Abstract
The invention discloses an anti-aging long-service-life autoclaved aerated concrete block. Free hydroxide radicals in cellulose are sealed by acetylation reaction of viscose fibers, so that hydrophobicity and thermal stability are improved; by addition of other effective ingredients according to physical modification methods, durability and dispersibility of the fibers in autoclaved aerated concrete are improved; due to the fact that fluorite slag, attapulgite, cuprammonuium and the like serve as fillers, energy saving, environment friendliness and reduction of energy consumption are realized. Compared with existing aerated concrete blocks, the anti-aging long-service-life autoclaved aerated concrete block has the advantages of evident improvement of thermal insulation and sound insulation performances, aging resistance, long service life, high and low temperature resistance, electromagnetic radiation resistance, high durability and less proneness to cracking in long-term use.
Description
Technical field
The present invention relates to aerated-block technical field, be specifically related to autoclave aerated concrete building block of a kind of ageing-resistant life-span length 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 autoclave aerated concrete building block of a kind of ageing-resistant life-span length and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
The autoclave aerated concrete building block that a kind of ageing-resistant life-span is long, it is characterized in that, be made up of the raw material of following weight part: magnesium soap stone flour 25-27, Fluorite slag 38-40, attapulgite 18-20, castor shell 13-15, cement 4.6-5.1, aluminium powder cream 0.09-0.14, W-Gum 5-7, Zinic stearas 1-2, diacetyl oxide 59-62, coumarone indene resin emulsion 4-6, Oleum Gossypii semen 5-7, copper ammonia fibre 6-8, viscose fiber 7-9, Z 250 2-3, suitable quantity of water.
The preparation method of the autoclave aerated concrete building block that the described a kind of ageing-resistant life-span is long, is characterized in that comprising the following steps:
(1) viscose fiber 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, W-Gum 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 Oleum Gossypii semen dry;
(2) magnesium soap stone flour, Fluorite slag, attapulgite, castor shell 5-8% hydrochloric acid soln are soaked 3-4 hour, washing, to neutral, calcines 4-5 hour at 600-650 DEG C, is cooled to 120-130 DEG C and adds coumarone indene resin emulsion grinding 30-50 minute;
(3) dropped in stirrer by step (2) material, add water stirring pulping, adds step (1) material, copper ammonia 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 viscose fiber, 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, with Fluorite slag, attapulgite, copper ammonia fibres etc. are filler, energy-conserving and environment-protective, decrease energy consumption, and obtained aerated-block is heat insulation all good with sound-proofing properties, more existing aerated-block is significantly improved, the ageing-resistant life-span is long, high and low temperature resistance is excellent, anti-electromagnetic radiation is good, life-time service not easily divides good endurance.
