Specific embodiment
In the following, referring to the utility model relates to attached drawing be described in detail.
As shown in Figure 1, the utility model relates to house decorative material plate 1 include: first size enhancement layer 10；Core
Layer 30, is formed on first size enhancement layer 10；Second size enhancement layer 50, is formed on sandwich layer 30.
In the present invention, the first size enhancement layer 10 and the second size enhancement layer 50 are by fabric nonwoven cloth heat
The sheet shape for squeezing and being formed, plays the work of the water resistance and dimensional stability that can ensure house decorative material plate
With.
By fabric nonwoven cloth manufacture at comprising synthetic resin fiber and reinforcing fibre, when with 30 hot extrusion of sandwich layer,
Melting by the synthetic resin fiber contained in fabric nonwoven cloth can also be bonded without other adhesives with sandwich layer.It is preferred that
Ground, the weight ratio of synthetic resin fiber and reinforcing fibre in the fabric nonwoven cloth are 5:5~7:3.When the weight of reinforcing fibre
When amount is than being greater than 5, although tensile strength or bending strength increase, the weight of opposite synthetic resin fiber is reduced, and makes nothing
The bad formation of woven fabric, the non-woven fabrics embrittlement (brittle) of formation, thus it is undesirable, when less than 3, because of tensile strength or bending resistance
Intensity is weak, so undesirable.Moreover, manufacturing the non-woven fabrics of porosity material when the weight ratio of synthetic resin fiber is greater than 7
Meaning desalination, when less than 5, the bad formation of non-woven fabrics, it is therefore preferred that synthetic resin fiber in fabric nonwoven cloth with plus
The weight ratio of strong fiber is 5:5~7:3.
The synthetic resin fiber is thermoplastic resin, using the feature of environmental protection material polyene for not discharging harmful substance relatively
Fibrids.
Preferably, the polyolefin fibrids utilize polyethylene fibre, polypropylene fibre or polyethylene terephthalate
Ester fiber.The polyolefin fibrids can be the fiber of single resin, or as the fiber of nucleocapsid structure, can will be used for shape
The fiber of nucleation uses resin manufacture of the same race or xenogenesis with the coating resin for being used to form shell.
As the reinforcing fibre, one of glass fibre, carbon fiber (aramid fiber), natural fiber can will be selected from
It uses, or can will be selected from two or more of them and be used in mixed way.Preferably, being used alone has the feature of environmental protection and change in size
The small natural fiber of rate.
As the natural fiber, jute (Jute) fiber, mestha (Kenaf) fiber, abaca can will be selected from
(Abaca) one of fiber, cocoanut fiber, wood-fibred use, or can will be selected from two or more of them and be used in mixed way.
