[0059] As preferably, the preparation method of described self-adhesive colloid comprises the steps:
[0060] Q1. Weigh each component raw material according to the mass percentage, and set aside;
[0061] Q2. Add water-based natural rubber latex and ethylene-vinyl acetate copolymer emulsion into a stirring container, and stir evenly for 15 minutes to 20 minutes at a rate of 25 rpm to 30 rpm to obtain a mixed glue;
[0062] Q3. Heat the mixed glue solution to 40°C to 42°C, then add defoamer and preservative, and stir evenly for 5 minutes to 8 minutes;
[0063] Q4. Pour it into a storage tank at 35 degrees Celsius to 38 degrees Celsius, and cool it naturally to get a self-adhesive colloid.
[0064]The sewing process of the upper and the sole of a safety shoe provided by the present invention can improve the comfort by placing the inner lining inside the upper, and punching holes after sequentially bonding and positioning can ensure positional stability and avoid Offset and di...

[0066] A safety shoe upper and sole sewing process, the safety shoe upper and sole sewing process comprises the following steps:
[0067] P1. Shear forming: cut the upper and sole, and reserve 4 mm width at the edge;
[0068] P2. Lining fixation: Apply self-adhesive colloid on the surface of the inner lining, stick it to the inside of the upper, and cut and trim along the edge of the upper;
[0069] P3. Edge trimming: Thinning the back and front of the upper and sole edge along a 45-degree angle to form a triangular edge with a width of 3 mm to 4 mm;
[0070] P4. One-time adhesion: apply self-adhesive colloid on the triangular edge of the upper and sole, and then butt and press;
[0071] P5. Punching: On the upper and sole after the first adhesion, in the adhesion position, use a punch to punch holes with a distance of 3 mm to 4 mm, and continue to operate along the circumferential direction;
[0072] P6. Suture: Select the appropriate thread, and then pass through the punch...
