Description
Technical field
The invention belongs to the ceramic fiber material technical field, be specifically related to a kind of ceramic fiber building fireproof plate and preparation method thereof.
Background technology
Traditional ceramic fiber building fireproof plate is general adopts two kinds of operational paths to be produced, a kind of is to adopt wet method vacuum forming or wet method fourdrinier forming technique, the ceramic fiber slip is made to the wet base of water ratio 150-250% (butt), then the base that will wet is dry and make product.The ceramic fiber building fireproof plate of making like this will consume more energy consumption in drying course, in the slip moulding process, have the large particularly organic silicone oil emulsion water-resisting agent of the material loss large drawback that runs off, this traditional wet production pattern has caused unintentionally the waste of the energy and material simultaneously.Another kind is to adopt dry method resin heat curing process, but the ceramic fiber dry method plate that this traditional technology is produced is not containing expanded vermiculite powder and clay, thereby its intensity and hardness do not reach the level of wet moulding ceramic beaverboard, in fields such as steel structure fireproofing, fire partitions, can not meet service requirements.Therefore, be necessary to develop a kind of dry formed hydrophobic ceramic fiber building fireproof plate product and production technology thereof, both had that dry process for forming is energy-conservation, a material-saving, quick-drying advantage, have advantages of that again the wet therapy forming process product strength is high, hardness good.
Summary of the invention
According to the prior art deficiency, technical problem to be solved by this invention is: a kind of dry formed hydrophobic ceramic fiber building fireproof plate and preparation method thereof is provided, can effectively improve resistance toheat, fire resistance, heat-proof quality and the intensity of building fireproof plate, volume density and production cost are reduced widely.
The technical solution adopted for the present invention to solve the technical problems is: a kind of dry formed hydrophobic ceramic fiber building fireproof plate is provided, it is characterized in that being comprised of the raw material of following parts by weight:
50～95 parts of aluminum silicate fibers
0～20 part of expanded vermiculite powder
0～20 part of clay
2～8 parts of toners
0.2～0.6 part of mineral grease
0.1～0.5 part of organic silicone oil emulsion.
Described ceramic fiber building fireproof plate is comprised of the raw material of following parts by weight:
80～85 parts of aluminum silicate fibers
5～7 parts of expanded vermiculite powders
5～7 parts of clays
3～4 parts of toners
0.3～0.4 part of mineral grease
0.2～0.3 part of organic silicone oil emulsion.
Described clay is wilkinite, kaolin, soft clay, semisoft clay, ball clay or attapulgite.
Described toner is one or both in resol or melamine formaldehyde resin.
Described mineral grease is kerosene or diesel oil.
Described organic silicone oil emulsion is cationic hydroxy silicone oil emulsion or containing hydrogen silicone oil emulsion.
Described making method is, after raw material is mixed, to be deployed into glue, then, after emulsion dispersion, with aluminum silicate fiber, mixes, and after the twin rollers pressed sizing, heat setting type and drying in curing oven.
By mixed raw material in resistance furnace through 2000 ℃ of-2200 ℃ of high-temperature fusion, to flow thigh with centrifugal tumbling machine and get rid of silk, the centrifugal force produced by high speed rotating becomes ceramic fiber by the molten mass drawing-down, again by ceramic fiber by condensers collection cotton, form more open cotton base, by twin rollers compression moulding, finally cotton base is sent into to the curing oven dryness finalization again.According to product volume density difference, the pressure of twin rollers can be regulated in the 0.05-0.5MPa scope, the variation from 10mm to 80mm according to products thickness simultaneously, and the temperature of curing oven dryness finalization is regulated between 150-250 ℃, and be 0.2-5 hour time of drying.
The gelatin concentration raw materials quality of allotment should be 20.0%～50.0% of total mass.
Product after dryness finalization is cut into standardized goods by the ceramic fiber building fireproof plate of continuous length, and plastic sealing pack, automatic stacking.
Aluminum silicate fiber is the common silicic acid aluminum shot shape cotton produced by Shandong Luyang share co.,ltd, product designation LYGX-111.This fiber is to take the flint clay grog as main raw material(s), adopts the resistance furnace melting to prepare through centrifugal drying silk fiber-forming process.
Expanded vermiculite powder and clay are strongtheners, and expanded vermiculite powder and clay have not only improved the intensity of ceramic beaverboard but also reduced cost as the filler compound use.
Beneficial effect of the present invention is:
(1) ceramic beaverboard that the present invention develops adopts ceramic fiber as base material, the expanded vermiculite powder (light filler) and the clay filler that add suitable proportion, can effectively improve resistance toheat, fire resistance, heat-proof quality and the intensity of building fireproof plate, volume density and production cost are reduced widely, and can be used as the upgraded product to traditional architecture fire-proof boards such as chlorine oxygen magnesium inorganic fire-proof plate, calcium silicate boards.Product of the present invention; according to " building slab fire testing method " (GB/T9978-1999) standard detection; reach the fire resistance rating one-level that " Code for fire protection design of high rise buildings " defines beam in (GB50045-2001); fire performance is 2.0h at least; according to " building slab fire prevention spray material method for testing performance " GA110-1995 standard detection; reach the fire resistance rating one-level that " Code for fire protection design of high rise buildings " defines post in (GB50045-2001); fire performance is no less than 3.0h, and the thickness of light fire-proof protecting sheet is not more than 30mm.
(2) from aspects such as product cost performances, consider, the ceramic fiber building fireproof plate that the present invention develops, compare with traditional traditional inorganic fibre thermal baffle for buildings such as mineral wool decorative acoustic board, has comparatively significantly price advantage.Although product ton cost of the present invention slightly is improved, the volume cost of product reduces.As traditional mineral wool decorative acoustic board price is 750 yuan/m
3, and the ceramic fiber building fireproof plate price is only 660 yuan/m
3, the unit volume price obviously reduces, and the thermal baffle for buildings fire-protection rating than traditional is high simultaneously, and good heat-insulation effect is lightweight, and intensity and good springiness, so be the upgraded product of inorganic fibre thermal baffle for buildings.Ceramic fiber building fireproof plate of the present invention, its unit weight is between 150-350kg/m3, when unit weight at 200kg/m
3When above, main physicochemical property has reached the respective standard of national steel structure fire-proof paint GB14907-2002 medium-thick type steel structure fire-proof paint, and its volume density of indoor thick-layered fire coating is not more than 500kg/m
3, compressive strength reaches 0.3Mpa, and fire endurance is not less than 2h (coat-thickness is 25 ± 2mm).
(3) the present invention adopts dry process for forming production, and the not enough 800kg of the water consumption of ceramic beaverboard per ton, do not exist water cycle and sewage discharge problem, and not containing organic toxicity volatile matters such as formaldehyde, environmental protection.With traditional wet process technique, compare, more than the few water 1000kg of ceramic fiber PLASTIC LAMINATED per ton, the consumption of the hydrophober such as mineral grease and organic silicone oil emulsion also can reduce 30%-50% simultaneously.So not only reduce drying cost, also saved the consumption of the precious materials such as hydrophober.
