Description
Technical Field
The utility model belongs to the technical field of the board is moulded to calcium, concretely relates to board is moulded to compound calcium.
Background
The calcium-plastic board is made up by using high-density polyethylene (HDPE) as main raw material, using calcium carbonate as filling material and adding various assistants, rolling and hot-sticking them to obtain the invented product. The calcium plastic board has the characteristics and advantages of light weight, high strength, moisture resistance, water resistance, good toughness, difficult breakage, no worm damage, no pollution, environmental protection, repeated recycling and the like, and is an outer packaging product which is mainly popularized internationally. However, the surface of the existing calcium plastic board is easy to scratch and damage during transportation or storage, and the packaging box made of the calcium plastic board is not suitable for packaging and storing fragile products because the calcium plastic board has the characteristics of hardness and high strength.
Disclosure of Invention
The utility model aims at the not enough of above-mentioned prior art existence, the utility model aims at providing a board is moulded to compound calcium, its surface has covered the cotton inoxidizing coating of pearl through hot pressing tectorial membrane technology for this board is moulded to compound calcium can avoid the scraping damage, and its soft top layer has better shock attenuation nature, is fit for fragile article packing and deposits.
In order to achieve the above purpose, the utility model adopts the technical scheme that.
The utility model provides a board is moulded to compound calcium, includes that upper calcium moulds the slab and the slab is moulded to lower floor's calcium, is provided with the board core between upper calcium moulds the slab and the slab is moulded to lower floor's calcium, the upper and lower two sides of board core pass through hot-pressing bonding with upper calcium moulds the slab and the slab is moulded to lower floor's calcium respectively, the upper surface of upper calcium moulds the slab and/or the lower surface of the slab is moulded to lower floor's calcium covers and has closed EPE pearl cotton layer.
Preferably, the outer side surface of the EPE pearl wool layer is further coated with an aluminum foil layer or an aluminum-plated film layer.
Furthermore, the board core is a corrugated board core or a honeycomb board core formed by pressing calcium-plastic board sheets.
Preferably, the EPE pearl wool layer is combined with the upper layer calcium-plastic plate and/or the lower layer calcium-plastic plate in a hot-pressing manner.
After the technical scheme is adopted, compared with the prior art, the utility model the advantage that has is.
Compared with the prior art, the utility model discloses a calcium is moulded board surface and is covered and to have EPE pearl cotton layer, and EPE pearl cotton, also known as polyethylene foam cotton are non-crosslinked obturator structure, are the packaging material of a novel environmental protection. The low-density polyethylene foam plastic is formed by innumerable independent bubbles generated by physically foaming low-density polyethylene, overcomes the defects of fragility, deformation and poor recovery of common foam rubber, has the advantages of water resistance, moisture resistance, shock resistance, sound insulation, heat preservation, good plastic property, strong toughness, cyclic reconstruction, environmental protection, strong impact resistance and the like, also has good chemical resistance, and is an ideal substitute of the traditional packaging material. EPE pearl cotton is as the top layer of calcium plastic board, can avoid calcium plastic board surface scraping damage, and EPE pearl cotton has better compliance simultaneously for this compound calcium plastic board has better shock attenuation nature, thereby the calcium plastic case that it made is suitable for fragile packing to be deposited.

Fig. 1 is a schematic structural diagram of a first embodiment of the present invention.
Fig. 2 is a schematic structural diagram of a second embodiment of the present invention.
Fig. 3 is a schematic structural diagram of a third embodiment of the present invention.
In the figure, 1 is an upper layer calcium-plastic plate, 2 is a lower layer calcium-plastic plate, 3 is a corrugated plate core, 4 is an EPE pearl cotton layer, 5 is an aluminum foil layer, and 6 is a honeycomb plate core.
Detailed Description
The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.
In one embodiment, referring to fig. 1, a composite calcium-plastic board comprises an upper calcium-plastic board sheet 1 and a lower calcium-plastic board sheet 2, wherein a board core is arranged between the upper calcium-plastic board sheet 1 and the lower calcium-plastic board sheet 2, the upper surface and the lower surface of the board core are respectively bonded with the upper calcium-plastic board sheet 1 and the lower calcium-plastic board sheet 2 through hot pressing, and an EPE pearl wool layer 4 is covered on the upper surface of the upper calcium-plastic board sheet 1. The board core is a corrugated board core 3 formed by pressing a calcium-plastic board, the EPE pearl cotton layer 4 and the upper calcium-plastic board 1 are combined in a hot pressing mode, hot pressing, namely hot melting and rolling, is more than two phases of thermoplastic materials, and is pressed and plasticized between rotating rollers, so that a continuous film or sheet is manufactured.
In the second embodiment, referring to fig. 2, the difference between the first embodiment and the second embodiment is that an aluminum foil layer 5 is further coated on the outer surface of the EPE pearl wool layer 4, and the aluminum foil layer 5 may be an aluminum-plated film layer. The aluminum foil layer 5 or the aluminum-plated film layer can be coated with the EPE pearl cotton layer 4 by adopting a hot pressing process or can be adhered by adopting glue, the EPE pearl cotton layer 4 has better heat preservation performance, and the aluminum foil layer 5 has better anti-infrared and ultraviolet capabilities, so that the composite calcium plastic plate can be suitable for packaging articles in the fields of refrigeration, storage and transportation and the like.
Third embodiment, referring to fig. 3, the difference between the first embodiment and the second embodiment is that the board core is a honeycomb board core 6 formed by compression molding of calcium-plastic board sheets, and the upper surface of the upper layer calcium-plastic board sheet 1 and the lower surface of the lower layer calcium-plastic board 2 are both covered with EPE pearl cotton layers 4. In the first embodiment, the upper and lower surfaces of the composite calcium plastic board of the corrugated board core 3 may be covered with the EPE pearl cotton layer 4.
The above is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the claims of the present invention.
