Problems solved by technology

However, the natural phospholipid has a darker color, so it is not suitable to be used as a fatliquoring agent for light leather white leather, and its HLB value is low, and its hydrophilicity is poor, which limits its further application.

Abstract

The invention provides a modified phospholipid fat-liquoring agent and a preparation method thereof. The modified phospholipid fat-liquoring agent can improve the water resistance and flexibility of leather through fat liquoring, has a light color and is suitable for the fat liquoring of light color leather. The preparation method of the modified phospholipid fat-liquoring agent comprises the following steps of: (1) adding natural phospholipid, mineral oil and an acylating agent, raising the temperature to be between 90 and 100 DEG C, and reacting for 3 to 5 hours; (2) reducing the temperature to be between 50 and 60 DEG C, adding an antioxidant, stirring for 0.5 to 1 hour, adding a neutralizing agent, regulating the pH value to be between 6 and 8, adding an alcohol solvent, a modified surfactant and a preservative in turn, keeping the temperature of between 50 and 60 DEG C, and stirring for 1 to 1.5 hours; and (3) slowly adding a certain amount of distilled water to ensure that oil content is between 85 and 90 percent, and fully stirring for 2 to 5 hours to obtain the modified phospholipid fat-liquoring agent. The method is relatively simple, low in equipment requirement and short in production period.

Description

technical field [0001] The invention relates to a fatliquoring agent and a preparation method thereof, more specifically, the present invention relates to a modified phospholipid fatliquoring agent and a preparation method thereof. Background technique [0002] Fatliquor is one of the important chemical materials in leather processing. It lubricates the leather fibers, prevents the leather from becoming stiff and cracking, and makes the leather have corresponding toughness and softness, and maintains its strength. At the same time, it plays a certain filling role, making the leather plump and elastic. It can be called a fatliquoring agent. It is one of the important factors affecting the quality and performance of leather. In the study of fatliquoring agents, fatty acid higher alcohol esters, natural phospholipids, hoof oil, lanolin, fatty alcohol phosphates, and synthetic macromolecular polyphosphates all have good filling properties. Among them, phospholipid fatliquor ha...
