AI Technical Summary

Problems solved by technology

Concrete speed studs have the characteristics of high strength and not easy to deform, but the toughness of concrete road studs is poor, and the damage to driving tires and road surfaces is relatively large; asphalt road studs have good toughness, but the softening point of asphalt is low. It begins to soften at about 50°C, and the highway surface can reach a high temperature of 70°C at noon in summer. Asphalt road studs will be severely deformed under the rolling of vehicles, losing their deceleration effect, and heating is required during the production of asphalt road studs.

Abstract

The invention relates to an epoxy resin base speed-reducing spike material for road engineering and a method for preparing the epoxy resin base speed-reducing spike material. The method comprises the following steps of: (1) preparing the following raw materials in parts by weight: 90 to 110 parts of epoxy resin, 30 to 50 parts of a curing agent, 5 to 7 parts of a flexibilizer, 3 to 5 parts of diluent, 2 to 3 parts of fiber, 40 to 60 parts of cement and 440 to 460 parts of quartz sand; and (2) mixing the epoxy resin, the flexibilizer, the diluent and the fiber, stirring uniformly, adding a mixture formed by the quartz sand and the cement, stirring uniformly, adding the curing agent, and stirring uniformly to obtain the epoxy resin base speed-reducing spike material. The epoxy resin base speed-reducing spike material has the advantages that (1), the material has the characteristics of high strength and good toughness; (2) the material is high in acid resistance, alkali resistance and solvent resistance, high in impact resistance and long in service life; (3) the material does not deform at high temperature and is high in high temperature resistance; (4) the material is easy to operate, short in production period and easy to mold, and heating is not needed in a preparation process.

Description

technical field [0001] The invention belongs to the field of road engineering materials, and in particular relates to an epoxy resin-based road stud material for road engineering and a preparation method thereof. Background technique [0002] There are many mountains and hills in the western part of my country, and the terrain is complex and changeable, which makes it very difficult to build roads and railways. Many of the roads built are not in good condition, and there are often continuous downhill sections of several kilometers or even tens of kilometers. The driving speed of vehicles on the continuous downhill section is fast, and traffic accidents are prone to occur, which has caused serious threats and losses to people's personal and property safety. According to statistics, traffic accidents in China have ranked first in the world for ten consecutive years. Of the 25 serious traffic accidents that occurred in 2012, 8 occurred on expressways (accounting for 32%). How...
