Description
Technical field
The present invention relates to a kind of base treatment agent is and in particular to a kind of moisture substrate base treatment agent.
Background technology
At present with the matching used base treatment agent of coiled material, mainly with solvent type blackbase inorganic agent and soluble asphalt
Base treatment agent, but these base treatment agents all can not normally use in moisture substrate.For example, prior art
CN201110097240.4 discloses a kind of primer of substrate for solvent-type self adhesive waterproof, will constitute the former of base treatment agent
Material mix and blend heating finished product, described raw material components and mass percent are as follows：Colophonium 30%～33%, solvent 30%
～35%, softening oil 4%～6%, the first component asphalt modifier 4%～6%, the second component asphalt modifier 8%～12%,
Filler 16%～20%.This invention solves the poisonous of general oiliness blackbase inorganic agent has pollution, peel strength low, resistance to
The problems such as hot and poor performance at low temperatures, have the advantages that peel strength is high, high temperature performance is good, environment-protecting asepsis.But this invention
Surface drying time be 1 hour it is clear that not ideal enough it is impossible to normally use in moisture substrate well.CN201210202646.9 is public
Open a kind of polymer modified asphalt waterproof roll aqueouss base treatment agent, described base treatment agent is mainly by Colophonium, breast
Agent, water, antifreeze, stabilizer, drier composition, many kinds of substance is mixed to prepare product handling system agent, its component and weight portion
Number is as follows：Colophonium 40-60 part, emulsifying agent 0.1-2.5 part, water 30-50 part, antifreeze 10-30 part, stabilizer 0.1-1.5 part, urge
Dry agent 0.1-0.6 part, this invention product is tasteless, nontoxic, environmental protection, to workmen's no health hazard, and can be at subzero 20 DEG C
Transport, storage are not freezed；Rate of drying is fast, and, bonding force good with coiled material and basic unit's compatibility is strong；The temperature of construction film forming is less than existing
15 DEG C of the base treatment agent using is had on market.But this invention surface drying time is 30 minutes, is still not reaching to perfect condition.
Therefore, it is badly in need of exploration exploitation one kind to use in moisture substrate, energy rapid draing, and have more preferably with cement concrete, coiled material
Caking property base treatment agent.
Content of the invention
The technical problem to be solved is to provide a kind of rapid draing of energy, and has more with cement concrete, coiled material
The moisture substrate base treatment agent of good caking property.
The present invention will solve its technical problem and employed technical scheme comprise that：
A kind of moisture substrate base treatment agent of the present invention, is made up of component A and B component, wherein, A, B component include with
The raw material of lower percentage by weight is made：

Further, described emulsified asphalt is made up of the raw material of following percentage by weight：Colophonium 50%～65%, anion breast
Agent 3%～10%, nonionic emulsifier 3%～10%, stabilizer 1%～5%, remaining is water.
Further, described emulsified asphalt is made up of the raw material of following percentage by weight：Colophonium 60%～65%, anion breast
Agent 4%～6%, nonionic emulsifier 3%～6%, stabilizer 1%～3%, remaining is water.
It has been investigated that, because single emulsifier has fixing HLB value it is impossible to meet required for complicated asphalt emulsification
HLB scope.So single emulsifier cannot meet the requirement to emulsified asphalt for the moisture substrate base treatment agent.The present invention especially selects
Select anionic property and two kinds of emulsifying agents of nonionic, compounded in different ratios, formed compound emulsifying agent, be conducive to disappearing
It is also easy to produce the low problem of cloud point except independent with non-ionic emulsifier it is also possible to avoid individually using anionic emulsifier, Colophonium
The thick problem of granule.Therefore, the emulsifying agent that anionic property and two kinds of emulsifying agents of nonionic compound, can reduce both profits
Between relative density difference and viscosity difference, strengthen bitumen particle potential it is easy to formed electric double layer, increase granule between
Mutually exclusive power, hinder bitumen particle polymerization tendency.
Further, described Colophonium is selected from the mixture of one or more of bitumen, asphalt, coal tar pitch；Institute
State anion emulsifier and be selected from enuatrol, sodium abietate, sodium laurate, sodium naphthenate, sodium stearate, DBSA
