Abstract
The present invention relates to a kind of cement core plates and preparation method thereof, include following component by weight：50 parts of sulphate aluminium cement；25 parts of water；1 part of polyacrylonitrile fibre；0.15 part of edible seaweed powder；0.05 part of 0.25 part of calcium stearate and sodium tripolyphosphate, the formula is reasonable, and cost of material is low, is easy to buy, and cementitious core plate steel plate corrosion intensity obtained is weak, phenomena such as without anti-halogen, alternative magnesia cement plate.
Description
Technical field
The invention belongs to building material fields, and in particular to a kind of cement core plate further relates to the preparation method of cement core plate.
Background technology
Magnesia cement plate is mainly used in construction and decoration field, more representational product have Magnesite thermal insulation board for outer wall,
Magnesite fire-proof door panel, magnesite hollow foamed matter partition plate, foaming fireproof plate etc., in addition, magnesite vent stack, magnesite ventilation duct
Road, sandwich color steel plate also occupy quite a few market.But contain magnesia, magnesium chloride in magnesia cement board raw material, with
The requirement of national environmental protection, large quantities of magnesia producers stop factory, cause the magnesia supply of material at this stage in short supply, the later stage is with national environmental protection power
The reinforcement of degree, the magnesia supply of material may still can have problem.Therefore, it is badly in need of a kind of cement core plate without using magnesia, it can
To solve the problems, such as raw material inadequate supply well.
Invention content
In view of this, one of the objects of the present invention is to provide a kind of cement core plate, raw material is easily purchased, cheap；This
The second purpose of invention is to provide a kind of preparation method of cement core plate.
For achieving the above object, the present invention provides the following technical solutions：
1, a kind of cement core plate includes following component by weight：50 parts of sulphate aluminium cement；25 parts of water；Polypropylene
1 part of nitrile fiber；0.15 part of edible seaweed powder；0.05 part of 0.25 part of calcium stearate and sodium tripolyphosphate.
Preferably, the polyacrylonitrile fibre length is 2~3cm.
2, a kind of preparation method of cement core plate is stated, by the sulphate aluminium cement, polyacrylonitrile fibre, edible seaweed of formula ratio
Powder, calcium stearate, sodium tripolyphosphate sequentially add in stirring, and water is then added, and stir 3~5 minutes, and foam is added later and carries out
Foaming, is stirred for 3~5 minutes, after foams mix is uniform, and slurry is mated formation into mold, and making sheet is carried out.
The beneficial effects of the present invention are：A kind of cement core plate of disclosure of the invention, raw material which uses
For sulphate aluminium cement, instead of the magnesium chloride and magnesia of raw material inadequate supply, and the cost of material of the formula is lower, existing
Stage sulphate aluminium cement price is at 800~1000 yuan/ton, and magnesia price is at 800~1400 yuan/ton, and magnesium chloride is practical
1500 yuan/ton of price.Raw material are easily bought, and the sulphate aluminium cement that cement core plate uses has sale, market in Sichuan, Kweiyang
Range is big, is easy to buy；Magnesia uses the magnesia of Haicheng, the chlorination in the Qinghai that magnesium chloride uses substantially substantially
Magnesium, market scope is narrow, and purchasing channel is single.
It is weak to steel plate corrosion intensity using cement core plate made from inventive formulation from the point of view of product quality, without anti-halogen etc.
Phenomenon.And the easily anti-halogen of magnesia cement plate, have an apparent corrosion to timber and steel plate, cement core plate without anti-halogen phenomenon, to timber and
The corrosion of steel plate is relatively weaker.
Specific implementation mode
The preferred embodiment of the present invention will be described in detail below.
Embodiment 1
A kind of cement core plate includes following component by weight：50 parts of sulphate aluminium cement；25 parts of water；Polyacrylonitrile
1 part of fiber；0.15 part of edible seaweed powder；0.05 part of 0.25 part of calcium stearate and sodium tripolyphosphate.
Preparation method is as follows：By the sulphate aluminium cement of formula ratio, polyacrylonitrile fibre, edible seaweed powder, calcium stearate, three
Polyphosphate sodium sequentially adds in stirring, is then added water, stirs 3~5 minutes, and foam is added later and foams, it is stirred for 3~
5 minutes, after foams mix is uniform, slurry was mated formation into mold, and making sheet is carried out.
In the present embodiment, the fibre length of edible seaweed powder is 2~3cm.
Cement core plate fire protecting performance obtained meets state compulsory standard GB 12955-2008 requirements.
Other indexs and magnesia cement plate are compared, the results are shown in Table 1.
Table 1, cement core plate results of property
It can thus be seen that being prepared using the method for the present invention, cement core plate cost is lower, and easy purchase, product quality is not
Easy anti-halogen, and it is weak to steel plate corrosion intensity, only intensity is poor compared with magnesia cement plate, and brittle, foamed time is slightly longer, needs 5 days, and water chestnut
The curing time of magnesium core plate is 3 days.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
