Zusammenfassung: | PURPOSE:To obtain super advantages such as mechanical strength, buckling strength, bend resistance, appearance, impact resistance, secondary processing, surface electroconductivity, heat resistance and solvent resistance as well as a long lasting stable surface specific resistance value by providing an electroconductive paint layer with a surface specific resistance value which is lower than a specific value on one surface of a base sheet of styrene resin composition having an excellent solvent resistance. CONSTITUTION:A plastic sheet with an electroconductive surface consists of an electroconductive paint layer with a surface specific resistance value of 10 OMEGA or less, provided, at least, on one surface of a base sheet of highly solvent- resistant styrene resin composition. The highly solvent-resistant styrene resin composition is a polymer alloy consisting of 1 to 50 pts.wt. of compatibilizer added to 100 pts.wt. of the resin composition comprising 90 to 50wt.% of styrene resin B and 10 to 50wt.% of polyolefin C. The compatibilizer to be used is one having 1 or less of the melt viscosity ratio C/B of the polyolefin C to styrene resin B at 160 to 250 deg.C of kneading and molding temperature and easily forming a skin layer of polyolefin C on the surface. |
