Embodiment 1

[0019] Embodiment 1: a kind of paraffin wax emulsion, it is characterized in that, the parts by weight of each component are: 22 parts of paraffin wax, 6 parts of hydrophilic nonionic surfactants, 7 parts of stearic acid, 9 parts of compound emulsifiers, thickener 1. 16 parts of oil and 45 parts of water.

[0020] Its production steps are:

[0021] (1) sequentially add the water-based non-ionic surfactant and paraffin wax in the formulated amount and mix to obtain the first mixture;

[0022] (2) mixing the first mixture obtained in the step (1) with water, stearic acid, compound emulsifier and thickener;

[0023] (3) Heat the second mixture to 90-93°C. After the mixture is completely melted, use a net bag to remove solid impurities, and stir the mixture at a stirring speed of 100-120 rpm; keep the temperature at 92-100°C , stirring for 60 minutes;

[0024] (4) Stir the mixture at a stirring speed of 900-1200 rev / min and slowly add the oily ester. The oily ester must be ...

Abstract

The invention discloses a paraffin emulsion. The paraffin emulsion is characterized by comprising the following components in parts by weight: 15-30 parts of paraffin, 6-15 parts of a hydrophilic nonionic surfactant, 4-7 parts of stearic acid, 5-10 parts of a compound emulsifier, 1-2 parts of a thickening agent, 8-20 parts of grease and 30-50 parts of water. The paraffin emulsion has the beneficial effects that the emulsion is not easy to break; the stability is high; an operation process is simple and convenient; the water resistance and the mechanical performance of an artificial board can be improved; the quality of an artificial board product is improved.

Description

[0001] technical field [0002] The invention relates to an emulsion, in particular to a paraffin emulsion. Background technique [0003] Wood-based panels include fiberboard and particleboard, both of which are products of comprehensive utilization of wood in the wood industry. In addition to wood fibers or sawdust, their components also need a certain proportion of glue, so that wood fibers or sawdust are hot-pressed. Handle glue molding. A certain amount of paraffin wax emulsion is mixed with the size to make the board water-resistant and improve the surface finish. Due to the small particle size of paraffin wax emulsion, in the process of man-made board manufacturing, through effective demulsification, tiny wax particles can be precipitated from the water phase and evenly adsorbed on wood fibers. In developed countries, there is no one that does not use it. Particleboard and fibreboard produced from emulsified wax. [0004] Paraffin wax emulsion is used for wood wate...
