Abstract

The invention discloses a high-wave-absorbing easy-to-clean coating and a preparation method thereof. The coating is composed of, by weight, 20-30 parts of fluorosilicon resin, 5-10 parts of a curingagent, 5-10 parts of sodium-based bentonite, 3-7 parts of an iron-containing compound, 1-3 parts of barium titanate, 2-5 parts of low-surface energy modified nano-material, 3-6 parts of inorganic filler, 0.5-1.5 parts of a wave-absorbing agent, 0.3-0.7 parts of a thickener, 0.2-0.6 parts of a dispersant, and 22-30 parts of deionized water. The coating has excellent wave-absorbing performance and is easy to clean.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-absorbing and easy-to-clean coating and a preparation method thereof. Background technique [0002] Most of the microwave-absorbing materials used in existing microwave ovens or microwave ovens are to mix and disperse the microwave-absorbing powder in the resin, and solidify it on the surface of the metal or ceramic plate through high temperature to form a 2 mm wave-absorbing layer, so as to achieve microwave absorption by the baking pan. Ability to achieve the purpose of baking and grilling food. [0003] However, ferrite is often used as the absorbing material in this absorbing material, and the absorbing performance is insufficient. In addition, the absorbing layer has the problem that it is difficult to clean, which brings troubles to the actual practical use. Contents of the invention [0004] The object of the present invention is to provide a high absorbing and ...
