Abstract

The invention relates to a method for preparing a waste crystal residue / BDADTBHQ type epoxy matrix resin composite material. The method comprises the following steps: drying and pulverizing waste crystal residues, and performing surface treatment with a coupling agent; uniformly mixing waste crystal residue powder with BDADTBHQ type epoxy matrix resin and short fiber so as to obtain a BDADTBHQ type epoxy matrix resin composite material system, filling into a mold, and performing heating pressurization curing molding, thereby obtaining the waste crystal residue / BDADTBHQ type epoxy matrix resin composite material. By adopting the waste crystal residue / BDADTBHQ type epoxy matrix resin composite material prepared with the method has the advantages that the waste crystal residues are efficiently treated, environmental pollution can be eliminated, wastes can be turned into wealth, resource utilization can be achieved, very significant practical meanings can be achieved for comprehensive environment treatment and the like, and good social benefits and economic benefits can be made.

Description

technical field [0001] The invention belongs to the field of high-efficiency treatment of inorganic waste materials and their resource utilization, and particularly relates to a method for preparing a crystal waste residue / BDADTBHQ type epoxy matrix resin composite material. Background technique [0002] my country is one of the first countries to master glass manufacturing technology, and the colored glass products manufactured in the Spring and Autumn and Warring States Periods began to be used for decoration. In the Tang and Song Dynasties, transparent glass bottles and cups were already very delicately made. A large number of imitation gem glass had been exported overseas by the Ming Dynasty. Wu Meicun, a poet at the end of the Ming Dynasty, had a poem praising: "Insert the imperial flower and kiss the phoenix, and Jiangqiang supports the Guanghan ladder." It shows the high level and exquisite technology of glass products in the Ming Dynasty. However, the glass product...
