Partition wallboard of environmental protective lightweight fiber

Abstract

This invention discloses a method for preparing environmentally friendly lightweight fiber wallboard. The raw materials comprise: diffusant 3%, ferrous sulfate 1%, magnesium oxide 20%, magnesium chloride 15%, industrial waste (industrial slag or fly ashes) 31%, and grass powder (pulverized haulm, wheat straw, bamboo leaves or crop straw) 30%. The method comprises: pulping the raw materials, loading into a mold, pressing, flattening, molding, flattening, polishing, demolding, repairing, and examining. The lightweight fiber wallboard has such advantages as high resistance to halogenation and frost, high strength, high anti-shock performance, high sound insulation performance, and high stability.

Description

technical field [0001] The invention relates to a wall material, in particular to an environment-friendly lightweight fiber partition wall board. It can be used as interior walls, insulation panels, decorative panels, prefabricated rooms, fences, etc. of house construction. Background technique [0002] Clay bricks or cement-lime sand bricks have been used as fill walls in construction projects or in building frames. The firing of the above-mentioned clay bricks will destroy the cultivated land, consume energy, and the weight of the wall, the load of the frame is heavy, and the construction cost is high. Therefore, the state expressly stipulates that clay solid bricks are prohibited in urban construction projects, and hollow blocks are gradually used to replace clay. Solid bricks serve as infill walls. Slag or fly ash are often used as fillers when making hollow blocks. Lightweight sandwich Taber boards are also used to fill walls. Although adopting these materials can r...

AI Technical Summary

Problems solved by technology

Although the use of these materials can reduce the weight of the wall, there are still defects in the strength of the slag hollow blocks and the large investment in the production of lightweight sandwich boards, which is not conducive to popularization and use.

At present, try to promote silicon-magnesium boards as filling walls. Although this material is light in weight, easy to obtain and easy to manufacture, it is easy to return to halogen and frost in wet conditions. At the same time, its strength will gradually decrease as time goes on. And poor sound insulation
