Description
Technical field：
The present invention relates to leather coating, and in particular to a kind of preparation method of the formula of aqueous nitrocellulose gloss oil.
Background technology：
Middle bloom nitrocotton gloss oil is the structure composition of oil-in-water (O/W) a kind of, for the face coat of leather, plays increasing
Strong physical property, lifts brightness, improves feel.In the market is the solvent-borne type nitrocotton gloss oil used earliest, and pollution is big, easily catches fire,
Than relatively hazardous.Major part factory all selects water-based nitrocotton gloss oil at present, and there is the technology of maturation in external major company, but domestic
Nitrocotton have unstable, the holding time is short, and easily the defects of demulsification, in order to solve the above-mentioned technical problem, spy proposes a kind of new
Technical solution.
The content of the invention：
In place of overcoming above-mentioned the shortcomings of the prior art, and provide a kind of aqueous nitrocellulose
The preparation method of the formula of gloss oil.
The technical solution adopted by the present invention is：A kind of formula of aqueous nitrocellulose gloss oil, the component of the formula is nitrocotton,
Water, isooctyl acetate, plasticizer DOA, castor oil and EL series emulsifying agents；The parts by weight of the formula each component are nitrocotton
25-60 parts, 100-200 parts of water, 200-300 parts of isooctyl acetate, 5-40 parts of plasticizer DOA, 10-30 parts of castor oil and EL systems
5-35 parts of row emulsifying agent.
The parts by weight of the formula each component are 30-50 parts of nitrocotton, 150-180 parts of water, isooctyl acetate 250-280
Part, 10-30 parts of plasticizer DOA, 15-25 parts of castor oil and 10-20 parts of EL series emulsifying agents.
The plasticizer DOA is hexanedioic acid dioctyl ester.
The EL series emulsifying agent is castor oil polyoxyethylene ether.
The digestion cotton source does not have special limitation, belongs to the deep processed product of agriculture cotton, can be bought by market
Obtain, but to avoid the unstable of production product, preferably select areal, same factory, the product of same viscosity.
A kind of preparation method of the formula of aqueous nitrocellulose gloss oil, this method comprise the following steps：
Step 1: the different monooctyl ester of solvent acetic acid and nitrocotton are added in reaction kettle, high-speed stirred is until nitrocotton is all molten
Untill untill solution；
Step 2: reactant adds plasticizer DOA, castor oil and EL series emulsifying agents into step 1, continue to stir, stir
The time is mixed as 10-40 minutes, is shut down afterwards within 10-40 minutes；
Step 3: water is slowly added into the inside of reaction kettle, when standing 1-2 is small；
Step 4: last high-speed stirred emulsification, obtains required product.
The shape of the reaction kettle has certain requirement, and inner wall cannot have dead angle and barrier liquid material quick rotation
Stent, when dispersion impeller rapidly rotates, liquid has to form certain whirlpool, and liquid and dispersion impeller can just had and sufficiently connects
Touch, so as to form necessary shearing force, make small, the product that gained is stablized of the particle of emulsification as far as possible.
Beneficial effects of the present invention are：Leather finishing agent provided by the invention has higher Bearable dry and wet wipe and comfortable hand
Sense；The glossiness of leather, polish retention, resistance to bent rich property can be kept, makes the leather hand feeling after processing comfortable, nature and is not had
Plastic sense；And in this formula in without the organic solvent such as alkylphenol polyoxyethylene ether class compound, safety and environmental protection.
Embodiment：
The present invention is further described in conjunction with specific embodiments：

For hexanedioic acid dioctyl ester.The EL series emulsifying agent is castor oil polyoxyethylene ether.The digestion cotton source is not special
Limitation, belong to the deep processed product of agriculture cotton, can be bought and obtained by market, but to avoid the unstable of production product,
Preferably select areal, same factory, the product of same viscosity.
Embodiment two：
A kind of formula of aqueous nitrocellulose gloss oil, the parts by weight of the formula each component are the 25-60 of resistance to nitrocotton parts, water
25 parts of 150 parts, 250 parts of isooctyl acetate, 20 parts of plasticizer DOA, 20 parts of castor oil and EL series emulsifying agent.The plasticising
Agent DOA is hexanedioic acid dioctyl ester.The EL series emulsifying agent is castor oil polyoxyethylene ether.The digestion cotton source does not have
Special limitation, belongs to the deep processed product of agriculture cotton, can be bought and obtained by market, but to avoid the shakiness of production product
It is fixed, preferably select areal, same factory, the product of same viscosity.
Embodiment three：
A kind of formula of aqueous nitrocellulose gloss oil, the parts by weight of the formula each component are resistance to 60 parts of nitrocotton, water 200
Part, 300 parts of isooctyl acetate, 40 parts of plasticizer DOA, 30 parts of castor oil and 35 parts of EL series emulsifying agent.The plasticizer
DOA is hexanedioic acid dioctyl ester.The EL series emulsifying agent is castor oil polyoxyethylene ether.The digestion cotton source is without spy
Different limitation, belongs to the deep processed product of agriculture cotton, can be bought and obtained by market, but to avoid the shakiness of production product
It is fixed, preferably select areal, same factory, the product of same viscosity.
Three above embodiment is prepared using following preparation method：
A kind of preparation method of the formula of aqueous nitrocellulose gloss oil, this method comprise the following steps：
Step 1: the different monooctyl ester of solvent acetic acid and nitrocotton are added in reaction kettle, high-speed stirred is until nitrocotton is all molten
Untill untill solution；
Step 2: reactant adds plasticizer DOA, castor oil and EL series emulsifying agents into step 1, continue to stir, stir
The time is mixed as 30 minutes, is shut down afterwards within 30 minutes；
Step 3: water is slowly added into the inside of reaction kettle, when standing 1.5 is small；
Step 4: last high-speed stirred emulsification, obtains required product.
The shape of the reaction kettle has certain requirement, and inner wall cannot have dead angle and barrier liquid material quick rotation
Stent, when dispersion impeller rapidly rotates, liquid has to form certain whirlpool, and liquid and dispersion impeller can just had and sufficiently connects
Touch, so as to form necessary shearing force, make small, the product that gained is stablized of the particle of emulsification as far as possible.
The different monooctyl ester of solvent acetic acid and nitrocotton are added in reaction kettle, high-speed stirred allows it fully to dissolve, when otherwise spraying
It can get ready or rough surface, not reach high glossiness.Plasticizer DOA and castor oil are added, EL series emulsifications, continue to disperse,
Diluent and stabilizer is allowed to be mixed thoroughly with the nitrification cotton pulp accomplished fluently, while EL series emulsifications are also uniformly dispersed, and EL
Each component in the lipophilic group and oil phase of series emulsification emulsifies together, then water is slowly added into the bottom of reaction kettle, stand to
Give digestion time；Last high-speed stirred emulsification, water phase and oil phase dispersion and emulsion at high speeds, becomes oil-in-water (O/W)
White emulsion, obtains final product；More stable oil-in-water shape lotion.
Using effect is tested：
This research investigates the effect of the preparation method of the formula of aqueous nitrocellulose gloss oil by 100 enterprises, surveys
Examination project standards of grading are：Very satisfied 5 points, 4 points are satisfied with, general 3 points, is unsatisfied with 2 points, very dissatisfied 1 point.It is wherein common
