Abstract

The invention discloses polyester modified hydroxyl type fluorinated acrylate resin and a preparation method thereof. On the basis of double-bond hydroxyl type polyester, (methyl) acrylics, (methyl) fluorinated acrylics, (methyl) acrylic acid and hydroxyl (methyl) acrylate monomers are subjected to graft copolymerization through solution polymerization, and hybridization of fluorinated acrylate resin and polyester resin is realized; and during preparation of fluorine resin, the polyester resin is introduced creatively to perform hybridizing modification on the fluorine resin, features of the fluorine resin are kept while the cost of the fluorine resin is reduced, meanwhile, the solid content is higher, and the resin has the better environmental protection performance. Used synthetic raw materials are common raw materials, the requirements for a production technology are not high, the synthesis cost of the fluorine resin is low, the performance of 2KPU (two-component polyurethane) varnish prepared with the fluorine resin is excellent, and prepared coatings are applicable to various base materials such as wood products, metals, plastics, concrete and the like.

Description

Technical field:

[0001] The invention relates to a polyester-modified hydroxyl type fluorinated acrylate resin used for substrates such as cement, wood and metal, and a preparation method thereof. The invention synthesizes a new type of fluororesin with wide application and high cost performance by introducing unsaturated double bonds into the polyester macromolecular chain and copolymerizing it with fluorine-containing acrylate monomers. Background technique:

[0002] Although foreign fluorine coatings have been developed for more than 20 years, the variety is still relatively single, and the performance of coatings needs to be improved. Although my country has made some progress, compared with foreign countries, there is still a big gap in the performance of coatings. Due to the low polarity of the F-C bond in the fluorocarbon resin, the fluorocarbon polymer has low surface energy. Compared with other resins, the fluorocarbon resin has excellent water resistance, oil repe...
