Problems solved by technology

Because general organic polymer materials have the advantages of simple production, easy processing and molding, high transparency, and low cost, but also have disadvantages such as poor weather resistance and weak functionality; while inorganic materials have good temperature resistance and multi-function (anti-static, anti-ultraviolet) , anti-fouling, anti-static) and other advantages, but the disadvantage is that it is not easy to process and shape, especially the shortcomings of non-geometric rules that are difficult to process restrict its large-scale use in daily life
Therefore, a single material restricts the application of organic materials and inorganic materials in the process of industrial upgrading

Abstract

The invention discloses a method for preparing a hardened and wear-resistant optical thin film through one-step co-extrusion stretching. The method comprises the following steps: (1), preparing inorganic nano powder with hardening and wear-resistant functions into nano color paste with good dispersibility; (2) stirring the nano color paste with good dispersibility and hardening and wear-resistant functions with organic plastic master batches for 10-15 minutes by virtue of double screws at the temperature of 280-285 DEG C, then extruding and granulating, so that the plastic particles with the hardening and wear-resistant functions are obtained; and (3) in a process of preparing the hardened and wear-resistant optical thin film, adding not more than 20% of the plastic particles with the hardening and wear-resistant functions, so that the optical thin film with the hardening and wear-resistant functions can be prepared. The product prepared by adopting the method can modify optical properties, mechanical properties, chemical stability properties and the like of an organic polymer material, and the prepared composite master batches can be used for conveniently producing a plastic plate or thin film and can be widely applied to the fields of buildings, automobiles, ships and the like.

Description

technical field [0001] The invention relates to a method for preparing an optical film, in particular to a method for preparing a hardened and wear-resistant optical film by one-step co-extrusion stretching, and belongs to the technical field of optical materials. Background technique [0002] The uniform compounding of functional inorganic nanomaterials and organic polymer materials has always been a research hotspot in the field of composite materials. Because general organic polymer materials have the advantages of simple production, easy processing and molding, high transparency, and low cost, but also have disadvantages such as poor weather resistance and weak functionality; while inorganic materials have good temperature resistance and multi-function (anti-static, anti-ultraviolet) , anti-fouling, anti-static) and other advantages, but the disadvantage is that it is not easy to process and shape, especially the shortcomings of non-geometric rules that are difficult to ...
