Fire-proof, non-combustible, anti-corrosion and environment-friendly cable tray box and its production process

Abstract

The invention discloses a fire-proof, noncombustible, anti-corrosion and environment-friendly cable tray box. The cable tray box is produced from a plate material adopting the structure as follows: the plate material comprises an inorganic core material, an organic material layer wrapping the inorganic core material, and a bonding layer positioned between the inorganic core material and the organic material layer, wherein the bonding layer mainly comprises acrylate waterproof coating and polyvinyl chloride waterproof coating according to a weight ratio of 1:(1-1.5); the plate material furthercomprises a structural layer distributed inside the inorganic core material and inside the organic material layer, and a gel coat layer arranged outside the organic material layer; the structural layer is made of alkali-free glass fiber cloth; the gel coat layer uses gel coat resin. The cable tray box produced according to the technical scheme adopted by the invention has the excellent performanceof fire prevention, noncombustibility and strong anticorrosion, the using performance of the cable tray box is significantly improved, and the service life thereof is prolonged; by a production technology of the cable tray box, production operation is simple, an obtained cable tray box product is excellent in performance and an advantage of environment friendliness is achieved.

Description

Technical field [0001] The invention relates to the technical field of cable trough boxes, in particular to a fire-proof, non-combustible, corrosion-resistant and environmentally friendly cable trough box, and a production process for the cable trough box. Background technique [0002] Cable trough box is a trough box used to place cables in a fire protection system. Because cables are flammable products, fires of cables caused by spontaneous ignition of cables or other reasons occur from time to time, and the conductivity of cables will cause fire It spreads to every corner quickly and causes a wide range of hazards. The use of fire-resistant cable trays can effectively reduce the incidence of fire, control the spread of fire, and reduce fire damage. [0003] For a long time, steel cable trays or cement cable trays are often used for cable trays, but these two types of cable trays have many defects. For example, steel cable trays have high strength, but their production costs are ...

AI Technical Summary

Problems solved by technology

[0003] For a long time, cable troughs have often been made of steel or cement, but these two cable troughs have many defects. phenomenon, and after 3 to 5 years of use, the surface will appear rust to varying degrees. At the same time, steel cable troughs do not have antistatic capabilities; cement cable troughs have low strength, high water absorption, and are prone to biological growth. The total amount of monomers is large. , transportation and installation are inconvenient; other material cable troughs, such as magnesite composite materials, pultruded thermosetting composite materials, etc., also have defects in use, which cannot meet the needs of cable troughs when they are used. Stable performance, high fire resistance, high strength, and durability Good performance, easy installation and other comprehensive performance

In addition, in order to improve the performance of the fire-resistant grade of the cable trough box, the cable trough box produced by plates made of metal skeleton and glass fiber reinforced materials, inorganic materials, refractory aluminum silicate wool felt, and fireproof-based foaming paint have been successively developed. However, due to the emphasis on fire protection and heat insulation performance, the heat of the cable is not easy to dissipate, and the problem of accelerated aging of the cable occurs.
