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:
The invention belongs to main is the cleaning composition field of base-material with the tensio-active agent, be mainly used in pigskin, ox-hide, the tanned blue skin cleaning and degreasing of sheepskin, relate to the mixture of Soxylat A 25-7, poly-third Vinyl Ether, alkylolamide class nonionogenic tenside, solvent, solubility promoter, acid lipase enzyme and defoamer combination.
Background technology:
It is extremely important to processing high-quality leather to remove natural fat from animal fur, particularly animal fur contains under the situation of very high natural fat content, the existence of natural fat can influence the infiltration and the effect of chemical materials, these natural fats can be gone mouldy by degradation by bacteria in leather use and storage process, the high-molecular weight saturated fatty acid can be seeped into leather surface and form oil mark, influences the outward appearance and the physicals of leather.According to prior art, the method that is used for the animal fur degreasing has solvent degreasing and emulsion degreasion, and by main degreasing process, abdomen neck position fibre gap cavity grease is easy to remove in the animal fur course of processing.In the operation afterwards, by alkali swelling, deliming, enzyme bating and pickled chemical action, the fiber at stern back is fully disperseed, behind secondary degreasing, can remove the natural fat of animal fur 70%～80%, make animal fur natural fat content be reduced to 3%～5% from 10%～20%.Animal fur becomes blue skin by chrome tanning process, and this 3%～5% natural fat still influences the following process process of leather.Blue skin leather fiber is crosslinked fixing by tanning agent, wants to make that natural fat is reduced to below 1% in the blue skin, and existing skimmed prod and degreasing method are difficult to finish.
Summary of the invention:
At the deficiency that prior art exists, the present invention becomes water-fast organic solvent and water miscible tensio-active agent compatible combination the liquid of limpid homogeneous transparent.Realize that water-fast organic solvent and water miscible tensio-active agent form superfine microemulsion in liquid, outward appearance presents transparent liquid, is not the oyster white that traditional water fat liquor presents, and improves the degreasing efficient and the visual appearance of product.
In the technical scheme of the present invention, introduced new component acid lipase enzyme, this lipase can be with the degraded of the natural fat in the blue skin, and the easier dissolving of fat acid decomposition product, emulsification remove.Component and proportioning (w%) that this limpid homogeneous transparent contains the microemulsion grease-removing agent of acid lipase enzyme are
Tensio-active agent 20～60
Solvent 10～40
Solubility promoter 0～5
Acid lipase enzyme 0～10
Defoamer 0～2
Water 40～60
Above-mentioned tensio-active agent is one or both of fatty alcohol-polyoxyethylene ether, fatty alcohol polyoxypropylene ether, alkylolamide class nonionogenic tenside; Solvent is one or both in the solvent oil, trieline, zellon, solvent kerosene of toluene, dimethylbenzene, turps, C8～C12; Solubility promoter is one or both in ethanol, n-propyl alcohol, Virahol, the butyl glycol ether.Wherein tensio-active agent preferably uses HLB value＞8, the nonionogenic tenside of especially preferred H LB value＞12, the alcohol of fatty alcohol-polyoxyethylene ether, fatty alcohol polyoxypropylene ether is 8～12 the isomery Fatty Alcohol(C12-C14 and C12-C18) that has side chain, oxyethyl group (propoxy-) is 8～10, this isomery alcohol ether nonionogenic tenside surfactivity is strong, wetting, emulsification, dispersion, detersive power excellence.Alkylolamide class nonionogenic tenside is the alkylolamide of the natural alkyd 1:2 type of 12～18 carbon.Lipase is acid lipase enzyme, applicable pH value 2.0～7.0,30 ℃～50 ℃ of temperature.Defoamer is the block polymerization siloxanes, and it is strong to press down bubble property, and consumption is few, does not influence the various technical parameters of system.
Through a large amount of tests, screening formulation is as follows:
Tensio-active agent 45～55
Solvent 15～25
Solubility promoter 2～4
Acid lipase enzyme 5～8
Defoamer 0～1
Water 30～50
The as clear as crystal microemulsion Applicable temperature scope of high efficiency low-foaming blue leather degreaser of the present invention is wide, can forever place not stratified in stable condition.This microemulsion grease-removing agent has the advantage of solvent degreasing and emulsion degreasing concurrently, and existing organic solvent dissolves cleansing power to grease, and the cleaning characteristics of aqueous tenside is arranged again.Wherein lipase can form steatolysis glycerine, lipid acid, monoglyceride, diglyceride, has the certain surface activity and more helps greasy cleaning removal.Product of the present invention has that smell is little, safety and stability, nonflammable, cost performance is high, carry out product degreasing efficiency test with the blue skin of sheep clothing leather, its degreasing efficient is under the identical situation of degreasing cost, be better than traditional neat solvent and aqueous degreasing agent, can make that natural fat is reduced to below 1% in the blue skin.
