摘要
Provided is a method of producing poly(vinyl butyral) laminate from discarded laminated glass. By means of breaking the discarded laminated glass, water-washing and grinding the reduced glass fragments, a reusable poly(vinyl butyral) material substantially free of glass pieces is obtained by physical treatment without using any organic solvent. After drying, granulation and formation steps, a poly(vinyl butyral) laminate is further obtained from the poly(vinyl butyral) material. Accordingly, the method not only reduces resource waste but also produces a water-proof poly(vinyl butyral) laminate, and is more environmentally friendly and more applicable to industry.
