A composition and manufacturing method of flame retarding rubber/plastics foams with low toxic gas liberation and low smoke density under fire atmosphere

摘要

The invention toxic gases and smoke relates to a a flame-retardant rubber / plastic foam composition and a method for manufacturing minimal density, more specifically, according to the rubber-based resin, polyolefin-based resin and when the resin is a (closed) tire rubber powder ( using GTR), blend the cumarone resin and the inorganic metal hydroxide as a flame retardant herein, organophosphorus compounds, zinc-borate, yellow earth, charcoal, etc., and other additives (a composition prepared by mixing a foaming agent, a crosslinking agent, and the preparation and the like), in particular If you are using a wide range of applications such as environmental friendliness and reliability are excellent and excellent flame retardancy and mechanical properties, extrusion, compression or injection various building materials and auto parts by molding, railroad parts, sporting goods, and other industrial products environmentally friendly and stability, flame resistance, etc. are obtained with minimal toxic gases and smoke density of a new composition that can be used very useful flame retardant Rubber / plastic foam relates to a composition and a method of manufacturing the same. Thus the present invention has been fully excluded halides for discharging harmful gases in case of fire is designed so that a relatively higher cha (char) is formed.
