This invention provides a dyne pen ink, its preparation method, and its application. The dyne pen ink comprises ether compounds selected from ethyl carbitol and / or butyl carbitol. Through the design of the dyne pen ink components, this invention provides a novel, more environmentally friendly dyne pen ink with a 2-second observation time, without using toxic, carcinogenic, teratogenic, and reproductively toxic ethylene glycol ethyl ether. Furthermore, the dyne pen ink provided by this invention significantly improves abnormal shrinkage in smaller sizes (22-33), resulting in more accurate dyne values ​​obtained from testing, and the testing process does not significantly impact the health of the testers.

The present application relates to a kind of high breakdown voltage ceramic capacitor and its preparation method, capacitor includes: barium titanate base round ceramic sheet layer, glass glaze layer and electrode layer;Wherein, glass glaze layer covers in the side of barium titanate base round ceramic sheet layer, and the whole area at the distance of 0.2-0.5mm from upper and lower round face edge;Glass glaze layer upper portion is covered with electrode layer;The raw material of glass glaze layer includes: glass powder and organic carrier;Wherein, the raw material of glass powder includes: MgO, TiO2 、 Al2O3 And SiO2 ;The raw material of organic carrier includes pinene alcohol, butyl carbitol and acrylic resin.The present application increases glass glaze layer on ceramic sheet layer, since the dielectric constant of glass is much smaller than ceramic, so most voltage load is borne by glass glaze layer, and the anti-breakdown performance of glass material is far superior to barium titanate base round ceramic sheet, can satisfy in the premise of guaranteeing not to influence electrical property still can improve anti-breakdown.

This invention belongs to the field of printed circuit technology and provides a copper electronic paste for glass-based printed circuits and its preparation method. The copper electronic paste for glass-based printed circuits includes composite modified copper powder, modified glass powder, and an organic carrier. The composite modified copper powder is composed of modified spherical copper powder and modified flake copper powder. The modified spherical copper powder is obtained by modifying spherical copper powder with an organic titanate, and the modified flake copper powder is obtained by modifying flake copper powder with a silicate. The modified glass powder is obtained by modifying glass powder with polyethyleneimine and a phosphate coupling agent. The glass powder is obtained by mixing B2O3, Bi2O3, ZnO, SiO2, Al2O3, P2O5, TiO2, ZrO2, La2O3, and MoO3 and then melting, water quenching, drying, and grinding. The organic carrier includes terpineol, butyl carbitol acetate, ethyl cellulose, and a thixotropic agent.

This invention relates to the field of conductive paste preparation technology, providing an organic carbon nanotube conductive paste and its preparation method. The paste uses a binary organic solvent system composed of butylcarbitol and DMF, achieving efficient deagglomeration and uniform dispersion of carbon nanotubes without the need for dispersants. The preparation method includes: premixing DMF and butylcarbitol, adding carbon nanotube powder for further premixing, and finally obtaining the conductive paste through sand milling. This method ensures uniform dispersion and high stability of the paste by precisely controlling the solvent ratio, premixing parameters, and sand milling conditions. This invention overcomes the technical bottleneck of traditional dispersants limiting conductivity, simplifies the process, reduces production costs, and simultaneously improves battery energy density and fast-charging efficiency.
