Abstract
The invention discloses a synthesis process of high-toughness epoxy vinyl ester resin. On the basis of an existing technology of ring-opening esterification between organic unitary unsaturated carboxylic acid and epoxy resin, organic saturated binary carboxylic acid (adipic acid or sebacic acid) and a carboxyl-terminated liquid nitrile rubber (with the acrylonitrile content of 10-26%) flexible group are introduced, so that the toughness of the resin is greatly enhanced, the elongation at break of a casting body of the resin is 8-16%, and the impact strength is up to 20-30 KJ/m<2>. The synthesis process can meet special requirements of industrial production of fiber reinforced plastic. The invention synthesis process is simple, and environment-friendly and avoids generation of 'three wastes'; the product stability is high.
Description
Technical field
The invention belongs to technical field of chemical synthesis, be specifically related to a kind of high toughness epoxy vinyl ester resin synthesis technique.
Background technology
Vinyl ester resin is obtained by open loop addition chemical reaction by epoxy resin and methacrylic acid.It preserves the basic segment of epoxy resin, have again the good process performance of unsaturated polyester resin, after it solidifies under optimum conditions, show the premium properties that some is special.In the synthesis process method of current epoxy vinyl ester resin, synthetic method is too single, technical process is not easy to implement, the epoxy vinyl ester resin finished product purity generated is low, reactant per pass conversion is low, production process is complicated, and production efficiency is low and cost is high, is not suitable for scale operation.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, a kind of high toughness epoxy vinyl ester resin synthesis technique is provided, the present invention not only production process simple, increase work efficiency, and the high and superior performance of epoxy vinyl ester resin yield generated, be applicable to suitability for industrialized production.
High toughness epoxy vinyl ester resin synthesis technique provided by the invention, comprises the following steps:
(1) batching is for subsequent use with mass percent formula batching: A. bisphenol A type epoxy resin 30% ~ 50%B. organic mono unsaturated carboxylic acid 6% ~ 10%C. organic saturated dicarboxylic acid 7% ~ 12%D. end carboxyl liquid nitrile rubber 3% ~ 8%E. catalyzer 0.05% ~ 0.25%F. stopper 0.01% ~ 0.05%G. crosslinkable monomers 30% ~ 45%;
(2) drop into A, B, C, D, E and F in esterification by ring opening reaction response device, stir when passing into nitrogen, be warming up to 140 ~ 170 DEG C gradually, reaction system become all even transparent after be incubated 2 ~ 3h again, until record acid number to be less than 40mgKOH/g;
(3) dilution is cooled to less than 110 DEG C and adds G, fully stirs;
(4) filtration is cooled to room temperature, filters and obtain light yellow muddy viscous liquid.
High toughness epoxy vinyl ester resin synthesis technique provided by the invention, its beneficial effect is, overcoming prior art, to prepare operation in epoxy vinyl ester resin technological process more, and the problem that workload is large, improves working efficiency; Substantially increase the transformation efficiency of reactant and the productive rate of product.
Embodiment

Embodiment
The high toughness epoxy vinyl ester resin synthesis technique of the present embodiment, comprises the following steps:
(1) batching is for subsequent use with mass percent formula batching: A. bisphenol A type epoxy resin 50%B. organic mono unsaturated carboxylic acid 510%C. organic saturated dicarboxylic acid 10%D. end carboxyl liquid nitrile rubber 8%E. catalyzer 0.25%F. stopper 0.05%G. crosslinkable monomers 31.7%;
(2) drop into A, B, C, D, E and F in esterification by ring opening reaction response device, stir when passing into nitrogen, be warming up to 170 DEG C gradually, reaction system become all even transparent after be incubated 2 ~ 3h again, until record acid number to equal 30mgKOH/g;
(3) dilution is cooled to 100 DEG C and adds G, fully stirs;
(4) filtration is cooled to room temperature, filters and obtain light yellow muddy viscous liquid.
High toughness epoxy vinyl ester resin synthesis technique, without the need to loaded down with trivial details post-reaction treatment, operation simple possible, reduces process costs greatly, and environmentally friendly pollution-free, and technical process is easy to implement, achieves the suitability for industrialized production of product.
