Compound process of refrigerating metal plate

Abstract

The invention discloses a compound process of a refrigerating metal plate. The compound process includes the machining steps that (1), materials are prepared, specifically, a protective film, aluminum, a radiation refrigerating film, a substrate and compound glue prepared from a main agent, a curing agent and a diluent in a certain proportion are prepared; (2), melting and evaporation of metallicaluminum are carried out through a vacuum aluminizing method, so that aluminum vapor is precipitated and accumulated on the surface of one side of the radiation refrigerating film; (3), a gluing machine is started to glue on the upper surface of the substrate, and then the glued substrate is put into a dryer for drying; (4), a compound machine is started, the glued substrate in step 3 is put intothe compound machine, so that the glued side of the substrate is compounded with the aluminum-plated radiation refrigerating film obtained in step 2; (5), a cross-cut cupping test is carried out; and(6), aging is carried out for 24 hours. According to the compound process, by galvanizing the radiation refrigerating film and compounding the radiation refrigerating film with the substrate through the compound process, the solar energy reflectivity of the radiation refrigerating film is improved by the aluminum film, and meanwhile, the radiation refrigerating film is applied to various fields.

Description

technical field [0001] The invention relates to the field of new refrigeration materials and specifically designs a composite process for refrigeration metal plates. Background technique [0002] Radiation refrigeration technology is a new type of refrigeration technology that uses infrared radiation to transfer heat from a heat source to a cold source in outer space through the atmospheric window of infrared radiation. Traditional refrigeration technology usually needs to consume energy and resources to take away heat, while radiation refrigeration technology is Using the passive enhancement of the earth's natural cooling method, the development of high-efficiency radiative cooling technology is green, environmentally friendly, energy-saving and low-carbon, and plays an important role in slowing down the trend of global warming.
