Abstract
The invention discloses the production method of water-proof coating for road and bridge which comprises the steps of, (1) heating asphalt for dehydration, (2) preparing oil emulsion, (3) asphaltization, (4) placing emulsified asphalt in container, charging polychloroprene latex, agitating homogeneously, charging powder gasket material, defoaming agent.
Description
Technical field
The present invention relates to the making method of a kind of road and bridge waterproof paint.
Background technology
In the prior art, the improper meeting of bridge surface waterproofing material causes the bridge floor infiltration, problems such as making steel bar corrosion, mat formation that layer peels off, alkali-aggregate reaction, the concrete expansion that caused by steel bar corrosion etc. are badly damaged has had a strong impact on the weather resistance and the normal work-ing life of bridge.Present waterproof paint to the requirement of high thermal resistance be non-foaming, do not ftracture, do not slide, wrinkle resistant, lower temperature resistance requires flawless, not embrittlement, also require the cohesive strength height, the high temperature resistant temperature of existing waterproof paint is 80 ℃, low temperature resistant temperature is-10 ℃, cohesive strength is 0.2Mpa, so its performance can not reach requirement.
Summary of the invention
The object of the invention provide a kind of excellent combination property road and bridge waterproof paint making method.
The technical solution of the utility model is: a kind of road and bridge waterproof paint making method, it is characterized in that: it comprises the steps
(1), pitch thermal dehydration; Is weight 35 parts～45 parts No. 100 road bitumens, 15 parts～25 parts No. 10 road bitumen mixing post-heating dehydrations, and the maintenance temperature of heating is 120～140 ℃;
(2), preparation emulsion; With weight is that 55 parts～65 parts deionized water, 0.3 part～0.5 part stablizer, 0.1 part～0.15 part octadecyl trimethyl ammonium chloride emulsifying agent, 0.005 part～0.015 part Walocel MT 20.000PV are put into container and stirred and be warming up to 60～70 ℃;
(3), asphalt emulsification; Pitch after the dehydration and the emulsion for preparing are carried out emulsification with mulser, get emulsified bitumen;
(4), emulsified bitumen is put into container, under agitation condition, add 20 parts～30 parts polychloroprene latex, after stirring, under agitation condition, put into 10 parts～20 parts powder filler slowly, and add defoamer, finish up to the back that stirs, finished product.
The present invention compared with prior art has following advantage:
Resistance to elevated temperatures excellence of the present invention can reach 160 ℃, and resistance to low temperature can reach-20 ℃, and cohesive strength is significantly brought up to 0.47Mpa, have good workability, and not stifled rifle during construction, surface filming is fast, excellent storage stability.
Embodiment
A kind of road and bridge waterproof paint making method, it comprises the steps
