Abstract

The invention provides a compound complex type greasing agent and a preparation method thereof. The preparation method comprises the following steps: (1) adding 200-300 parts of triolein and 200-250 parts of isotridecanol polyoxyethylene ether into a reaction kettle, rising temperature up to 80 DEG C, sampling and detecting moisture, after moisture is evaporated, adding 80-100 parts of maleic anhydride and 5 parts of antioxidant BHT while stirring, rising temperature up to 180-220 DEG C, reacting for 1 hour; (2) reducing temperature down to 80 DEG C, adding 30-60 parts of emulsifier, slowly adding 150-200 parts of mass percentage concentration 30% sodium hydroxide solution; (3) adding 300-350 parts of mass percentage concentration 33% sulfonating agent solution, thermal reacting for 3-4 hours at 90-95 DEG C; (4) reducing temperature down to about 60 DEG C, adding 500-700 parts of triolein, 500-900 parts of 75% sulfonated oil SS, 50-70 parts of cosolvent, and 10 parts of preservative cason, then adding water so as to regulate solid content to be 60% to obtain reddish brown transparent liquid-the compound complex type greasing agent.

Description

technical field [0001] The invention relates to a synthetic composite fatliquoring agent and a preparation method thereof, belonging to the technical field of leather chemical industry. Background technique [0002] Fatliquoring is the most critical process in tanning production. In order to increase the storage time, the leather must be degreased. In the fatliquoring process, the leather is properly fatliu It restores the original softness and elasticity, prevents the leather from becoming stiff and cracking, and endows the leather with certain usability. Through fatliquoring, the tensile strength, toughness, elongation, leather yield, etc. of the leather are improved, and at the same time, the water resistance is significantly improved, and the leather is also endowed with a good feel. In addition, in addition to lubricating the fiber to help soften the leather, the partially bonded fatliquoring material also has multifunctional effects such as supplementary tanning, fill...
