Abstract
The invention relates to a preparation method of a high-efficiency penetrant for PU (polyurethane) synthetic leather. The method comprises the following steps: A, synthesis of maleic dioctylester sulfoacid sodium; B, synthesis of organosilicon low-surface-tension silicone oil: 200KG heptamethyltrisiloxane and 500KG B-600 polyether are added into a 1000L enamel reaction kettle and heated to 80 DEG C, a catalyst, namely chloroplatinic acid, is added, the temperature is controlled between 125 DEG C and 130 DEG C for three hours, then a clear and transparent material is the finished organic low-surface-tension silicone oil; and C, mixing: 1500KG maleic dioctylester sulfoacid sodium and 200KG organosilicon low-surface-tension silicone oil are added into a 2000L enamel reaction kettle, 400KG to 500KG water is added according to a sampling test penetration rate, and stirred uniformly, and the finished penetrant is obtained. The preparation method has the benefits that the running speed of a synthetic leather wet process technology is increased; the product performance of the synthetic leather is improved; and the penetrant particularly exerts a production accelerating specialty effect that a common synthetic leather auxiliary agent cannot exert when the penetrant is used in clothing leather of the PU synthetic leather.
Description
Technical field
The invention belongs to, be specifically related to a kind of preparation method of PU use for synthetic leather high-efficient penetrant.
Background technology
The wet polyurethane synthetic leather is to occur on the market abroad in 1963, and its performance, structure are compared with dry-method chemical leather, in permeability obvious improvement are arranged aspect visual appearance.Its crux is how to control replacement process, wherein tensio-active agent is important integral part in the coating solution prescription, the speed that water spread in to the speed of film internal diffusion and DMF to precipitation bath when he directly affected freezing film has act, very important effect to setting rate and quality of forming film.
Good solvent (DMF) and the another kind of non-solvent (water) of a kind of PU of the very simple selection of mechanism of wet method gel coating technique film forming, with DMF PU is dissolved into solution first, be coated with or be immersed on the base cloth, immerse water or contain in the aqueous solution of DMF, utilize the compatibility of DMF and water, allow water at coated membrane internal conversion DMF, reduce the concentration of DMF, impel the PU film forming, its key is how to control replacement process, this wherein auxiliary agent played suitable crux, particularly utilize the excellence of the good penetrating quality of permeate agent and specific organic silicon surfactant reduce surface tension characteristics be this patent uniqueness find.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of preparation method of PU use for synthetic leather high-efficient penetrant is provided.
The objective of the invention is to finish by following technical solution.The preparation method of this PU use for synthetic leather high-efficient penetrant, the method step is as follows:
Synthesizing of A, dioctyl maleate sodium sulfonate:
One, esterification technique
In the enamel reactor of 2000L, drop into secondary octanol 252KG, MALEIC ANHYDRIDE 200KG, catalyzer is to toluic acid, 2KG, then airtight pot cover is opened stirring, the open cold condenser, and insulation is one hour under 90 to 100 degree, then suck the 250KG isooctyl alcohol, be warmed up to 140 degree, be incubated post-tensioning vacuum hydro-extraction in one hour, deviate from rear sampling chemical examination and be cooled to 80 after qualified to spend the left and right sides stand-by to anhydrous;
Two, process for sulfonation
Open the enamel reactor of 2000L, add Sodium Pyrosulfite 300KG, distilled water 1000KG, closed reactor is opened steam and is heated up, and preservation and controlling is at temperature 125 to 130 degree, pressure-controlling is incubated about 8 hours in 2 kilograms, after insulation finishes, reduce the temperature in 60 degree, bleed off pressure, add the ethanol of 100KG, stir, sample examination both had been dioctyl maleate sodium sulfonate finished product after qualified;
Synthesizing of B, organosilicon low surface tension silicone oil:
Drop into the 200KG heptamethyltrisiloxane in the enamel reaction still of 1000L, B-600 polyethers 500KG is warmed up to 80 degree, add the catalyzer Platinic chloride, to 130 degree, it is as clear as crystal to be incubated after three hours material, is organic low surface tension silicone oil finished product at 125 degree for the control temperature;
C, mixing:
Add dioctyl maleate sodium sulfonate 1500KG in the enamel reaction still of 2000L, add organosilicon low surface tension silicone oil 200KG, according to sampling chemical examination rate of permeation, add 400 to 500KG water, stirring both is the finished product of permeate agent.
Beneficial effect of the present invention is: dioctyl maleate sodium sulfonate trade(brand)name dioctyl maleate sodium sulfonate (being commonly called as penetrant t), claim again Aerosol OT, belonging to aniorfic surfactant, is a kind of high-efficient penetrant, has good wetting and penetrating quality.Because it is functional, be widely used.Application quantity is very large aspect weaving and leather especially, be applied in the PU leather wet processing, utilize its perviousness, in wet processing, mainly play the effect of the exchange of accelerating DMF and water, the dioctyl maleate sodium sulfonate of producing among the present invention takes full advantage of the property of raw material of secondary octanol and isooctyl alcohol, mix to use and reduced production cost, it is low-cost to have produced high density, the factory effluent amount reduces by 90 percent high-performance permeate agent than old technique, be common tensio-active agent but be limited to this permeate agent, it reduces capillary limited in one's ability, the present invention has synthesized again good low surface tension silicone oil, the two is used in PU synthetic leather wet processing, utilize the length of the two, improved the driving speed of synthetic leather wet processing, improved the product performance of synthetic leather, in the clothing leather of PU synthetic leather, use especially, played the faster production singularity effect that common synthetic leather auxiliary agent does not have.
