Description
Technical field
The invention belongs to epoxy curing agent field, be specifically related to a kind of terpenyl amine epoxy resin solidifying agent and its preparation method and application.
Background technology
Epoxy resin has many excellent specific properties of binding property, thermotolerance, chemical proofing, electrical characteristic etc. to many materials and other resin-phase ratios.At present, epoxy resin is mainly used in coating, in electron trade and some composite material formings.Epoxy resin this as thermoplastic linear structure, after being heated solid resin can soften, melting, become sticky state or liquid state, after liquid resin is heated viscosity reduce.After epoxy resin only adds solidifying agent, through being cross-linked to form insoluble and not molten reticulated structure macromole, just can show excellent performance.Aminated compounds is the important solidifying agent in epoxy resin compound.In epoxy curing agent, aminated compounds is the important solidifying agent in epoxy resin compound.General amine (as quadrol, diethylenetriamine, triethylene tetramine etc.) solidifying agent has the shortcomings such as volatility is large, skin irritation and respiratory tract, toxicity is large, toughness is low, intensity is low at normal temperatures and causes its use range to be restricted.Chemically carrying out modification to amine curing agent can make its volatility little, and toxicity is low, and curing speed is moderate, and ratio requirement is not strict, easily mixes, thus overcomes above-mentioned deficiency, improve the over-all properties of epoxy resin cured product with epoxy resin.
Method of modifying of current Chinese scholars Polyamines Curing Agents of Epoxy Resins and uses thereof conducts extensive research, as US Patent No. 6576794, US3128311; Chinese patent CN101679611A, CN101348562A, CN1560107A; Wherein main method of modifying is the reaction modifying etc. of the addition modification of phenol aldehyde modified, polyamine and alkene double bond, the condensation and modification of polyamine and carbonyl compound reaction modifying, polyamine and thiocarbamide, polyamine and carboxyl; But it is less at present to obtain the research of terpenyl amine epoxy resin solidifying agent to polyamine and terpenyl modification; and China has abundant terpene resource; simultaneously terpenoid has green, the advantage such as harmless, and the novelty teabag therefore developing terpenoid has very important meaning to effectively utilizing China's terpene resource and protection of the environment.
Summary of the invention
The technical problem solved: the object of the present invention is to provide a kind of terpenyl amine epoxy resin solidifying agent and its preparation method and application.The terpenyl amine epoxy resin solidifying agent that the method utilizes biomass resource terpene compound to prepare has the advantages such as nontoxic, nonirritant, composite with liquid epoxies, the hardness of curing system can be increased, can be used in epoxy coating, improve the performances such as the weathering resistance of epoxy coating.
