Abstract
The invented equipment is composed of unrolling device, guiding device, leveling device, coating chamber, fusion furnace, regulating device, static electricity device, resin content test system, drawing device, roll collecting device, recovery device, control system, and compressed air source. The presoaked fabric passes through the coating chamber of static electricity charged resin powder, the double surfaces are coated with resin powder, then the coated fabric is smoothed through the high temp of fusion furnace, the resin is adhered on the presoaked fabric. In order to make the impregnation be level and uniform, the whole impregnation course is checked and controlled by a beta ray instrument and a computer, said equipment is suitable for the thermosetting resin and thermoplasticity resin.
Description
The present invention relates to a kind of thermoplasticity and thermosetting resin electricity preliminary dip treatment equipment and process.
In recent years, the research of a series of preimpregnation equipment and process has been carried out in preparation around the thermoplastic resin prepreg, comprise melt impregnation, solution impregnation, fiber hybrid dipping, powder impregnation, suspension dipping, static impregnating, they are all existing the suitable solvent of shortage in varying degrees, the resin heated time is long, remove difficulty of moisture content and emulsifying agent, the inhomogeneous smooth deficiency that waits in impregnate layer surface.What the disclosed fluid bed impregnation technologies of dutch patent specification IIM 861464 adopted is powder impregnation, it be utilize toner on pre-soaking fiber deposition and adhere to and obtain prepreg.But it exists toner equally and adheres to inequality, and the prepreg resin content precision is restricted.
The objective of the invention is, a kind of electrostatic powder dipping that utilizes is provided, make the prepreg outward appearance evenly smooth, do not have rich resin region and resin starved region, fiber is parallel to each other, electricity preliminary dip treatment equipment that resin content is stable and process.
Technical solution of the present invention is that electricity preliminary dip treatment equipment is by decoiling equipment 1, guider 2,6,9,10, flattening device 3,4,5, coating room 7, melting furnace 8, adjusting device 11, measurement test system 12, draw-gear 13, wrap-up 14, electrostatic equipment 15, control system
Retracting device 17, compressed air source 18 are formed.
A. decoiling equipment is made of a roller, can lay the preimpregnation fabric of width less than the 400mm all size, adopts the exciting curent tension regulator, guarantees tension force substantially constant in the technical process, and fabric operates steadily.
B. flattening device is made up of the array roller, to flatten fabric.
C. coating room adopts the electrostatic powder dual coating to the preimpregnation fabric, and indoor battery lead plate, compressed air inlet, static chamber, powder material chamber and the Powder Recovery of being provided with exports, and the operating voltage of coating room is 0～90 kilovolt.
D. the effect of melting furnace is to make resin fusing and stick on the fabric, and for making the resin also permeable fiber that as far as possible evenly distributes, the operating temperature of melting furnace is 0～600 ℃.
E. draw-gear is the power of full machine, adopts rubber rollers.
F. wrap-up utilizes the software feature of alternating current torque motor to guarantee tension force and linear velocity substantially constant in the wrapup procedure, contains the photoelectric error correction device in the device, batches the displacement of roller in order to adjusting.
G. compressed air source is provided by 3W～1.6/10B-1 air compressor, and enters coating room after purifying.
H. the resin content test macro has a β alpha cellulose a gage, utilize the prepreg absorbed number of the beta ray source of fixed dosage through different resins content, and on the microcomputer curtain, demonstrate the respective change of signal, when resin content surpasses preset range,, microcomputer control executing agency changes resin content thereby changing the pressure of pressure charging system.
I. control system mainly is by technological parameters such as the content of microcomputer control resin and linear velocity, rolling quality, uncoiling tension, melting furnace temperature, motion correction, atomizing pressures.
Advantage of the present invention is, adopt the high-voltage electrostatic field to make the charged and dual coating of toner, the closed loop automatic control system that β alpha cellulose a gage and microcomputer form makes the resin content of prepreg even, fluctuation range is little, surfacing, composite property conversion ratio height, solvent-free recovery problem, be applicable to that cloth is wide less than 400mm, thickness 0.08～0.25mm, the continuous fabric of length, resin content is 25～45% controlled, and precision is ± 3%, and powder size is 5～200 μ.
