Embodiment 1

[0023] Embodiment one, by figure 1 It can be seen that the water-resistant and non-combustible cable fireproof tank box is mainly composed of two parts: the tank box cover plate 1 and the tray 2, and is formed by an extrusion production line mechanism. Put it in the barrel of the extrusion production line equipment, cover a layer of glass fiber cloth with a layer of cement, set a metal mesh shielding layer 3 between the cement layer and glass fiber cloth, start extrusion production, and extrude composite molding materials , Put the extruded material into the mold, cover the material in the mold with two layers of film, and cure it into the tank box cover plate 1 and the tray 2. The reaction is controlled at a temperature of 20°C and a humidity of 70%. The curing reaction can be demoulded within 12 hours. After demoulding, the product is removed, punched, and trimmed until it passes the acceptance test. The inner side of the tank box cover plate 1 and the tray 2 are all waterp...

Embodiment 2

[0024] Embodiment 2, the manufacturing process is the same as Embodiment 1, but the weight ratio of the components of the cement is: magnesium oxide: 36%; magnesium chloride: 21%; talcum powder: 12%; perlite: 4%; saw foam: 5.2%; Modifier: 2.3%; phosphoric acid: 0.07%; waterproof powder: 19.43%.

Embodiment 3

[0025] Embodiment 3, the manufacturing process is the same as Embodiment 1, but the weight ratio of the components of the cement layer is: magnesium oxide: 35%; magnesium chloride: 22%; talcum powder: 13%; perlite: 4.44%; saw foam: 4% ; Modifier: 2.3%; Phosphoric acid: 0.04%; Waterproof powder: 19.22%.

Abstract

The invention discloses a waterproof non-inflammable cable fireproof groove box and a manufacturing method thereof. The waterproof non-inflammable cable fireproof groove box comprises a groove box cover plate, a tray and a connecting plate. The waterproof non-inflammable cable fireproof groove box is manufactured by using raw materials including magnesium oxide, magnesium chloride, running water, glass cloth, phosphoric acid, an aqueous solution agent, waterproof powder, a metal net and a modifier through the following steps of: firstly, preparing the concentration of chlorine water according to a certain proportion, adding a certain quantity of chlorine water into an agitator, then adding additives, and preparing and blending the magnesium oxide to form slurry or paste daub; then placing the slurry or paste daub of the magnesium oxide into an equipment hopper on an extrusion production line; adding shielding layers in a way that one layer of the daub and one layer of glass cloth are alternately arranged; starting to extrude a composite molding plate; when the composite molding plate enters into a mould, carrying out two-layer film treatment, demolding after a curing reaction; trimming, punching, finishing the product subjected to the demolding until checking to be qualified. The product provided by the invention is suitable for being used in various places with severe envelopments, such as places with intensive cables, humid environments, cable tunnels and the like and has the advantages of waterproofness, non-inflammability, corrosion resistance, isolation from the outside and control of electromagnetic radiation of the cable.

Description

technical field [0001] The invention relates to a water-resistant and non-combustible cable fire-proof trough and a method for making the water-resistant and non-combustible cable fire-proof trough. The product of the invention is suitable for use in various harsh environments such as cable-intensive places, humid environments, and cable tunnels. It has the advantages of water resistance, non-combustibility, corrosion resistance, shielding the outside world and controlling the electromagnetic radiation of the cable itself. Background technique [0002] At present, the types of cable trough boxes manufactured and produced on the market are: plexiglass steel trough box, inorganic refractory trough box, metal trough box, plexiglass steel and metal composite trough box, etc. Various materials have their own advantages, but there are also many disadvantages, such as metal slot boxes used in humid places, easy to rust, fast heat transfer when burning, and easy to deform. Organic ...
