A spray painting poster cloth

Abstract

The invention relates to the technical field of poster paper and particularly relates to a spray painting poster cloth. The poster cloth comprises a base cloth, coatings at two sides of the base cloth, and PVC films at the sides not connected to the base cloth of the coatings. The coatings comprise 30-60 parts by mass of polyacrylate resin, 10-15 parts by mass of silica, 1-4 parts by mass of a whitening agent, 20-30 parts by mass of titanium white pulp, 3-8 parts by mass of a lubricating agent, 8-15 parts by mass of a plasticizer, 1-3 parts by mass of a dispersant, 20-40 parts by mass of ethanol and 10-20 parts by mass of ethyl acetate. Beneficial effects of the poster cloth are that the service lifetime is long, a production process is simple, bonding fastness between the base cloth and the PVC film is high, peel strength is high, and anti-fouling, waterproof and flame retardant properties and the like can be achieved by adding different additives.

Description

technical field [0001] The invention relates to the technical field of advertising paper, in particular to an inkjet advertising cloth. Background technique [0002] At present, the advertising cloth or digital printing materials on the market are all printed materials covered with PVC raw materials. The full name of PVC is Polyvinylchlorid. This material has the advantages of flame retardancy and high chemical resistance; the combination with the printing industry makes PVC advertising cloth widely used in the advertising industry, but the commonly used PVC advertising cloth has always had the following technical problems: 1. PVC advertising cloth has poor softness and sag, is not easy to fold, and is prone to technical problems such as creases, curling, and breakage; 2. PVC advertising cloth requires a lot of plastic additives due to the material, which leads to the environmental protection performance of advertising cloth; 3. The process is complicated, and the coating m...

Problems solved by technology

This material has the advantages of flame retardancy and high chemical resistance; the combination with the printing industry makes PVC advertising cloth widely used in the advertising industry, but the commonly used PVC advertising cloth has always had the following technical problems: 1. PVC advertising cloth has poor softness and sag, is not easy to fold, and is prone to technical problems such as creases, curling, and breakage; 2. PVC advertising cloth requires a lot of plastic additives due to the material, which leads to the environmental protection performance of advertising cloth; 3. 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 dipping knife scraping method is complicated and energy consumption is high; 4. The weight of the product High, high cost of raw materials, because the base cloth is dipped in slurry first, and then the coating on the surface of the base cloth is scraped, so the coating amount is large, resulting in a high weight of the finished product and high cost of raw materials, which is not conducive to Transportation and use; 5. It is difficult to accurately control the product quality. 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. , affect the appearance of the product and the effect of inkjet printing; 6. Only one-sided printing can be carried out, because light-colored materials do not have enough shielding effect on the light, resulting in mutual influence on the pictures after double-sided printing. If shading materials such as carbon black are added to the slurry, It will also affect the curing effect of the slurry and reduce the peel strength between the base fabric and the PVC film
