Description
Technical field
The present invention relates to a kind of plastics composite for pallet, belong to plastic material technical field.
Background technology
Pallet has another name called pallet, and pallet is that placement for collecting dress, stacking, carrying and transport is as the goods of unit load and the levelling bench arrangement of goods.As with the similar a kind of unit load devices of freight container, pallet has now been widely used in the fields such as production, transport, storage and circulation, is considered to one of two large key innovations in 20th century material flow industry.Pallet, as handling important in Logistics Operation process, storage and transportation equipment, supports the use and in modern logistics, is bringing into play huge effect with fork truck.The benefit that pallet brings to modern logistics industry is mainly reflected in: can realize blocking, standardization and the stdn of article packing, protection article, facilitate logistics and commodity-circulate,
At present, mostly adopt iron, common plastics or Wood-plastic material to make for the production of the material of pallet, and adopt pallet that polyethylene or acrylic plastering make for the advantage such as lightweight, cheapness, there is larger application space.As the making method of the disclosed a kind of continuous glass fibre reinforced thermoplastic plastics pallet of Chinese patent application (publication number: CN103214862A), it mainly adopts polypropylene, glass fibre, oxidation inhibitor and coupling agent raw material.Than common plastics pallet its have that mechanical strength is high, the strong and scrape resistant texts of excellent spring, non-deformability.But the pallet ubiquity resistance to fracture, the poor problem of shock resistance that adopt common plastics to make.
Summary of the invention
The present invention is directed to above problems of the prior art, a kind of plastics composite for pallet is provided, and the technical problem of solution is to realize the pallet that adopts plastics composite of the present invention to make to have resistance to fracture and the high effect of shock resistance, shore hardness and mechanical property.
The object of the invention is to be achieved by the following technical programs, a kind of plastics composite for pallet, this plastics composite is mainly made up of the weight part of following composition:
High density polyethylene(HDPE) or polypropylene: 70～85; : 2.0～3.0; Tetrafluoroethylene: 0.5～1.0; Ethylene-methacrylic acid copolymer: 2.0～5.0; Silane coupling agent: 0.5～0.8; Nanometer inorganic filler: 5.0～10; Synthetic rubber: 10～13; Fiber: 8.0～12; Fire retardant: 2.0～5.0; Antioxidant: 1.0～2.0.
The present invention is for the plastics composite of pallet, taking high density polyethylene(HDPE) or polypropylene as main raw, by adding and tetrafluoroethylene acting in conjunction to improve material in resistance to fracture and shock resistance, make the pallet that adopts plastics composite of the present invention to make there is higher resistance to fracture and shock resistance, but the inventor finds to add after, the shore hardness of matrix material can reduce, shore hardness can only reach 65 left and right, therefore, the present invention is by adding after ethylene-methacrylic acid copolymer and and tetrafluoroethylene compound use, find to there is synergy between them, make on the contrary the shore hardness of material be greatly improved, shore hardness can reach more than 90, and also can further improve resistance to fracture and shock resistance, more than resistance to impact shock can reach 10MPa, simultaneously, by adding after nanometer inorganic filler, synthetic rubber and silane coupling agent compound use, make overall mechanical property can reach requirement, as performances such as tensile strength, elongation at break, flexural strengths, by adding fire retardant and antioxidant, work-ing life and the flame retardant properties that can improve product, can also add the compositions such as pigment in above-mentioned plastics composite.
At the above-mentioned plastics composite for pallet, as preferably, this plastics composite is mainly made up of the weight part of following composition:
High density polyethylene(HDPE) or polypropylene: 75～80; : 2.2～2.8; Tetrafluoroethylene: 0.6～0.8; Ethylene-methacrylic acid copolymer: 3.0～4.0; Silane coupling agent: 0.6～0.7; Nanometer inorganic filler: 6.0～8.0; Synthetic rubber: 11～12; Fiber: 10～11; Fire retardant: 2.0～3.0; Antioxidant: 1.0～1.5.
At the above-mentioned plastics composite for pallet, as preferably, described silane coupling agent is selected from one or more in vinyl trichloro silane, vinyltriethoxysilane, vinyl three (2-methoxy ethoxy) silane, γ-methacryloxypropyl trimethoxy silane, methacryloxypropyl triethoxyl silane, vinyltrimethoxy silane, γ-glycidyl ether oxygen base propyl trimethoxy silicane and γ-mercapto propyl group dimethoxy silane.By adding silane coupling agent can improve plastics composite, can will between nanometer inorganic filler and the interface of organic materials, erect " molecular bridge ", make to improve the consistency between them, improve the performance of plastics composite and increase dispersiveness and the bonding strength of nanometer inorganic filler in high density polyethylene(HDPE) or polypropylene material.As further preferred, described silane coupling agent is the mixture of γ-methacryloxypropyl trimethoxy silane and vinyl three (2-methoxy ethoxy) silane, and the weight ratio of γ-methacryloxypropyl trimethoxy silane and vinyl three (2-methoxy ethoxy) silane is 1:2.4～2.8.
At the above-mentioned plastics composite for pallet, as preferably, described nanometer inorganic filler is selected from one or more in nano silicon, nano barium sulfate, nano titanium oxide or nano-calcium carbonate.Because pigment particles is easily reunited, form macrobead, affect quality product, the inventor finds to add nanometer BaSO in co-mixing system
4with nanometer CaCO
3after two kinds of inorganic nano-fillers, can improve the dispersiveness of pigment in plastics (plastic pallet), and the opacifying power of pigmenting power and goods.As further preferred, in described plastic pallet matrix material, also contain the pigment of 1.0～1.5 weight parts, described pigment is selected from P.R.48:2 pigment (pigment red 4 8:2), P.G.7 pigment (Phthalocyanine Green G) or P.Y180 pigment (Pigment Yellow 73 180), and described inorganic nano-filler is BaSO
4with nanometer CaCO
3mixture.As further preferably, 20%～30% nanometer CaCO for described pigment
3be coated processing, first by 20%～30% nanometer CaCO of pigment weight
3after mixing with pigment, add again in plastics composite, by by pigment and nanometer CaCO
3first carry out blend, can make nanometer CaCO
3be wrapped in the surface of pigment, thereby the color articles power and the opacifying power that make are improved greatly.
