Abstract

The invention is applied to the technical field of materials, and provides a data cable housing and a preparation method thereof and a data cable. The data cable housing is prepared from, by weight, 80-100 parts of a modified ethylene propylene diene monomer, 15-20 parts of microencapsulated red phosphorus, 3-7 parts of benzalkonium chloride, 13-18 parts of polyester adhesive powder and 4-6 partsof an assistant; the modified ethylene propylene diene monomer is prepared through the following steps that 35-40 parts of an ethylene propylene diene monomer, 10-25 parts of methylbenzene, 3.5-4.2 parts of an initiator, 17.5-20 parts of acrylonitrile, 5-9 parts of kaolin and 0.8-1.2 parts of a cross-linking agent by weight are weighed according to the formula; the ethylene propylene diene monomerand the methylbenzene are put in a reaction vessel, stirring and mixing are carried out for 5-15 hours, and a first mixture is obtained; after heating is carried out to 75-85 DEG C, the initiator andthe acrylonitrile are added, a stirring reaction is carried out for 2.5-4 hours, and a second mixture is obtained; heating is carried out to 140-155 DEG C, the kaolin and the cross-linking agent areadded, a stirring reaction is carried out for 1-2 hours, and the modified ethylene propylene diene monomer is obtained. The data cable housing has good insulativity, elasticity, toughness, ageing resistance and yellowing resistance and high safety.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a data line casing, a preparation method thereof, and a data line. Background technique [0002] With the continuous development of the electronics industry, as a connection medium between electronic devices and electronic devices or power sources - data lines have become an indispensable part of our lives. The data line is roughly divided into two parts, one is the shell, and the other is the internal circuit wrapped in the shell. The material of the shell is closely related to the performance of the data line, such as physical security. The high-quality data cable casing can protect the internal circuit covered by it and avoid the influence of the external harsh environment during use, resulting in leakage, breakage and other failures, thereby ensuring the stability and safety of data transmission and improving the use of data cables. life. [0003] Since PVC (...
