Sound-absorbing waterproof PVC(polyvinyl chloride) wallpaper base paper and preparation method thereof

Abstract

The invention relates to wallpaper base paper, in particular to a sound-absorbing waterproof PVC(polyvinyl chloride) wallpaper base paper and a preparation method thereof. The base paper is made from the following raw materials in parts by weight: 18-22 parts of bleached bagasse pulp, 30-40 parts of chemical bleached bamboo fiber pulp, 20-30 parts of poplar chemi-mechanical pulp, 3-5 parts of Fischer-tropsch wax of which the solid content is 20-25%, 10-13 parts of trepanned expanded perlite of 600-800 meshes, 1-1.5 parts of sodium borate, 1-2 parts of nekal, 1-2 parts of an aqueous antifoaming agent, 5-7 parts of a PAE(polyarylether) wet strength agent, 12-15 parts of environment-friendly pigment of 800-1250 meshes, 10-15 parts of an adhesive and 3-5 parts of an addition agent. For the base paper disclosed by the invention, the sodium borate is added in the process of pulping wood pulp, so that the water resistant capacity and the antiseptic capacity of the paper are improved; materials such as Fischer-tropsch wax aqueous emulsion and the trepanned expanded perlite are also combined, so that the semi-finished base paper has certain efficacies of water resistance, sound absorption and noise isolation; compound surface coating liquid on the surface of the semi-finished base paper can be effectively coated, the glued base paper is non-toxic, environment-friendly, stiff, smooth and level, the physical properties are good, the follow-up processing is facilitated, and basis is established for producing high-quality wallpaper finished products.

Description

Technical field [0001] The invention relates to a wallpaper base paper, in particular to a sound-absorbing and waterproof PVC wallpaper base paper and a preparation method thereof. Background technique [0002] As a wall decoration material, wallpaper has gradually become the first choice for many owners. It has the advantages of diverse colors, rich patterns, beautiful and environmentally friendly, and has many incomparable advantages over traditional wall materials. The usage rate in my country has been increasing year by year. PVC wallpaper is A common type of wallpaper, it mostly uses pure paper as the base material, and then the surface of the base material is coated with PVC resin sizing material, and then finished after finishing processing. [0003] The base paper as the base material directly affects the process effect and quality of the wallpaper in the later stage. At present, base paper materials generally have disadvantages such as strength, poor toughness, uneven surfa...

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
