Description
Technical field
The present invention relates to tanning chemistry and field of engineering technology, more particularly to a kind of Huang based on Zirconium-aluminum-titanium cooperation tanning agent
Bovine cerebellum less chrome tannage method.
Background technology
Now, leather industry pollution of chromium problem enjoys social concerns, puts into effect within 2014《Process hides and fur manufacturing industry water
Pollutant emission standard》Total chrome content must not exceed 1.5mg/L, sexavalence in regulation, the comprehensive wastewater of existing leather-making enterprises discharge
Chromium content need to be less than 0.2mg/L.The increasingly strict use for causing chrome tanning of environmental protection policy regulation is restricted, and this is also constrained
The development of leather industry.Therefore, reducing the pollution of chromium, develop the less chrome tannage technology cleaned, be both the great demand of country,
The inexorable trend of leather industry sustainable development is realized, is also the target that leather industry is dreamed of.
More the less chrome tannage technology of maturation is following three kinds at present：1）Vegetable tanning agent-chromium Combined tanning, by vegetable tanning
Agent be modified after with chrome tanning agent combination tanning, utilize between plant polyphenol and chromium synergy raising tanning agent tanning effect；
2）Organic tanning agent-chromium Combined tanning, carries out pre-tanning by using acrylic resin, aldehydes tanning agent, improves state before collagenous fibres tan,
More functional groups are introduced in skin, the purpose for promoting chrome tanning agent infiltration, improving Percentage bound is played；3）Chromium-non-chromium metal is combined
Tannage, using the synergy between many metals, plays each independent tanning advantage of metal, improves the aesthetic quality of finished leather.
By introducing few chrome tanning technology in cow leather upper leather production, tanning production pollution of chromium problem is not only alleviated, is accorded with
Close national requirements for environmental protection.The addition of new material can also assign finished leather more characteristics simultaneously so that the integrated quality of upper leather is obtained
To further lifting, the growing consumption demand of people is met, is significant for upper leather Future Development.
The content of the invention
Therefore, for it is above-mentioned the problem of, the present invention propose it is a kind of based on Zirconium-aluminum-titanium coordinate tanning agent cattle hide upper leather it is few
Chromium process for tanning, it is described to coordinate the cattle hide upper leather less chrome tannage method of tanning agent not only to reduce tanning production based on Zirconium-aluminum-titanium
The consumption of middle chromium, reduction chromium discharge, mitigates harm of the chromium to environment, meanwhile, the combination property of existing cattle hide upper leather can be lifted,
It is a kind of high benefit clean environment firendly production technology.
To realize above-mentioned technical problem, the solution that the present invention takes is：It is a kind of that tanning agent is coordinated based on Zirconium-aluminum-titanium
Cattle hide upper leather less chrome tannage method, comprises the following steps：
Step 1, take and cut open the grey alkali skin after layer and weigh, as deliming, softening, pickling, tanning process meter material foundation,；
Step 2, the grey alkali skin after layer is cutd open according to common process deliming, softening, pickling, pickling terminal pH is 2.5-2.7；
Step 3, tanning：In rotary drum under the conditions of 25 DEG C of bath temperature, grey alkali tare weight amount 1%-3% grease material or aldehyde is added
Class material process pickled pelt, is rotated 30 minutes；Then with the chrome tanning agent that grey alkali tare weight amount 1%-3% is added in bath, 1.5- is rotated
2.5 hour；Coordinate tanning agent with the Zirconium-aluminum-titanium that grey alkali tare weight amount 10%-20% is added in bath, rotate 2-3 hours；Stop rousing standing
Overnight；After next day rotates 30 minutes, the sodium formate of grey alkali tare weight amount 1% is added, is rotated 20 minutes；Again with 1:It is small that 20 water dissolve
Soda solution carries alkali, and it is 4.0-4.2 to make terminal pH；50-60 DEG C of hot water of grey alkali tare weight amount 100% is added, makes the liquor ratio of body lotion
2.0 are reached, bath temperature is risen to 40 DEG C, continuation is acted on 3-4 hours, goes out drum, horse is taken and stands 48 hours；
Step 4, stand after crust leather water squeezing, shaving, weigh, be used as follow-up hygrometric state dyeing and finishing workshop section meter material foundation；
Step 5, hygrometric state dyeing and finishing：Shaving leather weight 8%-18% syntans, shaving leather are added in hygrometric state dyeing and finishing workshop section
Weight 3%-7% vegetable tanning agent, shaving leather weight 12%-16% fatting agent processing crust leather；
After step 6, hygrometric state dyeing and finishing terminate, dry state ornamenting is carried out according to common process.
It is further that the grease material in step 3 is cationic fatliquor, anionic fatting agent, non-ionic
At least one of fatting agent.
It is further that the aldehydes material in step 3 is at least one of formaldehyde, glutaraldehyde, aldehydic acid.
It is further that the chrome tanning agent in step 3 is commercial goods, its chromic oxide content is 23% ± 2%；It is described it
Zirconium-aluminum-titanium coordinates tanning agent to be the product that Jin Kun Chemical Co., Ltd.s of Mianzhu City produce, and its total oxide content is 9% ± 2%.
It is further that the syntans in step 5 is acrylic compounds tanning agent, amino resins class tanning agent, phenol sulfonic acid class tan
At least one of agent, aldehydes tanning agent.
It is further that the vegetable tanning agent in step 5 is wattle extract tanning agent, myrica extract tanning agent, nutgall tannin extract
At least one of tanning agent, valonea extract tanning agent, quebracho extract.
It is further that the fatting agent in step 5 is lanolin fatting agent, fish oil fatliquoring agent, lecithin fatting agent, plant
At least one of oily fatting agent, mineral oil fatting agent, synthetic fat liquor.
By using preceding solution, the beneficial effects of the invention are as follows：That designs as described above is matched somebody with somebody based on Zirconium-aluminum-titanium
Close the cattle hide upper leather less chrome tannage method of tanning agent has following advantage compared to prior art：1st, chrome tanning agent consumption is only in tanning
For the 30%-40% of common process consumption, waste tanning liquor chromium content reduces 80%, mitigates tanning production pollution of chromium；2nd, gained crust leather color
Pool is light, grain is flat thin, available for the production for producing full grain, nappa leather, falling the top grade leather such as upper leather naturally；3rd, finished leather is obtained
Leather rate is high, can increase Business Economic Benefit.
