Zusammenfassung:The invention discloses a preparation method of a special material for enhancing the fingerprint (palm print) collecting effect of a living fingerprint (palm print) collecting instrument. According to the preparation method, high-molecular compound methyl block room temperature vulcanized silicon rubber and PET are taken as main materials, the methyl block room temperature vulcanized silicon rubber is uniformly spread onto a PET release layer material, then is placed into an electronic damp-proof cabinet and is vulcanized to form a reinforced membrane which is covered with a PET stripped layer material after being completely dried, and then slitting, checking and packaging are carried out. The thickness of the reinforced membrane is 0.5mm, thus the reinforced membrane has strong adsorption capability, can be well adsorbed to the surface of glass of the fingerprint (palm print) collecting instrument, and has relatively high light transmittance and relatively strong anti-tension strength. By adopting the preparation method of the special material for enhancing the fingerprint (palm print) collecting effect of the living fingerprint (palm print) collecting instrument, the special material prepared by the method can be used for effectively eliminating the influence of dry finger and shallow fingerprint (palm print) lines on images of fingerprint (palm print), increasing the fingerprint (palm print) collecting passing rate, and protecting the glass of a collecting window of the fingerprint (palm print) collecting instrument.
