Spray-painting advertisement cloth and production process thereof

Abstract

The invention relates to an advertisement-displaying and decorative material carrier, and especially relates to spray-painting advertisement cloth and a production process thereof. The spray-painting advertisement cloth comprises base cloth, coatings at the two sides, and PVC films at two sides of the coatings; the production process comprises the following steps: 1) unreeling a PVC light-color film, coating the PVC light-color film with a polymer coating by an anilox roller; 2) attaching the PVC light-color film to base cloth; 3) treating a PVC dark-color film according to the step 1), coating the polymer coating, attaching the PVC dark color film to the other side of the base cloth; 4) preheating another PVC light-color film, and attaching to the PVC dark-color film; 5) reeling and packaging. The production process is concise, and the process flow is complete; the coating is thin and light in mass, which greatly improves the production efficiency and raw material utilization rate, and saves cost; the coating is flat and uniform; the product has good spray-painting performance, excellent ink absorption performance, high color rendition degree, and wide applications.

Description

technical field [0001] The invention relates to an advertising display and decorative material carrier, in particular to an inkjet advertising cloth and a production process thereof. Background technique [0002] At present, inkjet advertising cloth is basically made of industrial polyester base cloth after soaking in PVC slurry, knife scraping, drying, and pasting PVC white film on both sides. After scraping and leveling, it is dried, and the slurry is cured to form a coating, so that the base cloth is shaped and bonded to the PVC film. The spray-painted advertising cloth produced by this soaking knife scraping method has a smooth surface and a good spray-painting effect, but there are generally the following problems: [0003] 1. The process is complicated, and the coating must be dried and cured, and the amount of coating is proportional to the time and energy spent on drying, so the process of dipping and scraping is complicated and the energy consumption is high; [0...

AI Technical Summary

Problems solved by technology

[0003] 1. The process is complicated, and the coating must be dried and cured, and the amount of coating is proportional to the time and energy spent on drying, so the process of dipping and scraping is complicated and the energy consumption is high;

[0004] 2. The weight of the product is high, and the cost of raw materials is high. Because the base fabric is soaked in pulp first, and then the coating on the surface of the base fabric is scraped, so the coating amount is large, resulting in a high weight of the finished product, and the consumption of raw materials High cost, not conducive to transportation and use;

[0005] 3. The quality of the product is difficult to control accurately. In the production process, it is inevitable to encounter sudden changes in speed and uneven tension. At this time, knife marks will be formed on the coating surface or the coating amount will be uneven, which will affect the appearance of the product. and inkjet effects;

[0006] 4. It can only be printed on one side, because light-colored materials do not have enough shielding effect on the light, resulting in the mutual influence of the pictures after double-sided printing. If shading materials such as carbon black are added to the slurry, it will affect the curing effect of the slurry. Reduce the peel strength between base fabric and PVC film
