Abstract

The invention relates to a method for preparing a bulking agent of epoxy resin modified asphalt. Epoxy resin modified asphalt material is applicable to pavement of a high-grade road, pavement of steel bridge deck and the like. The method for preparing the bulking agent of the epoxy resin modified asphalt is characterized by comprising the following steps of: 1) selecting the following raw materials in parts by weight: 100 parts of fatty acid, 150-250 parts of epoxy resin, 3-4 parts of catalyst and 580-610 parts of organic solvent for spare use; and 2) dispersing the fatty acid and the epoxy resin into the organic solvent, and adding the catalyst, and heating for 3-5 hours at the temperature of 100-150 DEG C so as to obtain the bulking agent of the epoxy resin modified asphalt. The bulkingagent prepared by the method provided by the invention can cause mixing of asphalt and the epoxy resin to be more uniform.

Description

technical field [0001] The invention relates to a building material, in particular to a preparation method of a compatibilizer for epoxy resin modified asphalt. Epoxy resin modified asphalt materials are suitable for the pavement of high-grade roads and steel bridge decks. Background technique [0002] Asphalt is an important building waterproof material and building material. Engineering asphalt generally comes from by-products of petroleum refining. It is a thermoplastic material that is cheap and easy to obtain. It is widely used in transportation, agriculture, water conservancy projects, industry, and civil use. and other departments. When unmodified asphalt is used in road pavement, due to its strong temperature sensitivity, it is easy to age, it will soften and become sticky at high temperature, and cracks will occur due to the shrinkage of internal stress at low temperature. If the hardness is not enough, after repeated rolling, road surface diseases such as ruts an...
