Abstract

The invention provides a durable epoxy resin joint filling material and a preparation method thereof. The durable epoxy resin joint filling material comprises a component A and a component B, whereinthe component A is mainly prepared from the following raw materials: 50-100 parts of a bisphenol A epoxy resin, 10-20 parts of a phenolic epoxy resin, 5-10 parts of a hydrogenated bisphenol A epoxy resin, 50-100 parts of a flexible epoxy resin, 5-50 parts of an active diluent, 0-100 parts of an inorganic filler, 0-10 parts of a thixotropic agent, 1-3 parts of an anti-aging agent, 1-3 parts of an antioxidant and 1-3 parts of an ultraviolet absorbent; the component B is mainly prepared from the following raw materials: 10-265 parts of a modified amino curing agent, 0-3 parts of a curing agent and 0-3 parts of a curing accelerator. The component A can be mixed with the component B with the modified amino curing agent to form a solid with particularly good durability, a building joint filled with the solid is good in sealing property, and leakage caused by cracking, deformation and the like of the solid can be avoided.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a durable epoxy resin caulking material and a preparation method thereof. Background technique [0002] The rapid development of high-speed railways in recent years has become China's business card and one of the representatives of China's rapid technological development. Since the implementation of the "Medium and Long-term Railway Network Planning" in 2004, my country's high-speed railway development has achieved remarkable results, playing an important role in promoting economic and social development, ensuring and improving people's livelihood, supporting the implementation of major national strategies, and enhancing my country's comprehensive strength and international influence. Based on "four vertical and four horizontal", form a high-speed railway network with "eight vertical and eight horizontal" main passages as the skeleton, regional connection lines, and int...
