Abstract

The invention relates to an environmental protecting multifunctional coating and its preparing method, which employs organic-inorganic composite raw charge with the weight percentage: organosilicon resin 10-15%, silicasol 20-25%, silver oxide 40-45%, cupric oxide 1-3%, bengala 1-5%, nickel oxide 1-3%, filling agent 20-25%, dispersants 0.05-0.10%, thickening agents 0.05-0.10%, wedding agent 0.05-0.10% and foam killer 0.05-0.10%, and obtains products after proportioning, commingle, milling, mixing round and natural drying. This invention is widely used at the surface of metal, inorganic metal(such as glass, ceramic) materials to have the function of heat resisting and electric conduction with easy preparing pressure, easy-controlled, dispensing with calcining technology, energy-saving. environmental-protecting, high temperature of heat resisting, low cost of manufacture and good product performance.

Description

technical field [0001] The invention belongs to the field of organic-inorganic composite materials, and specifically relates to an environment-friendly multifunctional coating and a preparation method thereof. The composite coating prepared by the composite coating has functions such as high temperature resistance (600-900°C), electromagnetic induction, etc., and can be applied to metal, inorganic Non-metallic (such as glass, ceramics) and other material surfaces. Background technique [0002] Existing high-temperature-resistant coatings are mainly the most commonly used with organosilicon high-temperature-resistant coatings and inorganic silicon high-temperature-resistant coatings. Silicone heat-resistant coatings have good heat resistance (pure silicone can withstand 200-300°C, and the coating prepared with organic silicon as the base material and inorganic filler can withstand the temperature of about 1000°C), water resistance, and electrical insulation. And good mechani...

AI Technical Summary

Problems solved by technology

Silicone heat-resistant coatings have good heat resistance (pure silicone can withstand 200-300°C, and the coating prepared with organic silicon as the base material and inorganic filler can withstand the temperature of about 1000°C), water resistance, and electrical insulation. And good mechanical properties, but low hardness, poor flame resistance

Inorganic high-temperature-resistant coatings have good heat resistance (heat resistance temperature greater than 1000°C) and high hardness, but the coating is brittle and must be heated to a higher temperature or other complicated pretreatments to cure, and the processing requirements for the substrate are also more demanding. for strict

Most of the electromagnetic induction coatings are composed of metal oxides such as silver oxide and binders (generally glass composed of lead oxide, boron oxide, silicon oxide, etc.), and the coating construction must be cured after high temperature treatment. Boron and other oxides, the coating is not environmentally friendly, and the expansion coefficient is extremely large, so it is not suitable for substrates that require the expansion coefficient of the coating
