Abstract
The antistatic paint is prepared with resin varnish 100(in weight portions, the same below), high structure carbon black 5-40 and preferably 20-25, solvent 15-50, and coupling agent 0.1-0.3. The resin varnish is acrylate, epoxy resin, polyester or polyurethane. The production process includes stoving carbon black at 60-100 deg.c, spraying carbon black with coupling agent, adding carbon blac, resin and solvent successively into container while stirring, and ball milling. The paint of the present invention has the same antistatic effect as antistatic plastic but much less consumption and thus much lower cost, and has no influence on the other performance, such as mechanical performance, of the painted body.
Description
One, technical field: the invention belongs to a kind of speciality coating, especially permanence antistatic coating and preparation method thereof.
Two, background technology:
Prior art, a manufacture method with product (as electronic equipment shell, electronic product packaging vessel etc.) of permanence antistatic performance that obtains as the applicant is to adopt anti-static plastic to carry out injection moulding processing, molded forming.There are a lot of defectives in it; First: anti-static plastic costs an arm and a leg, and is 4-10 times of common plastics, and its moulded product is 3-5 a times of common plastics product; Second: anti-static plastic is because through modification, and descend the to some extent performance (particularly physical strength) of (as shock strength, tensile strength, flowability etc.) its moulded product of the performance of some other aspect is just good not as the common plastics product; The the 3rd:, can not utilize existing mould molding because the material contracts rate of anti-static plastic is different with common material.Need manufacture and design mould in addition, so cost height, cycle are long; The 4th: if the anti-static plastic of static inhibitor (being a kind of tensio-active agent) modification, its antistatic property is unsettled.Change along with the variation of humidity, time.Validity period was from several days to 2 years.
Three, summary of the invention:
The objective of the invention is: overcome above deficiency, a kind of permanence antistatic coating and preparation method thereof is provided, the antistatic property of its coating is stable, and material cost is low, and antistatic property is good, does not destroy product inherent mechanical property and other performance simultaneously.
The object of the present invention is achieved like this: the prescription of permanence antistatic coating:
Form content (g)
Resinous varnish (solid content 30-60%) 100 (admittedly contain thing, according to different coated articles, is selected different product
The resin of planting)
Super-normal structure black 5-40
Solvent or mixed solvent 15-50
Coupling agent 0.1-0.3
The better effects if of super-normal structure black antistatic and over-all properties when 15-25 part more than is a weight ratio.
The preparation method of permanence antistatic coating of the present invention:
(1), carbon black is handled with the coupling agent spray with after the carbon black 60-100 ℃ oven dry;
(2) carbon black, resin, solvent are added in the container in order successively stir, the limit edged stirs into and just mixes thing;
(3) just mix thing and grind, especially poured in the ball grinder ball milling 30-240 minute, leach coating, leave standstill and get product.Ball milling is better at 40-120 minute
The preparation method uses colloidal mill or sand milling to grind not as ball-milling technology.
Constructional method: can spray, can brush.
The prescription of resinous varnish and solvent has multiple choices, and resinous varnish can use esters of acrylic acid, Resins, epoxy, polyester, polyurethane lacquer etc., and solvent is the mixed solvent that matches with it, as pimelinketone, toluene, dimethylbenzene, acetone.The polyurethanes solvent is the mixed solvent that matches with it, as pimelinketone, dimethylbenzene, N-BUTYL ACETATE etc.Coupling agent can be used titanate coupling agent, silane coupling agent etc.Super-normal structure black is different from ordinary carbon black, its secondary structure height, and particle diameter little (several to tens nanometers) is dispersed in and forms three-dimensional network-like structure in the coating, and electric charge can be with three kinds of mechanism conductions by tunnel effect, an extremely emission, conduction.Along with the increase of content of carbon black, the surface resistivity of coating reduces thereupon, and the surface resistivity that can make coating is 10
0Ω/ (OHMSPER SQUARE) is to 10
12Ω/ regulates arbitrarily.
Characteristics of the present invention are: overcome above-mentioned deficiency.The first because coating just carries out application to body surface, consumption seldom, so the cost of material is low, antistatic property is but the same with anti-static plastic; The second, this paint spraying makes object have antistatic property on object, does not destroy simultaneously other performance of object inherent (as mechanical property etc.); The 3rd, this coating can be used for making it have antistatic property on the existing object that does not have an antistatic property.Need not manufacture and design mould, use range is extensive, method is flexible; The 4th, the antistatic property of its coating is permanent stable, and the variation with humidity, time does not change.Super-normal structure black is different from ordinary carbon black, generally is used for reinforcement now, and the present invention uses it for the surface conduction performance that improves polymkeric substance, is much better than carbon black on performance.Especially still has good film-forming properties.
Beneficial effect of the present invention also comprises: simple, the easy construction of compound method of the present invention, application on existing object does not need other molding jig, and cost is reduced greatly.As 18 PCB carriages, as molded and shaped with antistatic plastic, price is 120 yuan/, and physical strength is lower, and uses the common plastics moulding, and price is 23 yuan/, is 33 yuan/after the application, and the physical strength height, and is not easily broken, durable in use.Purposes of the present invention is very extensive, in particular for the surperficial coated of the various plastic containers that use in the electronic industry.
