Problems solved by technology

However, the fluorocarbon coating applied on the metal surface tends to cover the base color of the metal surface, making the metal product lack aesthetic feeling
On the other hand, common fluorocarbon coatings do not have the characteristics of anti-cold feeling. After being coated on metal, it feels cold when touching the metal surface. Therefore, common fluorocarbon coatings cannot be widely used in the field of interior decoration.

Abstract

The invention relates to a cold-feeling-resistant fluorocarbon coating and a preparation method thereof. The coating comprises the following components in percentage by mass: 10%-15% of PVDF fluorocarbon resin, 5%-10% of epoxy resin, 2%-5% of a silane coupling agent, 25%-45% of isophorone, 4%-8% of propylene glycol methyl ether acetate, 15%-25% of ethyl acetate, 0.2%-0.5% of a defoaming agent, 2%-5% of nano siloxane modified fumed silica, 2%-5% of modified matting powder, 1%-2% of nano medical stone particles and 0.2%-0.5% of an alkali swelling thickener. The preparation method comprises the following steps: mixing the nano siloxane modified fumed silica, the silane coupling agent and the ethyl acetate, stirring for 25-35 minutes in an environment of 40-60 DEG C, and screening the mixture to obtain modified nano siloxane modified fumed silica; stirring the modified nano siloxane modified fumed silica, the PVDF fluorocarbon resin, the epoxy resin, the isophorone, the propylene glycol methyl ether acetate and the nano medical stone particles for 1 hour to obtain a first mixed solution; and mixing the first mixed solution, the modified matting powder and the defoaming agent for 25-35 minutes to obtain the cold-feeling-resistant fluorocarbon coating.

Description

technical field [0001] The application relates to a coating and a preparation method thereof, belonging to the field of coating production, in particular to a cold-resistant fluorocarbon coating. Background technique [0002] Fluorocarbon coating refers to the coating with fluorocarbon resin as the main film-forming substance. Due to the high electronegativity of the introduced fluorine element and the strong bond energy of carbon and fluorine, it has superior properties. Fluorocarbon coatings have good weather resistance, heat resistance, low temperature resistance, and chemical resistance, and have unique non-stick and low friction properties. However, the fluorocarbon coating applied on the metal surface tends to cover the base color of the metal surface, making the metal product lack aesthetic feeling. On the other hand, common fluorocarbon coatings do not have the characteristics of anti-cold feeling. After being coated on metal, the metal surface feels cold when touch...
