Problems solved by technology

This will inevitably lead to a substantial increase in the cost of existing MDF, veneer and laminate flooring
In addition, the adhesives used in the production of existing medium and high-density fiberboards are generally UF or PF glue, which contains a large amount of free formaldehyde, which will cause a large amount of harmful substances polluting the environment to be released by itself and deep-processed products during use.

Embodiment 2

[0018] Embodiment two, the production process method of this embodiment is exactly the same as the production process method of embodiment one before paving and paving, but the demoulding process adopts the demoulding agent to demould. It needs to spray a release agent on the surface of the paving belt before paving. According to the metering, the surface material and the core material are fully mixed with their respective glues and then transported to the surface and core paving system. The glue used in the surface layer is MDI glue, accounting for 5%; the glue used in the core layer is MD glue, accounting for 7%. Afterwards, the pavement system paves evenly on the pavement belt from bottom to top in the order of the lower surface layer, the core layer, and the upper surface layer. The height and width of pavement are identical with embodiment one. After paving, spray the release agent on the upper surface. Subsequent production process method is identical with embodiment ...

Embodiment 3

[0019] Embodiment three, the production process of this embodiment is exactly the same as the production process of embodiment one before paving and after paving, except that the demoulding process adopts paper demoulding. It needs to lay a layer of paper on the paving belt before paving. Then, the surface layer material and the core layer material are calculated and finally mixed with their respective glues and transported to the surface layer and core layer paving system. The glue used in the surface layer is MDI glue, and the proportion is 3-15%. The additive is industrial urea, with a proportion of 1.5%; the glue used in the core layer is MDI glue, with a proportion of 5.15%. The additive is industrial urea, and the proportion is 1.5%. Afterwards, the pavement system is paved on the pavement belt from bottom to top and evenly in the order of lower surface layer, core layer and upper surface layer. The height and width of pavement are identical with embodiment one. After...

Abstract

Medium and high density artificial board is produced with wheat straw, rice straw, etc as main material; and the production process includes the steps of: wet fiber preparation, dry fiber preparation, mixing with glue, spreading, demolding, pre-pressing, hot pressing, board blank treatment, grinding and others. The medium and high density straw board may be further produced into facing board, reinforced floor board, etc. The medium and high density straw board may have performance similar to that of wooden fiber board, and is non-toxic and waterproof.

Description

Technical field [0001] The invention relates to a medium and high-density straw board produced by using agricultural waste (wheat straw and straw), and can be made into a veneer board and a reinforced floor through deep processing. Background technique [0002] The main raw materials of medium and high-density fiberboards, veneers and laminate floors currently on the market are wood. With the gradual reduction of timber resources and the strengthening of the work of protecting the ecological environment, the price of timber will continue to rise. This will inevitably lead to a substantial increase in the cost of existing medium and high density fiberboards, veneers and laminate floors. In addition, the adhesive used in the production of existing medium and high-density fiberboards is generally UF or PF glue, which contains a large amount of free formaldehyde, causing itself and deep-processed products to release a large amount of harmful substances that pollute the environm...
