Abstract
The utility model discloses a continuous fiber reinforced polypropylene foamed board which comprises a continuous fiber-based composite material layer and PP (polypropylene) foamed boards formed by means of vacuum hot-pressing. The continuous fiber reinforced polypropylene foamed board can solve the technical problem of methods for enabling foamed boards to have good physical performances.
Description
Technical field
The utility model relates to a kind of foaming plate, a kind of specifically continuous fiber RPP foaming plate.
Background technology
Foaming plate since its relatively other sheet material such as solid wood board have lot of advantages such as in light weight etc.; Make and be widely used in the daily life; Traditional foam process such as screw rod extrude or injection foaming owing to when implementing process, touch air constantly, thereby make temperature can not pass to the polypropylene of even mixed foaming agent uniformly, thereby make that the thickness of the second-rate of foaming and foaming is also thinner; Like 5mm, thicker thickness can't foam.In addition, present foaming plate is owing to be one deck structure, and it does not have very strong physical property, and like bending strength, hot strength and impact strength etc., this has brought certain restriction to use.
The utility model content
The purpose of the utility model provides a kind of continuous fiber RPP foaming plate, solves how to make foaming plate have the technical problem of good physical property.
The utility model solves the technical scheme that its technical problem adopted:
Continuous fiber RPP foaming plate comprises continuous fiber based composites layer and the PP foaming plate that adopts vacuum hotpressing to form.
Said continuous fiber based composites layer is two-layer, and PP foaming plate is located at this and forms three-decker between two-layer.
Said continuous fiber based composites is flooded in the molten thermoplastic resin by continuous fiber and obtains.
Said in the continuous fiber based composites, by weight, continuous fiber is 10-70%, thermoplastic resin is 30-90%.
Said thermoplastic resin is a polypropylene.
Said continuous fiber is inorfil or organic fiber or metallic fiber.
Said inorfil is a glass fibre.
The thickness of said PP foaming plate is 0-40mm.
The thickness of said PP foaming plate is 20 mm.
Continuous fiber based composites layer is 10-50 mm.
The beneficial effect of the utility model is: clamp such three-decker that PP foaming plate forms because foaming plate has become two-layer continuous fiber based composites by original one deck structure; And PP foaming plate is because through vacuum hotpressing; Its thickness can reach 40mm; This makes the sheet material that processes at last have very strong physical property, like bending strength, hot strength and impact strength etc., thereby improves its application performance.

The specific embodiment
Please refer to Fig. 1; This foaming plate has three-decker, outmost two-layer be continuous fiber based composites layer 15, the inside be PP foaming plate 14; The PP foaming plate that shows among Fig. 1 is for block; Because adopt vacuum hot pressing technique, it can reach 40mm, traditional foaming technique can only reach 5mm.Certainly can change the dull and stereotyped die cavity in the flat plate mold among Fig. 3 10 into other xenotype mold as required, so just can make Different products, like the helmet, seat, furniture etc.
Please refer to Fig. 2 and Fig. 3, continuous fiber RPP foaming plate former comprises hot press 9, flat plate mold 10, mold fixed plate 11, makes the PP GRANULES 13 in the mould be in permeation-proof air film 12 or vavuum pump under the vacuum environment; Permeation-proof air film 12 or vavuum pump are fixed on the flat plate mold 10, and flat plate mold 10 is fixed in the hot press 9 through mold fixed plate 11.During making above-mentioned fiberglass-based composite material sheet 8 is arranged in the upper and lower surface of flat plate mold 10, fills the PP GRANULES 13 of even mixed foaming agent in the middle of the sheet material; Flat plate mold 10 is put into hot press 9 uses high temperature permeation-proof air film 12 or vavuum pump to carry out vacuum hotpressing; Do not contact with air; The heating-up temperature of hot press 9 is the 180-350 degree; Be 5-30 minute heat time heating time, temperature is delivered in polypropylene 2 particles uniformly makes its foaming, and 9 carry out cooling processing with mould and get final product after the hot pressing.
Please refer to Fig. 4; The preparation method of fiberglass-based composite material sheet is: at first both direction is drawn from creel respectively like the glass fibre 1 of the both direction that becomes parallel or angle of inclination; Behind godet, branch silk paper tinsel; Through the tension force of pulling roll control glass fibre, guarantee when it is drawn stability be arranged in parallel.After drawing the glass fibre 1 of second direction is caused on the surface of glass fibre 1 of first direction; The above-mentioned ground glass fibre 1 that mixes is sent into preheating oven 3 preheatings; Glass fibre 1 is through after the preheating; Extrusion die 5 on the first dipping tank 4 is extruded the glass fibre 1 of one molten resin after to preheating through the first molten resin passage 6 and is tentatively flooded, and another extrusion die 5 with last die head relative direction carries out flooding the second time to the glass fibre 1 through preliminary dipping through second road molten resin passage 7 resin melt extrusions degree of impregnation is reached more than 90% then; The fiberglass-based composite material sheet that forms after the 1 process hot pressing roller hot pressing of dipping back glass fibre carries out cooling processing, realizes the cooled and solidified of molten resin, forms multiaxis to strengthening the thermoplasticity stator.In practical application, can select the different successive fiber for use according to different needs, continuous fiber can be selected arbitrarily from inorfil, organic fiber, metallic fiber, and thermoplastic resin raw materials also can be selected other material for use, like PA etc.
