PVC base wallpaper using tea saponin as efficient retention and drainage agent and preparation method of PVC base wallpaper

Abstract

The invention relates to a piece of base wallpaper, in particular to a PVC base wallpaper using tea saponin as an efficient retention and drainage agent and a preparation method of the PVC base wallpaper. The base wallpaper is prepared from the following raw materials in parts by weight: 25-30 parts of bleached straw pulp, 40-50 parts of bleached hardwood pulp, 4-6 parts of polyoxyethylene, 1-2 parts of tea saponin, 2-4 parts of hydroxypropyl distarch phosphate, 4-6 parts of a PAE wet strength agent, 1-2 parts of calcium formate, 1-2 parts of dodecyl benzene sodium sulfonate, 1-2 parts of an aqueous antifoaming agent, 10-13 parts of 600-800-mesh sericite powder, 10-15 parts of 800-1250-mesh environment-friendly pigment, 12-15 parts of an adhesive and 3-5 parts of an auxiliary. According to the base wallpaper disclosed by the invention, raw materials such as polyoxyethylene, and tea saponin are added in a mashing process, so that the pulp material is easier to prepare; the tea saponin has good retention and drainage efficacies, so that the strengthening effect of the sericite powder is improved, the raw materials are more sufficiently utilized, compounded surface coating liquid is easy to coat, the base wallpaper, to which the glue is applied, is non-toxic and environment-friendly, the surface of the base wallpaper is level, stiff and smooth, the base wallpaper is not easy to dampen and deform, the physical performance is good, the after-treatment is easy, and the foundation is established for producing high-quality finished product wallpaper.

Description

technical field [0001] The invention relates to a wallpaper base paper, in particular to a PVC wallpaper base paper using tea saponin as an efficient retention and drainage aid and a preparation method thereof. Background technique [0002] As a wall decoration material, wallpaper has gradually become the first choice of many owners.

Problems solved by technology

[0003] Base paper as the base material directly affects the process effect and quality of wallpaper in the later stage. At present, base paper materials generally have disadvantages such as poor strength, poor toughness, uneven surface absorption, difficult application of glue, poor water resistance and heat resistance, and mold growth. , seriously affects the performance of the finished product, so it is very important to improve the formula and process of traditional base paper, improve its adaptability, and improve the post-processing performance to achieve efficient production and obtain high-quality products
