Description
Technical field
The invention belongs to building thermal insulation material field, and in particular to a kind of physical foaming cement is incubated board production technology.
Background technology
Since self state's exterior-wall heat insulation uses organic foam warming plate, catch fire repeatedly, given our people's lives and properties
Bring about great losses, therefore, NFA office has issued (65 [2011]) number text, it is desirable to " disabling organic foam warming plate ".
This is filled with powerful motive force to the development of foam concrete heat-preserving plate.With China's wall reform and Building Energy Conservation Policy
Put into effect and implement, and influenceed by building fire, modern Energy Conservation Green Construction is badly in need of excellent thermal insulation performance, sharp useless, lightweight
Non-ignitable insulation material.Foam concrete can meet above-mentioned performance, but there is thermal insulation separation as a kind of new construction material
The problems such as hot property is poor, raw materials consumption amount is larger.
Ultralight foam concrete because porosity is higher, raw material usage is lower, cost is lower, technique is simple, it is green, every
The advantages of sound, antidetonation, fire prevention, enjoys insulation industry to favor.In the prior art, often with it is early strong, soon solidifying special cement (
Based on sulphate aluminium cement, ferrous aluminate cement etc.) it is binder materials, ultralight foam coagulation is prepared using chemical blowing mode
" a kind of foam concrete of extremely-low density and preparation method thereof " disclosed in soil, such as Publication No. CN101508593A, is adopted
Prepared with chemical blowing, molding control is difficult, and is suitable only for the production of prefabrication.On the other hand sulphate aluminium cement is used, should
Cement is special cement, and special cement resource is relatively deficient, and cost is high, and there are endurance issues, hinders ultralight foam and mixes
Coagulate the development of soil.The Novel foam concrete prepared using physical blowing has good workability, not only can be prefabricated but also can be cast-in-place,
Great advantage is shown for another example disclosed in Publication No. CN102515664A " low-cost ultra low density foam concrete ", though
Using raw material such as the flyash of Portland cement, I or II, graining blast-furnace cinder micro-powders, but the Physical prepared is ultralight
Foam concrete needs realize that commercially available swelling agent species is various, and quality is uneven, and passes through mostly by adding swelling agent
Cross high-temperature firing to form, not only cost height, price, preparation high energy consumption, and quality also has dispute, practicality is poor.
The content of the invention
It is an object of the invention to provide a kind of production efficiency height, the physical foaming cement warming plate production of good product performance
Technique.
Based on above-mentioned purpose, the present invention uses following technical scheme：A kind of physical foaming cement is incubated board production technology, step
Suddenly it is：
（1）Common portland cement, Smecta mineral admixture, compound additive are measured, stirs and must consolidate in advance
Not bleeding, not stratified slurry is made in body material, the wet-milling that adds water；
（2）High-speed stirred after fiber is added in slurry to disperse；Then the formation of foam bubble that diameter is less than 0.3 millimeter is added
Body；
（3）By step（2）In obtained foam using sheet material is cut into after mould molding, maintenance, the demoulding, by polyphosphazene polymer
Compound water-proof emulsion uniformly penetrating enters in the micropore of sheet material, and artificial drying or natural air drying are produced.
Preferably, step（1）The mass ratio of reclaimed water and solid material（0.6~1.0）: 1, time of wet-milling slurrying for 20 ~
60min。
Preferably, step（3）Middle foam is utilized conserves 8h ~ 28d under 20 ~ 100 DEG C of moisturizing constant temperature after die molding process
It is stripped again.
Preferably, step（3）Described in high molecular polymer water-proof emulsion be water proofing property pure-acrylic emulsion, vinyl acetate emulsion（Vinegar
Acrylic emulsion）, styrene-acrylic emulsion（Styrene-acrylate emulsion）And EVA（Vinyl acetate-ethylene copolymer）One kind in emulsion,
1m3The consumption of high molecular polymer water-proof emulsion is 5kg in the sheet material that foam is prepared.
Preferably, step（1）Described in Smecta mineral admixture be composited by metakaolin and flyash,
The mass percent that metakaolin accounts for Smecta mineral admixture is 50% ~ 70%.
Preferably, step（1）Described in compound additive be composited by gypsum and calcium hydroxide, gypsum accounts for compound additional
The mass percent of agent is 40% ~ 60%.
Preferably, step（2）Described in foam be prepared from by foaming agent in foaming machine, the foaming agent be plant egg
White foaming agent.
Preferably, step（2）Described in fiber be neutral alkaline-resisting polypropylene fibre.
Preferably, step（1）Described in solid material the percentage by weight of each material be：Common portland cement 20 ~
100%th, Smecta mineral admixture 0 ~ 75%, surplus is compound additive.
Preferably, step（2）Middle 1m3Contain 0.5 ~ 0.75kg foaming agents, 0.8 ~ 1.5kg fibers in foam.
Compared with prior art, what the present invention was provided has advantages below：
（1）The production technology that the present invention is provided first carries out wet-milling slurrying before fiber is added, and wet-milling repulping rate is fast, it is only necessary to
20 ~ 60min greatly improves production efficiency, reduces production cost with regard to material particles fineness can be made to decline 2 ~ 3 times；And can make
Material is sufficiently mixed, excitation material activity, improves the activity index of material, favourable to improve early stage and later strength；Meanwhile, pass through
The slurry of wet-milling, workability is good, not bleeding, not stratified, and abscess independent completion is realized to subsequent technique, critical work is played
With.
（2）The rapid uniformly penetrating of high molecular polymer water-proof emulsion is entered in the micropore of sheet material, by artificial drying or certainly
After so air-drying, polymer in emulsion will on micro-pore wall conjunctiva, block the passage of pore, insulation can be effectively reduced
The water absorption rate of plate, improves the toughness and intensity of sheet material, prevents sheet material from bursting.
