Abstract
The invention discloses a curing agent which is composed of the following components in percentage by mass: 41-45% of benzyl alcohol, 28-32% of isophorone diamine, 18-22% of EP-16 epoxy resin, 3-7% of triethanolamine, 0.5-1.5% of antioxidant V76-P and 0.5-1.5% of ultraviolet absorbent UV-329. The preparation method comprises the following steps: adding the benzyl alcohol and isophorone diamine into a reaction kettle, stirring, adding the EP-16 epoxy resin into the reaction kettle, stirring, sequentially adding the triethanolamine, antioxidant V76-P and ultraviolet absorbent UV-3292, and heating the reaction kettle to 70 DEG C; and after the reaction finishes, cooling to 25 DEG C, and subpackaging. The curing agent has the advantages of low yellowing tendency and the like.
Description
Technical field
The present invention relates to a kind of solidifying agent and preparation method thereof, be applied to the preparation field of solidifying agent.
Background technology
Epoxy resin is the important thermosetting resin of a class, be widely used in the purposes such as tamanori, coating, also known as making Albertol, artificial resin, Resin adhesive etc., artificial resin is thermoset epoxies polymkeric substance, and most people molding resins produces chemical reaction by epichlorohydrin and dihydroxyphenyl propane (phenol methane) and forms, in the preparation process of epoxy resin, need to use solidifying agent, but existing solidifying agent easily turns to be yellow, the therefore very large preparation that have impact on epoxy resin.
Summary of the invention
The present invention is for avoiding the weak point that exists in above-mentioned prior art, providing a kind of solidifying agent and preparation method thereof, to solve the problems such as existing solidifying agent easily turns yellow.
The present invention be technical solution problem by the following technical solutions:
The invention discloses a kind of solidifying agent, according to mass percent, composed of the following components: phenylcarbinol 41%-45%, isophorone diamine 28%-32%, EP-16 epoxy resin 18%-22%, trolamine 3%-7%, oxidation inhibitor V76-P 0.5%-1.5%, UV light absorber UV-329 0.5%-1.5%.
As preferably, solidifying agent of the present invention, according to mass percent, composed of the following components: phenylcarbinol 43%, isophorone diamine 30%, EP-16 epoxy resin 20%, trolamine 5%, oxidation inhibitor V76-P 1%, UV light absorber UV-3292 1%.
Further, solidifying agent of the present invention, concrete preparation method is as follows: according to above-mentioned mass percent, phenylcarbinol and isophorone diamine are joined in reactor, stir, after stirring, EP-16 epoxy resin is joined in reactor, then stirs, after stirring, add trolamine, oxidation inhibitor V76-P, UV light absorber UV-3292 more successively, reactor is heated to 70 DEG C, then keep 70 DEG C, react 1 hour, after having reacted, be cooled to 25 DEG C, subpackage.
Owing to adopting technique scheme, solidifying agent of the present invention and preparation method thereof is by adding oxidation inhibitor V76-P 1% and UV light absorber UV-3292, oxidation inhibitor V76-P is the composite Effective Anti xanthochromia agent of major-minor oxidation inhibitor, be mainly used in epoxy systems, antioxidant and the photo and thermal stability of product can be improved, therefore the defect turned yellow because of oxidation can effectively be prevented, UV light absorber UV-3292 can absorb ultraviolet effectively, prevent the xanthochromia because of uviolizing, in addition, oxidation inhibitor V76-P 1% uses together with UV light absorber UV-3292, a synergistic effect can be played, better effects if.
