At least there are the following problems in base treatment agent technology: 1) cation type is mostly used, it is poor with the cohesive force of alkaline base.
For example, prior art CN201210202646.9, CN201610193303.9 is using cationic emulsified bitumen as base treatment
Agent, and cationic emulsified bitumen pH value easily occurs to chemically react and generate precipitating with alkaline base in acidity, so as to cause base
Inorganic agent is difficult to bond with alkaline base.2) the strong anion base treatment agent of cohesive force, big multicomponent is simple, not yet using height
Copolymer emulsion is modified, causes weatherability poor, such as prior art CN201110178280.1, CN201310527653.0, resistance to
Time property is mainly provided by the matrix asphalt after forming a film, and the softening point of matrix pitch be generally below 50 DEG C and black brittleness compared with
Greatly, therefore the high heat resistance and low temperature cracking resistance of prepared anion base treatment agent；Or even if using polymer emulsion
The polymer emulsion for being modified, but choosing is rubber latex, and price is higher, additive types are various, production equipment is complicated, example
Such as CN201610273495.4, CN201610274490.3, but both technologies belong to asphalt waterproofing material according to purpose classification
Class, it may be assumed that product is generally used alone as waterproof layer, general to require the film forming thickness after constructing seldom with the compound construction of asphalt felt
At least in 1.5mm, it is necessary to which thickness applies construction.And two kinds of technical products are bi-component, need to be solidified using curing agent, are needed
Want special spraying equipment, complex process.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of alkaline base treatment agent for asphalt water-proof coiled material and
Preparation method, can solve anion base treatment agent type of the existing technology is few, specificity is poor, weatherability is poor, production
The problem of complex process.
The technical solution used to solve the technical problems of the present invention is that at a kind of alkaline base for asphalt water-proof coiled material
Agent is managed, is prepared from the following raw materials in parts by weight, 32~46 parts by weight of pitch, are gathered at 0.2~1.0 parts by weight of anion emulsifier

~50 parts by weight.
Further, the pitch is No. 70 or/and No. 90 bi tumenf orr oads.
Further, the anion emulsifier is stearic acid sodium class, oleic acid soaps, sodium alkyl sulfonate class, lignin sulfonic acid
The mixture of one or more of salt and alkyl sulfate salt.
Further, the PTFE emulsion is solid content >=60%, pH value 9~11,0.3 μm of average grain diameter or less.
Further, the defoaming agent is one of tributyl phosphate, organic silicon modified by polyether and polysiloxanes or two
Kind or more mixture；
Further, the stabilizer is polyvinyl alcohol, sodium carboxymethylcellulose, sodium hydroxyethlcellulose, hydroxy ethyl fiber
One of element, ethylenediamine tetra-acetic acid and sodium tripolyphosphate or two or more mixtures；
Further, the water is pollution-free technical grade water without heavy metal ion.
The present invention further solve its technical problem the technical solution adopted is that, a kind of alkalinity for asphalt water-proof coiled material
The preparation method of base treatment agent, comprising the following steps:
