Title:
耐熱性に優れた超軽量の難燃性断熱材組成物とその製造装置およびこれを用いた製造方法
Document Type and Number:
Japanese Patent JP4229267
Kind Code:
B2
Abstract:
Disclosed are an ultra-light insulation material composition with superior flame-retardant and thermal resistance characteristic, an apparatus for manufacturing the composition, and a method for manufacturing the composition by using the apparatus. A flame-retardant layer including inorganic nonflammable material is formed on a surface of a chip, which is obtained by pulverizing expended polystyrene resin in a size below 3 mm. Through compress-kneading and pressing works with adding thickener, flame-retardant, curing control agent, auxiliary adhesive, dyes/pigments, and waterproofing stuff. The insulation material composition is subject to a pressing work including a vibration pressing work, a press pressing work, and an extrusion pressing work, so that the ultra-light composition can be rapidly obtained. Waste resource is reused and a tire and poisonous gas caused by the insulation material can be prevented. The composition makes a great contribution for solving a pollution problem and disposable polystyrene can be reused.
