Abstract

The invention relates to an epoxy resin system for producing telegraph poles and a preparation method of the epoxy resin system. The epoxy resin system comprises a component A and a component B. The component A comprises 25-50% of bisphenol-A epoxy resin, 3-25% of hydantoin epoxy resin, 20-40% of flame-retardant additives, 10-25% of slow-release agents and 1-3% of functional assistants. The component B comprises 90-97% of curing agents, 1-5% of accelerants and 1-5% of assistants. The epoxy resin system has high heat insulation performance and excellent mechanical property, especially excellent bending performance, has enough flame retardance, and has high wettability to facilitate filament winding; gel reaction can be achieved quickly at the high temperature, and accordingly, production efficiency is improved; the epoxy resin system does not release harmful gases in the production process, thereby being beneficial to environment protection.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to an epoxy resin system for preparing utility poles and a preparation method thereof. Background technique [0002] As one of the infrastructures for wired electricity transportation, utility poles need to ensure the stability of their use to avoid unnecessary losses in harsh environments. Nowadays, due to harsh natural conditions such as strong wind and severe cold in many areas, the traditional wood, steel and cement utility poles have been damaged. In contrast, the utility poles made of fiberglass have withstood the test. FRP poles have advantages that traditional material poles do not have. They have higher strength and durability. The poles have an expected lifespan of 125 years in most climates and are designed for a minimum life of 65 years in the worst climates. This is not only cost-effective, but also beneficial to the reliability and safety of the country's...
