Abstract
The invention relates to the fields of leather processing and materials and relates to an environment-friendly surface active agent for tanning. The surface active agent comprises the active constituents of sucrose fatty ester and alkyl glycoside, wherein the mass ratio of sucrose fatty ester to all C8-C14 fatty alcohol in alkyl glycoside is 1 : (0.25-0.4). The surface active agent prepared by compounding sucrose fatty ester and alkyl glycoside can be used for conditioning, degreasing and other procedures for tanning and is environmental-friendly, easy to degrade and simple to prepare.
Description
Technical field
The present invention relates to leather processing field and Material Field, be specially a kind of environment-friendly type process hides tensio-active agent and preparation method thereof.
Background technology
Degreasing is one of requisite operation in the process hides processing, and the degreasing Main Function is that the grease in epidermis face and the sebiferous gland is removed.The quality of degreasing effect is directly connected to the effect of tanning, dyeing, stuffing etc.; The effect of degreasing is also very large to the leather goods quality influence, if the effect of degreasing is bad, can cause that the finished leather feel is stiff, the surface oil soapy feeling is strong, coating easily comes off the defectives such as slurry.
The tensio-active agent that process hides is used has comprised aniorfic surfactant, cationic surfactant, nonionic surface active agent and amphoteric surfactant.
The tensio-active agent that process hides is used, the body lotion environment of use are comparatively complicated, therefore require acid and alkali-resistance, anti-hard water and electrolyte-resistant.The tensio-active agent kind that meets these requirements is few, quantity is single, and the tensio-active agent that some use for a long time, such as sodium laurylsulfonate, NEPs(nonylphenol polyoxyethylene ether sulfate) etc. because reasons such as environmental pollutions, difficult degradation, use day by day restrictedly, use perhaps is under an embargo.
Nonionic surface active agent is suitable for PH wide ranges etc. because degreasing effect is outstanding, biodegradable degree high, in process hides with development in the tensio-active agent rapidly.
Gentle, efficient, eco-friendly direction is the trend of leather degreasing tensio-active agent development.But the at present surfactant product of efficient, high biochemical degradation degree exploitation dynamics is not enough, therefore needs to optimize compounded technology, and prior art is improved, and obtains the process hides tensio-active agent of the high biochemical degradation degree of environment-friendly type.
Summary of the invention
The object of the present invention is to provide process hides tensio-active agent and the preparation method thereof of the high biochemical degradation degree of a kind of environment-friendly type.
The process hides tensio-active agent of the high biochemical degradation degree of a kind of environment-friendly type, its active ingredient comprises sucrose fatty ester, alkyl glycoside; Described process hides is during with viscosity number 〉=150mPas(25 ℃ of tensio-active agent) (being generally 150～3000).Wherein the mass ratio of C8 in sucrose fatty ester and the alkyl glycoside～C14 Fatty Alcohol(C12-C14 and C12-C18) total amount is 1:0.5～0.8, preferred 1:0.55～0.7, more preferably 1:0.6～0.65.
Preferably, alkyl glycoside is the mixture of C8, C10, C12 and C14 alcohol, and wherein, C8, C10, C12 and C14 alcohol mass ratio are 1:0.5～2:1～3:0.2～1; Be preferably 1:1～1.5:1.2～2:0.4～0.75;
Preparation method of the present invention is, with sucrose fatty ester and alkyl glycoside mixing in proportion, adds 0.1wt%～2wt% salts solution and alkylolamide adjusting viscosity value.The addition of salts solution is for mixing the 4wt%～6wt% of rear surface promoting agent gross weight, and the addition of alkylolamide is for mixing the 1.6wt%～2.5wt% of rear surface promoting agent gross weight.
By method of the present invention, composite sucrose fatty ester and alkylglycoside and the tensio-active agent that makes can be used for the operations such as returning of process hides is wet, degreasing.This tensio-active agent hydrophilic-lipophilic balance is effective, uses in the process hides degreasing process, and degreasing is thorough; And this tensio-active agent is environmentally friendly, easily degraded, and preparation is simple.
