Description
Technical Field
The invention relates to the technical field of polyester films, in particular to an antistatic polyester film with surface enriched conductive TiO 2 obtained by an interface suspension method and a preparation method thereof.
Background
Polyester films such as polyethylene terephthalate (PET) films have good comprehensive properties and are widely applied to the fields of electronics, optics and the like. However, the polyester film is used as a polymer insulating material, has higher self-resistivity, is easy to generate static electricity due to friction in the production and use processes, brings a plurality of inconveniences to the application of the polyester film, and particularly leads to the failure of a semiconductor due to the electrostatic discharge phenomenon when the polyester film is applied to the field of electronic and electric appliances, thereby influencing the performance of products. Therefore, the antistatic modification of the polyester film has very important practical significance.
The conductive TiO 2 is used as a conductive filler with high whiteness and good antistatic effect, and can reduce the influence on the color of the product while reducing the surface resistance of the insulating material. In addition, the traditional antistatic modification method is easy to cause embedding of the conductive filler, thereby influencing the antistatic effect of the material, improving the utilization rate of the conductive filler, and realizing single-sided aggregation of the conductive filler has very important application value.
Disclosure of Invention
The invention aims to break the bottleneck of the prior art scheme and improve the utilization rate of conductive filler, so as to obtain a polyester film (conductive TiO2@SEBS/PET film) with excellent antistatic performance.
The technical scheme for solving the technical problems is as follows:
a method for preparing an antistatic polyester film, comprising the following steps:
firstly, adding a toluene solution of SEBS and absolute ethyl alcohol into a beaker, adding a stirrer, placing the stirrer on a magnetic stirrer, starting the stirrer, adding conductive TiO 2, and uniformly stirring to obtain a mixed solution of SEBS/conductive TiO 2/absolute ethyl alcohol/toluene;
Sucking the SEBS/conductive TiO 2/absolute ethyl alcohol/toluene mixed solution by a liquid-transfering device, slowly dripping the SEBS/conductive TiO 2/absolute ethyl alcohol/toluene mixed solution into a glass vessel filled with deionized water, and stopping dripping after the white solution is paved on the water surface;
Placing the surface dish at a position with stable wind speed until toluene is mostly volatilized, covering the solution surface with a polyester film (such as a PET film, and other polyester films can be used as well) with the surface cleaned by ethanol, and placing the surface dish in a ventilation channel after the conductive film is completely adhered to the polyester film, and obtaining the antistatic polyester film with the conductive layer adhered to the surface after toluene is completely volatilized.
Preferably, the toluene solution of SEBS is prepared as follows: weighing 500mL of toluene corresponding to each 40gSEBS parts of SEBS and toluene, adding all toluene into a reagent bottle, then placing into a stirrer, placing the reagent bottle on a magnetic stirrer, opening the magnetic stirrer, adding SEBS powder for 5 times, adding all SEBS powder, covering the reagent bottle, and taking out the stirrer after stirring until the SEBS is completely dissolved to obtain the toluene solution of the SEBS.
Preferably, the volume ratio of the absolute ethyl alcohol to the toluene solution of the SEBS is 1:3-4.
Preferably, the ratio of the addition amount of the conductive TiO 2 to the toluene solution of the SEBS is that 0.833mg-20mg of TiO 2 is added to 1.1 mLSEBS of toluene solution.
Preferably, the volume of SEBS/conductive TiO 2/absolute ethanol/toluene mixed solution sucked by a pipette is 1mL of mixed solution corresponding to 25-30 square centimeters of water surface area relative to the deionized water surface area in the glassware.
The method comprises the core processes of mixing conductive TiO 2 with SEBS toluene solution, adding ethanol, dripping on the surface of deionized water, and generating a Marangoni effect (Marangoni effect) by utilizing the difference of surface tension, wherein the dissolution of ethanol in water can reduce the local surface tension, so that a round surface tension gradient is formed near the liquid drop. This gradient causes the Marangoni effect to flow from the center to the boundary, dragging floats including toluene, SEBS, and conductive TiO 2. Along with the diffusion of ethanol, the boundary is expanded, so that the solution is paved on a water interface, meanwhile, by reducing the interface energy between water-ethanol and toluene-SEBS, conductive TiO 2 exists in the interface between the mixed solution and deionized water, along with the volatilization of toluene, an SEBS film with conductive TiO 2 at the bottom is left on the water surface, and then the SEBS film is compounded with a polyester film matrix, so that the antistatic PET film with the surface enriched with conductive TiO2 is finally obtained. As shown in the cross-section SEM (fig. 1a and 1 b) and the surface SEM (fig. 1c and 1 d) of the film in fig. 1, the method of the invention can lead the conductive TiO 2 to be mainly present on the surface of the PET film, and lead the conductive TiO 2 to form a communication network on the surface of the film as much as possible, thereby greatly reducing the surface resistance of the film surface, improving the utilization rate of conductive substances and being beneficial to reducing the production cost.
The invention has the beneficial effects that: the conductive TiO2 can be orderly arranged at the interface layer of toluene and water by an interface suspension method, and is gathered at one side of the water phase by utilizing the hydrophilicity of the conductive titanium dioxide; along with the volatilization of toluene, the conductive titanium dioxide can form good adhesion with the PET film through SEBS, so that the conductive TiO2 can be enriched on the outer surface of one side of the polyester film to form a relatively compact and communicated electrostatic conduction layer, and the utilization rate of conductive substances is greatly improved. In addition, the surface hydrophilicity of the antistatic PET film is greatly improved by the suspension interface modification, and the surface contact angle is reduced to 25 degrees. The polyester film prepared by the method has excellent antistatic performance.
