Abstract
Disclosed are a light-transmitting artificial leather, a preparation method therefor, and an automobile interior. The preparation method therefor comprises the following steps: mixing a primary raw material containing toner having a particle size of 0.5 to 10 ?m, polymer powder and a plasticizer, and stirring, grinding, filtering and defoaming same to obtain a light-transmitting pigment raw material; mixing the light-transmitting pigment raw material with a secondary raw material containing polymer powder, a plasticizer, a stabilizer and an inorganic additive, and stirring, filtering and defoaming same to obtain a light-transmitting skin layer raw material; and using a base fabric, a glue raw material, a support layer raw material and the light-transmitting skin layer raw material for preparing, so as to obtain an artificial leather semi-finished product formed by the light-transmitting skin layer, a support layer, a glue layer and the base fabric arranged in sequence; and coating a surface treatment agent on the surface of the light-transmitting skin layer, so as to obtain a light-transmitting artificial leather. The toner in the light-transmitting skin layer raw material uses toner having a nano-scale particle diameter, so that the degree to which the toner obstructs light is reduced, and the prepared artificial leather is guaranteed to have a certain light transmittance.
Description
A kind of light-transparent artificial leather and a preparation method therefor, and an automotive interior Technical Field The invention relates to the technical field of artificial leather, in particular to a light-transparent artificial leather and a preparation method therefor, and an incorporation thereof in an automotive interior Background Art Artificial leather is a plastic product that looks and feels like leather and can replace leather.
Characterized by high flexibility and wear resistance, artificial leather can be widely used for bag production and automotive interior decoration.
With the development of the automotive interior industry, people have increasingly high requirements for the automotive interior atmosphere and human-vehicle interactions. Owing to its unique material characteristics, the traditional artificial leather has a blocking effect on light and therefore cannot let light pass through, such that holes have to be punched in the surface for better interior transmittance. This has the results that, the cost of vehicle design is increased, and the mechanical properties of the product are reduced in the punching process, affecting the service life and application scope of the product.
Summary of the Invention Based on the above present situation, the main aim of the invention is to provide a kind of light-transparent artificial leather and a preparation method therefor, and an automotive interior, to solve the existing problem of artificial leather.
To achieve the above aim, the invention adopts the following technical scheme:
In a first aspect, the invention is a method for producing (preparation method) light-transparent artificial leather, and said preparation method comprises the steps of:
S100: Mixing, stirring, grinding, filtering and defoaming primary raw materials, including toner with a particle size of 0.5-10nm, polymer powder and a plasticizer, to produce a light-transparent pigment; mixing the light-transparent pigment with secondary raw materials, ;mixture, and stirring, grinding, filtering and defoaming said mixture to obtain a light-transparent epidermal layer material S200: Mixing a base fabric, glue and a support layer material with the aforesaid light-transparent epidermal layer material and making them into a semi-finished artificial leather product which comprises a light-transparent epidermal layer, a support layer, a glue layer and a base fabric, which are arranged in the appropriate order; and S300: Applying a surface treating agent on the surface of the light-transparent epidermal layer to produce a light-transparent artificial leather.
Wherein, in S100, the particle size of the toner in the light-transparent epidermal layer material is set to 05-10nm, e.g.., any of 0.5nm, mm, 1.5nm, 2nm, 2.5nm, 3nm, 3.5nm, 4nm, 4.5nm, 5nm, 5.5nm, 6nm, 6.5nm, 7nm, 7.5nm, 8nm, 8.5nm, 9nm, 9.5nm and lOnm.
The main reason for the poor transmittance of artificial leather is that the epidermal layer is a colored layer and has a great blocking effect on light, but if the dosage of the pigment is reduced, the color covering effect will be very poor. In embodiments of the invention, the toner in the light-transparent epidermal layer material is a toner having a Nano-particle size, which has a lower blocking effect on light, and can ensure ideal transmittance (of light) of the prepared artificial leather even if a large quantity of toner has to be used for a good color covering effect.
In the preparation process of a conventional prior art epidermal layer material, normally, various types of powder are directly mixed together and stirred. Since the toner utilized in the invention is Nano-sized, and therefore much tinier than other powders, uneven dispersion will be caused if it is mixed with other powders. In embodiments of the invention, the toner is made into a light-transparent pigment material first, and then the light-transparent pigment material is mixed with polymer powder, a plasticizer, a stabilizer and an inorganic additive to produce a

Wherein, in S100, the particle size of the toner in the light-transparent epidermal layer material is set to 05-10nm, e.g.., any of 0.5nm, mm, 1.5nm, 2nm, 2.5nm, 3nm, 3.5nm, 4nm, 4.5nm, 5nm, 5.5nm, 6nm, 6.5nm, 7nm, 7.5nm, 8nm, 8.5nm, 9nm, 9.5nm and lOnm.
The main reason for the poor transmittance of artificial leather is that the epidermal layer is a colored layer and has a great blocking effect on light, but if the dosage of the pigment is reduced, the color covering effect will be very poor. In embodiments of the invention, the toner in the light-transparent epidermal layer material is a toner having a Nano-particle size, which has a lower blocking effect on light, and can ensure ideal transmittance (of light) of the prepared artificial leather even if a large quantity of toner has to be used for a good color covering effect.
In the preparation process of a conventional prior art epidermal layer material, normally, various types of powder are directly mixed together and stirred. Since the toner utilized in the invention is Nano-sized, and therefore much tinier than other powders, uneven dispersion will be caused if it is mixed with other powders. In embodiments of the invention, the toner is made into a light-transparent pigment material first, and then the light-transparent pigment material is mixed with polymer powder, a plasticizer, a stabilizer and an inorganic additive to produce a
2 light-transparent epidermal layer material so as to greatly enhance the dispersible uniformity of the toner. In addition, the toner can be mixed with the polymer powder and plasticizer to form a light-transparent pigment material so as to greatly enhance the degree of fusion between the light-transparent pigment material and other powders. A grinding process is added to the preparation process of the light-transparent pigment material so that the toner can be mixed evenly with other powders to prevent agglomeration.
Preferably, the mass ratio of each element in the primary raw materials is as follows:
70-100 portions of toner, for example, 70, 75, 80, 85, 90, 95 or 100 portions;
70-100 portions of polymer powder, for example, 70, 75, 80, 85, 90, 95 or 100 portions; 70-100 portions of plasticizer, for example, 70, 75, 80, 85, 90, 95 or 100 portions.
In the light-transparent pigment material, the content of the toner cannot be too high or too low, because excessively high content affects transmittance of the artificial leather while excessively low content affects the color covering effect, so preferably, the mass ratio of the toner in the light-transparent pigment material is set to approximately 37%-40%.
In a preferred embodiment of the invention, in the light-transparent pigment material, the toner comprises organic toner and/or inorganic toner; the organic toner is a kind of permanent red, scarlet, everbright red, everbright fast red, Lithol scarlet/magenta/dark red/ruby/purplish red, lake red, rubber scarlet, lightfast pink lake, cherry-red, quinacridone red, permanent pink, permanent ruby, permanent orange, permanent Jaffa orange, everbright fast yellow, benzidine yellow, permanent yellow, pigment fast rose red lake, pale purple, quinacridone violet, phthalocyanine green or peacock blue lake toner; the inorganic toner is a kind of iron oxide pigment (red, yellow, green, black, orange, gray or brown), or a kind of chrome yellow toner, such as molybdate red, strontium yellow, lemon chrome yellow, medium chrome yellow, deep chrome yellow or zinc chrome yellow toner, or a kind of iron blue, ultramarine blue, chrome oxide green, pigment green or carbon black toner;

In the light-transparent pigment material, the content of the toner cannot be too high or too low, because excessively high content affects transmittance of the artificial leather while excessively low content affects the color covering effect, so preferably, the mass ratio of the toner in the light-transparent pigment material is set to approximately 37%-40%.

S100: Mixing, stirring, grinding, filtering and defoaming primary raw materials, including toner with a particle size of 0.5-10nm, polymer powder and a plasticizer, to produce a light-transparent pigment; mixing the light-transparent pigment with secondary raw materials, including polymer powder, a plasticizer, a stabilizer and an inorganic additive to produce a mixture, and stirring, grinding, filtering and defoaming said mixture to obtain a light-transparent epidermal layer material;
S200: Mixing a base fabric, glue and a support layer material with the light-transparent epidermal layer material and making them into a semi-finished artificial leather product which comprises a light-transparent epidermal layer, a support layer, a glue layer and a base fabric, which are arranged in an appropriate order; and S300: Applying a surface treating agent on the surface of the light-transparent epidermal layer to produce a light-transparent artificial leather.
The support layer comprises virtually the same materials as the light-transparent epidermal layer, and the only difference therebetween is that there is toner incorporated in the support layer.
The support layer of conventional prior art artificial leather is a foaming structure. Because foaming affects the transmittance of artificial leather, in a preferred embodiment of the invention, the support layer is not processed by foaming technology or is merely processed by micro-foaming technology, and such micro-foaming ratio is less than or equal to 1.5. If the support layer does not undergo a foaming process, there will be no foaming agent in the raw materials of the support layer; if the support layer undergoes a foaming process, there will be a small amount of foaming agent in the raw materials of the support layer such that the foaming

In S200, each layer structure can be formed by a release paper coating method or a calendering method (both such methods are incorporated herein by reference). The glue therein may be transparent glue or glue layer slurry made from polymer powder, or some other type of glue. In an embodiment of the invention, wherein transparent glue is used, if the release paper coating method is adopted (the raw material is slurry), the preparation process comprises the following steps of:
applying light-transparent epidermal layer slurry on to release paper to form a light-transparent epidermal layer;
applying support layer slurry on the light-transparent epidermal layer to form a support layer;
applying transparent glue on the support layer and cladding it with a base fabric;
separating each layer formed from the release paper, and then proceeding to S300 to produce a light-transparent artificial leather.
In an embodiment of the invention wherein the calendering method is adopted (the raw material is powder), the preparation method of the invention comprises the following steps of:
calendering the support layer powder to form a support layer;
calendering the light-transparent epidermal layer powder on the support layer to form a light-transparent epidermal layer;
applying transparent glue on the support layer and cladding it with a base fabric; and processing each layer formed in accordance with S300 to produce a light-transparent artificial leather.
The surface treating agent comprises water-borne polyurethane (WPU) and water-based color paste. Owing to the low thickness of the surface treating agent layer, which therefore has little impact on transmittance, to save costs, a kind of toner with a regular particle size, such as a particle size of 1-5um, is can be added to the water-based color paste. In addition, the surface treating agent layer may be processed by an embossing technology (which is incorporated herein

In an embodiment of the invention, wherein the raw material of glue is a type of glue layer slurry, the glue layer material also forms a glue layer and is affixed to the support layer, while the other side of the glue layer is covered with a base fabric. The base fabric can be a knitted fabric, non-woven fabric, three-dimensional spaced fabric or light-transparent polyurethane foam substrate. Similarly, in S200, each layer structure can be formed by a release paper coating method or a calendering method, for example, if the release paper coating method is applied (the raw material is slurry), the preparation method of the invention comprises the following steps of:
applying light-transparent epidermal layer slurry on to release paper to form a light-transparent epidermal layer;
applying support layer slurry on the light-transparent epidermal layer to form a support layer;
applying glue layer slurry on the support layer to form a glue layer; and pasting a base fabric to the glue layer, separating each layer formed from the release paper, and then proceeding to S300 to produce a light-transparent artificial leather.
In another embodiment of the invention, if the calendering method is applied (only the glue layer material is slurry, while the raw materials of other layers are powder), the preparation method of the invention comprises the following steps of:
applying glue layer slurry on to the base fabric to form a glue layer;
calendering the support layer powder on the glue layer to form a support layer;
calendering the light-transparent epidermal layer powder on the support layer to form a light-transparent epidermal layer; and then, processing each layer formed in accordance with S300 to produce light-transparent artificial leather.
The structure of the light-transparent artificial leather prepared by a preparation method of the invention disclosed herein is shown in FIG. 2. Said light-transparent artificial leather comprises a surface treating agent layer 100, light-transparent epidermal layer 200, support layer 300, glue layer 400 and base fabric 500, which are arranged layer upon layer in an appropriate order.
For an item covered in the light-transparent artificial leather prepared by the preparation method disclosed herein, light may transmit through the light-entire transparent artificial leather.
However, in some application scenarios, it is necessary to present a pattern with decorative effects or an indication of functions on the surface of the light-transparent artificial leather. Based on this, in a preferred embodiment of the invention, the preparation method also comprises a step of forming a light-shielding layer, comprising a step of light-shielding layer formation, whereby the light-shielding layer is formed between the light-transparent epidermal layer and the support layer, and the light-shielding layer is a hollowed-out structure to form a pattern.
In this manner, the light-transparent artificial leather, when the light is off, will look normal, but when the light is on, there will be a visible pattern on the surface of the light-transparent artificial leather. Such an embodiment of the invention has several benefits, for example, there is no requirement for the light source to have any particular shape, i.e., there is no need to shape the light source in a specific manner. As an additional benefit, after the light-shielding layer is incorporated in the light-transparent artificial leather, the light-shielding layer will be very close to the surface of the light-transparent artificial leather, and there will be virtually no light scattering caused, thus the pattern is made quite clearly discernible and visible. The clarity of the pattern won't be affected even if the light-transparent artificial leather is affixed to a three-dimensional spacer fabric to form a composite structure. As a further additional benefit, the light-shielding layer can be prevented from making contact with other structures, with the result that the light-shielding layer may be well protected. Compared with a method of providing a light-shielding layer on the outer side of the light-transparent artificial leather, this arrangement method may effectively protect the light-shielding layer from falling off or being destroyed by other structures bonded to it.
In embodiments of the present invention, the light-shielding layer can be glued to the light-transparent epidermal layer and support layer after preparation thereof In order that the light-shielding should be better glued to the material layer, in a preferred embodiment of the invention, the light-shielding can be printed on the surface of the light-transparent epidermal layer or support layer. For example, in an embodiment of the invention wherein the release paper coating method is applied, the light-shielding can be printed on the surface of the light-transparent epidermal layer and then coated with support layer slurry to form a support layer. In an embodiment of the invention wherein the calendering method is applied, the light-shielding can be printed on the surface of the support layer and then coated with light-transparent epidermal layer powder to form a light-transparent epidermal layer by calendering. The printing method may be one of many kinds of printing methods such as one or more of the following: UV printing, gravure printing, heat transfer process and screen printing. The printing method may comprise a simple process, such as one or more of multi-color gradient and true-color displaying. UV
printing is particularly suitable for the printing of a light-shielding layer comprising a light-transmitting structure.
The light-transparent artificial leather prepared by the preparation method of the invention can be used as part of or incorporated within an automotive interior.
