Description
Technical field
The present invention relates to a kind of base treatment agent, be specifically related to a kind of moisture substrate base treatment agent.
Background technology
At present and the matching used base treatment agent of coiled material, mainly with solvent type black base treatment agent and soluble asphalt basic unit treatment agent, but these base treatment agents all can not normally use at moisture substrate.Such as, prior art CN201110097240.4 discloses a kind of primer of substrate for solvent-type self adhesive waterproof, the obtained finished product of raw material mix and blend heating of base treatment agent will be formed, described feed composition and mass percent as follows: pitch 30% ~ 33%, solvent 30% ~ 35%, softening oil 4% ~ 6%, the first component asphalt modifier 4% ~ 6%, second component asphalt modifier 8% ~ 12%, weighting agent 16% ~ 20%.What this invention solved general oiliness black base treatment agent poisonously has that pollution, stripping strength are low, the problem such as thermotolerance and poor performance at low temperatures, has the advantages such as stripping strength is high, high temperature performance good, environment-protecting asepsis.But this invention surface drying time is 1 hour, obviously not ideal enough, can not well normally use at moisture substrate.CN201210202646.9 discloses a kind of polymer modified asphalt waterproof roll use base treatment agent, described base treatment agent is primarily of pitch, emulsifying agent, water, antifreezing agent, stablizer, siccative forms, the obtained product handling system agent of many kinds of substance mixing, its component and parts by weight as follows: pitch 40-60 part, emulsifying agent 0.1-2.5 part, water 30-50 part, antifreezing agent 10-30 part, stablizer 0.1-1.5 part, siccative 0.1-0.6 part, this invention product is tasteless, nontoxic, environmental protection, to workmen without Health hazard, and can in subzero 20 DEG C of transports, storage is not freezed, rate of drying is fast, with coiled material with basic unit's consistency is good, bonding force is strong, the temperature of construction film forming is lower than the base treatment agent that existing market uses 15 DEG C.But this invention surface drying time is 30 minutes, does not still reach perfect condition.Therefore, being badly in need of exploring exploitation one can use at moisture substrate, energy rapid drying, and has better close-burning base treatment agent with cement concrete, coiled material.
Summary of the invention
Technical problem to be solved by this invention is, provides the rapid drying of a kind of energy, and has better close-burning moisture substrate base treatment agent with cement concrete, coiled material.
The technical scheme that the present invention will solve the employing of its technical problem is:
A kind of moisture substrate base treatment agent of the present invention, is made up of component A and B component, and wherein, the raw material that A, B component comprise following weight percent is made:
Component A: emulsified bitumen 50% ~ 80%,
Modified emulsion 10% ~ 40%,
Auxiliary agent 1% ~ 5%;
Further, the raw material that described A, B component comprise following weight percent is made:
Component A: emulsified bitumen 55% ~ 65%,

Further, described emulsified bitumen is made up of the raw material of following weight percent: pitch 50% ~ 65%, anionic emulsifier 3% ~ 10%, nonionic emulsifying agent 3% ~ 10%, stablizer 1% ~ 5%, and all the other are water.
Further, described emulsified bitumen is made up of the raw material of following weight percent: pitch 60% ~ 65%, anionic emulsifier 4% ~ 6%, nonionic emulsifying agent 3% ~ 6%, stablizer 1% ~ 3%, and all the other are water.
Find after deliberation, because single emulsifier has fixing HLB value, HLB scope required for complicated asphalt emulsification can not be met.So single emulsifier cannot meet the requirement of moisture substrate base treatment agent to emulsified bitumen.The present invention have selected anionic property and nonionic two kinds of emulsifying agents especially, carry out composite in different ratios, form compound emulsifying agent, be conducive to eliminating and easily produce the low problem of cloud point with non-ionic emulsifier separately, also can avoid using anionic emulsifier separately, the problem that pitch particle is thick.Therefore, anionic property and the composite emulsifying agent of nonionic two kinds of emulsifying agents, 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.
Further, described pitch is selected from one or more the mixture in rock asphalt, petroleum pitch, coal-tar pitch; 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 and polyoxyethylene phosphate; 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 and polyoxyethylene nonylphenol ether; Described stablizer is selected from one or more the mixture in polyvinyl alcohol, Mierocrystalline cellulose and inner complex.
Further, described petroleum pitch is oil heavy traffic asphaltum, and its penetration degree is 60 ~ 100 in units of 0.1mm.
Further, described modified emulsion is composited by polychloroprene latex, 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, chlorosulfonated polyethylene latex etc.
Further, described auxiliary agent is selected from one or more the mixture in polyvinyl alcohol, Mierocrystalline cellulose and inner complex.
Further, described cement is selected from one or more the mixture in white cement and ash concrete; Described grating sand is selected from 20 ~ 40 orders, 40 ~ 80 orders, 80 ~ 120 orders or 200 order quartz sands; Described filler is selected from one or more the mixture in calcium carbonate, talcum powder and wollastonite powder; Described auxiliary agent is selected from one or more the mixture in water reducer, stablizer and thickening material.
The preparation method of the moisture substrate base treatment agent of the present invention, comprises the following steps:
(1) component A preparation method: emulsified bitumen, modified emulsion, filler are joined a mixing bowl, moderate-speed mixer 20 minutes, filters after static 1 hour, packaging.
