(1), by in hard polyurethane foam, adding nanometer SiO
2, can the good PU/SiO of obtained performance
2Matrix material.KH-570 and nanometer SiO
2Chemical reaction taking place make nanometer SiO2 surface functionalization, and carries out chemical reaction with the active segment of polyurethane-base; SEM shows, though SiO
2Particulate is wrapped in the matrix and has had than the bigger size of initial viewed particle, but it has still kept initial shape and dispersiveness substantially, nanometer SiO
2Can be dispersed in uniformly in the PU matrix.
(2), PU/ nanometer SiO
2The mechanical property of matrix material obviously is better than pure urethane.Generate nanometer SiO through original position
2The modulus of compression of enhanced polyurethane foam system is apparently higher than not strengthening system.When nanometer SiO2 addition reaches 1wt.%, and to compare with the density foam system, the compressive strength that strengthens foam system reaches maximum, can improve 60%.The compressive strength of RPUF is along with SiO
2The increase of addition raises earlier, is that 1wt.% reaches maximum up to the SiO2 amount of filling, reduces again subsequently.When addition surpassed 3wt%, the modulus of compression that generates nanometer SiO2 enhanced polyurethane foam system through original position was starkly lower than and does not strengthen system.

Embodiment 3, nano-silicon oxide modified polyurethane elastomer: polyether glycol (100), TDI (18), ethylene glycol (3.13).Nanometer SiO2 add-on and coupling agent kh-570 content have been analyzed the influence of nanometer SiO2 to the PUE thermostability to the influence of polyurethane elastomer mechanical property, and the coupling agent and the nanometer SiO2 mechanism of action have been carried out deep discussion.Nanometer SiO2 strengthens PUE and has experienced the process that reduces after the first increase, and its optimum addition is respectively 6%, and the optimum addition of silane coupling agent is 1%.Through KH-570 surface-treated nanometer SiO2, because itself and polyurethane matrix have formed stable chemical bond, reinforced effects is obviously good than untreated.Inquired into the failure mechanisms of filler enhancing polyurethane elastomer.The adding of nanometer SiO2 can change the crystal habit of urethane soft or hard section, makes crystallite refinement more, and a section crystallite is blended in soft section firmly, has improved the microphase-separated of polyurethane elastomer, thereby has improved mechanical behavior.
TGA studies show that nanometer SiO2 has improved its thermostability greatly owing to improved the microphase-separated degree, and heat decomposition temperature has improved 25 ℃.
Embodiment 4, nano-silicon oxide modified polyurethane elastomeric fiber (Polyurethane Fibre) abbreviate the PU fiber as, are referred to as " Spandex " in the world (Spandex), and the Chinese commodity title is spandex.Spandex has the such elasticity of rubber thread.Some performance is better than rubber thread, and is thin as fiber number, and powerful high, Young's modulus is big, and proportion is little, and dyeability and fastness are better etc., are a kind of tencels with good textile performance, thereby extremely pay attention to.
At first to have a special chemical The Nomenclature Composition and Structure of Complexes relevant with it for the excellent properties of spandex.The polymer chain structure of polyurethane elastomeric fiber is to be formed through block copolymerization by the polyethers of flexibility or polyester segment and inflexible aromatic diisocyanate segment.The soft segment intermolecular interaction is few, can freely stretch, and this has just caused spandex fiber that bigger elongation performance is arranged, and rigid chain segment molecular chain then bonding force is bigger, molecular chain can unrestrictedly not extended, thereby make spandex fiber have high resilience.According to the polyester type and the polyether-type of soft chain segment in the molecular chain, polyurethane elastomeric fiber can be divided into polyester and polyethers two big classes.
(1) PAUR spandex fiber
Making molecular weight by hexanodioic acid, ethylene glycol, propylene glycol through condensation reaction is that 1900 polyester adds nano silicon oxide, generates performed polymer with excessive MDI reaction, adds appropriate solvent (for example methylethylketone etc.), carries out wet-spinning.Through the quadrol precipitation bath, the skin of fiber forms the urea key and becomes solid, the internal layer of fiber then in spinning after water impregnating by pressure and be completed into crosslinked.
(2) polyether(poly)urethane spandex fiber
The hydrolysis of polyether-type polyurethane spandex fiber, performance such as antimicrobial are all superior than polyester type elastomer fiber.Therefore, on fabric, use comparatively ideal, since Lycra comes out, done many improvements at the aspects such as stability, dyeability and spinning technique of fiber.The spinning processes of spandex is similar with the production of general synthon, can adopt dry-spinning, wet-spinning, melt-spinning and four kinds of spinning technique technologies of chemical reaction spinning.
(1) dry-spinning
Dry-spinning is the widest a kind of method of producing spandex that adopts in the world at present, and large manufacturers such as U.S., moral, day all adopt dry-spinning to produce, and the output of dry-spinning accounts for ultimate production more than 80%.
Dry-spinning is to be raw material with the urethane behind the chain extension, make solvent with dimethyl formamide (DMF) or dimethyl hexanamide (DMAc), it is 25%-35% that heated and stirred is made concentration, viscosity is the solution of 10-80Pa.s, after adding additive, after filtration, deaeration, degasification obtain the uniform spinning solution of viscosity.Again with spinning solution with accurate toothed gear pump quantitative and even be pressed into spinning top, from the aperture of spinning jet, be extruded and form thread to enter diameter be 30-50cm, long 3-6m, temperature is 260-250 ℃ a spinning stack, high-temperature gas in the path is evaporated solvent from the stoste thread very soon, strand concentration improves constantly until being frozen into the 0.6-1.7tex monofilament, then boundling and aftertreatment such as oil. be wound into an ingot at last.According to the difference of linear density, each spinning stack can pass through 1-8 spandex fiber tow simultaneously.When producing in this way, be also noted that the recovery of solvent is purified.
The dry-spinning winding speed reaches as high as 1000m/min generally at 200-600m/min; The fiber number of gained fiber is 22.2-29.4dtex; Its production unit takes up an area of and amasss little simultaneously.This spinning processes technology maturation is made quality of fiber and excellent property.
(2). wet-spinning
Wet-spinning is a physical process fully, by the diffusion of molecule. make solvent diffusion in the liquid thread that from spinning nozzle, comes out in precipitation bath, and then be cured as tow.The dimethyl acid amide of polyurethane polymer or dimethyl acetic acid amine or tetrahydrofuran solution are squeezed in the precipitation bath, and precipitation bath is generally water or alcohol, solidify soon for the precipitation bath fiber surface with water, but there is the fold phenomenon on the surface, the even structure of fiber when doing precipitation bath with alcohol, and brute force is also high.Precipitation bath concentration is 15%-30%, and keeps the precipitation bath circulation.Because the diffusion of molecule is slow, the wet method setting time is long, so bath generally needs about 20m, its former sections baths work to solidify tow, and the back has been a washing effect for several sections.Strand after going out to bathe oils before dryness finalization, in case tow is also sticking.The tow of dryness finalization is rolled onto on the simple pipe after once oiling again.Similar with dry-spinning, the linear density of monofilament is 0.6-1.7tex, and a wet production line can be produced 140-300 bar tow simultaneously.The wet spinning technology complexity, factory building and facility investment expense are big, because of the precipitation bath fluid resistance defines thread that spinning solution extrudes and the rate of dispersion of solvent makes spinning speed lower, be generally 50-150m/min, so production cost are higher.And the dryness finalization temperature is 250-270 ℃, and dried strand need be through the stretching about three times.The fiber number of the made fiber of this method is, 5-400tex,
The spandex output of wet-spinning accounts for 10% of total amount, this spinning processes complex process at present. and spinning speed is low, and the production cost height is not so tempo is very fast.
(3). melt-spinning
Melt-spinning is that dried section is entered screw extruder, section is owing to be heated and fusion, melt is extruded and is delivered to spinning part with certain pressure, with spinning pump melt quantitative is depressed into spinning jet equably then, the melt thread is extruded from the spinning jet aperture, cools off and solidificating fiber in the path.Melt-spinning only is applicable to the polymkeric substance that has good stability under eutectic and the melt temperature, as reacting prepared block polymers of polyurethane by aromatic diisocyanate and linear polyether glycol.The polyether polyols with reduced unsaturation general with 1, that the 4-chain expansion of succinic acid generates, this system normal temperature are down solid, and fusion in the time of 160-220 ℃ is extruded after the fusion to enter from spinning appts and stretched in the hot water bath, and its spinning speed is 200-800m/min.
The melt-spinning technology flow process is simple, cost of raw and processed materials or cost of equipment be very economical all, and its production efficiency height particularly can flammable and toxic solvents, therefore need not resemble dried, the wet spinning need be with expensive recovery system, and its product thermotolerance, oxygen resistence, biocompatibility are all better.But because urethane is unstable under processing temperature, in the pyritous residence time when long slightly, can take place excessive crosslinkedly, generate gel, its physical and mechanical properties is relatively poor.
The production company of melt spun spandex mainly is a Japanese firm, for example day spins clearly, clock spins, Kuraray, printing ink chemical industry and big plug fine jade company etc.Its production method mainly contains single stage method, two step method and blocking method.The melt-spun method is new in recent years spandex fiber technology of rising, and comes into one's own day by day, and technology reaches its maturity, and is a dark horse with its distinctive advantage, becomes the spandex fiber technology of tool future rapidly.
(4). the chemical reaction spinning
It is the polyester of vulcabond or polyethers performed polymer to be contained in two ends extrude and advance people's spinning bath through the volume pump spinning nozzle, with chain spreading agent (as diamines) the component generation chemical reaction in the spinning bath, when increasing, prepolymer chain generates the covalency interlinkage structure nascent fibre that is insoluble to dimethyl formamide.The strand that comes out from reactive bath technique is dry qualitative through sending into behind the quadrol that spray header flush away strand is carried secretly on the dry qualitative machine.Nascent fibre hardens in the water of pressurization so that still unreacted portion is crosslinked in its inside, thereby is transformed into the block polymers of polyurethane of three-dimensional structure after reeling.The spinning speed of reaction spinning is generally 50-150m/min, and the fiber number of monofilament is 1.1-3.7tex, and the fiber number of last fibre bundle is generally 4.4-340tex, decides according to need.The shortcoming of chemical spinning is that its efficient is lower, and has the diamines environmental pollution problems, at present in the world in this way the output of spinning less than 10% of ultimate production.The Globe of the U.S., Hispanic Enkaswing, companies such as the Spanzelle of Britain all in this way.
(5). the nascent fibre that the fiber aftertreatment obtains after spinning, the surface has viscosity, the nascent fibre that obtains by dry-spinning and melt-spinning particularly, and surface viscosity is bigger, can adopt diverse ways and treatment agent, fiber surface be handled as talcum powder, water, finish etc.The mixture that the treatment agent that industrial production is used is made up of multiple material, they have also improved the oilness and the static resistance of fiber when reducing fiber surface viscosity.
Adopt coupling agent that nanometer SiO2 is carried out surface treatment earlier, then it is added the RH-10 high-speed mixer with polypropylene granules and various auxiliary agent and mix high-speed mixing 3min.Be the twin screw extruder extruding pelletization of 30mm with Feitian, Beijing machine factory diameter again, prepare the particle of nanometer SiO2 modified polypropene.
Embodiment 5, nano-silicon oxide modified thermoplastic resin: content is polypropylene composite material the best of the nano silicon of 2%-4%.Studied the influence of the adding of nanometer SiO2 to the PP flowing property, by the fusion rheometer measurement, found that, when adding a kind of inorganic nanoparticles period of the day from 11 p.m. to 1 a.m, the matrix material melt flow rate changes greatly, this mainly is that because specific surface area is big, the interface bonding is occupied an leading position because when adding separately a kind of nanoparticle.Nanometer SiO2 has the effect of heterogeneous nucleation agent for PP.Fill a small amount of nanometer SiO2, promptly cause PP spherocrystal particle tiny, even, with nanometer SiO2, content improves, and then the nucleus of Xing Chenging is just many more, and spherulite size is more little.We see and have limited with the interpolation of learning the SiO2 particle that the imperfection crystalline forms among the PP by the polyacrylic crystallisation process of polarized light microscope observing and black cross delustring image.Studied the influence of the adding of nanometer SiO2 to the matrix material crystalline state, X-ray diffraction analysis shows, the people that adds of SiO2 has restraining effect to the crystallization of β crystalline substance among the PP, has correspondingly improved the relative content of each a crystalline substance.
Embodiment 6, nanometer SiO2 add HDPE, and the melt flow index of discovery HDPE descends but amplitude is little, and tends towards stability after SiO2 content reaches 6%; Tensile strength is fallen after rising, and Young's modulus improves a lot, and elongation at break descends a lot.When determining that nanometer SiO2 content is 5.5wt.%, comprehensive mechanical property the best; SiO2 content is the grain-size that the size of the crystal grain of HDPE under polarizing microscope of 4wt.% is significantly less than pure HDPE, and the effect of heterogeneous nucleation has been played in the adding of this proof nanometer SiO2.And little grain-size helps improving the shock strength of material, thereby has further proved the adding of nanometer SiO2, and the HDPE matrix has been played the toughening modifying effect; The DSC data show that nanometer SiO2 carries out the crystal fusion of HDPE at a lower temperature, and this makes the crystallization grain refining of HDPE relevant with nanometer SiO2; Different degree of crystallinity has bigger influence to the ESCR performance of HDPE, and careful crystallization can improve the ESCR performance of HDPE.Can predict that thus nanometer SiO2 has remarkable effect to the ESCR performance that improves HDPE; HDPE is the material very responsive to ESCR, and its influence factor is a lot.Wherein, microcavities and crystal defect can absorbing mediums, bring out crazing and cause final cracking, and sheet intergranular link molecule then can stop cracking effectively; The effect of heterogeneous nucleation has been played in the adding of nanometer SiO2 in the compound system crystallisation process, refinement the HDPE crystal, the molecular chain that helps compound system is around the generation of nanometer SiO2 ordered arrangement agglomeration process, crystallization rate is accelerated; The SiO2 nano particle forms the physical crosslinking point between the polymer macromolecule chain on the other hand, has limited the motion of molecule segment, can effectively stop crazing to develop into fracture.Therefore, prediction nanometer SiO2 has had sufficient theory and test basis to the ESCR performance that improves HDPE.
Embodiment 7, nano-silicon oxide modified thermosetting resin: in resol, add thermoplastic resin, the two-phase of elastomerics grade in an imperial examination, improve shock strength, be called " outer toughness reinforcing " method.Two-phase can be blended in thermoplastic resin toughness reinforcing by melt blending (mixing method) or solution blending is to be thermoplastic resin and the resol blend of 7-15 with solubility parameters, also is a kind of simple toughness reinforcing approach.The thermoplastic resin that adopts mainly contains polyvinyl alcohol, polyvinyl acetal, polyphenylene oxide etc.As adopt polyvinyl acetal that resol is carried out modification, and not only can improve fragility, improve adhesive power and physical strength, and reduced the curing molding pressure of resol.Resol contains the phenolic hydroxyl group of easy suction, and by the modification of polyvinyl acetal, cut apart and surrounded phenolic hydroxyl group, thereby toughness is increased, but owing in the resol three dimensional structure, introduced long aliphatic chain, so thermotolerance reduces.Adopt the higher polyvinyl formal acetal of thermotolerance to replace polyvinyl butyral acetal, can reduce heat-resisting loss.
Embodiment 8, nano-silicon oxide modified polyurethane coating: press embodiment 1,2,3,4 prescription, can prepare as required and have abscess or elastic polyurethane coating, coating, at synthon, natural fiber such as terylene, acrylic fibers, polypropylene fibre; Negative ion is released in 1000-10000/cm3 on the fabrics such as cotton, fiber crops, silk, hair, and uvioresistant, thermotolerance are improved.
Embodiment 9, nano-silicon oxide modified polyurethane adhesives: press embodiment 1,2,3,4 prescriptions, can prepare all kinds of polyurethane adhesive materials as required, at synthon, natural fiber such as terylene, acrylic fibers, polypropylene fibre; Negative ion is released in 1000-10000/cm3 on the fabrics such as cotton, fiber crops, silk, hair, and uvioresistant, thermotolerance are improved.Can prepare multiple tamanori by modifications such as acrylic acid or the like tamanoris.
