Abstract
The invention provides a preparation method for antistatic optical spherical hood made from polycarbonate, which is characterized in that: based on the PEDOT-PSS aqueous solution, right amounts of pH regulator, adhesive, PSS cross-bonding agent, distilled water, organic solvent, and impregnating agent are applied to prepare membrane forming solution, and the membrane forming solution is then coated on the polycarbonate spherical hood. The preparation method for antistatic optical spherical hood made from polycarbonate has the advantages that: the transparency and the permanent antistatic performance are excellent without being affected by the air humidity, and the antistatic films are unlikely to be dissolved in any solvent; since only post treatment is carried out for minutes and no surface treatment is adopted for outer surfaces of the made optical spherical hood, the technique is simple, the cost is low, and no alternation is needed for the prior process equipment; since the raw materials are nonpoisonous and harmless and no toxic elements are detected by chemical analysis, and thus meeting the environmental requirements.
Description
Technical field
The invention belongs to chemical field, more specifically relate to a kind of preparation method of polycarbonate anti-static optical ball cover.
Background technology
Polycarbonate (PC) is because its excellent mechanical property and outstanding light transmission are widely used in optical instrument field.But because the surface resistivity of these two kinds of materials is too high (greater than 10
15Ω), when friction took place, material surface was understood stored charge and is brought many adverse consequencess.For example, unnecessary static charge can attract dust, makes the light transmission of optics significantly reduce.
Because the mold temperature of polycarbonate is very high in the actual production, traditional antistatic method treatment process can not be used to prepare the transparent PC material with permanent antistatic performance.Therefore, how research prepares anti-transparent antistatic polycarbonate products and is significant.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of polycarbonate anti-static optical ball cover; This preparation technology is simple, needn't change original process equipment, as long as after making optical ball cover, the aftertreatment several minutes gets final product, and the outside surface of ball cover need not carry out any surface treatment; Product transparent good of preparation, antistatic property excellence and be permanent; Resulting antistatic film is insoluble to any solvent; Cost is low, and overall economic efficiency is remarkable; Compliance with environmental protection requirements.
The preparation method of polycarbonate anti-static optical ball cover of the present invention is characterized in that: described preparation process is:
(1) injection moulding optical ball cover: be under 70 ℃～90 ℃ the condition, in temperature with the polycarbonate pellet oven dry, by the injection moulding machine injection moulding;
(2) configuration generates the solution of transparent conductive film: according to mass ratio, to gather (3,4-enedioxy thiophene) the PEDOT-polystyrolsulfon acid PSS aqueous solution or polystyrolsulfon acid place the container that has agitator for 1 part, at 5～10 parts of the organic solvents, 0.02 part of the treating compound that continue to add 0.02～0.06 part of pH value conditioning agent, 3～5 parts in tackiness agent, 0.01 part of PSS linking agent, 3～5 parts of distilled water under the stirring successively, improve film forming speed, continue to stir 0.5～3h, make film forming liquid;
(3) generate conductive film at the optical ball cover extexine: at room temperature, the film forming liquid that step (2) is made is coated in the extexine of the optical ball cover of step (1) preparation, then ball cover is placed baking oven to dry 5-20min down, obtain the optical ball cover of transparent antistatic after the drying at 70 ℃～100 ℃.Advantage of the present invention has:
(1) the present invention utilizes antistatic principle: why insulating material can play static on the surface, is because its surface resistivity is too big, to such an extent as to when friction took place, the static charge of Chan Shenging can not leave thereupon.The principle of this antistatic method is the macromolecule membrane that forms one deck conduction at the outside surface of ball cover, forms the electric charge fire escape, thereby plays anlistatig effect.In the use, the surface resistivity of material can be according to the amount control that adds Baytron P, and Baytron P add-on multilist face resistance more is low more, and antistatic effect is good more, but the transparency can be poor more; The few more transparency of Baytron P adding is good more, but surface resistivity is high more.Owing to can form the conductive polymer film of layer of transparent after the solvent evaporates at the ball cover outside surface, this film has good static resistance, light transmission, stability, the weather resisteant of getting, and therefore, product can must place the open air over a long time, superficial film can not come off, and has persistent antistatic property.
(2) product is transparent good, the antistatic property excellence; The antistatic property of material is not subjected to the influence of atmospheric moisture; Resulting antistatic property is permanent; Resulting antistatic film is insoluble to any solvent.
(3) cost is low, and overall economic efficiency is remarkable.
(4) compliance with environmental protection requirements.Starting material are nontoxic, through chemical analysis, find no malicious element and exist.
(5) technology is simple, needn't change original process equipment, as long as after making optical ball cover, the aftertreatment several minutes gets final product, and the outside surface of ball cover need not carry out any surface treatment.
