Document Type and Number:
WIPO Patent Application WO/2019/233017
Kind Code:
A1
Abstract:
Disclosed is a formula of a modified polyphenylene ether foam bead, and a preparation method and an application thererof. The formula comprises the following components, in parts by weight: 30-90 parts of polyphenylene ether, 30-90 parts of modified polymer, 5-30 parts of a compatibilizer, 5-30 parts of a toughening agent, 5-20 parts of a flame retardant, 1-5 parts of an antioxidant, 1-5 parts of a secondary antioxidant, 1-3 parts of a lubricant, 1-3 parts of a coupling agent, 1-10 parts of a dispersant, and 2-6 parts of an inorganic nano-nucleating agent material. The invention can be used to produce a foam bead that is uniformly foamed, having large magnification, a high closed-cell ratio, uniform and fine cells, and that is not easy to shrink and collapse. The production of the modified polyphenylene ether foam bead is completed using fast, safe, energy-efficient pre-foaming equipment and processing.
