Abstract

The invention discloses tung oil modified organic silicon multifunctional coating and a preparation method thereof. The coating is prepared by or the preparation method comprises the following steps:firstly preparing resin and then preparing the coating. The preparation method of the resin comprises the following steps: adding dodecene and triethoxysilane into a four-neck flask, starting mechanical stirring, with a condensate being orange non-transparent liquid at this moment, heating with an oil bath, removing moisture in raw materials, feeding high-purity nitrogen, heating, adding a chloroplatinic acid isopropanol solution, reacting, adding tung oil, reacting, removing small molecules, performing vacuum release, cooling and discharging to obtain resin; sealing and storing the coating. The resin for the coating is prepared by selecting one of four preparation methods. The coating is obtained by reacting dodecene, triethoxysilane and tung oil under the catalysis of chloroplatinic acid. Due to the excellent molecular structure, the adhesive force is good. The multifunctional coating has the advantages of low surface tension, favorable corrosion resistance, favorable rust resistance, favorable fog resistance and favorable water resistance, has wide application range, and can be widely used in severe environments.

Description

technical field [0001] The invention relates to an organosilicon multifunctional paint, in particular to a tung oil modified organosilicon multifunctional paint, which belongs to organosilicon materials. The invention also relates to a preparation method of the tung oil modified organosilicon multifunctional coating. Background technique [0002] Tung oil is a natural dry vegetable oil produced by pressing the seeds of tung oil. It has the characteristics of fast drying, low density, good gloss, strong adhesion, heat resistance, acid resistance, alkali resistance, corrosion resistance, rust resistance, and non-conductivity. my country has a large amount of tung oil resources, but the utilization technology of tung oil is relatively low. The main applications of tung oil are in anti-corrosion coatings, ink additives, rust prevention of steel, and insulating paint for coils. Tung oil is a mixture that contains tungoleic acid, the structure of which is shown in the following f...
