Abstract
The invention relates to a bubble regulator used for wet synthetic leather. The compositions in portion by weight of the bubble regulator are: 10 to 15 portions of sodium dodecyl benzene sulfonate, 30 to 50 portions of alkylphenol polyethenoxy ether, 5 to 15 portions of oleic acids, 5 to 10 portions of polyether modified silicon oil and 15 to 45 portions of water. When the bubble regulator is used for the wet synthetic leather, the performance of the wet synthetic leather can be obviously improved and the synthetic leather can have the effect close to corium.
Description
Technical field
The invention belongs to the wet-method synthetic leather field, particularly relate to a kind of size and connective auxiliary agent that is used to regulate the abscess that the wet-method synthetic leather resin layer forms.
Background technology
The PU synthetic leather is the macromolecular material of imitation natural leather internal structure and application performance, normally the perforated nonwoven fabrics with dipping is a reticular layer, the microvoid polyurethane resin is a grain layer, its outward appearance is all similar to natural leather with internal structure, elasticity is moderate, having certain elongation and ventilation property, is the optimal substitute material of natural leather.But some performance of Synthetic Leather still is unable to catch up with natural leather far away, as the waterproofing and moisture-penetration performances and the comfort of natural leather, with the footwear that Synthetic Leather is made, can not absorb and get rid of the sweat that pin produces, and can make feel feel uncomfortable.Desire improves the Synthetic Leather product performance, makes it more near natural leather, and the performance of polyurethane synthetic leather grain surface paste is crucial.Grain surface paste is major ingredient with the urethane resin, and urethane resin itself easily forms fine and close rete, makes synthetic leather emulation skin degradation.In order to improve the problems referred to above, people have carried out a large amount of work, as utilize effusion pore-creating on the polyurethane synthetic leather grain surface layer of solvent, the synthetic resins that uses other, modified polyurethane resin or the like.
Wet-method synthetic leather is meant the synthetic leather that adopts the wet processes method to prepare, promptly go in woven or the woven cloth with the DMF solution impregnation of polyurethane resin composition or coating in the above, in the precipitation bath that then it is immersed in the water precipitation bath or forms by the mixing solutions of DMF-water, after making urethane resin be frozen into vesicular, it is handled by washing and drying process.Concerning wet-method synthetic leather, can be by increasing the purpose that its abscess improves its performance.The connectedness of abscess is good more, volume is big more, and then the performance of wet-method synthetic leather is good more; In addition, after abscess increases, also can make wet-method synthetic leather be easier to the embossing typing; The benefit of bringing to production is the production rice number that can increase the PU leather.
In the prior art, the abscess conditioning agent that is used for wet-method synthetic leather commonly used is a Sodium dodecylbenzene sulfonate, Sodium dodecylbenzene sulfonate (SDS) is as a kind of pore forming material, has the advantage fast, that bubble stability is good of bubbling, but the bubble that the SDS effect produces down is less, do not satisfy the requirement of wet-method synthetic leather to big abscess, also there is identical problem in other pore forming material when using.
Summary of the invention
Technical problem to be solved by this invention provides a kind of processing agent for wet-method chemical leather, it can increase the volume of abscess in the wet-method synthetic leather fiber and the connectedness between the raising abscess this abscess conditioning agent, thereby finally make synthetic leather have good performance, more approach the effect of corium.
For solving above technical problem, the present invention takes following technical scheme:
A kind of processing agent for wet-method chemical leather, by weight, its prescription is as follows:
10～15 parts of Sodium dodecylbenzene sulfonatees;
30～50 parts of alkylphenol polyoxyethylene;
5～15 parts of oleic acid;
5～10 parts of polyether modified silicon oils
15～45 parts in water.
The screening formulation of above-mentioned processing agent for wet-method chemical leather is as follows:
12～14 parts of Sodium dodecylbenzene sulfonatees;
35～45 parts of alkylphenol polyoxyethylene;
8～10 parts of oleic acid;
5～8 parts of polyether modified silicon oils;
25～30 parts in water.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
Abscess conditioning agent of the present invention is made up of good pore forming material (Sodium dodecylbenzene sulfonate), defoamer (alkylphenol polyoxyethylene and polyether modified silicon oil) and solvent system (oleic acid, water), the adding of defoamer can effectively improve the Sodium dodecylbenzene sulfonate lather quickness, make that the abscess that forms is better connective, the abscess of acquisition is bigger; Rationally composite between each component then when making that the abscess that forms has comparatively large vol, guarantees the stability of the big abscess that forms.This abscess conditioning agent is used for wet-method synthetic leather can significantly improve its performance, synthetic leather is had approach the effect of corium.
Embodiment
The present invention will be further described in detail below in conjunction with specific embodiment.
Embodiment 1:
Synthetic prescription with the abscess conditioning agent according to present embodiment is:
Sodium dodecylbenzene sulfonate 13 grams, alkylphenol polyoxyethylene 40 grams, oleic acid 10 grams, polyether modified silicon oil 7 grams, water 30 grams.
Synthetic production technique with the abscess conditioning agent is as follows:
By weighing Sodium dodecylbenzene sulfonate 13 grams of filling a prescription, alkylphenol polyoxyethylene 40 grams, oleic acid 10 grams, polyether modified silicon oil 7 grams, under 70 ℃, mix and stir, add entry 30 grams then and continue stirring, after about 50 minutes, stop to stir, cooling gets product.
Embodiment 2:
Synthetic prescription with the abscess conditioning agent according to present embodiment is:
Sodium dodecylbenzene sulfonate 14 grams, alkylphenol polyoxyethylene 45 grams, oleic acid 8 grams, polyether modified silicon oil 5, water 25 grams.
Should syntheticly use the production technique of abscess conditioning agent the same.
In order to prove that abscess of the present invention increases effect, has carried out following contrast experiment:
Consumption when abscess conditioning agent product of the present invention is used for wet-method synthetic leather be the wet-method synthetic leather resin weight 1.0～2.5%.
The abscess conditioning agent, the abscess conditioning agent of embodiment 2, the SDS that when the preparation wet-method synthetic leather, in the DMF of polyurethane resin composition solution, add the embodiment 1 of same amount respectively, under the identical condition of other processing condition, the abscess mean size is with the abscess of SDS gained leather 2～3 times in the leather of embodiment 1 and embodiment 2 preparations.
As from the foregoing, abscess conditioning agent of the present invention is used for the effect that wet-method synthetic leather has highly significant, and in addition, practice is proof also, and abscess conditioning agent of the present invention also can improve simultaneously the flexibility and the handle effect of wet method leather.
