Abstract

The invention provides an environment-friendly composite emulsifier for papermaking and a preparation method thereof. The formula comprises the following components by weight: 70-90 parts of sodium aliphatate, and 10-30 parts of Span-60. The preparation method includes: firstly putting sodium aliphatate into a reaction kettle and performing heating to 50-70DEG C, then adding Span-60 and performingstirring till complete melting, finally taking the product out of the reaction kettle and performing cooling to room temperature, thus obtaining a finished product. The product provided by the invention can be used in the production of paraffin, microcrystalline wax, beeswax and other emulsified waxes, and has the advantages of low dosage, low cost, good effect, environment-friendly raw materials, simple process, long shelf life, etc.

Description

technical field [0001] The invention relates to an emulsifying wax raw material for papermaking, belongs to the technical field of chemical industry, and in particular relates to an environment-friendly composite emulsifier for papermaking and a preparation method thereof. Background technique [0002] In the preparation of emulsified wax for papermaking, an emulsifier needs to be added. Its main function is to disperse the solid paraffin in water to form an emulsion, which is convenient for the wax to cover the surface of the paper, thereby improving the water and moisture resistance of the paper. The performance of the emulsifier has a great influence on the emulsification effect, stability and emulsifier dosage of the emulsion. Most of the existing products are made of Tween series and Siban series emulsifiers, which are difficult to achieve an ideal emulsification effect. There are problems such as excessive emulsifier dosage and yellowish emulsion color. Although emuls...
