Problems solved by technology

Conventional cracked paint is usually sprayed on the nitro-based primer. Due to the high shrinkage rate of the cracked paint, it is easy to pull up the primer or the cracked paint itself falls off.
[0005] 2. Crackle paint produces cracks of different sizes and uneven patterns
As a result, cracks of different sizes are produced, and the pattern is uneven, which affects the appearance
[0006] 3. Poor matching

Embodiment 1

[0046] According to the weight percentage in Table 1.1, add 8% 1 / 2 second nitrocellulose, add 10% polyketone resin.

[0047] Then add ethyl acetate, butyl acetate, n-butanol in turn, soak for 8 hours, and disperse at low speed for 20-30 minutes to make it completely dissolve; stop adding epoxy soybean oil and hyperbranched silicone modified alkyd resin, and disperse at low speed for 10- 15 minutes; in low-speed dispersion, add fumed silica, titanium dioxide, and silicon micropowder respectively, and then disperse at high speed for 20-30 minutes to make the dispersion fineness ≤ 30um, and then the crack paint main agent can be prepared.

[0048] According to the weight percentage in Table 1.2, add ethyl acetate, butyl acetate, n-butanol in turn, divide at a low speed

[0049] Disperse for 10-15 minutes to get crack paint thinner.

[0050] figure 1 It is the main agent of crack paint

Abstract

The invention relates to a light-smell self-volatilizing white crackle paint coating and a preparation method thereof, and in particular, relates to a preparation method of a low-smell coating capableof generating cracks on any primer. The method is mainly realized by adopting the following technical formula and process. 5% of hyperbranched organic silicon modified alkyd resin, 8% of 1 / 2 second digested cotton, 10% of polyketone resin, 3% of epoxidized soybean oil, 13% of fumed silica, 3% of magnesium silicate and 10% of titanium dioxide are adopted and finally a butyl acetate solvent is added. The crackle paint prepared by the method has the advantages that no matter the crackle paint is sprayed or brushed on any base material, a regular crackle effect can be generated; the product is free of triphenyl and DOP addition, and is environment-friendly and healthy. The invention also discloses the preparation method of the crackle paint.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a clear-flavored self-volatile white cracked paint coating and a preparation method thereof. Background technique [0002] Crackle paint products are developing rapidly in the decoration market because of their beautiful patterns and three-dimensional effect. They are generally used in TV cabinets, TV background walls, and hotel door frames. Most of them are used as high-end decoration materials. Crackle paint is self-volatile paint, does not contain toxic ingredients such as triphenylformaldehyde and heavy metals, and has no irritating odor. It can replace paint for home hotel decoration. [0003] However, there are still several technical problems in domestic crack paint products: [0004] 1. Poor adhesion, easy to fall off. Conventional cracked paint is generally sprayed on a nitro-based primer. Due to the high shrinkage rate of the cracked paint, it is easy to pull up the primer or ...
