Abstract

The invention discloses a water-based blackening low-foaming composite wetting agent for synthetic leather and an application of the composite wetting agent. The composite wetting agent is prepared from the following raw materials in parts by weight: 50-90 parts of polyether modified organosilicone, 5-30 parts of a decyne diol polyoxyethylene ether surfactant and 5-30 parts of a fatty alcohol polyoxyethylene ether phosphate surfactant. The composite wetting agent provided by the invention has a remarkable effect on the dispersion and wetting of fumed white carbon black, effectively improves the blackening degree of the leather, and enhances the texture.

Description

technical field [0001] The invention relates to the technical field of wetting agents, in particular to a water-based blackening and low-foaming composite wetting agent for synthetic leather and its application. Background technique [0002] With the strengthening of environmental awareness, water-based leather finishing agents are gradually replacing the previous oil-based finishing agents. In water-based leather finishing agents, film-forming substances account for about 40% of the formula, and the remaining 60% are water and organic solvents. As we all know, the surface tension of water is 72mN / m, and its surface energy is very high, so it is difficult to wet the substrate with low surface energy. Therefore, in order to achieve good wetting and spreading effect, it is necessary to select a suitable substrate for wetting. agent, but for the special dynamic construction process of the ink, it is not possible to achieve wetting by reducing the surface tension, because the hi...
