Embodiment 1

[0037] Example 1: After mixing the acrylic resin, 3% inorganic nano-denatured oligomer, 22% organic solvent, and 15% aluminum potassium silicate, which are respectively 55% by mass, they are dispersed at a high speed, and then ground, Wherein the grinding temperature is lower than 60 degrees, and after the grinding is completed, a special coloring paste with a mass percentage content of 5% is added for color blending.

Embodiment 2

[0038] Example 2: Mix the acrylic resin, 3% inorganic nano-denatured oligomer, 12% organic solvent, and 15% aluminum potassium silicate in mass percentages of 65% and then disperse at a high speed, and then grind, Wherein the grinding temperature is lower than 60 degrees, and after the grinding is completed, the mass percentage is 5% by adding a special coloring paste for color blending.

Embodiment 3

[0039] Example 3: Mix the acrylic resin, 3.5% inorganic nano-denatured oligomer, 13% organic solvent, and 15.5% potassium aluminum silicate with a mass percentage content of 60% respectively, and then perform high-speed dispersion, and then grind, Wherein the grinding temperature is lower than 60 degrees, and after the grinding is completed, the mass percentage is 8% by adding a special coloring paste for color blending.

Abstract

The invention discloses a PU double-component multifunctional undercoat and a preparation method thereof. Acrylic resin is matched with isocyanate. Lithium aluminium silicate is employed as a filling material for enhancing a rubbing property of the undercoat, covering traces caused by an abrasive paper and improving a covering capability. The undercoat is excellent in functionality, is good in the rubbing property and recoatability. In a production line, the undercoat can increase a yield in the production line and can reduce scrap of materials. Thickness of a film of the PU double-component multifunctional undercoat is liable to control and a protective property of the film to a coating can be enhanced. The PU double-component multifunctional undercoat is excellent in wear resistance and scrape resistance and a good storage condition is provided .The PU double-component multifunctional undercoat is high in hardness and toughness, is excellent in flexibility and anti-chemical performance, is low in contractility and is not liable to deform. The PU double-component multifunctional undercoat is adjustable in surface glossiness so that a high glossiness and a matted glossiness are both available. The PU double-component multifunctional undercoat also enables color adjustment to be available so that selectivity of color is more diversified.

Description

technical field [0001] The invention relates to a primer coating, in particular to a PU two-component multifunctional primer, which belongs to the technical field of chemical coating products. Background technique [0002] The unique and aesthetic appearance of products has become the mainstream of today's society. Especially for a series of plastic products such as mobile phones, computers, notebooks, and mice, the appearance quality is more important. At present, there are more and more types of materials at home and abroad, and the molding quality of the materials is uneven, resulting in many defects in the materials. Therefore, in order to solve the problems on the materials, it is necessary to rely on spraying primer to solve this problem. The primer needs to have a good filling Seams and coverings are needed to cover uneven materials or defects in materials. After the traditional paint is applied to the above products, it not only has low toughness, easy deformation, ...
