Abstract
The invention belongs to a kind of building water-proof heat-insulating powder and production method.Directly adopt that waste from a factory---the granulation coal ash of slag tapping boiler is made raw material, a kind of as properties-correcting agent with in stearic acid or its calcium, zinc, the aluminium salt adopts dry method coating production technique to carry out modification and handles, and once makes this product.Therefore, it is wide that the present invention has raw material sources, and Production Flow Chart is short, technology advanced person, less investment, energy consumption are extremely low, and cost and like product are relatively low by 20～50%, and characteristics such as the waterproof and heat-insulating performance is good, the raw materials cost and the energy consumption height of like product have been overcome, the disadvantage that Production Flow Chart is long, investment is big.
Description
The invention belongs to material of construction, particularly a kind of powder-type material of construction that can be used for waterproof and heat insulation (insulation).
At present, generally be applied to building roofing and other position waterproof, heat insulation powder-type material in the society, though it is poor to have overcome the temperature tolerance of asphalt felt and the existence of other organic waterproof material, easily trickling, be full of cracks and aging, disadvantages such as work-ing life is short, and effect is better, is that CN1056513A " heat insulation town pigment and production method thereof " and application number are that 92108070.0 " a kind of thermal insulation and water-proofing powder and production method thereof " just belongs to this class waterproof, lagging material as notification number.But the base of this class waterproof and heat-proof powder nuclear is mainly light calcium carbonate etc., these raw materials generally all need be through obtaining the courses of processing such as ore reduction, calcining, ashing, carbonization, dehydration, drying, so there are defectives such as energy consumption height, facility investment and cost height, even directly adopt industrial light calcium carbonate, equally also there is the cost problem of higher, thereby is unfavorable for further reducing the cost of engineerings such as roofing.In order to address this problem, Tongji University has invented " compound water-proof building material and production method thereof " and (CN1047880A) has reached " building waterproofing powder and production method thereof " (CN1044669A).Both all are to be main raw material with cinder and coal ash, adopt the wet processing flow process.Wherein the former adds sufficient material, water, soap slag or the dregs of fat under the alkali factory in raw material, behind mixing and the input ball mill grinding, forms through dehydration, drying, pulverizing etc. again; The latter adds the ξDian Wei conditioning agent and water is made mixed slurry in flyash, mix stirring with the emulsion that adopts tensio-active agent, auxiliary agent and water to be mixed with again, makes the water-proofing powder slurry; Make finished product again through dewatering, drying.This is that the wet process technique of main raw material still exists defectives such as energy consumption height and long flow path, manufacturability difference with flyash.
The objective of the invention is to; granulation coal ash (or claiming grain slag) with slag tapping boiler is a raw material; adopt the membrane wrapping modified processing method of dry method; the disposable waterproof and heat-proof powder product that makes is simplified flow process to reach, saves investment, is cut down the consumption of energy and cost and purposes such as utilization of waste material and environment protection.
Solution of the present invention is directly to adopt the granulation coal ash of slag tapping boiler to make raw material, adopts a kind of as properties-correcting agent in stearic acid or stearic calcium, zinc, the aluminium salt, and both form through membrane wrapping modified processing in the heating power coating machine; Its method is water ratio to be lower than 5% granulation coal ash and properties-correcting agent is by weight percentage: the granulation coal ash: properties-correcting agent=97～99.5: 0.5～3 ratio successively drops in the coating machine; the powerful stirring in 80～160 ℃ of temperature ranges; make properties-correcting agent evenly be coated on the surface of pelletized coal ash powder securely, export and promptly obtain product of the present invention after cold.When granulation coal ash water ratio≤3%, can after dropping into the heating power coating machine, the granulation coal ash add properties-correcting agent immediately; And when water ratio＞3% and＜can coal ash to be granulated 5% the time in the heating power coating machine, stir dehumidification to handle for some time; behind water ratio＜3%; add properties-correcting agent again; to guarantee heat insulation (insulation) property (doing air-dry in addition or other method drying treatment when water ratio＞5% of granulation coal ash is appropriate to the occasion) of finished product with save energy.
The invention has the advantages that, directly adopt factory to make raw material as the granulation coal ash of the slag tapping boiler of waste residue, its source is wide, and cost is low, and helps the disposal of three wastes and environment protection; Processing method of the present invention, because raw material can be directly used in membrane wrapping modified processing, need not carry out such as: calcining, pulverizing, fine grinding etc. are processing further, and what adopt is the dry method coating process, therefore has the production technique advanced person again, flow process is short, energy consumption is low, cost is than characteristics such as like products low 20～50%; The every performance index of waterproof and heat-proof powder that adopt the present invention to produce all reach the requirement of the Shanghai Q83-87 of the national Shanghai City standard metering management board issue of recommending about hydrophobic powder for building Performance Testing standard.
Embodiment one
Present embodiment adopts the granulation coal ash of the heat power plant's slag tapping boiler after the seasoning as raw material, its water ratio≤3%; With calcium stearate (or Zinic stearas, or aluminum stearate) as properties-correcting agent.With above-mentioned granulation coal ash of 196kg and 4kg calcium stearate, drop in the heating power coating machine, under 100 °～160 ℃ temperature condition and under the rotating speed of 350～500rpm; the powerful stirring 20～30 minutes; carry out membrane wrapping modified processing, material is discharged after qualified on inspection, get product after the cooling.
Embodiment two
It is properties-correcting agent that present embodiment adopts stearic acid.
When water ratio＞3% of granulation coal ash and＜5% the time; earlier granulation coal ash 195kg being dropped into the heating power coating machine stirs separately; drying treatment 5～10 minutes; when water ratio drops to 3% when following; add stearic acid 5kg again; carry out coating about 20 minutes and handle stirring again under 80 °～110 ℃ temperature condition and under the rotating speed of 350～500rpm, material is discharged after qualified on inspection, get product after the cooling.
