A kind of matrix self-loading photocatalytic high-strength high-
toughness polymer and its preparation method, belong to the cross technical field of
solid waste
resource utilization and functional building materials, the
raw material of the
polymer includes the following components by weight parts: base activator 30-50 parts,
silicon-aluminum precursor 100-120 parts, high-activity nanometer
silicon powder recovered from
scrap photovoltaic panel 15-25 parts, surface-modified
glass fiber recovered from
scrap photovoltaic panel 8-12 parts, water 10-20 parts.The present application realizes the full-value consumption of
silicon powder and
glass fiber components in
scrap photovoltaic module by low-temperature
pyrolysis, grading screening and directional modification process, activates the photocatalytic activity of recycled elemental silicon by mechanical chemical means, and assists directional interface modification to strengthen the reinforcing effect of
fiber, so as to realize the deep
coupling of mechanical properties and photocatalytic function in a single
material system.
