Abstract

The invention discloses a corrosion-resistant autoclaved aerated concrete block. The autoclaved aerated concrete block has the advantages that free hydroxyl in cellulose is blocked by subjecting pineapple fibers to acetylation, so that hydrophobicity and thermal stability of the pineapple fibers are improved; other active ingredients are added according to a physical modification method, so that durability and dispersibility of the fibers in autoclaved aerated concrete are improved, strength, apparent density and corrosion resistance of the block are enhanced by added graphite fibers, and the autoclaved aerated concrete block is resistant to corrosion, stable in chemical performance, excellent in physical performance and the like. A manufacturing method of the corrosion-resistant autoclaved aerated concrete block is simple in technology, high in efficiency and free from discharge of three wastes, thereby being remarkable in economic benefit and social benefit.

Description

One is corrosion-resistant adds autoclave aerated concrete building block and preparation method thereof
Technical field
The present invention relates to aerated-block technical field, be specifically related to a kind of corrosion-resistantly add autoclave aerated concrete building block and preparation method thereof.
Background technology
As one of the important kind of novel wall material, autoclave aerated concrete building block has the many merits such as good effect of heat insulation, fire resistance are good, sound insulation, light weight, environmental protection compared with traditional clay vitrified brick.But, air-entrained concrete building block cubic deformation coefficient is bigger than normal, low strength, water-intake rate are large, and when building into body of wall by laying bricks or stones, easily there is crack in body of wall, coat of plaster easily produces big area be full of cracks, hollowing and obscission, show obvious fragility, hinder further application and the popularization of autoclave aerated concrete building block to a certain extent.Fiber is just widely used in traditional normal concrete goods as a kind of good cement matrix strongthener from 20th century, and its correlation theory have also been obtained comparatively sufficient and deep research.But because autoclave aerated concrete building block is in industrialization production process, general employing steel wire carries out excision forming to the gas concrete after initial set, mix too much fiber to affect to some extent the cutting of gas concrete, fiber effect in steam-pressing aero-concrete is made not to be remarkable especially, hinder its range of application in autoclave aerated concrete building block, also have a strong impact on the product quality and performances of autoclave aerated concrete building block.
Summary of the invention
Object of the present invention is just to provide and a kind of corrosion-resistantly adds autoclave aerated concrete building block and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
One is corrosion-resistant adds autoclave aerated concrete building block, it is characterized in that, be made up of the raw material of following weight part: basalt 39-40, powdered iron ore 20-23, titanium gypsum 14-16, wood chip 15-17, cement 4.4-4.9, aluminium powder cream 0.06-0.08, machine oil 4-6, diacetyl oxide 55-57, poly-Union carbide A-162 3-5, calcium lignin sulphonate 0.6-0.8, Sunmorl N 60S 0.4-0.6, Sodium Silicofluoride 0.5-0.7, graphite fibre 6-8, pina fibre 7-9, suitable quantity of water.
The described a kind of corrosion-resistant preparation method adding autoclave aerated concrete building block, is characterized in that comprising the following steps:
(1) pina fibre is put into baking oven in 105 DEG C of dry 1-2 hour, put into retort with pre-steaming 20-40 minute simultaneously, add diacetyl oxide, Sodium Silicofluoride stirring and evenly mixing leaves standstill 3-5 hour, then 100-140 DEG C of reaction 2-3 hour is heated to, dry to neutral with clear water rinsing, spray vaporific machine oil dry;
(2) basalt, powdered iron ore, titanium gypsum, wood chip 5-8% hydrochloric acid soln are soaked 3-4 hour, washing, to neutral, calcines 4-5 hour at 650-730 DEG C, is cooled to 120-130 DEG C and adds poly-Union carbide A-162 grinding 30-50 minute;
(3) dropped in stirrer by step (2) material, add water stirring pulping, adds step (1) material, graphite fibre stirs 2min, add cement mixing 1min, then add aluminium powder cream and other remaining components and stir 30s and obtain slurry, and ratio of water to material is 0.53;
(4) slurry that step (3) is obtained is entered mould, leaving standstill gets angry just supports 2-4 hour, and excision exceeds mould part, and reactor is put in the demoulding, and control temperature 150-170 DEG C is carried out high-temperature steam curing 8-12 hour, discharging.
The present invention has following beneficial effect: the present invention encloses hydroxyl free in Mierocrystalline cellulose by carrying out acetylization reaction to pina fibre, improve hydrophobic performance and the thermostability of material, physical modification method is coordinated to add other effective constituent again, improve fiber weather resistance and dispersiveness in steam-pressing aero-concrete, the graphite fibre added adds the intensity of building block, apparent density and erosion resistance, add other effective constituents simultaneously, obtained building block has corrosion-resistant, stable chemical nature, the features such as physicals is superior, its technique is simple, efficiency is high, without three wastes mass emissions, there is significant economic benefit and social benefit.
