Abstract
The invention relates to a preparation method of a radiation proof computer protection film. The preparation method comprises steps of film liquid preparation, film molding, film drying, and film cutting. According to the preparation method of the radiation proof computer protection film, the radiation proof computer protection film is prepared from konjak powder which has excellent film forming performances and compounds of titanium oxide, zinc oxide and the like which have a radiation proof characteristic, so above technology is simple and the cost is low; the radiation proof computer protection film has the characteristics of smooth surface and high light transmittance, and has a good mechanical scratch resistance and a good radiation proof performance; and the radiation proof computer protection film which has a degradable advantage is an environmentally friendly product.
Description
Technical field
The present invention relates to a kind of diaphragm and preparation method thereof, be specifically related to a kind of radiation-resistant computer protection film and preparation method thereof.
Background technology
As everyone knows, the radiation of low frequency is arranged before computer screen, people can cause people's visual fatigue for a long time in the face of computer screen the time, even cause myopia.The computer protection film of selling in the market is mainly in order to prevent that LCD screen from scratching or collision cleft, although have dustproof and adhesion strength preferably, it does not have radiation proof function.In addition, these computer protection films are the high molecular polymerization films such as the synthetic PE for preparing of petrochemical industry material and PVDC mostly, exist problems such as consuming the energy, contaminated environment.Therefore, simple, with low cost, radiation proof computer protection films energy-conserving and environment-protective of a kind of technique of development have become the new development trend of computer protection film industry.
The article of " optical technology " calendar year 2001 the 5th phase Li Fang " development of anti-reflection, antistatic, anti-electromagnetic-radiation film ", the method that employing includes layer of metal is coated with CMT anti-reflection, antistatic, anti-electromagnetic-radiation film, by utilizing anti-reflection performance and the electric conductivity of metal and combination of media, thereby ITO nesa coating that can be traditional has reduced production cost.Simultaneously, adopt common vacuum evaporation, be convenient to produce.Therefore, have market prospects and using value preferably.But in being coated with process, how baseplate material reels, and becomes the technological problems of the large-scale production of this radioresistance film of restriction.
" China rare earth journal " December in 2002 the 6th phase Zhang Ming the article preparation and property of the PVC Film Modified by Rare Earth " research ", adopt and add rare earth compound prepare that PVC is anti-aging, radiation prevention film in the PVC material.The PVC film of preparation is infrared all to be improved with UV absorption.But take powder as main, be difficult for Uniform Dispersion due to rare earth compound, certain impact can be arranged the UV absorption of PVC film.
Summary of the invention
The purpose of this invention is to provide a kind of radiation proof computer protection film and preparation method thereof,, be subject to the electron radiation of computer and produce fatigue or cause myopia because watching for a long time computer screen in order to the eyes that prevent people.
The objective of the invention is to be achieved through the following technical solutions:
The preparation method of a kind of radiation proof computer protection film of the present invention comprises the preparation of film liquid, the moulding of film, the oven dry of film and the cutting of film, it is characterized in that operating procedure is as follows:
(1) preparation of film liquid: get 1L water and be heated to 70 ~ 80 ℃, then in the water after the heating to add mass percent be that 1% ~ 2% purity is 99.8% titanium dioxide, mass percent is that 0.5% ~ 1% purity is 99.9% zinc oxide, with the NaOH solution adjust pH to 7.5 of 1mol/L ~ 11, and be placed on agitator 70 ~ 80 ℃ of constant temperature and stir 0.5h ~ 1h, rotating speed is 1200r/min, adding while stirring purity is konjaku flour 6 ~ 7g of 95%, purity is carragheen 4 ~ 5g of 99.9%, purity is xanthans 1 ~ 2g of 80%, then the standing 50 ~ 60min of constant temperature under the condition of 40 ~ 50 ℃, make film liquid, standby,
(2) moulding of film: the film liquid of step (1) preparation is placed in the degassed 30min of centrifuge of 3000r/min, then injects in mould, scrape off unnecessary film liquid and smear evenly with glass rod;
(3) oven dry of film: the film liquid that will inject mould is placed in the drying baker of 50 ~ 70 ℃ together with mould and dries film forming, then with the film lift-off stencil;
(4) cutting of film: the film of peeling off is cut into different sizes on demand, is finished product after packing.
The preparation method of a kind of radiation proof computer protection film of the present invention, the radiation proof characteristic of utilizing good filming performance that konjaku flour has and the compounds such as titanium oxide, zinc oxide to have, the preparation radiation proof computer protection film, manufacture craft is simple, with low cost; Product has smooth surface, characteristics that light transmittance is high, scratches and shielding property but also have good anti-machinery; Also having simultaneously degradable advantage, is a kind of product of environmental protection.
Specific embodiment
In order fully to disclose a kind of radiation proof computer protection film of the present invention and preparation method thereof, be illustrated below in conjunction with embodiment.
Embodiment: a kind of preparation method of radiation proof computer protection film comprises the following steps:
(1) preparation of film liquid: get 1L water and be heated to 75 ℃, then adding mass percent in the water after the heating is 1.2% titanium dioxide and 0.8% zinc oxide, and with the NaOH solution adjust pH to 9 of 1mol/L, and be placed on agitator 75 ℃ of constant temperature and stir 40min, rotating speed is 1200r/min, adds while stirring konjaku flour 6g, carragheen 4g, xanthans 1.2g, then the standing 50min of constant temperature under the condition of 45 ℃, make film liquid, standby;
(2) moulding of film: the film liquid of step (1) preparation is placed in the degassed 30min of centrifuge of 3000r/min, removes the gas that exists in film liquid; And select suitable mould by the requirement of product, and the film liquid after degassed is injected in mould, scrape off unnecessary film liquid with glass rod, smear evenly, make it any surface finish level and smooth;
