Abstract

The invention discloses a preparation method for a composite foam concrete plate and relates to the technical field of thermal insulation of buildings. Portland cement and high early strength cement are used as based cementitious materials, fine sand is used as aggregate, coal ash is used as admixture, and an early strength agent, a colloid agent, wood fibers and polyethylene fibers are used as additives, and an inorganic fire prevention and thermal insulation plate is prepared by the following steps of: preparing a foam aqueous solution by physical and chemical methods by using a foaming agent aqueous solution, mixing the foam aqueous solution, and mixture of the Portland cement, the high early strength cement, the fine sand, the coal ash, the early strength agent, the colloid agent, the wood fibers and the polyethylene fibers, pouring, and curing. Under the action of the early strength agent, the early strength time of the foam cement plate can be shortened quickly; and by the process, particularly the actions of the additives such as organosilicone and rubber powder, the water absorption of the composite foam cement plate can be reduced, and the toughness of the composite foam cement plate can be improved.

Description

The preparation method of composite foaming cement plate
Technical field
The present invention relates to the building heat preservation technical field.
Background technology
In recent years, the hard polyurethane foam material all is widely used in each field as lagging material.But can only reach the B1 level because its fire resistance is generally the highest.
The main raw material that the composite foaming cement plate of the first-generation adopts is quick hardening sulphoaluminate cement, and it has the fast advantage of early strength, but the later strength decay is also fast, makes building have certain risk the work-ing life of directly impact building.It is main raw material that composite foaming cement plate afterwards adopts high-grade silicate cement, although the later strength decay slowly, early strength is slow, makes the generation cycle stretch-out, is unfavorable for enhancing productivity, and has also taken a large amount of production mould and industrial land.
Summary of the invention
The present invention seeks to propose a kind of fire-protection rating and reach fast, the later strength of A level, the early stage intensity slowly preparation method of composite foaming cement plate that decays.
The inventive method is: first silicate cement, rapid hardening cement, fine sand, flyash, hardening accelerator, gum agents, wood fibre and polyethylene fibre are mixed, then add entry, mechanical stirring is even, adds foaming agent water solution again, restir, pour rapidly the compound that stirs into mould, at normal temperatures, make its free foaming, after 24 hours, natural curing is placed in form removal, gets final product.
The mass ratio of above-mentioned silicate cement, rapid hardening cement, fine sand, flyash, hardening accelerator, gum agents, wood fibre, polyethylene fibre, whipping agent and water is 140~200 ︰, 80~120 ︰, 30~40 ︰, 20~30 ︰, 3.5~6 ︰, 3~3.5 ︰, 0.03~0.05 ︰, 0.001~0.002 ︰, 0.8~1.7 ︰ 130~200.
The present invention adopts silicate cement and rapid hardening cement as based cementitious material, with fine sand for gathering materials, take flyash as adulterant, take hardening accelerator, gum agents, wood fibre and polyethylene fibre as admixture, adopt the method for physics and chemistry that the foaming agent aqueous solution is prepared into bubble solution, with after the froth foam aqueous solution and silicate cement, rapid hardening cement, fine sand, flyash, hardening accelerator, gum agents, wood fibre and the stirring of polyethylene fibre compound, form inorganic fireproofing heat-insulation board through cast, maintenance again.Because the effect of hardening accelerator, can shorten rapidly the strong time of morning of foam cement plate, because above technique, the particularly effect of the additive such as silicone based and rubber powder can reduce the water-intake rate of composite foaming cement plate, improves the snappiness of composite foaming cement plate.
In addition, foaming agent water solution of the present invention is formed by whipping agent and water mixing, and when described mixing, the mass ratio that feeds intake of whipping agent and water is 70~80 ︰ 20~30.
Embodiment
One, weighing: take by weighing respectively silicate cement 140~200kg, rapid hardening cement 80~120 kg, fine sand 30~40 kg, flyash 20~30kg, hardening accelerator 3.5~6kg, gum agents 3~3.5kg, wood fibre 0.03~0.05kg, polyethylene fibre 0.001~0.002kg, whipping agent 0.8~1.7kg, water 130~200kg.
More than each the material all by commercially available acquisition.
Two, preparation foaming agent water solution:
Whipping agent and 0.2kg water are fully mixed, and it is stand-by to form foaming agent water solution.
Three, siccative mixes:
With silicate cement, rapid hardening cement, fine sand, flyash, hardening accelerator, gum agents, wood fibre and polyethylene fibre mixing and stirring, stand-by.
Four, make the composite foaming cement plate:
The siccative that mixes is mixed with residue water, in mechanical means, stirred 1~2 minute, until evenly, it is molten to pour whipping agent into again, restir 10~15 seconds after stirring-head stops to stir, is poured rapidly the compound that stirs into mould, any pressure in addition not, make its free foaming, at normal temperatures, after 24 hours, natural curing 28 days is placed in form removal.
Five, cutting, packing:
After maintenance is finished, the composite foaming cement plate is needed size cutting, then packing by the user.
