Description

Socket casting agent

Technical Field

The invention relates to the technical field of hoisting equipment, in particular to a steel wire rope socket casting agent.

Background

Wire rope joints are usually cast using metal (e.g. zinc) or resin glues, but each has disadvantages: although the strength of the cast metal is high after the cast metal is formed, the melting point of the metal for casting is high, for example, the melting point of zinc is about 420 ℃, so that the requirement on casting equipment and environment is high, and the cast metal is not suitable for on-site casting; although normal-temperature operation can be realized by adopting resin glue for casting, and the requirements on personnel and equipment are lower, the mechanical property is not high after the resin glue is cured and formed, the properties are brittle, the cable joint is easy to crack when being subjected to impact load, and the reliability is insufficient.

In summary, how to provide a soxhlet casting agent with high mechanical properties and normal temperature operability is a problem to be solved by those skilled in the art.

In view of the above, the invention aims to provide a socket casting agent, which can realize on-site casting at normal temperature, and has good mechanical properties, strong binding force with a wire rope and high reliability after curing and forming.

In order to achieve the above purpose, the invention provides the following technical scheme:

a soxhlet casting agent comprises a liquid component and a solid component. Wherein the liquid component comprises unsaturated polyester resin, diluent and accelerator; the solid component includes a powder reinforcement and an initiator.

In the liquid component, the raw materials in parts by mass are as follows: 100 parts of unsaturated polyester, 5 to 50 parts of diluent and 0.1 to 2 parts of accelerator.

In the solid component, the raw materials in parts by mass are as follows: 100 parts of powder reinforcement and 0.5 to 5 parts of initiator.

Optionally, in the liquid component, the diluent is styrene; the promoter is one or the combination of dimethyl p-toluidine, dimethylaniline and diethylaniline.

Optionally, in the solid component, the powder reinforcement is one or a combination of metal powder, mineral powder and ceramic powder; the initiator is benzoyl peroxide.

Optionally, in the soxhlet casting agent of the present invention, the liquid component is used in an amount of 100 parts, and the solid component is used in an amount of 100 to 300 parts.
