Abstract

The invention discloses plywood slit filling putty. The plywood slit filling putty is prepared from the following main raw materials in parts by weight: 6-14 parts of bentonite, 1-5 parts of a pigment, 11-17 parts of a zinc stearate emulsion, 4-11 parts of a thickening agent, 9-16 parts of urea-formaldehyde glue, 3-6 parts of a defoamer, 3-6 parts of nanometer zinc oxide, 8-13 parts of titanium dioxide, 5-9 parts of petroleum coke powder, 4-7 parts of a dispersing agent, 2-5 parts of attapulgite, 5-10 parts of seaweed gel, 1-3 parts of polyvinyl alcohol, 9-17 parts of mung bean starch, 1-5 parts of tributyl phosphate and 4-7 parts of hydroxymethyl cellulose. The plywood slit filling putty is used for filling slits after hot rolling of a plywood, is unlikely to collapse, is good in smoothening effect and high in strength, is unlikely to shed off, and is good in product performance, simple in preparation process and low in cost.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a putty for filling gaps in plywood. Background technique [0002] Plywood, also known as plywood and thin-core board, is a three-layer or multi-layer board-like material that is made of wood segments that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. board, and make the fiber directions of adjacent layers of veneers perpendicular to each other and glue them together. Plywood is a kind of wood-based panels. Because of its small difference in physical and mechanical properties in the vertical and horizontal directions, high wood utilization rate, light weight, and low price, it is widely used in furniture manufacturing, aircraft, ships, trains, automobiles, and construction. and packing boxes and other fields. Plywood generally needs putty to fill holes, gaps, glue openings and other defects on the plywood after hot pressing. Howe...
