High-strength antistatic, aging-resistant, environmentally-friendly and flame-retardant cable tray, and making method thereof

Abstract

The invention discloses a high-strength antistatic, aging-resistant, environmentally-friendly and flame-retardant cable tray. The cable tray comprises, by weight, 80-100 parts of PVC resin, 30-50 parts of glass fibers, 25-35 parts of polyolefin elastomer, 20-30 parts of waste plastics, 2-5 parts of antimony trioxide, 6-8 parts of a barium-zinc stabilizer, 8-12 parts of a flame retardant, 7-11 parts of a coupling agent, 3-5 parts of an antistatic agent, 10-15 parts of a processing assistant, 2.5-3.5 parts of zinc stearate, 4-10 parts of aluminum hydroxide and 2.5-3.5 parts of titanium dioxide. The cable tray has the advantages of high bending strength, high bearing capacity, excellent antistatic and flame-retardant properties, excellent acid, alkali and salt resistance, long service life, low cost, energy saving, environmental protection and no pollution, and can be widely applied to the fields of petroleum, chemical engineering, light industry, televisions and telecommunication; and a making method of the cable tray has the advantages of low cost of materials, easily available raw materials, concise process, high practical values and good application prospect.

Description

technical field [0001] The invention relates to the technical field of cable bridges, in particular to a high-strength anti-static, aging-resistant, environment-friendly, flame-retardant cable bridge and a preparation method thereof. Background technique [0002] In today's society, the development of the world economy presents a trend of high-speed diversity. The rapid exchange of information makes the connection between various countries and regions increasingly close. As an important link in information transmission, cables play an irreplaceable role. The cable bridge installation and cable laying in the bridge are very important to the whole cable construction process. The selection of the appropriate cable bridge and cable laying method is closely related to the cable transmission project and its service life. Cable trays are usually composed of trays, bends, components, hangers, etc. to form a rigid structural system to support cables. It is an installation channel use...

AI Technical Summary

Problems solved by technology

Ordinary A3 galvanized (plastic-sprayed) pallets have low cost and simple production process, but they have poor corrosion resistance, are easy to oxidize and rust, and have a short service life. Stainless steel pallets have beautiful appearance, long service life and good anti-corrosion performance, but their cost is high. The coefficient is high, and the cable will be damaged in case of fire; the aluminum alloy tray has beautiful appearance and light weight, but has disadvantages such as low strength, small bearing capacity, high cost, easy oxidation of the surface, and high thermal conductivity.

At present, the raw materials of cable bridges are gradually eliminating steel products and using plastic products. The traditional formula has a large amount of addition, the effect is poor, the production cost is high, and the product fails to achieve the expected effect of use. Due to the high-strength hard plastic cable bridge produced by us, its Some of them are used outdoors, and must withstand the sun and rain, and adapt to the requirements of corrosive environments.
