The invention belongs to the technical field of composite materials, and particularly relates to a modified resin
powder filling master batch and a preparation method and application thereof.The filling master batch takes recycled waste circuit board
epoxy resin as a matrix, modified resin
powder is obtained after
coupling agent modification treatment, and efficient recycling of waste resources is achieved. Through synergistic
toughening modification of linear low-density
polyethylene and
maleic anhydride grafted
polyethylene, the mechanical properties of the material are significantly improved. Meanwhile,
activated aluminum oxide and
nano silicon dioxide are adopted, so that the
heat resistance and the size stability of the material are improved. In addition, by optimizing the anti-aging agent and the
lubricant, the processability and durability of the material are further improved. The filling master batch has the excellent characteristics of light
specific gravity, high strength, good
heat resistance, strong
corrosion resistance and the like, has the advantages of
environmental protection and cost, not only solves the problem of
recovery of waste resin, but also remarkably reduces the production cost, conforms to the development concept of
green manufacturing, and can be widely applied to the fields of
electronic packaging, automobile parts and the like.
