Problems solved by technology

[0004] Through a large number of experiments, the inventor found that the oxidized polyethylene wax microemulsion prepared by the above-mentioned patent has defects in stability and application performance.
For example, the acid resistance stability of its finished product is relatively poor, and a small amount of pH value reduction can lead to flocculation or even coagulation of the microemulsion; while the anionic microemulsion particles of the finished microemulsion fail to effectively attract and adhere to the surface of the target object, only adding Use large amounts to achieve the desired application effect
The wax emulsion particles remaining in the solution not only fail to be utilized, but also increase the difficulty of wastewater treatment

Abstract

The invention relates to a microemulsion composite of polyethylene wax oxide, comprising 5 to 40% of polyethylene wax oxide in weight, 2 to 20% of nonionic surfactant in weight, 0.1 to 5% of cation surfactant in weight, 0 to 5% of assistant emulsifier in weight and 40 to 92% of water in weight based on the total weight of the microemulsion composite of polyethylene wax oxide. The microemulsion composite of polyethylene wax oxide of the invention has transparent appearance, good dispersibility and stability, and better acid resistance and applicability compared with the conventional microemulsion of polyethylene wax oxide. The microemulsion composite of polyethylene wax oxide of the invention can effectively enhance the sewing smoothness of the knit fabric.

Description

Technical field [0001] The invention relates to an oxidized polyethylene wax microemulsion composition, a preparation method and application thereof. Background technique [0002] Oxidized polyethylene wax is a modified product in which polyethylene wax is oxidized to introduce polar groups such as -COOH, -OH, and -CO-. Compared with polyethylene wax, oxidized polyethylene wax has better emulsifying properties. In recent years, due to the development of microemulsion technology, the preparation of oxidized polyethylene wax emulsion has become a hot spot in the research and development of auxiliary workers. Because of its excellent properties, oxidized polyethylene wax microemulsion has been widely used in leather, papermaking, textile and daily chemical industries. It is often used in acidic conditions when applied in leather, paper, textile and daily chemical industries. Under use.
