Problems solved by technology

However, with the development needs of the coatings industry, domestic enterprises are increasingly aware of the importance of rheological thickeners. Organic bentonite and silica can no longer meet the growing demand for rheological agents in the coatings industry. The company began to develop and adopt polyamide wax rheological agent, and has reached the international level

Abstract

The invention discloses polyamide wax modified sericite powder, and a preparation method and an application thereof. The polyamide wax modified sericite powder is obtained by taking polyamide wax as a modifier and conducting surface modification on sericite, and the mass ratio of polyamide wax to the sericite is (0.1-10):100. The polyamide wax modified sericite powder can serve as a coating rhelogy assistant, the solvent resistance grade of the rhelogy assistant is increased, and post thickening in a storage stage is avoided.

Description

1. Technical field [0001] The invention relates to a method for preparing a polyamide wax surface-modified sericite functional filler and its application, which is mainly used in chlorinated rubber coatings, high-solid content coatings, epoxy coatings, air-drying industrial coatings, route paints, hammer patterns Paints, decorative paints, polyurethane paints, asphalt compounds, antifouling paints, mud fills, thick build paints, adhesives, sealing materials and other fields, as functional materials, in addition to enhancing acid and alkali resistance, UV protection, heat resistance In addition to properties such as resistance, wear resistance, insulation, mechanical strength, etc., it can also endow the filled material with a thixotropic structure, improve the suspension performance of the pigment, control sag without sacrificing flow and leveling, and endow storage stability and reproducibility. Presentity. 2. Background technology [0002] 1. Rheological properties of coa...
