Preparation process of asphalt modifier

Abstract

The invention relates to a preparation process of an asphalt modifier. The preparation process comprises a workbench, a stirring device and a grinding device; the stirring device is fixedly mounted atthe upper end of the workbench; the grinding device is mounted on the lower side of the stirring device; the stirring device comprises a stirring cylinder, a first motor, a rotating column, a spiralbelt, a stirring frame, a feeding hopper and a screening frame; and the grinding device comprises a push rod, a support rod, a movable plate, a large ball, a bearing, a rectangular long plate, a fixedplate, a control rod and a protruding block. Mixed raw materials are evenly stirred through the stirring device and screened till particles meeting the standard are completely collected, the particles with the large size are ground through the grinding device, and the ground particles are ground again through the stirring device until the particle size of all the raw materials meets the standard.

Description

technical field [0001] The invention relates to the field of asphalt modifier processing, in particular to a preparation process of the asphalt modifier. Background technique [0002] Asphalt modifier refers to a natural or synthetic organic or inorganic material added to asphalt or asphalt mixture, which can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt. The main purpose of the agent is to improve the road performance of asphalt mixture at high temperature, reduce the permanent deformation at high temperature, improve its anti-rutting, anti-fatigue, anti-aging, and resist low-temperature cracking or increase anti-fatigue ability at low temperature, etc. Performance, so that it meets the requirements of traffic conditions during design use. [0003] In the process of preparing the asphalt modifier, due to the quality requirements of the modifier, the following problems exist in the actual operation process: [0004] (1) The traditi...

AI Technical Summary

Problems solved by technology

[0004] (1) Traditional asphalt modifier preparation equipment generally only stirs the modifier evenly, and the larger particles in the modifier are difficult to be found, thus affecting the quality of modified asphalt

[0005] (2) After the traditional asphalt modifier preparation equipment sieves the raw material after stirring, the larger raw material particles that do not meet the standard are separated from the uniformly stirred raw material, thereby affecting the mixing ratio of the raw material, resulting in The use performance of raw materials is reduced
