Abstract
The colorful permanent antistatic coating is that the ratio by weight of filling a prescription is: Resin varnish 100, it is the white powder 40 not conductive, pigment not colored or 40 dyestuffs, solvent or mix 50 solvent, unite 0.3 pharmaceutical occasionally. White the conductive powder of color characters and voers the sulphuric acid barium for the metal membrane, glimmer powder, two Oxidize titanium or P-S-T half conductive powder, resin varnish the propylene Acid ester, polyester or polyurethane. This invention has overcome the existing skill The skill is insufficient, there is little coating consumption, so the material is with low costs, But and skill is insufficient, there is little coating consumption, so the material is with low costs, But andantistatic plastics and black are resisted for ever for antistatic performance. The static coating is the same; This coating can be used in existingly not to have On the object of antistatic performance, make it have antistatic performance. Does not need to design and make membrane and have, suitable and in extensive range, the method Flexible; This invention compound method is easy, construction is convenient, it is put to paint at existing object, forbid separately making the mould, make the cost is reduced greatly.
Description
One, technical field: the invention belongs to a kind of speciality coating, especially colorful permanence antistatic coating and preparation method.
Two, background technology:
Prior art, two manufacture method one with product (as electronic equipment shell, electronic product packaging vessel etc.) of permanence antistatic performance as the applicant's application are to adopt anti-static plastic to carry out injection moulding processing, molded forming, the 2nd, adopt the black permanence antistatic coating that adds high structure carbon black to carry out the surface spraying and form, see Chinese patent application 03113067.There are some 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.Therefore the 4th: behind the black permanence antistatic paint spay-coating, the product surface color and luster is single, and application in some aspects is restricted, as wallcovering, floor coating etc.; The the 5th:, obscure easily because solid colour can't be distinguished on directly perceived; The 6th: black permanence antistatic coating needs ball milling in layoutprocedure, production efficiency is not high.
The method for making of adularescent conducting powder occurs, and is ZnOws of surface clad layer as 99117402 methods, and its surface is coated with a kind of pure metal or alloy layer at least.The thickness of pure metal or alloy layer determines as required, is generally 10 nanometers～10 micron.
Three, summary of the invention:
The objective of the invention is: overcome above deficiency, a kind of permanence antistatic coating and preparation method with multicolour is provided, the antistatic property of its coating is stable, can be modulated into multicolour, from the effect of playing sign directly perceived, and attractive in appearance, and process for preparation is simpler.
The object of the present invention is achieved like this: the prescription of colorful permanence antistatic coating:
Form content (g)
Resinous varnish 100 (,, selecting the resin of different varieties) according to different coated articles admittedly contain thing
White conductive powder 10-40
Coloured pigment or dyestuff 5-40
Coupling agent 0.1-0.3
Solvent or mixed solvent 10-50
The better effects if of white conductive powder antistatic and over-all properties when 15-35 part.
The preparation method of colorful permanence antistatic coating of the present invention:
1. with 60-100 ℃ of oven dry of white conductive powder;
2. white conductive powder, coloured pigment, coupling agent, solvent or mixed solvent are added the container high speed and stir, be uniformly dispersed;
3. resinous varnish is added the said components high speed and stir, be uniformly dispersed.
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, and solvent is the mixed solvent that matches with it, as pimelinketone, dimethylbenzene.Also can use polyester, polyurethanes, solvent is the mixed solvent that matches with it, as pimelinketone, dimethylbenzene, N-BUTYL ACETATE.Coupling agent can be used titanate coupling agent, silane coupling agent etc.The white conductive powder can be metallic membrane coated insulation material powder granule such as titanium dioxide, mica, barium sulfate etc., also can be conduction and semiconductive material powder granule such as conductive zinc oxide whisker, P-S-T body conducting powder etc.
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 and black permanence antistatic coating; 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.
The beneficial effect of the 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 38 yuan/after the application, and the physical strength height, and is not easily broken, durable in use.
