Problems solved by technology

This is not only time-consuming and labor-intensive, but also closed traffic for a long time will cause potential safety hazards for vehicles, and traffic jams and traffic accidents are more likely to occur
Use new cement concrete to repair the damaged parts, the bonding effect between them is poor, and it is easy to cause damage again

Embodiment 1

[0012] Take 220kg of unsaturated resin, 8.8kg of curing agent, 8.8kg of accelerator, 12kg of polyester fiber, 450kg of yellow sand, and 600kg of stone in a stirrer and stir evenly before use. The solidification period is about 1-2 hours. The curing agent and accelerator are compound mixtures. The main component of the curing agent is benzoyl peroxide, and the main component of the accelerator is cobalt isooctanoate. Epoxy-modified unsaturated polyester resin is formed by polycondensation of polybasic acid and polyhydric alcohol, and can be purchased directly from the market.

Embodiment 2

[0014] Take 100kg of unsaturated resin, 0.2kg of curing agent, 0.2kg of accelerator, 0.5kg of polyester fiber, 100kg of yellow sand, and 200kg of stone in a stirrer and stir evenly before use. The solidification period is about 1-2 hours. The curing agent and accelerator are compound mixtures. The main component of the curing agent is benzoyl peroxide, and the main component of the accelerator is cobalt isooctanoate. Epoxy-modified unsaturated polyester resin is formed by polycondensation of polybasic acid and polyhydric alcohol, and can be purchased directly from the market.

Embodiment 3

[0016] Take 100kg of unsaturated resin, 1kg of curing agent, 1kg of accelerator, 5kg of polyester fiber, 500kg of yellow sand, and 1000kg of stone in a stirrer and stir evenly before use. The solidification period is about 1-2 hours. The curing agent and accelerator are compound mixtures. The main component of the curing agent is benzoyl peroxide, and the main component of the accelerator is cobalt isooctanoate. Epoxy-modified unsaturated polyester resin is formed by polycondensation of polybasic acid and polyhydric alcohol, and can be purchased directly from the market.

Abstract

The invention relates to an epoxy-modified unsaturated resin concrete used in roads and bridges, pertaining to a construction material, which is characterized in that the invention is synthesized by epoxy-modified unsaturated resin, curing agent, accelerant, polyester fiber, yellow sand and stone, and the proportion of the invention is: the unsaturated resin : the curing agent : the accelerant : the polyester fiber : the yellow sand : the stone is equal to 1: (0.002-0.01): (0.002-0.01) : (0.005-0.05) : (1-5) : (2-10). The invention can rapidly maintain damaged cement concrete roads and bridges and achieve or surpass the intensity of the original cement concrete, and strengthen the cohesive force between the epoxy-modified unsaturated resin concrete and the roads and the bridges. Besides, the invention is characterized by simple operation, time and labor saving when in maintenance, high efficiency and low cost and being propitious to reduce the hidden danger of vehicles. The invention is solidified after being stirred for 1-2 hours and achieves or surpasses the intensity of the original cement concrete.

Description

technical field [0001] The invention relates to an epoxy-modified unsaturated resin concrete used for roads and bridges. Background technique [0002] Cement concrete is the main material used in road and bridge structures. After a period of use, cement concrete will naturally be damaged, but it is troublesome to repair. If it is not repaired and continues to be used, it will cause more damage to the cement concrete, and even Damage to roads and bridges. Thereby affecting the safety of vehicles on the road, causing traffic accidents. In the past, the maintenance method after the damage of cement concrete was found was to first seal the traffic part of the damaged part of the cement concrete on the road, then cut the damaged part of the cement concrete neatly with a slotting machine, and then use a jack machine to cut the damaged part of the cement concrete Chisel off, and finally use the well-mixed cement concrete to pour into the damaged part of the cement concrete, and w...
