Problems solved by technology

While this operation meets the shading requirements, there are also many problems.
Adopt direct coating process and increase the amount of sizing, which requires higher energy consumption to dry the coating, and too thick coating is prone to cracking and surface blistering, and the final product feels hard and inelastic, which is not convenient for stretching. Exhibition, and the fastness is not good (the black layer is easy to scratch off)
The shading performance of the manufactured products is also poor, and can only meet lower shading requirements

Abstract

The invention belongs to the field of advertising materials, and relates to a preparing method of a digital printing shading fabric, in particular to water-based acrylate resin and a modified polymer-based high-flame-retardance full-shading advertising material thereof. The method includes the step of preprocessing a warp knitting fabric, scrape-coating one side of the warp knitting fabric with alayer of white slurry foamed through a foaming process, then a layer of black slurry foamed through the foaming process and finally a layer of qualified foam foamed through the foaming process or directly coating one side of the warp knitting fabric with transparent slurry through a direct-coating process, wherein the parameters of a foaming machine include the foam density of 250-400 g/L and themachine speed of 20-30 m/min. The prepared digital printing shading fabric has the advantages of being slightly elastic, high in softness and firmness and 100% high in shading; the most importantly, apattern to be digitally printed or printed is stable in image size and not prone to deformation, and images are of more textural quality due to the clear fabric surface.

Description

technical field [0001] The invention belongs to the field of advertising materials, and relates to a method for preparing a digital inkjet shading cloth, in particular to a water-based acrylic resin and a modified polymer-based highly flame-retardant full-shading advertising material. Background technique [0002] At present, most of the products in the industry adopt the direct coating process, and the performance is limited to excellent inkjet performance and certain flame retardancy. Different from the direct coating process, sprayable shading products need to be developed. When encountering such demands, the direct coating process is usually adopted to increase the amount of paste, and the surface is blackened so that the product has light-shielding properties. While such an operation satisfies the shading requirements, there are also many problems. Adopt direct coating process and increase the amount of sizing, which requires higher energy consumption to dry the coatin...
