[0005] "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 mat, and especially relates to a white carbon black adsorption environment-friendly waterborne polyurethane mat. The white carbon black adsorption environment-friendly waterborne polyurethane mat is prepared via foaming with bamboo vinegar; tensile strength, tearing strength, and wear resistance are capable of reaching that of DMF wet foaming method; and obtained finished products possess advantages such as excellent handfeel, fine texture, and excellent permeability. No DMP is used in the whole production process; water is adopted as a solvent; flame resistance, safety, environment-friendly performance, and low cost are achieved. No formaldehyde or DMF is detected in the obtained white carbon black adsorption environment-friendly waterborne polyurethane mat, and requirement on environment-friendly waterborne polyurethane mats is satisfied.

Description

technical field [0001] The invention relates to the field of mats, in particular to a white carbon black adsorption and environment-friendly water-based polyurethane mat. Background technique [0002] Most of the existing high molecular polymer mats (or pads, gaskets) are made of plastic (such as PVC) and rubber materials. They are generally made by one-time integral injection molding or vulcanization, and the products made are resistant to low temperature. Poor performance, easy to harden and crack, feel astringent; production process of finished products is more, easy to cause dirty production environment, heavy odor, some raw materials (such as PVC) long-term close contact with human body will also affect human health, and, due to plastic The nature of the product determines that the product is easy to age, has poor wear resistance, and has a short service life. [0003] Polyurethane synthetic leather has soft and natural luster, soft hand feeling and strong genuine leat...
