High-temperature wear-resistant sericite pearlescent pigment

Abstract

The invention discloses a high-temperature wear-resistant sericite pearlescent pigment which comprises the following raw materials in parts by weight: 100-120 parts of sericite powder body, 30-38 parts of titanium powder, 30-38 parts of zinc powder, 22-30 parts of chrome yellow, 22-30 parts of cobalt blue, 12-20 parts of iron powder, 12-20 parts of methyl hydrogen-containing silicon oil, 10-18 parts of polyvinyl alcohol, 10-18 parts of colorant and 5-7 parts of coupling agent. By using the sericite as the main raw material to manufacture the pearlescent pigment, the pearlescent pigment has the advantage of available raw materials and is easy to manufacture. The titanium powder and zinc powder are added and mixed to coat the sericite surface, thereby obviously improving the pearlescent effect. The added colorant and coupling agent can obviously enhance the dispersity of the pearlescent pigment and greatly enhance the wear resistance, and the pearlescent pigment has high temperature resistance. The added cobalt blue, iron powder and methyl hydrogen-containing silicon oil can change the physical properties of various raw materials. The brightness and chroma of the pearlescent pigment are greatly enhanced, the wear resistance of the pearlescent pigment is greatly enhanced, and the pearlescent pigment has high temperature resistance and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of high-temperature wear-resistant sericite pearlescent pigments, in particular to a high-temperature wear-resistant sericite pearlescent pigment. Background technique [0002] The excellent performance of pearlescent pigments makes it a new idea in today's color field and has high commodity value. Pearlescent pigments are widely used in various fields, such as automobile, motorcycle, bicycle coating, powder coating, architectural coating, pearlescent ink, pearlescent leather, pearlescent plastic products, pearlescent cosmetics, papermaking, printing and dyeing, printing, rubber, ceramics and other industries. [0003] However, the current research on high-grade pearlescent pigments in my country still cannot meet the needs of the market, and most of them need to be imported from abroad, especially high-temperature wear-resistant pearlescent pigments, which are very expensive.

[0003] However, the current research on high-grade pearlescent pigments in my country still cannot meet the needs of the market, and most of them need to be imported from abroad, especially high-temperature wear-resistant pearlescent pigments, which are very expensive

The interference effect between the layers of the finished pigment is weak, and there are shortcomings such as low brightness and saturation, and easy to fade under high temperature conditions. For this reason, we have proposed a high-temperature wear-resistant sericite pearlescent pigment
