Abstract

The invention relates to a water absorption appliance with a variable pipe diameter. The water absorption appliance structurally comprises an inner rubber layer, a pressure-sensitive rubber layer, an outer rubber layer and a spiral reinforcing rib layer from inside to outside in sequence, the pipe diameter of the water absorption appliance can be increased by at least 0.6% through the pressure-sensitive rubber layer; the pressure-sensitive rubber layer is made of a thermoplastic elastomer-based material, and the basic properties of the material are as follows: the tensile strength is more than 12MPa, the elongation is more than 600%, the Mooney viscosity is 15-25, and the peel strength is more than 70N / 25mm; the thickness is 2.5 to 3.5 mm; the material formula of the pressure-sensitive rubber layer comprises the following raw materials in parts by weight: 100 parts of styrene block copolymer, 20 to 80 parts of nanoparticles, 5 to 8 parts of plasticizer, 10 to 30 parts of adhesive and 1 to 3 parts of anti-aging agent. According to the water absorption appliance with the variable pipe diameter, the pipe diameter size has variability, the variable range is wide, higher adaptability with water absorption accessory appliances such as a connector is achieved, and the loading and unloading efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of water-absorbing appliances, in particular to a water-absorbing appliance with variable pipe diameter. Background technique [0002] The water suction device is a device that transports water from the water source to the water pump, including the water suction pipe and the water suction accessories.
