Abstract

The invention provides a modified rubber cement seam repairing material for a bridge. A preparation method of the modified rubber cement seam repairing material comprises the following steps: firstly, preparing modified rubber powder: weighing the following components in parts by weight: 100 parts of natural rubber, 5 to 20 parts of glycidyl methacrylate, 5 to 10 parts of potassium stearate and 3 to 5 parts of calcium lignosulfonate; uniformly mixing and adding a mixture into an internal mixer, wherein the internal mixing time is 5min to 8min and the internal mixing temperature is 110 DEG C to 120 DEG C; adding 3 to 10 parts of 8 to 10 parts of high-styrene resin by weight and mixing for 10min to 15min; putting a mixed mixture on an extruder and extruding. According to the modified rubber cement seam repairing material for the bridge, provided by the invention, the modified rubber powder is added to increase the porosity of concrete and the deformation of rubber powder particles absorbs sound waves so that road surface noises are reduced; inorganic materials including talcum powder and quartz powder are introduced into modified rubber powder-emulsion so that a modified rubber powder-emulsion-inorganic powder three-dimensional net-shaped structure can be formed in a cement system and the material has a very good enhancing effect on a cement matrix system; the material has strong physical and chemical stability.

Description

technical field [0001] The invention relates to a modified rubber cement seam filling material for bridges, which belongs to the field of bridges. Background technique [0002] The traditional bridge repair material is ordinary cement concrete, which usually needs to be cured for 14 to 28 days and cannot reach the ideal strength. However, the road is closed for a long time, which seriously affects the normal driving of vehicles, especially on expressways with large traffic volumes. , It is easy to cause traffic congestion. During the maintenance period, traffic is often blocked due to traffic interruption and blockage, which has a great impact on the lives and production of the masses. "The expressway is not high-speed", and the social response is relatively large. requirements are getting higher and higher. The existing maintenance and repair materials obviously still have inconvenience and defects in structure and use, and need to be further improved urgently, in order to...
