Technical background
Before the present invention made, the brightening agent that is used for artificial leather material's top coat at present was a solvent borne polyurethane glue product.It mainly has the following disadvantages: contain a large amount of solvents big as toxicity such as toluene, dimethyl formamides, 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, wears no resistance, and is difficult to reach industrial requirement.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the preparation method of the high environment-friendly type wear-resisting weather-proof brightener used for artificial leather of a kind of bonding intensity is provided.
The present invention is a kind of environment protection type single-component aqueous polyurethane, is to be solvent with water, can fundamentally reduce and eliminate the objectionable impurities in the coating.The glossiness of the brightening agent that makes is 90-93, and tensile strength reaches 35-40Mpa.Make the wear-resisting corium that reaches of leatheroid light remove from office requirement.Characteristics of the present invention are the intensity height of this thermosol brightening agent, and are soft.Another characteristics of the present invention are not have the hazardous solvent volatilization in spraying and blade coating solidification process.Meet the requirement of leather green technology fully.
The object of the present invention is achieved like this: a kind of preparation method of environment-friendly type wear-resisting weather-proof brightener used for artificial leather, it is characterized in that: use vulcabond, methylol silicone oil and ester compound generate end group and be-performed polymer of NCO, use hydrophilic monomer then, coupling agent, the glycol ether chain extending reaction, regulate the pH value to neutrality with amine at last, add deionized water and stirring, concrete grammar is: add ester compound in reaction vessel, vulcabond, methylol silicone oil, reacted 1.5 ± 0.5 hours down at 85 ± 5 ℃, be cooled to 70-75 ℃, add dimethylol propionic acid (DMPA), glycol ether, insulated and stirred 30-40min, dropping accounts for the dibutyl tin dilaurate of vulcabond weight 0.08-0.12%, add coupling agent, add the acetone that accounts for brightening agent finished product gross weight 0.8-1.2% and reduce system viscosity, 60 ± 5 ℃ are incubated 4.5 ± 0.5 hours, reduce to room temperature, add the triethylamine neutralization, add deionized water, stir, slough acetone, promptly obtain environment-friendly type wear-resisting weather-proof brightener used for artificial leather, each material is to react according to following proportioning:
-NCO :-OH=3-4: 1, wherein-and NCO represents isocyanate group ,-OH represents the hydroxyl of ester compound,
The mol ratio of dimethylol propionic acid and ester compound is 0.5-1: 1,
The mol ratio of glycol ether and ester compound is 1.2-2: 1.
