Abstract
The invention relates to a process for preparing a heat-resistant insulating sleeve. The process comprises the steps of by weight, drying heat-resistant ceramic constituents of 50-60% respectively, mixing uniformly, then mixing with resin of 40-50%, curing with a copper structure member for 6-8 seconds at 180-185DEG C in a forming mold with the curing pressure of 30-80MPa, then demoulding, and obtaining the heat-resistant insulating sleeve. The process is simple in preparation technology and low in cost, heat-resistant constituents are introduced into the resin, the product life is prolonged, four products are formed once in a forming process, the rate of finished products is high, the production efficiency is high, and the process has good application prospects.
Description
Technical field
The invention belongs to the preparation field of CO, particularly a kind of preparation method of high temperature insulation cover with insulation covering.
Background technology
CO is because its cost is low, and dioxide gas is prone to produce, and is widely used in each big peanut.Shield carbon-dioxide arc welding (is called for short CO
2Weldering) shielding gas is that carbonic acid gas (adopts CO sometimes
2The mixed gas of+Ar).Because the special influence of the heat physical properties of dioxide gas; When using conventional welding source, end of welding first melt metal can not form the axial free transition of equilibrated, needs to adopt short circuit and molten drop necking down quick-friedly to break, therefore usually; Weld free transition phase ratio with MIG, it is more to splash.But as adopting the high-quality welding machine, it is suitable that parameter is selected, and can obtain very stable welding process, and making splashes is reduced to minimum degree.Because used shielding gas is cheap, formation of weld is good when adopting short circuiting transfer, adds the good quality solder joints of using the welding wire that contains reductor can obtain not have subsurface defect.Therefore this welding process has become one of most important welding process of ferrous material at present.
CO is in for a long time with insulation covering and bears the effect that several Baidu high temperature continues in the high temperature, and the highest temperature environment of bearing 300-500 ℃ of original insulation covering material in use need be changed 2 to 3 covers every day, influences production efficiency and cost.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of high temperature insulation cover, and this method technology is simple, and cost is low; In resin, introduced high temperature resistant component; Product life improves, 4 products of disposal molding in the moulding process, and yield rate is high; Production efficiency is high, has a good application prospect.
The preparation method of a kind of high temperature insulation cover of the present invention; Comprise: by weight percentage, 50 ~ 60% refractory ceramics component is dried respectively, after mixing again with 40 ~ 50% mixed with resin; In forming mould with steel structure spare together 180 ~ 185 ℃ solidified for 6 ~ 8 seconds; Solidifying pressure is 30-80MPa, and the demoulding then promptly gets.
Said refractory ceramics component is one or more in Natural manganese dioxide, mica powder, talcum powder, Suzhou soil, silicon oxide, aluminum oxide, the acicular wollastonite.
By weight percentage, the component of said resin is 40% o'clock, and the refractory ceramics component is: Natural manganese dioxide 4%, mica powder 12%, talcum powder 25%, Suzhou soil 8%, silicon oxide 8%, Zinic stearas 3%.
By weight percentage, the component of said resin is 38% o'clock, and the refractory ceramics component is: Natural manganese dioxide 5%, mica powder 12%, talcum powder 6%, silicon oxide 15%, aluminum oxide 20%, Zinic stearas 4%.
By weight percentage, the component of said resin is 50% o'clock, and the refractory ceramics component is: mica powder 15%, silicon oxide 10%, aluminum oxide 3%, acicular wollastonite 19%, Zinic stearas 3%.
The present invention adopts the refractory ceramics component of introducing high temperature insulation in the resin; Like components such as Natural manganese dioxide, mica powder, talcum powder, Suzhou soil, silicon oxide, aluminum oxide, acicular wollastonites; The fully oven dry of each component, proportioning, mixing; Weigh the back in forming mould the heating and pressurizing curing molding, promptly get the insulation covering finished product after the demoulding.
