However, the surface film of this kind of panel is mostly made of cold paste, that is, it is mainly bonded by white latex, and white latex contains a certain amount of formaldehyde, which will cause harm to the human body and fail to meet environmental protection standards.
Moreover, the use of white latex for cold bonding is prone to surface film dehydration and degumming in humid environments, which seriously affects the quality of the veneer.

Abstract
The invention discloses a cement fiber melamine laminated board, which comprises a cement fiber base board (1) and is characterized in that a melamine impregnated paper laminated layer (2) is adhered on the cement fiber base board (1). The invention further discloses a manufacturing method of the cement fiber melamine laminated board, which mainly adopts a hot-pressing process. Hot-pressing pressure is 1000 to 1200 tons, hot-pressing time is 45 to 50 seconds, and hot-pressing temperature is 170 DEG C to 190 DEG C. The cement fiber melamine laminated board has the advantages of being low in cost, good in fireproof and dampproof effects and convenient to install, and the surface of the board is not easy to scratch and crack, cannot bleed water when weather is wet, and is not easy in adhesive failure.
Description
technical field [0001] The invention relates to a cement fiber melamine veneer and a preparation method thereof. Background technique [0002] In recent years, there are many kinds of materials used for decoration materials, such as MDF, glass magnesium board, etc., but their fireproof, moisture-proof and environmental protection requirements cannot be met. Another example is granite, marble, tiles, etc., but there are defects such as high price, heavy weight, easy surface scratches, cracks, and troublesome installation. [0003] In the prior art, there are also veneers used to replace granite, marble, ceramic tiles, etc., that is, a layer of surface film is pasted on the substrate to form a composite board. However, the surface film of this kind of panel mostly adopts the method of cold paste, that is, it is mainly bonded by white latex, and white latex contains a certain amount of formaldehyde, which will cause harm to the human body and fail to meet environmental protect...
