Background technology
Solvent borne polyurethane is synthetic needs solvent more, toxicity is larger, and environment is had to larger pollution, and more and more higher quality requirements is to facilitate the inexorable trend of synthetic leather product of new generation in market development to product for the trade barrier of synthetic leather in environmental protection and consumer.
At present, the application of synthetic leather on commodity and industrial goods is more and more extensive, but there is the defect of the poor and poor fire of yellowing resistance in synthetic leather, can not finely be applied to the decoration aspect.
?
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the ventilative leather of a kind of water-based.
The ventilative leather of a kind of water-based, it is characterized in that it adopts dry method to move the film processing method and makes, comprise the steps: to apply waterborne polyurethane resin slurry surface layer on release liners, carry out medium-wave infrared heating and heated-air drying, then apply the bottom tack coat, bonding leather base cloth, carry out medium-wave infrared heating and heated-air drying, and cooling bundling makes finished product.
The ventilative leather of described a kind of water-based, is characterized in that described waterborne polyurethane resin slurry surface layer made by the raw material of following parts by weight: 100 parts of waterborne polyurethane resins, 3～20 parts of aqueous color pastes; 0.5～3 part of water-based thickener, 1～8 part of aqueous foaming agent, 1～8 part of water-based foam stabilizer, 0.5～5 part, curing agent, 0.5～2 part of environment-friendly type phosphorus flame retardant.
The ventilative leather of described a kind of water-based, is characterized in that described waterborne polyurethane resin slurry surface layer made by the raw material of following parts by weight: 100 parts of waterborne polyurethane resins, 5～15 parts of aqueous color pastes; 1～2 part of water-based thickener, 3～5 parts of aqueous foaming agent, 3～5 parts of water-based foam stabilizers, 2～4 parts, curing agent, 1～2 part of environment-friendly type phosphorus flame retardant.
The ventilative leather of described a kind of water-based, is characterized in that it is that base stock is synthetic that described waterborne polyurethane resin adopts polytetrahydrofuran diol and isophorone diisocyanate.
The ventilative leather of described a kind of water-based, is characterized in that it is raw material that described bottom tack coat is used aqueous polyurethane, and add water-based thickener.
The ventilative leather of described a kind of water-based, is characterized in that described water-based thickener is one or more in polyacrylate, polyvinylpyrrolidone, non-ionic water-soluble polyurethane association type emulsion.
The ventilative leather of described a kind of water-based, is characterized in that described aqueous foaming agent is the water-soluble blowing agent of stearic acid amine.
The ventilative leather of described a kind of water-based, the preparation method who it is characterized in that described waterborne polyurethane resin slurry surface layer is as follows: by waterborne polyurethane resin, aqueous color paste and other aqueous promoter add in foaming machine and stir in proportion, regulate the viscosity of foamed slurry by the addition of thickener in whipping process, after viscosity regulates, whether the color of observing foamed slurry is required color, if variant, just continue to add aqueous color paste to be regulated, after having foamed, must observe its foam structure in the laboratory drying, undesirablely to structure also must do corresponding adjustment, until meet the quality of finished product synthetic leather requirement.
The ventilative leather of described a kind of water-based, it is characterized in that it is 5～20m/min that described dry method is moved the speed of a motor vehicle of film processing method, surface layer one is coated with gap thickness is set is 0.05～0.15mm, first paragraph baking oven length is 25～35 meters, 30 ℃ ~ 70 ℃ of medium-wave infrared temperature, heated-air drying temperature 60 C ~ 120 ℃, bottom two is coated with gap thickness is set is 0.05～0.15mm, second segment baking oven length is 25～35 meters, outer 30 ℃ ~ 70 ℃ of the red temperature of medium wave, heated-air drying temperature 60 C ~ 120 ℃.
It is the synthetic waterborne polyurethane resin of base stock that the present invention adopts polytetrahydrofuran diol (PTMG) and isophorone diisocyanate (IPDI), meets the requirement of water-based leather anti-yellowing property; Adopt the leather base cloth, make the water-based leather there is fine gas permeability, adopted perforating micropore technique, increased the gas permeability of water-based leather super goodly; Add the environment-friendly type phosphorus flame retardant, effectively solved the poor fire problem.
Mechanical foaming technique is mainly adopted in two ways and is carried out at present: the one, adopt the homogenizer mode, and make foams by stirring, mix, shearing; Another adopts the mechanical foaming machine exactly, by flow controller, thereby allows the water paste of certain volume and the air of certain volume mix and to make foaming body in rotor chamber.The first kind of way simple and fast, be convenient to control, and can observe at any time and formulate the foaming body structure, but be unfavorable for producing in enormous quantities; The second way is applicable to a large amount of production, but abscess is controlled difficult point is arranged, and, because adjust difficulty, loss is larger, is not suitable with the multiple batches of production of small lot.
About the control of mechanical foaming body, be mainly expansion ratio and the foam structure of controlling foaming body, to meet the requirement of finished product.
Because the water of aqueous polyurethane is dispersion, the volatility latent heat of water is the several times of common solvent, the existing Hot Air Drying of simple employing also restricts the raising of production capacity greatly, so, we have adopted the mode of hot-air seasoning and the combination of medium-wave infrared technology on drying technology, the medium-wave infrared light that wavelength is 3.0 ~ 4.0 microns, directly activate hydrone by radiation, thereby the moisture in water-base resin can be realized to the Quick uniform drying, because shortwave and long-wave radiation are larger on the human body impact, and medium-wave infrared is comparatively safe, activate drying water molecule degree moderate, therefore adopt the dry combination of medium-wave infrared and heat engine, both increased stable processing technique, improve production capacity, energy-conservation Cost reduction again.
The present invention, in order to overcome the deficiency of above technical elements, provides a kind of both had good anti-yellowing property, fire resistance, the aqueous polyurethane synthetic leather that has again good permeability.Thereby, the invention provides the manufacture method of synthetic leather, it is applicable to automobile interior trim with sofa and has the gas permeability similar to corium.
The present invention manufactures synthetic leather by directly apply waterborne polyurethane resin solution on the surface of fabric to form film thereon, aqueous polyurethane is to take the binary colloidal system that water is decentralized medium, with solvent borne polyurethane, compare have nontoxic, nonflammable, the advantage such as free from environmental pollution, use polyurethane replace solvents type polyurethane is applied in synthetic leather, not only can solve the residual and VOC pollution problem of DMF, simultaneously, the synthetic leather of use polyurethane processing has its special benefits, owing to containing a large amount of hydrophilic radicals and microcellular structure in epithelium, therefore have ventilative, water vapour permeability and the sense of touch the same with corium, sanitation performance is better, it is green truly, environment-friendly products.
