AI Technical Summary
Technical Problem
It is difficult to prepare reactive diluent coatings with good rigidity, hardness and flame retardant effects using tung oil as raw material.
Method used
The active diluent of methyl tung acid is prepared by reacting tung oil with methanol, tetrahydrofuran and other substances, and combined with components such as epoxy resin, flame retardant polysiloxane curing agent, to form components A and components B. By mixing the molar ratio of epoxy groups and acid anhydride groups, a coating containing a reactive diluent is prepared.
Benefits of technology
The coating has achieved good rigidity, hardness and flame retardant effects, and the raw materials are green and environmentally friendly, and there is no organic volatile gas production.

Abstract
The invention discloses a coating containing a reactive diluent and a preparation method thereof, and relates to the technical field of polymer materials. When preparing the coating containing the reactive diluent, the present invention performs cycloaddition of methyl eleostearate and fumaric acid, and then reacts with epichlorohydrin to obtain the methyl eleostearate reactive diluent; DOPO and methylvinyldiethoxysilane are reacted to obtain a flame retardant silane monomer; the flame retardant silane monomer, hydroxymethyltriethoxysilane, and dimethyldiethoxysilane are hydrolyzed and self-polymerized, and ethoxytrimethylsilane is used to end-cap to obtain a flame retardant polysiloxane; the flame retardant polysiloxane and chlorinated trimellitic anhydride are reacted to obtain a flame retardant polysiloxane curing agent; epoxy resin and methyl eleostearate reactive diluent are mixed into component A, and the flame retardant polysiloxane curing agent and 2-ethyl-4-methylimidazole are mixed into component B, and the coating containing the reactive diluent is obtained. The coating containing the reactive diluent prepared by the present invention has excellent impact protection effect and flame retardant performance.
