Abstract

The invention relates to a degreaser used for degreasing blue leather. The degreaser is a washing composite mainly using surfactant as base material and is clear and transparent microemulsion. The formula of the degreaser comprises the following components by weight percent: 20-60% of surfactant (one or two of non-ionic surfactants such as fatty alcohol polyoxyethylene ether, fatty alcohol polyoxypropylene ether and alkanolamide, 10-40% of solvent (one or two of toluene, xylene, turpentine, C8-C12 of solvent oil, trichloroethylene, tetrachloroethylene and solvent kerosene), 0-5% of cosolvent ( one or two of ethanol, n-propanol, isopropanol and ethylene glycol monobutyl ether, 0-10% of acidic lipase, 0-2% of defoaming agent and 40-60% of water. The application temperature of the microemulsion degreaser is wide, and can be stored for long time without layering and have stable state; and the degreaser has the advantages of solvent degreasing and emulsion degreasing, the fat dissolving and cleaning functions of organic solvents and the cleaning characteristics of water-based surfactants. Therefore, the natural fat in blue leather can be reduced to less than 1%.

Description

Technical field: [0001] The invention belongs to the field of cleaning compositions mainly using surfactants as base materials, and is mainly used for cleaning and degreasing blue leather after tanning of pigskin, cowhide and sheepskin, and relates to polyoxyethylene ether, polypropylene ether and alkanolamide nonionic A mixture of surfactants, solvents, co-solvents, acid lipase and antifoam combinations. Background technique: [0002] The removal of natural fats from animal hides is very important for the processing of high-quality leather, especially in the case of animal hides with high natural fat content, the presence of natural fats will affect the penetration and action of chemical materials, these natural fats are used and stored in the leather The medium will be degraded and mildewed by bacteria, and the saturated fatty acid with high molecular weight will seep into the leather surface to form oil spots, which will affect the appearance and physical properties of th...
