Problems solved by technology

[0003] However, the existing wood fiber boards are produced by urea-formaldehyde glue, phenolic resin, etc. On the one hand, they have poor waterproof performance and can only be used in dry indoor environments, but cannot be used in humid environments or outdoor environments, and their durability is low; On the other hand, the workability is poor, the nail holding power is poor, and the screw is easy to loose after tightening, and its strength is not high, it is difficult to fix again, and it is easy to crack. It is generally used for flooring or as a shape-shaping material.

Embodiment 1

[0020] Such as figure 1 As shown, a modified solid wood fiberboard with silicon-magnesium materials is composed of molding agent, wood reinforcing fiber, water-retaining agent, and modifier. Silicon-containing materials and magnesium chloride are also added, and the modifier is mass percent A strong acid solution in the concentration range of 16%.

[0021] The strong acid is a mixture of phosphoric acid and oxalic acid.

[0022] The forming agent is magnesium oxide.

[0023] The wood reinforcing fiber is oak solid wood powder.

[0024] The silicon-containing material is silica fume.

[0025] The water-retaining agent is polydimethylsiloxane.

[0026] When the mixed raw materials are subjected to 1200 tons of high-pressure pressure, the board density is 1.2g / cm 3 , the compressive strength of the manufactured plate can reach 42MPa; the thickness of the 4-hour water expansion rate is less than 1‰, and the linear expansion shrinkage rate is less than 2‰.

[0027] The modifi...

Abstract

The invention belongs to the field of decorative boards, and particularly relates to a silicon-magnesium material modified solid-wood fiber board which consists of a forming agent, wood reinforced fibers, a water-retaining agent and a modifier. The silicon-magnesium material modified solid-wood fiber board is characterized in that a silicon material and magnesium chloride is further added, and themodifier is a strong acid solution with mass percentage concentration of 5%-30%.

Description

technical field [0001] The invention relates to the technical field of decorative boards, in particular to the field of modified solid wood fiber boards. Background technique [0002] There are many types of boards, such as wood fiber boards, acrylic boards, perlite fireproof boards, wood particle boards and dense boards, etc. Among them, wood fiber boards are one of the most widely used boards. Rich and beautiful texture, low cost, easy processing and other advantages, it has been listed as an important raw material since ancient times. [0003] However, the existing wood fiber boards are produced by urea-formaldehyde glue, phenolic resin, etc. On the one hand, they have poor waterproof performance and can only be used in dry indoor environments, but cannot be used in humid environments or outdoor environments, and their durability is low; On the other hand, the workability is poor, the nail holding power is poor, and the screw is easy to loosen after tightening, and its s...
