Abstract

The invention relates to a perfluoro alkyl ethyl acrylic ester-modified single-component acrylic resin and a preparation method as well as application thereof. The perfluoro alkyl ethyl acrylic ester-modified single-component acrylic resin has the structural formula which is shown in the specification, wherein n is equal to 4, 6 or 8; and the molecular weight is 40,000-55,000. The preparation method comprises the following steps of: adding a solvent into a reaction vessel and heating to 60-80 DEG C; uniformly mixing methyl methacrylate, acrylic acid, butyl acrylate, hydroxyethyl acrylate and perfluoro alkyl ethyl acrylic ester type monomer with an initiator and dropwise adding for 2-3 hours; preserving heat for 0.5-1 hour; and cooling to 40-70 DEG C and discharging. The resin prepared by the invention has high thermal stability and chemical resistance stability and low surface energy and is used as a main raw material of a paint; and a coating also has low surface energy, strong water-proof and oil-proof capacities and high weather resistance, corrosion resistance and aging resistance, has superior mechanical performance and high glossiness of an acrylic ester paint, can be cured at normal temperature and is easy and convenient to use.

Description

technical field [0001] The invention relates to a one-component perfluoroalkyl ethyl acrylate modified acrylic resin and its preparation method and application. Background technique [0002] Fluorine-containing polymers are mainly used as raw materials for coatings and are used in various fields such as construction, chemical industry, electrical and electronic industry, machinery industry, aerospace industry, and household products. Because the fluorine element introduced into the fluoropolymer has a large electronegativity and strong carbon-fluorine bond energy, it has particularly superior weather resistance, heat resistance, low temperature resistance, chemical resistance, and unique non-stick and low friction sex. [0003] The first-generation fluoropolymers are mainly represented by homopolymers of fluoroolefin monomers, such as PTFE, PVDF, PVF, etc. This type of thermoplastic fluorocarbon resin has a regular structure, and the polymer itself is in a semi-crystalline ...
