Summary of the invention:
The present invention proposes the pre-compound method for preparing the performance resins based nano composite material of inorganic nano-particle/continuous fibre first, and namely pre-complex method, exactly in preparing unsaturated polyester resin base glass fiber reinforced plastics product, material modified (as nanometer SiO to what add
2, nano-OMMT, carbon fiber etc.) carry out pre-treatment, make before the unsaturated polyester resin curing molding nano-OMMT powder evenly be sprayed on glass fibre weaves cotton cloth, reach the finely dispersed effect of nanoparticle, and do not increase the viscosity of resin, with multilayered structure and the collaborative strengthening and toughening mechanism of of inorganic nano-particle/continuous fibre of this further investigated resin-base nano matrix material, to solve the fundamental problems of application of the collaborative highly malleablized resin-base nano matrix material of inorganic nano-particle/continuous fibre.
Patent design of the present invention a kind of pre-set composite, this covering device is comprised of unwinding equipment 1, nanoparticle jet apparatus 2, retrieving arrangement 3, heating unit 4 and crimping device 5.
Unwinding equipment 1 and crimping device 5, finally need crimping device to realize continuous operation through the glasscloth sprayed by heating unit.The device left end is connected with undressed glasscloth by cylinder, and the device right-hand member is connected with motor, and by the driven by motor belt transmission, the glasscloth so just made is curling at the device right-hand member with constant speed, completes the whole pre-compound processing of dusting.
Nanoparticle jet apparatus 2, in pre-set composite, according to the operation rule of spray gun, nozzle maintains static in airtight dusting device, the glasscloth uniform motion.
Retrieving arrangement 3, powder coating generally spray in airtight or semi closed space, the physical and chemical performance of powder is stable, has determined that powder can reuse in spraying process, is environmentally friendly coating.Powder spraying chamber may be defined as sealing or semi-enclosed, be difficult for gathering powder, have good mechanical ventilate excessive powder, and can effectively will not be coated with the chamber body or the building enclosure that are specifically designed to electrostatic powder spraying that powder imports retrieving arrangement.
Heating unit 4, the glasscloth sprayed need to carry out drying treatment through heating system, will make like this OMMT powder complete wetting in glasscloth, reaches desirable spraying effect.Electric heating can require to arrange different Electric heating according to workpiece more flexibly, and this device adopts the hot plate heating.
The present invention proposes a kind of novel method and equipment for preparing the resin-base nano matrix material, this method and equipment can not increase the viscosity of resin, and nano material is dispersed in resin matrix, improve its mechanical property, resistance toheat and some function that increases are (if conducted electricity, heat conduction etc.), and with traditional method, compare the viscosity that does not increase resin, be conducive to flowing of resin, thereby plastic wind power generation blade, the large-sized structural parts such as aircraft skin, this project combines Materials science and advanced manufacturing technology, intersection and the development of each related discipline have been promoted, dispersed for nano material, the preparation of resin-base nano matrix material and application provide new technique means and theoretical basis, have very important theory significance and engineering using value.
Its algorithm is by electric machine rotation, to drive glass fibre to move ahead, and dusting device evenly is sprayed on nano imvite on the glass fibre cord, and following recovery pump will be sprayed on the outer powder of glass fibre cord and reclaim.Travelling belt will drive glasscloth and at the uniform velocity advance, and the heating of glasscloth process hot plate makes the polynite powder fully evenly to soak into and by the cylinder crimping device, received afterwards.The final like this glasscloth that is sprayed with nanoparticle prepares complete, can carry out the industrialized production application of large-scale.

Fig. 1 is pre-composite monolithic structure drawing of device.
Embodiment:
In order to make the object of the invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, apparatus of the present invention are further elaborated.The present invention relates to pre-compound preparation facilities, the modal glass fiber reinforced plastics product of below take is told about apparatus of the present invention specific implementation process as embodiment.
Device left end unwinding equipment 1 is connected with undressed glasscloth, device right-hand member crimping device 5 is connected with motor, by the driven by motor transmission, the glasscloth so just made is curling at device right-hand member crimping device 5 with constant speed, completes the whole pre-compound processing of dusting.The glass fibre cord is fixed on left end unwinding equipment 1 through the motor-driven on right-hand member crimping device 5, in dusting device 2, complete and dust, residual powder is by retrieving arrangement 3 recyclings, and the glass fibre cord after having been dusted by 4 pairs of heating units after having dusted carries out heat treated.Will make like this OMMT powder complete wetting in glasscloth, reach desirable spraying effect.Finally by right-hand member crimping device 5, complete the pre-Combined Processing that the glass fibre cord dusts.
