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 a water-based elastic fluorocarbon paint. The formula comprises 20-25% of water, 0.3-0.5% of a dispersant, 0.2-0.3% of a wetting agent, 0.3-0.5% of an antifoaming agent, 15-20% of rutile titanium dioxide powder, 15-20% of a filling material, 0.2-0.3% of a multifunctional auxiliary agent, 0.5-1% of a coalescing agent, 0.5-1% of glycol, 10-15% of a fluorocarbon emulsion, 20-30% of an elastic emulsion, 0.3-0.5% of a thickening agent and 0.1-0.3% of a leveling agent. 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 formula that can be widely used in the fields of protection, decoration and decoration of interior and exterior walls, concrete surfaces, inorganic and organic material surfaces, and the like. Background technique [0002] The earliest "fluorocarbon coating" was born as early as 1938. It is the well-known DuPont Teflon coating, that is, polytetrafluoroethylene (PTFE), polyperfluoropropylene (FEP) and other copolymers. This kind of material is known as "corrosion-resistant, non-stick Teflon" due to its unique and excellent heat resistance (180°C-260°C), low temperature resistance (-200°C), self-lubrication and chemical stability. , Fluorocarbon paint is generally divided into trifluoro and tetrafluoro, tetrafluoro anti-corrosion performance is higher. Due to the extremely high liquefaction temperature required for use, the dispers...
