Abstract

The invention relates to the technical field of modifiers for asphalt, concretely to an economical asphalt odor removing and reinforcing modifier agent and a preparation method and applications thereof. The modifier comprises 4-8 parts of a dispersing agent, 10-24 parts of an odor removing agent, 16-24 parts of a tackifier, 10-12 parts of a reinforcing agent, and 15-32 parts of an anti-aging agent. The preparation method is to evenly mix the components and carry out forming and granulation by a screw extruder under the temperature condition of 50 DEG C to obtain the economical asphalt odor removing and reinforcing modifier agent finished product. The economical asphalt odor removing and reinforcing modifier agent and the preparation method and applications thereof provided by the inventionhave the advantages of low production cost, odor removal, good reinforcing modification effect and convenient production and use.

Description

technical field [0001] The invention relates to the technical field of modifiers for asphalt, in particular to an economical asphalt odor-reinforcing modifier with low cost, clean odor, good reinforcement modification effect and convenient production and use, as well as its preparation method and application. Background technique [0002] Asphalt, especially rubber powder modified asphalt (Asphalt Rubber, referred to as AR) is a commonly used road material. However, in the prior art, the rubber powder modified asphalt will release a pungent odor during the production and construction process. The production temperature is 180-190 °C, the temperature is relatively high, the energy consumption is large, and the viscosity is large. Higher temperature is required, which is contrary to its environmental protection concept, and the oil stone of rubber asphalt mixture is much larger than that of ordinary SBS modified asphalt, and the comprehensive cost is higher than that of SBS mo...
