Abstract
The invention discloses a kind of method of producing waterproof and heat-proof powder with light porous clay pit.The process of producing of product is: with these raw mineral materialss (wilkinite, diatomite, attapulgite, sepiolite) dispersed with stirring, transfer to alkalescence then, add organic carboxyl acid (salt) or organic alcohol again and carry out surface reaction and make this product.This product can be used for waterproof and heat-insulating, the sound insulation of flooring waterproof on roof, protection against the tide of vault etc.
Description
The invention belongs to the waterproof of using in the construction work, heat insulation (insulation) material field.
The water-proof material of present architectural use has waterproof roll, waterproof paint, water-resisting agent etc., but these materials some is easily aging, in case the crack appears in basic unit, can't remedy, leak thereby cause; Some material will be incorporated into to mix in other material and use.Heat preserving and insulating material such as foam heat-insulating plate, light porous mineral fiber tilesn etc. commonly used, these material moisture-sensitive, influence is used.In recent years, Chinese patent discloses 87101009A successively, 90102869.X, and the patent application of 90105847.5,91104534.1 water-proofing powder such as grade, these materials can remedy when basic crack automatically, have strengthened water-proof function.Some water-proofing powder also has certain heat insulating function, but the base material of these waterproof (heat insulation) powder is inorganic tight type raw material mostly, and unit weight is bigger, inner atresia, and the base material of hydrophobe on the market and heat insulation town pigment is respectively lime and lime carbonate.On material of construction was learned, light porous was the basic characteristics of general heat preserving and insulating material.Therefore, this has just determined that its heat-insulation and heat-preservation function of present water-proofing powder is very limited.
The objective of the invention is to, be main raw material with light porous clay pit, produces the powdered material that integrates the waterproof and heat-insulating function, to improve the deficiency of present water-proofing powder heat insulating function.
Principle of the present invention is: with light porous clay pit is basic raw material, and these raw material unit weights are light, and internal void is many, itself possesses heat insulation (insulation) function, and some is as the composition of insulating mold coating.But these mineral are hydrophilic, and the function that absorbs water is very strong.Under alkaline condition, make these raw mineral materialss and the organic carboxyl acid or the organic alcohol of high-carbon that contain longer carbochain carry out the complex surfaces absorption reaction, thereby make mineral surface hydrophobic.
The manufacture method of product of the present invention is: the clay pit raw material is added the water dispersed with stirring, add Ca(OH then)
2Liquid or lime or NaOH and Ca(OH)
2Mixed solution is sized mixing to alkalescence, restir size mixing (or heating size mixing) 10～40 minutes, slowly add the organic alcohol heating of organic carboxyl acid (salt) or high-carbon (or not heating) stirring again and carried out surface reaction in 20 minutes～1.5 hours, leave standstill then, dewater, dry, pulverize, pack.Clay mineral raw material: organic carboxyl acid (salt) (or the organic alcohol of high-carbon)=100: 5～20(weight ratio).
The main raw material that the present invention uses is light porous clay pits such as low-grade wilkinite (montmorillonite), diatomite, attapulgite, sepiolite, and it is very extensive to originate.At present, low-grade clay pit also fails to bring into play good effect in China, and the present invention provides large Application Areas for this class clay pit.Organic carboxyl acid (salt) is mixed fatty acid, naphthenic acid, oxidized petroleum wax (soap), or contains the grease factory dregs of fat or the refining of petroleum factory byproduct of these compositions, and price is also very cheap.The organic alcohol of high-carbon is carbon chain lengths greater than 12 alcohol mixture or single alcohol.
Product water-proof heat-insulating clay mineral powder of the present invention, can use equally with like product hydrophobe and heat insulation town pigment, promptly, at powder upper berth one deck interleaving paper, on paper, get final product again again coated with sand-cement slurry or pea gravel concreten at this powder of basic unit's upper berth 3～10mm thickness such as roof.
Advantage of the present invention:
1. the good test of water repelling property shows that this powder-product has stronger water resisting property, and, if force to make it wetting, still have hydrophobicity after the drying;
2. the heat-insulation and heat-preservation function records its thermal conductivity by force only for about 0.074W/M.K;
3. product appearance is loose, and there is micropore inside, and unit weight is light, and recording its unit weight is 320kg/m
3, only for lime be base material hydrophobe unit weight about 3/5 (hydrophobe unit weight is 540kg/m
3), do as one likes matter infers that this product has certain sound absorption function;
4. product is Powdered, has stress dispersive superperformance, not because of the crack appears in basic unit, distortion influences its waterproof and heat-insulating function;
5. raw material sources are extensive, price is low, production process is simple, pollution-free, be easy to industrialization.
Example one
Add wilkinite (being mixed with 20% diatomite) and water in agitation vat, dispersed with stirring adds Ca(OH)
2Solution transfers to alkalescence, stirs 40 minutes, adds the lipid acid ammonium solution more while stirring, continues to stir 30 minutes.Then, leave standstill dehydration, dry, pulverizing.Wilkinite: mixed fatty acid ammonium=100: the 8(weight ratio).
Example two
Sepiolite (containing 10% attapulgite) and water are gone into agitation vat, and dispersed with stirring adds Ca(OH)
2Transfer to strong basicity with the NaOH mixing solutions, be heated to 60 ℃, stirred 30 minutes, slowly add hybrid ring alkanoic acid liquid again, be incubated 60 ℃～70 ℃, continue to stir 1 hour.Leave standstill then, dewater, dry, pulverize.Sepiolite: hybrid ring alkanoic acid=100: the 10(weight ratio).
Example three
Low-grade sepiolite and water are gone into agitation vat, and dispersed with stirring adds lime and transfers PH to alkalescence, stirred 15 minutes, ore pulp is heated to 70 ℃～90 ℃, slowly add oxidized paraffin wax soap again, stirred 1.5 hours, then, leave standstill, dewater, dry, pulverize and promptly get powder-product.Low-grade sepiolite: oxidized paraffin wax soap=100: the 20(weight ratio).
Example four
Wilkinite and water are gone into agitation vat, and dispersed with stirring adds lime and transfers PH to alkalescence, and restir 20 minutes is heated to ore pulp more than 60 ℃, slowly adds the mixing high-carbon fatty alcohol (containing carbon number greater than 12) that dissolves, insulated and stirred 30 minutes.Then, leave standstill, dewater, dry, pulverize powder-product.Wilkinite: mix high-carbon fatty alcohol=100: the 10(weight ratio).
