Abstract

The invention relates to an epoxy resin and a relative application. The epoxide resin comprises epoxy resin, reaction dilutent and hardener, wherein the reaction dilutent is monomer or oligomer of acrylate and methacrylate with low viscosity in the ambient temperature and at least one unsaturated double-bond reactive function group, the reaction dilutent is added in the epoxy resin and is mixed uniformly to form the main agent of the epoxy resin formulation, the main agent comprises the reaction dilutent of 5-30 parts and agent B formed by the hardener, the weight percentage of the agent B and the main agent crystal is 20-50:100. The invention can improve the gelatinizing time, the exothermic peak temperature and the processing operation character of viscosity in the hardening process of the epoxy resin, which reduces the mechanical properties of the cured epoxide less, improves the tenacity of the epoxide, is suitable for manufacturing structural element of large scale composite material (air vane, craft, car and aerial craft and the like), and has good operation time, low exothermic peak temperature and fiber immersing property.

Description

technical field [0001] The present invention relates to an epoxy resin, in particular to an epoxy resin that can significantly prolong the gel time (Geltime) during the hardening reaction without greatly reducing the mechanical properties of the epoxy resin and its application. Background technique [0002] The invention of epoxy resin has gone through a long period of time, and its industrial production and application are only in recent years. Two major discoveries at the end of the nineteenth century and the beginning of the twentieth century opened the curtain of epoxy resin. In 1891, Lindmann in Germany reacted hydroquinone and epichlorohydrin to form a resinous product. In 1909, Russian chemist Prileschajew discovered the reaction of anisole peroxide and olefins. Epoxy compounds can be generated, and these two chemical reactions are still the main pathways in the synthesis of epoxy resins. [0003] In 1938, Pierre Castan of Switzerland filed a patent application for t...
