Economic and environment-friendly polymer-based cable bridge

Abstract

The invention discloses an economic and environment-friendly polymer-based cable bridge which comprises the components with the content as follows: 100phr of polyvinyl chloride (PVC), 5phr of Ca-Zn compound stabilizer, 10phr of chlorinated polyethylene (CPE), 3phr of P83, 0.5phr of paraffin wax, 0.3phr of polyethylene (PE) wax, 0.4phr of acrylic acid (ACR), 10phr of calcium carbonate whisker, 8phr of DBDPE, 5phr of nano antimonous oxide, 2phr of compound zinc borate, 5phr of titanium dioxide, 0.5phr of 1010 and 0.2phr of UV-531. The economic and environmentally friendly polymer-based cable bridge breaks through the key technology of strength and water resistance of fire-proof and environment-friendly multi-element composite material, and has the characteristics of being environment-friendly, attractive, light in mass, flame retardant, corrosion-resistant, low in manufacturing cost, convenient in field installation, long in service life and the like, thus being widely applied to industries such as chemical industry, petroleum and the like and being more suitable for being used in the environmental conditions such as dampness, salt mist and chemical gas.

Description

technical field [0001] The invention relates to an economical and environment-friendly polymer-based cable tray, which belongs to the field of new materials. Background technique [0002] Cable bridges have been widely used in high-speed railways, highways and subways and other bridges for wiring. The traditional bridges are made of cement, metal and glass fiber reinforced plastic materials, which cause inconvenience in construction, or high cost, or short service life, or can not be recycled. cause environmental pollution. [0003] At present, there are roughly the following types of cable trays in the market: ordinary A3 galvanized (spray plastic) steel cable trays, stainless steel cable trays, aluminum alloy cable trays, glass steel cable trays, etc. [0004] (1) A3 galvanized (plastic sprayed) steel bridge has the advantages of low cost and simple production process, but at the same time has poor corrosion resistance, easy oxidation and rust, short service life, high th...

Problems solved by technology

[0006] (3) The advantages of aluminum alloy cable trays are beautiful appearance and light weight, but there are also disadvantages such as high cost, low strength, small bearing capacity, easy oxidation of the surface, and high thermal conductivity.

[0007] (4) The advantages of fiberglass cable trays are light weight, corrosion resistance, and long service life, but at the same time, there are disadvantages such as high cost and non-environmental protection.

[0008] The traditional bridge product is a product with low added value. It only needs some simple mechanical processing and surface treatment on the raw material. A considerable part of the cost of the traditional bridge product is the cost of raw materials. The production of cable bridge products consumes a lot of steel , zinc and other natural resources have not created more added value
