Abstract
The invention discloses a waterborne alkydemulsion, a waterborne alkydvarnish and a waterborne alkyd color lacquer and a preparation method of the waterborne alkyd emulsion. The waterborne alkyd emulsion is prepared from the following raw materials in percentage by mass: 40-60% of alkyd base resin, 2-5% of alkali compounds, 2-5% of a YX-001 non-ionic emulsifier, 2-5% of a YX-002 anionic emulsifier and 25-54% of deionized water, wherein the alkyd base resin is prepared from the following raw materials in percentage by mass: 30-40% of soya oil acid, 3-9% of hyperbranched polyhydric alcohols, 3-8% of trimethylolpropane, 10-18% of pentaerythritol, 4-9% of benzoic acid, 2-5% of rosin, 15-20% of phthalic anhydride, 5-10% of phthalic anhydride and 3-8% of xylene. The waterborne alkyd varnish and the waterborne alkyd color lacquer are prepared from the waterborne alkyd emulsion. The waterborne alkyd emulsion has uniform and narrow particle size distribution, is not layered after being stored at normal temperature for one year, is not demulsified when stirred at a high speed of 400r / min at 0 DEG C and has relatively high cost performance; in addition, the preparation method is simple and the applicability is wide.
Description
technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a preparation method of a water-based alkyd emulsion and a method for preparing a water-based alkyd varnish and a water-based alkyd paint with the emulsion. Background technique [0002] Now on the market are solvent-based alkyd resins and paints and varnishes, which pose a great threat to human health and environmental pollution; there are no alkyd paints and varnishes prepared on the basis of water-based alkyd emulsions. [0003] At present, the preparation of emulsions is mainly based on acrylic acid or epoxy modified alkyd, which has relatively high cost and technical requirements, and the production process is complicated, which cannot meet the user's requirements for high cost performance. Contents of the invention [0004] The purpose of the present invention is to provide a water-based alkyd emulsion, which solves the problems of the existing alkyd emulsion ...
