Embodiment 1

[0021] A paraffin wax emulsion, the main components and their weight proportions are: 10 paraffin wax, 1 stearic acid and 1 ammonia water.

[0022] The preparation method of above-mentioned paraffin emulsion, its processing step is:

[0023] Step 1: Weigh 500kg of paraffin and 50kg of stearic acid according to the weight ratio, add 1300kg of water and put them into the emulsification tank, turn on the steam to raise the temperature to 90°C, then turn off the steam, after the paraffin is completely dissolved, turn on low-speed stirring, and keep warm for 60 minute;

[0024] Step 2: After the first step of heat preservation, stir at high speed for 10-15 minutes, slowly add 50kg of ammonia water into the emulsification tank, and continue stirring at high speed for 20 minutes after adding ammonia water;

[0025] Step 3: After the treatment in the second step, turn on the cooling water for cooling, and discharge when the temperature drops to 40°C to obtain a paraffin wax emulsion ...

Abstract

The invention relates to wax emulsion and a manufacture method of the wax emulsion. The wax emulsion comprises the main components by weight: 22-28% of paraffin wax, 2-3% of stearic acid and 2.2-2.8% of ammonia water. The use amount of a used emulsifying agent is small and is only 1 / 2-1 / 3 of that in the prior art. The produced wax emulsion is strong in product stability, and has the advantages of acid resistance, alkali resistance, hard water resistance, strong water solubility, stable emulsion, no layering while being diluted with water in any proportion, no demulsification, no agglomeration, long storage life, high solid content and good dispersibility, so that waterproof and mechanical properties of artificial boards are improved, and the product quality of the artificial boards is improved.

Description

technical field [0001] The invention belongs to the technical field of new polymer material production, and relates to a paraffin emulsion used for producing wood-based panels and a production method thereof. Background technique [0002] 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. Particleboar...
