Abstract

The invention discloses an activated waste rubber powder modified asphalt material. Firstly, a hydrogen peroxide / potassium ferrate complex oxidizing system is used for performing oxidation treatment on waste rubber powder, so that a large number of active groups are exposed at the surface thereof; then, silane coupling agent hydrolysate is used for performing modification treatment on the waste rubber powder; an efficient activity effect is achieved, so that the compatibility of the obtained waste rubber powder and the substrate asphalt is better; the performance of the composite asphalt material is improved; in addition, activated palygorskite can improve the temperature resistant performance and the anti-aging performance of the composite asphalt material; waste gas in the production process can also be adsorbed; the dirt is reduced; under the crosslinking catalysis effect of benzaldehyde, the ductility of the composite material is effectively improved; the waste gas release quantity is further controlled; the prepared modified asphalt material has excellent performance and environment-friendly effect; the economic values are high.

Description

technical field

[0001] The invention relates to the technical field of asphalt materials, in particular to an activated waste rubber powder modified asphalt material. Background technique

[0002] my country is a big country in tire production and automobiles. With the rapid increase of family car ownership, a large number of waste tires are produced every year. How to effectively recycle these waste tires and prevent environmental pollution has very important practical significance and huge economic value. . At present, the more common waste tire recycling methods mainly include direct utilization of prototypes, incineration to generate heat, retreading of old tires, production of recycled rubber, and production of vulcanized rubber powder. Among them, the production of rubber powder from waste tires is a combination of environmental protection and resource recycling. A promising recycling method is also the best form of utilization that we advocate for the development of a...
