Description
Technical field
The present invention relates to a kind of composite materials, it particularly relates to a kind of utilization method of nonmetallic metal powder of scrap circuit boards.
Background technology
There are mainly two types of current old circuit board processing methods, and one is burning disposals, non-in old circuit board
Metal component is burnt up, and recycles metal component, this just causes prodigious pollution to environment；Another processing method is exactly first handle
It is washed after the broken crushing of old circuit board, washes in a pan out metal component and recycle, this has resulted in very serious water pollution,
The non-metal powder separated carries out garbage loading embeading processing, this just wastes valuable land resource, also results in non-metal portion
The waste divided.Therefore, if becoming urgent problem instantly using nonmetallic metal powder of scrap circuit boards to the greatest extent.
Invention content
Mentioned above to solve the problems, such as, the present invention provides a kind of utilization method of nonmetallic metal powder of scrap circuit boards.
A kind of utilization method of nonmetallic metal powder of scrap circuit boards, the preparation method include the following steps：(1) prepare such as
Under each components by weight percent：Supplemented by unsaturated-resin 20-25%, short glass fiber 26-30%, releasing agent and shrinking agent and pigment are referred to as
Material, auxiliary material content are 8%, and pulverized limestone and nonmetallic metal powder of scrap circuit boards are according to 10:1 ratio mixes, and total content is
40%.
(2) unsaturated-resin is added to the container, is stirred；
(3) shrinking agent is added while stirring, adds releasing agent and pigment after stirring evenly, obtains mixture 1；
(4) an alternative container, pulverized limestone and nonmetallic metal powder of scrap circuit boards are uniformly mixed, mixture 2 is obtained；
(5) mixture 2 is added in mixture 1 under stirring, stirring, is eventually adding short glass fiber to get to described
Meet material.
Preferably, the unsaturated-resin is 191 unsaturated-resins and 9800 mold pressing resins, and accounting weight is 20%.
Preferably, the releasing agent is to wind release releasing agent DF-0509.
Preferably, the shrinking agent includes polystyrene.
The beneficial effects of the present invention are the entirety of pulverized limestone and nonmetallic metal powder of scrap circuit boards mixing as a reaction
The making of composite plate is participated in, instead of pulverized limestone in the prior art, nonmetallic metal powder of scrap circuit boards has obtained efficient utilization.This
Invention provides the utilization method of nonmetallic metal powder of scrap circuit boards, by the way that nonmetallic metal powder of scrap circuit boards is added in composite material,
The dosage of composite material is saved, production cost can not only be saved, and do not change the performance and quality of composite products, most
Big benefit with the Non-metallic components that make full use of old circuit board, provide a very large space to improve environment, obtain
Obtain larger economic benefit and environmental benefit.
