Description

A kind of antibacterial type swivel chair synthetic leather and preparation method thereof
Technical field
The present invention relates to antibacterial type swivel chair synthetic leather and preparation method thereof.
Background technology
With the continuous development of society, living standards of the people increasingly improve, people for living environment requirement also increasingly Improve.At present, swivel chair is with synthetic leather is moisture resistance, light fugitive, cracky, it is difficult to reach high-grade decorative effect.For natural leather, Due to being restricted by natural conditions, while the whole world is progressively strengthened to the consciousness for protecting animal, natural leather is reduced year by year. At present, the antibacterial type swivel chair synthetic leather developed on market, generally comprises surface layer and bottom, and surface layer is typically mixed by polyvinyl chloride resin Close the mixing of various modifying agent to form, and bottom is generally fibrage, but, such synthetic leather gas permeability is bad, wear no resistance, Anti-corrosion acid-proof poor performance, feel be not soft, and bottom and surface layer are easily corroded in hot humid environment and divided.On The biocidal property of the swivel chair synthetic leather stated is also bad, and for antibacterial problem, some companies can add bacteriostatic agent antibacterial to be lifted, But, after cyclic washing, the fungistatic effect of swivel chair synthetic leather occurs.
The content of the invention
In place of above-mentioned the deficiencies in the prior art, the problem that the present invention is solved is：One kind is provided through repeatedly washing it The antibacterial type swivel chair synthetic leather of fungistatic effect can be maintained afterwards.
To solve the above problems, the technical scheme that the present invention takes is as follows：
A kind of antibacterial type swivel chair synthetic leather, including bottom and surface layer；Described surface layer is fitted in the both sides of bottom；It is described Surface layer include the component of following weight portion：100 parts of polyvinyl chloride resin, 50 to 60 parts of plasticizer, 20 to 30 parts of aramid fiber, silk 20 to 30 parts of fiber, 5 to 10 parts of ramee, 10 to 20 parts of cotton fiber, 5 to 10 parts of foaming agent；Described bottom includes following The component of weight portion：100 parts of polyvinyl chloride resin, 30 to 40 parts of calcium carbonate, 5 to 10 parts of stabilizer, 5 to 10 parts of polytetrafluoroethylene (PTFE).
Further, the ratio of described cotton fiber and ramee is 2.
Further, in described surface layer, aramid fiber and silk fiber ratio of weight and number are 0.8 to 1.2.
Further, in described surface layer, aramid fiber and silk fiber ratio of weight and number are 1.
Further, described polytetrafluoroethylene (PTFE) weight portion is 6 to 8 parts.
The preparation method of one antibacterial type swivel chair synthetic leather, step are as follows：
(1) preparation of bottom：
A, each component of bottom is stirred into mixing in mixer according to weight portion；
B, mixed material is carried out kneading, mill, calendering, obtain bottom；
(2) preparation of surface layer：
A, add water in the mixture of aramid fiber and silk fiber according to weight portion, carry out in being then placed in pulper broken Solution, obtains mixed slurry；Then mixed slurry is sent in beater and is beaten, obtain free shape fiber pulp；Finally will trip From shape fiber pulp through squeezing, drying, stand-by dry mixed fiber pulp is obtained；
B, ramee and cotton fiber are mixed according to weight portion, add water in the mixture, be then placed in pulper In carry out size degradation, obtain antibacterial mixed slurry；Then antibacterial mixed slurry is sent in beater and is beaten, obtain free shape Bacteriostatic fiber is starched；Finally by free shape bacteriostatic fiber slurry through squeezing, drying, the antibacterial composite fibre slurry of stand-by drying is obtained；
C, by dry mixed fiber pulp, the antibacterial composite fibre slurry of drying, polyvinyl chloride resin, plasticizer, foaming agent feeding rabble furnace In carry out heating stirring；
D, well-beaten mixed material in C is carried out kneading, mill, calendering, obtain surface layer；
(3) hot pressing is combined：
By bottom and surface layer as on compounding machine, through preheating, flattening, laminating, refrigerating work procedure, synthetic leather is obtained.
Further, the mixing time in the step of prepared by bottom a is controlled in 40 to 50min.
Further, the step of the preparation of the surface layer in A and step B, the beating degree of beater is 65 to 70 ° of SR, is beaten Time is 30 to 40min.
Further, the step of the preparation of the surface layer, in B, mixing time is 20 to 30min, controls temperature for 140 to 160 ℃。
Beneficial effects of the present invention
The present invention adds ramee and cotton fiber in surface layer, as ramee top is pointed, has prodding and itching feeling, So swivel chair synthetic leather is not typically used in, but ramee can also keep very high biocidal property after repeatedly washing Can, by cotton fiber and the rational ratio setting of ramee, the prodding and itching feeling of ramee can be eliminated, increase the softness of surface layer Comfort level.The present invention is mixed with two kinds of specialty fibers in the polyvinyl chloride resin of surface layer, and aramid fiber intensity is high, acidproof corrosion-resistant；Silkworm Silk fiber moisture absorption, scattered wet performance are good, and gassiness, permeability are strong, surface smooth uniform, bright and clean grace；By aramid fiber and silk Fiber can increase the gas permeability and wearability of surface material simultaneously, reach the purpose of soft touch again by rational ratio. In order to prevent the corrosion oxidation phenomenon of bottom and surface layer joint face, the polytetrafluoroethyl-ne of reasonable weight portion is added in primer Alkene, can effectively prevent the corrosion of bottom and surface layer joint face.The invention is strong, and distinct characteristics increased comprehensively Gas and wearability, and make bottom and surface layer be not easy corrosion division is subject in hot humid environment.
