High efficiency filling material for veneer board

Abstract

The high efficiency filling material for veneer board is mixed powder including stuffing wood powder, organic or inorganic bentonite and organic cellulose for thickening; wood adhering powder, water glass and protein blood powder for adhering and absorbing formaldehyde. The present invention has improved recipe, low cost, environment friendship and excellent application foreground.

Description

Technical field [0001] The invention relates to a high-efficiency filler for plywood. Background technique [0002] In the production of plywood, the solid content of the glue is between 48% and 50%. In order to increase the initial viscosity of the glue, ordinary flour should be used for glue adjustment. However, ordinary flour not only loses its adhesiveness after gelatinization and drying, but also is not resistant to water immersion, and the price is not low; flour is used as food and used on plywood, which also seriously wastes food resources. The present invention provides another kind of plywood filler, whose formula has been optimized and improved, using organic and inorganic minerals, such as waste sawdust in the production of plywood, leftover protein blood meal in meat joint factories, etc., which not only reduces the cost of raw materials, Moreover, it can increase the initial viscosity of the glue, is also viscous, and can absorb formaldehyde, which plays an en...
