Problems solved by technology

Vegetable oil is introduced into unsaturated polyester resin through chemical reaction, which easily causes the polymerization reaction of vegetable oil itself, which makes the modification effect limited. Vegetable oil can also modify unsaturated polyester resin by blending method. Due to the poor compatibility of the two, resulting in modification that does not achieve the desired effect

Abstract

The invention discloses a flat paint for furniture. The flat paint is composed of the following raw materials (by weight): 1.4-3 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 0.7-2 parts of PTMEG, 0.8-2 parts of p-toluenesulfonamide, 10-12 parts of tung oil, 0.06-0.07 part of sodium hydroxide, 3-4 parts of methanol, 0.1-0.2 part of perfluorosulfonate resin, 6-8 parts of acetic acid, 10-15 parts of 26-30% hydrogen peroxide, 10-17 parts of tetraethyl orthosilicate, 0.1-0.2 part of Y-chloropropyltrimethoxysilane, 70-80 parts of unsaturated polyester resin, 0.6-1 part of methylethyl ketone peroxide, 15-20 parts of barite powder, 1-2 parts of naphthenic soap, 0.8-2.2 parts of lauryl alcohol phosphoric acid ester potassium, 1-2 parts of phenylimidazoline, 0.8-1 part of calcium alginate, 3-5 parts of titanium dioxide and 0.2-0.4 part of polyoxyethylene octylphenol ether. By adding titanium dioxide and barite powder into the paint, effective effects can be achieved, and decorative performance of a film is enhanced.

Description

technical field [0001] The invention relates to the technical field of furniture coatings, in particular to a matting coating for furniture and a preparation method thereof. Background technique [0002] Saturated polyester resin is one of the film-forming resins commonly used in the preparation of coatings. However, when the general-purpose unsaturated polyester resin is used to prepare coatings, there are disadvantages such as poor water resistance, solvent resistance, heat resistance, and poor mechanical properties. Modification of ester resin to improve its comprehensive performance At present, polyurethane or polyurethane prepolymer, acrylic resin, epoxy resin, silicone, nanomaterials and vegetable oil are mainly used to modify unsaturated polyester resin in order to improve its preparation. performance when coating. Among them, vegetable oil modified unsaturated polyester resin has attracted more and more attention. Vegetable oil is introduced into unsaturated polyes...
