Abstract
A diffusion film mainly consists of a pure optical PET film and a particle elastomer film. The diffusion film is characterized in that the pure optical PET film and the particle elastomer film are fixedly adhered. The diffusion film adopts the abovementioned structure, and the structure is simple and elegant, and has energy-saving and environment-friendly functions.
Description
Technical field
The utility model relates to a kind of appliance and electronic, is specifically related to a kind of diffusion barrier.
Background technology
Nowadays the diffusion barrier in LCD shows generally is to be coated with at the PET of optical grade film to be covered with particulate and to form, various chemical solvents in manufacture process, have been used, workman healthy brought threat, and it is poor to be coated with the particulate scratch resistance that is covered with, in the cutting process, easily come off, cause the raising of fraction defective, increased cost.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of diffusion barrier, on the basis that possesses former diffusion barrier function, also has the function of certain energy-conserving and environment-protective.
The utility model is to be able to by the following technical programs reality: a kind of diffusion barrier, mainly formed by pure optics level PET film and particulate elastomer film, and it is characterized in that: pure optics level PET film and the fixedly adhesion of particulate elastomer film.The utility model has solved the problem of health threat effectively, has saved to apply this technique, has reduced cost, more energy-conserving and environment-protective.
Described particulate elastomer film is that pure optics level PET is placed in the extruder and extrudes, and extrudes in addition the elastomer film TPE that is mixed with the diffusion particulate in the two extruders, extrudes casting film, and two-way stretch forms again.Wherein TPE is thermoplastic elastomer, and as a kind of new material, TPE had both had the processing characteristics of thermoplastics, processing characteristics is superior, need not vulcanize, and can recycle the reduction cost, both can secondary injection molding, with PP, PE, PC, PS, the matrix material coating and bondings such as ABS, also separately moulding has again the physical property of vulcanized rubber, high resiliency, high strength, high resilience is the advantage combination of plastics and rubber advantage, durometer level is wide, good coloring is arranged, soft-touch, weatherability, fatigue resistence and temperature tolerance, anti-slip type, and have environment-protecting asepsis safety, harmless, at high temperature, easy-formation, and stay in grade have processing simply, molding cycle is short, production efficiency is high, light specific gravity, materials are economized, waste material is recyclable, free of contamination advantage.
The beneficial effects of the utility model are: adopt said structure, this is simple in structure generous, has the function of energy-conserving and environment-protective.
Description of drawings
