Abstract
The invention discloses a light fireproof insulation type composite panel suitable for a plant building, relating to a building material and solving the problem that an existing building panel can not simultaneously meet requirements of light weight, load bearing, fire prevention, and good insulation property. The light fireproof insulation type composite panel comprises raw materials of 20-90 parts of gypsum powder, 1-8 parts of gypsum fibers, 2-9 parts of pulverized fuel ash, 0.2-0.6 part of foaming agent, and 0.1-1.5 parts of sodium dodecyl sulfate. The light fireproof insulation type composite panel is prepared by adopting the following steps: grinding and crushing the pulverized fuel ash, mixing with the gypsum powder and the gypsum fibers and dissolving in water, controlling the temperature to be 20-40 DEG C, adding the foaming agent and stirring for 5-8 min, raising the temperature to 100-110 DEG C, adding the sodium dodecyl sulfate, continuously stirring for 5-8 min to obtain a sandwich material; and then laying between two precoats, and pressurizing and foaming to obtain the light fireproof insulation type composite panel. The light fireproof insulation type composite panel disclosed by the invention is suitable for a building shed and a factory, light in weight, high in strength, better in thermal insulation and fire prevention properties, and capable of thoroughly avoiding risks such as open fire combustion.
Description
Technical field
The present invention relates to material of construction, be specifically related to a kind of lightweight fireproof insulating type composition board that is applicable to factory building.
Background technology
At present, on market, common structural lumber has foam composite board, cement plate, Bars In Poured Concrete Slab, styrofoam etc.Along with the popularization of Highrise buildings, large-sized workshop, framed building, building trade is also more and more higher to the requirement of sheet material.
Existing cement plate, concrete slab or Bars In Poured Concrete Slab, have the advantages that fire resistance property is strong, but exist panel weight large, the defect that waterproof and effect of heat insulation are poor; Foam composite board has advantages of that weight is little, but heat insulation effect is poor, especially exists and meets high temperature or subtract the inflammable fatal shortcoming of naked light; There is the advantage of high insulating effect in styrofoam, but a little less than load-bearing and fire resistance property.
Patent of invention " a kind of light fire-proof heat insulating composite plate and production method thereof (CN102155070B) ", the technical scheme of central layer taking quick hardening sulphoaluminate cement and flyash as major ingredient disclosed, but, because major ingredient is still cement, so still have the large defect of the weight of sheet material own, and the heat insulation effect of cement is poor.
Patent of invention " a kind of preparation method (CN102249634B) of building composite board ", disclose a kind of taking 18.5 parts of lime powders, 26 parts of nut-shells, 20 parts of sheet materials that terra alba is made as main raw, be mainly used in non-bearing inside and outside wall board, a little less than there is weight capacity, heat insulation effect is not good shortcoming.
In sum, cannot meet in order to solve existing building sheet material that quality is light, weight capacity is strong, the requirement of fireproof heat insulating simultaneously, and research and develop a kind of novel building board.
Summary of the invention
The present invention be cannot meet in order to solve existing building sheet material that quality is light simultaneously, the problem of load-bearing, fire prevention, requirement that insulated capacity is good, and a kind of lightweight fireproof insulating type composition board is provided.
The present invention is achieved by the following technical solutions:
A kind of lightweight fireproof insulating type composition board, raw material comprises the terra alba of 20-90 part, the gypsum fiber of 1-8 part, the flyash of 2-9 part, the whipping agent of 0.2-0.6 part, the sodium laurylsulfonate of 0.1-1.5 part, prepared by following method: flyash is ground, with terra alba, gypsum fiber mixes and is water-soluble, control temperature at 20-40 DEG C, add whipping agent to stir 5-8min, then be warming up to 100-110 DEG C, add sodium laurylsulfonate, continue to stir 5-8min, obtain sandwich material, then in the middle of two-layer precoat, mat formation, extrusion forming, obtain.
Further, above-mentioned lightweight fireproof insulating type composition board, preferred feedstock comprises 85 parts of terra albas, 5.5 parts of gypsum fibers, 7 parts of flyash, 0.3 part of whipping agent, 0.8 part of sodium laurylsulfonate.
Described terra alba is high strength gypsum powder, because gypsum itself has the feature of insulation, fire prevention, light weight, insulation, easily processing, respiratory function, good decorative property, in the time using high strength gypsum powder for raw material, because porosity after the sclerosis of high strength gypsum powder is little, after the effect of emulsifying agent sodium laurylsulfonate, the sheet material making is keeping, on the basis of common gypsum powder advantage, also further having strengthened the intensity of board wall.
Described flyash is the low-grade flyash grinding, and granularity is 0.3-3mm, and specific surface area is 350-500m
2/ Kg, the mass percent of chemical composition is, SiO
238-45%, CaO48-50%.
Described whipping agent is foam concrete foamer.
The present invention has used the gypsum fiber of 1-8 part as a kind of auxiliary packing, because gypsum fiber integrates the two advantage of fortifying fibre and ultra-fine inorganic filler, in the time making sheet material, adding in the gypsum fiber situation of above-mentioned weight part, not only can play the effect of strengthening and toughening, also can play the effect of insulation, fire-retardant, refractory heat-insulating simultaneously.
In order to verify the performance of product of the present invention, volume density, ultimate compression strength, combustibility, thermal conductivity, heat transfer coefficient, the fire resistance of product are measured respectively, wherein terra alba used is high strength gypsum powder, within 2 hours, folding strength is 5.0-6.0MPa, and within 2 hours, ultimate compression strength is 15-18MPa, adds the anti-folding of auxiliary material sheet material, ultimate compression strength declines to some extent, the actual ultimate compression strength that detects can reach 7.5-10.5MPa, and fire resistance reaches does not fire A level, and wherein the thick thermal conductivity of 10cm is 0.05-0.1W/m
2.K.
Compared with prior art, preparation method of the present invention is simple, easy handling, and product application scope is wide, is particularly useful for building builder's temporary shed, factory building, and quality is light, intensity is high, and has good insulated fire, can thoroughly evade naked light burning equivalent risk.
