Abstract

The invention relates to a ceramic repairing material. The ceramic repairing material is a dual-component adhesive prepared from 24-28wt% of K resin (PB-5925), 16-22wt% of K resin (PB-5910), 12-18wt% of K resin (KR01), 12-16wt% of K resin (KR03), 19-29wt% of 300mesh pure iron powder, 13-18wt% of ultrafine silica, 0.1-0.3wt% of a silane coupling agent, 2-6wt% of 300mesh amorphous titanium powder, 3-9wt% of imidazole, and 5-13wt% of a diluent; and a group A is a base material, a group B is a solidification agent, and the group A is mixed with the group B according to a ratio of 1:1. The ceramic repairing material can rapidly solidify at normal temperature, and can reach rated hardness and toughness; and the solidification speed is controllable and can be conveniently adjusted, so the ceramic repairing material is very suitable for onsite repairing, and can greatly meet practical production needs.

Description

A kind of ceramic patching material

Technical field

The present invention relates to a kind of ceramic patching material, belong to Material Field.

Technical background

It is phenomenon common in production unit that piping failure leaks.

The restorative procedure such as built-up welding, repair welding, cold welding of current employing; the requirement of reparation can be reached; but these methods and material have a common shortcoming, being exactly the use that all must stop pipeline, keeping in repair when shutting down; but; field working conditions is complicated, in a lot of situation, pipeline after stopping using again pipe-repairing be very difficult; therefore, pipe-repairing in non-stop-machine situation is met in the urgent need to new materials and methods.

Summary of the invention

The technical issues that need to address of the present invention there is provided a kind of ceramic patching material, are intended to solve pipe-repairing in non-stop-machine situation.

In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:

A kind of ceramic patching material, the two component adhesive that its weight percent is K resin (PB-5925) 24-28%, K resin (PB-5910) 16-22%, K resin (KR01) 12-18%, K resin (KR03) 12-16%, 300 order straight iron powder 19-29%, superfine silicon dioxide 13-18%, silane coupling agent 0.1-0.3%, 300 order amorphous titanium valve 2-6%, imidazoles 3-9%, thinner 5-13% industrial chemicals are made: expect based on A group, B group is solidifying agent, and blending ratio is one to one.

The ceramic patching material using the present invention to produce presents plastic pug state at normal temperatures, and plasticity and cohesive force by force, are beneficial to reparation operation; Heat can add rapid hardening, and can together with pipeline material strong bond, welding effective in pipeline under realizing normal temperature, and meanwhile, the ceramic patching material after solidification, acid-fast alkali-proof heatproof, can extend the work-ing life of original pipeline greatly.

The ceramic patching material that the present invention uses, every physical and chemical index performance sees the following form:

Project	Index
		Density, g/cm ³	2.8
Softening temperature, DEG C	110
		Shearing resistance, MPa	28
Tensile strength, MPa	85

Compared with existing ceramic patching material, beneficial effect of the present invention is: this ceramic patching material can fast setting at normal temperatures, and reaches specified hardness and toughness; Curing speed is controlled, and convenient adjustment, is very applicable to field patch, greatly can meets needs of production.

Embodiment

Below in conjunction with embodiment, the present invention is described in further detail:

Ceramic patching material of the present invention, its weight percent is the industrial chemicals of K resin (PB-5925) 24-28%, K resin (PB-5910) 16-22%, K resin (KR01) 12-18%, K resin (KR03) 12-16%, 300 order straight iron powder 19-29%, superfine silicon dioxide 13-18%, silane coupling agent 0.1-0.3%, 300 order amorphous titanium valve 2-6%, imidazoles 3-9%, thinner 5-13%;

Embodiment 1

By K resin (PB-5925) or K resin (PB-5910), 300 order straight iron powders, superfine silicon dioxide, silane coupling agent, 300 order amorphous titanium valves, thinner is by more deployed, be fed in vacuum mixer, vacuum stirring 36 hours, makes component A basestocks.

Embodiment 2

By K resin (KR01) or K resin (KR03), 300 order straight iron powders, superfine silicon dioxide, silane coupling agent, 300 order amorphous titanium valves, thinner is by more deployed, be fed in vacuum mixer, vacuum stirring 36 hours, makes B component solidifying agent.

Embodiment 3

The component A basestocks made and B component solidifying agent present clay state respectively, fully can mix, in 30 minutes, get final product fast setting during use with hand, and adjustment blending ratio can regulate and control set time, and after solidification, physicals is constant.

The production unit adopted in the present invention is: precise electronic claims, infrared spectrometer, vacuum drying oven, vacuum mixer.

Conclusion:
