Corrosion-resistant sealing wax for bridge cables and anchor heads and preparation method thereof

Abstract

The invention discloses anticorrosion sealing wax for bridge cables and anchor heads. The anticorrosion sealing wax is a mixture composed of, by weight, 15-40 parts of microcrystalline wax, 8-30 parts of oxidized polyethylene wax, 10-30 parts of oxidized microcrystalline wax, 3-8 parts of rice bran wax, 10-30 parts of naphthenic oil, 8-20 parts of composite antirust agent, 3-15 parts of thickening agent, 0.5-1 part of dispersing agent, 0.5-3 parts of high temperature resistance oxidizing agent and 0.5-1 part of inorganic filler. According to a preparation method of the anticorrosion sealing wax, all the components are sequentially put in a heating container, a certain temperature is maintained, stirring is performed, and then the anticorrosion sealing wax is prepared. The anticorrosion sealing wax for the bridge cables and anchor heads has the advantages of being high in compactness and sealing performance, low in shrinking rate, high in adhesive force, free of losses, high in dampness and heat resistance, salt mist resistance and oxidation resistance and long in anticorrosion period, and has long-term protective properties on the bridge cables and anchor heads and other steel components.

Description

technical field [0001] The invention relates to an anti-corrosion sealing material and a preparation method thereof, in particular to an anti-corrosion sealing wax suitable for anticorrosion of bridge cables and anchor heads and a preparation method thereof. Background technique [0002] At present, in order to solve the problem of steel strand corrosion, the industry mainly pours anti-corrosion grease or anti-rust wax into the anchor head, but there are certain problems in this kind of products in the domestic market; when using anti-corrosion grease to pour the cable anchor head, Due to the high viscosity and low fluidity of the anti-corrosion oil, it is difficult to carry out construction, and there is a phenomenon of "leak irrigation" in the cable pipeline, forming a large number of voids; in addition, the stability of the anti-corrosion oil is not good, and it is easy to separate oil and emulsify , can not play the expected protective effect; [0003] For antirust wax,...

Problems solved by technology

[0002] At present, in order to solve the problem of steel strand corrosion, the industry mainly pours anti-corrosion grease or anti-rust wax into the anchor head, but there are certain problems in this kind of products in the domestic market; when using anti-corrosion grease to pour the cable anchor head, Due to the high viscosity and low fluidity of the anti-corrosion oil, it is difficult to carry out construction, and there is a phenomenon of "leak irrigation" in the cable pipeline, forming a large number of voids; in addition, the stability of the anti-corrosion oil is not good, and it is easy to separate oil and emulsify , can not play the expected protective effect;

[0003] For antirust wax, although there is no problem of poor fluidity in pouring construction, most of the antirust waxes on the market are used for ordinary steel or automobile antirust. This type of wax is used in bridge cables, anchors, etc. On the head, there are certain problems, such as the shrinkage rate is too large, it is easy to shrink and sag during the cooling process, and it must be filled twice to be completely filled; during the cable vibration process, the wax is too hard or has poor adhesion. It is easy to make it separate from the steel strand, form a hole in the center of the cable, and even cause the wax to crack

These problems make the steel strands directly exposed to the atmospheric environment, and cannot effectively play the role of wax corrosion protection.
