Embodiment 1
[0012] The processing method of moisture curing type vacuum embossed artificial leather adopts the following steps
[0013] 1) Artificial leather vacuum embossing: ordinary artificial leather is used as the base embryo and heated to 160-170°C by far-infrared rays, vacuum embossed by a ceramic embossing roller equipped with a vacuum pump, and cooled to room temperature after embossing. The use of far-infrared rays makes the heating process uniform and the energy waste is small, and then passes through the ceramic embossing roller equipped with a vacuum pump. three-dimensional texture.
[0014] 2) Preparation of moisture curing treatment agent: the formula is volume ratio, moisture curing silicone resin LS-3001, 100 parts; toluene TOL, 20 parts; curing agent 7016, 2 parts; defoamer 530, 0.5 parts And leveling agent U-60B, add 0.5 parts into the dye water and stir evenly at high speed. When stirring, use a 32KW high-speed mixer to stir for about one hour, until the dye water and...

[0018] The processing method of moisture curing type vacuum embossed artificial leather adopts the following steps
[0019] 1) Artificial leather vacuum embossing: same as Example 1.
[0020] 2) Preparation of moisture curing treatment agent: the formula is volume ratio, moisture curing silicone resin LS-3001, 100 parts; toluene TOL, 30 parts; curing agent 7016, 5 parts; defoamer 530, 1.5 parts And leveling agent U-60B, 1.5 parts; add dye water and stir at a high speed, use a 32KW high-speed mixer to stir for about one hour, until the dye water and moisture-curing resin are fully stirred and then filtered through a 120-mesh nylon filter to Put it in an iron bucket with a plastic sealing bag and let it stand for 1-2 hours until the slurry completely eliminates the air bubbles.
[0021] 3) Moisture curing treatment on the leather surface: same as in Example 1.
[0022] Performance parameters of the finished product in this embodiment: tensile strength greater than or equal to ...
