A high-strength partition board with waterproof function

Abstract

The present invention relates to the field of construction materials, and provides a high-strength partition wallboard with a waterproof function. The raw materials of the partition wallboard consist of the following components in parts by mass: 270-370 parts of fly ash, 330-430 parts of perlite, 240-320 parts of water, 250-350 parts of sulphoaluminate cement, 30-35 parts of methyl sodium silicate, 8-12 parts of a polymer binder, 0.15-0.25 parts of boronic acid, 0.35-0.45 parts of a physical foaming agent, 20-25 parts of calcium silicate powder, 8-12 parts of a concrete water reducing agent. The high-strength partition wallboard provided by the present invention realizes water-proof and moisture-proof functions with the effective combination of auxiliaries of the methyl sodium silicate, polymer binder, concrete water reducing agent and the like. After a water soaking test for 40 days, the wallboard is sawed apart for internal examination, thereby showing that water still cannot penetrate into the internal structure of the wallboard. The compressive strength of the partition wallboard reaches 6 kpa, and the surface density of the partition wallboard is only 60 kg / m<2>. With an ordinary technique, heating is needed after moulding, and maintenance for 7 days is required after demoulding before packaging and shipping. But, the high-strength partition wallboard disclosed by the invention does not need to be heated and can be directly packaged and shipped after demoulding. The high-strength partition wallboard provided by the present invention reaches the leading domestic level in various technical standards.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a partition board. Background technique [0002] With the development of society, the country implements the wall reform policy to achieve the purpose of protecting land and saving energy. In recent years, more and more types of new wall materials have appeared in the society, among which there are more applications, such as gypsum or cement lightweight partition boards, color steel plates, aerated concrete blocks, steel wire grid foam boards, small Concrete hollow blocks, gypsum boards, gypsum blocks, ceramsite blocks, sintered porous bricks, shale bricks, solid concrete bricks, PC slabs, horizontal hole concrete wall panels, activated carbon walls, new partition wall panels, etc. [0003] The common problem of new wall materials is that it is difficult to achieve the purpose of waterproof and moisture-proof while ensuring its high strength and high thermal insulation performa...
