Abstract
The invention relates to a plastic anti-static coating which comprises the following components in parts by mass: 10-50 parts of acrylic resin, 5-20 parts of a nitrocellulose liquid, 10-20 parts of graphite powder, 1-5 parts of carbon black, 5-10 parts of talcum powder, 1-5 parts of tricresyl phosphate, 1-5 parts of dibutyl phthalate and 5-10 parts of a solvent. The coating provided by the invention is coated to a non-metal surface, so that the electrical resistivity in film volume of the coating can be controlled within 10<4>-10<9> ohm, and therefore, generated electrostatic charges can disappear instantly.
Description
Technical field
The invention belongs to paint field, particularly a kind of be applicable to plastics can the coating of anti-electrostatic.
Background technology
Between plastics etc. are nonmetal surface by air-flow and liquid friction or be easy to when clashing into produce and accumulate electrostatic.Accumulation of static electricity acquires a certain degree, will strong-willed static discharge, causes the former device breakdown of various precision instrument, precise electronic and scraps, and even causes the on fire or blast of inflammable and explosive substances, causes huge serious accident.In addition, be accumulated in the electrostatic of surface of plastic products, because dust suction is seriously difficult to elite, thus affect the application of outward appearance in super-clean environment (as Operation theatre, computer room, precision instrument etc.) of goods.
Summary of the invention
The technical problem solved: for the deficiencies in the prior art, the invention provides a kind of plastics Antistatic Paint, solves the non-metal material surfaces such as some plastics and easily produces and accumulate the technical problem of electrostatic.
Technical scheme: for solving the problems of the technologies described above, the invention provides following technical scheme:
A kind of plastics Antistatic Paint, comprises the component of following massfraction: acrylic resin 10 ~ 50 parts, nitrocellulose liquid 5 ~ 20 parts, Graphite Powder 99 10 ~ 20 parts, carbon black 1 ~ 5 part, talcum powder 5 ~ 10 parts, tritolyl phosphate 1 ~ 5 part, dibutyl phthalate 1 ~ 5 part and solvent 5 ~ 10 parts.
Because ABS plastic goods heat-drawn wire is lower, can not adopt baking finish, in air-dried coating, thermoplastic acrylic cold coating is ideal, and component is single, easy construction, moderate.For improving the stream malleability of acrylic coating, solvent is square, heat sensitivity and grinability, can add appropriate nitrocellulose.
Electro-conductive material is important component part, plays conclusive effect to conductivity.Here select wide material sources and the elastic conducting material of reasonable price, wherein Graphite Powder 99 is main conductive material, is aided with carbon black, is used for painted.Being used for of electro-conductive material is most important, directly affects the size of paint film volume specific resistance, and consumption is too little, and volume specific resistance does not reach 10
9below Ω, does not just reach anti-static effect, and Graphite Powder 99 must reach certain consumption, and paint film volume specific resistance just can be made 10
4~ 10
9between Ω, thus play anti-static electrification.
As preferably, in the present invention, described talcous order number is more than 400 orders.Talcum powder is enough fine and smooth, could fully.
As preferably, in the present invention, in described acrylic resin, comprise methacrylic acid or acrylonitrile monemer.Be conducive to the raising of sticking power like this.But such monomer can not use too much, otherwise between molecular resin, force of cohesion strengthens, and causes the viscosity of resin to increase, and obtained paint solid content is low, and paint film fullness ratio is poor.
As preferably, in the present invention, described solvent is one or more in aromatic hydrocarbons, ketone, ester class, alcoholic solvent.
Beneficial effect: the present invention take acrylic resin as main raw material, is aided with electro-conductive material and other additives on this basis, makes paint in nonmetallic surface, and the resistivity that coating can be coated with membrane volume controls 10
4~ 10
9between Ω, the static electric charge produced like this can instantaneously dissolving.
