Abstract

The invention belongs to the technical field of PVC board processing, and particularly relates to a decorative composite board and a production process thereof. Aiming at the problems of poor stability and processability of a PVC board during processing, the decorative composite board comprises a bottom board layer, a spray painting coating and a curing coating, the bottom plate layer comprises a high-density PVC plate solid section and a middle section which are formed by an extrusion process, the spray-painted coating is adhered to the upper surface of the middle section of the bottom plate layer, and the cured coating is pressed and adhered to the outer surface of the spray painting coating; and the PVC board is subjected to extrusion molding processing treatment through an extruder, the separability of a mouth mold is improved, and the heat stabilizer, the processing modifier, the impact modifier, the lubricant, the filler and the light stabilizer are added according to a certain proportion during PVC resin processing, so that the stability and processability of the PVC composite board during processing are improved, the processing mechanical load is reduced, the product is smooth, the plasticizing quality of the composite board is improved, the appearance of the composite board is changed, and the rigidity effect of the composite board is improved.

Description

technical field [0001] The invention relates to the technical field of PVC plate processing, in particular to a decorative composite plate and a production process thereof. Background technique [0002] The natural color of polyvinyl chloride (PVC) is light yellow translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. But lower than polypropylene, there will be whitening at the inflection point; decorative panels are one of the important raw materials for interior decoration and home decoration, and currently the panels in the decorative material market are mainly PVC panels. [0003] With the improvement of the quality of human life and the enhancement of environmental protection awareness, due to the poor therm...
