Problems solved by technology

[0002] With the deepening of people's understanding of coating products, more and more attention is paid to the taste and environmental protection requirements of ordinary PU matt varnishes, and most ordinary PU matt varnishes have low solid content, and it takes multiple coatings to achieve the film. Thickness requirements, a large amount of organic volatiles and free isocyanate volatilize into the atmosphere during painting, seriously polluting the atmospheric environment, and an unpleasant smell will be emitted after the coating is completely formed, which is harmful to the health of personnel

Embodiment Construction

[0047] The present invention will be further described in detail below in conjunction with specific embodiments:

[0048] a. Preparation of anti-settling polyamide wax (100Kg each time):

[0049] Weigh 15Kg of 6900-20X, 85Kg of xylene according to the ratio, then mix and disperse it evenly until the fineness is less than or equal to 15μm to obtain the polyamide wax anti-settling slurry;

[0050] b. Preparation of component A:

[0051] Weigh each raw material component of component A according to the percentage content of the example in Table 1 below, and sequentially combine the net taste alkyd resin, wetting and dispersing agent, defoaming agent, leveling agent, polyamide wax anti-settling, and propylene glycol After the ether acetate is uniformly dispersed at low speed, put the dumb powder into the dispersion tank, and then disperse at a high speed for 10-15 minutes until the fineness is ≤30μm, and then adjust the viscosity to 2000-2500mpa.s / 25℃ with n-butyl acetate to obtain Compo...

Abstract

The invention discloses PU matte finishing varnish and a preparation method thereof. The finishing varnish is prepared from a component A and a component B stored separately, wherein the component A contains net-flavor alkyd resin, propylene glycol methyl ether acetate and polyamide wax anti-settling pulp, the component B consists of an HDI curing agent, a TDI curing agent, an addition product curing agent and dehydrated n-butyl acetate; when the PU matte finishing varnish is used, the component A and the component B are mixed according to a weight ratio and then are diluted, and the weight ratio of the component A to the component B to a component C for dilution is 1:0.5:(0.5 to 0.7). A product is even in paint film gloss, strong in adhesive force, good in transparency and good in chemical resistance; during construction, good levelling and easy spraying are realized, and especially, a coating is weak in taste and environment-friendly.

Description

【Technical Field】 [0001] The invention relates to a PU matt clear finish paint and a preparation method thereof, and belongs to the technical field of wood coating manufacturing. 【Background technique】 [0002] With the deepening of people’s understanding of coating products, more and more attention has been paid to the taste and environmental protection requirements of ordinary PU matte varnishes, and most ordinary PU matte varnish films have low solids and require multiple coatings to achieve the film Thick requirements, a large amount of organic volatiles and free isocyanate volatilize into the atmosphere during painting, which seriously pollutes the atmospheric environment. After the painting is completely filmed, it will emit an unpleasant smell, which is harmful to the health of personnel. Responding to the national call for energy conservation and emission reduction, reducing VOC emissions and reducing the smell of coating films are the future development trends of wood co...
