Abstract
The invention relates to a high-toughness and high-brightness polyethylene bottle cap and a manufacturing method thereof. The manufacturing method comprises the following steps of: dispersing a material consisting of 100 weight parts of polyethylene, 0.5 to 5 weight parts of color concentrate, 5 to 10 weight parts of toughening agent, 1 to 5 weight parts of brightening agent and 5 to 10 weight parts of aid in a high-speed kneading machine; and performing injection molding on the dispersed material so as to obtain the bottle cap. The impact strength of the material is more than or equal to 50 kJ/m<2>, yield strength is more than or equal to 10 MPa and glossiness is more than or equal to 80 percent.
Description
One, technical field
The invention belongs to the sealing material technology of preparing, particularly a kind of high tenacity, high bright polyethylene bottle cap and novel preparation method thereof.
Two, background technology
Bottle cap is food and the important ring of drink packing, it also is the place that the human consumer contacts with product at first, bottle cap has the characteristic that keeps product stopping property and stabilizing quality, also has the function of antitheft unlatching and security aspect, therefore, bottle cap is a food, the drink industry, wine, chemical industry, the upstream industry of pharmacy industry is the key product of bottle container packing.
Plastic bottle closure is an integral part of bottle cap, and generally the plastics of Shi Yonging have polypropylene (PP), polyethylene (polyethylene), polyacrylonitrile-butadiene-styrene (ABS).Patent 1616311 discloses a kind of bottle cap and preparation method thereof, relates to polypropylene and polyethylene compound material.
At present, domestic vinyon bottle cap manufacturing enterprise level is uneven, often exists snappiness poor, no luminance brightness, the more high defective of energy consumption.
Three, summary of the invention
The present invention aims to provide a kind of high tenacity, high bright polyethylene bottle cap, and technical problem to be solved is that polyethylene is carried out modification, to improve the snappiness and the luminance brightness of polyethylene bottle cap.
It is composite modified that the present invention adopts inorganic nano-particle and vegetables oil that polyethylene is carried out, specifically, and the bottle cap of the materials processing that this high tenacity, high bright polyethylene bottle cap are made up of each component of following weight part:
100 parts of polyethylene
0.1～5 part of colour batch
5～10 parts of auxiliary agents
5～10 parts of toughner
1～5 part of brightening agent.
Described colour batch is the polyethylene color masterbatch, pigment content 30～50%.
Described auxiliary agent is selected from epoxy soybean oil, arborvitae wet goods.
Described toughner is selected from nanometer SiO
2, nano-powder such as lime carbonate.
Described brightening agent is selected from oxidized polyethlene wax, Microcrystalline Wax.
The preparation method of this high tenacity, high bright polyethylene bottle cap comprises high speed dispersion and injection moulding.Here it is at first disperses injection moulding then with polyethylene, colour batch, toughner, brightening agent and the auxiliary agent of proportional quantity at the high speed kneader.
High speed kneader rotating speed 1000～1500rpm, jitter time 5～10min.
120～150 ℃ of injection moulding temperature, pressure 5～8MPa.
Matrix material shock strength 〉=the 50kJ/m2 that adds the cost bottle cap, yield strength 〉=10MPa, glossiness 〉=80%.
High tenacity, the high bright polyethylene bottle cap of the present invention's preparation, high comprehensive performance, cost performance height.Advantage of the present invention is mainly reflected in:
1, adopt inorganic nano-particle and vegetables oil that polyethylene is carried out toughness reinforcing and modification.
2, injection moulding temperature is low.
3, production technique is simply clean, and product stability is good, and is with low cost.
