AI Technical Summary

Problems solved by technology

Commonly used reflective condenser materials include metal plates, foils and metal coatings. The processing of these reflective materials requires technical means such as high polishing, vacuum high-temperature evaporation, etc. The problem in the corresponding processing process is that the process is too complicated, and some of them need to consume precious metals. Such as silver, etc.; this greatly increases the cost of solar energy utilization systems and hinders the popularization of solar energy utilization systems
[0004] In other application fields, most of the processing and production of reflective mirrors also adopt methods such as chemical silver plating and vacuum evaporation, and vacuum evaporation needs to be completed under high temperature and vacuum conditions, and the process conditions are too harsh, which is extremely unfavorable for reducing production costs; in addition , the chemical method will consume a lot of extra chemical substances, and the additional products will easily cause environmental pollution

Abstract

The invention provides a reflector production process. The production process comprises the following steps: S1, a low melting point metal ink is produced; S2, the low melting point metal ink is evenly coated on the back of a transparent substrate, the low melting point metal ink form a reflective film on the back of the transparent substrate; and S3, a protective film is coated on the reflective film and is used for encapsulation of the reflective film. In the invention, the production process is simple and can be completed quickly under normal conditions, so that the production and application efficiency is improved and the demand on the environment is reduced; and the low melting point metal ink is evenly coated on the surface of the transparent substrate so as to form the film with good reflecting characteristics, and the production process uses the characteristics for solar energy concentration, so that the solar light and heat utilization cost is greatly reduced. The invention also provides a reflector.

Description

technical field [0001] The invention relates to the field of reflective mirrors, in particular to a liquid metal reflective mirror and a manufacturing process thereof. Background technique [0002] With the continuous development of the global economy, the consumption of non-renewable energy such as oil, coal, and natural gas is increasing day by day, which makes the problem of energy shortage increasingly severe. It is imminent to find alternative renewable energy in various traditional energy consumption fields. As the most fundamental and largest energy source on the earth, solar energy undoubtedly occupies the core position in the future energy structure. [0003] In the utilization of solar light and heat, the first thing to face is to concentrate the scattered radiated solar energy to increase the energy density of light and heat. The efficiency and price of the concentrating device will directly affect the efficiency and economy of the entire solar energy utilization...
