Abstract

The invention discloses high-temperature resistant antibacterial non-stick paint. The paint has remarkable antibacterial effect and obvious non-stick effect. A formulation of the paint basically comprises the following components: a, at least one resin accounting for 65 percent of the paint; b, wax powder accounting for 5 percent of the paint; and c, nano silver powder accounting for 0.2 to 0.6 percent of the paint. The formulation further comprises talc powder accounting for 5 percent of the paint, flatting powder accounting for 3.5 percent of the paint, butanone accounting for 6.6 to 7 percent of the paint, and carbon black accounting for 1.5 percent of the paint. The formulation further comprises dispersing aid accounting for 2 percent of the paint, and non-stick aid accounting for 0.8percent of the paint. The paint has the following advantages of good thermal stability, remarkable environmentally-friendly and antibacterial effects, obvious non-stick effect and preferable performance in the aspects of corrosion resistance, adhesive force, innocuousness, hardness and the like. Meanwhile, the paint has simple manufacturing process, low cost and better application prospect, and can well meet the demands of domestic markets.

Description

【Technical field】 [0001] The invention relates to a preparation method of a high-temperature-resistant antibacterial and non-stick coating applied to cooking utensils, medicine, food and special purposes, and belongs to the technical field of chemical coatings. 【Background technique】 [0002] Non-stick coating is a special coating whose coating surface is not easily adhered by other sticky substances or easily removed after adhesion. This kind of coating is widely used in household appliances, cooking utensils, automobiles, machinery, chemical industry and other industries due to its anti-adhesive properties such as extremely low surface energy, small friction coefficient and easy sliding. As a kind of environmentally friendly special coating with strong practicability and high technical content, non-stick coating has attracted more and more attention from coating research and development workers. The technology of non-stick coatings is complex, how to disperse fluororesin ...
