Abstract
The invention relates to the technology field of material, in particular to a special material for the inner gaskets for covers of beverage-packing bottles, which is an alloy of polyolefin elastomer with polypropylene, polythene and additive, and is characterized in that the invention comprises by weight polyolefin elastomer 30-45%, polypropylene 15-30%, polythene 15-30%, viscosity-reducing agent 5-15% and slipping agent 1-5%. The invention essentially solves the technical problem associated with prior material that is of SEBS-based alloy, in which the oil in the oil-charged SEBS system is liable to seepage, hence the quality of the beverage is affected. The invention not only guarantees the health of the users, but also reduces the cost of the material.
Description
Technical field
The present invention relates to the material technology field, particularly a kind of special-purpose material for beverage packaging bottle cap.
Background technology
At home and abroad beverage packaging bottle cap substantially all adopts high speed compression moulding (1200 s'/minute) molding mode at present, and material therefor also is the blend based on SEBS (vinylbenzene, butadienecopolymer hydrogenation) of external major company exploitation substantially.Though this blend has good sealing function, because SEBS viscosity high needs could high-speed molding after oil-filled, and the oil in the SEBS system after oil-filled is easy to ooze out, thereby influences the quality of beverage; SEBS costs an arm and a leg simultaneously, has increased client's use cost.
Summary of the invention
The object of the present invention is to provide a kind of special-purpose material for beverage packaging bottle cap, mainly solve the blend that current material is based on SEBS, oil in the SEBS system after oil-filled is easy to ooze out, thereby influence the technical problem of the quality of beverage, not only ensure the healthy of user, and reduced the cost of material.
For solving the problems of the technologies described above, the present invention is achieved in that
A kind of special-purpose material for beverage packaging bottle cap, it adopts polyolefin elastomer material and polypropylene and polyethylene and additive blend, it is characterized in that: comprise polyolefin elastomer 30～45%, polypropylene 15～30%, polyethylene 15～30%, visbreaking agent 5～15% and slipping agent 1～5% according to weight percent.
By technique scheme, the present invention has following technique effect:
1, do not contain SEBS in the material system of the present invention, adopt the polyolefin elastomer material, have lower price.
2, do not contain SEBS in the material system of the present invention, can solve the problem that influences beverage quality of oozing out owing to oil in the SEBS system.
3, in the material system of the present invention, polyolefin elastomer system viscosity is lower than the SEBS system, can improve the shaping speed of bottle cap.
