Abstract

The invention discloses molecular chain self-spinning fluorine-containing UV resin and a preparation method thereof. The molecular chain self-spinning fluorine-containing UV resin is prepared from thefollowing raw materials in parts by weight: 100 parts of polyvinyl alcohol, 200-400 parts of anhydride, 25-70 parts of an ethylene-epoxy bifunctional monomer and 400-500 parts of fluorine-containingalcohol. The molecular chain self-spinning fluorine-containing UV resin prepared by the preparation method has the advantages of high fluorine content, high curing speed, strong adhesion property, good hydrophobicity and the like.

Description

technical field [0001] The invention relates to the field of polymer resin preparation, in particular to a molecular chain self-rotating fluorine-containing UV resin and a preparation method thereof. Background technique [0002] Due to its environmental protection, no VOC emissions, low energy consumption, fast curing and other advantages, UV light curing technology has become a new technology of green coating materials with great development potential in the future. With the upgrading of social industrial level and people's consumption level, more performance requirements are put forward for UV curable resin, especially high smoothness, high hydrophobicity, high and low temperature resistance, acid and alkali corrosion resistance, etc. [0003] Fluorine-containing UV resins have great application potential due to the excellent hydrophobicity and weather resistance of fluorine units. At present, fluorine-containing UV curable resins have the following problems: first, the ...
