Non-toxic environment protective solvent type bridge floor water-proofing material and preparation thereof

Abstract

The invention provides an innoxious environment-friendly solvent waterproof material of bridge floor, which can be painted on clean and dry cement bridge floors by a special painting spraying equipment in a certain of dosage and a layer of waterproof film with compact structure can be formed after nature solidification. The heat asphalt mix can be directly coated on the bridge floors and the work can be finished after rolling by a common road roller. The innoxious environment-friendly solvent waterproof material of bridge floor has the advantages of strong adhesiveness, good waterproof performance as well as good high temperature property and good low temperature property.

Description

1. Technical field [0001] The invention belongs to the field of waterproof materials, and particularly relates to a solvent-based bridge deck waterproof material and a preparation method thereof. 2. Background technology [0002] Existing technology: With the development of highways in my country, the number of highway bridges is also increasing. At present, the bridge deck pavement has been gradually transformed from cement concrete bridges to composite pavement. Therefore, the problem of composite bridge deck pavement has caused domestic counterparts. wide attention. Many studies and engineering practices at home and abroad have shown that composite bridge deck pavement has good driving comfort and continuity, and has gradually become the mainstream of bridge deck pavement development today and in the future. According to the use conditions of bridge deck pavement, how to improve the interlayer waterproof performance, adhesion performance and shear resistance of bridge dec...

AI Technical Summary

Problems solved by technology

Through research and analysis, the main problems of bridge waterproofing are as follows: first, bridge design problems, mainly manifested in problems caused by unreasonable pavement design, failure of waterproofing treatment at weak points of stress, and unreasonable waterproof design of bridge structures; second, waterproofing The material problem is mainly the lack of special waterproof materials for bridges; the third is that in the construction process, the quality of waterproof construction has not yet formed a unified operating procedure and acceptance standard, and there is a lack of professional waterproof construction teams for bridge projects

However, in practical engineering applications, this waterproof membrane is difficult to fit tightly with the uneven bridge deck, and there are large construction defects, and it is easy to be punctured locally during the construction process.

These defects have seriously affected its waterproof effect and bonding effect, so it is not widely used.
