Abstract
The invention relates to a bactericidal polycarbonate fluorescent thin film and belongs to the field of macromolecular materials. The fluorescent thin film is characterized by comprising the following raw materials in parts by weight: 100 to 120 parts of polycarbonate, 0.05 to 0.8 part of antioxidant, 3 to 6 parts of monostearin, 5 to 10 parts of rare-earth aluminate fluorescent powder, 0.1 to 0.5 part of tea tree oil, 2 to 5 parts of barium-zinc stabilizer, and 0.5 to 1.1 parts of release agent. The fluorescent thin film keeps the advantages of the prior art and has a good antistatic effect; by using the light-induced energy storing fluorescent powder, the fluorescent thin film has the property of fluorescence and does not have harm to human bodies; and by adding the tea tree oil serving as a natural bactericidal material, the fluorescent thin film has a good sterilization function and does not have any side effect. Moreover, the fluorescent thin film is wide in application range and is particularly suitable for making various keyboard films.
Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of sterilization polycarbonate fluorescence membrane.
Background technology
Used fluorescent material is generally and has radioactive luminescent powder in the market, the rays excite light-emitting phosphor that utilizes radioactive substance constantly to send, and this class luminescent powder fluorescent lifetime is very long, but ranges of application such as poisonous and harmful and environmental pollution are little.Though some products use the noctilucent material as matrix with ZnS, have only 1～3 hour its time of persistence, while blackout apt to deteriorate in high light, UV-light and damp atmosphere, and therefore middle the application is restricted in a lot of fields.
Polycarbonate is called for short PC, be one of five big general engineering plastic, the polycarbonate film transmittance can 90%, mist degree＜0.2%, the heat decomposition temperature height, have excellent electric insulation, be widely used in numerous areas such as machinery, automobile, space flight and aviation, building, electronics, electric, office and household supplies.
At present, when many people use computer or other plant and instrument at night, under the faint condition of no light source or light source, can't use equipment effectively.Because polycarbonate film is easily bonding, easily printing, therefore good moldability can be used to make various keyboard membranes.Chinese patent 201210524351.3, though proposed a kind of fluorescent polycarbonate keyboard membrane, it does not have antistatic property, and simultaneously, the nano titanium oxide that it uses is as sterilant, and its photocatalysis meeting damages HUMAN HEALTH.
Therefore, how to overcome the deficiencies in the prior art, produce a kind of polycarbonate fluorescence membrane, it not only has fluorescent effect, can also be effectively antistatic, and have the natural disinfection function, be the problem that present field of polymer technology is needed solution badly.
Summary of the invention
The objective of the invention is in order to solve the deficiencies in the prior art, a kind of sterilization polycarbonate fluorescence membrane is provided, product of the present invention not only has fluorescent effect, and effectively antistatic, sterilization can be used for making various keyboard membranes etc.
The technical solution used in the present invention is as follows:
A kind of sterilization polycarbonate fluorescence membrane is characterized in that comprising the following raw material according to the parts by weight meter: 100 ~ 120 parts of polycarbonate, 0.05 ~ 0.8 part in oxidation inhibitor, 3 ~ 6 parts of Tegin 55Gs, 5 ~ 10 parts of rare earth aluminate luminescent powders, 0.1 ~ 0.5 part of tea tree oil, 2 ~ 5 parts of barium zinc stabilizers, 0.5 ~ 1.1 part of releasing agent.
Further, its prioritization scheme is that described oxidation inhibitor is oxidation inhibitor 164.
Preparation method of the present invention: at first the raw material with aforementioned proportion mixes in high-speed mixer, the material that mixes is put into the dual-screw-stem machine melt blending to be extruded, pelletizing after being the warm water cooling is put into extrusion equipment film processed with the gained particle, namely.
The present invention compared with prior art, its beneficial effect is:(1) product of the present invention has good antistatic property, and has used the photo-induced energy storage luminescent powder on the advantage that keeps prior art, makes this product have fluorescent characteristic, and human body is not had injury; (2) add natural disinfection material---tea tree oil, made this product have good sterilizing function, without any side effects; (3) application range of products of the present invention is wider, is particularly suitable for making various keyboard membranes.
