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 carbon dioxide-shielded welding insulation covering, particularly the preparation method that overlaps of a kind of high temperature insulation.
Background technology
Carbon dioxide-shielded welding due to its cost low, carbon dioxide is easily produced, and is widely used in Ge great small business.Shield carbon-dioxide arc welding (is called for short CO
2weldering) shielding gas be that carbonic acid gas (adopts CO sometimes
2the mixed gas of+Ar).Due to the Special Influence of the heat physical properties of carbon dioxide, when using normal welding power supply, end of welding head deposite metal can not form the free transition of axis of balance, usually need to adopt short circuit and molten drop necking down quick-fried disconnected, therefore, weld free transition phase ratio with MIG, splash more.But as adopted high-quality welding machine, Selecting parameter is suitable, can obtain very stable welding process, makes splashing be reduced to minimum degree.Because shielding gas used is cheap, when adopting short circuiting transfer, formation of weld is good, adds and uses the welding wire containing reductor can obtain good quality solder joints without subsurface defect.Therefore this welding process has become one of most important welding process of ferrous material at present.
Carbon dioxide-shielded welding insulation covering is in high temperature the effect of bearing several Baidu high temperature and continuing for a long time, and the highest temperature environment of bearing 300-500 DEG C of original insulation covering material, in use needs replacing 2 to 3 to overlap, affect production efficiency and cost every day.
Summary of the invention
Technical problem to be solved by this invention is to provide the preparation method of a kind of high temperature insulation cover, the method technique is simple, cost is low, high temperature resistant component is introduced in resin, product life improves, disposal molding 4 products in 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, the refractory ceramics component of 50 ~ 60% is dried respectively, after mixing again with 40 ~ 50% mixed with resin, in forming mould together with steel structure part 180 ~ 185 DEG C solidification 6 ~ 8 seconds, solidifying pressure is 30-80MPa, the then demoulding, to obtain final product.
Described refractory ceramics component is one or more in magnesium oxide, mica powder, talcum powder, Suzhou soil, silicon oxide, aluminum oxide, acicular wollastonite.
By weight percentage, when the component of described resin is 40%, refractory ceramics component is: magnesium oxide 4%, mica powder 12%, talcum powder 25%, Suzhou soil 8%, silicon oxide 8%, Zinic stearas 3%.
By weight percentage, when the component of described resin is 38%, refractory ceramics component is: magnesium oxide 5%, mica powder 12%, talcum powder 6%, silicon oxide 15%, aluminum oxide 20%, Zinic stearas 4%.
By weight percentage, when the component of described resin is 50%, refractory ceramics component is: mica powder 15%, silicon oxide 10%, aluminum oxide 3%, acicular wollastonite 19%, Zinic stearas 3%.
The present invention adopts in resin the refractory ceramics component introducing high temperature insulation, as components such as magnesium oxide, mica powder, talcum powder, Suzhou soil, silicon oxide, aluminum oxide, acicular wollastonites, each component is fully dried, proportioning, mixing, after weighing, in forming mould, heat-pressure curing is shaping, namely obtains insulation covering finished product after the demoulding.
