The PVC wood plastic inner co-extrusion door pocket solves the technical problem that the existing PVC wood plastic door pocket is poor in comprehensive mechanical property, and achieves conversion of PVC wood plastic application from a decorative material to a structural material.
The technical scheme in the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
the embodiment of the utility model comprises an outer layer co-extrusion layer and an inner core co-extrusion layer which are formed by fusion co-extrusion, wherein the toughness of the inner core co-extrusion layer is larger than that of the outer layer co-extrusion layer; clamping grooves are respectively formed in two sides of the outer layer co-extrusion layer, and the outer layer co-extrusion layer is fixedly connected with adjacent door pocket lines through the clamping grooves; the inner core co-extrusion layer is positioned in the outer layer co-extrusion layer and is arranged at least at one side of the outer layer co-extrusion layer close to the lockhole edge or the joint edge. The toughness and the strength of the whole door pocket lockhole edge and the hinge edge are improved, repeated switching vibration in the later period is resisted, the whole nail holding force is enhanced, and further the conversion of PVC wood plastic application from a decorative material to a structural material is realized.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Examples:
as shown in fig. 1-2, the embodiment of the utility model provides a PVC wood-plastic inner co-extrusion door pocket, which comprises an outer co-extrusion layer 10 and an inner co-extrusion layer 20 formed by fusion co-extrusion, and specifically, the two layers are fused by adopting the existing inner co-extrusion process.
For the outer co-extrusion layer 10, that is, the common PVC wood-plastic door pocket has lower toughness and strength, in the embodiment of the present utility model, the toughness of the inner core co-extrusion layer 20 is greater than that of the outer co-extrusion layer 10, and specifically, PP or PVC materials added with toughening agents can be adopted, wherein, considering better fusion effect of the same material, the PVC materials added with toughening agents are preferably selected.
It should be emphasized that the toughening agent may be any one or combination of the elastomer toughening agent or the blending toughening modification with the rigid particles in the prior art according to actual needs, and is not limited herein.
As shown in fig. 2, two sides of the outer co-extrusion layer 10 are respectively provided with a clamping groove 101, and the outer co-extrusion layer 10 is fixedly connected with adjacent door pocket lines through the clamping grooves 101.
In order to reduce the cost, under the condition of ensuring the normal use requirement of the product, a middle partition 102 can be further arranged inside the outer layer co-extrusion layer 10; the cross-sectional shape of the septum 102 may be rectangular or circular.
As shown in fig. 2, the inner core co-extrusion layer 20 is located inside the outer layer co-extrusion layer 10, and is disposed at least on one side of the outer layer co-extrusion layer 10 near the keyhole edge or the hinge edge, so as to improve toughness and strength of the keyhole edge and the hinge edge of the whole door pocket, and resist repeated switching shock in the later period.
In order to further enhance the overall nail-holding force, the screw can be repeatedly disassembled and screwed. As shown in fig. 2 to 3, the inner core co-extrusion layer 20 is designed into a double-layer i shape according to the embodiment of the present utility model.
In addition, as shown in fig. 2 to 3, the cross section of the inner core co-extrusion layer 20 is set to a canine shape, which increases the contact surface of the wood plastic material, preventing the outer layer co-extrusion layer 10 from layering.
From the analysis, the overall toughness, nail holding force, strength and other comprehensive mechanical properties of the PVC wood-plastic inner co-extrusion door pocket are superior to those of the common PVC wood-plastic door pocket, which is equivalent to the increase of the application range of PVC wood-plastic and the conversion of the application of the PVC wood-plastic inner co-extrusion door pocket from a decorative material to a structural material is realized.
In summary, compared with the prior art, the method has the following beneficial effects:
the embodiment of the utility model comprises an outer layer co-extrusion layer and an inner core co-extrusion layer which are formed by fusion co-extrusion, wherein the toughness of the inner core co-extrusion layer is larger than that of the outer layer co-extrusion layer; clamping grooves are respectively formed in two sides of the outer layer co-extrusion layer, and the outer layer co-extrusion layer is fixedly connected with adjacent door pocket lines through the clamping grooves; the inner core co-extrusion layer is positioned in the outer layer co-extrusion layer and is arranged at least at one side of the outer layer co-extrusion layer close to the lockhole edge or the joint edge. The toughness and the strength of the whole door pocket lockhole edge and the hinge edge are improved, repeated switching vibration in the later period is resisted, the whole nail holding force is enhanced, and further the conversion of PVC wood plastic application from a decorative material to a structural material is realized.
