Problems solved by technology

[0002] The main shortcoming of existing rubber foam sole, plate, sheet production method has: (1) main rubber material only adds ethylene and polyethylene with natural rubber or butadiene rubber, in the substitution of raw material use not flexible enough, when raw material price rises When there is a shortage of raw materials, it will cause pressure on costs; when there is a shortage of raw materials, it will cause production to stop.
(2) The foam sole made of natural rubber has the advantages of light weight and softness, but its wear resistance and tear resistance are poor. Generally, the value that can be achieved is sub-clone 2 pounds 2000 rpm below 1.0 (the lower the wear value, the wear resistance the better)
(3) The rubber foam sole made of natural rubber is easy to make mistakes because of the two feeding procedures of porous material and wear-resistant material, and then filling the mold with a certain ratio of the two materials into the mold for vulcanization and hot pressing. And the process is more cumbersome
(4) The rubber foam sole made of butadiene rubber (artificial rubber) plus ethylene and polyethylene can fill the deficiency of natural rubber in physical properties, but it is not yet the best. Butadiene rubber plus ethylene and polyethylene The wear resistance of the foamed sole is better than that of natural rubber, but there is still the problem of raw material substitution. In addition, because of the plasticization process, the mold must be cooled from 150 degrees to 40 degrees by water, and then the filler is placed in the vulcanizer and the temperature is raised to 150-degree plasticization, such a continuous cycle, the process is complicated and inefficient

Embodiment 1

[0016] Embodiment 1: processing of rubber foam bottom, plate and sheet

[0017] The concrete manufacturing method of rubber foam outsole, plate, sheet of the present invention is:

[0018] 1. Take 100 kg of wind rubber and put it into a closed rubber mixer for 3 minutes of mastication. The working temperature of the mixer is 120-130 degrees (the temperature is low when the machine is started first, and it needs to be kept at 120-130 degrees during the operation cycle. ), the gravity hammer pressure is 8 kilograms, then take it out for later use.

[0019] 2. Take 12 kg of wind rubber after mastication, 60 kg of EVA regenerated sheet (ethylene vinyl acetate copolymer), 20 kg of butadiene rubber, and 1 kg of silicon dioxide and put them into the closed mixer in sequence (the order is not limited) ), turn on the machine, press the gravity hammer (pressure 48KGS) for 6 minutes and then raise the gravity hammer for ventilation. The process of raising the hammer for ventilation is a...

Embodiment 2

[0026] Embodiment 2: rubber foam bottom, plate, sheet and the method for printing and dyeing cloth molding

[0027] The specific manufacturing method of rubber foam bottom, plate, sheet and cloth-added molding of the present invention is:

[0028] 1. Take 100 kg of glue and put it into a closed rubber mixer for mastication for 6 minutes. The working temperature of the mixer is 50°C, and the pressure of the gravity hammer is 8 kg, and then take it out for use.

[0029] 2. Put 35 kg of latex glue, 30 kg of EVA regenerated sheet, 5 kg of isoprene (IR), and 2 kg of silicon dioxide into the closed mixer to start the machine and press the gravity hammer (pressure 6KGS) After mixing for 6 minutes, raise the gravity hammer to ventilate. The process of raising the hammer for ventilation is about 30 seconds, and then press the hammer for about 4 minutes. Raise the gravity hammer to open the machine mold door and put in 10 kg of light calcium carbonate (CC powder), 0.6 1 kg of anti-agin...
