Abstract

The invention relates to the technical field of composite material preparation, and discloses a method for preparing a composite material from waste circuit board nonmetal powder. The method comprises the following steps: 1, firstly, disassembling waste computer displays, computer hosts, waste CRTs, televisions, waste refrigerators and other waste articles to obtain circuit boards; 2, carrying out centralized manual cleaning on the obtained waste circuit boards; 3, carrying out centralized crushing on the manually cleaned waste circuit boards to form non-metal powder; 4, carrying out surface modification on the non-metal powder, adding ABS resin and an auxiliary agent, and carrying out high-speed mixing so as to obtain the non-metal composite material; and 5, drying the high-speed mixed non-metal powder. According to the method for preparing the composite material from the waste circuit board nonmetal powder, the composite material is prepared from the waste circuit board nonmetal material and the waste plastic, the traditional mode that the nonmetal material is treated through incineration or landfill is changed, and the problems of resource waste, high treatment cost, environment pollution and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a method for preparing composite material from waste circuit board non-metallic powder. Background technique [0002] At present, the separation and extraction of metal components in the recycling process of waste circuit boards has become a relatively mature industry worldwide. The treatment of non-metal powder remaining after the extraction of metal components is mainly incineration and landfill methods. The processing cost is high, and the pollutants in it may enter the environment through the process of leaching and volatilization, and then be absorbed by the human body, thereby endangering human health and the ecological environment; [0003] Therefore, there is an urgent need in the market for a method for preparing composite materials from non-metallic powders of waste circuit boards to solve the problem that the above-mentioned traditional treatment...
