Example 1

Referring to fig. 1, the embodiment provides a wear-resistant moisture-proof impregnated paper solid wood composite board, which includes a wear-resistant layer 1, a decorative paper layer 2, a wear-resistant impregnated titanium white paper layer 3, a core board 4, an impregnated titanium white raw paper layer 5, and an impregnated balance paper layer 6, which are bonded by hot pressing from top to bottom.

The multilayer structure is bonded on the upper surface of the core plate 4 by hot pressing, so that the physical and mechanical properties of the composite plate, such as wear resistance, deformation resistance and the like, can be effectively improved; the multilayer structure is bonded on the lower surface of the core plate 4 in a hot-pressing manner, so that the moisture resistance, mildew resistance and other properties of the composite board can be effectively improved; thereby effectively avoiding the problems of cracking, mildewing, shrinkage joint, expansion, arching and the like of the composite board in the using process.

In this embodiment, the wear-resistant layer 1 is alumina wear-resistant particles; the decorative paper layer 2 is gum dipping patterned paper; the thickness of each layer of the wear-resistant layer 1, the decorative paper layer 2 and the wear-resistant impregnated titanium white paper layer 3 is 0.2 mm; the thickness of each layer of the impregnated titanium white raw paper layer 5 and the impregnated balance paper layer 6 is 0.2 mm; the surface wear-resistant layer 1 is covered on the impregnated patterned paper by aluminum oxide wear-resistant particles, is wear-resistant and durable, and overcomes the defect that the UV or PU paint surface of the common solid wood composite floor is not wear-resistant;

the surface of the core plate 4 is bonded with the wear-resistant impregnated titanium white paper layer 3, and the surface of the core plate 4 is bonded with the impregnated titanium white raw paper layer 5, and the titanium white raw paper layer contains cotton fiber, so that the strength is high, on one hand, the tension, the tensile strength and the toughness of the product structure are good, and the problems of the product in the same industry such as cracking, bulging, wrinkling, orange peel and the like can be effectively solved; on the other hand, the wear-resistant impregnated titanium white paper layer 3 can increase the advantage of better wear resistance of the surface after high-temperature hot pressing (about 2000 r when an aluminum trioxide wear-resistant layer is formed on the surface can be increased to about 4000-; the titanium white raw paper layer 5 is bonded and impregnated on the bottom surface of the core plate 4, so that the core plate 4 can be effectively prevented from cracking, crazing and the like, and the plate can have good deformation resistance, cracking resistance, water resistance, moth resistance and the like under high-temperature and high-humidity conditions; it should be noted that, when bonding, the length directions of the wear-resistant impregnated titanium white paper layer 3 and the impregnated titanium white raw paper layer 5 need to be perpendicularly pressed to the wood grain direction of the surface of the core board 4, so that the overall crack resistance of the board can be further promoted. That is to say: the manufacturing direction of the cotton fiber titanium white paper is perpendicular to the wood grain direction of the base material surface (because the transverse strength and the longitudinal strength of the paper are different and are one-dimensional anisotropy, the transverse cracking of the wood skin fiber is effectively controlled by utilizing the longitudinal tension of the cotton fiber paper).

In addition, the wear-resistant impregnated titanium white paper layer 3 is bonded on the surface of the core plate 4, the wear-resistant impregnated titanium white paper layer 3 is prepared by bonding a layer of aluminum oxide wear-resistant particles on the surface of the impregnated titanium white raw paper layer 5, and the wear-resistant impregnated titanium white paper layer 3 is bonded on the surface of the core plate 4, so that the wear resistance of the composite board can be effectively improved; the bottom layer of the core plate 4 is bonded with the impregnated titanium white raw paper layer 5, so that the upward warping stress generated after the surface layer structure of the composite board is hot-pressed can be offset in an auxiliary manner, and the composite board is kept straight and flat; and the bottommost layer can play the roles of moisture resistance, water resistance, moth prevention and the like.

In this embodiment, the core board 4 is pre-processed to be convex warped; the core plate 4 is used for producing the wallboard, and the warping degree formed by the surface of the core plate in the length direction is 3%, and the warping degree formed by the surface of the core plate in the width direction is 1%.

Because the larger the width of the core plate 4 is, the larger the stress generated by hot pressing is, the larger the warping degree needs to be set to generate larger prestress, and the larger the prestress can be offset from the original stress, so that a straight composite plate is generated.

In order to increase the wear resistance and the physical mechanical property of the surface of the composite board, the upper surface of the core plate 4 adopts a three-layer structure, the lower surface of the core plate 4 adopts a two-layer structure, when the total thickness of the surface layer is equal to that of the bottom layer, and the surface layer and the bottom layer are both made of multi-layer paper layers, under the condition that the thickness and the material are not different greatly, the shrinkage coefficient of the upper surface of the core plate 4 after being cooled to normal temperature and normal humidity is larger than that of the lower surface of the core plate 4 after hot pressing because the number of layers of the upper surface of the core plate 4 is larger than that of the lower surface of the core plate 4, and if the straight core plate 4; if the upper surface of the core plate 4 and the lower surface of the core plate 4 adopt the same layer structure, the production cost can be greatly increased; this application then establishes core 4 to protruding warpage type, offsets with the stress of originally upwards warping when hot pressing, even composite board keeps straight.

In this embodiment, the core 4 is a multi-layer plywood; the upper layer and the lower layer of the multilayer plywood are vertically staggered, so that the rebound foot feel is good, and the multilayer plywood is not easy to deform; and the bottom plywood of the multilayer plywood uses the balance veneer, can resist the shrinkage stress after the surface layer structure of the multilayer plywood is hot-pressed, make the core board keep straight as much as possible, and have anticorrosive mothproof function.

In this embodiment, the thickness of the composite board is 12 mm; is convenient for laying and using.
