Problems solved by technology

[0002] At present, the surface treatment agent that acts on the surface of plastic, wood, metal, etc. for antifouling and waterproof treatment, due to the uneven dispersion of the coating surface after application and the excessive surface tension, this makes the surface of the substrate coating very easy to be polluted and difficult clean, and thus low surface energy hydrophobic coatings have received much attention in the field of scientific research

Abstract

The invention relates to a fluorine-modified water-based alkyd resin and a preparation method thereof. Its components are composed of vegetable oil fatty acids, organic acid anhydrides, polyols, epoxy resins, fluorine monomers, acrylic monomers and deionized water; The fluorine-modified water-based alkyd resin prepared by the invention can be formulated into one-component water-based coatings, two-component water-based coatings, and normal-temperature curing coatings. The fluorine-modified water-based alkyd resin prepared by the present invention has good adhesion, stain resistance, water resistance, alkali resistance, durability, hydrophobicity, low dielectric constant and other properties, and is widely used in marine fields, wood Coatings, anti-fouling and water-repellent coatings, which can also be used in radome materials, have enormous application potential.

Description

technical field [0001] The invention relates to a preparation method of a modified water-based alkyd resin, in particular to a fluorine-modified water-based alkyd resin with uniform structure, low cost, extremely low surface tension, and good hydrophobic and antifouling functions, belonging to synthetic resins Technical field: The present invention combines the characteristics of easy-to-obtain alkyd resin raw materials, low cost and small fluorine atomic radius, and the prepared fluorine-modified water-based alkyd resin can be used for substrates such as wood, metal, and plastic. Background technique [0002] At present, the surface treatment agent that acts on the surface of plastic, wood, metal, etc. for antifouling and waterproof treatment, due to the uneven dispersion of the coating surface after application and the excessive surface tension, this makes the surface of the substrate coating extremely easy to be polluted and difficult to Clean, and thus low surface energy...
