The astral message of negotiable securities, check according to look forward to check data to show times new material (600458) new obtain to invent patent accredit, patent name is " colophony of heavy analyse fiber reachs the Wei Fangguan between a kind of tall electrical conductivity its are heavy " of method of analyse fibrous preparation, patent application date is CN202211267479.6, accredit day is on January 19, 2024. Patent summary: This invention belongs to domain of technology of fiber of fragrant black silk ribbon, made public the Wei Fangguan between a kind of tall electrical conductivity method of preparation of resinous of heavy analyse fiber, will benzene 2 amine are deliquescent in DMAc, ordinal join a benzene 2 armour acyl black lead of electric conduction of chloric, modified / fluid of DMAc in suspension, 2 armour of benzene acyl is chloric have reaction, rejoin LiOH is pulverous / fluid of DMAc in suspension, adjust PH comes neuter or weak acidity, get namely. This method can happen from what go up to prevent effectively to guide calcium carbide Chinese ink reunites at all, be in dispersedly as dispersive even stability a Wei Fangguan colophony is medium. Still made public the Wei Fangguan between a kind of tall electrical conductivity method of preparation of heavy analyse fibrous, colophony of heavy analyse fiber passes sparge caky shaping means, fiber exterior shows a velar shape and fiber broom to change condition, the felt performance of paper is strong, preparation craft is simple, low to the requirement of equipment, industry turns production continuously feasibility is tall. Times new material is new since this year obtain patent authorization 6, relatively the corresponding period decreased last year 50% . Combinative company signs up for financial data in 2023, 2023 the company threw 380 million yuan in respect of research and development first half of the year, add compared to the same period 31.89% .
