Abstract
The invention belongs to a kind of heat insulation and waterproofing powder and production method thereof.It is raw material with the light calcium carbonate, makes tensio-active agent and properties-correcting agent respectively with turkey red oil and stearate.Adopt and at first produce the properties-correcting agent carrier, and then the powerful stirring in the heating power coating machine with this carrier and certain proportion raw material, the two step process methods that make the finished product handled thereby carry out the dry state coating.The present invention has that material composition is single, technology is advanced, flow process is short, and the powder coating is complete, firm, energy consumption is low, water proof anti-seepage, heat-resisting, freeze proof, anti-aging and heat preservation and insulation is good.Be applicable to roofing, freeze engineerings such as storehouse and make heat insulation, insulation and WATER REPELLENT.
Description
The invention belongs to a kind of material of construction, particularly a kind ofly be used for roofing, freeze engineerings such as storehouse as pulvis material heat insulation, WATER REPELLENT; Heat insulation, the insulation and the water tight packing that also can be used as other similar engineering and equipment.
At present, in most industry and covil construction, the different processing mode of the general employing of flat roof thermofin and waterproof layer, employing is provided with the ventilating heat-proof layer as thermofin, and waterproof layer then adopts roofing sheet waterproof layer or organic coating waterproof layer or organic sheet waterproof layer etc.Not only cost height of ventilating heat-proof layer is set, and will increases building roof height and supporting power.Adopt roofing sheet or other organic materials waterproof layers, because of the variation of season, temperature is prone to trickling or drawing crack, and easily aged deterioration loses waterproof effectiveness and causes roof leakage.At these disadvantages, the someone has invented a kind of powdered material with hydrophobic nature, is used for building roof as heat insulation and water resistance layer.Promptly belong to this type of technology as " heat insulation town pigment and production method thereof " (CN 1056513A) and " waterproof and heat-proof powder " (CN 1057854A).Though it is one and characteristics such as ageing-resistant that these two inventions have collection heat insulation (insulation), waterproof, but because heat insulation town pigment (CN1056513A) production method is to adopt multiple natural ore powder (being Wingdale, rhombspar and marble flour) to make raw material, add stearic acid or paraffin wax and do compound processing, exist therefore that material composition complexity, manufacturability are poor, long flow path, power consumption height, defective such as efficient is low, cost is high and thermotolerance is low.And waterproof and heat-proof powder (CN1057854A) is to be main raw material with lime carbonate, carries out the solid-liquid phase reaction with lipid acid and additive and makes.Therefore still there are shortcomings such as manufacturability difference and product thermal stability are low.
The object of the invention is to adopt a kind of dry state coating method novel process and new prescription to produce thermal insulation and water-proofing powder, simplifies to reach that raw material is formed, shortened flow process, purpose such as enhance product performance and cut down the consumption of energy.
Solution of the present invention is that the employing light calcium carbonate is a raw material; Adopt wetting, dispersion and the good turkey red oil (C of penetrating quality
17H
32(OSO
3Na) COONa) conduct is a tensio-active agent; And adopt waterproof, lubricated, heat-resisting freeze proof and stable high hydrophobic nature stearate as properties-correcting agent.This class stearate can be one or more in Zinic stearas or calcium stearate, Magnesium Stearate, aluminum stearate etc.Its production technique was divided into for two steps: the first step prepares the properties-correcting agent carrier, in part light calcium carbonate raw material and a certain proportion of tensio-active agent turkey red oil and the hydrophobic nature stearate one or more are mixed stirring in 90 °～110 ℃ temperature ranges, after material fully is uniformly dispersed, standby as the properties-correcting agent carrier.The weight percent of each component is generally in the properties-correcting agent carrier: light calcium carbonate: turkey red oil: stearate=80: 10: 10; Second step, products production.Be by weight percentage: light calcium carbonate: properties-correcting agent carrier=(85～95): the ratio of (5～15) (total amount is 100) drops into both in the heating power coating machine, the powerful stirring under 110 °～160 ℃ temperature condition, carry out the processing of dry state coating, thereby make the thermal insulation and water-proofing powder of indication of the present invention.
Advantage of the present invention is: 1, adopt industrial light calcium carbonate to make raw material, composition is single, epigranular, and stable performance, thereby need not prepare special material, and shortened technical process greatly, reduced facility investment and energy consumption;
2, adopt turkey red oil to make salts such as tensio-active agent and stearic zinc as properties-correcting agent; And adopt preparation properties-correcting agent carrier earlier, and then adopt the dry state coating process to produce the method for product, because the consistency of properties-correcting agent and light calcium carbonate is good, the powder coating is complete, firm, hydrophobic rate height.The stearate coating exceeds more than 40 ℃ than the fusing point of stearic acid or lipid acid rete, and this has just solved effectively, and like product is made roof waterproof, its thermotolerance of lagging material relatively poor (80 ± 2 ℃) is easy to problems such as trickling under comparatively high temps;
3, product of the present invention detects through the unit that has the right such as Research Inst. of Architectonics, Sichuan Prov., Sichuan Inst. of Building Material Industrial Sciences and Zigong City product quality supervision and testing institute, and every index is:
The product appearance white powder
Granularity (100 screen residue %)≤0.5
Pile up unit weight kg/m
3≤ 600
Hydrophobic rate % 〉=99
Thermal conductivity W/mk≤0.07
Watertightness (hydrostaticpressure 0.01mPa) 〉=20 is waterproof round the clock
Thermotolerance .130 ± 2 ℃, the 10h no change
Frost resistance .-30 ± 2 ℃, the 10h no change
Anti-aging (uviolizing) 100 hours no changes
Acid resistance (concentration of hydrochloric acid solution 1.5%) 10 is no change round the clock
Therefore the present invention has the technology advanced person, flow process is short, the raw material composition is single, and the powder coating is complete, firmly; Product hydrophobic rate height, light capacity, thermal conductivity are low, water proof anti-seepage, heat-insulation and heat-preservation and heat-resisting, freeze proof, characteristics such as ageing-resistant performance is good.
Embodiment
Present embodiment adopts Zinic stearas as properties-correcting agent.
The first step, preparation properties-correcting agent carrier: take by weighing light calcium carbonate 80kg respectively, content is turkey red oil and each 10kg of Zinic stearas of 60%, and above material is dropped in the stirrer.Under the temperature about 100 ℃, mix and stir stirrer rotating speed 350 commentaries on classics/per minutes.It is standby promptly to can be used as the properties-correcting agent carrier after take a sample to check, being uniformly dispersed.
Second step, production the finished product: take by weighing light calcium carbonate 180kg, properties-correcting agent carrier 20kg respectively, drop in the heating power coating machine, in 115 °～125 ℃ temperature ranges, to be not less than 500 rev/mins powerful stirring of speed, carrying out the dry state coating handled about 30 minutes, after quick test is qualified, discharge cooling, promptly get the finished product.
