preparation example Construction

[0022] The preparation method of the first component of the embodiment of the present invention is as follows:

[0023] Step 1: Mix unsaturated polyester resin, polyether resin, and dispersant, and disperse at a medium speed for 10-15 minutes until fully uniform, ensuring that the viscosity is 10000±500CPS / 25°C;

[0024] Step 2: Add filler to the solution obtained in Step 1, and disperse evenly;

[0025] Step 3: Add defoamer, leveling agent, anti-greening agent, 3-5 parts by weight of unsaturated solvent to the mixture obtained in step 2, and disperse evenly;

[0026] Step 4: Add the remaining unsaturated solvent to the mixture obtained in Step 3, and disperse until the fineness is ≤50um, and the viscosity is controlled at 10000±500CPS / 25°C.

Embodiment 1

[0028] Component A of the embodiment of the present invention consists of 65 parts by weight of unsaturated polyester resin, 2 parts by weight of polyether resin, 0.2 parts by weight of dispersant, 15 parts by weight of transparent powder, 3 parts by weight of talcum powder, 0.3 parts by weight of The antifoaming agent of 0.3 weight part, the leveling agent of 0.1 weight part, the anti-greening agent of 0.1 weight part, the unsaturated solvent composition of 3 weight parts;

[0029] Component B consists of 40 parts by weight of ethyl acetate, 25 parts by weight of dimethyl carbonate, and 35 parts by weight of styrene.

Embodiment 2

[0031] Component A of the embodiment of the present invention consists of 75 parts by weight of unsaturated polyester resin, 3 parts by weight of polyether resin, 0.3 parts by weight of dispersant, 20 parts by weight of transparent powder, 5 parts by weight of talcum powder, 0.5 parts by weight of The defoamer, the leveling agent of 0.5 weight part, the anti-greening agent of 0.2 weight part, the unsaturated solvent composition of 5 weight parts;

Abstract

The invention provides a thick coating type PE clear primer. The thick coating type PE clear primer comprises a component A, a component B, a component C and a component D, wherein the component A iscomposed of, in parts by weight, 65 to 75 parts of unsaturated polyester resin, 2 to 3 parts of polyether resin, 0.2 to 0.3 part of a dispersing agent, 18 to 25 parts of a filling agent, 0.3 to 0.5 part of an antifoaming agent, 0.3 to 0.5 part of a leveling agent, 0.1 to 0.2 part of an anti-greening agent and 3 to 5 parts of an unsaturated solvent; the component B is a diluent; the component C isketone peroxide; and the component D is a curing accelerator. By adopting the combination of the unsaturated polyester resin and polyether resin, the coating has the advantages of favorable sinking resistance, favorable transparency, high filling property, no cracking and the like, and can be widely used for primer coating of high-grade solid wood and customized furniture.

Description

technical field [0001] The invention relates to a wood primer, in particular to a thick coating type PE clear primer. Background technique [0002] As a traditional material in China, wood is deeply loved by Chinese people. With the improvement of people's living standards, the wooden furniture market has been widely developed. Before leaving the factory, wooden furniture needs to be painted multiple times to extend the service life of the wood. However, the existing wood primers have disadvantages such as slow drying speed, poor filling property, general adhesion, poor transparency of thick coatings, and easy cracking, which has been a problem that has plagued the coatings industry. Contents of the invention [0003] The invention provides a thick coating type PE clear primer to improve the physical properties of the coating. [0004] The invention provides a kind of thick coating type PE clear primer. The thick coating type PE clear primer comprises component A, compon...
