Embodiment 1

[0032] A kind of modified asphalt provided by the present embodiment, Qilu No. 70 matrix asphalt and Ricoh brand printer waste toner, the added quality of this toner accounts for 2% of the modified asphalt, aluminate coupling agent and stearic acid synergist The added mass accounts for 0.5% and 0.125% of the modified asphalt respectively. The preparation method of this modified asphalt comprises the following steps:

[0033] Put Qilu No. 70 base asphalt in an oven at 160°C to preheat until softened, weigh the carbon powder in proportion, preheat it to 100°C, add the preheated carbon powder to Qilu No. 70 base asphalt while stirring, and then put the Put the container with asphalt into a constant temperature heating mantle for high-speed shearing. The shearing temperature is 160°C, the shearing rate is 3800r / min, and the shearing time is 25min. Then weigh the aluminate coupling agent in proportion and add it to In asphalt, the shear temperature is 160°C, the shear rate is 3800...

Abstract

The invention provides modified asphalt, the modified asphalt comprises the following raw materials: a matrix asphalt, waste powdered carbon obtained from a printer or a copy, aluminic acid ester and stearic acid; a preparation method of the modified asphalt comprises the following steps: 1)respectively preheating the matrix asphalt and the waste powdered carbon; 2)mixing the preheated waste powdered carbon and the matrix asphalt to obtain a mixture; 3)simultaneously stirring or shearing the mixture while heating; 4)adding an aluminic acid ester coupling agent and continuously stirring or shearing; and 5)adding a stearic acid synergist and stirring or shearing to obtain the modified asphalt. The modified asphalt has the advantages of good technology performance and low price, the waste powdered carbon in a toner cartridge of the printer or a copy machine can be reused, the modified asphalt has good social, economic and environmental protection benefits; the softening point of the matrix asphalt can be increased by 3-8 DEG C, so that the high temperature stabilization performance of the asphalt mixture can be increased, pavement track is reduced, water stabilization performance is increased, and the low temperature performance grade of the modified asphalt can be kept or improved.

Description

technical field [0001] The invention relates to a modified asphalt, in particular to a method for preparing the modified asphalt by blending waste carbon powder after use of a printer or copy, an aluminate coupling agent and a stearic acid synergist. Background technique [0002] Printer is one of the most common equipment in daily office. The laser printer commonly used in the office is actually a "big household" of environmental pollution. The harm it brings to your body is comparable to that of cigarettes. According to statistics, in 2008, more than 45 million ink cartridges and 4 million toner cartridges were discarded in my country, with a total volume of more than 400,000 cubic meters. If these discarded consumables were loaded into train carriages, it would be enough to fill 5,000 cartridges. According to the calculation of the environmental protection department, one drop of residual ink pollutes 60 cubic meters of water, and one discarded ink cartridge pollutes 1 cu...
