Example Embodiment

[0036] Example one:

[0037] In the first embodiment, the first polyolefin tube is a PP (Polypropylene, polypropylene) tube, and the second polyolefin tube is a TPV (Thermoplastic Vulcanizate, thermoplastic vulcanizate) tube. The plastic coolant pipe in the first embodiment is The order to the outside is: PP layer, TPV layer. PP material has good performance of coolant resistance and temperature resistance. TPV material not only has the stiffness and excellent processing performance of plastic, but also the flexibility of rubber material.

[0038] During processing, PP material and TPV material can be added to the multi-composite extruder for extrusion, and a certain extrusion temperature can be controlled to form a double-layer tubular structure.

Example Embodiment

[0039] Embodiment two:

[0040] In the second embodiment, the first polyolefin tube is a HDPE (High Density Polyethylene, high-density polyethylene) tube, the second polyolefin tube is a TPV tube, and the first polyolefin tube and the second polyolefin tube are also adhesive. The binding agent layer group, the plastic cooling liquid water pipe in the second embodiment of the present invention is, from the inside to the outside, the HDPE layer, the adhesive layer, and the TPV layer. HDPE material has good heat resistance and cold resistance, and also has high rigidity and toughness.

[0041] The adhesive layer group can strengthen the connection strength between HDPE and TPV. In this embodiment, the adhesive layer group is a layer of plastic material that serves as an adhesive.

[0042] During processing, HDPE materials, binders and TPV materials can be added to the multi-composite extruder for extrusion, and a certain extrusion temperature can be controlled to form a multilayer tubu...

Example Embodiment

[0043] Embodiment three:

[0044] In the third embodiment, the first polyolefin tube is an HDPE tube, the second polyolefin tube is a TPV tube, and there is an adhesive layer group between the first polyolefin tube and the second polyolefin tube. The adhesive layer group includes a first adhesive layer and a second adhesive layer, and a barrier layer is also provided between the first adhesive layer and the second adhesive layer. Adding a barrier layer between the first adhesive layer and the second adhesive layer can make the plastic coolant water pipe have better tensile strength and anti-aging performance.

[0045] Wherein, the barrier layer may be an EVOH (Ethylene vinyl alcohol copolymer) tube, a PA6 (nylon 6) tube or other barrier material layer. The plastic cooling liquid water pipe in the third embodiment is: HDPE layer, adhesive layer, EVOH / PA6 layer, adhesive layer, and TPV layer from inside to outside.

[0046] During processing, the HDPE material, each layer of binder, ...

Abstract

The invention provides a plastic cooling liquid water pipe and a preparation method thereof, relating to the technical field of cooling pipes. The plastic cooling liquid water pipe comprises a first polyolefin pipe and a second polyolefin pipe, wherein the first polyolefin pipe is coated with the second polyolefin pipe, and when the first polyolefin pipe and the second polyolefin pipe are made ofthe same material, a reinforcing layer is further arranged between the first polyolefin pipe and the second polyolefin pipe. The plastic cooling liquid water pipe provided by the invention can be recycled, is light in weight, low in cost and low in permeability, and more conforms to the development trend of a safe, environment-friendly and weight-reducing whole vehicle.

Description

technical field [0001] The invention relates to the technical field of cooling pipes, in particular to a plastic cooling liquid water pipe and a preparation method thereof. Background technique [0002] With the development of new energy vehicles in recent years, the pipeline of the coolant system inside the vehicle has also undergone great changes. [0003] Recyclable materials, lightweight, hydrolysis resistance, and low volatile permeation will inevitably become the development trend of future coolant pipelines. There are three major cooling panels in the vehicle, which are the motor system or engine system cooling pipeline in the front cabin, the chassis coolant transmission pipeline and the battery cooling pipeline. The chassis coolant transmission pipeline and battery cooling pipeline are now made of plastic pipelines as the main material structure, which can meet the requirements of light weight, low volatile permeation and unique space layout. The choice of materia...
