(2) prepare poly-vinyl alcohol solution, described poly-vinyl alcohol solution comprises 50 ~ 60% silica and 20 ~ 30% aluminium oxide by mass percentage;
(3) poly-vinyl alcohol solution that described step (2) obtains is coated on the substrate after described step (1) coating, after oven dry, obtains finished product film.
The modified poly ester slurries adopted in preparation method of the present invention are: by bishydroxyethyl terephthalate oligomer and excessive ethylene glycol polymerisation, catalyst is antimony oxide, in course of reaction, add fluorinated silicone modified dose again.Wherein, described antimony oxide accounts for 0.01% of bishydroxyethyl terephthalate oligomer quality; Described fluorinated silicone modified dose accounts for 8 ~ 18% of bishydroxyethyl terephthalate oligomer quality.The coating being later step by coated on both sides modified poly ester solution provides condition, thus improves original PET heat resistance, insulating properties and slickness.
In described step (2), the degree of polymerization of polyvinyl alcohol is 3000, and alcoholysis degree is 85%.Poly-vinyl alcohol solution of the present invention will ensure certain viscosity, thus can closely be coated in other coatings, and higher alcoholysis degree can improve the affinity of this coating and other hydrophobic coatings simultaneously.Silica in step (2) is nanometer grade silica dispersion soln; Aluminium oxide is nano-alumina powder.
80 ~ 95 DEG C of oven dry after the middle painting polyethylene alcoholic solution of described step (3).
Beneficial effect: a kind of MPET ULTRASONIC P ACS medical diagnosis report film face roughness of the present invention is 0.08 ~ 0.16, and coefficient of friction is about 0.4, and surface gloss reaches 80%, and light transmittance is 30%, and tensile strength is 120N.This film is mainly used in inkjet printing, the precision of medical imaging can be increased substantially, the resolution ratio of inkjet printing can up to 5760 × 1440dpi, eliminate laser printing to give up powder box and toner cartridge pollution on the environment, glossiness, light transmittance all reach the requirement of medical film, antistatic, crease-resistant wear-resisting, coating does not come off, and available common water borne signature pen is write on film.The method for making of this film is also improved for required product performance, ensure that each coating is closely linked, is not easy to peel off, and makes the combination property of composite coating be improved simultaneously.
