The application such as products of sticky agent of building coating, glue, rubber undergoes the test of natural climate at outdoors environment, if be destroyed integratedly what cause illumination, cold heat, harships, and appear fade, become angry, chap, the demote below pulverization and intensity the is material “ that the phenomenon of a series of ageing is weighed is able to bear or endure problem of the ” that await a gender, the existence of these problems brought the earth to affect to the service life of material. Epoxy resin regards 3 big heat as one of solid sex colophony, applied domain is numerous, face be able to bear or endure industry of the problem that await a gender often have the aid of adds smooth stabilizing agent and antioxidant to come to those who raise common epoxy resin be able to bear or endure await a gender. But these methods often take temporary solution not effect a permanent cure, the most essential settlement train of thought still wants from resinous structure proceed with, await function through introducing saturated framework structure to raise resinous to be able to bear or endure, fat annulus a group of things with common features the emerge as the times require such as epoxy resin of A of double phenol of epoxy resin and hydrogen sulfide, among them double phenolic A epoxy resin has hydrogenation similar the solidify function of double phenolic A epoxy resin, and hold concurrently be able to bear or endure goodly await a gender.
Epoxy resin of A of hydrogenation double phenol is at first by Japan east change waited for an enterprise to come true to commercialize. At present the main brand on market has Epalloy5000, AL-3040, ST-3000, EP-4080, YDH3000, EX-252, XY518, JH3000 to wait, typical target sees next tables.
Technology of production of epoxy resin of A of hydrogenation double phenol and technology of production of epoxy resin of double phenolic A are similar, its are main process is by hydrogenation chloric propane of double phenolic A and annulus oxygen is in for main raw material, in activator (it is Lewis acid commonly, each uses activator is different) change through ether below catalysis - annulus is changed - purificatory wait for unit operation to finish preparation. (see figure below) [1-5] , but main be enslaved to be enslaved to A of double phenol of hydrogen sulfide of its raw material fails to come true tardy homebred change, it is product dimensions additionally small bring about each to produce business to be given priority to with intermittent law, rate of 3 useless control brought about on the high side of price of epoxy resin of A of hydrogenation double phenol not high to affect downstream use thereby.
In recent years as A of double phenol of hydrogen sulfide of main raw material large-scale homebred change, anhui is new the domestic company such as Jing Hong of Oliver of far, Yantai, Hubei obtains a technology to break through in succession, realized brand of series of epoxy resin of A of hydrogenation double phenol early or late commercialize production. Epoxy resin of A of hydrogenation double phenol is stuck by right of its receive strength tall, chemical stability systole of good, solidify is small, mechanical function exceedingly good, insulation property craft of good, treatment is handy wait for marked characteristic to be in glue sticky agent, the domain such as electric insulating material received relatively wide application. However of a blemish in an otherwise perfect thing is, as we have learned at present oxygen of annulus of double phenolic A all puts the major hydrogen sulfide on market in always chloric exorbitant phenomenon (＞ 15000ppm) , this satisfies its to be in hard greatly the application of electronic domain. Be aimed at this problem, taiteer began Jiangsu in March 2023 the research and development of epoxy resin of A of double phenol of electronic class hydrogen sulfide, the eligible product that the annulus combustion technology that the synthetic line that time of half an year of all previous classics tried to differ is good at finally through the company got electronic degree (analytic index sees figure below) .
Additional, also did a few initial tests to the solidify function of this annulus oxygen, function index expresses place to show as follows [6] :
