preparation example Construction

[0045] The preparation method of water-based wood coating of the present invention may further comprise the steps:

[0046] mixing raw materials comprising a mixed resin composed of a waterborne hydroxyacrylic resin and a waterborne hydroxyurethane resin to form a mixed resin component;

[0047] And, the water, 70-100 parts of the silicone material and 100 parts of the mixed resin component are mixed according to parts by mass.

[0048] As for the order of adding the above mixing, there is no limitation, and it will not particularly impair the performance of the product of the present invention.

[0049] What is not mentioned above is applicable to the prior art.

Embodiment 1

[0051] Step 1, preparation of mixed resin components. First, mix the raw materials of the mixed resin component, that is, the mixed resin (composed of water-based hydroxyacrylic resin and water-based hydroxyurethane resin): filler: additive: water = 100: 1: 1: 10, take out the mixed resin and put it in the container. Disperse at 500r / min for 2-3 minutes, add wetting agent at 500r / min and disperse for 2-3 minutes. Add dispersant and defoamer at 500r / min to disperse for 2-3 minutes. Add filler, disperse at 1200r / min for 20 minutes, add thickener and disperse at 800r / min for 4 minutes, then adjust the speed to 300r / min and disperse for 4 minutes, then inspect the package after defoaming.

[0052] Step 2: Mix 10 parts of water, 70 parts of siloxane and 100 parts of the mixed resin component according to parts by mass.

Embodiment 2

[0054] Step 1, preparation of mixed resin components. First mix the raw materials of the mixed resin component, that is, the mixed resin (composed of water-based hydroxyacrylic resin and water-based hydroxyurethane resin): filler: additive: water = 100: 10: 3: 20, take out the mixed resin and put it in the container. Disperse at 500r / min for 2-3 minutes, add wetting agent at 500r / min and disperse for 2-3 minutes. Add dispersant and defoamer at 500r / min to disperse for 2-3 minutes. Add filler, disperse at 1200r / min for 20 minutes, add thickener and disperse at 800r / min for 4 minutes, then adjust the speed to 300r / min and disperse for 4 minutes, then inspect the package after defoaming.

[0055] Step 2: Mix 20 parts of water, 100 parts of siloxane and 100 parts of the mixed resin component according to parts by mass.

Abstract

The invention discloses a waterborne woodware coating and a preparation method thereof. The waterborne woodware coating comprises, by mass, water, 100 parts of mixed resin component and 70-100 parts of siloxane, and raw materials of the mixed resin component include mixed resin composed of waterborne hydroxyl acrylic resin and waterborne hydroxyl polyurethane resin. The waterborne woodware coating takes condensate formed by cross-linking the mixed resin composed of the waterborne hydroxyl acrylic resin and the waterborne hydroxyl polyurethane resin and the siloxane as a film. The film contains silica chain segment and has high hardness, high wear resistance, high transparency and high fullness. The water is used as a solvent, so that the waterborne woodware coating has low VOC (volatile organic compounds).

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to water-based wood coatings and a preparation method thereof. Background technique [0002] Water-based wood coatings are water-based paints that use water as a diluent. Water-based paints include water-soluble paints, water-diluted paints, and water-dispersible paints (latex paints). Water-soluble paints use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. [0003] At present, there are many related reports on water-based wood coatings. For example, Chinese patent CN106318049A discloses a kind of insect-proof water-based wood coating, which is composed of the following parts by weight: 20-25 parts of styrene-acrylic emulsion, 8-10 parts of insect repellent, 1-2 parts of dispersant, disinfectant 0.8-1...
