Problems solved by technology

[0002] At present, in the process of wood transparent finishing, it is difficult for wood varnishes to fill the wooden holes well and keep the original wood texture clear and transparent as much as possible.
Generally, multi-layer coating is used, and then each sanding is used to fill the wooden holes to maintain transparency. The loss of the coating film is too large, the work efficiency is reduced, and it is not conducive to environmental protection.

Embodiment Construction

[0025] The invention adopts short-oil alkyd resin as base material, adds special high-quality transparent filler, and selects other additives, talcum powder and diluent to prepare. Described high transparency, high filling type environment-friendly polyurethane wood lacquer formula is composed as follows (by weight percentage):

[0026] 1) Short oil alkyd resin 55-80

[0027] 2) Thinner 5-23

[0028] 3) Dispersant 0.1-1.0

[0029] 4) Defoamer 0.1-0.5

[0030] 5) Anti-settling agent 0.1-1.0

[0031] 6) 1250 mesh talcum powder 0-15

[0032] 7) minspar7 / 10 transparent filler 5-15

[0033] 8) Zinc stearate 1-6

[0034] 9) Drier 0.01-1.0

[0035] 10) Leveling agent 0.1-1.0

[0036] The raw materials in the above formula are described as follows:

[0037] Among them, the short-oil alkyd resin such as Miki's 1170D is used; the diluent is a mixed organic solvent that can meet the requirements of polyurethane; the dispersant, defoamer, and leveling agent are respectively BYK-P...

Abstract

The invention relates to an environment-friendly paint, in particular to the paint which is used in carpentry transparent coating technique, can be used for protecting and decorating, has the advantages of high transparency and good filling property, improves the coating efficiency and reduces the loss of film coating. A preparation technique of the paint comprises the steps: first, short-oil alkyd resin, diluent, dispersing agent and antifoaming agent are sequentially added and evenly dispersed at intermediate speed; then, talcum powder, transparent filler and zinc stearate are added and dispersed at high speed to have the fineness of less than or equal to 50mu m; finally, the diluent, drier and leveling agent are added and evenly stirred at intermediate speed; after being detected to be qualified, the product is filtered and packed, so that the high transparency high-filled environment-friendly polyurethane carpentry paint is obtained.

Description

【Technical field】 [0001] The invention relates to a polyurethane wood varnish, in particular to an environment-friendly paint with high transparency and high filling property, which is used for protection and decoration in the transparent coating process of wood ware. 【Background technique】 [0002] At present, in the wood transparent finishing process, it is difficult for wood varnishes to fill the wood holes well and keep the original texture of the wood clear and transparent as much as possible. Generally, multi-layer coating is used, and then each layer of sanding is used to fill the wooden holes to maintain transparency. The loss of the coating film is too large, the work efficiency is reduced, and it is not conducive to environmental protection. 【Content of invention】 [0003] The invention aims at the transparent coating of woodware, and provides a high-transparency, high-filling environment-friendly polyurethane woodware paint. [0004] The present invention adopt...
