Abstract

The invention relates to the making of high intensity water resistant compound material, which is made by natural plant fiber 20-85 kg being 20-85%, organic monomer 5-60kg being 5-60%, inorganic stuff being 1-20% with 1-20kg, chemical assistance 1-10kg being 1-10%, iniator 0.05-2kg being 0.05-2%, spare material being the primary mixing of natural plant fiber and organic monomer, then with initiator controlling the temperature, filing inorganic stuff and chemical assistance for further mixing, activating the mixture to get the high temperature and high pressure forming product, or compressing, extruding or injecting the wanted product. It can be used for the production of plates, tubes and section bars. It is water resistant, free from contamination, strong in plasticization, and low in cost.

Description

technical field [0001] The high-density water-resistant composite wood material and its production method of the present invention relate to the technical field of building materials; in particular, to the technical field of materials and methods for building materials; especially to the technical field of materials and methods for high-density water-resistant composite wood building materials; specifically, to the technical field of high-density water-resistant composite wood materials And the technical field of production method. Background technique [0002] At present, wood generally has the defect of swelling when wet and shrinking when dry, and its size and shape are greatly affected by environmental changes. Taking the existing wood-based panels on the market as an example, the density of general particleboard, fiberboard, OSB, MDF and other products is less than 1.0g / cm 3 , It contains many adhesives such as phenolic formaldehyde and urea formaldehyde, and the resid...
