preparation example Construction

[0043] As a general inventive concept, the present invention also provides the preparation method of above-mentioned waterborne feel paint, comprises the following steps:

[0044] (1) Put the polyester-modified water-based elastic resin into the container, then put into the substrate wetting agent, dispersant, elastic powder, matting powder, some additives and water to mix, fully stir and disperse to obtain a mixed solution;

[0045] (2) Stirring the mixed solution in step (1) while adding polyester resin, remaining additives and water, stirring, filtering and dispersing to obtain a coating component;

[0046] (3) The coating component and the curing component are divided into packages to obtain a water-based touch coating.

[0047] The preparation method of the above-mentioned water-based touch paint has a simple preparation process. First, the modified water-based elastic resin is mixed with a substrate wetting agent, a dispersant, elastic powder, a matting powder, some additi...

Embodiment 1

[0053] The parts by mass of the water-based feel paint in Example 1 are listed in Table 1.

[0054] Table 1 The composition of each component of the water-based feel paint

[0055]

[0056] The preparation method of above-mentioned waterborne feel paint is as follows:

[0057] (1) Mix polyester-modified water-based elastic resin, polyether siloxane copolymer, acetylene glycol, high molecular weight block copolymer, polyurethane color beads, silica, part of polysiloxane copolymer and water , disperse at 1500r / min for 20min to a particle size of 15μm to obtain a mixed solution;

[0058] (2) Add polyester resin, polysiloxane-polyether copolymer, remaining polysiloxane copolymer and water to the mixed solution in step (1), stir at 1000r / min for 15min, and filter with 200 mesh to obtain a coating composition point.

[0059] (3) 80% by weight of the isocyanate curing agent in the curing component and 20% by weight of the diluent are mixed, filtered with 300 mesh, and the curin...

Embodiment 2

[0062] The parts by mass of the water-based feel paint in Example 2 are listed in Table 2.

[0063] Table 2 The composition of each component of the water-based feel paint

[0064]

[0065] The method for preparing the water-based feel paint in this embodiment is the same as that in Embodiment 1.

[0066] Add an appropriate amount of water to the above-mentioned water-based touch paint, spray it on the surface of the ABS+PC material, control the dry film thickness at 40 μm, bake at 90°C for 30 minutes, and test at 90°C for 8 hours. The test results refer to the table 4. The results show that the adhesion of the water-based touch paint is 5B, the hardness is H, and the hand feel is fine and smooth.

Abstract

The invention discloses an aqueous hand-feeling coating. The aqueous hand-feeling coating comprises, by weight, 40 to 60 parts of a polyester-modified water-based elastic resin, 5 to 10 parts of a polyester resin, 0.6 to 1.3 parts of a base wetting agent, 0.3 to 0.7 parts of a dispersing agent, 3 to 7 parts of elastic powder, 3 to 6 parts of matting powder, 0.7 to 2 parts of an aid and 23 to 32 parts of water. The aqueous hand-feeling coating has the characteristics of smooth paint, good adhesion and high hardness. A preparation method of the aqueous hand-feeling coating comprises two dispersion processes and physical mixing. Through the preparation method, the aqueous hand-feel coating has small particle sizes, is easy to disperse and is evenly distributed. The preparation method is simple and is suitable for large-scale use.

Description

technical field [0001] The invention relates to the field of water-based coatings, in particular to a water-based hand-feeling coating. In addition, the invention also relates to a preparation method and application of the water-based touch paint. Background technique [0002] With the improvement of people's awareness of environmental protection, water-based coatings are accepted by more people as a more environmentally friendly coating material, and the prospects for water-based coatings are getting better and better. Water-based paint uses water as a solvent, saving a lot of resources. Water-based coatings eliminate the risk of flooding during construction and reduce air pollution. Water-based coatings only use a small amount of low-toxic alcohol ether organic solvents, which improves the working environment and has a significant effect on reducing pollution and saving resources. [0003] However, there are many gaps between the performance of water-based touch coating...
