Abstract

The invention discloses an emulsifying paraffin for an artificial board. The emulsifying paraffin comprises the following raw materials in parts by weight: 60-80 parts of paraffin, 18-22 parts of hydrophilic non-ionic surfactant, 8-14 parts of stearic acid, 0.1-0.5 part of fatty acid, 0.1-0.5 part of polysorbate, 1-3 parts of polystyrene, 1-3 parts of polyacrylamide, 0.5-1 part of sodium tripolyphosphate, 6-10 parts of ammonium dihydrogen phosphate, 0.01-0.05 part of carboxymethyl cellulose sodium, 0.8-2 parts of pentaerythritol, 4-8 parts of grease, 4-8 parts of paste starch, 10-15 parts of compound emulsifier and 80-120 parts of water. The emulsifying paraffin is capable of improving the stability, dispersity and waterproofness of the emulsifying paraffin and has the advantages of difficulty in demulsifying, uniform film formation, fine grain size, and the like.

Description

technical field [0001] The invention relates to the field of industrial chemical technology, in particular to emulsified paraffin wax for wood-based panels. Background technique [0002] Paraffin wax is one of the solid crystalline products extracted from petroleum. Paraffin wax emulsion does not need to be melted or dissolved when used. It has excellent properties such as acid resistance, alkali resistance, and hard water resistance. It also has the advantages of safety, efficiency, economy and convenience. It is widely used It is used in various industries, such as being used as a waterproof agent in the wood-based panel industry. Paraffin wax emulsion is used for wood waterproofing: apply the paraffin wax emulsion evenly on the surface of the wood that needs to be waterproofed by soaking or spraying. Because the paraffin wax emulsion has a fine particle size, it can naturally penetrate into the interior of the wood, and the waterproof effect can be achieved after drying. ...
