Abstract

The invention relates to hot-press-free antibacterial and anti-scraping optical explosion-proof film. Konjac glucomannan nanocrystalline is added into a protection layer and modified through chitosan,the interfacial interaction force among molecules in a formula system is greatly increased, the dispersing performance and the compatibility among components are improved, and thus the mechanical performance of the structure of the protection layer is improved; by adding inorganic and organic compound synergistic antibacterial agents, the antibacterial effect of the protection layer is greatly improved, and cross propagation of bacteria after surface contact of the human body is avoided; the antibacterial and anti-scraping optical explosion-proof film is subjected to hot-press-free curing molding, and the processing procedure and the processing cost are reduced; TPU is good in processability and flexibility and resistant to shock, an optical-grade PET base material is good in optical transparency, the requirement of the explosion-proof film for the optical performance is met, and the light transmittance of the explosion-proof film is increased. The explosion-proof film has good lighttransmittance, static resistance, wear resistance, scraping resistance and bacterial resistance; through the arrangement of the explosion-proof structure layer, the safety and stability during use areguaranteed, and meanwhile the requirement for optical-grade appearance is met.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof membranes, and relates to a heat-free antibacterial, anti-scratch, optical explosion-proof membrane. Background technique [0002] Explosion-proof film is a protective film installed on the display screen of digital electronic products, automotive industrial control display, car front windshield, and industrial industrial control display to protect the display screen or glass. With the development of touch screen technology and market for electronic products, various explosion-proof films on the outer surface of the touch screen have appeared on the market. The explosion-proof film can prevent the touch screen from being broken due to external impact and cause fragments to fly, which can meet the needs of consumers. However, the explosion-proof membranes currently on the market usually have poor or no antibacterial properties, insufficient scratch and wear resistance, and low service life;...
