Abstract
The calcium silicate board with the impregnated paper veneer comprises a calcium silicate board layer, wherein an adhesive coating is coated on the surface of one side of the calcium silicate board layer, a kraft paper layer is attached to the adhesive coating, an impregnated paper layer is attached to the kraft paper layer, and the impregnated paper layer is formed by stacking or attaching at least one layer of lignin phenolic modified resin or melamine resin impregnated paper. The surface of the calcium silicate board layer is pasted with a layer of impregnated paper, so that the waterproof performance is enhanced, the calcium silicate board layer can be directly used for outer wall decoration without processing, and the construction is simple; no other surface treatment of the calcium silicate board is required. The lignin modified phenolic resin impregnated paper and the melamine impregnated paper with different colors and different surface shapes are selected according to requirements, so that the single color tone and the facing effect of the calcium silicate board are changed, the breaking strength is increased, and the application range of the calcium silicate board is expanded.
Description
Technical Field
The utility model relates to a building material calcium silicate board especially relates to a calcium silicate board of gumming paper veneer.
Background
In recent years, calcium silicate boards have become novel materials for internal and external walls, ceilings, high-grade decoration materials, furniture fabrics and the like. However, the existing calcium silicate board has no decoration effect, has the defects of blank appearance, poor bending resistance and the like when being used for inner and outer wall bodies, ceilings, high-grade decoration materials, furniture fabrics and the like, and has insufficient waterproofness when being used for outer wall decoration.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the defect that prior art exists is overcome, a calcium silicate board that has decorativeness, can directly be used for outer wall fitment and gumming paper veneer that waterproof performance is good is provided.
The utility model provides a technical scheme that its technical problem adopted is: the calcium silicate board with the impregnated paper veneer comprises a calcium silicate board layer, wherein an adhesive coating is arranged on the surface of one side of the calcium silicate board layer, a kraft paper layer is attached to the surface of the adhesive coating, an impregnated paper layer is bonded on the kraft paper layer, and the impregnated paper layer is formed by stacking or bonding at least one layer of lignin phenolic resin modified resin or melamine resin impregnated paper.
Further, the kraft paper layer and the gum dipping paper layer are sequentially adhered to the surface of the other side of the calcium silicate board layer.
Further, the thickness of the calcium silicate board layer is 4.5-25 mm, and the density is 0.7-1.4 g/cu.cm.
Compared with the prior art, the utility model discloses a calcium silicate board layer is because surface paste has impregnated paper, and waterproof nature reinforcing can directly be used for the outer wall fitment without processing, and the construction is simple, need not carry out other surface treatment to the calcium silicate board. The lignin modified phenolic resin impregnated paper and the melamine impregnated paper with different colors and different surface shapes are selected according to requirements, so that the single color and the facing effect of the calcium silicate board are changed, the breaking strength is increased, and the application range of the calcium silicate board is expanded.
Drawings
Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention;
fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.
In the figure: 1. calcium silicate board layer, 2, adhesive layer, 3, kraft paper layer, 4, gum dipping paper layer.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the present embodiment includes a calcium silicate board layer 1, a kraft paper layer 3 is laid after a glue layer 2 is coated on one surface of the calcium silicate board layer 1, lignin-modified phenolic resin gummed paper or melamine gummed paper is glued on the surface of the kraft paper layer 3 by using a hot pressing technique to form a gummed paper layer 4, and the calcium silicate board is compounded into a gummed paper single-faced calcium silicate board. The impregnated paper layer 4 is formed by stacking or sticking at least one layer of lignin phenolic modified resin or melamine resin impregnated paper.
In the embodiment, the thickness of the calcium silicate board layer 1 is 5mm, the density is 0.7g/cu.cm, and the impregnated paper layer is 100 g/square meter lignin modified phenolic resin impregnated paper.
Example 2
As shown in fig. 2, the difference between this embodiment and embodiment 1 is that an adhesive layer 2 is also coated on the other side surface of the calcium silicate board layer 1, then a kraft paper layer 3 is laid, and then lignin-modified phenolic resin impregnated paper or melamine impregnated paper is adhered on the surface of the kraft paper layer 3 by using glue by using a hot pressing technique to form a impregnated paper layer 4, which is compounded into a impregnated double-faced calcium silicate board.
In the embodiment, the thickness of the calcium silicate board layer 1 is 25mm, the density is 1.4g/cu.cm, and the gum dipping paper layer is 40 g/square meter
The rest is the same as example 1.
Various modifications and variations of the present invention may be made by those skilled in the art, and they are within the scope of the present invention provided they are within the scope of the claims and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
