Abstract

The invention relates to a thermodynamic self-emulsifying high-efficiency emulsifier of paraffin for wood softening and a preparation method thereof. The emulsifier adopts Span 60, fatty alcohol polyoxyethylene ether, stearic acid polyoxyethylene ether or alkylphenol ether Sulfosuccinate sodium salt is used as a raw material and carried out in an appropriate weight ratio to finally prepare an emulsifier, which has good emulsification effect, stable product quality, and long storage time, and the preparation process of the emulsifier is simple. Serve immediately after mixing. The paraffin is further emulsified by using the emulsifier, the amount of the emulsifier is small, and the prepared emulsified paraffin has good stability, acid resistance, alkali resistance and good waterproof performance.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a thermodynamic self-emulsifying high-efficiency emulsifier of paraffin for wood softening and a preparation method thereof. Background technique [0002] The full name of paraffin is petroleum wax, which is flaky or needle-like crystals obtained from lubricating oil distilled from crude oil distillation through solvent refining, solvent dewaxing, and then solvent deoiling and refining. Paraffin wax is widely used and biodegradable, which has better environmental performance than other alternatives such as polyethylene and other plastic products. However, since paraffin is solid at room temperature, it cannot meet the diversity of uses or is inconvenient to apply, so people study emulsified paraffin to make up for its deficiency. [0003] Emulsified paraffin is a homogeneous fluid containing wax and water made by dispersing hydrophobic solid paraffin evenly...
