Black organic-silicon heat-resisting paint and preparation method thereof

Abstract

The invention discloses a black organic-silicon heat-resisting paint comprising 45-65 percent of organic silicon resin, 10-25 percent of high-temperature resisting pigment, 3-8 percent of talc powder, 5 percent of weather-resistance filling materials, 5-15 percent of mica powder, 8-15 percent of mixed glass powder, 5-10 percent of Kaolin, 2-5 percent of cosolvent and 10-20 percent of solvent. A preparation method of the black organic-silicon heat-resisting paint comprises the steps of firstly, weighing the above materials; secondly, putting the high-temperature resisting pigment, the talc powder, the mica powder, the mixed glass powder and the kaolin into a mixing tank, putting part of the organic silicon resin, cosolvent and solvent firstly and then stirring for fully mixing; thirdly, pressing the mixed materials after stirring into a sand mill for full sanding; and fourthly, according to the requirements of glossiness, putting the mixed materials after sanding into a paint formulation kettle, then adding the residual organic silicon resin, cosolvent and solvent in the mixed materials, stirring, mixing, then testing, filtering and packaging.

Description

technical field [0001] The invention relates to a black organosilicon heat-resistant paint and a preparation method thereof. Background technique [0002] Most of the heat-resistant coatings used to coat high-temperature-resistant metal components on the market today generally have a heat-resistant temperature of about 600°C. This requirement is far from meeting the heat-resistant requirements of some special products. In addition, these heat-resistant coatings not only It cannot be grilled with an open flame without high temperature baking, otherwise a lot of smoke will be generated, and it cannot be constructed at a high temperature above 200 °C, and it cannot withstand high temperatures above 800 °C. The scope of use and application are relatively small. Contents of the invention [0003] The invention discloses a black organosilicon heat-resistant paint and a preparation method thereof, which not only can be self-dried at room temperature, can withstand ultra-high temp...
