Problems solved by technology

The disadvantages of this method are: the amount of emulsifier is large, the cost is high, the emulsified paraffin wax is easy to break and separate out when encountering acidic and alkaline media, and the stability of the emulsion is poor.
The emulsified paraffin particles produced by this invention are relatively large, about 300um, with poor stability and dispersibility

Abstract

The invention belongs to the technical field of chemical engineering, and particularly relates to emulsified paraffin for wood processing and a preparation method thereof. The emulsified paraffin for wood processing is prepared from paraffin, a compound emulsifier and water, wherein the compound emulsifier is a mixture of a Span type surfactant, a Tween type surfactant, alkylphenol polyoxyethylene and alcohol. The emulsified paraffin disclosed by the invention is non-toxic and tasteless, good in dispersibility, good in stability, acid-resistant and alkali-resistant; in the wood processing industry, the emulsified paraffin can completely substitute paraffin to be used as a waterproof and dampproof auxiliary, and is simple to use, low in cost and good in effect, compared with the paraffin; the preparation method is simple and feasible; the three wastes cannot be generated in the preparation process; the preparation method is environment-friendly and efficient.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to an emulsified paraffin wax for wood processing 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 (plastic products such as polyethylene). 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 in water under the action of mechanical external fo...
