Problems solved by technology

This kind of anti-corrosion primer also needs to be constructed as soon as possible after preparation, which requires high construction technology, and the construction technology will directly affect the anti-corrosion effect; at the same time, the strength of the anti-corrosion coating formed after construction is limited, and it is easy to cause damage under the action of mechanical force. Damage, and then breakage, thus affecting the overall anti-corrosion effect

Abstract

The invention provides a compound rubber protective belt for a bridge, a preparation method and an application thereof. The compound rubber protective belt is prepared by calendering chlorosulfonated polyethylene rubber and gridding cloth, wherein the chlorosulfonated polyethylene rubber is prepared by plastifying and mixing 30 to 50 parts of chlorosulfonated polyethylene, 36 to 50 parts of filler, 10 to 12 parts of dioctyl phthalate, 0.5 to 2 parts of pentaerythritol, 0.5 to 2 parts of TRA, 0.1 to 0.3 parts of pigment, 1 to 4 parts of magnesium oxide and 1 to 2 parts of additive. The compound rubber protective belt adopting the gridding cloth as a reinforced skeleton has the advantages that the mechanical strength and the weather resistance are higher; a prefabricated forming mode is adopted, and in the construction process, the welding process and the vulcanizing process are carried out synchronously, so that the construction procedures are reduced, the requirement for the construction technology is lowered and the construction is easier.

Description

technical field [0001] The invention relates to a composite rubber belt in the technical field, in particular to a composite rubber protective belt for bridges. Background technique [0002] The bridge is one of the important infrastructures, and the corrosion of the bridge is one of the most important reasons affecting the service life of the bridge. Referring to the relevant description in the transportation industry standard JT / T 694-2007 "Technical Conditions for Anti-corrosion Coating of Suspension Bridge Main Cable System", traditional bridge cables use polysulfide sealant as the surface anti-corrosion material, which has stable performance and a long history of use. At present, the solution commonly used in bridge cables, however, polysulfide sealant has also exposed its many shortcomings during long-term use, for example: its high-viscosity two-component raw material characteristics make it difficult to be stirred evenly, and the two-component The parts must be used...
