Abstract

The invention provides a sPS (syndiotactic polystyrene) film and a preparation method thereof. The film is prepared from the following raw materials in parts by weight: 100 to 120 parts of modified sPS, 60 to 80 parts of adhesive resin, 10 to 15 parts of Degussa Dyhard 100, 5 to 10 parts of polyether modified polysiloxane, 5 to 10 parts of bis(3,5-tert-butyl-4-hydroxyphenyl) thioether, 1 to 4 parts of decabromodiphenyl ethane, 1 to 3 parts of bis(2,2,6,6-tetramethyl-4-piperidyl)sebacate and 1 to 3 parts of aminopropyltriethoxysilane. The modified syndiotactic polystyrene is added into the film; through the modification by oxidized graphene and aluminium oxide, the prepared modified syndiotactic polystyrene has good mechanical performance and high polarity; the conductivity and the flame-resistant performance are obviously improved; the wide application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of polymer film, in particular to an sPS film. Background technique [0002] FPC is the abbreviation of Flexible Printed Circuit, also known as flexible printed circuit board. It is a printed circuit board made of flexible insulating substrate. It has many advantages that rigid printed circuit boards do not have. Its wiring density is high, Light weight, thin thickness, good bendability. The use of FPC can greatly reduce the volume of electronic products, which is in line with the development direction of electronic products to high density, miniaturization and high reliability. Therefore, FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, smart phones, digital cameras and other fields or products. FPC also has the advantages of good heat dissipation and solderability, easy assembly and low overall cost. With the increase in sales of smart elect...
