Description
Technical field
The present invention relates to a kind of methods for quickly examining antistatic floor paint static electricity resistance.
Background technique
Antistatic floor paint matches curing agent by resin, pigments and fillers, conductive material, diluent and auxiliary agent by a certain percentage
Dual-component coating, have static electricity resistance specific function, be suitable for electronics, communication, computer, precision instrument, powder, You Jirong
Agent, gas, powder magazine etc. all need the terrace and metope finishing system in antistatic place.Antistatic floor paint is generally with epoxy
Resin is carrier, all excellent properties with epoxide terrace paint, can rapid drainage electrostatic charge, antistatic effect is lasting.Mesh
Preceding epoxide terrace paint in the market is based on solvent type and no-solvent type, with increasingly strict, the aqueous epoxy floor of environmental requirement
Paint also increasingly emerges.The other types antistatic floor paint such as polyurethane is more rare.Antistatic floor is divided into finishing coat depending on the application
And priming paint, electrostatic-conductive-type and electrostatic dissipation type are divided into according to static electricity resistance ability again.
The sheet resistance of the painting of electrostatic-conductive-type terrace lacquer painting or coating system in " GB/T 22374-2018 terrace coating material "
It is required to volume resistance: 5 × 104Ω≤resistance value ﹤ 1 × 106Ω；Electrostatic dissipation type terrace lacquer painting applies or the table of coating system
Surface resistance and volume resistance are required to: 1 × 106Ω≤resistance value ﹤ 1 × 109Ω.Making sheet and curing condition are shown in Table A.
The requirement of Table A National Standard Method test plate (panel)
The static electricity resistance numerical requirements and " GB/ of " SJ/T 11294-2003 antistatic floor coatings general specification " to finishing coat
T 22374-2018 terrace coating material " unanimously, the sheet resistance and volume resistance of priming paint require ﹤ 1 × 106Ω。《SJ/T
11294-2003 antistatic floor coatings general specification " test method by GB/T 1410-1989 regulation tested, sample is big
Small is 200mm × 200mm, and sheet resistance test uses insulating substrate, and volume resistance test uses the metal base of well conducting,
Test voltage is by SJ/T 11159-1998 regulation, electrostatic dissipation type l00V voltage, electrostatic-conductive-type 10V voltage.Although not right
Maintenance period is clearly stated, but is typically also maintenance 168h.
" GB/T 22374-2018 terrace coating material " is not exfactory inspection project demand, " SJ/T to static electricity resistance
11294-2003 antistatic floor coatings general specification " it then requires as exfactory inspection item.Execution for antistatic floor paint
