Abstract

The invention discloses a high-performance thermosetting epoxy asphalt material with wide temperature field and a preparation method thereof. The high-performance thermosetting epoxy asphalt material consists of a part A and a part B, wherein the part A comprises the following components in part by mass: 30 to 76 parts of modified asphalt with carboxyl or acid anhydride, 2 to 20 parts of monohydric alcohol or polyol or benzene ring plasticizer, 11 to 25 parts of aliphatic diacid, dimer acid or alkyd, 10 to 25 parts of fatty acid anhydride and 0.05 to 0.65 part of curing accelerator; and the part B is epoxy resin. The mass ratio of the part A to the part B is 2.2: 1-10: 1. The high-performance thermosetting epoxy asphalt material has the advantages of high strength, good flexibility, prominent high and low temperature performance, excellent fatigue resistance and environment friendliness, is applicable to the places with higher requirements such as expressways, roads and bridges and the like under various temperature conditions, and can be used as a road and bridge surfacing material, a waterproof roof material, a sealing agent and an advanced elastic damping de-noising material for the expressways.

Description

technical field [0001] The invention relates to a chemically modified asphalt, specifically a wide temperature range high-performance thermosetting epoxy asphalt material with excellent low-temperature performance and high-temperature performance and a preparation method thereof. Background technique [0002] Asphalt has good adhesion and water resistance, simple use process, and low cost. It has a wide range of applications in road paving, roof waterproofing, sealing and gluing, shock absorption and noise reduction. It is essentially a thermoplastic substance. This characteristic is manifested in the pavement paved with asphalt. In the high temperature season in summer, the road surface is prone to rutting under heavy loads, and in the cold season of winter, it is prone to temperature shrinkage cracks. The widespread use of beam structure bridges puts forward high requirements on the strength, deformation stability and fatigue durability of the pavement materials. As an i...
