Problems solved by technology

[0009] "Nanchang University" 2011 master's thesis "Exploration of Aqueous Polyurethane Acid Bath Coagulation Film Formation" paper discloses the use of acetic acid to foam water-based polyurethane emulsion to prepare synthetic leather, but also discloses that the surface and cross-section of WPU acid bath demulsification method have There are many microporous structures, among which the microporous structure without wood powder is richer than that with added wood powder, but no matter which one, compared with the solvent-based PU wet method, the microporous structure is still quite different. Therefore, WPU acid bath demulsification method needs further research from theory to practice

Abstract

The invention belongs to the field of wall cloth, and especially relates to a bamboo charcoal adsorption environment-friendly waterborne polyurethane wall cloth. The bamboo charcoal adsorption environment-friendly waterborne polyurethane wall cloth is prepared via foaming with bamboo vinegar; the tensile strength, tear resistance, and wear resistance are improved to achieve that of products obtained via DMF wet foaming; the obtained products are excellent in handfeel, fine in texture, excellent in permeability and sound insulation performance; no DMF is adopted in the whole production process; water is taken as a solvent; flame resistance is achieved; the obtained bamboo charcoal adsorption environment-friendly waterborne polyurethane wall cloth is safe, is friendly to the environment, and is low in cost; no formaldehyde or DMF is detected in the obtained bamboo charcoal adsorption environment-friendly waterborne polyurethane wall cloth; and requirements on ecological waterborne polyurethane wall cloth are achieved. The operationality of the technology is high, production efficiency is high, cost is low, and environment protection and industrialized large scale production are realized.

Description

technical field [0001] The invention relates to the field of wall coverings, in particular to a bamboo charcoal adsorption and environment-friendly water-based polyurethane wall covering. Background technique [0002] There are many kinds of interior wall decoration materials in the domestic market. Among them, the wallpaper wall cloth constructed by pasting technology has gradually replaced the paint because of its strong decoration and convenient construction. Clothed with a layer of PVC material, it is easy to warp and mold, crack and degumming after a long time. Ordinary wall coverings are easy to deform and stain because they are made of fabric, and have a short service life. They are not suitable for places with large traffic such as hotels. Thereby be badly in need of a kind of environmental protection life-span is long, sound insulation effect is good, the wall covering of exquisite appearance. [0003] Polyurethane synthetic leather has soft and natural luster, sof...
