Definitions
- New leather treatment agents processes for their production and their use in the production of low-fogging leather
- the invention relates to new leather treatment agents for the production of leather with low levels of volatile components, in particular for high-quality car upholstery leather, a process for producing these agents and their use in the production of low-fogging leather.
- Car upholstery leather has to meet certain criteria. What is important on the one hand is the softness, on the other hand the authenticity to light and heat influences and finally the so-called fogging behavior.
- DIN 75201 defines fogging as the condensation of evaporated volatile components from the vehicle interior on the glass panes, especially on the windshield. The same standard also describes a gravimetric and a reflectometric method for characterizing the fogging behavior of leather.
- EP 49S 634 A2 recommends special polymers for the production of low-fogging leather, the aqueous dispersions being essentially free of organic solvents and containing an amphiphilic copolymer which consists of a predominant proportion of at least one hydrophobic monomer and a minor proportion consists of at least one hydrophilic monomer. Treatment of the leather with these dispersions leads to good results in a gravimetric test according to DIN 75201. Reflectometric studies were not disclosed.
- amphiphilic copolymers are preferably prepared in an aqueous emulsion polymerization.
- this naturally leads to problems in the copolymerization behavior, which in extreme cases can lead to the monomers each forming homopolymers in an undesirable manner.
- Another consequence of the inherently unfavorable solution conditions is a complex post-processing to destroy residual monomers.
- it is also necessary to use a sufficient amount of an emulsion. gators (lauryl sulfate was used in the examples above), which can lead to wastewater problems in leather processing.
- EP 466 392 B1 describes a process for the preparation of polymers which contain both pendant hydrophobic groups and pendant alkoxylated groups and which are obtained by derivatizing polymers after the actual polymerization process using customary processes.
- polymers are preferably produced from simple monomers such as acrylamide and / or acrylic acid by conventional polymerization and then derivatized with a mixture of primary or secondary hydrophobic amines and primary or secondary alkoxylated amines.
- Such derivatized polymers are used as thickeners and soil release agents.
- the object of the invention was therefore to provide new, easy-to-produce, essentially self-emulsifying agents with little residual monomers for leather treatment, a process for their manufacture and a process for leather manufacture using these agents, in which leather has very low contents evaporating volatile constituents (low-fogging leather), determined both by gravimetric and by reflectometric measurement methods, the other important leather properties such as softness, fastness to light and heat influences etc. not being impaired.
- the invention relates to new leather treatment agents, in particular for car upholstery leather, available from
- R a C 2 -C 30 alkyl or alkenyl radical and R 2 H, a C r C 4 alkyl or mean, optionally C
- the invention is also a process for the preparation of the leather treatment agent, which is characterized in that the monomers al), a2) and a3) are polymerized by free radicals, preferably in solution, then the polymer obtained either immediately or after prior removal of the solvent with the amines of the Formula R, -NH-R 2 , wherein R, and R 2 have the meaning given in claim 1, wherein at least some of the acid groups present in the polymer are converted into the corresponding amide groups, followed by dilute base, optionally with the addition of Water, the remaining carboxyl groups are partially or completely neutralized.
- the polymers are prepared by radical polymerization of, based on the total batch, 70-100% by weight, preferably more than 80% by weight, of acrylic acid and / or methacrylic acid and / or their acid chlorides and / or anhydrides.
- acrylic acid and / or methacrylic acid and / or their acid chlorides and / or anhydrides are copolymerized.
- 0 to 30% by weight of further copolymerizable water-soluble monomers are copolymerized.
- Suitable monomers from this group are (meth) acrylamide, (meth) allyl alcohol, hydroxyethyl (meth) acrylate, hydroxypropyl (meth) acrylate, hydroxyalkyl polyethylene oxy (meth) acrylate, alkyloxypolyethyleneoxy (meth) acrylate, polyethylene glycol monoallyl ether, N-vinylpyrrolidone or N -Vinylimidazole.
- monomers containing acid groups such as maleic acid, itaconic acid, vinylsulfonic acid, methallylsulfonic acid, 2-acrylamido-2-methylpropylsulfonic acid, 4-vinylphenylsulfonic acid, vinylphosphonic acid and their water-soluble esters, anhydrides, alkali metal, alkaline earth metal and / or ammonium salts can also be used.
- acid groups such as maleic acid, itaconic acid, vinylsulfonic acid, methallylsulfonic acid, 2-acrylamido-2-methylpropylsulfonic acid, 4-vinylphenylsulfonic acid, vinylphosphonic acid and their water-soluble esters, anhydrides, alkali metal, alkaline earth metal and / or ammonium salts can also be used.
- basic monomers such as, for example, dimethyla inoalkyl (meth) acrylate and / or dimethylaminoalkyl (meth) acrylamide and / or their quaternized forms in the polymerization.
- the polymers from these monomers naturally have a very hydrophilic character. It can therefore make sense to influence the hydrophilicity by using 0 to 20% by weight of one or more monomers from the group of hydrophobic monomers.
- This group includes, for example, C1 -C30 alkyl (meth) acrylates, vinyl esters of Cj-
- C30 carboxylic acids vinyl ethers of C1-C30 alcohols or ethylenically unsaturated aromatic monomers, such as styrene.
- the polymerization itself can be carried out by the process of bulk, solution, suspension or emulsion polymerization.
- the process of solution polymerization is preferred, the solvent having to meet the condition that it can dissolve all the monomers used. Accordingly, water, C [-C 4 - alcohols and their ethylene oxide adducts, glycols and ketones such as acetone or methyl ethyl ketone are suitable, with higher-boiling organic solvents being preferred in the end product because of their more favorable fogging behavior.
- the use of butyl glycol and butyl diglycol as a solvent in the polymerization is particularly preferred.
- the polymerization can be carried out batchwise or continuously, for example in a cascade of reaction vessels. If the reaction is carried out batchwise, a feed process is preferred in which monomers and initiator are metered into the initial charge over a period of several hours at a constant temperature. Adiabatic driving is also possible, however which the monomers are introduced in whole or in part and the resulting heat of polymerization leads to an increase in temperature and to an accelerated reaction of the monomers of the batch.
- the initiation of the radical polymerization is triggered by conventional starters, for example by the thermally or photochemically induced decomposition of radical-forming peroxide and / or azo compounds and / or by suitable redox systems, the selection of the suitable system being based on the intended reaction temperature and the rate of conversion.
- starters for example by the thermally or photochemically induced decomposition of radical-forming peroxide and / or azo compounds and / or by suitable redox systems, the selection of the suitable system being based on the intended reaction temperature and the rate of conversion.
- the adiabatic polymerization of the monomers it can make sense to use several starters, for example with different decomposition temperatures. As a rule, those systems are preferred which have sufficient solubility in the reaction medium.
- the amounts of initiator are preferably in the range from 0.01 to 1% by weight, based on the sum of the monomers.
- the molecular weight of the polymers is regulated via the reaction conditions and / or by using regulators, such as mercaptans.
- the amount of regulator is preferably in the range from 0 to 5% by weight, based on the sum of the monomers.
- the number average molecular weights of the polymers obtained are between 1000 and 100,000 g / mol.
- Reaction temperatures in the range from 20 to 200 ° C. are preferred, and the polymerization can also be carried out under pressure if necessary.
- the polymerization time is advantageously 0.5 to 8 hours.
- step B either the polymer-analogous reaction of the polymer in step B) is continued immediately or else the solvent is first separated from the polymer, for example by distillation.
- the latter is in aqueous polymerization Medium necessary to achieve sufficient conversion in the subsequent reaction of the polymer.
- Step B implementation with fatty amines
- part of the acid groups present in the polymer is reacted with fatty amines of the formula I.
- the amount of fat used in the invention determines the degree of softness of the leather.
- the more acid groups of the polymer are modified by the reaction with one or more fatty amines, the softer the leather treated with them. Since the self-emulsifiability of the resulting polymer is influenced, not all carboxyl groups of the polymer should be reacted in this way. In experiments, the conversion of an amount of 20 to 80 mol%, based on the carboxyl groups present in the polymer, has proven to be advantageous.
- the length of the alkyl chain has an influence on the softness that can be achieved.
- alkyl chains with 12-30 C atoms make the agents usable.
- fatty amines with a Carbon number between 16 and 22 preferred.
- the use of oleylamine and stearylamine for the polymer-analogous reaction is particularly preferred.
- the reaction of the polymers with the fatty amines is preferably carried out in the presence of acidic catalysts, for example with p-toluenesulfonic acid.
- acidic catalysts for example with p-toluenesulfonic acid.
- the amount of catalyst should not exceed 1 mol%, based on the carboxyl groups present.
- the duration of the "ketress depends on the desired conversion, which can be monitored for example by thin layer chromatography and should be greater than 90%.
- the reaction temperature is between 60 and 200 ° C., a reaction under reduced pressure being advantageous in particular at a lower reaction temperature. To achieve sales of more than 99%, it may be necessary to remove the water of reaction formed azeotropically.
- Step C Conversion of residual fatty amine to N-substituted- ⁇ -aminopropionic acids This optional step is carried out if a particularly low residual amine content in the end product is required. The remaining amines are reacted with (meth) acrylic acid and, if appropriate, the amines not bound to the polymer from A) or the N-substituted aminopropionic acids formed are acylated. The details of this reaction are described in DE 37 17 961 C2. An advantage of this step is that in this way it is not absolutely necessary to achieve low amounts of residual amine during step B, which is why it is also possible to work with the fatty amine in excess, that is to say with more than 80 mol%, based on carboxyl groups.
- Step D neutralization and dispersion
- the remaining carboxyl groups are partially or completely neutralized with dilute base, if appropriate with the addition of water, wherein the polymer is dispersed or dissolved.
- Suitable neutralizing agents are alkali and alkaline earth metal hydroxides, ammonia, amines or amino alcohols.
- the amount of base is chosen so that a pH between 5 and 9 is established.
- the aqueous emulsions according to the invention are adjusted to a solids content of 20 to 80% by weight.
- the invention further relates to the use of the agents according to the invention for the production of upper leathers with a low content of volatile volatile constituents, in particular eupholstery leathers.
- the agents according to the invention which contain the modified polymers, can be used either as such or in combination with other fatliquoring agents in the manufacture of car upholstery leathers.
- the products according to the invention are also suitable for the production of hydrophobic upper leathers or washable clothing leathers.
- the amount of the products used is 2 to 20% by weight, preferably 5 to 15% by weight, based on the shaved weight of the leather. They are usually used in the greasing stage of leather processing.
- Feed 3 0.5 g (3.0 mmol) of azo-bis-isobutyronitrile in 15 g of butyl glycol
- the dosing time is approximately one hour.
- the mixture is stirred at 80 ° C. for a further 30 minutes and then 58 g (0.22 mol) of oleylamine and 0.4 g of p-toluenesulfonic acid are added.
- the temperature is raised to 150 ° C. and the batch is stirred for 4 hours, 15 g of distillate being removed in the process.
- the mixture was examined by thin layer chromatography. There was a residual amine content of 5% based on the total product, corresponding to a conversion of approximately 85%. It was cooled to approx. 95 ° C. This was followed by the addition of 2.0 g of acrylic acid, followed by the addition of 1.8 g of maleic anhydride.
- Example 1 was repeated, but 0.5 g of hypophosphorous acid was added as a catalyst for the amidation. There was a residual amine content of 0.8% after the polymer-analogous amidation, which is why the reaction with acrylic acid and MA was dispensed with. A clear yellow product with an active substance of 40% by weight and a pH of 6.6 was obtained.
- Example 1 was repeated, but 110 g of oleylamine (0.42 mol) were used. The result was a yellow emulsion with a pH of 7.5 and an active substance of 40% by weight.
