AI Technical Summary

Problems solved by technology

For example, although the liquid crystal UV curing furnace has an air-cooling system, sometimes the temperature of the UV curing furnace can be as high as 80°C, which can easily lead to the adhesion of the protective patch of the liquid crystal due to high temperature heating.

Embodiment 1

[0013] Nano multilayer film: 25nmTiO 2 / 14nmAg / 25nmTiO 2 / G

[0014] Film layer design: using the theory of induced transmission, taking λ=365nm as the characteristic wavelength, and measuring Ag and TiO 2 The optical constant of the film is calculated, the thickness of each film layer is initially selected, and the coating test is carried out. Then according to the test feedback, the optimal thickness of the film layer is specifically determined through computer optimization.

[0015] The preparation process is as follows: the substrate is a polished quartz crystal slice 35mm×20mm×1mm and a Si(111) sheet. Chemical and ultrasonic cleaning. The substrate temperature was 45°C. Vacuum degree: background vacuum 1×10 -2 Pa, after bombarding the substrate with an ion beam for 15 minutes, then pump the vacuum to 1×10 -3 Pa. Raw material and heating source: Ag: particles with a purity of 99.9%, heated by molybdenum boat resistance wire; TiO 2 : The purity is 99.9% particles, ...

Abstract

A thermally insulatnig multi-layer transparent nano-membrane for the ultraviolet solidifying oven is composed of two surficial TiO2 layers and a silver layer between two TiO2 layer. It can be coated on the quartz glass and then used for ultraviolet solidifying over for isolating the heat in order to ensure the solidifying quality.

Description

technical field [0001] The invention relates to a nano multilayer functional film used in the technical field of nano optical thin film materials, in particular to a transparent multilayer film used for ultraviolet curing and heat insulation. Background technique [0002] As an important process, UV curing is widely used in the printing industry and liquid crystal display manufacturing industry. UV curing is a glazing process that utilizes UV (Ultra Violet) irradiation energy to cure free radical polymerized acrylate coatings to form a film. UV curing has the characteristics of fast curing and low temperature curing, which helps to improve product quality, maintain color consistency, shorten printing time, prevent air pollution, reduce fire hazards and improve the working environment. It solves the adhesion of solvent-based glazing coatings caused by temperature and humidity changes. Mercury lamps and metal halide lamps are commonly used in ultraviolet curing lamps. The ul...
