Abstract

The invention discloses a dry-skid charred bright finishing agent for synthetic leather, which comprises the following components in parts by weight: 50-75 parts of resin, 20-30 parts of ethyl acetate, 20-30 parts of isopropanol, 1-3 parts of silicon dioxide delustering powder, 1-4 parts of modified siloxane, 1-3 parts of flatting agent and 1-3 parts of water-sprinkling agent. The invention also discloses a preparation method of the dry-skid charred bright finishing agent for the synthetic leather. The components of the dry-skid charred bright finishing agent for synthetic leather cooperate to perform combined actions, and thus, the dry-skid charred bright finishing agent has favorable matting effect and unique skid wax sensation; after lustre finishing, the surface has charred brightness, and the leather face has favorable bright matting contrast effect; and the preparation method is easy to realize and is suitable for industrial production.

Description

technical field [0001] The present invention relates to a treatment agent for synthetic leather, in particular to a treatment agent for dry, slippery, scorching, and brightening treatment for synthetic leather, which is applied to the post-stage process of synthetic leather, and also relates to the treatment agent for dry, slipping, burning, burning, and brightening for synthetic leather method of preparation. Background technique [0002] Synthetic leather is usually a sheet-like product composed of a polyurethane resin composition laminated on a non-woven fabric, a woven fabric or a woven fabric, and its structure generally includes a base fabric and a polyurethane resin surface layer attached to the base fabric. The surface layer is mainly used for decoration and to achieve the effect of imitating natural leather. [0003] With the development of the times, there have been more and more changes in synthetic leather. According to the requirements of the designer, it is ho...
