Description
Technical field
The present invention relates to the insullac technical field, be specifically related to a kind of production method of epoxy resins insulation lacquer.
Background technology
At present, insullac is indispensable insulating material in motor and the electrical apparatus industry, and traditional insullac all can give out harmful gas in transportation, and then cause the disadvantageous effects such as human body skin allergy, giddy, septicemia, in mishandling situation, lead to easily serious environmental influence accident.There is following shortcoming in existing insullac simultaneously: 1, in actual production process, production technique is comparatively complicated, and the production process power consumption is large, and preparation cost is higher; The hot dielectric loss of 2, coating with lacquer in application is bigger than normal, and curing dimensional contraction rate is bigger than normal.
Summary of the invention
The production method that the purpose of this invention is to provide the epoxy resins insulation lacquer that a kind of production technique is simple, use properties is good and safe and reliable.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: a kind of production method of epoxy resins insulation lacquer, comprise A component and B component, and the production method of described epoxy resins insulation lacquer may further comprise the steps:
(1), A component: by weight ratio Resins, epoxy is moved in the reaction ax, add simultaneously a certain amount of properties-correcting agent, stir and be warming up to 60～120 ℃, be incubated 2～5 hours, the cooling discharging can obtain the A component;
(2), B component: by weight ratio methyl tetrahydro phthalic anhydride is moved in the reaction ax, add simultaneously a certain amount of properties-correcting agent, stir and be warming up to 60～120 ℃, be incubated 2～5 hours, the cooling discharging can obtain the B component;
(3), A component and B component stirred be mixed, obtain the epoxy resins insulation lacquer.
Further, described properties-correcting agent is thiorubber, polyamide resin, polyvinyl alcohol uncle butyraldehyde, paracril class, resol class or vibrin.
The present invention has following beneficial effect: the production method of a kind of epoxy resins insulation lacquer of the present invention, comprise A component and B component, and its production method is: one, A component: take Resins, epoxy as raw material, and add a certain amount of properties-correcting agent, thereby can make the A component; Two, B component: with the methyl tetrahydro phthalic anhydride raw material, add a certain amount of properties-correcting agent, thereby can make the B component; Three, A component and B component are stirred be mixed, obtain the epoxy resins insulation lacquer; Wherein, properties-correcting agent is thiorubber, polyamide resin, polyvinyl alcohol uncle butyraldehyde, paracril class, resol class or vibrin, and adopts above-mentioned properties-correcting agent can improve shock strength, the cementability of product, and can improve heatproof and corrosion resistance nature.The present invention adopts aforementioned production method, and electric property, resistance toheat, the mechanical property of the epoxy resins insulation lacquer that it makes all reach good application characteristic, and safe and reliable, are widely used in motor and electrical apparatus industry.In addition, the present invention has the characteristics such as production technique is simple, cost.
