Abstract

The invention provides an emulsion paraffin water-proofing agent for a particleboard. The emulsion paraffin water-proofing agent is prepared from solid paraffin, stearic acid and water as main raw materials, peregal-O and polysorbate as emulsifiers, sodium tripolyphosphate as a catalyst, and sodium carboxymethylcellulose as a cross-linking agent through step-by-step emulsification and saponification. The water-proofing agent has the advantages of high solid content, uniform film-forming property, small granularity, significant dispersity and waterproofing effect, simplicity in preparation process, easiness in production and operation, and low demands on equipment and process condition, can be produced by an artificial board glue manufacturing workshop without adding equipment, and is high in quality and low in price.

Description

technical field [0001] The invention relates to a waterproofing agent used in the production of hydrophilic and lipophilic artificial boards, in particular to an emulsified paraffin waterproofing agent used in the production of particle boards and a manufacturing method thereof. Background technique [0002] In the particleboard production process, in order to increase the waterproof performance of the particleboard, a waterproofing agent is usually applied. In recent years, the rapid development of my country's particleboard production has resulted in a shortage of petrochemical raw and auxiliary materials for particleboard production. Paraffin is widely used as the main waterproofing agent for particleboard production. Prices continue to move higher. At present, many manufacturers and scientific research institutions are looking for other waterproofing agents to replace paraffin. Emulsified paraffin wax waterproofing agent is made of paraffin wax as a carrier, togethe...
