Embodiment Construction

[0010] 1. Weighing:

[0011] Weigh 50-65kg of polyether, 30-50kg of toluene, 1-10kg of methane, 0.1-0.5kg of amine, 0.15-0.5kg of stannous, 1-3kg of silicone oil and 1-20kg of recrystallized powder.

[0012] Two, prepare the first mixture:

[0013] Put polyether and recrystallized powder into the first stirrer, stir and preheat to 22±5°C to form the first mixture.

[0014] Three, prepare the second mixture:

[0015] Put toluene, methane, amine, stannous and silicone oil into the second stirrer, stir and preheat to 22±5°C to form the second mixture.

[0016] 4. Production:

[0017] The first mixed material and the second mixed material are mixed, blended in a stirrer with a rotation speed of 4000-6000 rpm, pumped into an oven with a temperature of 10-35°C, and continuously foamed within 120-150 seconds.

[0018] 5. After the material is discharged, apply external force on the upper and lower sides of the sponge to release the gas in the sponge, and then cool and shape it na...

Abstract

The invention relates to a production process for slow-resilience sponge, and relates to the technical field of sponge foaming process. According to the present invention, polyether and barite powder are stirred to form a first mixed material; toluene, methane, amine, stannous and silicone oil are stirred to form a second mixed material; the first mixed material is mixed with the second mixed material; the resulting mixture is subjected to blending in a mixer having a rotation speed of 4000-6000 rotation per minute; the blended material is pumped to an oven having a temperature of 10-35 DEG C to carry out foaming within 120-150 seconds; after the material is discharged, external forces are respectively applied on the upper surface and the lower surface of the sponge to discharge the gas inside the sponge; then the treatments of natural cooling and forming are adopted to prepare the slow-resilience sponge. According to the present invention, the slow resilience of the product can be realized so as to adapt to special occasions.

Description

technical field [0001] The invention relates to the technical field of sponge foaming technology. Background technique [0002] With the expansion of the application field of sponge products, in some high-end shoes, sponges with slow rebound are required. And the sponge that common processing technology produces can't adapt to market demand. Contents of the invention [0003] The object of the present invention is to propose a production process of a sponge with slow resilience properties. [0004] The present invention comprises the following steps: [0005] 1) Put polyether and recrystallized powder into the first mixer, stir and preheat to 22±5°C to form the first mixture; [0006] 2) Put toluene, methane, amine, stannous and silicone oil into the second agitator, stir and preheat to 22±5°C to form the second mixture; [0007] 3) Mix the first mixture and the second mixture, blend in a stirrer with a rotating speed of 4000-6000 rpm, pump them into an oven at a tempe...
