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 protecting film and preparation method thereof.
Background technology
As everyone knows, the radiation of low frequency is arranged before the computer screen, people can cause people's visual fatigue, even cause myopia for a long time in the face of computer screen the time.The computer protecting film of being sold in the market mainly is in order to prevent that LCD screen from scratching or collision cleft, prevent dust and the scratch resistance performance though have preferably that it does not have radiation proof function.In addition, these computer protecting films are high molecular polymerization films such as synthetic PE for preparing of petrochemical industry material and PVDC mostly, exist problems such as consumes energy, contaminated environment.Therefore, develop that a kind of technology is simple, with low cost, the radiation proof computer protecting film of energy-conserving and environment-protective has become the new development trend of computer protecting 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 with anti-reflection, antistatic, anti-electromagnetic-radiation film; Through utilizing the anti-reflection performance and the electric conductivity of metal and combination of media; Thereby can reduce production cost without traditional I TO nesa coating.Simultaneously, adopt common vacuum evaporation, be convenient to produce.Therefore, have market prospects and using value preferably.But in the process of being coated with, how baseplate material reels, and becomes the technological problems of the large-scale production of this radioresistance film of restriction.
" Chinese rare-earth journal " December in 2002 the 6th phase Zhang Ming article " preparation of rare earth modified PVC film and performance study ", be employed in the PVC material and add rare earth compound and prepare anti-aging, the radiation prevention film of PVC.The PVC film of preparation is infrared all to be improved with uv absorption.But because rare earth compound is main with powder, be difficult for evenly disperseing, certain influence 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 protecting film and preparation method thereof, because of watching computer screen for a long time, receive the electron radiation of computer and produce fatigue or cause myopia in order to the eyes that prevent people.
The preparation method of a kind of radiation proof computer protecting film of the present invention is characterized in that operating procedure is following:
(1) preparation of film liquid: get 1L water and be heated to 70 ~ 80 ℃; Adding mass percent in the water after the heating then is that 1% ~ 2% purity is 99.8% titanium dioxide; Mass percent is that 0.5% ~ 1% purity is 99.9% zinc oxide; NaOH solution adjust pH to 7.5 ~ 11 with 1mol/L; And place on the agitator 70 ~ 80 ℃ of constant temperature to stir 0.5h ~ 1h; Rotating speed is 1200r/min; Add purity while stirring and be konjaku flour 6 ~ 7g of 95%; Purity is carragheen 4 ~ 5g of 99.9%; Purity is xanthans 1 ~ 2g of 80%; Constant temperature leaves standstill 50 ~ 60min under 40 ~ 50 ℃ condition then; Process film liquid, subsequent use;
(2) moulding of film: the film liquid of step (1) preparation is placed the centrifuge of the 3000r/min 30min that outgases, inject then in the mould, scrape off unnecessary film liquid and smear evenly with glass rod;
(3) oven dry of film: the film liquid that will inject mould places 50 ~ 70 ℃ drying baker to dry film forming together with mould, 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 the packing.
The preparation method of a kind of radiation proof computer protecting film of the present invention, the radiation proof characteristic of utilizing good filming performance that konjaku flour has and compounds such as titanium oxide, zinc oxide to have, preparation radiation proof computer protecting 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 well anti-machinery; Also having degradable advantage simultaneously, is a kind of product of environmental protection.
The specific embodiment
In order fully to disclose a kind of radiation proof computer protecting film of the present invention and preparation method thereof, illustrate below in conjunction with embodiment.
Embodiment: a kind of preparation method of radiation proof computer protecting film may further comprise the steps:
(1) preparation of film liquid: get 1L water and be heated to 75 ℃; Add mass percent then in the water after the heating and be 1.2% titanium dioxide and 0.8% zinc oxide; And with the NaOH solution adjust pH to 9 of 1mol/L; And place on the agitator 75 ℃ of constant temperature to stir 40min; Rotating speed is 1200r/min, adds konjaku flour 6g, carragheen 4g, xanthans 1.2g while stirring, and constant temperature leaves standstill 50min under 45 ℃ condition then; Process film liquid, subsequent use;
(2) moulding of film: the film liquid of step (1) preparation is placed the centrifuge of the 3000r/min 30min that outgases, remove the gas that exists in the film liquid; And by the suitable mould of requirement of products selection, the film liquid after the degassing is injected in the mould, scrape off unnecessary film liquid with glass rod, smear evenly, it is level and smooth to make it any surface finish;
(3) oven dry of film: the film liquid that will inject mould places 60 ℃ drying baker to dry film forming together with mould, then with the film lift-off stencil;
