Problems solved by technology

However, it is found in production that when such additives are directly added to the resin for use, its extremely low dosage is difficult to disperse evenly, especially when it is blended with pellets, this problem is particularly prominent, and there are still problems in production dust pollution problem

Embodiment 3

[0026] Example 3 Graphite was weighed into a plastic cup followed by the addition of solvated resole. The graphite and the solvated resole were premixed for 1 minute prior to the addition of the acid. After adding the acid, the pasty mixture was mixed for 30 seconds, then transferred to a 2 cm x 2 cm x 1 cm plastic mold and pressed manually. After 24 hours, the resistivity of the cured molded sample polymer was measured with the multimeter used in Example 1. The results obtained are shown in Table 1.

Abstract

The invention relates to a highly-conductive and high temperature resistant polymer. The polymer is characterized by being composed of the following components in parts by weight: 15 to 25 parts of polyamide resin, 10 to 15 parts of resole phenol-formaldehyde resin EPR, 20 to 30 parts of p-toluenesulfonic acid, 25 to 30 parts of fluorine-containing polymer, 10 to 15 parts of active polyol stearate, and 5 to 10 parts of a thermal stabilizer with a CuI / KI ratio of 1:8. The resole phenol-formaldehyde resin EPR is added, and thus the polymer can be used as an electrode or an electrode shielding material. The polymer can inhibit electromagnetic interference and prevent electrostatic discharge in a position, and is a carrier-free polymer with advantages of wide universality, good heatproof performance, and excellent conductive property.

Description

technical field [0001] The invention relates to a polymer and a preparation method thereof, in particular to a high-conductivity high-temperature-resistant polymer. Background technique [0002] The sources of polymers are divided into natural polymers (such as cellulose, starch, etc.), synthetic polymers (such as chlorinated phosphazene rubber, various vinyl polymers, etc.) and semi-synthetic polymers (such as cellulose acetate, etc.). According to the name of the synthesis reaction, it is divided into addition polymer (ie, addition polymer), condensation polymer (ie, condensation polymer) and ring-opening polymer. According to the application function of the polymer, it is divided into general polymer, special polymer, functional polymer, bionic polymer and medical polymer. [0003] In order to obtain low production costs, it is desirable to extrude polymers at high rates. Higher extrusion rates can easily be obtained by increasing the extruder screw speed. However, thi...
