High polymer water stopping material for crack repair and preparation method thereof

Abstract

The invention belongs to the technical field of road maintenance materials, and particularly relates to a high polymer water stopping material for crack repair and a preparation method thereof. The high polymer water stopping material has excellent characteristics like good bonding performance, high water absorbability, high fluidity, short coagulation time, high impermeability, high seasonal adjustability, high durability and simplicity and convenience in construction operation. The high polymer water stopping material comprises, by weight, 10-30 parts of vinyl monomer, 20-60 parts of cementbase material, 10-30 parts of moisturizing agent, 1-2 parts of initiator, 1-2 parts of co-initiator, 1-10 parts of crosslinking agent and 1-2 parts of water reducer. The high polymer water stopping material is prepared through a certain preparation method.

Description

technical field [0001] The invention belongs to the technical field of road maintenance materials, and in particular relates to a high-polymer water-resisting water-stopping material for repairing cracks and a preparation method thereof, in particular to cracks, kerfs, asphalt concrete pavements, and road bridges used in cement concrete pavements crack repair works. Background technique [0002] Cement concrete pavement is one of the most widely used pavement in highway engineering. In actual use, due to reasons such as poor concrete quality, improper construction, climate, hydration reaction of cement, dry shrinkage of cement concrete, and temperature stress, the diseases caused by cracks and slits on the cement concrete pavement affect the service life of the pavement. main reason. [0003] Asphalt concrete pavement is another pavement most widely used in highway engineering. In actual use, transverse cracks are caused by foundation and foundation settlement differences...

Problems solved by technology

[0006] In the prior art, Chinese patent CN108424087A mentions a geopolymer-based cement pavement crack rapid repair material. The most prominent advantage is high strength, but its raw material process is complex and difficult to operate, and the main raw material is an inorganic binder. It does not have flexibility; and the production of powder generally requires simple process, easy to obtain raw materials, and crack glue has a certain degree of flexibility

[0007] Acrylic repair materials have the advantages of low viscosity and fast curing time, but they are generally polymerized organic polymer materials, suitable for asphalt pavement, not conducive to environmental protection and cracks in cement pavement, and have the problems of large volume shrinkage and short aging time
