Description

A kind of high heat preservation performance air-entrained concrete building block
Technical field
The present invention relates to the aerated bricks field, is exactly a kind of high heat preservation performance air-entrained concrete building block.
Background technology
Aerated bricks is the air-entrained concrete building block of producing by the autoclave at high temperature apparatus and process." aerated bricks " can be understood as a simplification or a general title.Its product scope contained should more greatly, adopt the brick product of other various explained hereafter that comprise steam pressure.
Construction market materials for wall used was mainly common brick in the past, and present many advanced areas have been completely forbidden common brick and used.
Existing aerated bricks Development Technology is slow, can't meet the market requirement of diversification.
Summary of the invention
The object of the present invention is to provide a kind of high heat preservation performance air-entrained concrete building block.
Above-mentioned purpose realizes by following scheme:
A kind of high heat preservation performance air-entrained concrete building block, it is characterized in that: it is that raw material by following weight parts makes: Nekal BX 0.04-0.06, magnesium powder 0.003-0.01, triethanolamine oleate 0.04-0.05, cement 4-5, Sumstar 190 0.1-0.3, Vanay 0.002-0.006, ethylene glycol monomethyl ether 0.01-0.03, wood fibre 0.1-0.5, swelling perlite powder 10-20, steel-making slag powder 7-9, kaolin 17-19, alum 1-2, chitosan 0.2-0.4.
Described a kind of high heat preservation performance air-entrained concrete building block is characterized in that:
The preparation method comprises the following steps: after (1) mixes swelling perlite powder, steel-making slag powder, kaolin, alum by weight, under 900-1000 ℃, calcining is after 2-4 hour, take out, cooling, being ground to grain diameter is 1.75mm-1.90mm again, take out, add the ethylene glycol monomethyl ether that is equivalent to material gross weight 1.5-2.2%, the silane coupling agent KH580 of 1.2-1.5%, the Potassium Persulphate of 0.1-0.2%, and suitable quantity of water, after under 100-200 rev/min, stirring mixes in 10-20 minute, granulation, the balling-up particle diameter, at 0.5-1.5mm, obtains the composite minerals particle standby;
(2) take by weight composite minerals particle and all the other all raw materials, stir after 10-20 minute under 50-100 rev/min, then stir 5-8 minute under 100-160 rev/min, take out, obtain mixed slurry;
(3) the gained mixed slurry is poured into the mold moulding, rear precuring, the demoulding, cutting, obtain the building block base;
(4) the building block base is put into to the reactor steam press maintenance, put finished product in storage and get final product.
Beneficial effect of the present invention is: what wood fibre was unordered is distributed in aerated bricks, stops the expansion in crack, has improved the peeling off of this concrete opposing freeze-thaw cycle, separating power and insulated capacity.
