Abstract
Building water-proof powder and production method thereof.This water-proofing powder is to be raw material with industrial sintering waste residue, calcium hydroxide and lipid acid ammonium, the formation of its basic granules is to be core with industrial sintering waste residue, its external parcel one deck has the fatty acid calcium of hydrophobicity performance, its production method is industrial sintering waste residue to be mixed the back add the lipid acid ammonium with calcium hydroxide, stir, drying just obtains water-proofing powder.
Product of the present invention has added a large amount of waste residues, so raw materials cost is lower.Production method of the present invention does not need to make slurry, has therefore reduced production processes such as intensification, dehydration, saves time, and shortens the production cycle, compares with wet production, and saving equipment, place are invested more than 90%.The water-proofing powder cost is reduced greatly.
Description
The invention belongs to powdery waterproof material for building and production method thereof.
At present, the water-proof material that uses in the construction work is of a great variety, and waterproofing unction, coiled material, sheet material etc. are arranged.Except that the preparation complexity, the ratio of performance to price is also not ideal.In recent years, powdery waterproof material comes out.Chinese patent CN87101009.A discloses a kind of hydrophobe and production method thereof.This hydrophobe has ageing-resistant, and is not perishable, characteristics such as good water-proof effect.It is a raw material with calcium oxide, lipid acid and ammonium water, makes through technologies such as saponification, digestion, dehydration, oven dry.A spot of calcium hydroxide and fatty acid response generate fatty acid calcium, and fatty acid calcium is surrounded a large amount of calcium hydroxide particles that does not react, and having formed with the calcium hydroxide particle is nuclear, and appearance has the new particle of hydrophobic effect.What really play waterproof action is the fatty acid calcium of particle outside surface, and a large amount of calcium hydroxide only plays carrier function.Like this, cause the waste of calcium hydroxide, the raw materials cost of hydrophobe is increased.In addition, the hydrophobe production method that this patent provides is a wet method, and its digestion, dehydration, drying course need consume the more energy, needs certain device and large-area place simultaneously, thereby production cost is increased.
The purpose of this invention is to provide a kind of novel building water-proof powder, this water-proofing powder is with the carrier of the extremely low raw material of price as fatty acid calcium, thereby it is lower to produce cost, low-cost water-proofing powder.
Water-proofing powder of the present invention is by being core with industrial sintering waste residue particulate, and appearance is formed by the basic granules that fatty acid calcium surrounded.The basic granules of water-proofing powder of the present invention is to be carrier with industrial sintering waste residue particulate, because industrial sintering waste residue fine particle surface irregularity, hole is more, thereby can adsorb a large amount of calcium hydroxide, particulate is wrapped up by calcium hydroxide, these calcium hydroxides and lipid acid ammonium react, and have formed the fatty acid calcium layer on the particulate surface, and the long carbochain of fatty acid calcium has the hydrophobic effect.By the pulvis that such basic granules is formed, has tangible waterproof effect.
Production method of the present invention is as follows: the calcium hydroxide (white lime) more than 80% mixes with industrial sintering waste residue more than fineness 80 orders and active constituent content, adds the lipid acid ammonium solution for preparing then, and fully stirs.Make the reaction of calcium hydroxide and lipid acid ammonium, generate fatty acid calcium.Again product is in the pasty state dried, promptly get the powdered water-proofing powder.The formulation weight of water-proofing powder of the present invention is than being the lipid acid ammonium: calcium hydroxide: industrial sintering waste residue=1: 2～40: 2～40.The lipid acid ammonium is by weight 1: 0 by lipid acid and rare ammonium water.1～0。9 mixed forms.
Water-proofing powder provided by the invention, owing to having adopted the industrial sintering waste residue that the source is abundant, cost is extremely honest and clean (mainly being the flyash, agglomerating pyrite slag, ashes etc. of power plant) in a large number as raw material, make the products material cost reduce, in addition, owing to adopt new technology, reduce heating, digestion, cooling, dewatering process process, shortened the production cycle.Compare with wet production, the investment of having saved equipment and factory building, place has reduced production cost more than 90%.Therefore, water-proofing powder provided by the invention is than the like product 15-20% that reduces cost.The structure of product of the present invention forms except that adsorption, and the contained oxide compound (silicon oxide magnesium oxide, ferric oxide etc.) of industrial sintering waste residue also reacts with calcium hydroxide, so, product structure of the present invention is firm, moisture-sensitive is not wet, the influence of ambient conditionss such as temperature, stable performance.Product of the present invention also has advantages such as body is light, good permeability except that having favorable waterproof property.
Embodiment:
Example 1, by lipid acid: water: the ammonium water weight ratio is that to prepare lipid acid ammonium solution at 1: 25: 05 standby.With fineness is that 1 kilogram of sintering pyrite slag more than 80 orders and 2 kilograms calcium hydroxide mix, and the lipid acid ammonium solution that adds 25 kilograms then fully stirs, stop to stir after in the pasty state, dries, and makes water-proofing powder.
Example 2, be that 15 kilograms of ashes and 20 kilograms of calcium hydroxides more than 100 orders mix with fineness, the lipid acid ammonium solution that the ratio preparation that provides in example 1 is provided then fully stirs for 35 kilograms, stops to stir after in the pasty state, dries, and makes water-proofing powder.
Example 3, be that 200 kilograms of fine coal and 200 kilograms of calcium hydroxides more than 100 orders mix with fineness, the lipid acid ammonium solution that the ratio preparation that provides in example 1 is provided then fully stirs for 400 kilograms, stops to stir after in the pasty state and dries, and makes water-proofing powder.
Claims (6)
