Abstract
The present invention discloses a kind of A2 level fireproof core board and manufacture method thereof, it is by preventing fires core layer and polymeric membrane adhesives forms, described fireproof core board is sheet structure, described sheet being rolled into volume shape, the method comprises the steps: batching, discharging, toasts, rolls, cools and make volume shape. Central layer internal density being increased, thus improves anti-fire intensity, combustionproperty meets the specified requirement of A2 level; Sheet is rolled into shape and packs, and other clients can be processed into fire-resistant composite panel again according to self production requirement, can with the metal sheet compound such as aluminium sheet, copper coin or stainless steel plate, reduce production cost, save resource, be convenient to mass production and use.
Description
Technical field
The present invention relates to the manufacture method of a kind of fireproof core board and central layer thereof, be related specifically to a kind of can by central layer rolling make A2 level fireproof core board and manufacture method.
Background technology
At present, what plastic core material adopted is that inflammable material polyethylene does base material, when its shortcoming carries out fire prevention detection in vertical combustion stove, at high temperature core and aluminium sheet are easy to delamination, cause polyethylene at high temperature with direct flame contact, polyethylene easy firing drippage simultaneously, thus big fire of igniting, add that architectural decoration material easily fires, fire is caused to occur repeatedly, at present, the fireproof aluminum-plastic board related to, though a kind of energy-saving environmentfriendly products, owing to adopting after directly slip being injected pressing mold traditional method to heat pressuring method, its insufficient strength, fire performance is not high, still there is potential safety hazard, can not meet the need of market, in addition, no matter plastic core material or the fireproof aluminum-plastic board being made up of traditional way, its core material structure is not except itself reaching A2 level fire resistance, itself structure can not make specific shape, finished product is made with aluminium sheet or other metal sheets and integrally transports, increase cost, reduce the use range of fireproof core board, it is not easy to promote the use.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of intensity height, fire resistance are good, the manufacture method of convenient transportation and A2 level fireproof core board applied widely and this fireproof core board.
In order to solve the problems of the technologies described above, the present invention provides a kind of A2 level fireproof core board, and it is by preventing fires core layer and polymeric membrane adhesives forms, described fireproof core board is sheet structure, described sheet can be rolled into volume shape, and the raw material that described fire prevention core layer comprises following weight part number mixes: calcium carbonate 86, silica flour 128, quartz sand 87, perlite 25, polypropylene short fiber 9, silicon-dioxide 50, aluminium hydroxide 60, zinc molybdate 20, acrylic latex 140 forms.
Present invention also offers the manufacture method of a kind of A2 level fireproof core board, the method comprises the steps.
Step 1: measure in percentage terms, by calcium carbonate 86, silica flour 128, quartz sand 87, perlite 25, polypropylene short fiber 9, silicon-dioxide 50, aluminium hydroxide 60, zinc molybdate 20, mixing machine mixing put into by acrylic latex 140, stirs into slip.
Step 2: slip is sent into transfer roller chamber indoor, extruded by slip, then be fitted in slurry two ends by upper and lower for the non-woven fabrics of rolling two layers, is extruded by roller wheel and forms non-solid shape fire prevention core structure.
Step 3: by not shaping fireproof core board bulk transport at least three road hot air circulation oven for baking, the temperature of baking is 80 DEG C-240 DEG C, toasts 10-15 minute; In bake process, along with the slowly solidification of slurry, form the solid state fire prevention core structure at initial stage, then by the roll extrusion of continuous several times and baking, core is shaped substantially; Carry out 140 DEG C-240 DEG C bakings again, after baking, it is delivered to single roller bundle machine and finally rolls; And then send into temperature adjustment baking box, core is heated to 110-150 DEG C, being provided with on coating machine and put film machine, put and be placed with polymeric membrane adhesives on film machine, be combined into one fire prevention core layer and polymeric membrane adhesives formation fireproof core board after two roller coating machine roll extrusion.
Step 4: be delivered in cooling tank to carry out cooling process by the fireproof core board after extruding, carries out fixed width cutting to core edges after cooling.
Step 5: the volume that is delivered on winder by a continuous fireproof core board harvest, fireproof core board is made volume shape and is packed the most at last. A2 level fireproof metal composition board just can be produced by recombining process metal sheet in this core two compounds again with this A2 level fire prevention core volume.
Adopt as above after technical scheme, according to above-mentioned raw materials proportioning, carry out after having prepared burden toasting, roll, with cooling program, core is roasted into solid sheet by liquid batching, central layer internal density is increased, thus improve anti-fire intensity, and use the operation of said procedure, 3. density be more than or equal to 1600kg/m, thickness is more than or equal to the product of 2mm, and combustionproperty meets the specified requirement of A2 level; Sheet is rolled into shape and packs, and other clients can be processed into fire-resistant composite panel again according to self production requirement, can with the metal sheet compound such as aluminium sheet, copper coin or stainless steel plate, reduce production cost, save resource, be convenient to mass production and use.
