Abstract
The invention discloses modified asphalt, which is prepared by steps of mixing waste rubber abrasive powder and hydroxyethyl acrylate according to the weight ratio of 1: 1.04 and adding the mixture to the original heated asphalt. The modified asphalt has the beneficial effects that the waste rubber resource is reasonably utilized; and meanwhile, by adding the rubber, the smoke and dust of the asphalt can be effectively reduced, and the harm of the asphalt to the environment and the human body can be alleviated.
Description
Technical field
The present invention relates to a kind of modifying asphalt.
Background technology
The chocolate complex mixture that pitch is made up of hydrocarbon polymer and the nonmetal derivative thereof of different molecular weight is in a liquid state, semi-solid state or solid-state, is a kind of waterproof and dampproof and rot-resistant organic gel gel material.Be used for industry such as coating, plastics, rubber and surfacing etc.Glance coal and dust can cause poisoning with polluting skin through respiratory tract, and dermatitis, blurred vision, eye conjunctivitis, uncomfortable in chest, symptoms such as abdomen is sick, palpitaition, headache take place.Prove that through scientific experimentation 3,4 contained benzopyrenes are the one of the main reasons that cause skin carcinoma, lung cancer, cancer of the stomach and esophagus cancer in pitch and the glance coal.Live in the air that polluted by pitch, easily immunogenicity descends.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned defective of the prior art, and a kind of waste material resource of rationally utilizing is provided, and can effectively reduce the modifying asphalt of pitch dust simultaneously.
To achieve these goals, technical scheme provided by the invention is: a kind of modifying asphalt is will be behind the waste old abrasive dust to mix by weight 1:1.04 with Hydroxyethyl acrylate, is added to obtain in the fossil bitumen of heating again.
Further, above-mentioned a kind of modifying asphalt, the fineness of described waste old abrasive dust is the 30-50 order.
Further, above-mentioned a kind of modifying asphalt, described waste old are one or more in cis-1,4-polybutadiene rubber, chloroprene rubber or the styrene-butadiene rubber(SBR).
Further, above-mentioned a kind of modifying asphalt, the Heating temperature of described fossil bitumen is 200-230 ℃.
Further, the speed that above-mentioned a kind of modifying asphalt, the mixture of described waste old abrasive dust and Hydroxyethyl acrylate add the heating fossil bitumen is that pitch per ton per hour adds 180 kilograms of mixtures.
Beneficial effect of the present invention is: a kind of modifying asphalt provided by the invention, rationally utilized the waste rubber resources that can't regenerate, and simultaneously, owing to added rubber, can effectively reduce the flue dust of pitch, reduced the harm of pitch to environment and human body.
Embodiment
Embodiment 1:
A kind of modifying asphalt, be to mix by weight 1:1.04 with Hydroxyethyl acrylate behind the waste old abrasive dust, be added to again and obtain in the fossil bitumen of heating, the fineness of waste old abrasive dust is the 30-50 order, waste old is one or more in cis-1,4-polybutadiene rubber, chloroprene rubber or the styrene-butadiene rubber(SBR), the Heating temperature of fossil bitumen is 200-230 ℃, and the speed that the mixture of waste old abrasive dust and Hydroxyethyl acrylate adds the heating fossil bitumen is that pitch per ton per hour adds 180 kilograms of mixtures.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment the present invention is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
