Problems solved by technology

[0004] The above-mentioned surface treatment agent is used to improve the surface feel and scratch resistance of synthetic leather. It is the same as most of the surface treatment agents on the market. It has a single function and cannot meet the requirements for the UV resistance of synthetic leather when it is used in bags and other places. It needs to be improved.

Abstract

The invention discloses a water-based surface treatment agent for synthetic leather and a preparation method thereof, and relates to the field of water-based polyurethane. The water-based surface treatment agent for synthetic leather comprises the following components in parts by weight: 100-120 parts of water-based polyurethane; 0.4-0.8 parts of polyurethane Dimethylsiloxane; 0.4-0.8 parts of defoamer; 1-2 parts of thickener; 1-3 parts of silicone feel agent; 3-7 parts of matting agent; 4-6 parts of UV-resistant particles. The anti-ultraviolet particles are lignin / zinc oxide composite particles, and the formed film layer has excellent anti-ultraviolet ability, so that the synthetic leather is not easy to accelerate aging due to ultraviolet rays. Nano-zinc oxide itself is a poor conductor of heat, which can prevent heat transfer. At the same time, lignin quaternary ammonium salt has a synergistic effect in heat resistance, which can effectively reduce the formation speed of oxygen free radicals and holes on the surface of zinc oxide under high temperature conditions. , so the anti-ultraviolet particles can improve the thermal stability of the formed film layer.

Description

technical field [0001] The invention relates to the field of water-based polyurethane, in particular to a water-based surface treatment agent for synthetic leather and a preparation method thereof. Background technique [0002] Since the output of natural leather cannot meet people's increasing demand, people have developed synthetic leather to replace natural leather. Synthetic leather mainly uses PU as a film-forming agent and non-woven fabric as a substrate, and is produced by wet coating and dry film transfer processes. After the production of synthetic leather, in order to make its surface gloss, feel and other properties close to or even surpass that of natural leather, it is often necessary to use surface treatment agents to treat its surface. [0003] The Chinese patent with the notification number CN103590248B discloses a water-based skin-feeling, scratch-resistant, scratch-resistant synthetic leather surface treatment agent, which consists of the following compone...
