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 an aluminum sol furniture coating, which is composed of the following raw materials: calcium chloride, aluminium isopropoxide, N-ethyl-p-toluenesulfonamide, diphenyl methane diisocyanate, tung oil, sodium hydroxide, methanol, perfluorosulfonate resin, acetic acid, 26-30% hydrogen peroxide, tetraethyl orthosilicate, Y-chloropropyltrimethoxysilane, unsaturated polyester resin, methylethyl ketone peroxide, montmorillonite powder, tert-butylhydroquinone, stearic acid, phthalic anhydride, benzyltrimethylammonium chloride, fatty alcohol polyoxyethylene ether ammonium sulfate and a cross-linking agent taic. By using aluminium isopropoxide as an aluminium source, the obtained aluminium sol can effectively improve compatibility of all the raw materials, and stability strength of a film of the finished product is boosted.

Description

technical field [0001] The invention relates to the technical field of furniture coatings, in particular to an aluminum sol furniture coating 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 poly...
