Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Fig. 1 is the structural representation of a kind of textuered yarn long fiber reinforced plastics material grain of the present invention;
Fig. 2 is the schematic flow sheet of the working method of a kind of textuered yarn long fiber reinforced plastics material grain of the present invention; Fig. 3 is the loose synoptic diagram of yarn principle of the dipping head uses in the working method of a kind of textuered yarn long fiber reinforced plastics material grain of the present invention diffusing knot structure.
At first, with reference to Fig. 1 textuered yarn long fiber reinforced plastics material grain of the present invention is described, material grain of the present invention comprises: plastic substrate 1 strengthens macrofiber with textuered yarn, and wherein textuered yarn enhancing macrofiber comprises two portions: a heart yarn 2 and a layer yarn 3.The parallel axes of heart yarn 2 and plastic substrate 1 is evenly distributed in the inside of plastic substrate, layer yarn 3 is loose be distributed in heart yarn 2 around, and guarantee that overall edge stretches the axial consistent of direction and plastic substrate 1.
As a kind of preferred version, layer yarn 3 demonstrates form curling, spiral round heart yarn 2, can realize that so layer yarn 3 all has distribution in the three-dimensional scope of spatial, effectively improved the unicity of fiber reinforcement direction.
As a kind of preferred version, it is the voluminous yarn fiber that textuered yarn strengthens macrofiber.The voluminous yarn fiber is under the situation of heating, because the shrinking percentage difference can realize the structure and the form of above-mentioned heart yarn 2 and layer yarn 3.
Carry out bright specifically below in conjunction with Fig. 2, Fig. 3 to the working method of a kind of textuered yarn long fiber reinforced plastics material grain of the present invention.
Working method of the present invention comprises following flow process:
Flow process a: the plastic matrix material is sent into forcing machine carry out heating plasticizing; The molten plastic of heating plasticizing formation is expressed into the dipping head then.In this flow process, mainly be that the plastic matrix material is processed into liquid stream so that follow-up being expressed in the dipping head.
As preferred version, forcing machine adopts single screw extrusion machine; Can reduce engineering cost relatively like this.
Flow process b: the yarn bundle of textuered yarn is sent to the dipping head, and textuered yarn is melted in the dipping head and is extruded as the material bar in the lump after plastics fully flood, wrap up.
As a kind of preferred version,, the yarn bundle of textuered yarn carries out preheating before getting into the dipping head.
In this flow process,, as shown in Figure 3 as a kind of preferred version; At the dipping head fusiform diffusing knot structure 4 more than is set, the yarn bundle of textuered yarn 5 gets into the part that runs into fusiform middle protrusion from a fusiform end, under the tensile effect; On the circumferential direction of knot structure 4 intermediate projections that looses, disperseed; Fully flooded by middle molten plastic under the textuered yarn 5 dispersive states, and the dipping head has certain processing temperature and makes shrinking percentage is big in the textuered yarn 5 a part form heart yarn, a part of form layers yarn that shrinking percentage is little; Finally from the extrusion moulding of dipping head the time, formation is whole extrudes the textuered yarn enhancing macrofiber that direction is extended along the material bar.
Flow process c: the material bar at first cools off under the traction of towing mechanism, passes through the process that the air knife device carries out air blast cooling and removes surperficial moisture content then, sends into dicing machine then and carries out pelletizing, at last the material grain is collected.
As a kind of preferred version, as shown in Figure 2, before pelletizing, can carry out rolling, pelletizing then to the material bar earlier; It is the off-line pelletizing.
As a kind of preferred version, textuered yarn can adopt voluminous yarn.
Utilize method of the present invention, can effectively realize the dispersion of textuered yarn fortifying fibre, make can being dispersed in uniformly in the material grain of textuered yarn fortifying fibre, in addition,, improved the performance of material grain because textuered yarn is met heat and can be deformed in the course of processing.
