High-definition high-heat-insulation low-internal-reflection nano ceramic solar film

Abstract

The invention relates to the technical field of thin films, in particular to a high-definition high-heat-insulation low-internal-reflection nano ceramic solar film. The nano ceramic solar film comprises a release film, a first heat insulation adhesive layer, a first PET base film, a second heat insulation adhesive layer and a second PET base film which are sequentially connected. The first heat insulation adhesive layer and the second heat insulation adhesive layer are composed of pressure-sensitive adhesive and nano slurry, the nano slurry comprises nano tungsten oxide, the D50 of the nano slurry is smaller than 75 nm, and the D97 of the nano slurry is smaller than 100 nm. The obtained solar film is high in definition and good in heat insulation performance, the near infrared rejection rate is larger than 93%, the haze is 1.1% or below, and the solar film has low internal reflection performance.

Description

Technical field [0001] The present invention relates to the field of thin film technology, in particular, to a high-definition high heat-insulating low-inspectirers, reflective nanopharacene solar membrane. Background technique [0002] The development of the solar membrane has now had nearly 50 years, and the existing vacuum magnetron sputtering technology has produced the solar film in the late 1990s. It has experienced a variety of technological innovations, and the magnetron sputtering process is nickel, silver, titanium. Advanced aerospace alloy materials such as gold and ceramic materials use the most advanced multi-cavity high-speed rotating equipment, using electric fields and magnetic field principles high-speed high-speed high-speed high-speed, on high tension PET substrate, but metal is easily oxidized, The shelf life is shorter and can shield the signal. In the current life, the metal ions are easily generated to produce secondary radiation. So in the past ten years, ...

Problems solved by technology

[0002] The development of solar film has a history of nearly 50 years. The existing vacuum magnetron sputtering technology to produce solar film was produced in the late 1990s and has undergone various technological innovations. The magnetron sputtering process is nickel, silver, titanium Advanced aerospace alloy materials such as gold, ceramic materials, etc. adopt the most advanced multi-cavity high-speed rotating equipment, and use the principle of electric field and magnetic field to uniformly sputter metal particles on the high-tension PET substrate at high speed and high force, but the metal is easy to oxidize. The shelf life is short and can shield the signal, causing inconvenience in today's life, and metal ions are also easy to produce secondary radiation to the human body

Therefore, in the past ten years, the entire solar film industry has been developing towards the cost-effective nano-tungsten oxide-doped ceramic film with high heat insulation. Solar-like films have deep optical defects

The existing ceramic solar film has problems such as low clarity, large haze, low heat insulation performance, no attenuation, and insufficient light transmittance.
