High-strength bridge deck waterproof adhesive and preparation method thereof

Abstract

The invention discloses a high-strength waterproof deck binder and a preparation method thereof.The binder is made by mixing components A, B and C according to a weight ratio of 1:1:1.5; the component A comprises, according to parts by weight: 100 parts of emulsified asphalt, 60-75 parts of EVA (ethylene-vinyl acetate copolymer), 20-30 parts of hydroxypropyl acrylate, 5-8 parts of hydroxyethyl acrylate, 0.2-2 parts of polytetrafluoroethylene, and 2-7 parts of an amine curing agent; the component B comprises, according to parts by weight: 40-45% of bentonite, 3-4% of starch, 1-3% of special resin, 6-9% of an organic polymer material, and 40-50% of asphalt-cement; the component C is made by mixing the following materials according to percent by weight: 10-40% of white cement, 5-20% of mica powder, 5-20% of ash calcium powder, 5-15% of silica fume powder, 10-40% of quartz sand, 0.1-0.7% of dispersible emulsion powder, 0.1-0.5% of organosilicon powder, 0.1-0.5% of lignin, and 0.1-0.4% of polypropylene fiber; the quartz sand is 20-80 in mesh.

Description

technical field [0001] The invention relates to a preparation method of a bridge deck waterproof material in the field of chemical materials, in particular to a high-strength bridge deck waterproof adhesive and a preparation method thereof. Background technique [0002] At present, the effective service time of road-bridge roads generally fails to reach its design service life, often due to the lack of water stability of the asphalt concrete surface layer, which causes early water damage to the road surface, so that the expressway pavement will be damaged after 2-3 years after it is opened to traffic. There are obvious pits, looseness and other phenomena; for long-span steel bridges, the quality of the bridge deck pavement directly affects the safety, comfort, durability and investment benefits of the bridge, and the social and economic benefits. Wait. [0003] In recent years, the research, production and application of waterproof adhesives worldwide have reached an unprec...

Problems solved by technology

[0004] Therefore, in the prior art, the surface activity of the bridge deck pavement is changed by adding various modifiers to form a waterproof film to play a waterproof role; these waterproof materials not only cannot significantly improve the steel bridge deck and bridge The adhesion between the surface concrete layers, and the waterproof effect cannot last
