Abstract
The invention discloses a coloring and color-supplementing maintenance agent for leather. The maintenance agent is a water solution, and is prepared from the following components by mass percent: 6-14% of mink oil, 16-28% of fluorocarbon resin, 16-28% of palm wax resin, 7-12% of pigment, 0.1-2.0% of dioctyl sodium sulfosuccinate, 0.5-2.5% of polysiloxane, 0.002-0.006% of a mildew preventive and 6-40% of polyol. The invention also discloses a preparation method of the coloring and color-supplementing maintenance agent for the leather. The maintenance agent has the characteristics of being environmentally-friendly, convenient and fast, strong in bonding force and covering power, and non-caking.
Description
technical field [0001] The invention relates to a leather coloring and color supplement maintenance agent and a preparation method thereof. Background technique [0002] Long-term use of leather products will cause dullness and discoloration. Therefore, for leather products, maintenance agents are usually used for coloring and color replenishment maintenance. The preparation process of the existing leather coloring and color supplement maintenance agent is specifically: acrylic resin, polyurethane resin, adhesive resin, organic solvent, silicone oil, wax paste, leather color paste coating prepared according to a certain proportion, adding aziridine The agent can be sprayed or brushed on the leather after stirring evenly. For the maintenance agent prepared above, there are the following disadvantages: the use of high VOC and restricted substances does not meet the requirements of environmental protection and health; when using, it is necessary to prepare a variety of raw mat...
