Description

A kind of preparation method of oil resistant aerated bricks
Technical field
The invention discloses a kind of preparation methods of oil resistant aerated bricks, belong to building material technical field.
Background technology
Aerated bricks are " autoclave aerated concrete building block ", and abbreviation aerated bricks are produced by autoclave at high temperature apparatus and process Air-entrained concrete building block." aerated bricks " can be understood as a simplified or general title.Its product model covered The brick product of other various technique productions including steam pressure will be used by enclosing.The advantages of aerated bricks is:1, again Amount is light.The general weight of air-entrained concrete building block is 500~700kg/m3, is only equivalent to clay brick 1/4~1/5, normal concrete 1/5, be lighter one kind in concrete.Dead weight than common brick concrete structure building reduces by 40% or more.2, thermal insulation separation Good in thermal property.The thermal coefficient of air entrained concrete is the 1/6 of normal concrete, and heat-proof quality is significantly better than the clay of 240mm thickness Brick wall body.3, shock resistance is strong.Air entrained concrete light capacity, overall performance be good, earthquake when inertia force it is small, so with certain Shock resistance.4, processing performance is good.Air entrained concrete have good processing performance, can saw, dig, following closely, milling, brill, to construction band Come prodigious convenience with flexibly.5, with certain heat-resisting quantity.Air entrained concrete is when temperature is 600 degree or less, resistance to compression Intensity slightly increases, and when temperature is at 600 degree or so, compression strength when compression strength is close to room temperature, fire protecting performance reaches Country-level fire-protection standard.6, sound insulation value is good.The internal structure image planes packet of air entrained concrete is the same, is evenly distributed a large amount of Sealed porosity, therefore sound absorption qualities not having with common buildings material.7, adaptable.It can be according to local different former Material, different condition are carried out amount body and are made surely.River sand, flyash, ore in sand form etc., adaptation to local conditions may be selected in raw material.Oil resistant aerated bricks, it is main It refer to the special concrete for not chemically reacted with vegetable oil, animal oil and mineral oils, and it capable of being prevented to permeate. In common mechanical industrial processes, flowed due to transmission, metal cutting and grinding splash out come oils, such as certain mineral oil or Vegetable oil etc., most of relative density is small, viscosity is low, penetrating power is strong, it is easy to destroy cohering between aggregate, some oil Substance of the class also containing some meta-acid classes and esters, it is very big to the intensity effect of aerated bricks, and there is also anti-for traditional aerated bricks The problem of oiliness can not be further increased with mechanical property.
Therefore, how to improve traditional aerated bricks oil-resistant characteristic and the shortcomings that mechanical property can not further increase, to obtain The raising for taking more high combination property is problem to be solved.
Invention content
The present invention solves the technical problem of:For traditional aerated bricks anti-permeability performance, oil-resistant characteristic and mechanics The problem of performance can not further increase provides a kind of preparation method of oil resistant aerated bricks.
The technical solution adopted in the present invention is:
A kind of preparation method of oil resistant aerated bricks, specific preparation process are as follows:
(1)It counts in parts by weight, takes 50~80 parts of cement, 10~20 parts of flyash, 20~30 parts of miberal powders, 40~60 parts of stones successively Sand, 40~60 parts of modified coarse aggregates, 10~20 parts of modified fillers, 5~8 parts of water-reducing agents, 60~100 parts of water;
(2)By cement, flyash, miberal powder, quartz sand, modified coarse aggregate, compound compacting agent, modified filler, water-reducing agent and water stir Mixing is mixed, injection molding stands demoulding, obtains adobe;
(3)Adobe heat-insulation pressure keeping is conserved, then through natural curing to get oil resistant aerated bricks.
Step(1)The cement is portland cement, any one in magnesia oxychloride cement or aluminate cement.
Step(1)The miberal powder is ground granulated blast furnace slag, iron ore ground-slag, any one in copper mine ground-slag or float stone miberal powder.
Step(1)The quartz grain fineness number modulus is 2.3~2.6.
Step(1)The preparation process of the modified coarse aggregate is:By hydrofluoric acid and hydrochloric acid by volume 1:5~1:10 stirrings Mixing, obtains nitration mixture, float stone is crushed, and is sieved, obtains float stone slag;By float stone slag and nitration mixture in mass ratio 1:10~1:20 stirrings are mixed It closes, filtering obtains single treatment float stone slag;By single treatment float stone slag and dopamine solution in mass ratio 1:10~1:20 stirrings are mixed It closes, filtering obtains after-treatment float stone slag, is 1 in mass ratio by after-treatment float stone slag and liquor alumini chloridi:30~1:40 mixing Ultrasound is then added dropwise urea liquid precipitation, is aged, filter, washs, dry, obtains modified coarse aggregate.
Step(1)The preparation process of the modified filler is:It counts in parts by weight, by 20~30 parts of rice husks, 20~30 parts Orange peel, 20~30 parts of pear skins, 5~6 parts of biogas slurries, 40~50 parts of kaolin, 60~80 parts of water mixing, fermentation obtain fermentation slurry, will Gained fermentation slurry is evenly laid out in plastic trough, then earthworm is added to plastic trough, and plastic trough is moved into greenhouse and is supported It grows, after cultivation, obtains wormcast, as modified filler.
Step(1)The water-reducing agent is sodium lignin sulfonate, and TH-928 poly carboxylic acid series water reducers or YZ-1 naphthalene series high-efficiencies subtract Any one in aqua.
Step(3)The heat-insulation pressure keeping curing condition is:Pressure is 2~3MPa, and temperature is 160~180 DEG C.
The beneficial effects of the invention are as follows:
The present invention is by the modified coarse aggregate of addition, and in preparation process, first, float stone slag is impregnated by nitration mixture so that corrosion table The pit in face is further expanded, and dopamine solution immersion is then passed through, and neutralizes the nitration mixture Liquid Residue on float stone surface, meanwhile, DOPA Amine is adsorbed on corrosion surface, improves the absorption property on float stone surface, is conducive to later stage aluminum hydroxide precipitation and is effectively filled in In the pit on float stone surface so that the roughness of corrosion surface is improved, and is conducive in mixing process, is slided between coarse aggregate It is dynamic, so that the resistance that system is subject to when being deformed is reduced, meanwhile, the more regular float stone powder specific-surface area detection in surface reduces, The water requirement of wet granulate reduces, and under conditions of identical water, the opposite sliding between slurry particles is more easy, makes slurry Rheological characteristic is effectively improved, and the early strength of product is effectively improved, and after aluminium hydroxide dissolves under cement alkaline environment, shape At alumine hydroxide colloid so that the anti-permeability performance of system gets a promotion, so that the oil-resistant characteristic of system gets a promotion, with Aluminium hydroxide gradually dissolves, and the dopamine activity group on float stone surface is made to expose again, quartz sand that can be in absorption system, floats Stone surface roughness gets a promotion so that mechanical snap is easily formed between coarse aggregate so that the mechanical property of system obtain into The promotion of one step.
