Abstract

The invention discloses a water-based hydroxyl acrylic resin facilitating deep machining, a water-based acrylic amino baking finish, a preparation method and a metal workpiece. The water-based hydroxyl acrylic resin is prepared from acrylic acid, methyl methacrylate, butyl acrylate, butyl methacrylate, vinyl versatate, cyclohexyl methacrylate, hydroxyethyl acrylate, 3-thiohydracrylic acid, an initiator, an oxidizing agent, a reducing agent, an organic solvent and water. The vinyl versatate and the 3-thiohydracrylic acid are introduced to a monomer part of the water-based hydroxyl acrylic resin, and branched chains in the vinyl versatate and the 3-thiohydracrylic acid make resin molecule arranged smoothly, so that a coating prepared by adopting the prepared water-based hydroxyl acrylic resin is very good in coating toughness, and a metal surface has good toughness after being coated. Therefore, the requirements of deep machining of a lot of metal workpieces can be met.

Description

technical field [0001] The invention relates to the field of metal baking varnish, and mainly relates to a water-based hydroxyacrylic resin and a water-based acrylic amino baking varnish which are beneficial to deep processing, a preparation method and a metal workpiece. Background technique [0002] Compared with solvent-based metal baking varnishes, water-soluble metal baking varnishes have better aging resistance, low toxicity and less pollution. In the prior art, the main resin types of water-soluble metal baking varnishes are epoxy resin, polyester resin and acrylic resin. Among them, although acrylic resin has many advantages such as excellent weather resistance, color retention, high gloss and good film-forming compactness, it is not widely used in water-soluble metal baking varnishes due to its hard and brittle characteristics, which are not conducive to deep processing. [0003] For example, Chinese invention patent CN102492354A discloses a water-based environment-...
