Problems solved by technology

[0002] The wood paint on the surface of office furniture must have good boiling water resistance and cigarette butt scalding resistance. At present, the commonly used wood paint on the surface of office furniture is an oily system room temperature drying type coating. Ironing performance is poor
At the same time, oil-based wood lacquers are being gradually replaced by water-based wood varnishes due to serious pollution and non-environmental protection. Their development is limited. Can not be used in high-end office furniture

Embodiment 1

[0066] Get each component by the weight shown in embodiment 1 in table 1, and preparation method is according to the following steps:

[0067] Specific implementation steps:

[0068] Component A:

[0069] Step 1: adding high hydroxyacrylic acid dispersion resin into the paint mixing container;

[0070] Step two nano-silica sol surface treatment:

[0071] Add 20% deionized water in the formula to a container, slowly add 30% methyltrimethylolsilane in the formula under low-speed stirring at 400-500rpm, slowly add nano-silica sol, and then high-speed at 1000-1200rpm Disperse for 15 minutes to obtain the nano-silica sol surface treatment solution, and after standing for 60 minutes, slowly add the nano-silica sol surface treatment solution to the paint mixing container with the dispersion in step 1 under 400-500rpm low-speed stirring, and use 1000- Disperse at a high speed of 1200rpm for 30 minutes.

[0072] Step 3 Slowly add defoamer, wetting agent, leveling agent, and pH regu...

Embodiment 2

[0082] Take each component according to the weight of each component shown in Example 2 in Table 1, and repeat the method described in Example 1 to obtain component A and component B in Example 2;

[0083] According to component A: component B: water = 100:15:15, after mixing evenly, let it stand for ten minutes to defoam, the appearance of the obtained water-based two-component inorganic modified heat-resistant wood paint is: translucent, slightly white paint liquid , sprayed on the substrate plate that has been primed, wet film spraying amount: 90g / m 2 , Drying method: Surface drying of the paint film at room temperature for 35 minutes, hard drying time of 24 hours, and the comprehensive properties of the paint film measured after drying at room temperature for 7 days are shown in Table 2.

Embodiment 3

[0085] Take each component according to the weight of each component shown in Example 3 in Table 1, and repeat the method described in Example 1 to obtain component A and component B in Example 3;

Abstract

The invention discloses a water-borne bicomponent inorganic modified heat-resistant wood paint and a preparation method and a use method thereof. The wood paint is prepared by mixing the following components in parts by weight: a component A comprising 60-80 parts of a high hydroxypropionic acid dispersion body, 8-12 parts of nano silica sol, 0.2-1 part of methyl trimethylsilane, 0.5-2 parts of silicon dioxide aerogel, 0.1-0.2 part of a defoaming agent, 0.1-0.2 part of a leveling agent, 0.1-0.5 part of a pH regulator, 3-5 parts of a film formation auxiliary agent, 0.3-1 part of a wetting agent, 0.2-1 part of a thickener, 0.2-0.8 part of a dispersant, and 5-15 parts of deionized water; and a component B comprising 65-70 parts of a hydrophilic isocyanate curing agent and 30-35 parts of dimethoxy dipropylene glycol; the components are mixed evenly according to the ratio of the component A to the component B to water of 100 to 15 to (10-20). The wood paint is environmentally friendly and safe, and an obtained paint film has good heat resistance and scalding resistance.

Description

technical field [0001] The invention relates to the field of paints, in particular to a water-based two-component inorganic modified heat-resistant wood varnish which can be used on the surface of office furniture and its preparation method and application method. Background technique [0002] The wood paint on the surface of office furniture must have good boiling water resistance and cigarette butt scalding resistance. At present, the commonly used wood paint on the surface of office furniture is an oily system room temperature drying type coating. Ironing performance is poor. At the same time, oil-based wood lacquers are being gradually replaced by water-based wood varnishes due to serious pollution and non-environmental protection. Their development is limited. Cannot be used in high-end office furniture.
