[0002] With the rapid development of the world economy, the power consumption is also increasing rapidly, the construction of power grids and power facilities is accelerating, and the amount of insulators is increasing. However, the traditional porcelain insulators have the following shortcomings: production needs to mine a large amount of clay, serious Destroying the ecological environment; traditional kiln sintering in the production process consumes a lot of energy and emits a lot of smoke and dust pollution; traditional porcelain insulator products are heavy, especially difficult to install and construct at high altitudes, and labor-intensive; easily polluted by pollution, requiring Spend a lot of manpower to remove the pollution on the insulators of overhead lines, otherwise it will affect the safe operation of the lines
[0003] Due to the above deficiencies, foreign countries are focusing on the research and development of polymer insulators, and my country is also carrying out the research and development of polymer silicone rubber insulation, but due to its high price, performance can not fully meet the demand, and its application is limited

Abstract
The invention relates to a preparation method of a modified polymer insulator material. The preparation method of the modified polymer insulator material comprises the following steps of: pre-heating an internal mixer to 150 DEG C to 160 DEG C; dropping an upper top bolt after adding polypropylene, banburying for 115 seconds to 125 seconds under the pressure of 0.5MPa-0.6MPa and temperature of 150 DEG C to 170 DEG C; then adding polythene and banburying for 115 seconds to 125 seconds under the pressure of 0.5MPa-0.6MPa and temperature of 150 DEG C to 170 DEG C; raising the upper top bolt, banburying for 115 seconds to 125 seconds under the temperature of 150 DEG C to 170 DEG C; and finally discharging, cooling and pelletizing, wherein the molecular weight of each of polypropylene and polyethylene is 10 thousand to 20 thousand. The modified polymer insulator material prepared by the preparation method not only can satisfy the electrical characteristics and mechanical performance requirements of the insulator, but also can satisfy the service life requirement. Besides, the preparation method has an antifouling self-cleaning function and has the advantages of high cost performance, energy conservation and environment protection and no pollution, so that the product can be recycled after reaching the service life.
