Preparation and Characterization of High Properties Cyanate Ester Resin Based Carrier Adhesive Films
摘要
Abstract
Cyanate esters suffer from poor processability and brittleness,which are detrimental to the preparation of carrier adhesive films and affect the final bonding performance.To address these issues,bisphenol A cyanate ester resin was toughened and modified with phenoxy resin and montmorillonite,and then combined with basalt fiber to fabricate the modified cyanate ester resin carrier adhesive film.The processability and curing behavior of the modified resin were tested and analyzed.The cyanate ester modified with phenoxy resin exhibited good film-forming properties and a low curing temperature,making it suitable for the preparation of carrier adhesive films.The bonding strength of the pure cyanate ester resin carrier adhesive film was 11.1 MPa.The bonding strengths of the cyanate ester carrier adhesive films toughened solely with montmorillonite and phenoxy resin were 12.7 MPa and 13.0 MPa,respectively,representing an increase of 14.4%and 17.1%.The resin carrier adhesive film toughened with a combination of 10%mass fraction of phenoxy resin and 2%mass fraction of montmorillonite achieved the best bonding effect,with a bonding strength of 13.7 MPa,an increase of 23.4%.Additionally,the thermal and dielectric properties characterization showed that the composite material had a 5%weight loss temperature of 396.0℃,a glass transition temperature of 240.7℃,and a dielectric constant and dielectric loss of 3.2 and 0.04,respectively.The prepared carrier adhesive film has excellent bonding strength,thermal stability,and dielectric properties,making it suitable as a high-temperature-resistant and transparent bonding material for radomes.关键词
