Abstract

A method to apply waterproof emulsified paraffin wax in fibreboard production includes emulsifying paraffin wax in water with emulsification additive to let paraffin wax solid content up to 40-50 % of being used as waterproofing agent, applying it in fibreboard production and drying all hydrophilic contents in emulsification agent off at drying process of 100-180 deg.C for achieving purpose of waterproof for fibre.

Description

field of invention [0001] The invention relates to a method for manufacturing waterproof emulsified paraffin, in particular to a waterproof emulsified paraffin used as a waterproofing agent in fiberboard production and other wood processing. Background of the invention [0002] The traditional waterproof and moisture-proof technology used in the existing domestic fiberboard production and wood processing industry is a processing technology in which solid paraffin is sprayed into the fiber material after being hot-melted, and combined with the fiber after stirring. Due to the large spray particles and high paraffin consumption, the product quality is affected to a certain extent. [0003] With the rapid development of the fiberboard industry, the requirements for the quality of fiberboard are getting higher and higher. Therefore, waterproof emulsified paraffin wax, as a low-cost and effective waterproofing agent, is a new product that appears in response to this trend. [00...
