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

technical field [0001] The invention relates to the technical field of building materials, in particular to an aging-resistant flexible aerated block and a preparation method thereof. Background technique [0002] "Autoclaved aerated concrete block" is made of siliceous materials (sand, fly ash and silicon-containing tailings, etc.) After adding water and stirring, the pores are formed by chemical reaction, and the porous silicate products are made through casting molding, pre-curing cutting, autoclaving curing and other processes. [0003] Aerated blocks are generally divided into two types, sand aerated blocks and gray aerated blocks. The production of aerated concrete blocks can use a large amount of industrial waste such as fly ash, tailings sand, and desulfurized gypsum, which is in line with the development of circular economy strategy and is a new type of wall material encouraged by national policies. However, due to the different conditions of local resources used ...
