Problems solved by technology

[0003] In order to overcome a series of problems caused by moisture absorption and deformation during the production and use of the above-mentioned existing impregnated paper laminated wood-based panels, especially composite laminated floors, the present invention provides a method for impregnated paper laminated wood-based panels, especially The exposed wood fiber surface at the edge of the composite laminate floor is waterproofed to prevent the board from being seriously deformed due to moisture absorption during production and use. This method can be used to impregnate the paper-laminated wood-based board after hot pressing. Entering the subsequent slitting process, there is no need to store and cure the semi-finished slabs for about 7 days to achieve the balance of moisture absorption, and the slabs after slitting no longer need about 3 days of keeping and curing for subsequent grooving and edge dipping treatment, the resulting finished panels are not easily deformed due to moisture absorption during subsequent storage, transportation, installation, and use. This method shortens the production cycle of impregnated paper laminated wood-based panels, reduces the rate of defective products, and reduces the The production cost solves the problem of a large amount of capital and inventory space being occupied, and solves the moisture-proof problem of impregnated paper laminated wood-based panels during storage, transportation, installation and use

Embodiment 1

[0009] In the heat-pressing stage of the composite laminate flooring production process, take two pieces of medium density fiberboard (2610mm×2070mm), before they are stacked with the bottom balance paper, the upper layer of decorative paper and the wear-resistant paper The exposed wood fiber surface on the longitudinal long side adopts roller roll coating and edge dipping method to roll coat a layer of waterproof resin and waterproof edge sealant, and then stack it with the bottom balance paper and the upper layer of decorative paper and wear-resistant paper before entering the press After pressing at 185°C, 3.5Mpa temperature and pressure for 30 seconds, the obtained three composite laminate floorings were cut and trimmed, and cut into six semi-finished boards of 1305mm×2070mm from the middle, and then cut directly without saving Form 60 slabs of 1305mm×202mm, including 12 edge slabs. The obtained slabs will be grooved immediately without storage, and the slabs that are groov...

Embodiment 2

[0011] In the heat-pressing stage of the composite laminate flooring production process, three pieces of medium density fiberboard (2610mm×2070mm) are taken, and before they are stacked with the balance paper of the bottom layer, the decorative paper and the wear-resistant paper of the upper layer The exposed wood fiber surface on the longitudinal long side is sprayed with a layer of waterproof oil-based waterproof edge sealant by vacuum spraying and edge dipping, and then stacked with the bottom balance paper and the upper layer of decorative paper and wear-resistant paper, and then enter the press at 185 ° C After pressing for 30 seconds under the temperature and pressure of 3.5Mpa, the obtained three composite laminated floors were cut and trimmed, and each was cut into six semi-finished boards of 1305mm×2070mm from the middle, and then cut into 60 pieces directly without preservation. 1305mm×202mm slabs, including 12 edge slabs, the obtained slabs are immediately grooved wi...

Embodiment 3

[0013] In the heat-pressing stage of the composite laminate flooring production process, take three pieces of MDF (2610mm×2070mm) and stack them with the balance paper on the bottom layer, the decorative paper and wear-resistant paper on the upper layer, and then enter the press at 185°C and 3.5Mpa. After pressing under pressure for 30 seconds, three composite laminate floors were obtained. When the three boards just came out of the press, the exposed wood fiber surface along the longitudinal long side was brushed with a layer of waterproof paraffin waterproof sealant by hand-painted edge dipping method. edge agent, and then cut and trim the obtained three pieces of composite laminate flooring and cut them into six semi-finished boards of 1305mm x 2070mm from the middle, and then directly cut them into 60 slabs of 1305mm x 202mm without saving them. There are 12 edge slabs in total, and the obtained slabs are immediately grooved on the long and short sides without being retaine...

Abstract

The invention discloses a method for preventing moisture absorption and deformation in the processes of production and use of a dipped paper lamination artificial board, which is characterized in that before or after the dipped paper lamination artificial board particularly a composite laminated floor board enters a press machine, an edge dipping method is adopted to coat one or more layers of a waterproof edge sealing agent on the surface of bare wooden fibers of two longitudinal long edges of the dipped paper lamination artificial board so as to slow down or block the absorption of moisture; the dipped paper lamination artificial board coming out of the press machine can be directly subjected to subsequent processing of slotting and edge dipping for preventing water and sealing the edges without subsistence and maintenance; and a finally-obtained finished product board particularly an edge board has no obvious phenomena of moisture absorption and deformation in the process of production and is not easy to absorb the moisture and deform in the processes of long-term storage and transportation and use in the future.

Description

Technical field [0001] The invention relates to a method for preventing impregnated paper laminated artificial boards, especially for preventing composite reinforced flooring from being deformed due to moisture absorption during hot pressing production and use. Before or after the boards, especially composite laminated floors, enter the press, apply one or more layers of waterproof edge sealant on the exposed wood fiber surfaces of the two longitudinal sides of the impregnated paper-laminated wood-based panels to slow down or block moisture. The impregnated paper-laminated wood-based panels that have been hot-pressed do not need to go through about 7 days of curing time for semi-finished boards and about 3 days of curing time for cutting and retaining slabs to perform final grooving and edge dipping treatment. The obtained finished board, especially the edge board, has no obvious moisture absorption deformation during production and use. Background technique [0002] In the...
