Abstract

The invention provides a modified regenerated PVB composite laminated fabric and a preparation method thereof; the fabric comprises a fabric layer and at least one PVB composite layer; a bonding layer is arranged between the fabric layer and the PVB composite layer; the modified regenerated PVB composite laminated fabric is characterized in that the PVB content in the PVB composite layer is at least 40%; the bonding layer is composed of epoxy compounds; and the fabric layer is composed of natural fibers, artificial fibers or a combination of the natural fibers and the artificial fibers; and in addition, additive components such as inorganic filler, a plasticizer, an antioxidant, an anti-ultraviolet agent and a slipping agent can be added into the PVB composite layer of the fabric, so that the performance of the PVB composite layer is improved. When the fabric is prepared, the raw materials of the PVB composite layer are mixed and prepared into a film, and then the PVB film and the fabric layer coated with a binder are bonded and formed under the action of a roller press.

Description

technical field [0001] The invention relates to a composite laminated fabric, in particular to a modified recycled PVB composite laminated fabric and a preparation method thereof. Background technique [0002] Polyvinyl butyral (PVB) laminated glass has been widely used in the field of automotive and architectural safety glass because of its excellent optical properties, aging resistance and safety performance. However, laminated glass is a consumable product, and the annual scrap of automobile windshield and architectural laminated safety glass is huge. Landfilling and incineration of glass are not good ways to dispose of it. How to recycle these discarded laminated glass has become an important research topic in the industrial and environmental protection fields. Glass as an inorganic substance can be crushed and recycled, and then refined into glass or used as a raw material for glass fiber, while the recycling of PVB film has a different direction. [0003] Chinese pa...
