Problems solved by technology

[0008] To sum up, among the current manufacturing technologies of transparent electric heating glass, it is difficult to achieve low square resistance (less than 1Ω / sq), high light transmittance (greater than 90%), and high adhesion (greater than 80N) heating wire at low cost. Manufacturing, it is urgent to develop new technologies to achieve low-cost, mass-produced high-performance electric heating glass with heating line light transmittance greater than 90%, square resistance less than 1Ω / sq, and adhesion greater than 80N

Abstract

The invention relates to a method for manufacturing transparent electric heating glass with high light transmittance and low square resistance, which combines electric field-driven fused deposition direct writing and UV-assisted micro-transfer to achieve high aspect ratio (0.7-2) and high resolution ( 1‑20 micron) heating wire of transparent electric heating glass for low cost and mass production. The method combines the advantages of electric field-driven fused deposition direct writing and UV-assisted micro-transfer technology, and has the outstanding features and significant advantages of simple process, low manufacturing cost, high production efficiency, good consistency, especially the ability to achieve high transparency Low cost and mass production of transparent electrically heated glass with light rate (greater than 90%) and low square resistance (less than 1Ω / sq). This provides a new solution for low-cost and large-scale manufacturing of large-area, high-performance transparent electrically heated glass.

Description

technical field [0001] The invention belongs to the technical field of transparent electric heating glass manufacturing, and specifically relates to a low-cost and mass-produced transparent electric heating glass that combines electric field-driven fused deposition direct writing and UV-assisted micro-transfer printing technology to achieve high light transmittance and low square resistance Methods. Background technique [0002] Transparent electrically heated glass has a very wide range of applications in many fields and products, and plays an extremely important role in defogging, defrosting and anti-icing in the fields of automobiles, aircraft, construction, display, and military. Especially in cold and humid countries and regions, the application requirements are more prominent and obvious. However, the manufacturing technology of electric heating glass at this stage is difficult to balance the low square resistance and high light transmission characteristics of electri...
