Abstract

The invention relates to a technological method for preparing a novel asphalt modifier with H2O2 as a raw material. The novel asphalt modifier material adopts low-molecular-weight and high-density polyethylene powder as a raw material. According to the technological method, under a water bath environment, the oxidizing modification reaction is carried out on the polyethylene material with H2O2 as an oxidizing agent by keeping certain pressure and under the effect of a catalyst to prepare the environment-friendly oxidized polyethylene asphalt modifier.

Description

technical field [0001] The present invention relates to a kind of H 2 o 2 The invention discloses a process for preparing a new type of asphalt modifier as a raw material. The oxidized polyethylene asphalt modifier material is prepared by using low molecular weight polyethylene powder to undergo an oxidation modification reaction in a water bath environment, and belongs to the chemical technology field. Background technique [0002] Oxidized polyethylene is an improved product of polyethylene. Since the molecular chain of oxidized polyethylene has a certain amount of carbonyl and hydroxyl groups, it is an excellent new bipolar material, so it is compatible with asphalt, asphalt fillers, pigments, and polar resins. The compatibility is significantly improved, and the lubricity and dispersion are better than polyethylene materials, and it also has coupling properties. Oxidized polyethylene material has special properties such as low viscosity, high softening point, and good ...
