Description

一种装饰材料及其制备方法Decorative material and preparation method thereof 技术领域Technical field

背景技术Background technique
在现有的装饰材料市场上，随着消费者对环保意识的增强，对材料的要求也越来越严格。传统的聚氯乙烯(PVC)薄膜材料环保性能较差，因此越来越多地采用聚丙烯(PP)薄膜作为装饰材料。In the existing decorative materials market, as consumers' awareness of environmental protection increases, the requirements for materials are becoming stricter. Traditional polyvinyl chloride (PVC) film materials have poor environmental performance, so polypropylene (PP) films are increasingly used as decorative materials.
并且由于装置材料尤其是用于家居装饰的材料，与消费者接触较多，甚至是皮肤接触机会也较多，如门板、衣柜和橱柜等，导致消费者对产品表面触感要求也逐渐提高，表面具有丝滑触感的产品深受追捧。但是市面上很多PP装饰膜塑料感比较强，触感也不够光滑。And because the device materials, especially the materials used for home decoration, have more contact with consumers and even more skin contact opportunities, such as door panels, wardrobes and cabinets, etc., consumers have gradually increased the tactile requirements of the product surface. Products with silky touch are highly sought after. However, many PP decorative films on the market have a strong plastic feel and are not smooth enough to touch.

在生产中，可通过压纹处理的方式可以调整表面的粗糙度及光泽度。压纹处理是通过花辊(压纹辊)实现的，不同纹路的花辊的粗糙度及光泽度可分开设置的，如某条花辊是较粗糙且较低光泽，而另一条花辊则是较不粗糙且较低光泽，再另一条是粗糙且较高光泽等(即，可以有不同的组合)，通过花辊纹理的设计选择，以达成对粗糙度及光泽的设计预期。In production, the surface roughness and gloss can be adjusted by embossing. The embossing process is realized by an embossing roller (embossing roller). The roughness and gloss of the embossing rollers with different textures can be set separately. For example, one embossing roller is rougher and has lower gloss, while the other embossing roller It is less rough and lower gloss, and another is rough and higher gloss, etc. (that is, there can be different combinations), through the design selection of the texture of the flower roller, to achieve the design expectations of roughness and gloss.
除同上压纹处理来获得3个物理量参数的范围外，但是涂层材料的选择也非常重要。涂层材料也可以说影响或是说控制这3个物理量，不同的涂层材料干燥后它们的表面粗糙度和光泽度是完全不一样的(特别是光泽度，更多是受表处剂影响)，这些差异并不会被压花完全消除，因此所述中间层由第二聚氨酯涂料形成；所述涂层由聚氨酯涂料形成；所述聚氨酯涂料与第二聚氨酯涂料均同上所述，在此不再赘述。In addition to the same embossing process to obtain the range of three physical parameters, but the choice of coating material is also very important. The coating material can also be said to affect or control these three physical quantities. The surface roughness and glossiness of different coating materials after drying are completely different (especially the glossiness is more affected by the surface treatment agent ), These differences will not be completely eliminated by embossing, so the intermediate layer is formed by the second polyurethane coating; the coating is formed by the polyurethane coating; the polyurethane coating and the second polyurethane coating are the same as described above, here No longer.
为了进一步说明本发明，以下结合实施例对本发明提供的一种装饰材料及其制备方法进行详细描述。In order to further illustrate the present invention, a decorative material provided by the present invention and a preparation method thereof will be described in detail below in conjunction with embodiments.
以下实施例中所用的试剂均为市售。The reagents used in the following examples are all commercially available.
