Description

A kind of hard floor paint possessing antistatic property
Technical field
The invention belongs to coating preparation field, be specifically related to a kind of hard floor paint possessing antistatic property.
Background technology
Electrostatic is a kind of phenomenon of the accumulation due to generations such as contact or frictions, in daily life, because weather, environment, physical influence can produce electrostatic, and the existence of electrostatic can bring harm to metal device, even cause stability to decline and occur the defects such as instrument failure, or there is the serious harms such as burning or blast in metallic oil pipeline etc.
Antistatic coating is the functional coating having conduction and get rid of accumulate static charge ability.Antistatic coating develops with modern science and technology, about has the developing history of over half a century so far.As far back as 1948, the U.S. discloses made the patent of conductive resin by silver and epoxy resin, this be the earliest disclosed in electrically conducting coating.The 1950's, Japan started the Antistatic Paint that production is master with silver system and carbon.The sixties in 20th century American and Britain, Deng state develops antistatic coating in succession.The eighties in 20th century external antistatic technique and electric-heating coatings technology obtain develop rapidly, China also begins one's study in the 1950's and applies antistatic coating.
Antistatic coating is divided into addition type and eigenmode two class, and eigenmode antistatic coating technology is still immature, and therefore a large amount of antistatic coating used is generally addition type coating at present.Addition type antistatic coating is in nonconducting binder resin, add the function that certain conductive filler material realizes static conductive, only has the volume fraction of conductive filler material to reach certain degree and could form conductive network or path, embody the character of conduction.Conventional conductive filler material has: carbonaceous material (carbon black, graphite etc.), metal-powder (silver powder, copper powder, nickel powder etc.), metal oxide semiconductor (stannic oxide, ferric oxide, zinc oxide), conducting nanoparticles and anti-electrostatic auxiliary agent etc.Wherein metal-powder density is large, and forming conductive path needs larger volume fraction, and top layer is oxidizable, can reduce and even lose electroconductibility, and corrosion-resistant, thus affect other performances of coating, therefore metal-powder is subject to a definite limitation as the application of conductive filler material; Static inhibitor temperature tolerance, water tolerance, oil-proofness, erosion resistance, poor durability, antistatic property is unstable; Early stage antistatic coating generally adopts carbonaceous material as conductive filler material, black conductive graphite and carbon black dispersion poor, goods color is black, is not easy to be modulated to other more shallow colors; Along with the development of science and technology, engender the novel conductive fillers such as metal oxide semiconductor and nanometer conductive powder, and applied in antistatic coating, this kind of material color is shallow, is easy to toning, has enriched the colour system of antistatic coating, but addition is large when this kind of material is used alone, dispersion stabilization is poor, can affect coating and and the performance of coating, therefore general and carbonaceous material with the use of.Occurred in recent years using electro-conductive fiber as the antistatic coating of conductive filler material, because electro-conductive fiber diameter is little, length-to-diameter ratio is large, only needs the electro-conductive fiber of seldom amount just can form the network of conduction in the coating, can reduce the impact on other performances of coating.
