Problems solved by technology

Among the shielding window products, the coated glass variety can meet the temperature requirement, while other varieties account for more than 80% of the shielding window products with high shielding effectiveness, all of which use the structural form of glass or plexiglass + shielding mesh + PVB film, of which PVB The use of film is an important link that restricts the shielding window products from meeting the high temperature performance requirements, because the temperature resistance range of the film is only -55~+70°C, and the temperature requirement of -60°C~+85°C is met if the temperature exceeds this range. , the film will have abnormal phenomena such as glue opening, air bubbles, embrittlement, etc., and the product will not be usable

Embodiment approach

[0037] There is another way of vacuuming in this solution: use a custom-made high-temperature-resistant and high-pressure rubber bag, put the combined superimposed assembly into the rubber bag, vacuumize, and then put the rubber bag into the pressurized kettle Inside.

[0038] Both TPU film and SGP film have been widely used to make laminated glass for various applications. However, the latter two types of films are hardly used in the production of sandwich shielding glass, because there are great differences in process flow and parameters, and special experiments and explorations are required to master them. If the parameters are not suitable, the product will have air bubbles, weak bonding, wrinkled wire mesh and other waste and defective products. The TPU film used to make bullet-proof glass and the SGP film used to make hurricane-resistant glass have excellent performance. These films are applied to the production of sandwiched electromagnetic shielding glass, which will ...

Abstract

The invention discloses laminated electromagnetic shielding glass utilizing a TPU or SGP film and a production technology thereof, and relates to the technical field of shielding devices. The laminated electromagnetic shielding glass utilizing the TPU or SGP film comprises a shielding wire net and base materials which are clamped at two sides of the shielding wire net, wherein the base materials are connected to the shielding wire net through the film; and the film is the TPU or SGP film. The laminated electromagnetic shielding glass utilizing the TPU or SGP film has the advantages of being high in qualification rate, high in temperature resistance and high in impact resistance.

Description

technical field [0001] The invention relates to the technical field of shielding devices, in particular to a sandwich electromagnetic shielding glass using TPU or SGP film and a production process thereof. Background technique [0002] Electromagnetic shielding window products are mainly used in display windows that require anti-electromagnetic interference and anti-information leakage, and are used in computer displays, instrumentation display windows, and individual handheld display terminals in military, military, and air force weapons and equipment. High-end medical equipment and special industrial fields have also begun to use electromagnetic shielding window products to cooperate with the complete machine products to successfully pass the 3C (+EMC electromagnetic compatibility) certification. [0003] Shielded windows are increasingly used. In terms of conventional shielding window product quality requirements, military shielding window products undergo a series of qu...
