Embodiment 1

[0016] Put high-density polyethylene, polycarbonate, polyethylene terephthalate, zinc borate, titanium dioxide, silver oxide powder, ammonium polyphosphate, and modified expanded graphite in a reaction kettle at 120°C for 0.1h to prepare film, cooled.

[0017] Among them, high-density polyethylene: 125, polycarbonate: 75, polyethylene terephthalate: 80, zinc borate: 4, titanium dioxide: 8, silver oxide: 5, ammonium polyphosphate: 15, modified expansion Graphite 15.

[0018] Wherein, the modified expanded graphite is prepared by the following process:

[0019] Mix concentrated sulfuric acid, potassium permanganate and graphite by H 2 SO 4 :KMnO 4 : C is 4.3:0.57:1 and treats at room temperature for 60min; dissolves the treated mixture in 0.5% phosphoric acid, adds zinc oxide nanoparticles, mixes uniformly and then dries to obtain modified expanded graphite, wherein the molar ratio of zinc oxide to graphite is 0.17.

Abstract

The invention relates to a composite membrane for a portable electronic product housing and belongs to the field of composite materials. The composite membrane for the portable electronic product housing comprises, by mass, 20-30 parts of polyether-ether-ketone, 50-100 parts of high density polyethylene, 10-20 parts of polyethylene glycol, 1-5 parts of a surfactant, 2-10 parts of a polymerization initiator, 0-5 parts of a pigment, 3-15 parts of composite antibacterial powder, 2-10 parts of expandable graphite and 0-10 parts of alumina powder. The composite membrane has light specific gravity and good antibiosis and flame retardation effects and is especially suitable for a housing material of a tablet personal computer.

Description

technical field [0001] The invention relates to a composite film for a casing of a portable electronic product, belonging to the field of composite materials. Background technique [0002] With the development of science and technology, the miniaturization and portability of electronic products have been realized. The main portable electronic products include tablet computers, mobile phones, living aids, etc., such as tablet computers. Since Apple released the first tablet computer ipad in 2010, Tablet PCs have developed rapidly in recent years. They can browse the Internet, send and receive e-mails, watch e-books, play audio or video, play games and other functions, and are small in size and easy to operate. They are more and more popular with people from all walks of life. The most important feature of the tablet computer is its portability. People can use the tablet computer on any occasion, and only need to store it in the quilt bag, women's handbag, etc. that they carry...
