Unsaturated resin composition as well as preparation method and a purpose thereof

Abstract

The invention provides an unsaturated resin composition as well as a preparation method and a purpose thereof, wherein the unsaturated resin composition contains a component A and a component B, the component A contains an acrylic resin or a prepolymer thereof, a diluent, a toughening agent, a thixotropic agent and other assistants; the component B contains a peroxide initiator and a plasticizer,and the mass ratio of A to B is 100:1 to 100: 50. The preparation method of the composition is simple and is beneficial to rapid production. A repairing material containing the composition and used as a railway plate type ballastless track cement road bed, a boss resin layer and a mortar filling layer solves the problems of poor water resistance, impact resistance, aging resistance and low temperature resistance existing in the traditional repairing material.

Description

Technical field

[0001] The present invention relates to an unsaturated resin composition and a preparation method thereof, and an unsaturated resin composition repair material, which is mainly used as a repair material for railway slab ballastless track cement track bed, boss resin layer and mortar filling layer . Background technique

[0002] my country is currently constructing large-scale passenger dedicated lines and high-speed railways. By 2020, the goal is to build 10,000 kilometers of dedicated passenger lines, form a “four vertical and four horizontal” passenger dedicated line skeletons, and build a railway in the Bohai Rim, Yangtze River Delta, and Pearl River Delta regions The rapid passenger transportation system railway is 2000 kilometers. The passenger dedicated line is divided into 250 km / h and 350 km / h according to the design speed. According to the track structure, it is divided into two types: ballasted track and ballastless track. The ballasted track structure i...
