Abstract
The invention relates to a wet bayes bubble regulator. The compositions in portion by weight of the wet bayes bubble regulator are: 45 to 50 portions of propanediol block polyether, 30 to 35 portions of polypropylene glycol, 8 to 12 portions of fatty acid ester and 1 to 6 portions of dimethyl silicon oil. The wet bayes bubble regulator can be used in production of wet synthetic leather and wet PU resin to improve the air permeability and the moisture permeability of bayes and the synthetic leather; moreover, the bayes can be made to be straighter and have better rebound resilience.
Description
Technical field
The invention belongs to the wet-method synthetic leather field, particularly relate to a kind of be used to the regulate size of abscess on the wet-method synthetic leather bass and the abscess conditioning agent that distributes.
Background technology
The wet type synthetic leather is meant the synthetic leather that adopts the preparation of wet type processing method, promptly go in woven or the woven cloth with the DMF solution impregnation of polyurethane resin composition or coating in the above, it is immersed in the water precipitation bath then, after reaching required setting time, through washing, after taking out oven dry the wet method bass.From the bass forming process as can be known, when PU coating liquid is impregnated in the precipitation bath, double diffusive process has taken place, promptly water is to coating liquid internal diffusion, and DMF is out-diffusion in the precipitation bath simultaneously, and dope layer solidifies.In process of setting, undergo phase transition at first and what solidify is epidermal area, because the raising of epidermal area PU solid content, its density is increasing, and the aperture diminishes, and makes the bidirectional diffusion resistance increase, it is slack-off that coating inside reaches the speed of gelation, PU molecular aggregates, winding make the place formation of close base cloth increase than the probability of big abscess, and hole wall thickens, the coat-thickness attenuation, apparent density increases thereupon, so its breaking tenacity improves, the breathable moisture permeability of bass decreases.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Wet-method base processing agent, and this abscess conditioning agent is added in the PU coating liquid, can make the wet method bass form dense uniform vesicular structure near the place of base cloth.
For solving above technical problem, the present invention takes following technical scheme:
A kind of Wet-method base processing agent, by weight, its prescription is as follows;
45～50 parts of propylene glycol block polyethers;
30～35 parts of polypropylene glycols;
8～12 parts of fatty acid esters;
1～6 part of dimethyl silicone oil.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
The present invention can be used in wet-method synthetic leather production and the wet method PU production of resins, delay the setting rate on synthetic leather surface in the wet method operation, make the wet method bass form dense uniform vesicular structure, thereby improve the breathable moisture permeability of bass and synthetic leather near the place of base cloth; In addition, the present invention also can make bass more very scrape, and rebound resilience is better.
Embodiment
The present invention will be further described in detail below in conjunction with specific embodiment.
Prescription according to the Wet-method base processing agent of present embodiment is;
Propylene glycol block polyether 45 grams;
Polypropylene glycol 35 grams;
Fatty acid ester 10 grams;
Dimethyl silicone oil 1 gram.
The preparation process of above-mentioned Wet-method base processing agent is:
Above-mentioned each component of weighing formula ratio, (stirring velocity 1450rpm) dispersed with stirring and heating to 60 ℃ promptly makes abscess conditioning agent product after 60 minutes at a high speed, and this product is a weak yellow liquid, and effective constituent is more than or equal to 99%.
The consumption of product of the present invention is:
When the PU resin of solid content 30% was 100 parts, addition was 0.3～1.0 part (promptly 1 ton of PU resin adds 3～10 kilograms).
The present invention is used for wet-method synthetic leather production, and the bass that makes is well-pressed, and rebound resilience is good, and breathable moisture permeability is good, and the synthesising leather performance of production is good.
The present invention is applicable to space leather, ball leather, luggage leather, clothing leather, rubs in the products such as line leather.
