Abstract
The invention relates to a high performance and low cost modified pitch, which is prepared by heating and stirring the following raw materials according to weight ratio: 3 to 10 percent of waste polyethylene used for packing, 85 to 96 percent of matrix pitch, and 0.1 to 1.5 percent of dispersant and surfactant. The modified pitch of the invention is verified, by a needle penetration test, a ductility test, a softening point test, and a freezing-breaking test which is performed by Seepage Proofing Institute of Xi'an University of Technology, that the modified pitch can improve the comprehensive performance of high grade pitch highway, so as to endow the highway with good durability, abrasion resistance, softening resistance at high temperature and cracking resistance at low temperature, and can lengthen the service life and loading capacity of roadways and dams.
Description
Technical field
The present invention relates to a kind of high-grade highway that utilizes package waste polymer to make, dam modifying asphalt.
Background technology
Along with the development of China's packing business and plastics industry, make plastics when promoting the well-being of mankind, also cause pollution to environment.The recycling present situation of waste plastic goods allows of no optimist, and wherein, useless PE occupies very scores more than normal.Meanwhile, highway, dam can not satisfy the growing high-grade heavily loaded road surface and the demand of dam with the bituminous performance, high grade pavement exists such as problems such as high temperature rut, road surface damage by water evil, cold district bituminous pavement temperature draw seams, and the bituminous performance is badly in need of improving.White pollution and high-grade highway, dam improve with the bituminous performance that all fish is to be solved.At home in the patent, also do not find the bibliographical information that utilizes the useless PE of packing high-grade highway to be carried out modification with pitch according to data-searching that the applicant carried out.
Summary of the invention
The objective of the invention is to, provide package waste polymer-waste polyethylene (PE) preparation in a kind of daily life that utilizes after the recovery a kind of modifying asphalt that is used for high-grade highway, dam, with the heavily loaded road surface that adapts to high-grade highway and the carrying over-all properties of dam.
To achieve these goals, technical solution of the present invention is: a kind of high-performance, low-cost modified asphalt, the raw material heated and stirred that comprises following weight ratio forms: wherein packing waste polyethylene (PE) is (3-10) %, matrix pitch is (85-96) %, dispersion agent and surfactant comprise (0.1-1.5) %.
Described packing waste polyethylene (PE) is the package waste polymer in the daily life.
Described tensio-active agent is that polyoxyethylene sorbitol is joined vinegar, and dispersion agent is that the tetramethylolmethane stearic acid is cruel.Tensio-active agent and dispersion agent can equal proportion add.
The above-mentioned process for preparing modified asphalt that is used for high-grade highway, dam comprises the following steps: 1) packing of will giving up polymkeric substance is that to be cut into about 1.5x2.scm fragment after drying standby through cleaning by the package waste polymer in the daily life; 2) be that 200-300 rev/min agitator kettle internal heating stirs with above-mentioned package waste polyethylene (PE) fragment (3-10) % with inserting rotating speed after matrix pitch (85-96) % mixes, add dispersion agent (the tetramethylolmethane stearic acid is cruel) in the whipping process, tensio-active agent (polyoxyethylene sorbitol is joined extremely) is % (0.1-1.5), churning time 1.5-2 hour, whipping temp is controlled to be 180 ℃-200 ℃, after useless packing is abandoned polyethylene (PE) and all is melted into heated bitumen, there are not throw out and agglomerate in the mixed solution, denseness evenly stops heating and stirs, and promptly can be made into to be used for high-grade highway, the modifying asphalt of dam.
Modifying asphalt of the present invention is through penetration degree, extensibility, softening temperature and freeze disconnected evidence by what antiseepage institute of Xi'an University of Technology carried out, modifying asphalt of the present invention can improve the over-all properties of high-grade bituminous highway, make it have favorable durability, wear resistance, anti-softening, the low temperature cracking resistance of high temperature, can prolong road surface, dam work-ing life and carrying capacity.And have characteristics such as purposes is wide, less investment, cost is low, quality is high, protection environment, modification regeneration.Have tangible economic benefit and remarkable social benefit.Solve or alleviated white pollution problems, reached the purpose of protection environment, utilization of waste material and saving investment.
Embodiment
According to the present invention, carried out the specific examples experiment.It is matrix pitch that example is selected Kelamayi 70# for use, and concrete proportioning is: packing waste polyethylene (PE) 10%, matrix pitch 89.5%, dispersion agent (the tetramethylolmethane stearic acid is cruel), tensio-active agent (polyoxyethylene sorbitol is liquor-saturated cruel) 0.5%; Tensio-active agent and dispersion agent add by equal proportion, in temperature is that 180-200 ℃, rotating speed are to stir 1.5-2 hour in 200-300 rev/min the agitator kettle, after useless PE all is melted into heated bitumen, there are not throw out and agglomerate in the mixed solution, denseness evenly stops heating and stirs, and can obtain containing the modifying asphalt of packing waste polyethylene (PE).Above-mentioned packing waste polyethylene (PE) adopts discarded milk bag to be cut into about 1.sx2.scm fragment through cleaning to dry.Is evidence when packing waste polyethylene (PE) accounts for 3 of compound total mass? 10%, all can obtain the qualified modifying asphalt that is used for high-grade highway, dam.Carry out the experiment of softening temperature, penetration degree, extensibility to getting the pitch that contains after packing waste polyethylene (PE) 10% the modification in the foregoing description, and make comparisons with unmodified pitch, experimental data sees the following form:
Penetration degree experimental data (0.1mm) (table 1)
The softening temperature experimental data (℃) (table 2)
Extensibility experimental data (mm) (table 3)
Claims (3)
1. a high-performance, low-cost modified asphalt, comprise that the raw material heated and stirred of following weight ratio forms: wherein packing waste polyethylene is 3-10%, and matrix pitch is 85-96%, dispersion agent and surfactant comprise 0.1-1.5%.
2. high-performance as claimed in claim 1, low-cost modified asphalt is characterized in that: the packing waste polyethylene is the package waste polymer in the daily life.
3. high-performance as claimed in claim 1, low-cost modified asphalt is characterized in that: tensio-active agent is that polyoxyethylene sorbitol is joined vinegar, and dispersion agent is the tetramethylolmethane zirconium stearate.
