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.

Technical field
The present invention relates to a kind of water-fast cable fire-proof groove box that do not fire; And water-fast manufacture method of not firing cable fire-proof groove box; Product of the present invention is applicable in the place of various adverse circumstances such as the intensive place of cable, wet environment, cable tunnel and uses, have water-fast, do not fire, the advantage of the electromagnetic radiation of anticorrosion, the shielding external world and control cable itself.
Background technology
At present, the cable tray that manufacturing is produced on the market, its type is respectively: polymethyl methacrylate steel tank box, inorganic fire-resistant groove box, metallic channel box, perspex steel and metal composite groove box etc.Various materials respectively have advantage, also have many deficiencies, with moist local, are prone to rust like the metallic channel box, and it is fast, yielding to conduct heat during burning.Organic type of groove box belongs to flame retardant type or burnable, and flameproof effect is limited, uses not have in Combustible Place and do not fire effect.Inorganic fire-resistant groove box only is applicable to the cable fire-proof of dry environment, and is not suitable for the cable fire-proof of wet environment.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of water-fast cable fire-proof groove box and preparation method thereof that do not fire.
The technical scheme that the present invention adopts realizes in the following manner:
A kind of water-fast cable fire-proof groove box that do not fire mainly is made up of groove lid plate, pallet two parts.
Further, be provided with screen in groove lid plate and the pallet, the surface is provided with thin layer.
Further, screen is a wire netting.
Further, groove lid plate and pallet are the composite fireproof heat-barrier material.
The inboard of groove lid plate and pallet is watertight composition, and the outside is fireprotection layer.
Water-fast preparation method of not firing cable fire-proof groove box, wherein, the first step, the magnesia composite mortar stirs in proportion; Thickness is provided with one deck clay layer and one deck glass on request, is provided with cloth intershield layer between clay layer and glass, is squeezed into sheet profile; Second step, the entering mold cured reaction back demoulding, the product after the 3rd step, the demoulding carries out trimming, punches, is trimmed to acceptance(check), wherein; During curing, adopt the double-layer films clad can to handle, guarantee that product appearance is smooth, bright and clean; Curing reaction temperature is that 18 ℃-25 ℃, humidity are 50%-80%, curing reaction at least 12 hours, and the component of its clay layer and weight proportion are:
Magnesia: 34%-36%
