Abstract
The invention relates to waterborne polyurethane thermosol for coating used for artificial leather of bags and a preparation method thereof. The polyurethane thermosol for coating made by the method is mainly used for bonding of fabric and synthesized artificial leather, characterized in that Diisocyanate and ester compound can be mixed to make prepolymer, the terminal group of which is -NCO, and then hydrophilic monomer and 1,4-butanediol are added to do chain extending reaction. In the end after amine being used for adjusting the pH value to neutrality, deionized water is added and stirred. The waterborne polyurethane thermosol for coating is obtained. The adhesion strength of the thermosol is higher than that of solvent type PU adhesive. The thermosol can stand strong intensity. The bonding fabric is soft. The rigidity is in accordance with the technical demands for various artificial leather of bags and the performance. The invention has another characteristic, which is no volatilization of poisonous solvent when the invention is sprayed, scraped and solidified, and completely accords with the environmental and technical demands for chemical addition.
Description
Technical field
The present invention relates to the preparation method of a kind of case-bag artificial leather with the environment-friendly type aqueous polyurethane hot coating sol.This hot coating sol is mainly used in the bonding of textile fabric and artificial leather material.Belong to the auxiliary chemicals technical field.
Background technology
Before the present invention made, the hot coating sol that is used for case-bag artificial leather at present was a solvent-borne type PU glue.It mainly has the following disadvantages: than higher, and contain a large amount of solvents big as toxicity such as toluene, dimethyl formamides as cost of manufacture, in use a large amount of solvent serious environment pollutions of its discharging.Along with the more and more concern of countries in the world to environmental requirement, the increasingly stringent of environmental regulation, the solvent based product of high pollution is substituted by the watersoluble cleaning product gradually.
And the aqueous polyurethane bonding intensity of general traditional method preparation is low, and the thermosol of commercial aqueous polyurethane is seldom arranged.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the preparation method of a kind of case-bag artificial leather of replace solvents type polyurethane material with the environment-friendly type aqueous polyurethane hot coating sol is provided.
The object of the present invention is achieved like this: a kind of case-bag artificial leather use polyurethane hot coating sol and preparation method thereof, it is characterized in that: generate the performed polymer of end group for-NCO with vulcabond and ester compound, use hydrophilic monomer then, 1, the reaction of 4 chain expansion of succinic acid, regulate the pH value to neutrality with amine at last, adding deionized water and stirring gets final product, concrete grammar is: add ester compound in reaction vessel, vulcabond, 85 ± 5 ℃ of reactions 1.5 ± 0.5 hours, be cooled to 70-75 ℃, add dimethylol propionic acid (DMPA), 1,4 butyleneglycols, insulated and stirred 30-40min, dropping accounts for the dibutyl tin dilaurate of vulcabond weight 0.08-0.12%, add the acetone that accounts for coating adhesive finished product gross weight 0.8-1.2% and reduce system viscosity, be incubated 4.5 ± 0.5 hours, reduce to room temperature, add the triethylamine neutralization, add deionized water, stir, slough acetone, promptly obtain case-bag artificial leather environment-friendly type aqueous polyurethane hot coating sol, each material is to react according to following proportioning:
-NCO :-OH=2-3: 1 (mol ratio), wherein-NCO represents isocyanate group.
The mol ratio of dimethylol propionic acid and ester compound is 0.5-1: 1.
1, the mol ratio of 4 butyleneglycols and ester compound is 1-1.8: 1.
Described vulcabond can be IPDI, HDI, TDI or MDI.
Described ester compound can be poly adipate succinic acid ester or polycaprolactone.
The present invention is a kind of environment protection type single-component aqueous polyurethane, is to be solvent with water, can fundamentally eliminate the objectionable impurities in the coating.The number-average molecular weight of the thermosol that makes is 30000-50000 (gel chromatograph of waters company detects), and viscosity is 1500-2000cps (detection of Emila viscometer).Characteristics of the present invention are that the bonding intensity of this thermosol is big, the intensity height, and the feel of bonding fabric is stiffening.Another characteristics of the present invention are not have the hazardous solvent volatilization in spraying and blade coating solidification process.Meet the chemical industry environmental protection technical requirements fully.
