Summary of the invention
The present invention is in order to solve the problems referred to above that exist in the prior art, provide a kind of can overcome the existing bridge pier life-span short, have shortcoming such as potential safety hazard, and have the concrete column of the coating of anticorrosion waterproof.
It is a kind of concrete column of coating that the present invention solves the technical scheme that the prior art problem adopted, and comprises concrete column, the concrete column of said coating the top layer be coated with the liquid rubber spray-coating material coating.
Said liquid rubber spray-coating material coating is 1-3 ㎜.
Said liquid rubber spray-coating material is divided into A, two kinds of components of B; Said A component is an anion liquid body rubber asphalt emulsion; Said B component is a coagulant solution; Said A component is represented with mass percent, and liquid rubber asphalt emulsion weight solid content is 50-75%, wherein, rubber latex 1-65%, asphalt emulsion 20-97%, anionic dispersing agents 0.0025-2.5%, anion surfactant 0.0025-4%; Said B component is represented with mass percent, is 3-18% the aqueous solution by calcium chloride, the formulated concentration of compound ferro-aluminum mixed with polymers; The spraying Capacity Ratio of said liquid rubber spray-coating material B component and A component is 1/15-1/3.5.
Spraying coating process is for to be respectively charged into the A for preparing, B component in the proportion container separately; Under the promotion of dynamical system, A component and B component run to spray gun separately respectively through two pipelines, and two muzzle slope inwardly during spraying; Spray angle is aimed at the same district of the object basal plane face that needs spraying simultaneously; The moment of material ejection forms atomization process, and two components are fully mixed before arriving basal plane or when arriving basal plane, film thereby form more uniform rubber asphalt.Two components are 350-600mm in the joint distance of mixing the spraying face of arrival.
The invention has the beneficial effects as follows: the present invention is simple in structure, and the liquid rubber spray-coating material coating of spraying has the performance of powerful chemical resistance, anti-strong acid, alkali, salt; Very high anti-puncture resistance; Film forming thickness>2 ㎜ have good self-healing function; Do not scurry water between glued membrane and substrate, really reach the skin-type waterproof requirement; Anti-ozone aging and anti-ultraviolet property are good, projected life>50 year; With all traditional waterproofing materialss affinity is very arranged, adhere to fully with most foundation structures; Save time, laborsaving, efficient is high, can practice thrift and reduce capital construction cost.
The specific embodiment
The present invention will be described below in conjunction with embodiment:
Embodiment 1.
A kind of concrete column of coating comprises concrete column 1, and the top layer of the concrete column of coating is coated with liquid rubber spray-coating material coating 2.Liquid rubber spray-coating material coating 2 thickness are 1-3 ㎜.
Through detection,
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
