Problems solved by technology

[0003] Polyurethane paint, also known as polyurethane paint, can be divided into: acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, epoxy polyurethane, etc. according to the different components containing hydroxyl groups. In the furniture coating industry, Existing PU transparent primers are prone to prickly heat when one-time thick coating in high-temperature environments, and the primer must be painted many times to meet the requirements, resulting in low painting production efficiency

preparation example Construction

[0049] like figure 1 As shown, in one embodiment, the preparation method of the described PU high-definition transparent primer in the above-mentioned embodiment is provided, a kind of preparation method of PU high-definition transparent primer, comprising:

[0050] Step 101. Mix 70 to 80 parts of alkyd resin, 5 to 10 parts of butyl ester, 5 to 10 parts of propylene glycol methyl ether acetate, and 10 to 20 parts of filling powder, mix and stir evenly, and store in a sealed container , to obtain the main agent components.

[0051] Specifically, 70 to 80 parts of alkyd resin, 5 to 10 parts of butyl ester, 5 to 10 parts of propylene glycol methyl ether acetate and 10 to 20 parts of filler powder are mixed and stirred evenly, It is sealed and stored. When preparing the main ingredients, use a planetary mixer, under the conditions of a vacuum degree of -0.04 to -0.10MPa and a rotation speed of 30 to 40r / min, 70 to 80 parts of alkyd resin, 5 parts to 10 parts of butyl ester, 5 pa...

Embodiment 1

[0056] Mix 70 parts of alkyd resin, 5 parts of butyl ester, 5 parts of propylene glycol methyl ether acetate and 10 parts of filling powder, mix and stir evenly, seal and store to prepare the main ingredient components; mix 25 parts of butyl ester, 45 parts of Parts of L-75 and 15 parts of the trimer are mixed and stirred evenly, sealed and stored to obtain the curing agent component; the main agent component and the curing agent component are mixed according to a volume ratio of 1:0.7 to prepare The PU HD clear primer.

[0057] The PU high-definition transparent primer prepared in this example has good melting and dispersing of the system as a whole, has a fast drying rate, and the coating of the PU high-definition transparent primer has strong adhesion, good fullness and hardness. High, good abrasiveness, and one-time thick coating at high temperature will not cause prickly heat.

Embodiment 2

[0059] Mix 75 parts alkyd resin, 7 parts butyl ester, 7 parts propylene glycol methyl ether acetate, 15 parts filler powder, 0.2 part wetting agent, 0.2 part defoamer and 0.2 part leveling agent Stir evenly, seal and store to prepare the main agent components; mix and stir 30 parts of butyl ester, 50 parts of L-75 and 17 parts of trimer evenly, seal and store to prepare the curing agent components; the main agent The components and the curing agent components are mixed according to a volume ratio of 1:0.8 to obtain the PU high-definition transparent primer.

[0060] The PU high-definition transparent primer prepared in this example has good melting and dispersing of the system as a whole, has a fast drying rate, and the coating of the PU high-definition transparent primer has strong adhesion, good fullness and hardness. High, good abrasiveness, and one-time thick coating at high temperature will not cause prickly heat.

[0061] Compared with Example 1, 0.2 part of wetting age...

Abstract

The invention relates to a PU high-definition transparent primer and a preparation method thereof. A main agent component and a curing agent component are mixed according to a certain ratio to preparethe PU high-definition transparent primer body; the PU high-definition transparent primer has the advantages that the whole system is good in melting dispersion, the curing agent component can harmonize the flexibility of the system and has a high drying rate, and detection and trial prove that the PU high-definition transparent primer is high in coating adhesion, good in fullness, high in hardness, good in abrasiveness, free of prickly heat during high-temperature one-time thick coating and quite suitable for coating of wooden products.

Description

technical field [0001] The invention relates to the technical field of polyurethane primers, in particular to a PU high-definition transparent primer and a preparation method thereof. Background technique [0002] Wood lacquer refers to a type of resin paint used on wood products, including polyester, polyurethane paint, etc., which can be divided into water-based and oil-based, and can also be divided into high-gloss, semi-matte and matte according to gloss, and can be divided according to use. For furniture paint, floor paint and so on. Among them, polyurethane paint is widely used in wood furniture and wood floors due to its strong paint film, full luster, strong adhesion, water resistance and corrosion resistance. [0003] Polyurethane paint is also called polyurethane paint. According to the different hydroxyl-containing components, it can be divided into: acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, epoxy polyurethane, etc....
