Example 2
A water sucking device with a variable pipe diameter is a spiral water sucking pipe, and the structure of the water sucking device is the same as that of the water sucking device in the embodiment 1.
The pressure sensitive adhesive layer is made of a thermoplastic elastomer-based material and comprises the following raw materials in parts by weight: 100 parts of SBS, 30 parts of four-needle-shaped nano zinc oxide, 40 parts of nano superfine argil, 5 parts of dioctyl phthalate, 10 parts of terpene phenolic resin, 5 parts of C5 petroleum resin, 10 parts of coumarone resin, 1 part of PX anti-aging agent and 1 part of aniozaid L122 anti-aging agent.

Example 3
A water sucking device with a variable pipe diameter is a spiral water sucking pipe, and the structure of the water sucking device is the same as that of the water sucking device in the embodiment 1.
The pressure sensitive adhesive layer is made of a thermoplastic elastomer-based material and comprises the following raw materials in parts by weight: 50 parts of SBS, 50 parts of SIS, 40 parts of four-needle-shaped nano zinc oxide, 30 parts of nano superfine kaolin, 5 parts of dioctyl terephthalate, 10 parts of terpene resin, 10 parts of C9 aromatic hydrocarbon petroleum resin, 1 part of BZ antioxidant and 1 part of Antiozard L122 antioxidant.

Comparative example 2
The comparative example has the same structure as the water absorption pipe of example 1, except that 70 parts of nanometer ultrafine kaolin are selected as the nanometer particles in the pressure sensitive adhesive layer.
TABLE 1 Performance of pressure-sensitive adhesive layers of examples and comparative examples
As can be seen from Table 1, the addition of the tetrapod-like nano zinc oxide into the pressure-sensitive adhesive layer can reduce the Mooney viscosity of the pressure-sensitive adhesive layer and improve the tensile strength and the peel strength of the pressure-sensitive adhesive layer.
TABLE 2 spiral suction hose performance (DN 150)
As can be seen from Table 2, the spiral water suction pipe with the pipe diameter of 150mm is produced, compared with the spiral water suction pipe produced in the comparative example 1, the pipe diameter of the spiral water suction pipe produced conventionally has no variability and has larger error, and the adaptability to the water suction accessory is correspondingly poor. However, the pipe diameter can be enlarged and has a wider variable range (the pipe diameter is enlarged by at least 0.6%) by adding the pressure sensitive adhesive layer, and the advantage of the enlarged pipe diameter is better adaptability with the accessory water absorption appliance. In comparative example 2, the strength of the tetrapod-like nano zinc oxide was not decreased, and the corresponding burst pressure was decreased. This is because the tetrapod-like nano zinc oxide has a larger aspect ratio in 4 directions, so that the strength of the obtained pressure sensitive adhesive layer can be higher than that of the conventional nano particles.
In the invention, adhesives such as rosin ester, terpene resin and C5 petroleum resin which are compatible with SIS and SBS rubber phases PI and PB are adopted to endow the pressure sensitive adhesive layer with initial viscosity; the cohesion of the pressure sensitive adhesive layer is improved by adopting coumarone resin and C9 aromatic petroleum resin which are compatible with SIS and SBS plastic phase PS; the terpene phenolic resin is compatible with both the rubber phase and the plastic phase. The adhesive performance of the pressure sensitive adhesive layer can be adjusted through compounding of the adhesives. The selected anti-aging agent has the advantages of light color and difficult oxidation, and the aniline anti-aging agent is easy to oxidize and turns black and is difficult to adopt.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
