Problems solved by technology

[0002] With the continuous development of my country's coating industry, the application of coatings is becoming more and more extensive, but the flash point of traditional coatings is low, and there is a risk of flammability during transportation and use. In terms of strength and coating effect, volatile compounds are commonly used, which makes traditional coatings emit unpleasant odors during use, which not only causes environmental pollution, but also threatens human health.

preparation example Construction

[0043] The present invention also provides the preparation method of the high-flash-point deodorant coating described in the above technical solution, comprising the following steps:

[0044] adding dispersant, anti-settling agent, wetting agent, film-forming aid and drier to the solvent, and dispersing to obtain the first solution;

[0045] Mixing the alkyd resin and terpineol with the first solution, and dispersing to obtain an emulsion;

[0046] The anti-skinning agent, zinc oxide and titanium dioxide are mixed with the emulsion and dispersed to obtain a high-flash-point clean-odor paint.

[0047] In the present invention, the dispersing agent, anti-settling agent, wetting agent, film-forming aid and drier are dispersed in a solvent to obtain a first solution. In the present invention, it is preferable to add dispersant, anti-settling agent, wetting agent, film-forming aid and drier to the solvent, and disperse the obtained mixed solution to obtain the first solution. In ...

Embodiment 1

[0055] Add 0.5 part of drier Borchers Dry0411HS, 0.3 part of dispersant Triton XN-45S, 0.5 part of anti-settling agent BYK-410, 0.2 part of wetting agent triton X-405, 5 part of film-forming aid dipropylene glycol butyl ether and added 14 parts of In D40 solvent, after dispersing at 500r / min for 10min, the first solution was obtained;

[0056] 50 parts of 389-9 alkyd resin and 5 parts of ɑ-terpineol were added to the first solution, and after being dispersed at 1000r / min for 20min, an emulsion was obtained;

[0057] Add 0.2 part of anti-skinning agent butanone oxime, 7 parts of zinc oxide and 18 parts of titanium dioxide into the emulsion, and after dispersion at 1500r / min for 20min, the finished paint with high flash point and clean taste is obtained.

Embodiment 2

[0059] Mix 0.6 parts of drier Borchers Dry0411HS, 6 parts of D40 solvent oil and 7.5 parts of D60 solvent to obtain a mixed solvent;

[0060] Add 0.3 part of dispersant Triton XN-45S, 0.5 part of anti-settling agent BYK-410, 0.2 part of wetting agent triton X-405, 5.5 part of film-forming aid dipropylene glycol butyl ether into the mixed solvent, disperse at low speed at 600r / min After 10min, the first solution was obtained;

[0061] 0.2 part of anti-skinning agent butanone oxime, 52 parts of 389-9 alkyd resin, 6 parts of ɑ-terpineol were added to the first solution, and after high-speed dispersion at 1000r / min for 20min, an emulsion was obtained;

[0062] Add 8 parts of zinc oxide and 14 parts of titanium dioxide into the emulsion, and after high-speed dispersion at 1500r / min for 20min, the finished paint with high flash point and clean taste is obtained.

Abstract

The invention belongs to the technical field of coatings, and particularly relates to a high-flash-point odorless coating as well as a preparation method and application thereof. The invention provides a high-flash-point odorless coating. The high-flash-point odorless coating comprises the following components in parts by weight: 50-60 parts of alkyd resin; 10-20 parts of a solvent; 5-10 parts of zinc oxide; 10- 25 parts of titanium dioxide; 3- 5 parts of alpha-terpilenol; 4-5 parts of a coalescing agent; 0.3- 0.5 part of a dispersant; 0.4 - 0.6 part of an anti-settling agent; 0.1 - 0.3 part of a wetting agent; 0.5 - 0.7 part of a drier; and 0.1- 0.3 part of an anti-skinning agent. According to the invention, the high-flash-point compound is taken as a main body and is matched with the high-flash-point auxiliary agents; under the action of the zinc oxide, the titanium dioxide, the alpha-terpilenol, the dispersing agent, the anti-settling agent, the drier, the wetting agent and the anti-skinning agent, the flash point of the coating is increased, so that the flash point of the coating is maintained at 61 DEG C or above; and the coating provided by the invention has no special smell, and is green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a high-flash-point clean-odor coating and a preparation method and application thereof. Background technique [0002] With the continuous development of my country's coatings industry, the application of coatings has become more and more extensive, but traditional coatings have low flash points, and there is a risk of flammability during transportation and use. In terms of focus and coating effect, volatile compounds are often used, which makes traditional coatings emit an unpleasant odor during use, which not only causes environmental pollution, but also threatens human health. How to increase the flash point of the coating and reduce the odor of the coating on the premise of ensuring the dispersion, adhesion and coating effect of the coating is an urgent problem to be solved in the coating industry.
