This invention can be used to high-low electrical equipment of electric industry and especially electrical apparatus insulator and insulated shield.
Description
(1) technical field
The present invention relates to a kind of engineering plastics and preparation method thereof.Be high electric strength unsaturated polyester die plastic specifically, be applicable on the high and low voltage electrical equipment of electric utility, on the high-voltage electrical equipment such as the apparatus insulator that is particularly useful for proof voltage and anti-arc stiffness are had relatively high expectations, insulating boot with flame retardant properties.
(2) background technology
In electric utility, main and ceramic material and plastics of used insulated product on the high and low voltage electrical equipment.The former is stupalith, it is aging to be difficult for, but fragile, fragile, gradually by the latter-----plastics replace.And the latter 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.The proof voltage of this plastics and arc resistance can be lower, have only 12～13kv/mm and 180s respectively.Improve its electrical strength though can improve density by the size grading of adjusting packing material, can occur that raw material respectively is separated, powder raw material combines incomplete problem with liquid starting material, the feasible product surface of producing grows dim, second-rate.Therefore, this plastic insulation goods can only be used on proof voltage and the less demanding low voltage equipment of anti-electric arc, and can not be used on the high-voltage electrical equipments such as apparatus insulator that proof voltage and anti-arc stiffness are had relatively high expectations, insulating boot, the scope of application is restricted.
(3) summary of the invention
The problem to be solved in the present invention provides a kind of high electric strength flame-proof continuous insulation dip molding material.This high electric strength flame-proof continuous insulation dip molding material, proof voltage intensity is higher, and the scope of application is wider.
For addressing the above problem, the present invention takes following technical scheme:
High electric strength flame-proof continuous insulation dip molding material of the present invention contains the raw material of following parts by weight: 120～140 parts of 60～70 parts of unsaturated polyester resins, 30～40 parts of low shrinkage additives, 170～190 parts in aluminium hydroxide, 3～7 parts of thinners, 0.7～1.3 part of initiator, 3～5 parts of releasing agents, 1.3～1.7 parts of viscosity reduction treating compounds, 0.3～0.7 part of rheological agent, 1～3 part of thickening material, 7～13 parts of pigment and alkali-free short glass fibers.
Wherein: unsaturated polyester resin is the metaphenylene vibrin; Low shrinkage additive is to be that 55～65% monomer styrene solution dissolves and gets with commercial polysterol and concentration, and wherein, polystyrene accounts for 35～45 weight %, and monomer styrene solution accounts for 55～65 weight %; Aluminium hydroxide is the hydrated aluminum oxide powder; Thinner is a monomer styrene solution; Initiator is a peroxidized t-butyl perbenzoate; Releasing agent is the zinc stearate powder; The viscosity reduction treating compound is the BYK-966 type auxiliary agent that German Bi Ke chemical company produces; Rheological agent is the BYK-LPR20262 type auxiliary agent that German Bi Ke chemical company produces; Thickening material is a magnesium oxide solution.
Take such scheme, have the following advantages:
Because adopting the metaphenylene unsaturated polyester resin of stable performance in the high electric strength flame-proof continuous insulation dip molding material of the present invention is main raw material, with aluminium hydroxide with flame retardant properties as filler, be equipped with the viscosity reduction treating compound again and soak into dispersion, and be used for preventing filler and pigment precipitation, the rheological agent that is separated and grows dim is used, can adjust the thixotropic property of each stock yard automatically, make each raw material mix the mobile uniformity in back, each unanimity that is evenly distributed mutually, make that the anti-electrical strength of moulding compound make is higher, but proof voltage 15kv/mm after testing, more than the 240s of anti-electric arc.Because the anti-electrical strength of the present invention is higher, not only can be used on proof voltage and the less demanding low voltage equipment of anti-arc stiffness, can also be used on the high-voltage electrical equipments such as apparatus insulator that proof voltage and anti-electric arc are had relatively high expectations, insulating boot, the scope of application is wider.
