Abstract

The invention discloses an antibacterial mildew-resistant synthetic leather. The synthetic leather comprises a basic cloth layer, a PVC foam layer, and a PU surface layer. The surface layer is composed of the following raw materials in parts by weight: 80 to 100 parts of aqueous polyurethane resin, 10 to 15 parts of beta-cyclodextrin, 1 to 2 parts of litsea cubeba oil, 0.5 to 1 part of anise oil, 0.2 to 0.5 part of frankincense oil, 2 to 4 parts of xanthan gum, 2 to 6 parts of shell powder, 1 to 3 parts of barite powder, 0.2 to 0.5 part of barium stearate, 0.2 to 1 part of triethanolamine, 0.2 to 0.5 part of potassium fulvate, 0.2 to 1 part of poly(epoxy sodium succinate), 0.5 to 1.5 parts of allantoin, 2 to 4 parts of modifying aids, and 2 to 4 parts of pigment. The provided synthetic leather can effectively prohibit the microbe propagation on leather, and prevents mildew and corrosion at the same time. The effects on preventing bacteria and mildew can last for a long time. Moreover, the leather quality is stable, the service life is prolonged, and the latent hazard to human health is reduced.

Description

technical field [0001] The invention relates to the technical field of synthetic leather processing, in particular to an antibacterial and mildew-proof synthetic leather and a production method thereof. Background technique [0002] Polyurethane (PU) synthetic leather has the characteristics of cold resistance, good hand feeling and appearance quality, high strength, good moisture absorption and air permeability, and no polyvinyl chloride (PVC) artificial leather is hard in winter and soft and sticky in summer. It has become the best substitute for natural leather. choose. The surface of synthetic leather is easy to breed microorganisms, leading to a series of problems such as mildew, aging, and performance degradation, which not only affects the quality and service life of synthetic leather, but also endangers human health. Contents of the invention [0003] The object of the present invention is to provide an antibacterial and antifungal synthetic leather. [0004] The...
