Abstract

The invention discloses a colorful composite floor board, relating to macromolecular polymer decoration material. The floor board is composed of a bottom layer, a pattern layer and a wear layer arranged on the upper surface; wherein the bottom layer is PVC white slice, the pattern layer is composed of two printing slices printed with patterns and a transparent septum arranged between the two printing slices, and the wear layer is a transparent PVC membrane with colorless UV coating on the outside surface. The printing slice is composed of a transparent PVC slice and a pearly-luster coating, and the pearly-luster coating is printed with a pattern. The pattern is combined stripe formed by sequential arrangement of wavy lines formed by connecting of two arcs in different chord lengths, and the distance of adjacent wavy lines is in periodic variation. The floor board is good in abrasive resistance and long in service life, the pattern is stereoscopic, innervation can be obtained when observing in different angles, decoration effect is good, application is wide, and production cost is relatively low.

Description

technical field

[0001] The invention relates to a high molecular polymer decorative material, in particular to a polyvinyl chloride colorful composite floor. Background technique

[0002] PVC flooring is made by adding plasticizers, stabilizers, colorants and fillers to polymer polyvinyl chloride (PVC) resin, and is generally processed by molding process. In order to enhance the decorative effect, regular patterns are usually pasted or printed on the floor surface. After a period of use, the surface pattern and color will be worn away, and the decorative effect will not be achieved. Chinese patent 021090939 discloses a polyvinyl chloride wear-resistant flashing colorful floor. Inorganic wear-resistant materials and colorful PVC particles are added to the existing floor substrate, which can significantly improve the wear resistance and decoration of the floor. Due to the lack of compatibility between the inorganic wear-resistant material and the PVC matrix, the binding force...

Examples

example 1

[0012] Example 1: See the attached figure, the colorful composite floor is composed of a bottom layer, a pattern layer and a wear-resistant layer. The bottom layer is a white polyvinyl chloride sheet 1 with a thickness of 0.6mm. The white sheet is formed by calendering 97% (mass percentage, the same below) of PVC and 3% of titanium white pigment. The pattern layer is composed of two printed sheets 2 and a transparent spacer 3 sandwiched therebetween, and the transparent spacer 3 is composed of three layers of PVC transparent sheets with a thickness of 0.5 mm. The wear-resistant layer is a PVC transparent film 4 with a colorless UV paint layer on the outer surface, and the thickness is 0.3mm. Each layer (film) in the above structure is hot-pressed into one body by conventional technology on a general-purpose hot press.

[0013] The printing sheet is coated with pearlescent oil on a 0.07mm thick PVC transparent sheet, and then a specific pattern is printed on the pearlescent oi...
