According to announcement of bureau of national intellectual property, inc. of science and technology of South Asia new material obtains the name does not have colophony of report of bittern low interpose one kind to combine content to reach its to apply “ for “ , CN114276668B of accredit announcement date, application date is in December 2021.

Patent summary shows, this invention does not have colophony of report of bittern low interpose one kind publicly to combine content and its application, belong to domain of technology of high polymer material. This combination content presses weight portion number plan includes: Get together benzene aether colophony 30? 60 weight portion, get together agent of solidify of silicon oxygen alkyl 10? ? Colophony of hydrogen of 45 weight portion, carbon 10? 30 weight portion, without bittern compound fire retardant 5? 20 weight portion and accelerant 0.001? ? 5 weight portion. This invention uses the cricoid structure that contains active radical group to get together agent of solidify of silicon oxygen alkyl and the synergism of carbolic hydrogen colophony that specific element measures, those who get without bittern content of combination of colophony of low interpose report is able to bear or endure ageing and consistence is good, have inferior dielectric constant and dielectric loss, tall vitrification at the same time transition temperature, hear resistance, anti-flammability and easy the advantage that store, through its component of preparation electron product is like half solidify piece, pressing plate of Fu copper layer or printed circuit board integral performance is good.
