Alloy plastic composite cable bridge and preparation method thereof

Abstract

The invention discloses an alloy plastic composite cable bridge, which comprises the following raw materials by weight: 45-55 parts of PVC, 10-20 parts of ABS, 3-10 parts of a corrosion-resistant dielectric agent, 5-15 parts of calcium borosilicate glass powder, 3-7 parts of modified pearlescent mica powder and 20-30 parts of composite spraying powder. According to the invention, PVC and ABS are adopted as base materials; the added raw materials not only can reach an acid and alkali resistant effect, but also can avoid the corrosion problem brought about by electrolysis, the corrosion-resistant dielectric agent is prepared from a dielectric raw material and a corrosion-resistant liquid, the dielectric raw material is formed by combination of high-viscosity silicone oil, silicon dioxide particles and TiC powder, the overall dielectric effect is improved, the added corrosion-resistant liquid is formed by combination of dodecyl glucoside, phenoxyethanol and polydimethylsiloxane, not onlyreaches the acid and base resistant anticorrosion effect, but also can solve the corrosion problem of electrolysis.

Description

technical field [0001] The invention relates to the technical field of cable trays, in particular to an alloy-plastic composite cable tray and a preparation method thereof. Background technique [0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supporting arms and installation accessories. The bridge frame in the building can be erected independently or attached to various buildings and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in the building. An open-air bridge. With the development of my country's economic construction, the application of cable trays is becoming more and more extensive, which makes cables and wires have a standardization and generalization level. [0003] Cable trays are mostly used in corrosion-resistant environ...

AI Technical Summary

Problems solved by technology

[0003] Cable trays are mostly used in corrosion-resistant environments. At the same time, in the process of power transmission, it is easy to cause electrolytic corrosion and accelerate the corrosion rate. Therefore, improving the corrosion resistance of cable trays can significantly increase the service life of cable trays. The existing Chinese patent documents are published No.: CN109261460A discloses a composite corrosion-resistant cable tray and its coating process, which relates to the technical field of cable trays. Carbosilane coating is coated with a thickness of 4-6mm. The anti-corrosion layer includes the following components by weight: epoxy resin: 30-35 parts, hydroxyethyl cellulose: 2-4 parts, pentachloride Phosphorus: 3-5 parts, sodium dehydroacetate: 2-3 parts, 3-pentanediol monoisobutyrate: 1-3 parts, aluminum tripolyphosphate: 2-5 parts, low melting point glass powder D250: 3 -7 parts, calcined pottery clay silicate: 7-9 parts, chromium oxide green: 4-6 parts, dioctyl phthalate: 5-8 parts, potassium dichromate 7-9 parts, although this patent document It can play an anti-corrosion function, but the raw materials such as aluminum tripolyphosphate and potassium double complex acid in the raw materials can improve the electrolytic corrosion of the cable tray, and instead accelerate the corrosion rate
