Abstract
The invention discloses a straw ash wall thermal insulation material. The straw ash wall thermal insulation material comprises the following materials: 50-60% of straw ash, 10-15% of sierozem, 25-35% of cement, 0.8-1% of hydroxypropyl methyl cellulose, 0.3-0.5% of hydrophobic powder, 0.3-0.5% of concrete anti-vibration fibre, and 0.5-1% of latex powder. The straw ash wall thermal insulation material uses waste of a plant straw thermal power plant as main material to produce the wall thermal insulation material; the wall thermal insulation material can be prepared to be mortar as an outer wall thermal insulation coating, also can be processed to be a thermal insulation brick or plate which is built on the wall or adhered on the wall, and the outside adhered ornamental brick is firm and has service life as long as that of the wall body. According to the straw ash wall thermal insulation material, the pollution of straw ash to natural environment is avoided and energy is saved. The inorganic thermal insulation material has the advantages of good thermal insulation effects, low water adsorption, freezing and thawing resistance, long service life, fire proofing and inflaming retarding performances, low production cost and extensive market.
Description
Technical field
The present invention relates to the wall body building material technical field, be specifically related to a kind of stalk ash wall heat insulation material and preparation method thereof.
Background technology
At present, the lagging material that is used for various bodies of wall adopts benzene plate, granular polystyrene usually; The heat-insulation and heat-preservation material; Rock wool heat-preservation plate and phenolic aldehyde heat preserving plate, not enough below said product and technology exist, though 1, benzene plate or extruded sheet heat insulating effect be relatively good; But it is poor that its deficiency is a fire resistance, and the particularly low wind suction prevention of the Wind-Pressure Resistance of Highrise buildings thermal insulation layer is dangerous.The glue that is used for outer sticking benzene plate with fixing be that macromolecular material is processed with the plastics nail that expands, As time goes on will wear out becomes fragile, durable years is shorter, use properties not with the same life-span of body of wall.When thermal insulation layer will cause very big harm to The Surroundings in Cities safety during along with demolishing buildings; Increased the pressure of waste to urban environment; Paste the construction requirement of ornamental brick outside outer sticking benzene plate can not satisfy on building exterior wall face, if presence of fire or buildings surpass 20-30 years, assembly glue and plastic expansion have been pinned to meeting hardening working life; Become fragile; Make to be attached to outer field ornamental brick and to come off and cause danger, therefore, the exterior decoration of sticking benzene plate is a coating outside in the world and provincial standard, all requiring.Moreover, the Construction Quality Control difficulty of this lagging material is bigger, and operating efficiency is lower, uses sheet material owing to there is seam the cold bridge heat bridge sternly not occur, and the expandable nail of use can make wall crazing and infiltration, influences construction engineering quality.2, be that the benzene plate is ground into about 20-30 order particles with granular polystyrene as lagging material, add cement again and tackiness agent is mixed and made into, granular polystyrene is made the thermal insulation system of wall thermal insulating and is generally formed by three layers; Putty powder, prime coat and top coat layer, it mainly is made up of organic materials; Its shortcoming is that heat insulation and preservation effect is poor, aging resistance, wetting ability; Performance such as resistance to compression and folding strength is also poor, does not reach the requirement of coating engineering and environmental protection and energy saving, and the rock wool heat-preservation board production technology is complicated; Very big to human harm, the drawback same with the benzene plate arranged in intensity, Wind-Pressure Resistance, Construction Quality Control difficulty etc. aspect many, and the high most users of production cost are difficult to accept.
Summary of the invention
The purpose of this invention is to provide a kind of stalk ash wall heat insulation material, this material environment friendly is nontoxic, utilize waste and save energy, and same life-span of performance and body of wall, and good heat insulating and flame retardant effect are arranged, its intensity, antidetonation, performance such as weather-proof all is superior to existing lagging material.The present invention also provides its preparation method.
For realizing above-mentioned purpose, stalk ash wall heat insulation material of the present invention is to form with following material:
Stalk ash 50-60%, grey calcium 10-15%, cement 25-35%, Vltra tears 0.8-1%, hydrophobic powder 0.3-0.5%, concrete antidetonation fiber 0.3-0.5%, latex powder 0.5-1%.
Stalk ash preparation method of wall heat insulating material:
Choose the straw ash and account for 50-60% of material gross weight; Get the grey calcium 10-15% of weight of material, Vltra tears 0.8-1%, concrete antidetonation fiber 0.3-0.5%; Latex powder 0.5-1%; 0.3-0.5%, No. 425 silicate cements 25-35% of hydrophobic powder, above-mentioned material go into stirrer stir quantitative package finished product.
The preparation method of stalk ash wall insulating brick:
1, gets stalk ash wall heat insulation material finished product, add water 60%, go into stirrer and stir by weight of material;
2, coldmoulding with the lagging material coldmoulding that stirs, is processed plate or brick;
3, send into stoving oven, temperature is controlled at 80-100 ℃, and oven dry in 12-14 hour is finished product.
The present invention is the wall heat insulation material that utilizes the dead meal of straw heat power plant to produce for major ingredient, can be made into mortar and does the exterior-wall heat insulation coating, also can be processed into insulating brick or sheet material; Build by laying bricks or stones on the body of wall or stick on the body of wall, paste outward ornamental brick firm and can with the same life-span of body of wall, the present invention had both solved the pollution of stalk ash to physical environment; Practiced thrift the energy again, because of it is an inorganic heat insulation material, high insulating effect; Water-intake rate is low, freeze-thawing resistant, long service life; And fire protection flame retarding, production cost is low, extensive market.
Embodiment:
Stalk ash preparation method of wall heat insulating material:
Choose the straw ash and account for 50% of material gross weight, get the grey calcium 15% of weight of material, Vltra tears 1%; Concrete antidetonation fiber 0.5%, latex powder 1%, hydrophobic powder 0.5%; No. 425 silicate cements 32%, above-mentioned material go into stirrer stir quantitative package finished product.
The preparation method of stalk ash external wall body thermal insulation brick:
1, gets stalk ash wall heat insulation material finished product, add water 60%, go into stirrer and stir by weight of material;
