Abstract
The invention relates to a preparation method of poly-(epsilon-caprolactone) siloxane water-based polyurethane coating for woodenware. The coating which is mainly applied to the surfaces of woodenware and furniture is characterized in that: diisocyanate, alkyl hydroxy silicone oil and poly-(epsilon-caprolactone) are used to generate a preformed polymer with end group of -NCO, then hydrophilic monomer, coupling agent and diglycol are used to create a chain reaction, and at last deionized water is added for agitation after amine is used to neutralize a pH value and the environmental-friendly water-based polyurethane poly-(epsilon-caprolactone) siloxane coating is obtained. The coating has high strength and the paint film has no yellow stain. The invention has another characteristic that no harmful solvent volatiles during the process of spray coating, scratching and solidifying, thereby completely meeting the environmental protective technical requirements on coatings.
Description
Technical field
The present invention relates to the preparation method of a kind of woodenware with environmentally friendly polycaprolactone siloxane aqueous polyurethane paint.Described coating is mainly used in the top coat of woodenware, furniture.Belong to the chemistry painting industry technical field.
Background technology
Before the present invention made, being used for woodenware, furniture at present, to make the coating of top coat mainly be solvent-borne type polyester or polyurethane material.It mainly has the following disadvantages:
Than higher, and contain a large amount of solvents big as cost of manufacture, in use a large amount of solvent serious environment pollutions of its discharging as toxicity such as toluene, dimethyl formamides.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 attachment fastness of the aqueous polyurethane wood lacquer of general traditional method preparation is low, and intensity and weathering resistance are bad.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the preparation method of a kind of attachment fastness height, environmentally friendly polycaprolactone siloxane aqueous polyurethane paint for woodenware is provided.
The object of the present invention is achieved like this: a kind of preparation method of polycaprolactone siloxane aqueous polyurethane paint for woodenware, it is characterized in that: generate the performed polymer of end group for-NCO with vulcabond, alkane hydroxy silicon oil and polycaprolactone, then with hydrophilic monomer, adding coupling agent, glycol ether chain extending reaction, regulate the pH value to neutrality with amine at last, add deionized water and stirring, concrete grammar is:
In reaction vessel, add polycaprolactone, vulcabond and alkane hydroxy silicon oil, reacted 1.5 ± 0.5 hours down at 85 ± 5 ℃, be cooled to 70-75 ℃, add dimethylol propionic acid (DMPA), one 27 glycol that contract, insulated and stirred 30-40min, dropping accounts for the dibutyl tin dilaurate of vulcabond weight 0.08-0.12%, coupling agent, add the acetone that accounts for polyurethane coating finished product gross weight 0.8-1.2% and reduce system viscosity, 60 ± 5 ℃ of insulations 4.5 ± 0.5 hours, reduce to room temperature, add the triethylamine neutralization, add deionized water, stir, slough acetone, promptly obtain woodenware environment-friendly type aqueous polyurethane polycaprolactone siloxane coating, each material is to react according to following proportioning:
-NCO :-OH=3-4: 1 mol ratio, wherein-NCO represent isocyanate group ,-OH represents the hydroxyl of polycaprolactone,
The mol ratio of dimethylol propionic acid and polycaprolactone is 0.5-1: 1,
The mol ratio of glycol ether and polycaprolactone is 1.2-2: 1.
Described coupling agent is an organo-silicon coupling agent.As KH550 or KH560.
Described vulcabond can be IPDI, HDI, TDI or MDI, preferred TDI or IPDI.
Described alkane hydroxy silicon oil molecular weight is 1000-3000.
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 glossiness of the coating that makes is 90-93, and tensile strength reaches 35-40Mpa.Characteristics of the present invention are the dry film intensity height of this coating, and are soft, not xanthochromia.Another characteristics of the present invention are not have the hazardous solvent volatilization in spraying and blade coating solidification process.Meet the requirement of coating green technology fully.
