Abstract

The invention belongs to the technical field of waste recycling, and particularly discloses a filling material formed by recycling non-metal powder of waste circuit boards and a preparation method of the filling material. The filling material is composed of, by weight, 25%-65% of solid plastic, 25%-65% of waste circuit board non-metal powder and 8%-12% of processing aid. The preparation method comprises the following steps: preparing materials, conducting mixing, feeding and granulating, and conducting shearing and plasticizing by using a parallel twin-screw granulator, thereby obtaining the filling material, wherein the preheating temperature is set to be 120-250 DEG C, and the granulating temperature is set to be 130-300 DEG C. According to the technical scheme, harmless recycling of the non-metal powder of the waste circuit boards is achieved, waste plastic can also be utilized at the same time, the formed filling material is wide in application and large in filling amount during use, and the preparation process is simple, convenient to operate, low in cost and good in environmental protection performance.

Description

technical field [0001] The invention belongs to the technical field of waste recycling, and in particular relates to a filler formed by recycling waste circuit board non-metallic powder and a preparation method thereof. Background technique [0002] Environmental pollution refers to natural or man-made destruction, the act of adding certain substances to the environment and exceeding the self-purification ability of the environment to cause harm, thus having a harmful impact on the growth and reproduction of organisms and the normal life of human beings, and destroying the ecological system and human beings. Normal production and living conditions. [0003] There are 6 to 8 million tons of waste circuit boards produced in my country every year. Waste electronic circuit boards are a mixture of glass fiber reinforced resin and various metals. The most typical electronic waste belongs to the category of hazardous waste. It will cause a large loss of useful resources and cause s...
