White anti-yellowing cow split leather processing formula, processing technology and equipment

[0043] Example 1

[0044] like figure 1 As shown, a white-resistant yellow cattle lattice leather processing formula is composed of the ingredients of the following weight parts: 12-20 high-viscous polyurethane resins, 黄 黄 超 软 树 树2.3-5.8 copies of ethylene glycol, 0.1-1.5 salicylic acid, 1-5 pH regulators, 0.01-0.05 zinc oxide, 0.02-0.06 white carbon black, surfactant 0-10 0.8-3.2 parts of 3-mercapto propionic acid, 30-70 water, 0.05-0.08 thickeners.

[0045] A white-resistant yellowing cattle two-layer leather processing processes, the specific steps are as follows:

[0046] Step 1, high-viscosive polyurethane resin, 黄 黄 超 软 合 树, 9-12 parts, salicylic acid, pH regulator, zinc oxide, white carbon black, surfactant, 3-mercaptoacid and water The reaction kettle temperature was controlled at 35-45 ° C, and the stirring speed was controlled at 1600-2200 r / min, and the mixture was stirred for 22-35 min.

[0047] Step 2, adding the thickener to the mixture to continue stirring, so that
