Problems solved by technology

The service life of the current washing machine drain pipe is not long, and due to poor dynamic performance, the washing machine drain pipe produces large vibration noise and is easy to deform, which affects the washing effect and service life of the entire drum washing machine
[0003] The reason for the above problems is that the drain pipe of the drum washing machine requires excellent low deformation, so as to ensure its excellent sealing performance, while the drain pipe used in the drum washing machine in the prior art has poor deformation resistance

Embodiment 1

[0052] First, 160 parts of EPDM rubber, 130 parts of carbon black, 40 parts of paraffin oil, 5 parts of indirect method zinc oxide, 1.5 parts of anti-aging agent, 3 parts of lubricant, 2 parts of auxiliary crosslinking agent and 3 parts of The vulcanizing agent is placed in an internal mixer for mixing to obtain synthetic rubber.

[0053] Next, the above-mentioned synthetic rubber is extruded and molded after being uniformly heated by an open mill, and then the extruded rubber strip is injected into the mold in the vulcanization equipment, and the pressure is 190Kgf / cm 2 , the temperature was raised to 175°C, and the vulcanization treatment was carried out for 360 seconds.

[0054] Finally, the drain pipe obtained after the vulcanization treatment is trimmed, inspected, packaged and put into storage to obtain the drain pipe.

Embodiment 2

[0056] The raw material composition of synthetic rubber is: 175 parts of EPDM rubber, 130 parts of carbon black, 40 parts of paraffin oil, 5 parts of indirect zinc oxide, 1.5 parts of anti-aging agent, 3 parts of lubricant, 2 parts of auxiliary crosslinking agent and 3 parts of Part vulcanizing agent, except that, other conditions are all with embodiment 1.

Embodiment 3

[0058] The raw material composition of synthetic rubber is: 190 parts of EPDM rubber, 130 parts of carbon black, 40 parts of paraffin oil, 5 parts of indirect zinc oxide, 1.5 parts of anti-aging agent, 3 parts of lubricant, 2 parts of auxiliary crosslinking agent and 3 parts of Part vulcanizing agent, except that, other conditions are all with embodiment 1.

Abstract

The invention discloses a drainpipe for drum type washing machine and a preparation method thereof. The drainpipe comprises the following components in parts by weight: 160 to 190 parts of ethylene propylene diene monomer, 120 to 140 parts of carbon black, 30 to 50 parts of paraffin oil, 4 to 6 parts of zinc oxide, 1 to 2 parts of antioxidant, 2 to 4 parts of lubricant, 1 to 4 parts of auxiliary crosslinking agent, and 2 to 4 parts of vulcanizing agent. By optimizing the addition amount of ethylene propylene diene monomer, carbon black, paraffin oil, zinc oxide, antioxidant, lubricant, auxiliary crosslinking agent, and vulcanizing agent, the drainpipe has an excellent anti-deformation property, and also has a long service life and improved damping and sealing effects.

Description

technical field [0001] The invention relates to the technical field of drum washing machines, in particular to a drainpipe for drum washing machines and a preparation method thereof. Background technique [0002] Throughout the product development trend, with the gradual improvement of people's living standards, people have higher and higher requirements for the vibration and sealing of washing machines. As an important component of the drainage system of the drum washing machine, the drain pipe on the drum washing machine plays the role of shock absorption, sealing and ventilation for the drum washing machine, and its performance directly affects the service life of the drain pipe. The service life of the current washing machine drain pipe is not long, and due to poor dynamic performance, the washing machine drain pipe produces relatively large vibration noise and is easily deformed, which affects the washing effect and service life of the entire drum washing machine.
