Abstract
The invention discloses a preparing method of continuous insulation dipping former plastic, which comprises the following steps: (1) stirring and dispersing ethane group ester resin, low-shrinkage additive, diluent, trigger, defoaming wetted agent, viscosity reduction wetted agent, aluminum hydroxide and releasing agent; producing resin paste; (2) pumping into mixing chamber; pumping thickener and color into mixing chamber continually at the same time; mixing evenly; producing mixture; (3) leading into glass fiber continuance dipping device; adding into alkali-free short cutting glass fiber; getting the product. The product possesses good quality, which can be used to high and low electric appliance of electric industry and raw materials for production of bumper.
Description
(1) technical field
The present invention relates to a kind of method of preparation engineering plastics.Be the preparation method of continuous insulation dipping former specifically.The moulding compound of Sheng Chaning is applicable to also to can be used as the raw materials for production of bumper on the high and low voltage electrical equipment of electric utility in this way.
(2) background technology
In electric utility, used insulating material mainly is plastics on the high and low voltage electrical equipment at present.This insulating material mainly is to be main raw material with unsaturated polyester resin, packing material, thickening with the alkali-free short glass fiber, is equipped with auxiliary materials such as low shrinkage additive, initiator, thickening material, releasing agent again and makes.Its production method is after earlier unsaturated polyester resin, packing material, low shrinkage additive, initiator, thickening material and releasing agent being mixed together, to mix, soak into the alkali-free short glass fiber again.Because thickening material wherein mixes with other raw material at the very start, mix the back and just begun to play local thickening power, and can thickening gradually in whole process of production.When this thicker compound mixes with the alkali-free short glass fiber, be difficult to fine infiltration between itself and alkali-free short glass fiber, regular meeting occurs with in a collection of insulating material, produce earlier and after the quality produced inconsistent, make quality product relatively poor.
(3) summary of the invention
The problem to be solved in the present invention provides a kind of preparation method of continuous insulation dipping former.The moulding compound of producing in this way, quality is better.
For addressing the above problem, the present invention takes following technical scheme:
Preparation method of continuous insulation dipping former of the present invention, contain following steps successively:

(2) then, pour into vinyl ester resin, low shrinkage additive, thinner, initiator, froth breaking treating compound, viscosity reduction treating compound, aluminium hydroxide and releasing agent in the beater tup together, dispersed with stirring is 9～13 minutes under 15～40 ℃ temperature, and obtaining viscosity is that 5000～15000Pas, density are the resin paste of 1.73～1.77Kg/L;
(3) afterwards, thickening material and pigment are respectively charged in two containers, are using monoblock pump with 60cm
3When the speed of/commentaries on classics pumps into mixing section uniformly and stably with resin paste, use toothed gear pump respectively with 1.32cm
3The speed and the 0.414cm of/commentaries on classics
3The speed of/commentaries on classics is with thickening material and pigment pumps into mixing section uniformly and stably simultaneously and resin paste is carried out uniform mixing, obtains compound;
(4) then, when compound being sent into glass fibre continuous impregnating device equably, add the alkali-free short glass fiber, obtain described continuous insulation dip molding material by plate valve; Wherein, said glass fibre continuous impregnating device is German S﹠amp; The glass fibre continuous impregnating device of H company exploitation.
Take such scheme, have the following advantages:
Because method of the present invention is earlier vinyl ester resin, low shrinkage additive, thinner, initiator, froth breaking treating compound, aluminium hydroxide and releasing agent to be mixed together, and makes resin paste.Then, when resin paste and pigment are continuously pumped into mixing section, also continuously add thickening material, and after adding thickening material, just mix, soak into the alkali-free short glass fiber, when compound also is able to do in time thickening, does not just mix, soak into, make and soak into well between compound and alkali-free short glass fiber with the alkali-free short glass fiber.Thereby avoided taking place, improved quality product greatly with the front and back inconsistent situation of quality in a collection of product.
