Abstract
The invention relates to a pitch anti-stripping agent, which is prepared by evenly mixing the following materials in percentage by weight: 45 to 55 percent of nanometer calcium carbonate and 45 to 55 percent of yttrium chloride. When the pitch anti-stripping agent is added to the pitch, the 5 DEG C, the 10 DEG C and the 15 DEG C of the pitch is improved by 2 to 3 times compared with that of the substrate pitch; the penetration degree and the softening point of the pitch are also superior to that of the substrate pitch; the water stability of the pitch is superior to that of the substrate pitch; and the anti-strip performance of the pitch is 1 to 2 grades superior to the common No.70 and No.100 pitch mixtures.
Description
Technical field
The present invention relates to a kind of preparation of asphalt anti-stripping agent.
Background technology
In the bitumen for road use as do not add antistripping agent it is bad with the adhesion property of various building stones, easily aging, understand because of damage by water etc. and cause pitch to peel off, major cause is that common road asphalt wax content weighs, pitch adheres to badly with gathering materials, and under the effect of water, pitch has been sent out to peel off from surface of aggregate and caused; Antistripping agent commonly used is amine and phosphoric acid ester product, and thermostability is bad, is heated easily to decomposite obnoxious flavour, is unfavorable for environmental protection.
Summary of the invention
The objective of the invention is to provide a kind of good antistripping effect that both had, also the asphalt anti-stripping agent that can not work the mischief to environment.
The object of the present invention is achieved like this: a kind of asphalt anti-stripping agent is formed by following material uniform mixing, by weight percentage: nano-calcium carbonate 45-55%, Yttrium trichloride powder 45-55%.
Asphalt anti-stripping agent provided by the invention, add in the pitch after, 5 ℃, 10 ℃, 15 ℃ of bituminous improve 2-3 doubly than matrix pitch; Penetration degree and softening temperature also are better than matrix pitch; Water stability is better than matrix pitch; Antistrip performance is better than an asphalt 1-2 grade common No. 70, No. 100.
Embodiment
Embodiment 1: nano-calcium carbonate 45Kg with stir after Yttrium trichloride powder 55Kg normal temperature mixes, obtain asphalt anti-stripping agent.
Embodiment 2:
With nano-calcium carbonate 50Kg with stir after Yttrium trichloride powder 50Kg normal temperature mixes, obtain asphalt anti-stripping agent.
Embodiment 3:
With nano-calcium carbonate 55Kg with stir after Yttrium trichloride powder 45Kg normal temperature mixes, obtain asphalt anti-stripping agent.
When asphalt anti-stripping agent used, add-on was the 0.5-1% of pitch emphasis by weight percentage.
The stability of asphalt mixture laboratory report that has added this asphalt anti-stripping agent sees Table 1:
Stability of asphalt mixture can laboratory report table 1
Added the bituminous material ageing resistance laboratory report table 2 of this asphalt anti-stripping agent:
Bituminous material resistant to thermal aging performance laboratory report table 2
The bituminous material antistrip performance laboratory report that has added this asphalt anti-stripping agent sees Table 3
Asphalt mixture material antistrip performance laboratory report table 3
Claims (1)
1. an asphalt anti-stripping agent is characterized in that: formed by following material uniform mixing, by weight percentage: nano-calcium carbonate 45-55%, Yttrium trichloride powder 45-55%.
