透光性人造革及其制备方法、汽车内饰Translucent artificial leather, preparation method thereof, and automobile interior decoration 技术领域Technical field
本发明涉及人造革技术领域，具体涉及一种透光性人造革及其制备方法、汽车内饰。The invention relates to the technical field of artificial leather, in particular to a translucent artificial leather, a preparation method thereof, and automobile interior decoration.
背景技术Background technique
人造革是一种外观、手感似皮革并可代替其使用的塑料制品，具有柔软、耐磨等特点，可广泛用于箱包、汽车内饰等。Artificial leather is a kind of plastic product that looks and feels like leather and can replace it. It has the characteristics of softness and wear resistance, and can be widely used in luggage, car interiors, etc.
随着汽车内饰行业的发展，人们对车内氛围及人车互动的要求逐步提高。传统的人造革因其独特的材料特性对光线具有阻隔效应，并不具备透光性能，车内光学效果都是通过表面打孔来实现的，这不仅增加了整车设计的成本，且冲孔工艺会降低产品的力学性能，影响使用寿命以及产品的应用范围。With the development of the automotive interior industry, people's requirements for the atmosphere in the car and the interaction between people and cars are gradually increasing. Traditional artificial leather has a blocking effect on light due to its unique material characteristics, and does not have light transmission properties. The optical effects in the car are all realized by surface punching, which not only increases the cost of the vehicle design, but also the punching process It will reduce the mechanical properties of the product, affect the service life and the application range of the product.
发明内容Summary of the invention
基于上述现状，本发明的主要目的在于提供一种透光性人造革及其制备方法、汽车内饰，以解决现有人造革存在的上述问题。Based on the above-mentioned current situation, the main purpose of the present invention is to provide a translucent artificial leather, a preparation method thereof, and automobile interior decoration, so as to solve the above-mentioned problems existing in the existing artificial leather.
为实现上述目的，本发明采用的技术方案如下：In order to achieve the above objectives, the technical solutions adopted by the present invention are as follows:
本发明的第一方面提供了一种透光性人造革的制备方法，所述制备方法包括步骤：The first aspect of the present invention provides a preparation method of translucent artificial leather, the preparation method comprising the steps:
S100、将含有粒径为0.5～10nm的色粉以及聚合物粉、增塑剂的初级原料进行混合、搅拌、研磨、过滤、脱泡，得到透光颜料原料；将所述透光颜料原料与含有聚合物粉、增塑剂、稳定剂、无机添加剂的次级原料进行混合、搅拌、过滤、脱泡，得到透光表皮层原料；S100. Mix, stir, grind, filter, and defoam primary raw materials containing toner with a particle size of 0.5-10 nm, polymer powder, and plasticizer to obtain a light-transmitting pigment raw material; combining the light-transmitting pigment raw material with The secondary raw materials containing polymer powder, plasticizers, stabilizers, and inorganic additives are mixed, stirred, filtered, and defoamed to obtain the light-transmitting skin layer raw materials;
S200、利用基布、胶水原料、支撑层原料和所述透光表皮层原料进行制备，得到由透光表皮层、支撑层、胶水层和基布依次排布形成的人造革半成品；S200. Prepare a base fabric, glue raw materials, support layer raw materials, and the light-transmitting skin layer raw materials to obtain an artificial leather semi-finished product formed by sequentially arranging the light-transmitting skin layer, the supporting layer, the glue layer and the base cloth;
S300、在所述透光表皮层的表面涂覆表面处理剂，得到所述透光性人造革；S300. Coating a surface treatment agent on the surface of the light-transmitting skin layer to obtain the light-transmitting artificial leather;
其中，所述步骤S100中，所述透光表皮层原料中的色粉的粒径为0.5～10nm，例如为0.5nm、1nm、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、10nm。Wherein, in the step S100, the particle size of the toner in the light-transmitting skin layer raw material is 0.5-10nm, for example, 0.5nm, 1nm, 1.5nm, 2nm, 2.5nm, 3nm, 3.5nm, 4nm, 4.5. nm, 5nm, 5.5nm, 6nm, 6.5nm, 7nm, 7.5nm, 8nm, 8.5nm, 9nm, 9.5nm, 10nm.
人造革的透光性差的主要原因是由于表皮层是带颜色层，对光线具有很大的阻碍作用，而若减少颜料的用量，则颜色的遮盖性就会很差。本申请中，透光表皮层原料中的色粉采用纳米级粒径的色粉，从而降低色粉对光线的阻碍，即使为了保证颜色遮盖性而使用的色粉量较大，也能够保证制备出的人造革具备一定的透光性。The main reason for the poor light transmittance of artificial leather is that the skin layer is a colored layer, which has a great obstructive effect on light. If the amount of pigments is reduced, the color coverage will be poor. In this application, the toner in the raw material of the light-transmitting skin layer adopts nano-sized toner, thereby reducing the obstacle of the toner to light. Even if a large amount of toner is used to ensure the color opacity, the preparation can be guaranteed. The artificial leather produced has a certain degree of light transmittance.
在常规的表皮层原料的制备过程中，通常是将各种粉料直接混合搅拌在一起，由于色粉的粒径是纳米级的，非常微小，与其他粉料的粒径均不在一个数量级，若直接将其与其他粉料混合会非常容易造成色粉的分散不均，而本申请中，首先将色粉形成透光颜料原料，然后再将透光颜料原料与聚合物粉、增塑剂、稳定剂、无机添加剂进行混合得到透光表皮层原料，能够大大提高色粉的分散均匀性，另外，将色粉与聚合物粉和增塑剂混合形成透光颜料原料，能够大大提高透光颜料原料与其他粉料的融合度。在制备透光颜料原料时添加了研磨工艺，使得色粉和其他粉料混合均匀，防止出现团聚。In the preparation process of the conventional skin layer raw materials, various powders are usually directly mixed and stirred together. Because the particle size of the toner is nano-sized, very small, and the particle size of other powders is not in the same order of magnitude. If it is directly mixed with other powders, it is very easy to cause uneven dispersion of the toner. In this application, the toner is first formed into a light-transmitting pigment raw material, and then the light-transmitting pigment raw material is combined with polymer powder and plasticizer , Stabilizers and inorganic additives are mixed to obtain the light-transmitting skin layer raw material, which can greatly improve the dispersion uniformity of the toner. In addition, mixing the toner, polymer powder and plasticizer to form a light-transmitting pigment raw material can greatly improve the light transmission The degree of fusion of pigment raw materials with other powders. A grinding process is added when preparing the light-transmitting pigment raw materials to make the toner and other powders mix uniformly and prevent agglomeration.

Mix, stir, grind, filter, and defoam primary raw materials containing toner with a particle size of 0.5-10 nm, polymer powder, and plasticizer to obtain a light-transmitting pigment raw material; combining the light-transmitting pigment raw material with The secondary raw materials containing polymer powder, plasticizers, stabilizers, and inorganic additives are mixed, stirred, filtered, and defoamed to obtain the light-transmitting skin layer raw materials;
S200、利用基布、胶水原料、支撑层原料和所述透光表皮层原料进行制备，得到由透光表皮层、支撑层、胶水层和基布依次排布形成的人造革半成品；S200. Prepare a base fabric, glue raw materials, support layer raw materials, and the light-transmitting skin layer raw materials to obtain an artificial leather semi-finished product formed by sequentially arranging the light-transmitting skin layer, the supporting layer, the glue layer and the base cloth;
S300、在所述透光表皮层的表面涂覆表面处理剂，得到所述透光性人造革。S300: Coating a surface treatment agent on the surface of the light-transmitting skin layer to obtain the light-transmitting artificial leather.
支撑层原料的配方与透光表皮层类似，区别在于支撑层中不添加色粉。通常的人造革的支撑层设置为发泡结构，由于发泡会影响人造革的透光性，因此，优选地，支撑层不进行发泡工艺或进行微发泡工艺，微发泡工艺的发泡倍率小于或等于1.5，当支撑层不进行发泡工艺时，支撑层原料中不含发泡剂，当支撑层进行微发泡工艺时，支撑层原料中含少量发泡剂以使得发泡倍率小于或等于1.5。步骤S200中，可以采用离型纸涂覆法、压延法等方法形成各层结构。其中的胶水原料可以为透明胶水，也可以为聚合物粉等材料形成的胶水层浆料，在胶水原料为透明胶水的实施例中，采用离型纸涂覆法(原料为浆料)，执行如下步骤：The formulation of the raw material of the support layer is similar to that of the light-transmitting skin layer, the difference is that no toner is added to the support layer. The support layer of the usual artificial leather is set in a foamed structure. Since foaming will affect the light transmittance of the artificial leather, it is preferable that the support layer is not subjected to a foaming process or a micro-foaming process. The foaming ratio of the micro-foaming process is Less than or equal to 1.5. When the support layer is not subjected to the foaming process, the raw material of the support layer does not contain foaming agent. When the support layer is subjected to the micro-foaming process, the raw material of the support layer contains a small amount of foaming agent to make the foaming ratio less than Or equal to 1.5. In step S200, a release paper coating method, a calendering method, and other methods may be used to form each layer structure. The glue raw material can be transparent glue or a glue layer slurry formed by polymer powder and other materials. In the embodiment where the glue raw material is transparent glue, the release paper coating method (the raw material is slurry) is used. The following steps:
在离型纸上涂覆透光表皮层浆料形成透光表皮层；Coat the light-transmitting skin layer slurry on the release paper to form the light-transmitting skin layer;
在透光表皮层上涂覆支撑层浆料形成支撑层；Coating the support layer slurry on the light-transmitting skin layer to form a support layer;
在支撑层上涂覆透明胶水并贴覆基布；Coat transparent glue on the support layer and paste the base cloth;
将形成的各层与离型纸剥离，Peel the formed layers from the release paper,
再进行步骤S300得到透光性人造革。Step S300 is then performed to obtain translucent artificial leather.
采用压延法时(原料为粉料)，执行如下步骤：When using the calendering method (raw material is powder), perform the following steps:
将支撑层粉料压延形成支撑层；Calender the support layer powder to form the support layer;
将透光表皮层粉料在支撑层上压延形成透光表皮层；Calender the light-transmitting skin layer powder on the support layer to form a light-transmitting skin layer;
在支撑层上涂覆透明胶水并贴覆基布；Coat transparent glue on the support layer and paste the base cloth;
将形成的各层进行步骤S300得到透光性人造革。Step S300 is performed on the formed layers to obtain translucent artificial leather.
表面处理剂采用水性聚氨酯材料并添加水性色浆，由于表面处理剂形成的表面处理剂层厚度较薄，对透光性的影响不大，为节约成本，水性色浆中的色粉采用常规粒径色粉即可，例如粒径为1～5um，另外，还可对表面处理剂层进行压花处理。The surface treatment agent is made of water-based polyurethane material and water-based color paste is added. Because the thickness of the surface treatment agent layer formed by the surface treatment agent is relatively thin, it has little effect on the light transmittance. In order to save costs, the toner in the water-based color paste adopts conventional particles. The toner may have a diameter of 1 to 5um, for example, and the surface treatment agent layer may be embossed.
在胶水原料为胶水层浆料的实施例中，还利用胶水层原料形成胶水层贴附于支撑层，胶水层的另一面贴合于基布，基布可以为针织布、无纺布，也可以为三维间隔型织物、透光聚氨酯海绵等，类似地，步骤S200中，可以采用离型纸涂覆法、压延法等方法形成各层结构，例如，采用离型纸涂覆法时(原料为浆料)，执行如下步骤：In the embodiment where the glue material is the glue layer slurry, the glue layer is also used to form a glue layer to be attached to the support layer, and the other side of the glue layer is attached to the base fabric. The base fabric can be knitted fabric, non-woven fabric, or It can be a three-dimensional spacer fabric, a light-transmitting polyurethane sponge, etc., similarly, in step S200, a release paper coating method, a calendering method, etc. can be used to form each layer structure, for example, when a release paper coating method is used (raw material Is slurry), perform the following steps:
在离型纸上涂覆透光表皮层浆料形成透光表皮层；Coat the light-transmitting skin layer slurry on the release paper to form the light-transmitting skin layer;
在透光表皮层上涂覆支撑层浆料形成支撑层；Coating the support layer slurry on the light-transmitting skin layer to form a support layer;
在支撑层上涂覆胶水层浆料形成胶水层；Coating the glue layer slurry on the support layer to form a glue layer;
将基布粘接于胶水层，将形成的各层与离型纸剥离，再进行步骤S300得到透光性人造革。The base cloth is adhered to the glue layer, the formed layers are peeled off from the release paper, and step S300 is performed to obtain the translucent artificial leather.
再例如，采用压延法时(除胶水层原料为浆料外，其他为粉料)，执行如下步骤：For another example, when the calendering method is used (except for the glue layer raw material is slurry, the others are powder), perform the following steps:
将胶水层浆料涂覆于基布形成胶水层；Coating the glue layer slurry on the base cloth to form a glue layer;
将支撑层粉料在胶水层上压延形成支撑层；Calender the support layer powder on the glue layer to form a support layer;
将透光表皮层粉料在支撑层上压延形成透光表皮层，将形成的各层进行步骤S300得到透光性人造革。The light-transmitting skin layer powder is rolled on the support layer to form a light-transmitting skin layer, and the formed layers are subjected to step S300 to obtain light-transmitting artificial leather.
采用上述制备方法制备的透光性人造革的结构如图2所示，包括依次层叠设置的表面处理剂层100、透光表皮层200、支撑层300、胶水层400和基布500。The structure of the light-transmitting artificial leather prepared by the above-mentioned preparation method is shown in FIG.
将上述制备方法制备的透光性人造革覆盖在光源上可实现透光性人造革的整体透光效果。而在某些应用场景中，需要在透光性人造革的表面呈现出具有装饰效果或指示功能的图案，基于此，在一个优选的实施例中，制备方法还包括遮光层形成步骤，在遮光层形成步骤中，将遮光层形成于透光表皮层和支撑层之间，其中，形成的遮光层上具有镂空或透光结构以形成图案，如此，将该透光性人造革覆盖在光源后，当光源关灭时，透光性人造革呈现常规的人造革外观，而当光源点亮时，在透光性人造革的表面呈现出图案。这样设置，一方面对光源的形状无要求，无需将光源设置为特定造型，另外，将遮光层植于透光性人造革内，一方面使得遮光层距离透光性人造革的表面非常近，光线几乎不会发生散射，因此呈现的图案非常清晰，即使该透光性人造革贴附于三维间隔型织物形成复合结构，也不会影响呈现出的图案的清晰度，另一方面，能 够避免遮光层与其他结构接触，对遮光层形成很好的保护，相较于将遮光层设置在透光性人造革的外侧，能够有效避免遮光层的脱落以及与其他结构粘接时对遮光层的破坏。Covering the light-transmitting artificial leather prepared by the above preparation method on the light source can realize the overall light-transmitting effect of the light-transmitting artificial leather. In some application scenarios, it is necessary to present a pattern with a decorative effect or indicating function on the surface of the light-transmitting artificial leather. Based on this, in a preferred embodiment, the preparation method further includes a light-shielding layer forming step. In the forming step, the light-shielding layer is formed between the light-transmitting skin layer and the support layer, wherein the light-shielding layer is formed with a hollow or light-transmitting structure to form a pattern. In this way, the light-transmitting artificial leather is covered on the light source. When the light source is off, the light-transmitting artificial leather presents the appearance of conventional artificial leather, and when the light source is on, a pattern appears on the surface of the light-transmitting artificial leather. With this arrangement, on the one hand, there is no requirement for the shape of the light source, and there is no need to set the light source to a specific shape. In addition, the light-shielding layer is planted in the light-transmitting artificial leather. On the one hand, the light-shielding layer is very close to the surface of the light-transmitting artificial leather, and the light is almost No scattering occurs, so the pattern presented is very clear. Even if the translucent artificial leather is attached to the three-dimensional spacer fabric to form a composite structure, it will not affect the clarity of the presented pattern. On the other hand, it can avoid the light shielding layer and Contact with other structures provides good protection for the light-shielding layer. Compared with arranging the light-shielding layer on the outside of the light-transmitting artificial leather, it can effectively prevent the light-shielding layer from falling off and damage to the light-shielding layer when bonded with other structures.
遮光层可以是制备好后与透光性表皮层和支撑层贴合，为了提高遮光层与材料层的贴合度，优选地，遮光层通过印刷方式形成于透光表皮层或支撑层的表面，例如，当采用离型纸涂覆法时，遮光层印刷于透光表皮层的表面，然后在遮光层上涂覆支撑层浆料形成支撑层，而当采用压延法时，遮光层印刷于支撑层的表面，然后将透光表皮层粉料在遮光层上压延形成透光表皮层。印刷方式例如为UV印刷、凹版印刷、热转印、丝网印刷等。UV印刷因其工艺简单、能够实现多色渐变和真彩显示效果等优点，尤其适于设有透光结构的遮光层的印刷。The light-shielding layer may be prepared and bonded to the light-transmitting skin layer and the support layer. In order to improve the adhesion between the light-shielding layer and the material layer, preferably, the light-shielding layer is formed on the surface of the light-transmitting skin layer or the support layer by printing. For example, when the release paper coating method is used, the light-shielding layer is printed on the surface of the light-transmitting skin layer, and then the supporting layer paste is coated on the light-shielding layer to form the supporting layer, and when the calendering method is used, the light-shielding layer is printed on On the surface of the support layer, the light-transmitting skin layer powder is then rolled on the light-shielding layer to form a light-transmitting skin layer. The printing method is, for example, UV printing, gravure printing, thermal transfer, screen printing, and the like. UV printing is especially suitable for printing with a light-shielding layer with a light-transmitting structure due to its simple process, multi-color gradation and true color display effects.
