Producing method of wood plastic hard material

Abstract

The invention belongs to the field of man-made board production, particularly to a producing method of a wood plastic hard material. The wood plastic hard material comprises 90% of fast-growing wood wools and the producing method of the wood plastic hard material comprises the following steps: impregnating modified phenolic resin water-soluble plastic solution into wood wool fiber and wood wool fiber cell cavities by a press injection method to compound the two high polymer materials; and then carrying out hyperpressure compression and high temperature solidification to obtain the wood plastic hard material of a certain specifications. The wood wools are all arranged vertically along the fiber for keeping the natural grains of wood and the wood plastic hard material has attractive appearance and good processability, and the physical-mechanical characteristic and the use function of the wood plastic hard material has designability, and the density, the strength, the compact resistance, the rotproofness and the water resistance, the nail-holding ability and other indexes of the wood plastic hard material are all higher than that of high-quality natural wood. The invention provides a novel wood plastic hard material to woodware industry and construction industry for improving the condition that large-diameter high-quality wood and hard wood resources are extremely rare and has the advantages of simple, practical and reliable producing process, higher yield and additional value.

Description

[0001] The invention belongs to the field of wood-based panel manufacture, and relates to a novel wood composite structural material, in particular to a manufacturing method of wood-plastic hard material. Background technique

[0002] At present, in the field of wood-based panel manufacturing, wood is used as raw material, urea-formaldehyde resin or phenolic resin is used as the adhesive between the woods, and various types of panels are made through different recombination processes. The artificial panels made by this method Its mechanical properties are low and cannot be used as a substitute for hard wood.

[0003] In my country's forest resources, large-diameter high-quality wood and hard wood resources with high density and high strength are extremely scarce, and various fast-growing wood resources are relatively sufficient. It is directly used in the manufacture of wood products such as doors, windows, floors, and furniture. Contents of the invention
