Problems solved by technology

Since this type of coating is still a baking type coating, although the baking temperature is much lower than that of PTFE, about 230°C, it cannot be used on site and requires factory processing, which also restricts the further promotion of fluorocarbon coatings.

Abstract

The invention relates to a formula of elastic fluorocarbon paint. The formula comprises the following ingredients: 40-50% of fluorocarbon resin, 15-20% of elastic resin, 0.3-0.5% of a wetting agent, 0.3-0.5% of a dispersant, 0.5-1% of a leveling agent, 15-20% of aluminium powder, 0.1-0.2% of an antifoaming agent, 0.1-0.5% of an anti-settling agent, 0-0.5% of a drier and 15-20% of a solvent. Long straight chain and low branched chain of a high-molecular elastic cross-linking agent react with a fluorine-containing polymer to form a highly-straight-chain and low-branched-chain polymer, the structure of which is jagged. The ultimate embodiment of properties is reflected in appropriate surface strength, excellent elasticity, telescopic springback function, high tensile strength and fracture resistance, low surface polarity and strong resistance to soiling and weatherability.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based elastic fluorocarbon paint and its formulation which can be widely used in the fields of protection, decoration, and decoration of internal and external walls, concrete surfaces, inorganic and organic materials surfaces, and the like. Background technique [0002] The earliest "fluorocarbon coating" was actually born as early as 1938. It is the well-known Teflon coating of DuPont, that is, copolymers such as polytetrafluoroethylene (PTFE) and polyperfluoropropylene (FEP). This kind of material has unique and excellent heat resistance (180℃-260℃), low temperature resistance (-200℃), self-lubricity and chemical stability, etc., and is called "corrosion-resistant, never-stick Teflon" , Fluorocarbon paint is generally divided into three fluorine and tetrafluoride, tetrafluoride has higher anticorrosion performance. Due to the extremely high liquefaction temperature require...
