Abstract

The invention provides water-borne acrylic-modified alkyd resin emulsion which comprises the following components in percentage by weight: 15-25% of polyester modified alkyd resin, 10-20% of a glycol ether solvent, 5-20% of a propylene glycol ether solvent, 0-5% of n-butanol, 5-8% of vinyl monomer, 15-25% of acrylic monomer, 2-6% of BPO, 4-7% of organic amine and 21% of deionized water, wherein the polyester modified alkyd resin comprises the following components: 12-20% of rosin, 22-30% of unsaturated fatty acid, 25-35% of polyester, 3-8% of diethylene glycol, 1-5% of pentaerythritol, 7-12% of maleic anhydride, 3-10% of xylene, 0.5-2.5% of sodium hydrogen sulfite and 10% of a glycol ether solvent and a propylene glycol ether solvent. Compared with the prior art, the water-borne acrylic-modified alkyd resin emulsion has the benefits of higher environment friendliness and better water solubility.

Description

【Technical field】 [0001] The invention relates to the technical field of coatings, in particular to a water-based acrylic modified alkyd resin emulsion and a preparation method thereof. 【Background technique】 [0002] Polyester is currently the largest and most widely used synthetic fiber variety in the world, accounting for more than 60% of the world's synthetic fiber output. It is widely used in the production of clothing, bedding, decorative fabrics, special fabrics and other textiles or other industrial fiber products. The rapid development of the polyester industry has brought huge economic value, but polyester is difficult to degrade in the natural environment, and the continuous increase of waste polyester has brought enormous pressure to the natural environment. [0003] Alkyd blending paint and alkyd antirust paint prepared with alkyd resin have appeared in the related art using waste polyester as raw material, using acid hydrolysis to degrade waste polyester to pr...
