Abstract

The invention discloses anacardol glycidyl ether modified aliphatic amine hardener which is synthesized by anacardol glycidyl ether and aliphatic amine, wherein the weight ratio of the anacardol glycidyl ether to the aliphatic amine is 80:60-20:40. The invention further provides a preparation method of the anacardol glycidyl ether modified aliphatic amine hardener. According to the preparation method of the anacardol glycidyl ether modified aliphatic amine hardener, the the anacardol glycidyl ether and the aliphatic amine are obtained according to the weight percentage, and then the aliphatic amine is put into a reaction still and is heated to the temperature of 55-70 DEG C, the anacardol glycidyl ether is added into the reaction still for 1-3 hours under the stirring condition of 600-800 circles / minute, and stirring and reaction are carried out for 3-4 hours, and finally the anacardol glycidyl ether modified aliphatic amine hardener is obtained. Due to the fact that the modified aliphatic amine hardener is hardener with middle and normal temperature, toxicity and volatility of the low-aliphatic amine can be effectively reduced, and various diseases, such as oil face, albefaction and darkening of film, which easily occur in an epoxy construction process can be avoided at the same time.

Description

Technical field: [0001] The invention relates to the field of organic chemistry, in particular to an epoxy resin curing agent, in particular to a cardanol glycidyl ether modified fatty amine curing agent and a preparation method thereof. Background technique: [0002] All polymer compounds containing epoxy groups in their molecular structure are collectively referred to as epoxy resins. The cured epoxy resin has good physical and chemical properties. It has excellent bonding strength to the surface of metal and non-metal materials, good dielectric properties, small shrinkage rate, good dimensional stability and high hardness. It has good flexibility and is stable to alkali and most solvents, so it is widely used in various sectors of national defense and national economy for casting, impregnating, laminating, adhesive, coating and other purposes. [0003] Aliphatic polyamines can be cured with epoxy resin at room temperature, with fast curing speed and low viscosity. They c...
