Abstract
The present invention relates to a kind of resin and preparation method thereof being applied to high temperature insulation cover, the component of resin is: by weight percentage, the resin of 40 ~ 50% and the refractory ceramics component of 50 ~ 60%.Preparation method comprises: by the resin of 40 ~ 50% and 50 ~ 60% refractory ceramics component dry after mix, in forming mould 180 ~ 185 DEG C solidification 6 ~ 8 seconds, solidifying pressure is 30-80MPa, the then demoulding, to obtain final product.The present invention introduces high temperature insulation refractory ceramics component of good performance in the resin of insulation covering material, thus the heatproof temperature of insulation covering is brought up to 800-1000 DEG C, thus greatly improve the work-ing life in applied at elevated temperature process, 3-4 days can be used continuously through using often cover, improve production efficiency, reduce production cost; Preparation technology is simple, and cost is low, has a good application prospect.
Description
Technical field
The invention belongs to resin and preparation field thereof, particularly a kind of resin and preparation method thereof being applied to high temperature insulation cover.
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 a kind of resin and preparation method thereof being applied to high temperature insulation cover, introduces high temperature insulation refractory ceramics component of good performance, thus the heatproof temperature of insulation covering is brought up to 800-1000 DEG C in this resin; Preparation technology is simple, and cost is low, has a good application prospect.
A kind of resin being applied to high temperature insulation cover of the present invention, the component of described resin is: by weight percentage, the resin of 40 ~ 50% and the refractory ceramics component of 50 ~ 60%.
Described refractory ceramics component is one or more in magnesium oxide, mica powder, talcum powder, Suzhou soil, silicon oxide, aluminum oxide, acicular wollastonite.
The component of described resin is: by weight percentage, resin 40%, magnesium oxide 4%, mica powder 12%, talcum powder 25%, Suzhou soil 8%, silicon oxide 8%, Zinic stearas 3%.
The component of described resin is: by weight percentage, resin 38%, magnesium oxide 5%, mica powder 12%, talcum powder 6%, silicon oxide 15%, aluminum oxide 20%, Zinic stearas 4%.
The component of described resin is: by weight percentage, resin 50%, mica powder 15%, silicon oxide 10%, aluminum oxide 3%, acicular wollastonite 19%, Zinic stearas 3%.
The method of the resin that a kind of Application and preparation of the present invention overlaps in high temperature insulation, comprising:
By weight percentage, by the resin of 40 ~ 50% and 50 ~ 60% refractory ceramics component dry after mix, in forming mould 180 ~ 185 DEG C solidification 6 ~ 8 seconds, solidifying pressure is 30-80MPa, the then demoulding, to obtain final product.
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.
beneficial effect
The present invention introduces high temperature insulation refractory ceramics component of good performance in the resin of insulation covering material, thus the heatproof temperature of insulation covering is brought up to 800-1000 DEG C, thus greatly improve the work-ing life in applied at elevated temperature process, 3-4 days can be used continuously through using often cover, improve production efficiency, reduce production cost; Preparation technology is simple, and cost is low, has a good application prospect.
