Title: Production of thermoplastic resin composition
Inventor: SUZUKI TAKESHI
IPC: C08L101/00
Filed: 1989-07-10
Abstract: PURPOSE:To obtain a thermoplastic resin composition which does not produce any noxious acidic gas during kneading and is improved in flame retardancy by kneading a thermoplastic resin with thermally expansible graphite of a low acidic impurity content below a specified temperature. CONSTITUTION:Thermally expansible graphite of a pH>=4.5 in a 1wt.% aqueous dispersion thereof is prepared by, for example, a process comprising stirring a graphite powder in a mixture of concentrated sulfuric acid with hydrogen peroxide water, washing the powder well with water, optionally neutralizing it with ammonia water or the like, and drying it. A thermoplastic resin composition is obtained by kneading this graphite with a thermoplastic resin (e.g. polyethylene) with, e.g. a Henschel mixer while keeping the temperature of the melt-mixture at 210 deg.C or below. In this way, the melt-mixture does not reacts acidic, and the flame retardancy of the obtained thermoplastic resin composition can be markedly increased.
