Abstract
The invention discloses a comb-shaped amphiphilic modified styrene-maleic anhydride (SMA) tanning agent and a preparation method thereof. SMA is subjected to esterification modification by using fatty alcohol and polyethylene glycol monomethyl ether to form the comb-shaped amphiphilic modified SMA tanning agent; and a lipophilic long-chain alkyl group, a hydrophilic ethyoxyl group and a hydrophilic carboxyl group are synchronously introduced into a molecular structure of the tanning agent. Original performance advantages of an SMA tanning agent are kept, and the tanning agent also overcomes the disadvantages of hard handfeel, easiness in color loss, low leveling property, no electrolyte resistance and the like when the using amount of the SMA tanning agent is large in retanning and fatliquoring of tanning. Therefore, the tanning agent is a functional material which integrates retanning, filling and fatliquoring into a whole, can endow finished leather with high elasticity, plump performance and fatliquoring performance, and has broader application prospect in the tanning industry.
Description
Technical field
The present invention relates to the leather chemicals production field, be specifically related to SMA tanning agent of a kind of comb shape amphiphilic modification and preparation method thereof.
Background technology
1945, Alfey and Lavin started the beginning of styrene-maleic anhydride copolymer (SMA) research.Afterwards, Mayo has carried out systematic research to the phenylethylene-maleic anhydride copolymerization system, thinks that this system copolymerization product is a kind of typical alternating copolymer.So far, the preparation of SMA and the research of application more and more are subject to people's attention.
At home, Zhang Juxian etc. are applied to process hides the earliest with the sodium salt (SMA tanning agent or KS-1 synthetic tanning agent) of SMA, careful through its tanned crust leather grain, pore is clear, and the leather body is plentiful, the yield of leather height, have and significantly brighten thickening characteristics, be particularly suitable for producing white and remove from office and the light color leather, chromium is also had absorption, fixed action, can reduce the chromium content in the waste liquid, reduce environmental pollution.Its related products also has the DLT-14 synthetic tanning agent, PR-1 retanning agent product of Renektan QS, Dandong light industry research institute development of French Kuhlman Corp. (US) 2565 West Maple Road, Troy, Michigan 48084, United States of etc.So the polymkeric substance of SMA based structures has comparatively widely at leather industry as retanning agent to be used always.
But the sodium salt of SMA early also has fatal shortcoming as retanning agent.Material styrene is the stronger monomer of rigidity, and its multipolymer second-order transition temperature is higher, can cause leather hand feeling harder after the retanning; Contain a large amount of carboxyls in this SMA tanning agent molecule, the leather fiber negatively charged ion is electrically strengthened, can influence the dyeing of later stage leather, easily produce the phenomenon of losing colour, make dyeing inhomogeneous, not bright-coloured.
In recent years, many process hides workers concentrated on the study on the modification work to the SMA tanning agent on the anhydride group on the molecular backbone chain.Because the ring molecule of maleic anhydride contains carbon-carbon double bond and carbonyl conjugated structure, reactive behavior is very high, can carry out addition reaction, Diels-Alder reaction, esterification, amidate action etc.Therefore, utilize the principle that the unitary anhydride group of maleic anhydride and chemical compound lot can carry out graft modification among the SMA, can form many SMA derivatives,, mainly contain following research about the SMA derivative and in the research aspect the leather tanning with value:
(preparation and the application performance thereof of SMA aliphatic alcohol monoesters sodium salt such as Li Xiaohua, Chinese leather .2009,3(38): 40 ~ 43.) SMA is carried out esterification modification, prepared the high fatty alcohol monoesters of SMA with Fatty Alcohol(C12-C14 and C12-C18) (lauryl alcohol, tetradecyl alcohol, hexadecanol or stearyl alcohol).This product back finished leather better softness of tanning, this method have been improved the harder shortcoming of leather hand feeling after the SMA retanning, but the wetting ability of this product is not strong, and emulsion dispersion property is not good, and emulsification is difficulty comparatively, has influenced retanning stuffing effect.
Zhang Fulian, (synthesizing of toxilic acid castor-oil plant alcohol ester-styrol copolymer such as Zhang Xilan, print during chemical industry. 2003,6(17): be that raw material is by the synthetic toxilic acid castor-oil plant alcohol of esterification monoesters with ricinoleic acid and maleic anhydride earlier 28 ~ 30.), carry out free-radical polymerized with vinylbenzene again, prepare a kind of tanning agent that has retanning, filling, stuffing and help the effect of dying after the modification, this product is also given characteristics such as finished leather softness, plentiful, level dyeing, waterproof except that the advantage that keeps the SMA tanning agent.
Summary of the invention
SMA tanning agent of and a kind of modification that provide not enough in performance aspect leather retanning, the stuffing at existing research product and preparation method thereof is provided.Main thought is: adopt Fatty Alcohol(C12-C14 and C12-C18) and poly glycol monomethyl ether that SMA is carried out common esterification modification, on the SMA molecular backbone chain after the modification, introduce chain alkyl, can effectively reduce the frictional coefficient between the collegen filament after the retanning, leather fiber is had lubricated submissive effect, finally play the stuffing effect; In addition, on this molecular backbone chain, introduce hydrophilic oxyethyl group again, can effectively improve water-soluble, the acidproof and electrolyte-resistant performance of SMA tanning agent after the modification.SMA tanning agent molecular chain after its modification is comb shaped structure, also has hydrophilic and two kinds of chemical groups of oleophylic on the side chain simultaneously, makes this polymkeric substance have amphipathic constitutional features, also belongs to a kind of comb polymer molecule tensio-active agent.
In order to achieve the above object, the technical solution used in the present invention is:
