Abstract

The utility model discloses a bamboo rib wound plastic composite pipe which belongs to the field of pipes. A traditional composite pipe has high manufacturing cost. The bamboo rib wound plastic composite pipe is characterized in that a plurality of spiral bamboo ribs are distributed in a middle layer to reinforce the strength of the composite pipe, and fewer materials are sued and the cost is lower compared with a traditional structure with a metal layer as the middle layer; furthermore, single bamboo ribs are connected into a long rib from wrapping layers outside, thereby continuously wrapping the single bamboo ribs on a plastic inner layer and facilitating manufacturing; and the middle layer is a hot melt adhesive layer, thereby facilitating the positioning of the bamboo ribs wound on the plastic inner layer when in manufacturing, ensuring that the bamboo ribs are uniformly distributed in the inner layer, so that all parts of the composite pipe have consistent strength.

Description

Bamboo reinforcement winding plastic composite pipe

Technical field

The utility model belongs to pipe, specifically is a kind ofly to strengthen the bamboo reinforcement winding plastic composite pipe of the intensity of composite pipe by stiffening rib is set in the mesosphere.

Background technique

Mostly existing composite pipe is composite metal-plastic pipe, promptly constitute by inner plastic, metal intermediate layer, plastic outer layer, but since Metal Distribution in whole mesosphere, so materials are many, the manufacture cost height of composite pipe.

The model utility content

The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the existing high defective of composite pipe manufacture cost, and a kind of bamboo reinforcement winding plastic composite pipe is provided.For this reason, the utility model is by the following technical solutions:

Bamboo reinforcement winding plastic composite pipe comprises inner plastic, mesosphere, plastic outer layer, it is characterized in that some helical bamboo reinforcements that distribute in the described mesosphere.

As the optimization technique measure, single bamboo reinforcement is linked to be long muscle by being wrapped in the outer coating of bamboo silk.

As the optimization technique measure, the helix angle of bamboo reinforcement is 10 °～80 °.

As the optimization technique measure, the mesosphere is a heat-fusing glue layer.

The beneficial effects of the utility model are:

1, composite pipe intensity is strengthened in the mesosphere that the helical bamboo reinforcement is distributed in composite pipe, and with respect to the structure of using metal layer as the mesosphere in the past, materials are economized, and cost is low.

2, single bamboo reinforcement is linked to be long muscle by being wrapped in its outer coating, is beneficial to continuously single bamboo reinforcement is wrapped on the inner plastic, is convenient to make.

3, the mesosphere is a heat-fusing glue layer, to being wrapped in the bamboo reinforcement location on the inner plastic, guarantees that bamboo reinforcement is evenly distributed in internal layer in being convenient to make, and makes each position of composite pipe have consistent intensity.

Description of drawings

Fig. 1 is the cross-sectional configuration schematic representation of the utility model bamboo reinforcement winding plastic composite pipe.

Fig. 2 is that the tube wall of the utility model bamboo reinforcement winding plastic composite pipe flattens schematic representation.

The number in the figure explanation: the 1-inner plastic, the 2-mesosphere, the 3-plastic outer layer, the 4-bamboo reinforcement, the helix angle of β-bamboo reinforcement, o-o-composite pipe center line, S-S-is perpendicular to the plane of composite pipe center line.

Embodiment

Below in conjunction with Figure of description the utility model is described further.

Bamboo reinforcement winding plastic composite pipe of the present utility model, as shown in Figure 1, 2, it comprises inner plastic 1, mesosphere 2, plastic outer layer 3, characteristics are that the some helical bamboo reinforcements 4 of distribution are strengthened composite pipe intensity in the mesosphere 2, with respect to the structure of using metal layer as the mesosphere in the past, materials are economized, and cost is low.

As further improving and replenishing to technique scheme, the utility model also comprises following additional technical characteristics, though Fig. 1,2 has comprised following additional technical feature, it is preferred embodiment of the present utility model, but the utility model is not limited to this situation, according to specifically acting on they is selected for use on the described technological scheme of epimere when implementing the utility model:

In view of the bamboo silk of making bamboo reinforcement 4 is from being processed by bamboo, its length is generally 3～5 meters, be not easy to be wrapped in the bamboo silk on the inner plastic continuously when making composite pipe, therefore single bamboo reinforcement is linked to be long muscle by being wrapped in the outer coating of bamboo silk, be beneficial to continuously and be wrapped on the inner plastic, be convenient to make single.

The helixangle of bamboo reinforcement (referring to Fig. 2, bamboo reinforcement 4 and angle perpendicular to planar S-S of composite pipe center line o-o when helixangle is defined as the tube wall of the utility model bamboo reinforcement winding plastic composite pipe flattened) is 10 °～80 °.The intensity that can reach is as required selected suitable helixangle.

Mesosphere 2 is a heat-fusing glue layer, to being wrapped in the bamboo reinforcement location on the inner plastic, guarantees that bamboo reinforcement is evenly distributed in internal layer in being convenient to make, and makes each position of composite pipe have consistent intensity.

During manufacturing, make inner plastic (as by the extruder extrusion molding) earlier; To be wrapped in the outer wall of inner plastic by the some single bamboo reinforcement that coating is linked to be long muscle according to the helixangle of setting afterwards; Then form (as by the extruder plastic squeeze) mesosphere and bamboo reinforcement is included in the mesosphere in the inner plastic outside; Form plastic outer layer (as by the extruder extrusion molding) at last in the outside, mesosphere.
