Abstract
The epoxy resin compound for resisting static electricity contains epoxy resin diluent, dopant, mixed solvent and hardening agent, etc., and possesses the good antistatic property, oil resistance, corrosion resistance, film-forming property, transparency and mechanical property. It is a new-type antistatic material, can be extensively used in various fields of oil field, oil tank, antistatic floor of machine room and antistatic package of electronic products, etc..
Description
This compound belongs to a kind of novel high polymer antistatic material, is applicable to the light anticorrosion and antistatic of petrochemical industries such as oil field, refinery and oil tank, also is applicable to machine room ground, the anti-electrostatic of pit gear and electronic product etc.
Polymkeric substance generally all uses as insulating material in the past, but the resin novel material with conduction or anti-static function that recent two decades is developed begins to show up prominently, and especially compound-type conducting or antistatic macromolecule material develop rapid and obtained widespread use.Resins, epoxy is widely used in coating, flooring material, wall material owing to have good resistance to chemical reagents, cementability etc.But Resins, epoxy has electric insulating quality [volume specific resistance ρ v＞10
14Ohm meter (Ω m)], therefore accumulation static also causes variety of issue thus easily, and for example: accumulation of static electricity can produce electronic product (integrated circuit board, computer component etc.) and destroy; In addition, the fire and the explosion hazard that cause of static sparking also happens occasionally.The statistical information that provides according to China Petroleum Chemicals Corporation: over past ten years, take place in more than 20 the big petrochemical complex electrostatic hazard in enclosing, the fire failure that causes because of oil tank static just has eight.At present, in Resins, epoxy, sneak into conductive metal powder such as bronze in order to prevent accumulation of static electricity from adopting more, silver powder, nickel powder, their good conductivity, and cost an arm and a leg; JP56,159273 and JP64,49360 have reported that with copper powder as conductive filler material, copper powder is cheap, but easily oxidized.In addition, according to document EP 487366A and CN1134968, adopt metal oxide as conductive filler material, because of addition just can reach antistatic effect when big, and the heavy addition amount makes coating produce precipitation and caking, is unfavorable for construction, and price comparison simultaneously is expensive.Carbon is filler such as carbon fiber, carbon black, and acetylene black etc. come into the market as the product that antistatic filler [seeing patent US4035265, CN1133332] makes at present, but still shortcoming such as it is big to exist addition, and poor adhesive force and color are ugly.
In order to address the above problem, Japanese patent laid-open 3-122165 has reported and added the method that basic metal and polyethers polymer obtain stable anti-electrostatic compound in Resins, epoxy.But this method can't form cross-linked network because the polyethers polymer that adds does not react with solidifying agent, so to the original superperformance of Resins, epoxy, as mechanical property infringement is significantly arranged.Purpose of the present invention is exactly in order to overcome not enough shortcoming of the prior art, according to different antistatic mechanism, breaks through traditional method inherent problem, adopts adulterated method to realize anti-static function on the basis that does not reduce the Resins, epoxy performance.Its antistatic mechanism is: under effect of electric field, the ion in the doping agent conducts electricity along with the motion of the segmental in the cross-linked network.And the anlistatig mechanism of traditional method is to come delivered current by a large amount of network paths that electrically conductive particles was formed by connecting.Because the addition of doping agent is few, and is generally colorless substance, makes that so the original performance of Resins, epoxy is remained unchanged, good stability of products can make colourless or light cured article again simultaneously, makes it have more application prospect widely.
The epoxy resin compound of this anti-electrostatic includes Resins, epoxy, thinner, and doping agent, mixed solvent, materials such as solidifying agent, the weight percent of each component consists of:
Resins, epoxy 25～40%
