Abstract
The invention relates to a manufacturing process of a metal surface heat-insulation board based on an ultralight foaming cement core, solving the non-fireproof problem of an organic plastic sandwich board in the traditional metal surface sandwich heat-insulation board and the technical problem of reduced heat-insulation property due to settlement shrinkage and decreased volumes of moisturized metal surface rock-wool and metal surface mineral wool sandwich plates. The technical scheme is as follows: the process comprises two major process steps of: forming a metal shell and preparing a heat-insulation inner core by utilizing ultralight foaming cement mortar. The process is characterized in that a sealed-type metal shell is utilized as a forming die; the foaming cement mortar is poured into the forming die and a foaming expansion space is reserved; after being solidified, the foaming cement mortar is filled into an inner cavity of the metal shell to form the heat-insulation inner core of the heat-insulation board. The continuous and mechanical production is designed, the problems of poor heat-insulation effect and low strength of the metal surface sandwich heat-insulation board are solved, meanwhile, a fireproof material is utilized as the heat-insulation inner core which reaches the national fireproof grade requirement, and therefore, the integrated intensity of the board is improved.
Description
Technical field
The present invention relates to a kind of manufacture craft of light Steel-Structure Factory with Steel metal covering heat preservation plate material, belong to building field, particularly a kind of ultralightization and there is the manufacture craft of the light Steel-Structure Factory with Steel metal covering insulation sandwich board based on ultra-light foaming cement material of fabulous heat-insulating property.
Background technology
Metal skinned sandwich panel is due to its excellent performance, and efficiently application property and good heat insulation property are accepted extensively by people gradually easily, and is widely used in the various factory building of building, workshop, lightly constructed and simply equipped building, board house, warehouse.But metal decking sandwiched plate in the market has metal covering organic plastics insulation sandwich board, as polystyrene, hard-foam polyurethane etc., good heat insulating but do not reach National Fire requirement; Though metal covering rock wool, mineral wool sandwiched plate etc. reach fire protection requirement, its rock wool, mineral wool sandwiched plate is domestic produces mainly with two dimensional method, its wet humid air and the easy sedimentation of water volume are shunk and metal decking departs from, heat-insulating property reduces, and cost is higher, though performance increases when producing with 3D approach, cost is just higher.Above two kinds of plates are when metal covering is corrugated, a tympanic part position hollowing of metal covering, moisture laden air will be entered, reduce insulating power, cause the corrosion of metal plate, simultaneously also unfavorable to the bulk strength of plate, simultaneously because the Material Strength of its heat preservation core layer adopted is low, cause the bulk strength of sheet material also not high.In prior art, metal covering heat insulating sandwich sheet material adopts typical sandwich structure due to it, the edge of heat preservation core layer is due to exposed with air for a long time, because the heat-insulating property of metal covering heat preservation plate material can fall in oxidized or infiltration gradually, simultaneously because its bridging arrangement is unreasonable, cause sheet material finally can not accomplish waterproof, fire prevention, be applied in building and will there is great potential safety hazard.
Summary of the invention
The present invention reduces the technical problem of heat-insulating property in order to sedimentation retraction volume after solving the not fire-resistant problem of organic plastics sandwiched plate, metal covering rock wool, metal covering mineral wool sandwiched plate in the sandwiched heat insulation board of metal current face and making moist reduces, devise a kind of manufacture craft of the metal covering heat preservation plate material based on ultra-light foamed cement tire core, can serialization, mechanization production, solve the problem that metal covering heat insulating sandwich sheet material heat insulation effect is poor, intensity is low, have employed fire prevention material as heat insulation inner core simultaneously, reach the fire-protection rating of national requirements, improve the bulk strength of sheet material.
The present invention is the technical scheme realizing goal of the invention employing, a kind of manufacture craft of the metal covering heat preservation plate material based on ultra-light foamed cement tire core, it is shaping and prepare heat insulation inner core two large divisions processing step with ultra-light foamed cement mortar that above technique comprises metal shell, key is: this technique adopts closed metal shell to be moulding form, in moulding form, pours into foam cement slurry and reserved foaming slurry expansion space, riddle the heat insulation inner core that metal shell inner chamber forms heat preservation plate material after the solidification of foam cement slurry, concrete steps comprise:
A, allotment foam cement mortar, for subsequent use;
B, make closed moulding form: according to the geometric shape designing requirement of metal covering heat preservation plate material, make the closed metal shell of heat preservation plate material, the technique opening that closed metal shell is arranged comprises grout hole, steam vent;
C, grouting: in closed moulding form, inject deployed foam cement slurry by grout hole and reserved foaming space, riddle dies cavity after the solidification of foam cement slurry, form the heat insulation inner core of heat preservation plate material;
D, after heat insulation inner core is shaped, trim process opening part expansion overflow, plugging technology mouth, form metal covering heat preservation plate material.
Key of the present invention is: adopt the rolling of metal sheet mould pressing process one, be processed to form closed metal shell, add bearing strength and the durability of metal covering heat preservation plate material; By technique opening to shell perfusion in vivo foam cement slurry, and reserved foaming space, foam cement slurry foaming and intumescing in housing riddles housing cavity, in foaming process, because housing is closed shell, after the foaming of foam cement slurry riddles housing cavity, continue foaming and produce interior pressure, foam cement slurry flows into the corner of housing cavity under pressure, evicts out of the air of corner, strengthen the heat-insulating property of metal covering heat preservation plate material, avoiding sheet material to play drum affects heat-insulating property; Instead of organic plastics warming plate as heat preservation core layer using this incombustible material of ultra-light foaming cement material simultaneously, strengthen the fireproof performance of sheet material.
The invention has the beneficial effects as follows: while reaching substantially suitable coefficient of thermal conductivity, solve the nonfireproof shortcoming of metal covering organic plastics insulation sandwich board; Overcome metal surface rock wool sandwich panel, metal covering mineral wool sandwiched plate make moist after sedimentation contraction, volume reduce, coefficient of thermal conductivity improve shortcoming; Overcome metal covering organic plastics insulation sandwich board, metal surface rock wool sandwich panel, metal covering mineral wool sandwiched plate when metal decking is corrugated, bossing hollowing and cause moisture laden air enter reduce insulating power, cause the corrosion of metal plate and cause slab integral intensity reduce problem; The insulation sandwich board cost adopting this technique to make is low, intensity is high, overall performance good; Except metal covering organic plastics insulation sandwich board, lower than other metal covering insulation sandwich board costs.
