Effect of Mineral Composite Fillers on Properties of Man-Made Plywood

Abstract:

Attapulgite mineral powder as raw material, through surface modification and composite of various mineral processing, the effect of modifier dosage, composite powder filler ratio on the mechanical properties and formaldehyde emission of the plywood which is bonded by filled urea-formaldehyde resin were investigated. The results show that under the conditions of the plywood bonding strength to meet the national standard, modified attapulgite make the plywood formaldehyde emission decrease from 4.5 to 2.1 mg/L, the composite material can make the formaldehyde emission decreased to 1.6 mg/L, which can improved the indoor environment and the grade of plywood.
