Problems solved by technology

The products mainly include polyurethane dispersion type and water-based acrylic emulsion type. Although the construction of general paint is simple and the cost is low, it has a strong smell and has not volatilized its own smell for a long time after construction, let alone absorbing the smell of other substances. For environmental performance, it is necessary to develop a high-performance water-based paint that can absorb a variety of harmful VOCs indoors

Embodiment Construction

[0009] 1. Main paint

[0010] 1.11 Benzene-free environmental protection resin

[0011] The present invention selects NOVALKYD 3801 (DS Company) which has good brushing properties, good yellowing resistance, fast drying speed, high hardness and does not contain benzene solvents, and its consumption is 48% of the total weight of the main paint.

[0012] 1.12 Defoamer

[0013] Defoamers are used in solvent-borne coating systems to prevent foam and foam formation during coating production, packaging and application. The amount of defoamer added must be determined through experiments. If the amount added is too small, the desired defoaming effect will not be achieved; if too much, it will cause morbid conditions such as shrinkage of the paint film and poor recoatability. You can choose BYK series defoamer, the dosage is about 0.1-0.3%. Select BYK-066N, its dosage is 0.2% of the total weight of the main paint.

Abstract

The invention discloses a Chinese yew polyurethane paint, which is composed of main paint, curing agent, and diluent according to a weight ratio of 1:0.5:0.4. The main paint is composed of following components in percentage by the total weight of the main paint: 48% of benzene-free environment-friendly resin, 0.1% to 0.3% of antifoaming agent, 0.8% of thickening agent, 0.1% of surface rheological agent, 0.4% of moisture dispersant, 6% of digestant, 20% of pigment, 10% of stuffing materials, 11.5% of solvent, and 3% of paclitaxel factors extracted from Chinese yews. The curing agent is composed of 40% of isocyanate matter and 60% of auxiliary agent. The diluent is composed of butyl acetate and propylene glycol monomethyl ether propionate according to a weight ratio of 3:1.

Description

technical field [0001] The invention relates to a paint, in particular to a yew polyurethane paint. Background technique [0002] Indoor decoration requires a lot of paint. At present, ordinary oil-based paint or water-based paint is generally used on the market, and it does not have the performance of absorbing harmful substances. The products mainly include polyurethane dispersion type and water-based acrylic emulsion type. Although the construction of general paint is simple and the cost is low, it has a strong smell and has not volatilized its own smell for a long time after construction, let alone absorbing the smell of other substances. For environmental performance, it is necessary to develop a high-performance water-based paint that can absorb a variety of harmful VOCs indoors. It is close to the effect of putting plants indoors to purify the air. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention...
