Embodiment

[0027] Example: 90 mm thick partition wall board, composed of an inner interlayer of polystyrene heat insulation board with a thickness of 40 mm and two outer layers each 25 mm thick, with non-woven fabric between the outer layer and the inner interlayer. The outer layer is made of the following raw materials in weight fractions:

[0028] Phosphogypsum 90 parts

[0029] 10 parts of magnesium oxide,

[0030] 40 parts of magnesium chloride,

[0031] 32 parts of industrial coal ash,

[0032] 22 parts perlite powder,

[0033] 18 parts of diatomaceous earth,

[0034] 16 parts of sawdust,

[0035] 22 parts of magnesite gelling material.

[0036] The double-drive double-roller extrusion process is adopted, and the production process of the whole board is completed at one time from sizing, main material spreading, and compound repressing.

Abstract

The invention relates to an environmental-friendly light partition board produced by waste ardealite and belongs to the techniques of building materials. The partition board comprises an inner interlayer and two outer layers, wherein the inner interlayer is made of polystyrene heat-insulation heat-preservation board, the two outer layers are arranged outside the two surfaces of the inner interlayer, non-woven fabrics are arranged between the outer layers and the inner layer, and the outer layers are made from the following raw materials according to parts by weight: 90 parts of ardealite, 10 parts of magnesium oxide, 35-40 parts of magnesium chloride, 30-35 parts of industrial coal ash, 20-25 parts of crushed crude pearlite, 14-20 parts of kieselguhr, 14-20 parts of saw timber powder and 20-25 parts of magnesite binding materials. The ardealite is waste generated in production process of phosphatic fertilizer enterprises. According to the environmental-friendly light partition board produced by the waste ardealite, the light partition board is free of toxin, odor and radioactivity, and has the characteristics of shock resistance, large compressive strength, heat insulation, fire protection, good sound insulation effect, water resistance, damp proof, and convenience in construction; the light partition board is mounted by plates or in a combined manner, has the characteristics of capabilities in nailing, sawing, digging, adhering, pasting and the like and is flat and unnecessary to be plastered, and the puttying can be directly carried out.

Description

technical field [0001] The invention belongs to building material technology, in particular to a board. Background technique [0002] Interior decoration partitions, suspended ceilings, floor heightening, frame structure building partitions and other projects in modern buildings are in urgent need of panels with high strength, light weight, thermal insulation and sound insulation, fireproof, waterproof and moisture-proof, and fast construction. Products that fully meet the above requirements are hard to find. Contents of the invention [0003] The purpose of the present invention is to provide an environmentally friendly lightweight partition wall board produced by using waste phosphogypsum. The product is required to have the properties of high strength, light weight, thermal insulation, sound insulation, fireproof, waterproof and moistureproof, and fast construction. [0004] The partition wall panel of the present invention includes an inner interlayer made of polystyr...
