Description
Technical field
The invention belongs to PU leather wet method penetrant, be specifically related to a kind of PU leather abscess straightening agent and preparation method thereof.
Background technology
Artificial leather, synthetic leather are important component parts of plastics industry, are widely used in national economy every profession and trade.Artificial leather, synthetic leather were produced existing 60 years development history in the world, and China started development and production artificial leather from 1958, and it is the industry developing early in China Plastics Industry.In recent years, growth, the product yield that manufacturing enterprise's equipment production line is not only in the development of Chinese's fabricate-leather, synthetic leather industry increases year after year, variety design increases every year, and in industry development process, there is oneself a industry organization, there is suitable cohesiveness, thereby can be Chinese's fabricate-leather, synthetic leather enterprise, comprise that relevant industries organize together, develop into an industry that has considerable strength.
After PVC artificial leather, PU synthetic leather being concentrated on studies and developing through sci tech experts more than 30 year, as the ideal substitute of natural leather, has obtained breakthrough technological progress.
PU is applied on the market that fabric face comes across the 1950's the earliest, and by 1964, du pont company developed a kind of PU synthetic leather as upper of a shoe.After Japanese firm has set up the production line of 600,000 square metres of a set of annual outputs, through the continuous research and development of more than 20 years, no matter PU synthetic leather was in product quality, kind, or in output, all obtained increasing rapidly.Its performance more and more approaches natural leather, and some performance even exceedes natural leather, has reached the degree of dividing with the true and false difficulty of natural leather, in the mankind's daily life in occupation of consequence very.
Natural leather is widely used in and produces commodity and industrial goods by people owing to having good natural characteristic, but along with the growth of world population, the demand multiplication of the mankind to leather, a limited number of natural leathers can not meet this demand of people already.For solving this contradiction, scientists begin one's study decades ago exploit person fabricate-leather, synthetic leather, to make up the deficiency of natural leather.50 years of researches historical processes are exactly the process that artificial leather, synthetic leather are challenged to natural leather.
Scientists, from researching and analysing the chemical composition and institutional framework of natural leather, is set about from nitrocellulose varnished cloth, enters into PVC artificial leather, and this is the first generation product of artificial leather.Scientist, on this basis, has done many-sided improvement and exploration, is first the improvement of base material aspect, modification and the improvement of following by coating resin.To 20 century 70s, the nonwoven fabric of synthetic fiber occurs that acupuncture becomes net, is bonded to the techniques such as net, makes base material have lotus root shape section, hollow fiber-shaped, has reached loose structure, and has met the network structure requirement of natural leather; Synthetic leather top layer at that time can have been accomplished micro hole construction layer of polyurethane; be equivalent to the grain of natural leather; thereby the outward appearance of PU synthetic leather and immanent structure and natural leather are progressively approached, and other physical characteristics are all close to the index of natural leather, and color and luster is more more bright-coloured than natural leather; Its normal temperature folding reaches more than 1,000,000 times, and low temperature folding also can reach the level of natural leather.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of PU to remove from office with abscess straightening agent and preparation method thereof, a kind of for regulating orthostatic abscess that PU leather wet method resin bed uses and the organosilicon auxiliary agent of pliability, this product uses and there will be special foam structure and special feel in PU leather wet method manufacturing process, reaches the effect that common abscess agent does not reach in the past.
The object of the invention is to complete by following technical solution.This abscess straightening agent for PU leather, this formula is: anion surfactant DBSA 500KG, nonionic foam stabilizer polyethers 300KG, organic silicone oil surfactant 100KG, fatty alcohol-polyoxyethylene ether AEO-9200KG, water 1500KG, NaOH 20KG, alcohol 200KG.
The preparation method of abscess straightening agent for this PU leather of the present invention, the method step is as follows:
(1), organic silicone oil surfactant is synthetic:
Add 400KG containing hydrogen silicone oil and 1200KG allyl polyether B-1000 to being equipped with in the 2000L enamel reaction pot of thermometer, agitator, condensing unit, pass into nitrogen protection, intensification makes its fusing, then is warmed up to 105 DEG C, stirs and adds organic complex platinum catalyst 500g, control reaction temperature at 120 ~ 130 DEG C, material becomes water white transparency shape in reaction pot, and then rear insulation 2 ~ 3 hours allows its cooling room temperature, can obtain colourless transparent liquid finished product, be organic silicon surfactant;
(2), the neutralization of various surfactants with mix:
Add anion surfactant DBSA 500KG to being equipped with in the 3000L enamel reaction pot of thermometer, agitator, condensing unit, fatty alcohol-polyoxyethylene ether AEO-9200KG, water 1500KG, fully stir one hour, slowly add NaOH 20KG, in and Ph value to 6 ~ 7, then the disposable alcohol 200KG that adds, after stirring, add nonionic foam stabilizer polyethers 300KG, and organic silicone oil surfactant 100KG, after stirring, be finished product.
Mechanism of the present invention: PU wet-process coating is again gel coating, his feature is in the bath of water and DMF, to generate the porous membrane that is similar to corium, far from each other with common artificial leather, its product excellence can replace corium in a lot of fields.The feel of a lot of PU leather was not fully up to expectations in the past, in the present invention, make organic silicon surfactant by oneself, solve the problem with resin and DMF intermiscibility, coordinate conventional surfactant, the technology that has adopted nonionic and anion surfactant mixture, has obtained good synergy, can control process of setting, there is fabulous osmosis, can improve the production efficiency of PU leather.Accelerate the exchange velocity of DMF and water, obtain good foam structure.Particularly organosilicon auxiliary agent add the great seepage velocity that improved, obtained special upright abscess, make de-DMF more thoroughly with fast, the feel of having improved leather can also improve the artificial leather of leather to a certain extent.
Beneficial effect of the present invention is: this product has synthesized the more special organosilicon Surfactant of structure, utilize its ultralow surface tension, superpower surface-activity, abscess and structure to Pu leather have quite special effect, to the feel of Pu leather, there are unexpected benefits, well solve and the compatibility of PU resin, made feel and the corium of the PU leather of making similar.Surfactant is the important component part in coating solution formula, and the speed that when it directly affects freezing film, water spreads in to the speed spreading in film and DMF to coagulating bath, has very important effect to setting rate and quality of forming film.This product has added the surfactant of anion in the process of mixture, and this product has fabulous infiltration and emulsifying effectiveness, and the operating efficiency that improves PU leather is had to good effect.Hydrophobic non-ionic surfactant extends freezing film process, has particularly delayed epithelium surface PU molecule and has formed the time of solid film, thereby for the DMF diffusion at epithelium center has obtained the time, accelerated process of setting.The nonionic foam stabilizer and the anion surfactant that in this product, add have good synergy, have obtained good effect.
