The method comprises the following steps: taking IPDI, PEG1000, BDO and DMPA as raw materials to prepare prepolymer; adding an organosilicone coupling agent A-110 to modify the prepolymer; adding triethylamine to perform neutral reaction to generate salt; and adding the right amount of deionized water to obtain a waterborne polyurethane leather adhesive. According to the invention, the obtained waterborne polyurethane anti-pilling agent has the advantages of excellent anti-pilling performance, water resistance and environmental protection.
Description
Technical field
The present invention relates to the preparation method of a kind of aqueous polyurethane anti pilling agent, belong to chemical field.
Technical background
The processing such as pure cotton knitted fabric floats through over-cooking, dyeing, arrangement, its surface can produce many fine hair, in addition electrostatic interaction, wear for some time after, fabric face is understood pilling, affects attractive in appearance and comfort.Usually need to adopt the anti pilling agent to come so that the fabric face aesthetics is strong.Aqueous polyurethane is a kind of formaldehydeless resin finishing agent, can form tough film at fabric face, reduces the slippage of fiber, and fiber end is sticked on the yarn, and friction makes and is difficult for forming lint, thereby effectively improves the anti-pilling of fabric.But aqueous polyurethane is owing to the existence of a large amount of hydrophilic radicals, its poor water resistance.In addition since in traditional anti pilling agent because the existence of a large amount of acetone causes the VOC discharging to exceed standard, the feature of environmental protection is poor, therefore, studies a kind of anti pilling agent with excellent water resistance, anti-pilling, feature of environmental protection and has great importance.
Summary of the invention
The preparation method who the purpose of this invention is to provide the agent of a kind of aqueous polyurethane anti pilling, the aqueous polyurethane that obtains has excellent water resistance, anti-pilling, the feature of environmental protection.
For realizing above purpose, the preparation method of a kind of aqueous polyurethane anti pilling of the present invention agent, its step is specially:
(1) with isophorone diisocyanate (IPDI), polyoxyethylene glycol (PEG1000), 1,4-butyleneglycol (BDO), dimethylol propionic acid (DMPA) prepare performed polymer for raw material, 88 ℃ of stirrings, rotating speed is 1000r/min, reaction 2.5h looks viscosity and changes adding solvent N-first class pyrrolidone (NMP) in the process.
(2) add organo-silicon coupling agent A-110 modification performed polymer, reaction 45min.
(3) be cooled to 40 ℃, add triethylamine and carry out neutralization reaction generation salt, reaction 3-4min.
(4) add the entry strong stirring, rotating speed is 1800r/min, and emulsification 60min has obtained the agent of aqueous polyurethane anti pilling.
The proportioning of performed polymer raw material is in the step (1): the mol ratio of IPDI and PEG1000, BDO, DMPA is 1.3: 1-1.4: 1, BDO accounts for the 2%-3% of performed polymer quality, and DMPA accounts for the 6%-7% of performed polymer quality.
The consumption of NMP is can make stirring carry out smoothly in the step (1).
The consumption of A-110 is the 4%-5% of performed polymer quality in the step (2).
The amount of substance of triethylamine is identical with the amount of substance of DMPA in the step (3).
The consumption of the middle water of step (4) is 2 times of performed polymer total mass.
The beneficial effect that the present invention produces is, this patent adopts the organo-silicon coupling agent modified polyurethane prepolymer, the surface energy of silicoorganic compound is lower, have the excellent properties such as low temperature resistant, ageing-resistant, hydrophobic, organic solvent-resistant, radiation hardness, can also give coating outstanding snappiness and smooth Silk-like handle, after having added organo-silicon coupling agent, because polysiloxane is gathered in film coated surface, so that the film coated surface hydrophobicity increases, water molecules is difficult to infiltrate the inside of filming, make water be difficult for being combined with polyurethane molecular, thereby water-intake rate descend.Adopt chemical process that urethane and organosilicon are combined, advantage that can comprehensive two kinds of resins.In addition, this patent adopts NMP as solvent, and consumption is few, and volatility is little, greatly reduces the VOC quantity discharged, and the feature of environmental protection is strong.
