Problems solved by technology

[0003] The current strain clamps are used for the connection of corners, splices and terminals, so the strain clamps have to bear a relatively large force, and the strength of the existing strain clamps cannot meet the demand, resulting in short service life, which still needs to be solved. improve

Abstract

The invention relates to the field of wire clamps, and discloses a high-strength strain clamp and a processing technology thereof. The high-strength strain clamp comprises a clamp body, the clamp bodyis treated by a surface treating agent, and the surface treating agent is prepared from the following raw materials in parts by weight: 30-40 parts of urea-formaldehyde resin, 5-8 parts of polycarbonate, 4-5 parts of propylene glycol methyl ether acetate, 2-3 parts of nano zinc oxide, 1-2 parts of a cross-linking agent and 20-30 parts of a solvent. The high-strength strain clamp and the processing technology thereof have the following advantages and effects: the urea-formaldehyde resin is cross-linked with a mixture of the polycarbonate and the propylene glycol methyl ether acetate, and thenthe nano zinc oxide is added, so that on the one hand, the dispersity after mixing of the components is improved, cross-linking sites are increased, the nano zinc oxide is uniformly dispersed, and thus the strength is improved; and on the other hand, after the components are mixed, the fluidity is good during heating melting, a formed coating is of a microporous structure, when the coating is sprayed on the clamp body, the coating is firmly combined with the clamp body and has good adsorbability, and therefore the strength of the clamp body is stably improved.

Description

technical field [0001] The invention relates to the technical field of wire clamps, in particular to a high-strength tension-resistant wire clamp and its processing technology. Background technique [0002] Iron or aluminum metal accessories widely used in fittings and transmission lines are collectively referred to as fittings. Most fittings need to bear large tension during operation, and some of them must also ensure good electrical contact at the same time; strain clamps are used for Fix the wires to withstand the tension of the wires, and hang the wires to the fittings on the tension strings or towers. [0003] The current strain clamps are used for the connection of corners, splices and terminals, so the strain clamps have to bear a relatively large force, and the strength of the existing strain clamps cannot meet the demand, resulting in short service life, which still needs to be solved. improve. Contents of the invention [0004] Aiming at the deficiencies in th...
