Abstract

The invention discloses water-soluble acrylic alkyd resin and a preparation method thereof. The water-soluble acrylic alkyd resin is prepared from the following raw materials in percentage by weight: 40-50% of flaxseed oil, 15-20% of trimethylolpropane, 3-6% of pentaerythritol, 2-5% of phthalic acid, 3-6% of m-phthalic acid, 8-12% of trimellitic anhydride, 30-40% of butyl acrylate, 4-8% of glycidol methacrylate, 3-6% of acrylic acid, 20-25% of hydroxyethyl methacrylate, 10-15% of styrene, 20-30% of butyl glycol ether, 5-10% of xylene and 2-4% of composite initiator. The water-soluble acrylic alkyd resin disclosed by the invention has the advantages of excellent durability, weatherability, wettability, solvent resistance, corrosion resistance, flexibility, gloss and color retention, quick drying, high hardness, storage stability and the like, and the use performance is improved on the basis that the defects of poor storage stability, poor wettability and the like of the ordinary alkyd resin are overcome, so that the application field of the water-soluble acrylic alkyd resin is enlarged.

Description

technical field [0001] The invention relates to a water-soluble acrylic alkyd resin and a preparation method thereof, belonging to the technical field of alkyd resin synthesis. Background technique [0002] With the further improvement of environmental regulations and the purpose of reducing the load on the earth, water-soluble resins with low or zero VOC emissions have become a hot spot in research and development. Water-soluble alkyd resin is the synthetic resin with the largest output and the earliest development in my country. It has the characteristics of gloss and color retention, durability, hardness, gloss and flexibility. It can be made into coatings with various properties and is widely used in railway vehicles. , Insulation and anti-corrosion and other fields have become the development direction of green and environmental protection in the field of coatings. However, there are still some problems in water-soluble alkyd resins at present, such as resin storage sta...
