Emulsified bitumen in this system is to develop for this system specially, compares with common emulsified bitumen, and this emulsified bitumen has and modified latex, the better consistency of sand-cement slurry, guarantees the waterproof quality of product, improves the application property of product.
This product has been widely used in waterproof and protection against corrosion fields such as building construction, municipal traffic, petrochemical industry electric power, environment protection, oceanographic engineering, hydro project.This product and technology have embodied the development of international waterproof and corrosion-resistant field initiative.
Technical scheme involved in the present invention:
The asphalt polymer cement waterproof paint is made up of A component and B component, and the A component comprises emulsified bitumen, modified latex, and the B component comprises cement, filler, auxiliary agent, the content of various raw materials in A, the B component wherein, and (as follows) meter is as follows by weight percentage:
A component: emulsified bitumen: 20%-50%
Modified latex: 30%-50%
Water: 10-30%
The B component:
Cement: 40%-60%
Filler: 20%-40%
Auxiliary agent: 1%-5%.
Emulsified bitumen of the present invention is formed: pitch 50%-65%; Preferred 58%-63%,
Cationic emulsifier 3%-10%, preferred 3%-6%;
Nonionic emulsifying agent 3%-10%, preferred 3%-6%;
Stablizer 1%-5%, preferred 1%-3%;
All the other are water.
Pitch wherein can be rock asphalt, petroleum pitch, coal-tar pitch and composition thereof, oil heavy traffic asphaltum preferably, and its penetration degree is 60-100(1/10mm).
The application finds that after deliberation single emulsifying agent can't satisfy the asphalt polymer cement waterproof paint to the requirement of emulsified bitumen, because single emulsifying agent has fixing HLB value, it can not satisfy the complicated required HLB scope of asphalt emulsification.Therefore the present invention has selected cationic and two kinds of emulsifying agents of nonionic especially, carries out compositely in different ratios, forms compound emulsifying agent.In concrete asphalt emulsifier was selected, the used cationic asphalt emulsifier of the present invention had been selected one or more in lauryl amine, tetradecylamine, hexadecylamine, docosyl amine, coconut oleyl amine, tallow amine, hydrogenated tallow amine, oleyl amine, soybean oleyl amine, 1-aminoethyl-2-heptadecyl tetrahydroglyoxaline-2 hydrochloride, lignin amine, dodecyl benzyl dimethyl ammonium chloride, tetradecyl alkyl dimethyl ammonium chloride, the cetalkonium chloride.The present invention is in laurostearic acid single ethanol amide, lauryl diethanol amide, coconut oil single ethanol amide, lauric acid amide of ethanol, polyoxyethylene sorbitan monolaurate, octadecanoic acid ester of polyethylene glycol, the polyoxyethylene nonylphenol ether one or more to the nonionic asphalt emulsifier.It is compound to adopt mentioned emulsifier to carry out, and is conducive to eliminate list and easily produces the low problem of cloud point with non-ionic emulsifier, also can avoid single use cationic emulsifier, the problem that pitch particle is thick.Use above-mentioned composite emulsifier, can dwindle profit between the two the relative density difference and the difference of viscosity, strengthen the electromotive force of pitch particulate, be easy to form electrostatic double layer, increase the mutual repulsive force between the particle, hinder the polymerization tendency of pitch particulate.
The used stablizer of the present invention can be inorganic salt, as vitriol, nitrate, hydrochloride etc.; Also can be mineral acid or organic acid, as lipid acid, acetic acid, hydrochloric acid, tartrate etc.; Can be polyvinyl alcohol, Mierocrystalline cellulose, inner complex etc.; Also can be above-mentioned two kinds or three kinds and mix use.
Modified latex of the present invention is selected from: one or more in cationic chloroprene latex, positively charged ion styrene-butadiene latex, pure acrylic acid latex, styrene-acrylic latex, natural rubber latex, nitrile rubber, isobutylene-isoprene latex, polyisoprene latex, ethene-vinyl acetate latex, Ethylene Propylene Terpolymer latex, binary ethylene propylene rubber latex, chlorinated butyl latex, the chlorosulfonated polyethylene latex etc.
Cement of the present invention is selected from: one or more in white cement, the ash concrete etc.
Filler of the present invention is selected from: calcium carbonate, talcum powder, wollastonite powder, quartz sand etc.
Auxiliary agent of the present invention is formed: one or more in water reducer, stablizer, the thickening material etc.
Product preparation process flow process of the present invention is as follows:
Emulsified bitumen preparation technology flow process in the product of the present invention is as follows:
(1) with 50%-65% pitch earlier 110 ℃-130 ℃ dehydrations 1 hour-2 hours, mild heat to 130 is ℃-160 ℃ then, the metering back is standby;
(2) tap water is heated to 45 ℃-65 ℃, the metering back is standby;
(3) emulsifying agent, stablizer are joined in the standby hot water, stir, make aqueous emulsion, the control temperature is 45 ℃-65 ℃, and standby, emulsifying agent refers to that cationic emulsifier and nonionic emulsifying agent are composited;
(4) open the mulser system, the aqueous emulsion that meets temperature requirement that step (3) makes is poured in the emulsifying agent, pour the heated bitumen that meets temperature requirement that step (1) makes immediately into, the satisfactory emulsified bitumen preparation in the back that stirs is finished.
A component preparation method:
20%-50% emulsified bitumen, 30%-50% modified latex that step (4) is made join the stirring of a mixing bowl high speed, stir 20 minutes, and static half an hour, hour after-filtration discharging was packed.
B component technology:
40%-60% cement, 20%-40% filler and 1%-5% auxiliary agent are joined a mixing bowl high speed stir, stir discharging packing after 30 minutes.
Asphalt polymer cement waterproof paint of the present invention, cheap, application property is excellent, mineral acid, alkali and the salt corrosion of good waterproof performance, ability lower concentration, good flexibility is arranged.
The asphalt polymer cement waterproof paint can be separately as film waterproof material usefulness, and it is medium to be used for kitchen and toilet, vault and bridge deck water-proof antiseptic project.
