Problems solved by technology

[0015] In the currently disclosed technical solutions, there are many phenomena that take care of one thing and lose another. For example, the flexibility and high and low temperature resistance of TPE are replaced, but the electrical properties are lost; for example, the high and low temperature resistance performance is achieved, but the concept of environmental protection is ignored; Height, but still have to continue to use TPE as the basic raw material, there is no obvious advantage in material cost

Abstract

The invention belongs to the technical field of stabilizing agents, and especially relates to an environmentally friendly stabilizing agent for new energy charging cables. The stabilizing agent at least comprises following components in percentage by weight: 3 to 15% of auxiliary stabilizing agent A, 5 to 15% of main stabilizing agent B, 15 to 25% of main stabilizing agent C, 15 to 62% of hydrotalcite, 2 to 12% of antioxidant D, 1 to 15% of modifier S, and 1 to 8% of surfactant. Compared with the prior art, cables containing the stabilizing agent have an excellent high temperature resistant performance and excellent electro-insulation performance and completely meet the requirements on electro-insulation of new national standards. Moreover, a high temperature resistant polyvinyl chloride material prepared from the stabilizing agent can be used to prepare the insulation layer and sheathing layer of cables; and the prepared cables have the advantages of good wear resistant performance, high flexibility, tear resistant property, good weatherability, low cost, and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of stabilizers, in particular to an environment-friendly stabilizer for new energy charging cables. Background technique [0002] PVC plastic processing is mainly through the modification of the PVC resin base material, supplemented by plasticizers, modifiers, fillers, heat stabilizers and lubricants, etc. The desired product is obtained. Among them, heat stabilizers play a vital role. [0003] There are many types of heat stabilizers for PVC plastics, including heavy metal lead, cadmium, and barium heat stabilizers, calcium / zinc base material composite heat stabilizers (liquid / powder / paste), organotin heat stabilizers and organic-based heat stabilizers. Heat stabilizers, etc. Among them, lead, cadmium, and barium heat stabilizers have been greatly limited in application fields even if they have good performance as the emphasis on environmental protection at home and abroad has increased. Organic heat st...
