Abstract

The invention belongs to production of plywood and particularly relates to a special filler for plywood glue. The special filler is prepared by uniformly mixing effective dosages of pine bark powder, rice hull powder or peanut shell powder, attapulgite or quartz powder, puffed corn starch, sweet potato seedling powder or sweet potato flour residue, powdery preservative and Junbiqing, and the problems of high cost, bad color and bad water resistance in the prior art are solved in the invention. The special filler for plywood glue has the advantages of wide raw material source, reasonable compatibility, low cost and capability of removing formaldehyde and reinforcing water resistance of plywood, and the like.

Description

technical field [0001] The invention belongs to the production of plywood, in particular to a special filler for plywood glue. Background technique [0002] At present, in the process of making blockboard, plywood, and plywood for building formwork in our country's wood-based panel factories, the glue must be adjusted first. The so-called glue adjustment is to add a large amount of filler to the urea-formaldehyde glue to achieve thickening and facilitate the veneer. The purpose of gluing. At present, the main material used as filler is wheat flour. The amount of flour added is mainly determined according to the quality of the glue (mainly refers to the water content). Generally, the amount of flour added per ton of glue is between 30% and 40%. [0003] Publication No. 1820914 discloses a high-efficiency filler for plywood, which is a powder made by mixing organic and inorganic minerals such as wood powder, protein blood powder, etc., and is made of organic bentonite, inorga...
