Traditional liquid state shapes acyl of double Ma Lai inferior amine colophony (BMI) inferior tenacity block up its are in the application of aerospace domain. Through shaping in liquid state double horse is cultivated nuclear carapace particle introduces in fat network, use nuclear carapace particle to have unique double deck structure to add colophony of double horse of modified of pliable but strong. Use scanning electron microscope (SEM) shape to liquid state of modified of particle of carapace of different content nucleus appearance of form of section of system of Shuang Mashu fat undertakes study, SEM result makes clear, the liquid state of modified shapes condensate of double horse colophony ruptures exterior crackle is patulous and apparent suffocate suffocate, indication tenacity ruptures form appearance. Advanced colophony base composite material is had tall quantity, better than comparing a pattern intensity, high wear, function can be designed, comfortable shape at whole wait for superior performance, had become in order to of component of Leng Duan of engine of aviation eddy fan to replace important material of the metal, of the engine of aviation eddy fan that compares to tall hold in esteem decrease heavy, improve propulsive efficiency, reduce noise and discharge wait for the port with be had principal, but the high cost problem that its create is increasingly outstanding. In recent years, the liquid state that develops quickly shapes the technology has taller craft applicability and product measure precision at the same time as a result of efficient, low cost and become superior blame autoclave composite material to shape gradually craft. This technology basically includes colophony to deliver moulding (RTM) , vacuum assists colophony perfusion (VARI) etc shape craft, use flow of liquid state resinous to come true to shape beforehand to offending voice fiber or tissue the macerate of body shapes. Acyl of double Ma Lai inferior amine colophony (colophony of abbreviation double horse) , it is liquid state shapes one of colophony matrix with commonly used craft, the characteristic such as as better than having as epoxy resin photograph technical properties, anti-corrosive, low systole and low squirm denaturation while, have taller be able to bear or endure damp and hot, high temperature resistant reach flame retardation, can use for a long time below environment of 170 ℃ wet state, after the solidify after the course is handled, its do voice to use temperature to be able to achieve ℃ of 230 ℃ ~250 even, but traditional double horse colophony because the cross-linking density of oneself is too high, bring about condensate brittleness bigger, namely tenacity is poor. Accordingly, in maintain Shuang Mashu while fat is inherent and characteristic, crucial to its tenacity modified. Respect of modified of pliable but strong was added domestic and internationally to have a lot of research in double horse resinous, include to reduce colophony cross-linking density to add pliable but strong, add with tenacity monomer copolymerization pliable but strong and introduce “ ” of the 2nd photograph adds the method such as pliable but strong. Colophony of double horse of modified of catenary of binary amine enlarge is to pass growth element catenary to reduce cross-linking density, can elevate polymer chain paragraph freedom is spent, promotion pounds function; However, method of this kind of modified transforms in the tigidity that can reduce colophony material substantially and vitrification temperature, bring about the heat-resisting function of material to reduce. Colophony of double horse of modified of copolymerization of Xi propyl compound is the method adding pliable but strong with relatively wide application, the copolymer stability after modified, dissolvability good, technical properties is good, its condensate has tall cross-linking density, low hygroscopicity, good heat-resisting performance and mechanical property. Current, of system of colophony of tall tenacity double horse adding pliable but strong is commonly in acyl of double Ma Lai inferior on the foundation of amine and modified of copolymerization of Xi propyl compound, introduce “ structure of ” of the 2nd photograph adds pliable but strong further, for example balata elastomer is thermoplastic perhaps colophony. Among them, balata elastomer adds colophony of double horse of pliable but strong to use active liquid balata to serve as the constituent that add pliable but strong normally, use balata elastomer to depart ” of formation “ island structure, raise colophony matrix succumb be out of shape ability, make tenacity twice promotes thereby. But arise as a result of what depart, the low standard quantity of balata itself and temperature of low vitrification transition also can feedback in whole colophony system, make function of colophony system heat-resisting and tigidity are reduced. Thermoplastic colophony adds mechanism of resinous of double horse of modified of pliable but strong is to pass thermoplastic high polymer catenary and network of cross-linking of double horse colophony are formed macroscopical on even and microcosmic photogenic and separate structure, this structure can be caused effectively crazing and cut belt have waste time can, and formation dispersive photograph structure can of block up crackle patulous, rose to destroy thereby can, improve the tenacity of solidify system further. In addition, what can choose normally is thermoplastic colophony is high-powered project plastic, temperature of its vitrification transition, tigidity is taller, mix to function of heat-resisting of double horse resinous consequently rigid influence is minor, but the part that also is put in inadequacy, namely high-powered project is plastic have higher opposite element quality and taller viscosity, the meeting after its are deliquescent brings about on the high side of viscosity of colophony of modified double horse, influence technical properties. This research introduces “ ” of the 2nd photograph adds liquid state of pliable but strong to shape mechanism of double horse colophony, the double horse colophony in modified of Xi propyl copolymerization introduces nuclear carapace particle to add colophony of double horse of pliable but strong in three-dimensional cross-linking network, if pursue,1 is shown. Because nuclear carapace particle has unique double deck structure, make its can form the drop record with consecutive blame to disperse in colophony system, won't form successive photograph, won't bring about change of colophony system vitrification and temperature to drop apparently, do not affect the hear resistance of colophony matrix and thermal stability basically consequently, at the same time elastomer of balata of unlike of nuclear carapace particle is mixed thermoplastic colophony brings about systematic viscosity to increase quickly in system of fat of can deliquescent Yu Shu, disperse with form of “ latex ” however, do not affect liquid state basically to shape the viscosity of system of double horse colophony and liquid state shape the technical properties of system of double horse colophony. In this research, use SEM to be opposite respectively token of appearance of form of section of condensate of modified resin of nuclear carapace particle, use trends at the same time thermomechanical analyzer (DMA) , hot weightlessness analyzer (TGA) and universal test machine parts to heat up function of function, hot weightlessness and static state to its mechanical function undertakes study, discussed nuclear carapace particle to add liquid state of pliable but strong to shape further mechanism of double horse resinous.
