Abstract
The invention relates to a technology of modified asphalt regenerated by using waste plastic and waste rubber. In the preparation process of the modified asphalt, the waste plastic can improve the high temperature performance of the modified asphalt, the softening point of the asphalt is increased, the strength of the modified asphalt and concrete are strengthened, and road surfaces are prevented from becoming soft to cause the damages such as crushing, obstruction and tracks in summer. The waste rubber can improve the low temperature performance of the modified asphalt, the low-temperature ductility is improved, and the road surfaces are prevented from causing the phenomena such as net cracks, cracking and loosening in winter. The formula of the modified asphalt comprises the following components: 6-9% of waste rubber material I, 3-5% of coal tar I, 0.1-0.15% of activating agent I, 4-6% of polyethylene I, 0.3-0.85% of polypropylene and 80-87% of asphalt I.
Description
Described technical field:
The present invention relates to a kind of plastic waste, waste rubber regenerative use technology, is a kind of by plastics, waste rubber regeneration modified asphalt technology specifically.
Background technology:
The plastic waste of current use, waste rubber regenerative use technology are mostly that cost is high, waste starting material.
Summary of the invention:
The present invention is exactly for above not enough and devise and a kind ofly utilize discarded plastics, waste rubber regeneration modified asphalt technology.In the process preparing modifying asphalt, plastic waste can improve the high-temperature behavior of modifying asphalt, improves the softening temperature of pitch, enhancing modified pitch, concrete intensity, is unlikely to cause summer road surface softer, is formed to push, stop up the destructions such as bag, rut.Waste rubber can change the low-temperature performance of upper modifying asphalt, improves the ductility of low temperature, unlikelyly causes the road surface check crack in winter, be full of cracks, the phenomenon such as loose.
In order to reach the object of above-mentioned technology, a kind of plastic waste, waste rubber regeneration modified asphalt technology,
Its formula comprises:
Scrap rubber material one (6-9%),
Coal tar one (3-5%),
Activator one (0.1-0.15) %,
Polyethylene one (4-6%),
Polypropylene one (0.3-0.85) %,
Pitch one (80-87) %.
Specific implementation method:
Pitch is put in agitator, heat 150 degree, add scrap rubber material, keep temperature 160 degree, add coal tar and activator, after 30 minutes, add polyethylene, high-speed stirring, be warming up to 185 degree after 30 minutes, add polypropylene, reduce stirring velocity, after 30 minutes, obtain modified bitumen product.
Claims (2)
1. utilize plastic waste, waste rubber regeneration modified asphalt technical formula comprises: a talcum powder 30%-40%, dimethylbenzene 40-50%, acetone in proper, dibutylester 15-20%, chloroform 5-10%.This bonded adhesives cost of filling a prescription out is low, can be used on bonding timber, and ceramic tile bonds, ceramic bond.
2. it is characterized in that: pitch is put in agitator, heat 150 degree, add scrap rubber material, keep temperature 160 degree, add coal tar and activator, after 30 minutes, add polyethylene, high-speed stirring, 185 degree are warming up to after 30 minutes, add polypropylene, reduce stirring velocity, after 30 minutes, obtain modified bitumen product.
