Description
Technical field
The present invention relates to bearing structure fields, and in particular to a kind of preparation method of the pallet with high bearing capacity.
Background technique
Pallet is well-known moveable platform-type bearing structure, and conventional pallet is generally plastics or wooden.But
Plastic pallet heavier-weight, price is higher, not readily portable；Although wood pallets have cheap, bearing capacity is weaker, makes
It is shorter with the service life, and wood pallets are non-watertight, there is a situation where mouldy rotten.
Therefore, it in order to solve the problems such as weight of weight present in normal tray, bearing capacity are weak, non-watertight, easily mouldy, needs
A kind of novel pallet preparation method is developed, has many advantages, such as that light-weight, bearing capacity is strong, waterproof novel to prepare
Pallet.
Summary of the invention
In view of this, the present invention provides a kind of preparation method of pallet with high bearing capacity, weight can be prepared
Gently, excellent, the cheap pallet with high bearing capacity of waterproof effect.
The preparation method of pallet provided by the invention with high bearing capacity, includes the following steps:
A, by EPS particle after prefoam, curing, it is filled into the shaping mould type chamber that pre- folding die slot does not mold completely
In, it is prepared into eps foam plate ontology；
B, the bottom surface to eps foam plate ontology and side carry out plastics processing, form EPS and are plasticized layer, then add PE film
Heat posted is attached to the upper surface of eps foam plate ontology, can be prepared by the pallet with high bearing capacity.
Further, in the step b, the concrete technology of plastics processing the following steps are included:
Cavity plate is warming up to 100~120 DEG C, the eps foam particle of the bottom surface and side that make eps foam plate ontology melts
For fluid state, fluid layer is formed, while EPS particles fuse, cavity plate is gradually mobile to punch-pin until molding, right after molding
Cavity plate is rapidly cooled, and so that the liquid EPS condensation of fluid layer is hardened can be obtained EPS plasticizing layer.
Further, the width of folding die slot is 9~18mm in advance.
Further, EPS plasticizing layer with a thickness of 0.3~0.6mm.
Further, in the step b, PE film is placed on punch-pin, then is molded, is passed through steam heating from punch-pin
Soften PE film and attaches to eps foam plate body upper surface.
Further, the PE film with a thickness of 0.2~0.4mm.
The present invention also provides prepared by a kind of preparation method using the pallet with high bearing capacity to have
The pallet of high bearing capacity, including eps foam plate ontology, the bottom surface and side of the eps foam plate ontology are to eps foam
The bottom surface of plate ontology and side carry out plastics processing and are formed by EPS plasticizing layer, and the upper surface of the eps foam plate ontology attaches
There is PE film.
Beneficial effects of the present invention:
The present invention provides a kind of preparation method of pallet with high bearing capacity, combines PE film by the plasticizing of EPS epidermis
It heats laminating, EPS plasticizing layer, eps foam plate and PE film is made to can be realized perfect combination, the pallet knot for being formed as one
Structure, to substantially increase the bearing capacity of pallet obtained；The maximum that pallet made from preparation method of the invention can be born
Dynamic loading is 800kg, and maximum static lotus is 1500kg；Meanwhile PE film is bonded by epidermis plastics processing combination upper surface, it is right
Eps foam plate ontology has carried out the booster action of limit fastening, can also be effectively prevented from deformation of products.In addition, of the invention
Pallet made from preparation method has also gathered the excellent properties of wood composite pallet and plastic pallet, since inner core is eps foam plate, weight
Compared to common pallet, mitigate significantly, since the tray surface has plasticizing layer and PE film, therefore the waterproof effect of pallet is excellent, together
When, the price of the pallet is cheap between wood composite pallet and plastic pallet.
