Embodiment Construction

[0019] The following examples will be more helpful to understand the present invention, but do not limit the content of the present invention.

[0020] In this embodiment, the flame-retardant plastic for communication cables includes the following components by weight percentage:

[0021] Polyvinyl chloride powder: 46.0 parts

[0022] Calcium carbonate: 24.0 parts

[0023] Calcium zinc stabilizer: 2.5 parts

[0024] Antimony trioxide: 2.0 parts

[0025] Polyethylene wax: 0.5 parts

[0026] Diisononyl phthalate: 9.0 parts

[0027] Didecyl phthalate: 15.0 parts

[0028] Soybean Oil: 1.0 parts.

[0029] Among the aforementioned raw materials, the polyvinyl chloride resin is preferably S-65 type resin, so as to obtain better processability, heat resistance, cold resistance, surface and deformability. The calcium carbonate (CaCO3) acts as a filler to reduce the overall cost of the formula. The calcium-zinc stabilizer is preferably 328W type stabilizer, which has better heat...

Abstract

The invention discloses flame-retardant plastics for communication cables and a preparation method thereof. The flame-retardant plastics for communication cables comprises the following components in parts by weight: 46 parts of polyvinyl chloride powder, 24 parts of calcium carbonate, 2.5 parts of calcium-zinc stabilizer, 2.0 parts of antimony trioxide, 0.5 part of polyethylene wax, 9.0 parts of diisononyl phthalate, 15.0 parts of didecyl phthalate and 1 part of soybean oil. The plastics prepared according to the formula of the invention can achieve the combustion level of CMR. Compared with other communication cable formulae, such as CMX and CM / CMG, the invention has the advantages of better flame retardancy, higher environment-friendly performance, higher temperature level and wider application range. Compared with other communication cables made of LSZH and TELFON materials, the invention has the advantages of no need of special processing equipment, simple processing technique and low cost.

Description

technical field [0001] The invention relates to the technology in the field of communication cable insulation materials among industrial polymer materials, in particular to a flame-retardant plastic for communication cables and a preparation method thereof. Background technique [0002] At present, domestic companies that can use PVC to produce ordinary communication cable formulas are more common in companies that pass combustion performance tests such as CMX and CM / CMG levels of combustion performance tests, but if they can pass CMR or even higher levels of combustion such as CMP level but very few. In order to solve this kind of problem that cannot be burned, most CMR and CMP combustion grade wires are made of plastics based on LSZH, TELFON or other materials to produce communication cables, but the corresponding machine equipment costs, manufacturing costs and processing costs will greatly increase; on the other hand, some foreign companies also consider the choice of p...
