AI Technical Summary

Problems solved by technology

The production of single emulsifier has few varieties of raw materials and simple process flow, but its emulsifying performance is poor, and the produced paraffin emulsion has low stability, poor dispersion and large average particle size, so paraffin emulsifiers are mostly made of single emulsifiers. compound emulsifier
Composite emulsifiers are obtained by compounding different types of emulsifiers. Using them can produce paraffin wax emulsions with high stability, good dispersion and small average particle size. However, most of these emulsifiers have many types of raw materials and complex process and other defects
At the same time, such emulsifiers usually use coal and petroleum as raw materials, and the problems of high energy consumption and poor environmental protection are also common.

Description

technical field [0001] The invention relates to a preparation method of papermaking materials, in particular to a paraffin composite emulsifier produced from bagasse and a preparation method thereof. Background technique [0002] Paraffin wax emulsifier can disperse paraffin wax in water to form emulsion, which is a key component in the production of paraffin wax emulsion, which is directly related to its application performance. The production of single emulsifier has few varieties of raw materials and simple process flow. However, its emulsifying performance is poor, and the produced paraffin emulsion has low stability, poor dispersion and large average particle size. Therefore, most paraffin emulsifiers are compounded with a single emulsifier. A complex emulsifier. Composite emulsifiers are obtained by compounding different types of emulsifiers. Using them can produce paraffin wax emulsions with high stability, good dispersibility, and small average particle size. Howeve...
