Abstract

The invention discloses an aging-resistant flexible aerated building block and a preparation method therefor. The aging-resistant flexible aerated building block is prepared from the following raw materials in parts by weight: 100-120 parts of desert sand, 20-30 parts of ceramic polished slag, 35-45 parts of ordinary Portland cement, 8-10 parts of poultry bone meal, 4-6 parts of waste/used tire rubber powder, 3-5 parts of white clay for papermaking, and the like. According to the aging-resistant flexible aerated building block and the preparation method therefor, the added raw materials such as organosilicon microspheres, the waste/used tire rubber powder, calcium rosinate and the like are used in a compounded manner, so that the water absorption rate of aerated bricks can be greatly lowered, the aerated bricks can have excellent water resistance and are not prone to wetting, and thus, the mildew resistance is relatively high; and in addition, the aerated building block disclosed by the invention further has relatively high compressive strength and bending strength, long service life, wide application range and broad market prospect. According to the aging-resistant flexible aerated building block and the preparation method therefor, a compounded plasticizer which is prepared from added diisodecyl phthalate, beta-diketone and ammonium polyphosphate is matched with an ethylene-vinylacetate copolymer, so that the aging resistance and processing performance are improved while mechanical properties are improved, and the flexibility is improved; and meanwhile, ammonium polyphosphate plays a role in condensing a phase.

Description

Flexible aerated-block of a kind of ageing resistance and preparation method thereof
Technical field
The present invention relates to building material technical field, is more particularly flexible aerated-block of a kind of ageing resistance 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.
