Fiber reinforcement fabric of the present invention is selected from a kind of in glass fibre, carbon fiber and the trevira, is that modulus is greater than 76000N/mm in the preferably above-mentioned fiber reinforcement fabric
2Fiber.
" monofunctional diluent " of the present invention is meant to have only an epoxy group(ing) in the molecule, and " bifunctional thinner " is meant two epoxy group(ing) in the molecule.
The present invention finds in research process, the wetting property between Resins, epoxy and the fiber reinforcement fabric and following some is closely related:
1, the viscosity of composition epoxy resin: the viscosity of composition epoxy resin is excessive, and is slow in the expansion of the surface of fiber reinforcement fabric as the composition epoxy resin of liquid phase; The viscosity of composition epoxy resin is low excessively, then in the liquid molding moulding process, can be very high to seal request, otherwise may cause resin to overflow the phenomenon of trickling.Therefore, need carry out modification, make it mix viscosity controller within the scope of 200-300Pa.s existing composition epoxy resin.
2, the gelation time of composition epoxy resin: gelation time is short, can cause composition epoxy resin also fully not infiltrate in the fiber reinforcement fabric, has just solidified, and finally can't form matrix material; Gelation time is long, can extend manufacture cycle, and causes the raising of production cost.Therefore, need the gelation time of composition epoxy resin is controlled at 5～6 hours/500g resin combination.
3, the surfactivity of fiber reinforcement fabric: fiber surface contains hydroxyl, and the reaction that can be hydrolyzed of silane coupling agent and fiber surface hydroxyl forms the Si-O-C key at the fiber reinforcement fabric face.Therefore,, change the surfactivity of fiber reinforcement fabric by adding silane coupling agent, can the strengthening ring epoxy resins and the fiber reinforcement fabric between wetting property.The coupling agent that contains siloxanes in addition has lower surface energy, thereby improves the wetting property of resin and fiber.
In the process of Resins, epoxy being carried out the modification experiment, if find only to use the bifunctional Synthesis of Oligo Ethylene Glycol as thinner, when the viscosity of Resins, epoxy reduced, its gelation time was too short, has only 3 hours/500g resin combination; Can't realize scale operation.
And if only use the simple function group Synthesis of Oligo Ethylene Glycol as thinner, owing to have only single epoxy group(ing) as reactive group in its molecule, cause cured article linear crosslinked crosslinked more than build, cross-linking density descends, the rigidity loss is serious, thereby makes the intensity of Resins, epoxy not reach requirement.
Therefore, the present invention has adopted a kind of mixed diluent of two-pack, promptly adds a spot of monofunctional diluent in the bifunctional thinner.Bifunctional thinner in this mixed diluent can reduce its viscosity under the condition that does not reduce composition epoxy resin intensity.The present invention preferably has the monofunctional diluent of fatty long-chain, as C
12-C
14Alcohol glycidyl ether, C
8-C
10The Fatty Alcohol(C12-C14 and C12-C18) glycidyl ether, the fatty long-chain in its molecule can further improve the toughness of composition epoxy resin; Simultaneously,, can also play to delay the solidified effect, thereby make composition epoxy resin have best set time owing to long-chain is sterically hindered bigger.
In order to improve the surfactivity of fiber reinforcement fabric, the present invention selects the coupling agent of epoxy type for use.The hydroxyl reaction hydrolysis reaction of siloxanes in the coupling agent of epoxy type and fiber reinforcement fabric face, its reaction equation is as follows:
By aforesaid equation as seen, hydrolysis reaction can form the Si-O-C key at the fiber reinforcement fabric face, thereby has improved the boundary strength between fiber reinforcement fabric face and the composition epoxy resin.The preferred coupling agent KH560 of the present invention, the epoxide group on it can react with the amido of B component, thereby increases boundary strength; In addition, company's section of KH560 is a lard type, and its snappiness is better, can increase the intensity of integral composite.
Resins, epoxy and matrix material thereof will contact with oxygen and light in forming process, storage and use inevitably, add variation of temperature, can cause them to change on outward appearance, structure and performance, also occur aging.In order to suppress and slow down the oxidative degradation of macromolecular material, prolong their work-ing life, improve its use value, the present invention adds oxidation inhibitor in resin.Antioxidant of the present invention can be selected from one or more in antioxidant 264, antioxidant 300, antioxidant 1010, antioxidant 1076 and the oxidation inhibitor 168, preferably antioxidant 1010.
The disclosed fiber reinforcement fabric of Chinese invention patent application (application number 200810239439.4) accounts for 60～90% of resin combination weight.But the contriver discovers that fiber reinforcement fabric proportion is low excessively, and the intensity of resin complexes also reduces thereupon significantly.Otherwise, fiber reinforcement fabric too high levels, though the intensity of the resin complexes that obtains promote to some extent, but the pore that can't get rid of will appear in the resin complexes, a little less than the ability that wind resistance hits, can't satisfy the requirement of used for wind power generation blade.Therefore, the present invention is preferred, and the fiber reinforcement fabric accounts for 68～73% of described epoxy resin composite weight, and the ability that epoxy resin composite intensity that obtains thus and wind resistance hit is all good.
The invention has the beneficial effects as follows:
1, utilizes the mixed diluent modified epoxy resin composition, not only be controlled within the reasonable range viscosity and the set time with composition epoxy resin, and improved the toughness and the intensity of composition epoxy resin; Thereby reduced the surface tension of whole composition epoxy resin, strengthened the wetting property of Resins, epoxy and fiber reinforcement fabric.
2, adopt the epoxy type coupling agent, improved the boundary strength between fiber reinforcement fabric face and the epoxy resin composition.
3, preferred content and the high-modulus fiber reinforcement fabric of fiber reinforcement fabric in resin complexes makes the intensity of matrix material and ability that wind resistance hits meet the requirement of used for wind power generation blade fully.
The good mechanical performance of matrix material of the present invention: tensile strength 〉=800MPa, longitudinal stretching modulus 〉=38GPa, unit elongation 〉=1.5%, compressive strength 〉=500MPa, modulus of compression 〉=45GPa, compression elongation 〉=1.2%.
