Epoxy resin is a kind of important chemical, apply extensively at the domain such as material of sticky agent of coating, glue, electron, composite material. Its unique chemical structure and property make it has exceedingly good physics mechanical function, good be able to bear or endure chemistry and high temperature resistant function, and stick exceedingly goodly receive function and corrosion resistance can. The article will be mixed from the main character of epoxy resin the structure is analytic two respects begin, introduce the ABC of epoxy resin in detail. One, the physics with the main good character of epoxy resin is mechanical function epoxy resin by annulus oxygen former aggregate and into, many annulus oxygen is contained in the element base (- O-CH2-CH-) , these annulus oxygen radical is OK as luscious as other active group (wait like amine, phenol) reaction makes three-dimensional polymer, form structure of high polymer network, make mechanical function intensity and tenacity raise its physics considerably thereby. In the meantime, epoxy resin element is very easy also wait with all sorts of plasticizer, auxiliary mix, form the stuff that has different thing sex and function. Be able to bear or endure goodly slue annulus oxygen is contained in element of chemical function epoxy resin base, in temperature on the high side or active when the bigger that fight dissolve happen not easily also rupture, consequently its colophony is able to bear or endure in convention good chemical stability and corrosion resistance are had below chemical operation condition.
The different strong toughness that good heat-resisting function epoxy resin can realize its place to need through allocating different stiffening agent, model is measured and the reason of of all kinds content such as hot property pledges, this makes it shows scene in high temperature environment. In the meantime, after solidify, as a result of the bridge-type structure in epoxy resin element, its are handed in each other between the element of long chain tangle and appear piece quite the bate behavior of degree, improved its hear resistance and mechanical performance further. Stick exceedingly goodly because epoxy resin is kino of a kind of blame,receive performance, the dispersive agent that different sort can add in cause mixture course improves coating shedding to extend character and adherent to basic level power; This explicit and a lot of glue is having wide application in sticky agent domain, if spare parts of glue of glass reinforced plastics, car, solder is nodded,wait. 2, the structure of epoxy resin is analytic epoxy resin is by annulus oxygen base (- O-CH2-CH-) composition, the element measures size to differ, but wait for scent a group of things with common features and carbolic annulus to connect to receive and come by benzene annulus, heat-resisting was formed after solidify, be able to bear or endure sclerotic and caky three-dimensional polymer network.
In epoxy resin, oxygen atom is located in colophony element advocate near catenary extreme, also call “ active intermediate body ” or “ annulus oxygen radical ” . Oxygen radical ” has these “ link very fast response is active, can with a variety of luscious groups (wait like amine, phenolic, alcohol) produce condensation reaction to make epoxy resin. In addition, its annulus oxygen base still can wait with a variety of acid anhydride, chloride produce annulus to open reaction preparation to give all sorts of function sexes epoxy resin material. Common epoxy resin includes double phenolic A epoxy resin, annulus oxygen propane epoxy resin to wait. Anyhow, epoxy resin regards a kind of main base as chemical, had been applied extensively at a lot of domains such as material of industry, civil coating, electron. As people characteristic to material make a thorough inquiry is ceaseless and thorough, the function of epoxy resin also is in be perfected ceaselessly and rise. To manufacturing company, want job of research and development of resinous of beaded finish oxygen, ability drives the further progress of epoxy resin material and application.
