The waterproof mortar of the asphalt comprises a component A and a component B, wherein the component A is emulsified asphalt; the component B is prepared from the following raw materials in parts by weight: 50-70 parts of cement, 10-30 parts of packing and 1-5 parts of an adjuvant. The waterproof mortar of the asphalt has excellent adhesiveness and self-healing property, so that the protected object is completely sealed without a gap; and the waterproof mortar can resist corrosion of low-concentration inorganic acids, alkalis and salts, ultraviolet ray and biodegradation, has excellent anti-stripping ability, good softness, and excellent characteristics of being non-toxic, tasteless, free of pollution and the like, and is excellent in application property and low in price. The waterproof mortar of the asphalt can be used as a coating waterproof layer, and is applied to basements of buildings, road and bridge decks, tunnels and the like.
Description
Technical field
The present invention relates to a kind of waterproof mortar and preparation method thereof, be specifically related to a kind of asphalt waterproofing mortar and preparation method thereof.
Background technology
Pitch is by the molecular mixture of multiple high score of complex chemical composition, has unique rheological property, because of its good cohesiveness, resistance to deterioration and waterproof ability, is widely used in waterproof and sealing material, road repair etc. for a long time.As a kind of traditional water-proof material, there are the advantages such as material source is extensive, cheap, the mineral acid of ability lower concentration, alkali and salt corrosion, make pitch still have huge application market so far.
At present, cement plaster exists not water-fast, needs maintenance, and easily occurs problems of crack.And joined by pitch in mortar and can increase splitting resistance, and improve the water tolerance of product.Current, the use-pattern of pitch mainly contains heated bitumen, fluxed asphalt, emulsified bitumen.Compared with heated bitumen, fluxed asphalt, emulsified bitumen save energy 40%-50%, improves execution conditions, reduces more than construction costs 20%-30%, and the pitch overaging caused when effectively can reduce heat, and make a large amount of volatilizations of carcinogens benzo pyrrole.Particularly, along with the progressively raising of Infrastructure waterproof requirement, and the developing rapidly of road slurry seal and micro-surface area, the very big development that must facilitate emulsified bitumen.But, while emulsified bitumen has many merits, its stability in storage, with the mixing property of gathering materials, pave after condensation performance index govern the development of emulsified bitumen, production, transport and application always.Research finds, single emulsifier cannot meet the requirement of asphalt waterproofing mortar to emulsified bitumen, because single emulsifier has fixing HLB value, it can not meet HLB scope required for complicated asphalt emulsification.
Summary of the invention
Technical problem to be solved by this invention is, provides the asphalt waterproofing mortar of a kind of good water-repellancy and crack resistence, ensures the waterproof quality of product, improves the application property of product.
The technical scheme that the present invention solves the employing of its technical problem is:
A kind of asphalt waterproofing mortar, be made up of component A and B component, described component A is emulsified bitumen; Described B component is made up of the raw material of following parts by weight: cement 50-70 part, filler 10-30 part, auxiliary agent 1-5 part.
Further, described emulsified bitumen is made up of the raw material of following parts by weight: pitch 50-65 part; Anionic emulsifier 3-10 part, nonionic emulsifying agent 3-10 part, stablizer 1-5 part, all the other are water.
Further, described emulsified bitumen is made up of the raw material of following parts by weight: pitch 60-63 part; Anionic emulsifier 4-6 part; Nonionic emulsifying agent 4-6 part; Stablizer 2-3 part, all the other are water.
Further, described pitch is selected from one or more mixtures in rock asphalt, petroleum pitch, coal-tar pitch.
Further, described pitch is oil heavy traffic asphaltum, and its penetration degree is 60-100 (1/10mm).
Further, described anionic emulsifier is selected from one or more the mixture in sodium oleate, sodium abietate, sodium laurate, sodium napthionate, sodium stearate, Sodium dodecylbenzene sulfonate, two ten alkyl phenyl ether sodium disulfonates, sodium dibutyl naphthalene sulfonate, sodium lignosulfonate, sodium lauryl sulphate, N-methyl oleoyl methylamine ethyl sulfonic acid sodium, N-methyltaurine sodium, polyoxyethylene phosphate.

Adopt above-mentioned two kinds of anionic properties and nonionic asphalt emulsifier to carry out compound, be conducive to eliminating alone non-ionic emulsifier and easily produce the low problem of cloud point, also can avoid alone anionic emulsifier, the problem that pitch particle is thick.Use above-mentioned composite emulsifier, profit relative density difference between the two and the difference of viscosity can be reduced, 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.
Further, described stablizer is selected from one or more mixtures in polyvinyl alcohol, Mierocrystalline cellulose, inner complex.
Further, Mierocrystalline cellulose is selected from Natvosol.
Further, inner complex is selected from tartrate, tripoly phosphate sodium STPP, in ethylenediamine tetraacetic acid (EDTA) any one.
