Abstract

The invention provides a preparation process and application method for a paint additive, belonging to the technical field of decorative coatings. The preparation process for the paint additive comprises the following steps: 1) preparation of raw materials; 2) preparation of wheat bran powder; 3) preparation of a basic additive; 4) preparation of a mixed material B; and 5) preparation of the paint additive. The paint additive is scientific and reasonable in the ratio of the raw materials; when added into paint, the paint additive can improve the wear resistance and scratch resistance of a material sprayed with the paint, reduce the depainting rate of the paint and decrease irritant smell; moreover, the preparation process is simple and controllable in process, low in cost and easy for promotion and application; and the production process of a diluent or the paint additive has no pollution to machines and a production environment and accords with the ecological concept of environmental protection.

Description

【Technical field】 [0001] The invention relates to the technical field of decorative coatings, in particular to a preparation process and an application method of a paint additive. 【Background technique】 [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. This kind of paint can be coated on the surface of objects by different construction techniques to form a solid film with firm adhesion, certain strength and continuous. The films formed in this way are collectively referred to as coating films, also known as paint films or coatings; most of the traditionally used solvent-based paints contain carcinogens such as benzene, toluene, xylene, TDI, VOC, etc. When used for interior decoration, the paint film During the drying process, a large amount of toxic organic solvents volatilize, emitting a pungent odor that is harmful to human health. [0003] Modern paints are gradually ...
