Method of producing an acrylic material

摘要

A method of producing an acrylic polymer sheet material comprising the steps of: mixing a composition of material comprising 0.5-2% by weight of metallic flakes having a maximum dimension in a range from 20-300µm and dispersed in a plasticiser, a radical initiator, with the balance being an acrylic prepolymer for the production of a transparent polymer in a vessel; introducing the viscous material into a mould; permitting the composition to polymerise under controlled conditions so the concentration of the flakes increases through the thickness of the sheet; and removing the polymerised material from the mould.
