Problems solved by technology

[0003] The existing road-use cold welding agent has problems such as low bond strength and easy aging during use. When construction is carried out in cold weather, the cooling speed of the road-use welding agent is too fast to meet the construction requirements. In order to To improve the sealing and caulking effect of existing cracks on roads and building surfaces, and to improve the defects of easy cracking and low strength of existing caulking agents, for this reason, we propose a cold welding agent for construction roads and its preparation method to solve the above problems

Abstract

The invention discloses a cold welding seam agent for a building road and a preparation method thereof, and relates to the technical field of preparation of constructional engineering. The modified asphalt is prepared from the following components in parts by weight: 10-12 parts of CoO.Co2O3, 10-20 parts of an organic solvent, 6-8 parts of a flocculating agent, 3-8 parts of a stabilizer, 10-20 parts of chlorinated paraffin, 50-70 parts of matrix asphalt, 0.5-1 part of a cross-linking agent, 8-10 parts of an emulsifier, 10-15 parts of 2-ethyl-4-methylimidazole, 15-20 parts of fibers and 50-60 parts of water. According to the cold welding seam agent for the building road and the preparation method, the matrix asphalt and the chlorinated paraffin are added, so that the overall performance ofthe cold welding seam agent is improved; by adding the fiber, the mechanical property is improved, and the prepared cold welding seam agent has good sliding performance and is easy to construct; by adding the organic solvent, CoO.Co2O3, flocculant, stabilizer, cross-linking agent and 2-ethyl-4-methylimidazole for sufficient emulsification, the cold welding seam agent has the advantages of higher bonding strength, excellent elongation, higher wear resistance, longer service life, favorable embeddability and favorable durability.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a cold welding agent for building roads, and also relates to a preparation method of the cold welding agent for building roads. Background technique [0002] With the development of social economy, various cracks will appear in different degrees after the road surface is built. The appearance of cracks not only damages the continuity and flatness of the road surface, but also easily causes water to erode the roadbed and affect the use of the road surface. service life, while increasing the maintenance work and cost of the pavement. The cold weld joint agent for road is a modern pavement engineering material that is not only suitable for quick repair of cracks in asphalt pavement, but also suitable for repair of cracks in cement pavement and filling of expansion joints. Construction in cooler temperatures and rapid opening to traffic play an important role in buil...
