B. adopt gas concrete to make base material, the decorative cover horizontal of base material is made progress, the spray aqueous solutions of polymers closes to full on the decorative cover of base material, adopt grinder on the decorative cover of base material, to carry out grinding simultaneously, make its decorative cover smoothly closely knit, with the decorative cover oven dry or the air dry of base material, obtain having the decoration-free aerated concrete wall material of polymerization concrete layer again.
The present invention can further include following steps:
D. spray paint or organic resin on the decorative cover of decoration-free aerated concrete wall material in step B, or carry out parian, granite processing is handled, and obtains having the decoration-free aerated concrete wall material of polymerization concrete layer and dope layer.
In the described steps A, high molecular polymer is a polyvinyl alcohol, and in the ratio prepared polymer aqueous solution of polyvinyl alcohol and water weight ratio 1:8.
Among the described step B, when spray aqueous solutions of polymers on the decorative cover of base material, add cement or coloured cement simultaneously, and adopt grinder on the decorative cover of base material, to carry out grinding.
By technique scheme, the invention has the beneficial effects as follows:
1. core of the present invention is to utilize after the permeability of the high molecular polymer aqueous solution and the dehydration no longer the stability of hydrolysis that polymerisation is carried out on comparatively loose surface, but forms a kind of netted compactness and the degree of adhesion of fibre structure to improve substrate surface.Utilize the chemical stability of high molecular polymer and the interior function of inhaling of infiltration of the aqueous solution, substrate surface is strengthened processing, and the top layer after the polishing is tending towards closely knit through polymerisation, forms a surfacing, highly polished, waterproof, be difficult for cracking and adhesive power is good exempts from the decorative surface layer plane.Also can do further to decorate to handle as required in factory.
2. the present invention introduces and to exempt to decorate notion, and be convenient to carry out the batch production deep processing and exempt on-the-spot trouble of decorating again, because materials for wall of the present invention surface is through grinding, structured size, site operation is convenient, the planeness height of wall construction.
3. surfacing of the present invention can be carried out diversified deep processing according to designing requirement, and the surface can be parian, granite effect, also can be true mineral varnish effect, common coating effect.
4. the present invention is applicable to the building construction of frame construction, except that intensity own, can add steel mesh when group is built, thereby be specially adapted to highrise building.
