| titleOfInvention | Glass fiber ball bundle and preparation method thereof |
| abstract | The invention discloses a glass fiber ball bundle and a preparation method thereof, wherein the glass fiber ball bundle comprises the following components: step 1, crushing and sorting the waste printed circuit board to obtain nonmetal powder; step 2, adding the non-metal powder into inorganic acid, and reacting for 8-40 h at 50-95 ℃; step 3, filtering, and respectively collecting glass fiber powder solid and filtrate; step 4, extracting the filtrate by using an extracting agent to obtain recycled epoxy resin; step 5, mixing the glass fiber powder and the recycled epoxy resin according to the ratio of 100: 0.1-10, adding the mixture into an organic amine solution under stirring, reacting for 0.5-30 h at 40-80 ℃, and filtering to obtain the glass fiber ball bundle. The method of the invention not only avoids the harm of the recycled glass fiber and the glass fiber dust to human bodies in the processes of treatment and recycling, but also can be used as a carrier of catalysts, nano materials and other materials for the recycled glass fiber ball bundles, can be used for directly preparing composite materials, avoids the performance reduction caused by high temperature in the process of extrusion granulation, and has good application prospect. |
