Abstract
The invention relates to a preparation method of a fiber cement coal ash foam battenboard, comprising the following steps: (1) first evenly mixing 75-85% of coal ash, 8-13% of cement, 3.5-6.5% of fiber and 1.8-2.1% of binding agent by weight percent, placing the mixture into a reaction utensil and then adding 2.5-3.5% of foaming agent; (2) tanking up a foam (2) formed in step (1) between two cement boards (1); then placing the foam (2) in a high pressure steam oxygen container with a pressure of 0.1-1MPa and evaporating the foam (2) to dryness within 1-6h in the high pressure steam oxygen container; and (3) extracting the dried foam from the high pressure steam oxygen container and cooling and solidifying the dried foam. With the preparation method, the fiber cement coal ash foam battenboard has the advantages of good fire prevention property, water prevention property, corrosion prevention property, sound insulation property and thermal insulation property, long service life and low cost.
Description
One, technical field
The present invention relates to a kind of preparation method of fiber cement coal ash foam battenboard, specifically a kind of making has that fire prevention, waterproof, anticorrosion, unit weight are little, the preparation method of the composite board of good heat insulation, intensity height and elasticity and good toughness.
Two, background technology
Along with rapid economy development, also all in construction, various building heat preservation Light wallboard material use amounts are big for a large amount of buildings, the building materials that adopt industrial waste to make, not only energy-conservation but also environmental protection.And existing steel plastic foam battenboard is widely applied under construction, and the steel plate of both sides is perishable, and service life is short, though middle plastic foam good heat insulating, unit weight is little, and fire prevention, water resistance are poor, easily catch fire, cause hidden danger in building with in using; And lose insulation effect or come off after the water inlet.The light-weight brick that the fly ash composite material that has is made and sheet material unit weight is big, thermal conductivity factor is high, intensity is low and elasticity and toughness are bad just is to use other lightweight body of wall and cost height, and as the compound light wall board of cement plastics foam cost height not only, and unit weight is big.
Three, summary of the invention
In order to overcome above-mentioned technological deficiency, the invention provides a kind of preparation method of fiber cement coal ash foam battenboard; Fire prevention, waterproof, anticorrosion, sound insulation, good heat insulating, the life-span is long, cost is low.
The technical solution used in the present invention is: a kind of preparation method of fiber cement coal ash foam battenboard, and its preparation method is:
(1), flyash 75-85%, cement 8-13%, fiber 3.5-6.5% and adhesive 1.8-2.1% evenly mixed put in the reaction vessels, add blowing agent 2.5-3.5% again;
(2), in the middle of two cement plates, fill the foams that form through step 1; Being put into pressure then is in the high pressure steaming oxygen container of 0.1-1MPa, through steamed the evaporate to dryness of oxygen container in 1-6 hour at high pressure;
(3), steam the oxygen container and take out from high pressure after, cooled and solidified.
The foams of being made up of flyash, cement, fiber, adhesive and blowing agent steam to solidify to have formed in the oxygen container at high pressure and are the honeycomb state, have formed fiber cement coal ash foam battenboard with cement plate; Owing to used flyash and cement to be main material, consumed the waste material flyash that the thermal power plant produces simultaneously, so fire prevention, waterproof and imputrescibility can be good, cost is low.
The present invention has designed, and adhesive is set to inorganic bond or organic bond.The scope of application is wide.
The present invention has designed, and blowing agent is set to metal foaming agent or nonmetal blowing agent.The scope of application is wide.
Four, description of drawings
Accompanying drawing is a schematic diagram of the present invention.
Five, the specific embodiment
The present invention is using flyash to be primary raw material, and blowing agent is an auxiliary material.
Embodiment 1: a kind of preparation method of fiber cement coal ash foam battenboard, and its preparation method is:
(1), flyash 75%, cement 13%, fiber 6.5% and adhesive 2.1% evenly mixed put in the reaction vessels, add blowing agent 3.4% again;
(2), cement plate 1 is fixed on the both sides of mould, in the middle of two cement plates 1, fill foams 2; Again the mould of filling foams 2 is put into high pressure and steams in the oxygen container, steam 1 hour evaporate to dryness in the oxygen container for the 1MPa high pressure at saturation vapour pressure;
(3), treat mold cools down after, remove mould after, just formed fiber cement coal ash foam battenboard.
In the present embodiment, the cooling settings in the step 3 is the nature cooling.
In the present embodiment, be of a size of 600mm * 900mm * 100mm.
In the present embodiment, cement plate 1 is set to fiber cement board, and fiber is set to string; Adhesive is set to inorganic bond waterglass, and blowing agent is set to metal foaming agent aluminium powder.
The foams of being made up of flyash, cement, fiber, adhesive and blowing agent 2 steam to solidify to have formed in the oxygen container at high pressure and are the honeycomb state, have formed fiber cement coal ash foam battenboard with cement plate 1.Owing to used cement and adhesive, make foams 2 more firm with connecting of cement plate 1, simultaneously when high pressure steams in the oxygen container moulding, the honeycomb state that forms is better, density is that 170Kg/m3, thermal conductivity factor are that 0.07W/m2.K, compression strength are that 3.5MPa, rupture strength are that 2MPa, air sound transmission loss 30dB, fire endurance were greater than 1.5 hours, both formed fire prevention, waterproof, anticorrosion, sound insulation, good heat insulating, the life-span is long, cost is low, the fiber cement coal ash foam battenboard of in light weight, elasticity and good toughness.
Embodiment 2: in step 1 flyash 85%, cement 8%, fiber 4.0% and 1.8% even mixing of adhesive are put in the reaction vessels, add blowing agent 1.2% again; Steam 3 hours evaporates to dryness in the oxygen container for the 0.5MPa high pressure at saturation vapour pressure, step 2 with 3 with embodiment 1 in identical.
