摘要：
Algae-resistant roofing shingles are formed by extruding a mixture of mineral particles and a binder to form porous granule bodies, and algaecide is distributed in the pores to provide alqae-resistant granules, which are subsequently applied to roofing shingles. Release of the algaecide is controlled by the structure of the granules.
