Description
The cross reference of related application
The application requires the priority of the U.S. Provisional Application sequence number 61/016,952 submitted on December 27th, 2007, and the disclosed content of this application is inserted this paper by reference.
Technical field
The present invention relates to a kind of method that engineered wood product (such as directional structure board OSB) makes its resistance to water with improvement, covering power, retentivity (holdout) and product appearance that is used to be coated with.
Background technology
Engineered wood product such as directional structure board, fiberboard and laminated veneer lumber (LVL) extensively are used in dwelling house and the commercial building, and it becomes in the market such as materials handling (material handling) and ornament furnishings manufacturing and becomes more and more popular.These products can obtain by various forms, such as directional structure board, medium density fibre board (MDF) (MDF), laminated veneer lumber, or the like.
Engineered wood product is usually by the adhesive manufacturing of small pieces timber and heat cure.Directional structure board is made by the adhesive of heat cure with the rectangle batten that intersection oriented layer form is arranged usually.These are commonly called the engineering structure plate, and their purposes comprises roof boarding, shingle nail and is used for the floor of dwelling house family expenses building.Manufacturing process makes sheet material manufacturer may provide such as the new type of component of slip-resistant texture for the sheet material that roof boarding designs or supplies super-huge, metric system sheet material.
Contact the engineered wood product that makes such as OSB sheet material with water and experience thickness swell (thickness swelling) inevitably.Usually observe the most serious swelling behavior at the edge of sheet material.The edge that exposes in the engineered wood board is often obvious than center swelling.For example, thickness be 720 mils (0.720 inch, OSB sheet material 1.829cm) in fact be swelling to edge thickness to surpass 1000 mils (1 inch, 2.54cm).After the drying, these sheet materials can't recover its original thickness, and the substitute is and being dried to the swelling edge thickness is about 900 mils.
The scheme that has a plurality of solution edge swell problems.The manufacturer of most of engineered wood products (such as the OSB sheet material) attempts to apply the dimensional stability of improving this sheet material such as the sealing compositions of coating preparation by all four edges to the OSB sheet material.Usually, the dry hydrophobic membrane that forms of sealant, it is attached on the OSB sheet material and suppresses water and is absorbed into the sheet material edge.Therefore, this edge sealant can help sheet material to reduce the edge swell degree that is experienced when it is exposed to water.
Edge sealant is coated on the engineered wood product such as the OSB sheet material usually during fabrication.Liquid sealing preparation is being applied on the sheet material after the manufacturing usually immediately.Usually, the rapid draing after being coated on the sheet material of this preparation, and need not to use heater or ventilation unit.Apply sealant and be considered to industrial standard, it provides aesthetic values for common sale purpose and provides performance advantage to assist the water sensitive sheet material to avoid to make moist the erosion of vapour and rainwater during dwelling construction.
Great majority sealing preparation is coloured, gives reliable, uniform, attracting outward appearance on the engineered wood product unit thereby it is applied to.Behind the edge and drying that sealant are coated to engineered wood product, it should reduce these goods and be exposed to the thickness swell that water can take place usually.Therefore, sealant should dry formation can be attached on the woodwork and quite flexible film, and it can expand along with the swelling of woodwork, stretch as a result.
Still need to improve the method for protection the engineered wood product that may be exposed to natural environment (for example water) toward the client between the delivery period (specifically being the surface and the edge of base material).
