Abstract
The invention discloses modified epoxy resin which consists of epoxy resin, a curing agent, a flexibilizer, a thermal stabilizer, a filling reinforcing agent, an anti-impact modifier, a crosslinking agent and the like. By virtue of the different additives, the toughness, the intensity, the fatigue resistance of the modified epoxy resin can be improved, and the comprehensive performance of the epoxy resin is greatly improved. Due to the low cost of the modified epoxy resin, the use range of the modified epoxy resin can be greatly expanded, and the modified epoxy resin is particularly applicable to the field of electronic and electrical insulating materials.
Description
Technical field
The present invention relates to field of compound material, particularly relate to a kind of modified epoxy and application thereof.
Background technology
Epoxy resin is the most widely used matrix resin of polymer matrix composite.Be widely used because epoxy resin has the excellent feature such as adhesiveproperties, erosion resistance, mechanical property, chemical stability, easy-formation processing.In fields such as coating, light industry, building, machinery, space flight and aviation.But because after epoxy resin cure, cross-linking density is high, exist internal stress greatly, easy crisp, the defect such as resistance to fatigue is low, thermotolerance is low, poor impact resistance, make it be difficult to meet the eyeball of engineering, make it apply and be very restricted.
So be the primary study direction of current epoxy resin Application Areas to the modification work of epoxy resin.And in the modification of epoxy resin toughness reinforcing be improve its application very important part.There is heat-resistant powder filler toughness reinforcing in current prior art, the methods such as thermotropic liquid crystal polymer toughening, research at present for toughening modifying is mainly concentrated both ways: be how to obtain high performance modified epoxy on the one hand, to meet the needs in market and actual industrial production; Be the modified epoxy how obtaining low cost on the other hand, put into production in large quantity with scientific research and apply.
Summary of the invention
In order to solve the technological deficiency existed in above-mentioned prior art, the present invention proposes that a kind of cost is low, toughness significantly improves, mechanical property is good, physical strength is high, excellent combination property and can carry out the modified epoxy of large quantities of input industrial production and application, also has its application in electric insulating material field.
Technical scheme of the present invention is as follows:
A kind of modified epoxy, is formed by following composition and weight ratio proportioning:
Wherein toughner is the mixture of one or more in polyethersulfone, polyetherimide, polyetherketone, polyphenylene oxide.
Preferably, modified epoxy is formed by following composition and weight ratio proportioning:
Preferably, solidifying agent is the mixture of one or more compositions in glyoxaline compound, tertiary amine compound or organic phosphine compound.
Preferably, toughner is one or both mixture of polyetherimide, polyetherketone.
Preferably, thermo-stabilizer is dibasic lead stearate.Thermo-stabilizer can stop effectively, reduce the degraded even substantially stopping epoxy resin, thus extends its work-ing life.Therefore thermo-stabilizer has vital role for the over-all properties of modified epoxy, and preferred dibasic lead stearate can play good effect.
Preferably, packing strengthening agent is talcum powder.Weighting agent can improve the mechanical property of epoxy resin effectively, and reaches by the reaction conditions reducing reactant the object that a low consumption completes modifying process.Therefore the over-all properties for modified epoxy has vital role, and preferred talcum powder can reduce the reaction cost of this modified epoxy effectively.
Preferably, anti-impact modifier is chlorinatedpolyethylene.Anti-impact modifier can improve the low temperature brittleness of epoxy resin well, improves the toughness of epoxy resin.So anti-impact modifier has vital role for the performance of modified epoxy.Preferred chlorinatedpolyethylene can improve the toughness of epoxy resin effectively.
Preferably, linking agent is dicumyl peroxide.Linking agent, as the one of additive, can improve other over-all propertieies such as the thermotolerance of epoxy resin, oxidation-resistance, dimensional stability and mechanical property effectively significantly.Preferred dicumyl peroxide can improve the over-all properties of epoxy resin effectively.
Another goal of the invention of the present invention is the application of above-mentioned modified epoxy in electric insulating material field.
Effective effect of the present invention is:
The first, modified epoxy provided by the present invention, by using epoxy resin as matrix, add the modification that the additives such as solidifying agent, toughner, thermo-stabilizer promote epoxy resin wherein, greatly strengthen the toughness of epoxy resin, intensity, antifatigue degree, shock-resistant degree etc., substantially increase the over-all properties of epoxy resin.
The second, modified epoxy provided by the present invention, except the lifting in mechanical property, low its use range that also makes of the cost of its modification can be expanded greatly, application especially in the industrial production.
Three, modified epoxy provided by the present invention is in the application in electric insulating material field, because modified epoxy provided by the present invention is greatly improved in mechanical property, toughness, intensity, antifatigue degree, shock-resistant degree etc., make it particularly outstanding in the lifting of the application in electric insulating material field.
