Description
Technical field
The invention reside in manufacture method and structure thereof that a kind of rubber is provided, espespecially a kind of manufacture method of antistatic rubber and structure thereof.
Background technology
Along with the prosperity of information, electronics and semiconductor industry, the electronic product of the industry manufacturing of these pipoint techniques is all quite responsive for static, need to avoid the interference of static when therefore making electronic product, in order to avoid have influence on the function of electronic product.Common static discharge is to cause most electronic package or electronic system to be subject to the excessively electrically principal element of stress rupture, and this destruction can cause electronic package or electronic system to form a kind of permanent breaking-up, and so that electronic product is undesired.And the generation that static discharge destroys, mostly be because human factor causes, because electronic product manufacturing processed, test or transport the way in, static can be accumulated in human body, instrument or the storage facilities, even also can accumulate static at electronic product itself, and people are in contact with one another these objects in unwitting situation, thereby the formation discharge path, so that electronic product suffers the destruction of static discharge.
The production process of static is when two Nonconductor surfaces rub mutually rear separating, and has the electric charge that some excessive dissipations are not fallen on the surface, after charge accumulation arrives to a certain degree, electrostatic interaction will occur.And industrial static can prevent by adding carbon black or static inhibitor, but use carbon black that many shortcomings are but arranged, as be subject to rub and have the phenomenon that comes off can polluted product, and usually be not suitable under the environment of drying, using, so just must control pass through baking oven speed and temperature in the paperhanging work section, cross light engineering section cooling wheel temperature etc., pollute the problem of glue face to avoid carbon black.Static inhibitor has following problem values must go to inquire on using in addition:
(1) weather resistance: plastic warp rubs repeatedly, and most of static inhibitor is stripped from easily, and character can consume gradually.
(2) surface property: rate of migration and the control of migration amount are difficult for, the migration amount reaches rate of migration less, and then poor effect and prompt effect are poor when slow, but the problem that the migration amount is too many or rate of migration can cause again grumeleuse and stick together when too fast, coating, the heat seal point of remote effect frosting are followed effect.
(3) thermotolerance: the static inhibitor of low heat-resistant quality is adding man-hour, decomposes easily or volatilization and can't produce hundred-percent antistatic effect.
(4) temperature dependency: because that anlistatig conductive mechanism is subject to balance moisture content impact is very large, so effect can descend under the environment of low temperature.
(5) late effect property: in the occasion of inner moulding, the goods of just moulding need just to have anlistatig effect more than 1 to 3 day.
(6) physical properties impact: the higher macromolecular compound of glass transition temp at room temperature, its molecular chain is frozen state, static inhibitor is difficult for migrating to the surface, otherwise the lower macromolecular compound of glass transition temp at room temperature, can allow static inhibitor to make fast transferring, and reach the achievement of prompt effect.
Therefore, select suitable static inhibitor to be added in the anlistatig article, and propose a kind of can effective anlistatig article, prevent the harm that static discharge brings, improve that the yield of product is real to belong to necessary.
Summary of the invention
The invention reside in manufacture method and structure thereof that antistatic rubber is provided, mainly for existing information, electronics and semiconductor industry, or need to use the industry of antistatic material, a kind of effective anlistatig rubber material is proposed, can reduce the harm that static discharge brings these industries, the yield of improving product.
The present invention proposes a kind of manufacture method of antistatic rubber, and it may further comprise the steps: a base cloth is provided; The coating thickener is on the surface of this base cloth, and this base cloth of heating, drying forms one and sticks with paste cloth; Make the compound sizing material of polyvinyl chloride and thermoplastic poly ammonia (amine) carbamate, this compound sizing material comprises interpolation one static inhibitor; This compound sizing material is processed to form an adhesive plaster; And fit this paste cloth and this adhesive plaster.
The present invention proposes a kind of structure of antistatic rubber in addition, and it comprises: one sticks with paste cloth, and this paste cloth comprises a base cloth and thickener; And an adhesive plaster, this adhesive plaster comprises polyvinyl chloride and thermoplastic polyurethanes matrix material and a static inhibitor, this adhesive plaster and this paste cloth are bonded with each other.
For enabling further to understand feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, yet appended graphic only provide with reference to and explanation usefulness, be not to the present invention's limitr in addition.
