Problems solved by technology

[0003] Ordinary pultruded FRP cable trays are widely replacing metal cable trays due to their outstanding corrosion resistance. However, because FRP cable trays are non-conductive and easy to burn, the static electricity generated during use often cannot be eliminated. In addition, they do not have resistance Combustion function, it is easy to bring safety hazards

Abstract

The invention discloses an antistatic high-flame-retardancy pultruded fiberglass-reinforced plastic cable bridge and a preparation method thereof. The fiberglass-reinforced plastic cable bridge comprises the following components in parts by weight: 100.0 parts of LJ-101 resin, 1.0-1.5 parts of BPO (benzoyl peroxide), 1.2-1.6 parts of MEKP (methyl ethyl ketone peroxide), 2.5-3.5 parts of zinc stearate, 1.0-1.5 parts of lead stearate, 28.0-35.0 parts of aluminum hydroxide, 2.5-3.5 parts of titanium white, 0.8-1.2 parts of multiwall carbon nanotube, 2.5-4.0 parts of nano Al(OH)3 and 2.5-3.5 parts of halogen-free flame retardant. The preparation method comprises the following steps: after a mold reaches a preset temperature, adding the materials into a glue tank to start production; after the fiberglass yarn and felt enter the die cavity, gelatinating in a first region, curing in a second region and postcuring in a third region to form; and demolding to obtain the formed cable bridge profile. The pultruded fiberglass-reinforced plastic cable bridge has the characteristics of static resistance, high strength and the like, and can widely substitute the traditional cable bridge material.

Description

technical field [0001] The invention relates to a pultruded glass fiber reinforced plastic product and a processing technology, in particular to an antistatic high flame retardant pultruded glass fiber reinforced plastic cable bridge and a preparation method thereof. Background technique [0002] FRP cable tray is composed of glass fiber reinforced plastic, flame retardant and other additives, and is pressed by composite molding material and stainless steel shielding net. Due to the low thermal conductivity of the selected materials and the addition of flame retardants, the FRP cable bridge has the advantages of wide application, high strength, light weight, reasonable structure, low cost, long life, strong corrosion resistance, simple construction, and wiring. Flexible, standard installation, beautiful appearance, etc., can be conveniently used with metal bridges, suitable for indoor and outdoor overhead cable trenches such as power cables with a voltage below 10 kV, contro...
