Abstract

The invention relates to a self-antibacterial water-based alkyd resin for color correction and a preparation method thereof. In parts by weight, the composition comprises: 10.0-22.0 parts of dry vegetable oil, 12.0-32.0 parts of organic acid anhydride, and 4.0-4 parts of hydroxyl Schiff base 8.0 parts, 8.0-25.0 parts of polyol, 4.0-10.0 parts of neopentyl glycol pivalate, 0.4-1.0 parts of antioxidant, 1.0-4.0 parts of monobutyl itaconate, 2.5 parts of dimethylol propionic acid ~5.0 parts, 8.0~16.0 parts of xylene, 3.5~10.0 parts of neutralizer, 70.0~120.0 parts of deionized water; a self-antibacterial water-based alkyd resin for color correction prepared by the present invention, compatible with water-based color essence Good capacity, can be mixed with alcohol ether solvents in any proportion, no precipitation, fast drying, good wettability to the primer, no blooming, good adhesion, and will not bite when made into a water-based color correction agent Bottom etc.

Description

technical field [0001] The invention relates to a modified water-based alkyd resin, in particular to a self-antibacterial water-based alkyd resin for color correction and a preparation method thereof, belonging to the technical field of synthetic resins. Background technique [0002] Due to the different materials of the materials themselves, when they are assembled together for color correction, the color correction effect will be inconsistent, and the wood texture will show different conditions. In order to make the painting effect more beautiful, surface coloring treatment can be used, which does not require high operation. Through Wiping, brushing, and spraying methods can be realized, and only one step is required to complete. Because color correction itself is a very complicated process, the general color correction is due to the inconsistency of the materials of the decorative panels and furniture materials, so it is necessary to carry out the bottom color correction ...
