Abstract

The invention discloses an antistatic anti-yellowing PP / POE plastic for automotive interior parts and a preparation method thereof. The antistatic anti-yellowing PP / POE plastic for automotive interior parts comprises the following components in parts by weight: 100 parts of PP resin, 15-30 parts of POE plastic, 2-15 parts of antistatic agent and 0.5-2 parts of anti-yellowing agent. Preferably, the antistatic agent is one or a mixture of more of glyceryl monopalmitate, N-oleoyl-N',N'-diethyl ethylenediamine-hydrochloride, 3-sulfopropyl dodecyl dimethyl betaine and carbon black; and the anti-yellowing agent is one or a mixture of more of dibutyl hydroxy toluene, tri(2,4-di-tert-Butylphenyl)phosphite, 4,4'-di(phenylisopropyl)diphenylamine and pentaerythritol tetra[beta-(3,5-di-tert-Butyl-4-hydroxyphenyl)propionate]. According to the invention, the antistatic anti-yellowing PP / POE plastic has low production cost, good processability, favorable antistatic property and anti-yellowing property and environment friendliness. The antistatic anti-yellowing PP / POE plastic for automotive interior parts is especially suitable for injection molding of various automotive interior parts.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a modified PP / POE plastic and a preparation method thereof, in particular to an antistatic and anti-yellowing PP / POE plastic for automotive interior parts and a preparation method thereof. Background technique [0002] Polypropylene, abbreviated as PP, was first put into industrial production in Italy in 1957 and is another important plastic species after polyethylene (PE). It has good heat resistance, and it will not be destroyed when it is cooked at 135°C for 1000 hours. The specific heat capacity and thermal conductivity of PP are smaller than that of PE, but its thermal insulation is better than that of PE. PP is a non-polar polymer with excellent dielectric and electrical insulation properties. The electrical properties are basically not affected by ambient humidity and electric field frequency. Within the allowable operating range, the increase in tem...
