preparation example Construction

[0081] The preparation method of described varnish comprises the steps:

[0082] providing the components described in the composition above;

[0083] Stir and mix the modified short oil alkyd resin, special anti-scratch powder, additives for varnish and solvent, and disperse to obtain the varnish.

[0084] In one embodiment, pour 40-60% of the modified short-oil alkyd resin into the dispersion tank, add 1%-2% of the dispersant under the condition of constant rotation speed, and then slowly add the special anti-oxidant under low-speed stirring. Scoot 5-15%, then stir at high speed until the fineness is qualified, add 0.5-1% of anti-settling agent, 0.1-0.5% of defoamer, 0.1-0.5% of leveling agent, 1-5% of hand wax, and 15% of solvent ~ 20% and nitrocellulose 10 ~ 20%, high-speed stirring for 10 ~ 20 minutes to obtain the finished product.

[0085] The advantages of the present invention are:

[0086] The present invention aims to solve the problems of the prior art, and prov...

Embodiment 1

[0095] Pour 500g of 18 carbon castor oil modified Thor oleic acid short oil alkyd resin (purchased in Changxing Chemical Industry (China) Co., Ltd.) into the dispersing tank, slowly add 12g dispersing agent under the rotating speed of 1500rad / min, stir well Finally, the rotating speed drops to 1000rad / min, slowly add 100g 925 quartz powder (purchased from Sibelco (Shanghai) Mining Co., Ltd.) at this rotating speed, then increase the rotating speed to 2000rad / min, and maintain the rotating speed until the fineness is qualified Finally, add anti-settling agent (fumed silica) 8g, defoamer 2g (AFCONA2035), leveling agent (BYK 330) 2g, handle wax (BYK 988) 20g, solvent (PMA) 196g and nitrocellulose (purchased in Eternal Chemical Industry (China) Co., Ltd.) 160g, after high-speed stirring for 10-20min, the finished product was obtained.

[0096] After mixing the finished product and the polyurethane curing agent evenly in a ratio of 2:1, dilute it with a solvent (PMA or BAC or a mix...

Embodiment 1a

[0098] Example 1a is similar to Example 1, except that the defoamer is AFCONA 2045, the leveling agent BYK331, the handle wax BYK 998, and the solvent is BAC (butyl acetate).

Abstract

The invention provides a wood semigloss varnish composition which comprises the following raw materials in parts by weight: 40 to 60 parts of modified short oil alkyd resin, 5 to 15 parts of scuffing-resistance powder, 0 to 30 parts of assistant for varnish and 15 to 20 parts of solvent, wherein the modified short oil alkyd resin is short oil alkyd resin which is modified by castor oil and has oil length of 35 to 45; and the scuffing-resistance powder has Moh's hardness of not lower than 8 and the mesh number of not lower than 1,250 meshes.

Description

technical field [0001] The invention relates to an anti-scratch matt wood varnish composition, in particular to an anti-scratch matt wood varnish composition and a preparation method of the varnish. Background technique [0002] Due to the influence of various human factors during the use of traditional wood coatings, local scratches will inevitably occur, affecting the appearance of the coating and shortening the service life. At the same time, the matt paint, which has been gradually developed after the glossy paint, has become popular in the home decoration and fishing tackle industry quickly due to its soft visual effect and good touch. However, the existing matt paint has a fatal The weakness is that it is not scratch resistant. In people's daily life, various daily necessities are constantly rubbing against the surface of the paint film, and the scratches are turned into a bright paint film, and the consistency of the paint surface gloss is destroyed. Therefore, it is...
