Problems solved by technology

[0004] The purpose of the present invention is to provide a production process of multi-layer co-extruded PP wood-grain and stone-grain printed decorative film to solve the problem that the surface hardness of PVC proposed in the above-mentioned background technology is not enough, PVC cannot be degraded, and bad gas is produced during combustion, which is harmful to the human body. Harmful, and at the same time, the printed PP surface ink layer has poor scratch resistance

Embodiment 1

[0038] Feeding: The high-filled environmentally friendly calcium carbonate material and two sets of PP materials are transported to three extruders as needed through the feeding system, and the PP film with printed patterns is installed on the laminating mechanism; extrusion: PP The materials and high-filled environmentally friendly calcium carbonate materials are subjected to high temperature plasticization and melting after entering the extruder, and are uniformly discharged from the extruder through the extrusion of the output device; compression mold: PP materials and high-filled environmentally friendly calcium carbonate materials are extruded After the machine is discharged, it flows through the T-shaped structure forming die, and the molten PP is extruded by the T-shaped structure forming die into a film-like fluid; layering: PP material and high-filled environmentally friendly calcium carbonate material pass through the layering of the splitter and follow Arrange into th...

Embodiment 2

[0040] In the first embodiment, the following steps are added:

[0041] In step 1, the PP material and the high-filled environmentally friendly calcium carbonate material need to be fully dried and crushed before loading. The PP film can be rolled into a tube. The moisture in the material can be degraded during the heating process, and air bubbles will also be generated. The quality of the product is affected, and the moisture can be removed by drying to avoid the impact on the product quality; the PP film is printed with wood grain and stone print decorative patterns in advance as needed, and the pattern is printed in reverse printing mode. The pattern printing mode can facilitate the ink layer Carry out isolation protection to avoid scratches during use.

[0042] Feeding: The high-filled environmentally friendly calcium carbonate material and two sets of PP materials are transported to three extruders as needed through the feeding system, and the PP film with printed patterns is ...

Embodiment 3

[0044] In the second embodiment, the following steps are added:

[0045] In step 2, in step 2, the PP material and the high-filled environmentally friendly calcium carbonate material need to be filtered through a filter after being extruded by the extruder to remove impurities and impurities in the PP material and the high-filled environmentally friendly calcium carbonate material The melted material is filtered, and the PP wood-grain stone pattern and printed decorative film are made by extrusion casting method, and the multi-layer co-extrusion method is adopted to meet the performance while reducing the cost, avoiding impurities and unmelted materials from affecting product quality.

[0046] Feeding: The high-filled environmentally friendly calcium carbonate material and two sets of PP materials are transported to three extruders as needed through the feeding system, and the PP film with printed patterns is installed on the laminating mechanism; extrusion: PP The materials and hi...

Abstract

The invention discloses a production process of a multilayer co-extrusion PP wood-grain and stone-grain printed decorative film, wherein the production process comprises the following steps: feeding:respectively conveying a high-filling environment-friendly calcium carbonate material and two groups of PP materials into three extruders through a feeding system according to requirements, and mounting a PP film printed with patterns on a laminating mechanism; extrusion: plasticizing and melting the PP material and the high-filling environment-friendly calcium carbonate material at high temperature after entering the extruder, and uniformly discharging from the extruder through extrusion of an output device. Through the production process of the multilayer co-extrusion PP wood-grain and stone-grain printed decorative film, the extrusion casting method is adopted; the problems that the surface hardness of PVC is not enough, PVC cannot be degraded, bad gas is generated during combustion andharmful to the human body, and meanwhile, the scratch resistance of a printed PP surface ink layer is poor are solved; the decorative film has the advantages that the surface hardness is excellent, the scratch resistance is quite high, an ink printing layer cannot be scratched even if the decorative film is scratched, and the pattern durability is prolonged.

Description

Technical field [0001] The invention relates to the technical field of wallpaper production technology, in particular to a production process of a multilayer co-extruded PP wood grain stone grain printing decorative film. Background technique [0002] Wallpaper, also known as wallpaper, is a kind of interior decoration material used for pasting walls.
