AI Technical Summary

Technical Problem

Acrylic light-transmitting panels used in sound insulation walls on highways face issues with deterioration over time, necessitating replacement and traditional recycling methods do not fully leverage chemical recycling potential for resource efficiency and environmental impact reduction.

Method used

Manufacture roadside acrylic translucent panels with multiple layers, including at least one layer made from recycled materials, with a soft acrylic layer sandwiched between two acrylic cast plates, and optimize the recycled material usage rate between 16% and 80% by weight.

Benefits of technology

Facilitates effective recycling and reduces CO2 emissions by up to 60% compared to virgin material usage, while minimizing transportation and management costs through localized manufacturing of layers.

Abstract

We provide acrylic translucent panels for roadside installation that use recycled materials obtained through chemical recycling. [Solution] In a roadside acrylic translucent panel made of multiple layers of laminated acrylic material, at least one layer of acrylic material in each layer is made using recycled material. Specifically, the laminated acrylic material consists of a multi-layered acrylic cast plate 11 and a soft acrylic layer 12 sandwiched between them. The recycled material usage rate is set to be 16% by weight or more and 80% by weight or less of the total weight of the multiple layers of laminated acrylic material. The layers of acrylic material containing recycled material and the layers of acrylic material consisting only of virgin material are molded separately, and then these layers of acrylic material are laminated and fixed together.
