Description
Technical field
The present invention relates to field of compound material, are related to a kind of applied to electrical types such as the vehicles, the mobile phones such as carplane
The fabric of the ranges such as shell, clothes, household items, and in particular to a kind of synthetic leather of permanent efficiently release anion and its
Preparation method.
Background technique
Anion is also negative oxygen ion, refer to obtain extra paired electrons and negatively charged oxygen ion [Sun Wei, in
Hai Yuan, Yao Luxian etc., anion function Materials, Jilin forestry science and technology, 2018,5,35-37].It is generally because of atmosphere
It is influenced by factors such as thunder and lightning, ray, the high speed shear of water flow, photosynthesis, point discharges, ionization occurs and generates.Due to negative
Ion has the function of purify air, anti-oxidant, enhancing is immune etc., enjoys laudatory titles such as " air vitamins " in medical field.In however,
The status faced in state's process of industrialization is that dense population areas vegetation is rare, atmosphere pollution, and air quality index is exceeded.Wherein,
In town and country, especially city, the anion accounting in air is unbalance.
In synthetic leather (PVC leather or PU leather etc.) industry, synthetic leather is exactly not environmentally to the impression of people.Add plasticizer
PVC leather afterwards can lead to the problem of serious organic volatile；And solvent type PU synthetic leather also has the problems such as DMF residual.In addition, right
In automobile interior decoration, many situations of synthetic leather are used in such a confined space of car body, and volatile matter can direct shadow
Ring the health of human body.So exploitation of the synthetic leather in terms of health environment-friendly has been a concern.
Currently, there are some researchers to attempt to improve the formula of synthetic leather, by adding anion-generating material,
To increase the report of negative ion concentration in use environment:
Wuxi Hua Lian Plastic Products Co., Ltd constitutes the mode of backing fabric layers by using anion yarn, is made
Leather with anion releasability, but not yet explicitly [Ji Jianliang permanently releases a large amount of anion human simulations to anion material
Fabricate-leather, 2018, CN107663782A].
Dongguan City Sheng Guo emulational leather Technology Co., Ltd. contains the tender shale of 5-20% or electricity by the way that one layer is added in PU is removed from office
The PU of gas stone or seabed ore particles layer, to achieve the purpose that anion discharges [Zeng Hao, Ye Mengtang, Wang Qiang, a kind of anion ring
Guarantor's synthetic leather structure, 2016, CN205636313U].
PU tree is added in the mixed powder of 35% tourmaline and 65% lanthanide series by three scholar MediaTek Inc. of Beijing
The anion releasing layer among leather is made in rouge, and leather is made to have the function of discharging anion [Zhou Zhanxue, Meng Fansheng, Yi Zhongke
The rtificial leather of Spontaneous release anion, 2015, CN204690463U].
The tourmaline composite wood that Kunshan Achilles Artificial Leather Co., Ltd. passes through the addition 1.5-20% in PVC and PU leather
Material has obtained the antibacterial leather that anion releasability improves about 4 times.400/cm3(air environment) is improved to 1800/cm3
(product).[Cheng Feng, Zhu Yongliang, efficient PVC artificial leather, the PU synthetic leather preparation method for discharging anion, 2005,
CN1654739A]
Sichuan is just reaching biotech inc and the mixed powder of tourmaline and lanthanide series or rare earth element is being added
The primary coat of cow leather and face apply slurry, are allowed to anion releasability highest and improve 25 times.200/cm3(air environment)
It is increased to 5000/cm3(product).[Lu Xianzheng, Lu Kai, Zhu Fangming efficiently discharge the cow leather preparation method of anion,
2015, CN105178028A]
Currently, many anion synthetic leather, only mineral powder it is direct select or with after being simply mixed of other materials,
Reach the ability of anion release using the field effect of mineral powder itself.Although being able to satisfy wanting for permanent release anion
Ask, but the raising for anion releasability, be based particularly on the modification of mineral itself, as tourmaline lattice structure it is micro-
It adjusts, but report is seldom.However, studies have shown that the tourmaline of trigonal system, there are electrostatic fields on surface.In 1000 degree or so of high temperature
After heat treatment, vacancy, distortion of lattice originally in crystal can be eliminated, and electronics displacement can also occur for ion, and crystal structure can occur
Adjustment, surface potential can also change correspondingly, and anion releasability is caused to change.[Li Fangfang, the property of tourmaline and apply exhibition
It hopes, 2007,455,10-13]
Therefore, Environmental Safety, function high efficiency requirement under, be badly in need of researching and developing a kind of be added through fine tuning crystal structure
Electrical stone material reaches the preparation method of the synthetic leather of permanent efficiently release anion.
