Description
Technical field
The present invention is about substrate, especially with regard to a kind of preparation method of bright enhancement film transparent substrates.
Background technique
Bright enhancement film category optical diffusion is the significant components of organic flexible screen, and traditional raw material for preparing is industrial chemicals,
Price is high and development is unsustainable.In view of flexible screen the relevant technologies as a new technology, be expected to apply on a large scale mobile phone,
On the high-tech products such as LCD TV, computer, automobile and wearable smart machine.The technical research of Related product has tempting
The prospect of marketing.
The material for preparing of traditional optical diffusion barrier such as bright enhancement film mainly includes polymethyl methacrylate (PMMA), gathers to benzene
Dioctyl phthalate second diester (PET), polybutyl methacrylate (PBMA) and polyurethane (PU) etc..The main original that above-mentioned material is selected
Because being them with high visible light transmittance, but in cost of material, thermal stability, tensile strength, resisting etiolation, size variation
Still have much room for improvement with adhesion strength etc..In addition, these materials belong to chemical plastic, production cost is fluctuated shadow by crude oil price
It rings greatly, market stability is poor.It of particular concern is, these materials are existed with micron order film or microspheres form, are easily produced
The ecological environment problems such as raw " micro- plastics ", " white pollution ", or even directly threaten human health, it is therefore necessary to develop one
The more excellent and economic and environment-friendly optical diffusion new material of kind performance.
Bio-based materials refer to a kind of new material manufactured using renewable biomass, the renewable, cost with raw material
The characteristics such as cheap, safety non-pollution, biodegradable.Chitin nano fiber material is one kind that fast development is got up in recent years
Bio-based materials become with high transparency (> 90%), big tensile strength (> 230MPa), the size that thermal stability is good, excellent
Many advantages, such as anisotropic and resisting etiolation, extremely meet requirement of the optical diffusion to material is prepared.In addition, addition chitin is received
Rice fibrous material is also remarkably improved the adhesion strength of the binders such as PU.It of particular concern is, chitin is produced in nature
Amount is only second to the second largest natural polymer of cellulose, and preparing raw material is mainly shrimp and crab shells, and China has this of very abundant
Class cheap raw material.To sum up, if performance may be prepared with traditional chemical plastic such as chitin nano fiber material substitution PET
More preferably, price is lower and the optical diffusion of safety non-pollution.
