Abstract
The utility model relates to a device for preparing a long fiber reinforced polypropylene composite sheet. The device comprises a screw extruder, a fiber yarn frame, an extruding mouth mold and a double steel-strip press, wherein a material inlet is formed in one end of the screw extruder; the screw extruder is connected with the fiber yarn frame through a fiber inlet; an extruding mouth of the screw extruder is connected with an inlet of the extruding mouth mold; and an outlet of the extruding mouth mold is connected with the double steel-strip press.
Description
Technical field
The utility model relates to a kind of device for preparing the long fibre enhanced polypropylene composite sheet.
Background technology
Long fiber reinforced thermoplastic composites is a kind of Novel lightweight material of fibre reinforced thermoplastic polymer field of compound material, has the characteristics such as designability, low-density, high specific strength, high ratio modulus and high impact properties.Adopting the long fiber reinforcement technology is one of important technology approach that improves the thermoplastic polymer performance.
Fibre length is longer in long fiber reinforced thermoplastic composites, and is evenly distributed, and can form three-dimensional net structure in the thermoplastic resin matrix, thereby can improve the comprehensive mechanical property of moulded products, and particularly impact strength can be able to significantly improve.The mechanical property of materials obviously is better than the thermoplastic composite that short fiber strengthens, and the moulding processing characteristics is better than GMT, its goods can be by technological formings such as compression moldings, can be used for the very complicated member of forming shape, be with a wide range of applications in industries such as automobile and other vehicle manufacturing, building, packing, household electrical appliances.This material is alternative metals or same with thermosetting compound material effectively, can effectively reduce weight and the manufacturing cost of goods.Therefore, provide a kind of simple and easy, stable composite sheet device to become the problem of needing solution badly.
The utility model content
The purpose of this utility model provides a kind of device for preparing the long fibre enhanced polypropylene composite sheet, can steady production long fibre enhanced polypropylene composite sheet.
Concrete technical scheme is as follows:
A kind of device for preparing the long fibre enhanced polypropylene composite sheet, comprise a screw extruder, fiber creel, extrusion neck ring mold and double-steel belt pressing machine, screw extruder one end is provided with a material inlet, this screw extruder advances fine mouthful by one and connects with the fiber creel, this screw extruder extrusion is connected with the extrusion neck ring mold import, and the outlet of extrusion neck ring mold is connected with double-steel belt pressing machine.
Further, this device comprises that also a board cutting device is arranged at after the double-steel belt pressing machine.
The utility model apparatus structure is simple, is convenient to implement, and the long fibre enhanced polypropylene composite sheet of volume production moulding that can be stable has satisfied the demand of producing the long fibre enhanced polypropylene composite sheet steady in a long-term that needs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
See also Fig. 1, the device of described preparation long fibre enhanced polypropylene composite sheet comprises screw extruder 2, fiber creel 4, extrusion neck ring mold 5, double-steel belt pressing machine 6 and board cutting device 7.Screw extruder 2 one ends are provided with a material inlet, and this screw extruder 2 advances fine mouthful 3 with 4 connections of fiber creel by one, and the extrusion of this screw extruder 2 is connected with extrusion neck ring mold 5 imports, and the outlet of extrusion neck ring mold 5 is connected with double-steel belt pressing machine 6.This device comprises that also a board cutting device is arranged at after the double-steel belt pressing machine 6.
During use, the material 1 that mixes comprises that the function additives such as polypropylene, compatilizer, antioxidant, colouring agent add from the hopper of twin-screw extrusion 2.Fiber on the fiber creel 4 enters double screw extruder 2 for fine mouthful 3 from advancing of double screw extruder 2 stage casings, and with material 1 evenly blend in double screw extruder 2 machine barrels of melting.After the blend, be transported to the extrusion die 5 at double screw extruder 2 head places, form TRPP sheet material blank.TRPP sheet material blank is the final TRPP sheet material that obtains under the effect of double-steel belt pressing machine 6 subsequently, and double-steel belt pressing machine 6 also has the effect of traction simultaneously.The TRPP sheet material that obtains cuts into the length that needs along with double-steel belt pressing machine 6 is transported to board cutting device 7 places, and namely the TRPP sheet material 8 of fixed length is convenient to processing, packing and transportation.
Being the preferred embodiment of utility model only in sum, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
