Abstract
The invention discloses a preparation technology for uvioresistant modified PET film coating liquid, which is characterized by comprising the following steps of: 1, preparing 15-50wt.% of conducting polymer resin, 15-50wt.% of silane coupling agent, 20-55wt.% of vinyl organic silicon resin, 0.1-2.0wt.% of glycerin, 0.05-1.0wt.% of antioxygen, 0.1-1wt.% of calcium stearate and 30-40wt.% of ultraviolet light absorber into slurry, wherein the ultraviolet light absorber is chlorinated benzotriazole type ultraviolet light absorber; 2, heating slurry in the step 1, wherein the heating temperature is 80-120 DEG C and the heating time is 10-30S. According to the preparation technology, the formula is improved, and the problem that in the prior art the PET film is colored that the visual effect is influenced is solved by adopting the method of mixing the ultraviolet light absorber with the PET functional layer master batch and then heating to melt.
Description
Technical field
The present invention relates to a kind of preparation technology of uvioresistant modified PET film coating fluid.
Background technology
PET release film is exactly take PET film as base material, and is coated with last layer silicone oil on the surface of PET film, makes the surface of PET film sliding, to reduce the tension force on PET film surface.Reach release effect.
PET release film is a kind of material that hot transfer printing is commonly used, and ground is PET, forms so be also silicon oil membrane through coating silicone oil.General thickness is from 25um to 150um.Have cold and hot to tear with light mute point, through anti-electrostatic and anti-scratch process, product has good adsorptivity and stickiness.
The industry fields such as PET release film now extensively should be packed, print, silk-screen, bat printing, inscription plate, thin film switch, flexible circuitry, insulated product, wiring board, laser anti-counterfeit, laminating, electronics, sealing material use film, light reflecting material, water-proof material, medicine (plaster paper using), sanitary paper, adhesive article, the processing of cross cutting stamp.The materials such as plastics, glass, metal transport and use procedure in, its surface be easily subject to contact pollution or cut, break equivalent damage, so usually need use wrapping material parcel or cover its surface, make its from pollution and damage.These need the material of protection as plastics etc., are easy to be subject to ultraviolet destruction, need to use the packaging protecting material with anti-ultraviolet function.
It is light that PET release film has quality, shock resistance and the transparency good, with indeformable when hot water and caustic soln carrying out washing treatment and keep transparent advantage.The surface of PET release film applies one deck coating fluid usually, reaches waterproof and barrier property, and the coating fluid of prior art does not have anti-ultraviolet function, creates certain influence to the application of release film.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, provides a kind of preparation technology of uvioresistant modified PET film coating fluid.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The preparation technology of a kind of uvioresistant modified PET of the present invention film coating fluid, is characterized in that, comprise the following steps:
