Abstract

The present invention discloses a flame retardant and flexible aerated block and a preparation method therefor. The aerated block is prepared by the following raw materials in parts by weight: 100-120 parts of desert sand, 20-30 parts of ceramic polishing residue, 35-45 parts of ordinary portland cement, 8-10 parts of poultry bone powder, 4-6 parts of waste tire rubber powder, 3-5 parts of white mud for paper making, and the like. According to the present invention, combined use of raw materials such as added silicone microsphere, waste tire rubber powder and rosin calcium can greatly reduce the water absorption of the aerated block, provide the aerated block with outstanding water resistance and not prone to get damp, thereby strengthening the anti-mouldy property. Moreover, the aerated block further has stronger compressive strength and flexural strength, a long service life, a wide application range, and a wide market prospect. According to the present invention, an added complex plasticizer composed of di-isodecyl phthalate, [beta]-diketone and ammonium polyphosphate is combined with an ethylene vinyl acetate copolymer, thereby improving the mechanical property and meanwhile improving aging resistance, processability and flexibility; and the ammonium polyphosphate has an effect in a condensed phase.

Description

A kind of flame retardant flexible aerated-block and preparation method thereof
Technical field
The present invention relates to building material technical field, is more particularly a kind of flame retardant flexible aerated-block and preparation method thereof.
Background technology
" autoclave aerated concrete building block " is for main raw material with siliceous material (sand, flyash and containing silicon tailings etc.) and calcareous material (lime, cement), admixture foaming agent (aluminium powder), through the stirring that adds water, hole is formed, the porous silicate goods made by technological processs such as casting, precuring cutting, steam press maintenances by chemical reaction.
Aerated-block is generally divided into two kinds, sand aerated-block and grey aerated-block.The production of air-entrained concrete building block, can utilize the trade wastes such as flyash, CHARACTERISTICS OF TAILINGS SAND and desulfurated plaster in a large number, meet the strategy of developing a circular economy, belong to the novel wall material of national policy encourage growth.But because each enterprise utilizes the difference of local resources condition, therefore starting material chosen and fill a prescription different, what quartz sand (or mine tailing) generally will be utilized substantially to produce is called " sand aerated-block ".As buildings infilled wall, and it is best self heat insulation wall.Aerated-block is also known as making light cinder brick, foamed brick, light partition wall brick; Also make this material can block sound-also known as do acoustic brick, sound insulation brick; Because containing a large amount of air in material, be called again aerated bricks, aerated blocks; Meanwhile, this material has good heat-insulation and heat-preservation fire resistance, also known as making insulating brick, insulating brick, fire proofing tile, energy-saving brick; Most importantly, it is made with concrete, has very high intensity, so its art name is called-air-entrained concrete building block.
