Embodiment Construction

[0031] The aramid paper-PPS laminate of the invention of the present application is obtained by laminating the aramid paper and the PPS film after performing plasma surface treatment, and laminating these components at a temperature of 30°C to 50°C by a pair of pressure rollers. Manufactured by pressing a pressure of 500kgf / cm or more or at a temperature of 50°C to 100°C and a linear pressure of 200kgf / cm or more by a pair of pressure rollers.

[0032] Aramid paper, specifically the m-aramid paper known under the registered trademark of DuPont's ノ-メツクス, is made of aramid fiber and aramid pulp made of polyisophthalamide-containing It is composed of m-phenylenediamide (meta-aramid fiber) or its main component copolymer or mixed copolymer. There are no particular limitations on the component or the amount of the component to be copolymerized or mixed with the meta-aramid as long as the properties of the meta-aramid are not lost. For example, the components thereof include tereph...

Abstract

Disclosed is a method for manufacturing an adhesive-free laminate of an aramid paper and a PPS sulfide film, the method comprising steps of: providing the aramid paper made from aramid fibers and aramid pulp and subjected to a plasma surface treatment; providing the PPS film subjected to a plasma surface treatment; and laminating and bonding the plasma surface treated aramid paper and the plasma surface treated PPS film at a roll temperature of 30 DEG C or higher but lower than 50 DEG C under a linear load of 500 kgf / cm or higher with a pair of press rolls, or at a roll temperature of 50 DEG C or higher but lower than 100 DEG C under a linear load of 200 kgf / cm or higher with a pair of press rolls.

Description

technical field [0001] The present invention relates to a method for producing an adhesive-free aramid-polyphenylene sulfide laminate in the form of a sheet, a lath, or a tape, which can be used as an insulating material, etc., an insulating member and an insulating structure of a rotating electric machine. Background technique [0002] Aramid fibers are aromatic polyamides known as No-Mex (registered trademark of du Pont), and are used in many fields especially as electrical insulating materials because they are excellent in electrical insulation, heat resistance, and chemical resistance. [0003] Conventionally, there are known aramid-polyester laminates in which aramid paper produced by mixing aramid fiber and aramid pulp, polyester film or sheet is laminated and bonded by an adhesive (refer to Patent Documents 1 to 5). ). [0004] Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2003-246018) discloses a plasma-treated aramid film and a prepreg s...
