Abstract
The invention relates to a manufacturing method of a plastic tray, which comprises the following steps: adding maleic anhydride grafted polyethylene into waste plastic according to the proportion of components in the plastic after testing of the waste plastic; adding polyoctene/polyethylene elastomer at a following proportion (by weight): 100G of waste plastic, 5-7G of maleic anhydride grafted polyethylene and 15-18G of polyoctene/polyethylene elastomer; fully mixing at high temperature; granulating; and carrying out injection molding to obtain the product. The invention has the beneficial effects that the washing resistance and low-temperature shock resistance of PP (polystyrene) can be improved.
Description
Technical field
The present invention relates to a kind of plastic pallet, particularly a kind of method of manufacture of plastic pallet.
Background technology
Plastic pallet is a kind of underbed device that is used in the storage.
Waste or used plastics is made pallet owing to receive reasons such as its working life, working conditions (sunlight is exposed to the sun) and acid and alkali corrosion, causes the impact strength of plastics and toughness to reduce, and makes the plastic waste utility value not high; So adopted the conventional processing means in the prior art usually: burn and sanitary landfill method.
The material that how to make waste or used plastics can become plastic pallet is that the technician will consider the technical problem that solves.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of method of manufacture of plastic pallet, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention realizes through following steps:
After plastic waste detected, according to recording the plastic component content ratio, the interpolation maleic anhydride connect and gathers second (PE-g-MAH) in plastic waste; And then add and to gather octene/ethylene elastomer (POE), adding proportion (weight): plastic waste 100G, addition are that the maleic anhydride of 5G～7G connects and gathers second, and 15G～18G gathers octene/ethylene elastomer;
High temperature is fully fused;
Granulation;
Injecting products.
Compared with prior art, the invention has the beneficial effects as follows: can improve anti-intensity and the low-temperature impact resistance gone out of PP.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail:
In modifying waste plastic; It more is physically modified; Through the blending and modifying of superpolymer and superpolymer, improve the inherent characteristics of some superpolymer, in PP, add the PE-g-MAH compatilizer; Add POE (gathering octene/ethylene elastomer) then, can improve PP impact strength and low-temperature impact resistance.
Above-mentioned gather octene/ethylene elastomer and maleic anhydride connect gather on the second market all on sale.
High temperature in the step of the present invention is fully fused, granulation and injecting products are identical with the step of prior art.
Lift a preferred embodiment below, the present invention intactly is described;
Embodiment 1
After plastic waste detected, according to recording the plastic component content ratio, the interpolation maleic anhydride connect and gathers second (PE-g-MAH) in plastic waste; And then add and to gather octene/ethylene elastomer (POE), adding proportion (weight): plastic waste 100G, addition are that the maleic anhydride of 5G connects and gathers second, and 15G gathers octene/ethylene elastomer;
High temperature is fully fused;
Granulation;
Injecting products.
Embodiment 2
After plastic waste detected, according to recording the plastic component content ratio, the interpolation maleic anhydride connect and gathers second (PE-g-MAH) in plastic waste; And then add and to gather octene/ethylene elastomer (POE), adding proportion (weight): plastic waste 100G, addition are that the maleic anhydride of 7G connects and gathers second, and 18G gathers octene/ethylene elastomer;
High temperature is fully fused;
Granulation;
Injecting products.
Embodiment 3
After plastic waste detected, according to recording the plastic component content ratio, the interpolation maleic anhydride connect and gathers second (PE-g-MAH) in plastic waste; And then add and to gather octene/ethylene elastomer (POE), adding proportion (weight): plastic waste 100G, addition are that the maleic anhydride of 5G connects and gathers second, and 18G gathers octene/ethylene elastomer;
High temperature is fully fused;
Granulation;
Injecting products.
2.5 meters fall down test breakage rates of pallet of being produced before plastic waste is unmodified are 100%, and 2.5 meters fall down test breakage rates of the pallet of being produced after the modification are 5%.
The 20KG pallet dynamic load of being produced before plastic waste is unmodified is: 0.6T, and static load is: 3T; The 20KG pallet dynamic load that the unmodified back of plastic waste is produced is: 1.5T, static load is: 6T.
After modification to waste or used plastics, improved resource utilization, the plastics cost after the modification reduces greatly.
Though more than described this improved embodiment, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from this improved principle and essence, can make numerous variations or modification to these embodiments.Therefore, this improved protection domain is limited appended claims.
