Description
Technical field
The present invention relates to a kind of emulsified bitumen based waterproof mortar, belong to waterproof chemistry Material Field.
Background technology
Owing to there is the various features such as cheap, easy to use, current sand-cement slurry is one of water-proof material the most frequently used in house decoration between toilet, kitchen etc., but sand-cement slurry exists not water-fast, need maintenance, easily there is problems of crack, especially sand-cement slurry is poor to acid-basicity tolerance, and life-time service easily occurs that corrosion makes it drop or loses water-repellancy.
In order to overcome the problems referred to above, this area was once attempted polymer emulsion, as mixed with sand-cement slurry in SBR emulsion, acrylic ester emulsion etc. with the performance of reinforced cement mortar, but polymer emulsion high cost, and popularization and use are subject to construction and decoration restraint of trade.For this reason, this area also attempts exploring utilizing pitch to improve the performance of sand-cement slurry in recent years, but finds that the consistency of common emulsified bituminous materials and cement is poor in long-term construction, causes the waterproof quality of product, application property is affected.
Summary of the invention
For the defect of prior art, the invention discloses a kind of emulsified bitumen waterproof mortar, coordinate with specific cement slurry by adopting the emulsified bitumen of special development, consistency is better, waterproof quality and application property good, for concrete wall surface, there is excellent binding property, self-healing, protected object is sealed completely, seamless; Acid-alkali-corrosive-resisting; Uvioresistant and biological degradation; Outstanding antistripping ability; The excellent specific property such as nontoxic, tasteless, pollution-free, and low price.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of emulsified bitumen waterproof mortar, be made up of component A and B component, wherein component A comprises emulsified bitumen, is made up of the component of following weight content: pitch 50%-65%; Cationic emulsifier 3%-10%, nonionic emulsifying agent 3%-10%, stablizer 1%-5%, all the other are water; B component comprises cement, filler, auxiliary agent, and the content of each component is cement 40%-75%, filler 20%-55%, auxiliary agent 1%-5%.
Preferably, the weight percent of each component composition of emulsified bitumen is: pitch 58%-63%; Cationic emulsifier 3%-6%; Nonionic emulsifying agent 3%-6%; Stablizer 1%-3%, all the other are water.
Preferably, each composition weight percentage composition of B component is cement 45%-55%, filler 43%-53%, auxiliary agent 2%-3%.
In the present invention, described pitch selects one or more the mixture in white rock asphalt, petroleum pitch, coal-tar pitch, preferred heavy traffic paving asphalt, more preferably employing penetration degree is the heavy traffic paving asphalt of 60-100 (1/10mm).
In the present invention, in order to meet the requirement of asphalt waterproofing mortar to emulsified bitumen, HLB scope required for coupling asphalt emulsification, adopts cationic and the composite formation compound emulsifying agent of nonionic two kinds of emulsifying agents.Adopt compound emulsifying agent to be conducive to eliminating alone non-ionic emulsifier and easily produce the low problem of cloud point, also can avoid alone cationic emulsifier, the problem that pitch particle is thick.Use composite emulsifier can reduce profit relative density difference between the two and the difference of viscosity, strengthen the electromotive force of bitumen particle, be easy to form electrostatic double layer, increase the mutual repulsive force between particle, hinder the polymerization tendency of bitumen particle.
Wherein, described cationic emulsifier is selected from one or more the mixture in lauryl amine, tetradecylamine, hexadecylamine, docosyl amine, coconut oleyl amine, tallow amine, hydrogenated tallow amine, oleyl amine, soybean oleyl amine, 1-aminoethyl-2-heptadecyl imidazole quinoline-2 hydrochloride, lignin amine, dodecyl benzyl dimethyl ammonium chloride, dodecyldimethylamine ammonium chloride, cetalkonium chloride; Described nonionic emulsifying agent is selected from one or more the mixture in laurostearic acid single ethanol amide, lauryl diethanol amide, Coconut Fatty Acid Monoethanolamide, lauric acid amide of ethanol, polyoxyethylene sorbitan monolaurate, octadecanoic acid ester of polyethylene glycol, polyoxyethylene nonylphenol ether.
In the present invention, described stablizer is selected from one or more the mixture in inorganic salt, mineral acid, organic acid, tackifier.
Wherein, inorganic salt can be vitriol, nitrate, hydrochloride etc.; Mineral acid or organic acid can be lipid acid, acetic acid, hydrochloric acid, tartrate etc.; Tackifier can be polyvinyl alcohol, Mierocrystalline cellulose, inner complex etc.
In the present invention, described cement is selected from white cement and/or ash concrete; Described filler is selected from one or more the mixture in calcium carbonate, talcum powder, wollastonite powder, quartz sand; Described auxiliary agent is selected from one or more the mixture in water reducer, stablizer, thickening material.
Above-mentioned water reducer, thickening material are all this area customary adjuvant, and such as water reducer can be poly carboxylic acid series water reducer or naphthalene water reducer; Thickening material can be ether of cellulose etc.
Accordingly, the invention also discloses the preparation method of described emulsified bitumen waterproof mortar, comprise the steps:
The preparation method of component A:
1) by pitch dewatering, 130 DEG C-160 DEG C are then heated to;
2) water is heated to 45 DEG C-65 DEG C;
3) cationic emulsifier and nonionic emulsifying agent, stablizer are joined step 2) hot water in, stir, make aqueous emulsion, control temperature is 45 DEG C-65 DEG C;
4) in step 3) aqueous emulsion in pour step 1 into immediately) heated bitumen, namely obtain emulsified bitumen after stirring;
The preparation method of B component: cement, filler and auxiliary agent are stirred.
In above-mentioned preparation method, pitch dewatering can be adopted in any way, preferably adopts pitch at 110 DEG C-130 DEG C dehydration 1-2 hour.
In above-mentioned preparation method, step 4) usually adopt mulser to carry out, first aqueous emulsion is poured in mulser, pours step 1 into immediately) heated bitumen, namely obtain emulsified bitumen after stirring.
