Problems solved by technology

In order to solve this problem, chemicals such as epoxy resin and asphalt have been used to fill the gaps, or the paint is pre-coated on the surface of the steel plate in contact with the cement, but the former cannot avoid the corrosion of the steel plate by the cement before curing, and the filling of chemicals itself decomposes over time
The latter (paint) has a short lifespan and will still separate from the steel plate to form gaps after the cement has cured

Embodiment 1

[0015] An interface binder between steel and concrete, its composition percentage is:

[0016] Name

[0017] Put the above components into a cone mixer in turn, mix for one hour and then grind to 400 mesh in a ball mill to obtain the product interface binder. When it is bonded to the steel plate and cement board, the bonding fastness is measured as 22 megapoise.

Embodiment 2

[0019] An interface binder between steel and concrete, its composition percentage is:

[0020] Name

[0021] Put the above components into a cone mixer in turn, mix for one hour and grind it to 500 mesh in a ball mill, add water according to 1:1 and mix evenly and brush on the steel plate, then grouting ordinary cement on the steel plate, and curing for 27 days. After breaking the cement with a steel hammer, the interface adhesive still adheres to the steel plate.

Embodiment 3

[0023] An interface binder between steel and concrete, its composition percentage is:

[0024] Name

[0025] Put the above components into a cone mixer in turn, mix for one hour and grind to 400 mesh in a ball mill, add water in the same amount and mix thoroughly, when iron red appears. This time it is suitable for the requirements when the cement color needs to be adapted. It needs to be replaced with other color powders instead of iron oxide red powder, and its bonding strength is 18 megapoise.

Abstract

An interface binder used for steel and concrete is composed of modified styrene acrylic emulsion powder, composite barium aluminate, composite iron titanium powder and an assistant. The interface binder is produced by mixing the above components, and carrying out ball milling of the components. The interface binder used between a steel plate and cement makes the steel plate and the cement bonded, no slits generated permanently and the steel plate contacting with the cement not corroded. The interface binder has the advantages of simple production, use convenience, no toxicity or pollution, one-time construction, and permanent effect.

Description

Technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a steel-concrete interface binder and a production method. Background technique [0002] As we all know, steel and cement do not adhere to each other, that is, cement cannot adhere to the surface of steel. In large bridge constructions, there are many contact surfaces between steel and cement. Because of the strong alkalinity of the cement, the steel plate is corroded strongly before the cement is solidified. When the cement is solidified, it separates from the steel plate and forms a gap. Air and rain After entering the gap, the corrosion of the steel plate is accelerated and aggravated. To solve this problem, chemicals such as epoxy resin, asphalt, etc. have been used to fill the gap, or the paint has been pre-coated on the surface of the steel plate in contact with the cement, but the former cannot avoid the corrosion of the steel plate before the cement is cured, and...
