Abstract
The invention relates to a heat resistant aluminum color epoxyorganosilicon paint. The paint is characterized in that the paint comprises, by weight, 100 parts of a component I which is an H61-1 epoxy modified organosilicon resin; 30 parts of a component II which comprises 80-100 parts of a polyamide resin, 40-50 parts of toluene, 40-50 parts of butanol and 10-20 parts of cyclohexanone; and 20 parts of a component III which is floating aluminum powder. The invention also relates to a preparation method of the paint. The preparation method comprises the following steps: 1, preparing the H61-1 epoxy modified organosilicon resin; 2, adding the polyamide resin, toluene, butanol and cyclohexanone to a burdening basin, stirring them for 15min at a low-medium speed of 200-400r / min, and packaging after the solid test qualification; 3, packaging the floating aluminum powder after examining; and 4, mixing the component I, the component II and the component III according to a ratio of 100:20:20, allowing them to stand for 20min, and packaging them after examining. The paint has the following beneficial effect: the paint possess excellent physical and chemical performances of decorativeness, heat resistance, salt spray resistance, salt water resistance, water resistance, cold resistance, oil resistance, hydrocarbonsolvent resistance, adhesion force, impact, flexibility and the like.
Description
technical field [0001] The invention belongs to chemical coatings, in particular to an aluminum-colored epoxy organosilicon heat-resistant paint and a preparation method thereof. Background technique [0002] The existing epoxy silicone resin or paint can meet the general decoration, heat resistance and protection requirements, but for special performance requirements such as salt spray resistance, heat and humidity resistance, cold resistance, salt water resistance, lubricating oil resistance, hydrocarbon liquid resistance , heat resistance above 500 ℃ and other properties can not meet the requirements. Epoxy-modified silicone resin, as a film-former of heat-resistant paint, has excellent high temperature resistance, atmospheric resistance and heat and humidity resistance, and has good adhesion to metals. It is indispensable for special purposes such as high-temperature anti-corrosion and high-temperature insulation. Material. The key reason is that the commercially avail...
