The hot press composite plastic pallet is formed by hot pressing, and one or more layers of flax are filled in the middle of thermoplastic plastic, so that the problem of strength of the plastic pallet is solved, and the hot press composite plastic pallet has the advantages of light weight, high strength, long service life, low cost and the like, and is easy to recycle. The invention also provides a method for preparing the hot press composite plastic pallet.

Description

Hot pressing composite plastic pallet and preparation method thereof

[technical field]

The present invention relates to a kind of pallet and preparation method thereof, particularly a kind of hot pressing composite plastic pallet that cargo loading uses and preparation method thereof that is applied to.

[background technology]

Pallet uses for the ease of cargo handing, transportation, keeping and dispensing etc., by the load face of the some quantity article of carrying and the loading and unloading backing plate that the fork truck socket constitutes.Pallet mainly contains kinds such as paper pallet, wooden pallet, plastics pallet and metal stack plate at present.The paper pallet generally has special purpose, so development prospect is little; Metal stack plate then owing to price height, heaviness not easy-maintaining cause the atrophy gradually of its market; The wood pallet is dominate because price is relatively low, and the existing wooden pallet of China is to use fast growing wood mostly, but owing to intensity, the requirement of rigidity out of reach, shock-resistant grade is the out of reach index also, waste a large amount of timber, be unfavorable for environmental protection, therefore also must improvement.

[summary of the invention]

In view of this, the object of the present invention is to provide that a kind of intensity height, cost are low, the hot pressing composite plastic pallet that is beneficial to environmental protection and preparation method thereof.

For achieving the above object, a kind of hot pressing composite plastic of the present invention pallet is applied to cargo loading, it is characterized in that, this hot pressing composite plastic pallet comprises:

One first plastic layer;

One burlap layer is positioned on this first plastic layer, and this insensitive layer combines by hot pressing fusion mode with this first plastic layer; And

One second plastic layer is positioned on this burlap layer, and this second plastic layer combines by hot pressing fusion mode with this burlap layer.

The present invention also provides a kind of preparation method of hot pressing composite plastic pallet, and this hot pressing composite plastic pallet is applied to cargo loading, it is characterized in that this preparation method may further comprise the steps:

(a) burlap is soaked in the silane coupling agent 5-15 minute, takes out airing then;

(b) a ground floor thermoplastic plastic particle is put into a mould, on this ground floor thermoplastic plastic, spread the burlap of above-mentioned processing, then lay one second layer thermoplastic plastic particle on above-mentioned burlap;

(c) with this mould in 145 ℃-210 ℃ range of temperatures preheating 5-10 minute, adopt the pressure compression molding of 5MPA-20MPA simultaneously; And

(d) this mould is cooled off the hot pressing composite plastic pallet hardened forming that makes in the mould.

With respect to prior art, hot pressing composite plastic pallet of the present invention and preparation method thereof is in hot-forming mode, with thermoplastic plastic and burlap is composite material, by in the middle of thermoplastic plastic, filling one or more layers burlap, not only solve the strength problem of plastics pallets, had light weight, intensity height simultaneously, advantages such as the life-span is long, cost is low, easy recovery.

[description of drawings]

Fig. 1 illustrates the preparation scheme drawing of hot pressing composite plastic pallet of the present invention.

Fig. 2 illustrates the preparation method's of hot pressing composite plastic pallet of the present invention diagram of circuit.

[specific embodiment]

Below in conjunction with description of drawings and better embodiment the present invention is described in further detail:

Please refer to Fig. 1, the better embodiment of hot pressing composite plastic pallet of the present invention is as composite material with thermoplastic plastic and burlap.Hot pressing composite plastic pallet of the present invention comprises a ground floor thermoplastic plastic 10, a burlap layer 20 and a second layer thermoplastic plastic 30.Hot pressing composite plastic pallet of the present invention is by with this ground floor thermoplastic plastic 10, burlap layer 20 and second layer thermoplastic plastic 30 are put into mould 40 successively by hot-forming, promptly behind heating mould 40, toward the mould 40 interior plastic pellets that inject this ground floor thermoplastic plastic 10, spread the burlap of handling with silane coupling agent 20 above the ground floor thermoplastic plastic 10 at this then, with pressure ground floor thermoplastic plastic 10 and burlap 20 are fixed in the mould 30 again, the plastic pellet of second layer thermoplastic plastic 30 afterwards reinjects on this burlap 20, this ground floor thermoplastic plastic 10 of the timely chien shih of the melt temperature of control material again, burlap layer 20 and second layer thermoplastic plastic 30 molten adhere are hardened at last, can take out finished product after the cooling.

Wherein, this burlap 20 is a kind of clothes made from various fibre of flax for textile material fibers such as flax, ramie, jute, sisal hemp, abacas, has advantages such as intensity height, moisture absorption, heat conduction, permeability to air be good.This ground floor thermoplastic plastic 10 and second layer thermoplastic plastic 30 can be polyethylene, polypropylene, a kind of or its combination of polystyrene, polyvinylchloride, it has the characteristic of thermoplastic, hardening by cooling, deliquescing when promptly heating is so that flow, hardening is solidified during cooling, because this process is reversible, can carry out repeatedly, so the recyclable utilization of hot pressing composite plastic pallet of the present invention.

Wherein, with ground floor thermoplastic plastic 10 and between this flaxen fiber cloth 20 of multilayer can be set with second layer thermoplastic plastic 30, all lay has plastic pellet between every two-layer flaxen fiber cloth 20, and the shop layer angle of the burlap 20 between whenever two-layer is 45 °, the angle of longitude and latitude that is the burlap 20 of every adjacent two layers is respectively 45 °, so can help improving the intensity of material all directions.

Please refer to Fig. 2, the present invention also provides the preparation method's of this hot pressing composite plastic pallet concrete steps, and is as follows.

Step S1: burlap 20 is soaked in the silane coupling agent takes out airing after 5-15 minute, afterwards this burlap 20 is placed 85 ℃-95 ℃ baking oven baking 2-5 hour.Wherein, this silane coupling agent is that concentration is the silane ethanolic solution of 0.8%-2%.

Step S2: the plastic pellet of ground floor thermoplastic plastic 10 is put into mould 40, spread the burlap 20 of above-mentioned processing again at this above the ground floor thermoplastic plastic 10, afterwards the plastic pellet of lay second layer thermoplastic plastic 30 on above-mentioned burlap 20 again.

Step S3: in 145 ℃-210 ℃ range of temperatures, ground floor thermoplastic plastic 10 was combined in preheating 5-10 minute with burlap 20 with 30 fusions of second layer thermoplastic plastic on mould 40, adopt the pressure compression molding of 5MPA-20MPA simultaneously.

Step S4: this mould 40 is cooled off the hot pressing composite plastic pallet hardened forming that makes in the mould 40, take out finished product afterwards again.

Hot-forming composite plastic pallet of the present invention and preparation method thereof is a composite material with thermoplastic plastic and burlap, in the middle of thermoplastic plastic, fill one or more layers burlap by hot-forming, not only solved the strength problem of plastics pallets, have light weight, intensity height simultaneously, the life-span is long, cost is low, the advantage of easy recovery, this hot-forming composite plastic pallet also has tasteless nontoxic, acidproof, alkaline-resisting, withstanding corrosion, easily irrigation and disinfection, without putrefaction, advantage such as not combustion-supporting simultaneously.
