Description
Technical field
The present invention relates to anti-static coating liquid, more particularly to the anti-static coating liquid being applied in RC printing paper.
Background technique
The substrate that photosensitive material uses is due to extreme hydrophobicity, so easily adsorption electrostatic lotus, therefore coating,
Dry, cut, transporting and later period use process in, often generate high-pressure electrostatic because of friction, form electrostatic spot.Usual positive charge
Electrostatic spot is shown as, negative electrical charge shows as dendroid.With the raising of photographic emulsion sensitivity, the raising of Coating Speed, ring
The reduction of border humidity, the probability that electrostatic spot generates increase, cause the large quantities of products to scrap when serious, cause greatly to lose.RC high
Light printing paper be with printing paper of the double plastic-coated lamination printing paper base stock after multi-layer coated, RC bloom printing paper since equipment investment is larger,
Application frequency is more, and technique is more complex, and yield rate is lower, thus avoid the loss for leading to finished product because of electrostatic interaction be at present urgently
It solves the problems, such as.
Currently used antistatic technology is that usually a small amount of antistatic agent is added in plastics using antistatic agent
Portion is coated directly onto plastic product surface, and electrostatic generation can be effectively suppressed.Antistatic agent can be divided into surface by molecular structure and live
Property agent class antistatic agent and Polymer Antistatic Agent two major classes.Currently used antistatic agent mainly has cationic antistatic
Agent, anionic antistatic agent, non-ionic antistatic agent, both sexes antistatic agent, Polymer Antistatic Agent.And the table of product
Surface resistivity is 106-1012The antistatic effect of ohm/sq is maximum, and how to reduce surface resistivity as far as possible in the range is
A problem of industry at present.
Disclosed in patent CN104194046B a kind of mesoporous nano material/compound anti-static agent of surfactant type and its
Preparation method and application.The invention is to use mesoporous nano material for carrier, and traditional surfactant electrostatic agent molecule is sealed
Loaded on a kind of New-type long-acting composite antistatic agent in mesoporous nano material, is prepared into, which not only has conventional surface living
Property type antistatic agent excellent antistatic capability, while also have stronger slow releasing function, antistatic work can be effectively improved
Timeliness, persistence, the surface resistivity using the product of anti-static agent coating are 109-1010ohm/sq。
A kind of preparation method of antistatic agent, including Gemini surface-active are disclosed in patent CN103741465B
Agent, high molecular weight chains alkylol phosphate, polyester are prepared, and the good water solubility of the antistatic agent, bubble are small, have good
Heat resistance and resistance to acid and alkali, antistatic effect, the surface resistivity of product can be 108-1010Ω/m。
However antistatic agent also largely effects on its antistatic effect in the adhesion property of product surface, while influence its resist it is quiet
The stability of electric energy power, therefore the antistatic property of product how is improved, while keeping stable antistatic effect is a skill
Art problem.
