A melting soaking method comprises the following steps: (1) continuous fiber bundles enter from a fiber inlet (3) and are subjected to pre-dispersing by the tooth-shaped structure (4); and (2) the pre-dispersed continuous fiber bundles penetrate through the group of non-contact soaking rollers (5), then bypass the contact tension rollers (6) in an alternated manner and finally penetrate through the group of non-contact rollers (7), simultaneously a thermoplastic polymer melt is extruded into a melting soaking mold (1) by an extruder connection device connector (2), so that the continuous fiber bundles and the thermoplastic polymer melt can be subjected to melting soaking to obtain a mixed material, and the mixed material is subjected to pulling and cooling to obtain a continuous fiber reinforced thermoplastic resin composite material. The continuous fiber reinforced thermoplastic resin composite material prepared by adopting the device disclosed by the invention is good in soaking effect and excellent in performance.
Description
One, technical field
The present invention relates to continuous fiber reinforced thermoplastic resin composite material, particularly relate to a kind of continuous fiber reinforced thermoplastic resin composite material melt impregnation preparation method.
Two, background technology
Continuous fiber reinforced thermoplastic resin composite material adopts a kind of special immersion system, continuous fiber fully contact, abundant dipping and a kind of one-way fiber of obtaining is arranged and the enhanced type composite material that its length is equal with resin particle length wherein with the thermoplastic resin of molten condition.Thermoplastic resin is uniformly distributed between the fibers, plays the effect of anchoring fiber, transmitted load.It is compared with short fiber reinforced thermoplastic resin, there is intensity high, shock resistance is good, and the exsertile feature of dimensionally stable, heat resistance, is thus widely used in fields such as automobile, space flight, electronic apparatus, plant equipment, weapon industry, construction equipment, furniture and exercises.
, some prepare the immersion system of continuous fiber reinforced thermoplastic resin composite material, such as: be in the Chinese invention patent of CN1037679 and CN101152767A at publication number, the impregnating unit of the melt impregnation device mentioned is generally less, usually single " crest ", " trough " formula curved channel or simple jockey pulley composition is only had, due to the fault of construction of immersion system, continuous tow poor dispersion, damage is large, is difficult to obtain desirable dipping effect.
Three, summary of the invention
The object of this invention is to provide a kind of continuous fiber reinforced thermoplastic resin composite material melt impregnation device.
Continuous fiber reinforced thermoplastic resin composite material melt impregnation device provided by the invention, comprises dentalation (4), noncontact dip roll (5), contact jockey pulley (6) and noncontact roller (7).
In wherein said dentalation (4), two tooth peak level intervals are 20-50mm, and tooth peak is 8-20mm to the vertical interval of tooth paddy; Described noncontact dip roll (5), diameter is 4-10mm, and upper and lower noncontact dip roll intermediate gaps width is 0.5-2mm; Described contact jockey pulley (6), diameter is 4-10mm, and the distance between adjacent two roller horizontal directions is 10-25mm; Described noncontact roller (7), diameter is 4-10mm, and upper and lower noncontact roller intermediate gaps width is 0.5-2mm, and noncontact dip roll (5) is 45-90mm with the level interval of noncontact roller (7).
Provided by the inventionly utilize above-mentioned continuous fiber reinforced thermoplastic resin composite material melt impregnation device to prepare the method for continuous fiber reinforced thermoplastic resin composite material, comprise the steps:
1) continuous tow is entered by fiber entry (3), walk around described dentalation (4), continuous tow is obtained pre-dispersed;
2) by step 1) continuous tow that disperseed is through noncontact dip roll (5) described in a group, again through alternately walking around described contact jockey pulley (6), eventually pass through described noncontact roller (7), simultaneously, melt of thermoplastic polymers is clamp-oned described melt impregnation mould (1) by extruder jockey interface (2), make continuous tow and melt of thermoplastic polymers carry out melt impregnation, obtain continuous fiber reinforced thermoplastic composite material finally by traction cooling.
The step 1 of said method) in, described continuous tow is selected from least one of glass fibre and carbon fiber; Described step 2) in, described thermoplastic polymer is selected from least one in polypropylene, nylon 6, nylon66 fiber, polyformaldehyde.
The present invention adopts dentalation and noncontact dip roll, contact the melt impregnation mould structure that jockey pulley combines, make fibre bundle through repeatedly disperseing and flooding, dentalation provides the first dispersion of fibre bundle, and contact jockey pulley provides twice dispersing, the use of noncontact dip roll, make the two-sided pressurized of fibre bundle dipping process, narrow gap runner, makes melt under Strong shear effect, and viscosity reduces, well permeate combination with processbearing astrocyte, substantially increase the degree of impregnation of fiber.
Compared with prior art, the present invention has the following advantages:
(1) the invention provides melt impregnation device impregnating unit many, provide better dipping and dispersion effect;
(2) traditional melt impregnation mould is generally single " crest ", " trough " formula curved channel or jockey pulley composition.Fibre bundle is when by these curved channels or jockey pulley, and due to one-sided pressurized, fibre bundle can only obtain one-sided dipping, and dipping effect is poor.And except dentalation also contains noncontact dip roll except contacting jockey pulley in melt impregnation mould of the present invention, fibre bundle by dentalation be one-sided dipping when contacting jockey pulley, by being two-sided pressurized when noncontact dip roll and noncontact roller, both sides obtain dipping simultaneously, and thermoplastic polymer resin is when flowing through the narrowed flow path of noncontact dip roll, be subject to Strong shear effect, melt viscosity reduces, and fiber impregnation degree obtains and improves.
Four, accompanying drawing explanation
Fig. 1 is the main pseudosection of continuous fiber reinforced thermoplastic resin composite material melt impregnation device of the present invention;
Fig. 2 is the present invention's contact jockey pulley used vertical cross-section schematic diagram.
Wherein, 1 is melt impregnation mould; 2 is extruder jockey interface; 3 is fiber entry; 4 is dentalation; 5 is noncontact dip roll; 6 is contact jockey pulley; 7 is noncontact roller.
Five, concrete embodiment
Described method is conventional method if no special instructions.Described material all can obtain from open approach if no special instructions.
As shown in Figure 1 and Figure 2, a kind of melt impregnation device preparing continuous fiber reinforced thermoplastic resin composite material, comprises melt impregnation mould (1); Extruder jockey interface (2); Fiber entry (3), bottom is communicated with extruder jockey interface (2); Dentalation (4); Noncontact dip roll (5), 2 symmetrical roller compositions; Contact jockey pulley (6), 3 horizontal roller compositions; Noncontact roller (7), 2 symmetrical roller compositions; A branch of continuous fiber is incorporated in melt impregnation mould (1) by fiber entry (2); This bundle continuous fiber walks around dentalation (4); By the space of noncontact dip roll (5); Involve after alternately walking around 3 contacts jockey pulley (6); Polymer melt enters melt impregnation mould (1) by extruder jockey interface (2); One-sided dipping is there is by the curved channel of dentalation (4) and fiber; Then, polymer melt flows through noncontact dip roll (5), because melt is subject to the stop of roller, produce backflow and eddy flow, the intensive shear effect of minimum roll gap generation in addition, makes melt viscosity decline, and from both sides press-in fibrous inside, make fibre bundle obtain double-steeping; Then, melt flows through the one-sided dipping that contact jockey pulley (6) creates again fiber, adds degree of impregnation; Afterwards, melt flows through the final dipping that noncontact roller (7) completes fiber; Finally by the pellet of continuous fiber reinforced thermoplastic resin composite material cooling, draw, be cut into certain length.
