Problems solved by technology

For products without coating protection, the external environment will cause a certain degree of corrosion to the product shell, affecting the appearance and service life of the product
[0003] Texture effect coating technology is based on ordinary surface coating, through the difference in fluidity changes during coating construction, and by adjusting the coating formula, a surface protection paint film with different visual and tactile effects is produced. This coating produces The protective paint film can meet various performance tests, and a kind of artistic effect paint that can realize the function of protecting electronic products through the performance test; but the VOC of leather texture paint in the related art is higher and the imitation leather texture effect is poor

Abstract

The invention discloses leather texture primer as well as a preparation method and application thereof. The leather texture primer is prepared from the following raw materials: low-hydroxyl acrylic resin, high-hydroxyl acrylic resin, polysiloxane, a leather texture modifier and an auxiliary agent. The primer has excellent wear resistance, leather texture imitation effect and low VOC content; wherein the low-hydroxyl acrylate resin enhances the adhesive force of the finish paint to the leather texture primer and the base material; the high-hydroxyl acrylic resin improves the mechanical properties (wear resistance, hardness and tensile strength) of the paint film; the leather texture modifier improves various properties and leather texture imitation effect (artistic relief effect) of the paint film by adjusting the flow degree of the paint film during curing.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a skin texture primer and a preparation method and application thereof. Background technique [0002] With the continuous progress of society and the continuous improvement of people's living standards, various electronic or electrical products have been widely used in people's daily life. The shells of these products are mostly made of plastic or plastic materials. In order to increase the diversification of product appearance and make the product more beautiful and decent, it is necessary to spray a layer of paint film on the surface of the substrate, which has the effect of beautiful decoration and has stain resistance. , wear resistance and scratch resistance. For products without coating protection, the external environment will cause a certain degree of corrosion to the outer shell of the product, which will affect the appearance and service life of the product. [0003] Texture e...
