Problems solved by technology

[0002] With the development of society, the requirements for fire resistance and fracture resistance of cables have also increased accordingly. Some special flexible cables (such as elevator cables, instrument cables, etc.) are also required to have certain flame retardant properties. In the prior art, instrumentation cables The mechanical properties are not good enough, the anti-folding performance is poor, it is easy to age, damage and break during use, and it is not suitable for use in various types of environments

Embodiment 1

[0022] An anti-fracture instrument cable material, the raw materials are as follows in parts by weight: PBT resin: 30 parts, SEBS resin 8 parts, 8 parts trioctyl trimellitate, 7 parts phosphite, γ-glycidyl ether oxygen 4.5 parts of propyltrimethoxysilane, 15 parts of aluminum hydroxide flame retardant, 3 parts of polyethylene wax, 1.2 parts of potassium persulfate, 0.1 part of montmorillonite, 3.5 parts of zinc stearate, 0.15 parts of titanium dioxide;

[0023] The specific manufacturing method of the cable material is:

[0024] (1) Take PBT resin, SEBS resin, trioctyl trimellitate, and γ-glycidoxypropyltrimethoxysilane by weight and mix at high speed for 18 minutes, and then add phosphite, Potassium persulfate, montmorillonite, and titanium dioxide were mixed at high speed for 25 minutes, and finally the remaining raw materials were added. After mixing at high speed for 28 minutes, they were put into a kneader and kneaded at 180°C for 4 minutes, and then taken out to cool;

Abstract

The invention discloses an anti-fracture instrument cable material. The anti-fracture instrument cable material comprises, by weight, 20-40 parts of PBT resin, 5-10 parts of SEBS resin, 5-10 parts of trioctyl trimellitate, 5-10 parts of phosphorous ester, 3.5-5.5 parts of gamma-glycidoxy propyl trimethoxy silane, 10-20 parts of aluminium hydroxide flame retardant, 2-5 parts of polyethylene wax, 0.5-2 parts of potassium persulfate, 0.1-0.2 part of montmorillonite, 2.5-4.5 parts of zinc stearate and 0.1-0.2 part of titanium dioxide. The anti-fracture instrument cable material has more excellent anti-fracture performance, cables can be prevented from being fractured in the using and mounting processes or in various environments, and formula cost control is more reasonable.

Description

Technical field [0001] The invention relates to the field of cable material preparation, in particular to a kind of anti-fracture instrumentation cable material. Background technique [0002] With the development of society, the requirements for the fire resistance and anti-fracture performance of cables are correspondingly improved. Some special flexible cables (such as elevator cables, instrumentation cables, etc.) also require certain flame-retardant properties. In the prior art, instrumentation cables The mechanical properties are not good enough, the folding resistance is poor, and it is easy to age, break and break during use, and is not suitable for use in various types of environments. Summary of the invention [0003] The purpose of the present invention is to provide an anti-fracture instrumentation cable material, which has better anti-fracture performance, so that the cable can avoid the phenomenon of breaking in use, installation or various complex environments, and t...
