Embodiment 1

[0034] An epoxy bitumen filling material suitable for embedded tracks, comprising A component and B component, the components are as follows in parts by weight:

[0035] Component A: 100 parts of epoxy resin;

[0036] Component B: 30 parts of base asphalt material, 1 part of modifier, 70 parts of compatibilizer, 80 parts of curing agent, 60 parts of rubber particles;

[0037] The base asphalt material is 70# petroleum asphalt, the epoxy resin is bisphenol A epoxy resin, the modifier is acrylic acid, and the compatibilizer is R-NH 2 , wherein R is a substance of 18 alkyl groups, the curing agent is selected to be a mixture of polyamide and modified amine in a ratio of 1:3, and the rubber particles are selected to be 20 mesh.

[0038] The above-mentioned preparation method of component B in the epoxy asphalt filling material suitable for embedded track comprises the following steps:

[0039] (1) Heat 30 parts of base asphalt material to 130°C, add 1 part of modifier, and stir ...

Embodiment 2

[0043]The difference from Example 1 is that the weight ratio of the components in component B of the epoxy asphalt filling material is: 60 parts of base asphalt material, 2 parts of modifier, 65 parts of compatibilizer, 90 parts of curing agent, and rubber particles. 60 servings. The base asphalt material is 70# petroleum asphalt, the epoxy resin is bisphenol A epoxy resin, the modifier is maleic anhydride, and the compatibilizer is R-NH. 2 , wherein R is a substance of 18 alkyl groups, the curing agent is selected to be a mixture of polyetheramine and modified amine in a ratio of 1:1, and the rubber particles are selected to be 40 mesh.

Embodiment 3

[0045] The difference from Example 1 is that the weight ratios of the components in component B of the epoxy asphalt filling material are: 90 parts of base asphalt material, 3 parts of modifier, 100 parts of compatibilizer, 50 parts of curing agent, and rubber particles. 60 servings. The base asphalt material is 70# petroleum asphalt, the epoxy resin is bisphenol A epoxy resin, the modifier is maleic anhydride, and the compatibilizer is R-NH. 2 , wherein R is a substance of 18 alkyl groups, the curing agent is selected from phenalkamine curing agent, and the rubber particles are selected as 60 mesh.

Abstract

The invention discloses an epoxy rubber asphalt filling material suitable for an embedded track and a preparation method and application thereof. The epoxy rubber asphalt filling material comprises a component A and a component B in a weight ratio of 1: (1-10); the component A is epoxy resin, and the component B is composed of the following components in percentage by weight: 20-120% of a matrix asphalt material, 0-10% of a modifier, 60-120% of a compatibilizer, 80-140% of a curing agent and 20-80% of rubber particles. The epoxy asphalt material has good compression and tensile properties, and can meet the rigidity requirement of an embedded track system; the low-temperature performance is good, good vibration and noise reduction performance is kept in a large temperature range, and certain aging resistance and fatigue resistance are achieved; the environment is protected.

Description

technical field [0001] The invention relates to the field of building polymer materials, in particular to an epoxy rubber asphalt filling material suitable for embedded tracks and a preparation method and application thereof. Background technique [0002] Compared with other types of vibration reduction and noise reduction rails, the embedded track is characterized by the continuous support of the steel rail, and 2 / 3 of the main noise source of the steel rail is embedded in the polymer filling material, and the vibration reduction of the polymer filling material is added. Energy consumption makes it have better vibration and noise reduction performance. The mechanical properties of the embedded track structure determine that the polymer filling material should have a certain compressive strength, and the bonding strength with steel, cement and other materials should be large, and it has good vibration and noise reduction performance. Most of the existing filling materials i...
