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

Embodiment Construction

[0017] A kind of tung oil modified furniture coating, it is made up of the raw material of following weight part:

[0018] Tung oil 10, sodium hydroxide 0.06, methanol 3, perfluorosulfonic acid resin 0.1, acetic acid 6, 26% hydrogen peroxide 10, tetraethyl orthosilicate 10, Y chloropropyl trimethoxysilane 0.1, unsaturated polyester Resin 70, methyl ethyl ketone peroxide 0.6, vermiculite powder 18.

[0019] A kind of preparation method of described tung oil modified furniture paint, comprises the following steps:

[0020] (1) Add the above-mentioned methanol to tung oil, add sodium hydroxide under stirring condition, react at 37°C for 70 minutes, distill off the methanol, stand to separate layers, and wash the collected upper liquid with sulfuric acid first, and then use hot water Washing, distillation and dehydration, to obtain methyl chertate;

[0021] (2) Mix 50% of the above-mentioned methyl licate, perfluorosulfonic acid resin, and the above-mentioned acetic acid, raise ...

Abstract

The invention discloses a tung oil modified furniture coating, which is composed of the following raw materials (by weight): 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 methyl ethyl ketone peroxide and 18-20 parts of vermiculite power. Epoxidized methyl eleostearate has aliphatic long-chain hydrocarbon which can have a plastifying effect in resin and can enhance flexibility of unsaturated polyester resin.

Description

technical field [0001] The invention relates to the technical field of furniture coatings, in particular to a tung oil modified 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 ...
