Description
Technical field
The present invention relates to 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 produced by autoclave at high temperature apparatus and process." aerated bricks " can be understood as simplify an or general title.Its product scope contained should be wanted greatly a bit, namely to adopt the brick product comprising other various explained hereafter of steam pressure.
The materials for wall mainly common brick that construction market was used in the past, present many advanced areas have been completely forbidden common brick and have been used.
Existing aerated bricks Development Technology is slow, cannot 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 is realized by following scheme:
A kind of high heat preservation performance air-entrained concrete building block, it is characterized in that: it is obtained by the raw material of following weight parts: 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:
Preparation method comprises the following steps: after swelling perlite powder, steel-making slag powder, kaolin, alum mix by (1) by weight, calcine 2-4 hour at 900-1000 DEG C after, take out, cooling, being ground to grain diameter is again 1.75mm-1.90mm, take out, add be equivalent to material gross weight 1.5-2.2% ethylene glycol monomethyl ether, 1.2-1.5% the Potassium Persulphate of silane coupling agent KH580,0.1-0.2%, and suitable quantity of water, after stirring mixing in 10-20 minute under 100-200 rev/min, granulation, balling-up particle diameter, at 0.5-1.5mm, obtains composite minerals particle for subsequent use;
(2) take composite minerals particle and all the other all raw materials by weight, after stirring 10-20 minute under 50-100 rev/min, then stir 5-8 minute under 100-160 rev/min, take out, obtain mixed slurry;
(3) pour into the mold shaping by gained mixed slurry, rear precuring, the demoulding, cutting, obtains building block base;
(4) building block base is put into 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, improves the peeling off of this concrete opposing freeze-thaw cycle, separating power and insulated capacity.

Described a kind of high heat preservation performance air-entrained concrete building block,
Preparation method comprises the following steps:
(1) after swelling perlite powder, steel-making slag powder, kaolin, alum being mixed by weight, calcine at 900 DEG C after 2 hours, take out, cooling, being ground to grain diameter is again 1.90mm, take out, add the ethylene glycol monomethyl ether, the silane coupling agent KH580 of 1.2%, the Potassium Persulphate of 0.2% that are equivalent to material gross weight 2.2%, and suitable quantity of water, after stirring mixing in 20 minutes under 200 revs/min, granulation, balling-up particle diameter, at 0.8-1.0mm, obtains composite minerals particle for subsequent use;
(2) take composite minerals particle and all the other all raw materials by weight, stir after 20 minutes under 50 revs/min, then stir 8 minutes under 100 revs/min, take out, obtain mixed slurry;
(3) pour into the mold shaping by gained mixed slurry, rear precuring, the demoulding, cutting, obtains building block base;
(4) building block base is put into reactor steam press maintenance, put finished product in storage and get final product.
The volume-weighted average of this building block is 730kg/m
3, good heat insulating, has a large amount of pores and micropore at block interiors, thus has good thermal and insulating performance, and mean value ultimate compression strength is 9.6MPa.
