Abstract: Fluorocarbon tank than the traditional static conductive coating Epoxy resin Static conductive coating film with superior performance, use of fluorocarbon resin as the membrane material, metal oxide coated with light-colored Mica Powder as conductive filler, were used to add type antistatic anticorrosive paint, through research and testing, the proposed product antistatic coating for the coating resistivity control in 106 ~ 107 /cm2 is appropriate, the use of control 105 ~ 109 /cm2. The performance test standard, to meet market and customer needs. Key words: PVDF antistatic coating; fluorocarbon resin; mica; resistivity 0 Introduction Static conductive coating is a certain conduction current (Ps5.0 × 104 ~ 1.0 × 106 /cm2) and the dissipation of electrostatic charge (Ps1.0 × 106 ~ 1.0 × 109 /cm2) the functional capacity of coatings, intrinsic type and added into two major categories of type [1]. Intrinsic type has a conductivity stability, durability and good, but expensive, at present mainly used in telecommunications, and military fields. Add a type because of its easy production, easy construction, low prices are widely used in petroleum Chemical industry , Transportation, aerospace, building materials and other fields, especially in the oil during storage and transportation of finished products, to ensure the safety tank to ensure fuel quality, the State Technology Supervision Bureau have issued GB13348-92 "liquid petroleum products static safety order ", GB6950-2001" static conductivity light oil security "and other mandatory standards and technical specifications related to the resistivity (Ps) index of 105 ~ 109 /cm2, to ensure that the tank wall paint with the full ability to dissipate static charge . 2005 China Feed Industry Association and the "oil tank is static coating testing standards" for the management team developed and launched jointly organized CNCIA-HG/T0001-2006 "Petroleum Tank anticorrosion coating Painting And acceptance of "static conductive coating for the tank construction quality. Currently applied antistatic anticorrosive paint, with epoxy resin as the membrane material, the carbon system Powder Add black as conductive filler conductive coating, due to pollution of oil, oily poor permeability, color dark, inconvenient inspection, maintenance and other reasons, "the oil tank is static coating testing standards" for the management group in August 2006 on-site inspection report has been proposed is not suitable for light oil, aviation oil in the tank can not be used for wall, requires a light color antistatic coating. At the same time as the tank large scale (> 100,000 m3), long lifetime (> 20a) [2] and Import High sulfur content crude oil, acid value large, high content of heavy metals of lead, corrosion and parts of the steam heating oil needs ( 80 ) the use of antistatic coatings made new demands. View of the fluorocarbon resin has the general Synthetic resin Difficult to match the outstanding performance, this paper fluorocarbon resin as the membrane material, metal oxide coated with light-colored mica as filler, were used to add anti-corrosion coating type antistatic to meet market and customer needs. 1 Test section 1.1 technical requirements of raw materials and raw materials Raw materials are fluorocarbon resin, isocyanate Curing agent , Epoxy, light-colored conductive fillers, pigments and fillers, additives, solvents, including curing agents, additives for the import, the rest domestic. The technical requirements of the main raw material in Table 1 to Table 3.
