Abstract

The invention discloses a styrene-modified alkyd resin. The styrene-modified alkyd resin comprises the following raw materials in parts by weight: 50 to 60 parts of hydroxyl-terminated aliphatic hyperbranched polyester, 20 to 40 parts of oleic acid, 70 to 80 parts of tartaric acid production wastewater, 2 to 6 parts of dimethylbenzene, 25 to 30 parts of styrene, 0.7 to 1.2 parts of benzoyl peroxide amide and 30 to 50 parts of 200# solvent oil. The invention also discloses a preparation method of the styrene-modified alkyd resin. The styrene-modified alkyd resin is excellent in film-forming property, high in curing speed, low in viscosity and good in solubility. The tartaric acid production wastewater is adopted, so that the production cost is greatly reduced, and meanwhile, the treatment problem of wastewater is also solved, energy resources are saved, waste is changed into useful materials, and the styrene-modified alkyd resin is safe and environment-friendly; the styrene-modified alkyd resin is excellent in film-forming property, high in cross-linking reaction activity, high in curing speed, low in viscosity and good in solubility and also has high hardness, and excellent water resistance and alkali resistance.

Description

technical field [0001] The invention relates to the technical field of alkyd resins, in particular to a styrene-modified alkyd resin and a preparation method thereof. Background technique [0002] Alkyd resin is mainly used in paints and coatings, and is widely used in metal protection, furniture, vehicles, construction, etc. It can also be used as the insulating layer of enameled wires, and the ink made into it is widely used in the printing industry. In addition, it is also used in the manufacture of molded plastics . Alkyd resin is the main film-forming substance of traditional blending paints and enamel paints. It has the characteristics of good weather resistance, good adhesion, brightness and fullness, and is convenient for construction. Dry enamel, primer, topcoat and varnish are widely used in the coating of buildings such as bridges and machinery, vehicles, ships, aircraft and instruments. [0003] At present, in order to reduce costs, most processes use PTA waste...
