Abstract

The invention discloses an autoclaved aerated concrete block with ultrahigh sound insulation performance. The autoclaved aerated concrete block is prepared from components in parts by weight as follows: 55 parts of straw ash, 25 parts of cement, 5 parts of clay, 6 parts of blast furnace slag, 4 parts of limestone, 0.8 parts of aluminum powder, 2.5 parts of a foaming agent, 1.5 parts of a desiccant, 1.5 parts of sodium bicarbonate, 3 parts of calcium stearate, 0.6 parts of chlorinated paraffin, 3 parts of cellulose ether, 0.6 parts of polypropylene fibers, 3 parts of polysulfide and 55 parts of industrial wastewater. The autoclaved aerated concrete block with ultrahigh sound insulation performance solves the problem of large resource consumption of the conventional hollow bricks prepared from cement and clay, has a sound insulation function and is environment-friendly, low in manufacture cost and good in effect.

Description

A kind of superpower sound insulation aerated bricks

Technical field

The present invention relates to hollow brick field, particularly belong to a kind of superpower sound insulation aerated bricks.

Background technology

Hollow brick is the main material of body of wall that building trade is conventional in recent years, due to light weight, consumes the advantages such as former material is few, has become First the product recommended for construction sector of country.Hollow brick is compared with solid brick, can save substantial amounts of soil soil and combustion of baking bricks Material, alleviates hauled weight；Labor intensity when alleviating brickmaking and build by laying bricks or stones, accelerating construction progress；Alleviate building deadweight, increase and build Build the number of plies, reduce cost.Hollow brick is usually by clay and cement production systD, and the molding after suppressing out by brickmaking machine is hollow Brick, needs to can be used as construction material after the maintenance of the time of one and uses.Along with the development of building industry, to hollow brick Demand is increasing, and occurs the hollow brick of various function on market, and owner is more and more higher to the requirement of building, such as The problems such as waterproof, anticorrosion, anticracking are increasingly paid attention to, and clay and cement, cost is high, does not meets resource-effective principle, day by day Do not adapt to the demand of society.

Summary of the invention

It is an object of the invention to provide a kind of superpower sound insulation aerated bricks, solve existing hollow brick and be made up of cement and clay and disappear Cost source is big, has sound insulation effect, environmental protection simultaneously, and cost of manufacture is low, effective.

Technical scheme is as follows:

A kind of superpower sound insulation aerated bricks, is made up of the following component of following weight portion meter: straw ash 50-60 part, cement 20- 30 parts, clay 4-6 part, blast-furnace cinder 5-8 part, limestone 3-5 part, aluminium powder 0.5-1 part, foaming agent 2-3 part, desiccant 1-2 part, Sodium bicarbonate 1-2 part, calcium stearate 2-4 part, chlorinated paraffin 0.5-0.8 part, cellulose ether 2-4 part, polypropylene fibre 0.5-0.7 Part, TR sealant 2-4 part, industrial wastewater 50-60 part；Its preparation method comprises the steps:

(1) calcining 3-4h at 1000-1200 DEG C after clay, blast-furnace cinder, limestone mixing, addition is equivalent to above-mentioned The calcium stearate of calcined material weight 2-3%, 3-4% sodium bicarbonate agitating uniform, dry, dry temperature and be 50-70 DEG C, Drying time is 5-10min；Enter back into high-temperature region to dry, dry temperature and be 150-200 DEG C, drying time 10-20min, It is ground into powder again；

(2) cement, straw ash, aluminium powder, cellulose ether, polypropylene fibre are put into blender and be mixed and stirred for uniform 5- 10min, is slow added into industrial wastewater, finally continues stirring 20-40min with blender；

(3) product obtained in above-mentioned steps (1), (2) is mixed with other remaining ingredients, gained mixed slurry pour into Mold forming, after at 60-70 DEG C precuring 3-5h, through the demoulding, be hoisted to cutting part cutting, obtain building block base.

A kind of superpower sound insulation aerated bricks, is made up of the following component of following weight portion meter: straw ash 55 parts, cement 25 parts, Clay 5 parts, blast-furnace cinder 6 parts, limestone 4 parts, aluminium powder 0.8 part, foaming agent 2.5 parts, 1.5 parts of desiccant, sodium bicarbonate 1.5 Part, calcium stearate 3 parts, chlorinated paraffin 0.6 part, cellulose ether 3 parts, polypropylene fibre 0.6 part, TR sealant 3 parts, industrial wastewater 55 Part.

The raw material of the present invention uses cheap in a large number, and discarded resource, by rational proportioning raw materials, by industrial or agricultural The waste's reclamation produced, reaches the further improvement of properties of product simultaneously, owing to the aerated bricks hole ratio of the present invention is high, Have preferable assimilation effect, environmental protection to sound wave, cost of manufacture is low, effective.
