N, dinethylformamide, adding deionized water, to be mixed with solid content be 30 ~ 35% aqua, can obtain product.
The mass ratio of said MDI and HDI is 1.0 ~ 3.0:1.
Said N330 and 1, the mass ratio of 4-butanediol are 1 ~ 100:1
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 anti-fluffing and anti-pilling polyurethane finishing agent; Has good bridging property; Resistance to water, yellowing resistance, storage stability; Advantages such as safety non-toxic, the fabric after arrangement is anti-to be washed by rubbing with the hands and anti-fluffing and anti-pilling performance excellence.
The specific 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 agitated reactor that is full of nitrogen or inert gas, add organic solvent N successively, dinethylformamide 100.0kg) and MDI (300.0kg), HDI (125.0kg), two laurate diisobutyl tin (1.55kg) of catalytic amount are heated to 60 ℃ of dissolvings under stirring; In agitated reactor, slowly drip PPG N330 (400.0kg) and 1,4-butanediol (25.0kg) mixed solution, the control temperature is dripped and is finished at 80 ~ 95 ℃; Insulation reaction 1 ~ 5h is warming up to 90 ~ 105 ℃ with reactant liquor, adds the saturated solution of sodium bisulfite of end-capping reagent (125.0kg), reaction 1 ~ 2h; Then reactant liquor is cooled to 80 ℃, adds the triethylamine neutralizer, reaction 1h makes PH=7.9; Obtain the polyurethane of end-blocking, decompression removes solvent N, dinethylformamide; Add deionized water, to be mixed with solid content be 30 ~ 35% aqua, and high-speed stirred is even, obtains aqueous product.
