Description
Technical field
The invention belongs to advanced composite material technical field, be specifically related to a kind of folding matrix material.
Background technology
Material is the pillar of modern science and technology and social development, and the competition of modern high technology depends on the development of Materials science to a great extent.So-called polymer is often referred to the macromolecular cpd connect with chemical bond by ten million micromolecular compound.Commodity polymer material is divided into the 5 large classes such as plastics, rubber, fiber, tackiness agent, coating.Matrix material is the heterogeneous material prepared through recombining process by two or more the material such as metallic substance, stupalith or macromolecular material, various material makes up for each other's deficiencies and learn from each other in performance, produce synergistic effect, make the over-all properties of matrix material be better than former composition material and meet various different requirement.The development of modern high technology be unable to do without matrix material, and matrix material, to the development of modern science and technology, has very important effect.The depth of investigation and speed and the scale of applying range and production development thereof of matrix material, become one of important symbol of a measurement national science advanced technology level.Matrix material mainly can be divided into structural composite material and the large class of functional composite material two.Functional composite material is generally made up of functive constituent element and matrix constituent element, and matrix not only plays integrant effect, and can produce collaborative or add powerful effect.Functional composite material refers to the matrix material providing other physicalies except mechanical property.As: conduction, superconduction, partly lead, magnetic, piezoelectricity, damping, suction ripple, wave transparent, friction, shielding, fire-retardant, folding, sound absorption, heat insulation etc. highlight a certain function, be referred to as functional composite material.Functional composite material is primarily of functive and reinforcement and matrix composition, and functive can be made up of one or more functional materialss.The matrix material of pluralistic function body can have several functions, meanwhile, also likely produces new function due to complex effect.Multifunctional composite is the developing direction of functional composite material.
The exploitation of novel material is the guide that Materials science develops with research, is the foundation stone of 21st century six large high-tech area.Matrix material is type material, because of diversified function and outstanding performances such as its folding, antifatigue, high temperature resistant, vibration dampings, be used widely in fields such as the Aeronautics and Astronautics over nearly 30 years, the energy, traffic, machinery, building, chemical industry, biomedicine and physical culture, 21 century Material Field opened one's arms and met the arrival in matrix material epoch.Along with matrix material development and application, matrix material has been formed in the middle of network penetration to industry-by-industry field.
Folding resistance (folding endurance) refers under certain stress, and paper, cardboard, plastics sheet or film bear weather resistance when reacting bending or folding at a certain temperature.It is the ability that experimental material resists local structural variation and subsurface defect development under repeated stress and effects of strain, has very large practicality.At present, strongthener mainly S high-strength glass fibre, carbon fiber and the aramid fiber of advanced composite material, aramid fiber is the common name of aromatic polyamide fibrid.It is that a kind of intensity is high, the high and low density of modulus, folding, synthetic that wear resistance is good organic fibre, but thermal characteristics is always barely satisfactory.
Summary of the invention
The object of this invention is to provide a kind of folding matrix material, it has excellent folding quality.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of folding matrix material, makes by after the hot pressing of folding preformed objects; Described folding preformed objects is (53 ~ 62) by mass ratio: (1 ~ 3): (18 ~ 20): (14 ~ 18): (11 ~ 13): (15 ~ 16): (6 ~ 8): (5 ~ 8): (18 ~ 25): (2 ~ 5): (12 ~ 15): the polyimide resin of (7 ~ 12), azanol potassium, 1,3-two (isocyanatomethyl)-hexanaphthene, polyether glycol, phenoxy resin, rosin polyoxyethylene ester, thioacetamide, phenylcyclohexane, bisphenol A dianhydride, tetrazolium, stearic acid, Cobalt Phthalocyanine are that raw material obtains;
The molecular weight of described polyimide resin is 3000 ~ 5000;
Described phenoxy resin molecular weight is 10800 ~ 14500;
The molecular weight of described rosin polyoxyethylene ester is 800 ~ 1500;
The molecular weight of described polyether glycol is 3800 ~ 5500.
In the present invention, described polyimide resin by 3,3 ', 4,4 '-benzophenone tetracarboxylic dianhydride and 12 methylenediamine condensation reactions obtain.
In the present invention, by polyether glycol, phenoxy resin and bisphenol A dianhydride being combinationally used, excellent heat resistance can be obtained and the more tough and polymkeric substance of excellent solvent resistance.By adding rosin polyoxyethylene ester, thioacetamide, phenylcyclohexane, the even density of the filler in system, can obtain good mix, becomes the paste-like being easily prepared into and having mobility; Be conducive to polymer polymerization.
In the present invention, azanol potassium can form small molecules hapto when resin solidification, is conducive to resin system evenly crosslinked, generally exists with the methanol solution of azanol potassium; Rosin polyoxyethylene ester, also known as polyoxylethylene abietate, take rosin as raw material, obtains under base catalysis with ethylene oxide polymerization.
In the present invention, organic object is the primary bond composition of solid gums, and the bonding force that molecular weight (state of cure) shows for organic constituent has material impact, reactive when in particular concerning the consistency of each component and solidify; Low material rate of drying is comparatively slow, and high resin system is not good to the wettability of inorganic filler.Organic-compound system of the present invention is not only uniformly dispersed being uniformly mixed in process, and overflow is moderate in bonding processes, evenly crosslinked.
In the present invention, preferably, polyimide resin, azanol potassium, 1,3-two (isocyanatomethyl)-hexanaphthene, polyether glycol, phenoxy resin, rosin polyoxyethylene ester, thioacetamide, phenylcyclohexane, bisphenol A dianhydride, tetrazolium, stearic acid, Cobalt Phthalocyanine that described folding preformed objects is 60: 2: 18: 15: 11: 16: 7: 7: 20: 5: 15: 10 by mass ratio are that raw material obtains.
In the present invention, Cobalt Phthalocyanine, stearic acid, polyether glycol are mixed, within 2 hours, obtain mixture in 85 DEG C of reactions; Successively two for 1,3-(isocyanatomethyl)-hexanaphthene, thioacetamide, bisphenol A dianhydride, rosin polyoxyethylene ester are added in mixture, stir 4 hours in 110 DEG C, then add phenylcyclohexane, azanol potassium, stir 1 hour in 120 DEG C; Finally add polyimide resin, phenoxy resin, tetrazolium, stir 0.5 hour in 120 DEG C, obtain folding preformed objects; Insert in mould by folding preformed objects again, namely hot pressing obtain folding matrix material.Heat pressing process is: 0.3MPa/130 DEG C/0.5 hour+0.3MPa/150 DEG C/1 hour+0.5MPa/170 DEG C/2 hours.
Because technique scheme is used, the present invention compared with prior art has following advantages:
