Embodiment Construction

[0020] The epoxy resin coating toughened by epoxy-terminated polybutadiene rubber of the present embodiment is prepared by the following steps:

[0021] (1) Use sodium hydroxide solution to adjust the pH of formaldehyde to 8-9, add phenol, heat to 50°C and stir to dissolve all the phenol; add carbon fiber, raise the temperature to 90°C and stir for 10 hours, then raise the temperature to Add triphenyl phosphate at 110°C, stir and react at constant temperature for 5 hours, raise the temperature to 120°C to remove unreacted monomer and moisture in a vacuum; dry to obtain activated carbon fiber; among them, the mass of formaldehyde, phenol, carbon fiber and triphenyl phosphate The ratio is 1:1.1:0.5:0.8;

[0022] (2) Add cyclohexane, toluene and butadiene into the reaction kettle at a mass ratio of 1:0.15:0.15, mix and stir evenly, place in a constant temperature water bath at 55°C, add tetramethylethylenediamine and n-butyl Lithium, stirring and polymerizing at constant tempera...

Abstract

An epoxy group terminated and polybutadiene rubber toughened epoxy resin coating is characterized in that firstly, formaldehyde, phenol and triphenyl phosphate are subjected to a mutual crosslinking reaction to coat carbon fiber, and activated carbon fiber is obtained; then, butadiene is polymerized under the catalytic action of n-butyllithium, glycidyl methacrylate is used as the terminal, and epoxy group terminated polybutadiene rubber is obtained; finally, epoxy resin is modified with the epoxy group terminated polybutadiene rubber and filled with the activated carbon fiber and organosilicone modified anti-ultraviolet particles. During usage, the epoxy resin coating is mixed with a curing agent, spraying and drying are performed, and the epoxy group terminated and polybutadiene rubber toughened epoxy resin coating is obtained. The coating has the advantages of high hardness, high adhesion, excellent flexibility, good wear resistance, ultraviolet resistance, low film forming temperature, high gloss, high drying speed at the normal temperature, good film leveling property and the like.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an epoxy resin coating toughened by epoxy-terminated polybutadiene rubber and a preparation method thereof. Background technique [0002] Epoxy resin has the advantages of excellent bonding performance, wear resistance, electrical insulation performance, mechanical performance, chemical stability, good processing performance, low shrinkage and low cost, so it is widely used in various fields of the national economy. Applications, such as adhesives, electronic instruments, construction, aerospace, coatings and advanced composite materials and other fields. However, the cross-linking density of epoxy resin is high after curing, and there are more rigid groups in the epoxy resin structure, which produces strong internal stress during curing and poor impact resistance. Therefore, it is necessary to toughen the epoxy resin. [0003] Epoxy resins are usually toughened with rubber, thermoplasti...
