Abstract
The present invention consists of water-proof and leakage pluging paste and thermal insulating paste-two kinds. The first is composed of (by weight portion) 70-90 ports of sepiolite, 5-10 ports of binder and 5-10 ports of water. The second is composed of the first and 10-15 ports of asbestos down powder and particulate pearlite. Said products can be used separately or jointly. It is mainly used in roof, wall, industrial pipeline equipment for thermal insulation, waterproof and pluging leakage. Coefficient of thermal conductivity is 0.020-0.035 W/M.K. There is no leakage under static hydraulic pressure of 6.27 KPa for seven days. The properties of resisistance of heat, freezing and ageing are all well. In addition it also features harmless, low cost and convenient for construction.
Description
The present invention relates to the application of a kind of heat insulating, water-proof plugging material and this kind material.
Existing lagging material and heat insulation waterproof material are more, for example: (1) slag wool goods: have little, the low temperature resistant characteristics of unit weight, but unsuitable high temperature has stimulation to human body skin and respiratory tract.(2) superfine glass wool product, unit weight is little, and thermal conductivity is low, and is low temperature resistant, but it is numerous and diverse to construct, and the adaptive temperature scope is little, high price.(3) asbestos product: unit weight is little, and is heat insulation good, high temperature resistant, but it is numerous and diverse to construct, and human body skin is had stimulation.(4) expanded perlite product: unit weight is little, and is nonpoisonous and tasteless, inexpensive, but effect of heat insulation is poor, loosely organized easy heat radiation.(5) heat insulation and waterproofing powder: major ingredient is talcum powder and lime carbonate, waterproof, freeze proof, sound isolating and flame-retardant, but range of application only limits to the plane, and construction inconvenience contacts for a long time with water, and heat insulation effect is poor.(6) to disclose a kind of lagging material and used member (publication number CN105676A, the 7th volume No. 49) this kind material of this kind lagging material be major ingredient with cement, synthetic resin emulsion, organic or inorganic microballoon to Chinese patent 91103347.5.Chinese patent 88104400.8 regenerating, heat insulation, and waterproof coating materials (No. 18, the 5th volume) are to add to be coated with on original asphalt roofing, make the roof insulation waterproof.Chinese patent 88107600.7 neither be raw material with the sepiolite as the lagging material (No. 21, the 5th volume) of thermal insulation of roof and sealing ply.Chinese patent 86101280 long-acting building waterproof (the 3rd volume No. 6) mainly are made up of polymer composite, are characterized in that waterproof, erosion resistance are good, and the temperature range that conforms is wide.
In the prior art, also do not find to produce the report of heat retaining and insulated waterproof material with sepiolite.Product item of the present invention is classified " eight or five " Program for Tackling Key Problems as after the examination of the Hunan Province State Scientific and Technological Commission.
The purpose of this invention is to provide heat insulation and waterproofing and leakage-stopping product of a kind of novel heat insulation and uses thereof, use this product easy construction, cost reduces, and is respond well.
The present invention is with clay mineral sepiolite [Mg

2O] be main raw material, be aided with tackiness agent, asbestos wool powder or particulate perlite and be mixed and processed.Product divides insulation heat-insulation paste A and two groups of water-proof stop leakage paste B, and heat insulating cream A is by the sepiolite of 70～85 parts of weight, the metamorphic mineral of 10～15 parts of weights, the tackiness agent of 5～7 parts of weights and suitable quantity of water composition; Metamorphic mineral can be selected asbestos wool powder and particulate perlite for use.Water-proof stop leakage paste B is by the sepiolite of 80～90 parts of weights, 5～7 parts heavy tackiness agents, and the water of 5～10 parts of weights is formed, and tackiness agent can be with modified water glass or polyvinyl alcohol.
Product of the present invention is mainly used in the leak stopping of roofing and wall heat retaining and insulated waterproof, the heat insulating of various industrial pipelines and hot equipment.
Product of the present invention is a kind of nonpoisonous and tasteless white paste, is canescence closed circular works behind the heat insulating cream A drying and moulding, and thermal conductivity is 0.02～0.040W/M.K, dry unit weight 200～250Kg/M
3, linear shrinkage ratio 12～15%, cohesive strength is 6 * 10Pa, and safe handling temperature-40～800 ℃ is alkaline-resisting, sour, water-fast, and 30% acid (alkali) solution does not dissolve in 24 hours, does not ftracture, nondiscoloration, and plasticity-is strong, is suitable for wet construction.Easy construction, applied widely, roofing and wall, equipment pipe, refrigeration equipment, gate and valve, obform body, rotator etc. all are suitable for.
Water [proof leaks cream B can be compared with heat insulation and waterproofing powder according to customer need furnishing shades of colour, better effects if, and the life-span is long, and particularly construction is very convenient, is applicable to the surface of different shape.Be used for the normal and supporting use of sepiolite heat insulating cream of roof waterproof, spread upon on the thermal insulation layer.Can remove the roofing overhead plate, alleviate the roofing load, reduce construction costs.The test of B group cream impervious did not have infiltration, ultimate compression strength 3.8Kg/cm in 7 days for the 6.27KPa hydrostaticpressure
2, heat-resisting, freeze proof, resistance to deterioration is good.Two groups of paste of A, B not only can supporting uses but also can have been separated independent application, were more satisfactory heat insulation, the waterproofing and leakage-stopping products of light thermal-insulating at present.
Product preparation of the present invention, purposes and constructional method
The preparation of heat insulating cream A: selected sepiolite powder, require fineness, purity to meet the requirements, take by weighing the sepiolite powder of 85 parts of weights, add the asbestos wool of 5～8 parts of weights, the particulate perlite of 5～8 parts of weights, the water of 5～10 parts of weights, the tackiness agent of 5～7 parts of weights mixes.Tackiness agent adopts modified water glass or polyvinyl alcohol.
The preparation of water-proof stop leakage paste B: the sepiolite powder specification of quality is the same, adds modified water glass, both weight ratios 80～90: 5～6, and the water that adds 5～10 parts of weights again mixes.
End-use of the present invention is wide, social and economic benefits and good.Now be mainly used in:
1. roofing and wall heat insulating, waterproofing and leakage-stopping.
Constructional method is: do the thick cement mortar protective layer of 15～20mm thereon after smearing the thick sepiolite water-proof stop leakage paste → drying of 2mm thereon after cleaning roofing (roof boarding jointing) → smear 7～10mm thick (dry back) sepiolite heat insulating cream → drying.As above people's roofing is done the thick concrete cover of 30～40mm.Palpus parting when doing protective layer, dried back seals in stitching, maintenance.
2. industrial pipeline heat insulating (comprising obform body, rotator etc.)
Constructional method is: dirt rust in pipeline top layer is cleaned clean → brush skim A group paste (to be dried) → calculating insulation layer thickness (the thick A group of general every 10mm paste can be lowered the temperature 70～100 ℃) → layering with the iron brush and smear A and organize cream (not exerting pressure).Yard piping needs wrapping and is coated with water-proof stop leakage paste to form waterproof layer for anti-rainwater washes away and the foreign matter collision.
Product of the present invention is used for roofing, can replace traditional perlite fully, Roofing slab is made the roof heat insulation thermofin.Waterproof can replace materials such as malthoid, ointment, water-proofing powder.More traditional material construction can be saved cost more than 30%, and accelerating construction progress, and is harmless, is used for industrial pipeline, can replace perlite, rock wool, asbestos wool fully, super glass wool, and good energy-conserving effect, cost is low.
In addition, this invention product also can be used for the heat insulating of refrigeration equipment (as refrigerator, freezer).
