Method for producing a composite organic-ceramic film with piezoelectric properties and a composite of piezoelectric properties

摘要

the subject of the invention is a manufacture of composite organo ceramic composite and piezoelectric properties of piezoelectric properties. way is first to warp granules, polypropylene (pp) is added in the known way (pudrowanie) modifier.then ujednorodnia all composition to form regranulatu, processed to form a film, which orientate and subjected to polarization. in the way that warp and is granular polypropylene (pp) with a regular (syndiotaktyczny or izotaktyczny) degree wykrystalizowania? 60%.such granules are added in powder form an compound kaolinite and silica, in quantities of 1 to 20 mass%. from the homogenised composition shall be moulded plastic with a thickness of 100 mm and realises her one - or biaxially in the range from 2: 1 to 5: 1, at a temperature of 80 to 100u00b0c. oriented film gone bipolar in electric fields at 50 to 150 v / mm at a temperature of 60 to 100u00b0c.composite contains 80 to 95%. polypropylene (pp) to build the regular and degree wykrystalizowania? 60% and 5 - 20%. an. modyfikatorem mixture is submikrokrystalicznej silica and kaolinite platelet with a particle size of - 1.5 u00f7 6,0 mm, in which the content of kaolinite is 35% mas., crystalline silica sio2 content is 55%.and the content of amorphous silica sio2 - 10%.
