Description
Technical field
The present invention relates to foamed asphalt production and asphalt mixture warm-mixing construction, Bituminous Pavement Cold for pavement engineering are again
Used in the technology such as life, modified pitch foaming agent manufacture, more particularly to a kind of for foamed asphalt and modified pitch in drip
Blue or green foaming agent and preparation method thereof.
Background technology
Foamed asphalt is that hard pitch is contacted with water, because of the Colophonium bubble that moisture vaporization in Colophonium forms steam bubble and formed
Foam system.As foamed asphalt can be rolled with aggregate blending, compound at relatively low temperatures at a lower temperature,
Well received in the construction of Colophonium warm mix, old asphalt pavement regeneration technique.
Two parameters for evaluating asphalt foaming effect are expansion rate and half-life.Expansion rate refers to that Colophonium is foamed with water mix
The maximum volume for reaching afterwards and the ratio of the unexpanded front volume of Colophonium；Half-life refers to the maximum volume of foaming to volume-diminished extremely
Half elapsed time, represented with the second (S).Expansion rate is bigger, and foamed asphalt is more abundant with the contact that gathers materials, the bubble of mixing
Foam quality of asphalt mixtures is better；Half-life is longer, foamed asphalt with gather materials to take the working time in longer, be conducive to carrying
The quality of high plate form rubber.At present, the key technology of production foamed asphalt is control using accurate water consumption and obtains
Obtain expansion rate most preferably.In actual production, typically require that more than 10 times of expansion rate, half-life typically require to be more than 8S.
Current technology, due to simply by adding water rate control expansion rate and half-life, regulating measure be limited, when
The viscosity of Colophonium is higher with when needing long period mix, and current foaming agent can not meet construction requirement.
Content of the invention
The purpose of the present invention is to propose to a kind of expansion rate that can improve asphalt foaming and half-life, improve foamed asphalt
Stability, the formula for improving the asphalt foaming agent of Colophonium high temperature performance are constituted and preparation method.
The asphalt foaming agent of the present invention, its constituent are that natural emulsion and industrial latex, the mass ratio of two kinds of compositions are
100：0-0:100；Its solid content mass percent is in 1-80%, preferably 30-80%.
The preparation method of the asphalt foaming agent of the present invention：It is by Heveatex and industrial latex in mass ratio 100：0-0:
100 scopes, at a temperature of 10-40 DEG C, in reactor, 30-50 turn/min speed is uniformly mixed prepared asphalt foaming agent.
Heveatex of the present invention, refers to a kind of milky white liquid from gained in the rubber tree of cultivation, is a kind of life
Thing sinteticses, in 20-50%, its filming performance is good for solid content, and wet gel strength is high, springiness.
Commercial latex of the present invention, refers to the butylbenzene class latex of commercial synthesis, NBR latex, polychloroprene latex, SBS glue
Breast, solid content is in 1-80%.
The using method of above-mentioned asphalt foaming agent is according to traditional asphalt foaming agent addition, is added in Colophonium and sends out
Bubble production foamed asphalt.
The foaming agent of the present invention can not only improve expansion rate and the half-life of asphalt foaming, improve stablizing for foamed asphalt
Property, and Colophonium high temperature performance is significantly improved, improve the property of Colophonium.
