Description
Technical field the present invention relates to a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, can be widely used in cement-concrete road bridge floor, composite pavement, tunnel and other building construction processes.
Background technology is current, and water-proof material mainly contains three classes: the first kind is solvent-borne type, and its main drawback is that cost is high, and poor stability is harmful, inflammable, contaminate environment; Equations of The Second Kind is aqueous emulsion high-molecular coating, and cost is high, not ideal enough; 3rd class is elastomeric modification pitch, and this series products low temperature flexibility is good, but during high temperature, performance is bad, and its technical feature is relatively unstable.And traditional coating needs heat construction, easy bubbling, easy embrittlement, normal seepage, maintenance is difficult, contaminate environment.
Summary of the invention in order to overcome above-mentioned shortcoming, the object of the present invention is to provide a kind of environmental protection, easy to operate, cohesiveness good, perviousness is strong, breakdown of emulsion is fast, cold construction, high, the good extensibility of work efficiency, low temperature flexibility, a kind of oil-in-water of raising service life of road surface, water-in-oil second-order reaction type water-proof cold adhesive.
In order to achieve the above object, the present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, its special character is that each composition weight number is:
Mixture pitch 40 ~ 50 parts,
Wilkinite 9 ~ 12 parts,
Styrene-butadiene rubber(SBR) solution 9 ~ 12 parts,
Mica powder 0.9 ~ 1.2 part,
Trimethyllaurylammonium bromide 0.5 ~ 0.8 part,
Polystyrene 58 ~ 62 parts,
Dimethylbenzene 38 ~ 42 parts,
35 ~ 40 parts, water;
Wherein, mixture pitch is by No. 10 road bitumens 40% ~ 70%, and all the other are that No. 100 road bitumen configurations form; Styrene-butadiene rubber(SBR) solution is dissolved in solvent benzol by styrene-butadiene rubber(SBR), and the weight ratio of styrene-butadiene rubber(SBR) and solvent benzol is 1: 8.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, its reaction mechanism is: with mixture asphalt heating dewatering for first component, adds Trimethyllaurylammonium bromide and adds water and be heated to 60 DEG C, be stirred for component B with wilkinite.First, component B flows into mulser simultaneously and carries out first kernel response, generates first kernel response type oil-in-water-type waterproof.In the product first kernel response stage, the O in the abundant ingress of air of petroleum asphalt based active reaction material
2, SO
2namely there is copolymerizable physical-chemical reaction in isoreactivity gas, first kernel response forms elastic colloid water-proof tack coat, water-proof tack coat itself is made to form preliminary force of cohesion, effectively can resist the delamination of water-proof tack coat, peeling and vehicle and grind broken, require that water-proof tack coat can not curing reaction completely simultaneously, otherwise easily cause being difficult to bond with surface layer bituminous concrete.The environmental protection of first kernel response waterproof, high temperature resistant, easy to operate, but cohesive force is poor.Add the waste polystyrene foam rubber cement of dissolving on this basis, under the effect of the reactive matrix polystyrene added, carry out second-order reaction and generate water in oil water-proof cold adhesive, form higher plastoelastic water-proof tack coat, namely the second-order reaction of product completes.Second-order reaction type water-proof adhesive has very high force of cohesion, the shear fracture of self can be resisted, after second-order reaction, the force of cohesion of water-proof bond material improves further, react the elastoplasticity water-proof binding basal plane solidify to form and there is the weather resistance more lasting than bituminous concrete pavement, second-order reaction imparts waterproof, the adhesive property of its excellence, improves cohesive force and resistance to low temperature, and adds seepage force.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, owing to belonging to second-order reaction type water-proof material, cohesive force is strong, special adaptation end of the bridge slope, corner and abrupt slope gate.Employ this water-proof cold adhesive to there will not be because slope is steep, turn round and cause asphalt concrete bridge surface to peel off to embrace phenomenon.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive; styrene-butadiene rubber(SBR) is as material modified; be mixed with mixture pitch by affiliated share by No. 100 pitches and No. 10 pitches; wilkinite is as dispersion agent; mica powder is heatproof, heat insulation, light reflecting material, and Trimethyllaurylammonium bromide is as cationic emulsifier, and polystyrene is as reactive matrix; dimethylbenzene makes solvent, water is as preparation medium.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, wilkinite is micro-is dispersion agent, has good water swellability, cohesiveness, dispersed, adsorptivity, thixotropy, thermostability, catalytic, anionresin.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, styrene-butadiene rubber(SBR) and pitch have stronger mutual solubility and cohesiveness.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, mixture pitch is main base, plays cementing waterproof action, and it affects greatly the configuration of coating and film performance.The easy dispersion and emulsion of the pitch that softening temperature is low, but the thermotolerance of film can be affected, easily glue pin during construction.If penetration of bitumens and extensibility too small, the splitting resistance of film and flexility can be caused to reduce.Therefore, the mixture pitch of preparation will meet following performance requriements: (1) is than being easier to emulsification; (2) softening temperature should not be too low; (3) low temperature extensibility and flexibility better.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, bentonite emulsified asphalt coating, the basis of former styrene butadiene rubber bentone thick emulsified asphalt water-proof paint is improved, with the addition of reactive matrix polystyrene, be modified to water-in-oil-type water-proof material by original oil-in-water-type water-proof material.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, anti-shearing force is strong, can stand road surface long duration load and measuring body requirement, can prevent infiltration from causing structure deteriorate.Not only there is good water resistance, and Absorbable rod road and bridge surface layer stress and noise, as the absorption layer of stress.Owing to itself having certain elasticity and plastic deformation ability, can bearing load and not being destroyed, alleviate road and bridge surface layers aging, delay highway bridge work-ing life.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, petroleum pitch has good cohesiveness, resistance to deterioration and waterproof ability, has waterproof and sealing function.
The present invention a kind of oil-in-water, water-in-oil second-order reaction type water-proof cold adhesive, technique is simple, and cost is low, easy to operate, and low temperature does not chap, and high temperature does not trickle, anti-aging, and the life-span is long, and by force, ultimate compression strength is high for water-repellancy and weathering resistance.
