preparation example Construction

[0056] The preparation method of the direct yarn sizing agent for insulators comprises the following steps:

[0057] 1S: Add 40% to 50% of the total amount of water in the container, and then add the pH adjuster. After stirring for 3 to 5 minutes, add the first coupling agent; after stirring for 30 to 40 minutes, add the second coupling agent. Second coupling agent; continue to stir for 30-40 minutes until the first coupling agent and the second coupling agent are dispersed evenly;

[0058] 2S: Dissolve lubricant, antistatic agent and surfactant in 5 to 10 times the amount of water at 40 to 50°C, stir and dilute, then add to the container;

[0059] 3S: Dilute the film-forming agent with 1.5 to 2 times the amount of water and add it to the container;

[0060] 4S: Add the pH adjuster to the container again and stir to adjust the pH range.

Embodiment

[0062] The components of the wetting agent used in the embodiments of the present invention are as follows:

[0063] Coupling agent: 3-glycidyl etheroxypropyl trimethoxysilane coupling agent, the product brand is A-187; γ-aminopropyl trimethoxysilane, the product brand is A-1100;

[0064] The lubricant uses PEGMO;

[0065] The antistatic agent uses polyoxyethylene fatty quaternary ammonium salt;

[0066] Film-forming agent: bisphenol A type epoxy resin emulsion, product brand is Neoxil 965 (manufacturer: Netherlands DSM company); bisphenol F type epoxy resin emulsion, product brand is Neoxil 962 / D (manufacturer: Netherlands DSM company) );

[0067] The non-ionic surfactant adopts alkylphenol polyoxyethylene ether OP;

[0068] The pH regulator uses acetic acid.

Abstract

The invention provides a direct yarn impregnating compound for an insulator. According to the impregnating compound, the percentage of solid mass of each component in solid mass of the impregnating compound is as follows: 10 to 20 percent of a coupling agent, 3 to 10 percent of lubricant, 2 to 9 percent of antistatic agent, 55 to 78 percent of film forming agent, 0.5 to 6 percent of surfactant and3 to 10 percent of pH (Potential of Hydrogen) value regulator; the film forming agent is prepared from a first film forming agent and a second film forming agent; the first film forming agent is selected from one of water-soluble epoxy resin emulsion, bisphenol A type epoxy resin emulsion and bisphenol F type epoxy resin emulsion; the second film forming agent adopts the bisphenol F type epoxy resin emulsion; the mass ratio of the two film forming agents ranges from (1 to 4) to (1 to 0.6). Direct yarns produced by the impregnating compound have good compatibility and impregnation with targetresin, i.e., epoxy resin; a product has high mechanical properties and good electrical insulating performance, and requirements of standards are met.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced thermosetting resins, in particular to a direct yarn sizing agent for insulators and a preparation method and application thereof. Background technique [0002] With the expansion of the national grid, high-voltage and ultra-high-voltage power transmission has become the mainstream technology of power transmission, and the demand for hollow composite insulators for power transformation equipment produced by glass fiber is also increasing. Compared with porcelain hollow insulators, composite hollow insulators have the advantages of light weight, good explosion-proof performance, stable mechanical performance, excellent anti-pollution flashover performance, and convenient installation, transportation and maintenance. At present, it has been widely used in bushing GIS fully enclosed combined electrical appliances, vacuum circuit breakers, current transformers and other equipment; its o...
