Peaceful wave material is in low viscosity to shrink aldehyde but respect of degradation epoxy resin gains headway

In recent years, biology of place of peaceful wave stuff base Ma Songqi's researcher waits for group of high polymer data be based on can solve the chemical bond that leave to develop easy recuperative heat product of series of solid sex colophony. Arrive to get high-powered, be able to bear or endure ability in swimming, shrink aldehyde but colophony of sex of degradation hot solid, design of Ma Songqi group synthesized annulus of snail of the couplet that contain benzene 2 shrink couplet of aldehyde, benzene and annulus 2 shrink aldehyde and benzene couplet only link shrink the colophony of aldehyde structure. The function such as temperature of its vitrification transition, mechanical intensity and epoxy resin of traditional double phenolic A comparative taller even. Close, they second from processing angle the design synthesized low viscosity but monomer of degradation annulus oxygen, through vacuum auxiliary colophony delivers moulding to shape craft (abbreviation “VARTM” ) , preparation gives performance exceedingly good easy reclaim carbon fiber composite material. In cricoid shrink second radical introduces on aldehyde structure or methylic hind, of annulus oxygen monomer neat the gender is broken, the interaction between the element is abate, got the annulus oxygen monomer of 3 kinds of low viscosity, viscosity is low achieve 0.7Pa·s, far under monomer of oxygen of annulus of double phenolic A (DER331 of contented family name) viscosity (10Pa·s) . Monomer of oxygen of 3 kinds of annulus has the characteristic with solidify tall active, ketone of Er of classics different Buddha has good heat, mechanical property after 2 amine solidify. As a result of the characteristic of low viscosity, the product can shape through VARTM craft preparation becomes carbon fiber composite material. Gotten composite material shows superior tensile strength (635.9±24.1MPa) , Yang model is measured (25.5±0.7GPa) and rupture percentage elongation (5.9±0.9% ) . Because shrink aldehyde the degradation performance with epoxy resin superior matrix, composite material immerses in 0.1mol/L HCl acetone / H2O (9:1, v/v) 24h of the room temperature in solution, can reclaim carbon fiber, reclaiming carbon fiber surface remains without colophony. And because reclaim the condition is gentle, avoided the loss of appearance, chemical to form of carbon fiber surface composition and mechanical function, the carbon fiber that makes reclaim can repeat for many times use. The carbon fiber composite material that second birth gets, held the exceedingly good heat of composite material of primitive carbon fiber, mechanical property. This job will guide but researcher of colophony of sex of degradation hot solid the design that from treatment and function two respects begin molecular construction works, be helpful for driving this kinds of resinous application.
