Abstract
The present invention relates to the manufacture technology of rubber tyre, and is especially preserving isolation plastic film for rubber tyre. Technologically, the isolation plastic film consists of low density polyethylene 29-92 wt%, high density polyethylene 6-70 wt%, linear density polyethylene 0-25 wt% and amido oleate 0.006-0.15 wt%. The isolation plastic film is used in preserving and isolating rubber sheet during the rubber tyre producing process and can stripped easily from rubber sheet, resulting in high quality of rubber tyre and lowered production cost.
Description
Technical field
The present invention relates to the rubber tyre manufacturing technology, specifically a kind of fresh-keeping barrier film of plastics of making rubber tyre that is exclusively used in.
Background technology
Fresh-keeping barrier film is mainly used in all steel, semi-steel radial tire factory in producing the tire process, and rubber is isolated with fresh-keeping.Tire plant is after mixing natural gum refining glue with various industrial chemicals, rubber and steel wire calendering is bonding, and its work in-process suitably to be deposited for some time (usually greater than 48 hours), during this period, just exist the isolation between every layer of sheet rubber and how to guarantee the fresh-keeping problem of sheet rubber.
Natural rubber will be isolated fully with air and sunlight, otherwise can produce a kind of zone of oxidation on the surface of rubber mixed refining glue with various industrial chemicals after, and this zone of oxidation can have influence on the work-ing life of tire and in the running on expressway process safe.Adopt polyethylene to isolate preservative film (or claiming fresh-keeping barrier film), just can address this problem well.Because after the calendering of rubber and steel wire is bonding in a flash, polyethylene is isolated preservative film and just promptly sheet rubber is carried out upper-lower seal, itself and sunlight and air are isolated rapidly,, make it after producing tire to reach fresh-keeping effect, improve the bonding effect in every layer of sheet rubber of tire greatly, be difficult for delamination, in tire is run at high speed process, because its good wear-resisting, resistance to elevated temperatures, and situations such as difficult generation automobile flat tire, the security that improves automobile.
Mainly (LDPEO, linear low density polyethylene (LLDPE) etc. become to be grouped into existing fresh-keeping barrier film by high density polyethylene(HDPE) (HDPE), new LDPE (film grade), this barrier film can play certain fresh-keeping and buffer action, but there are many problems peeling off of sheet rubber and barrier film, often occur in process of production being difficult to peel off and make sheet rubber distortion, perhaps simply can't peel off.Have influence on the ordinary production of tire plant.
Summary of the invention
Of the present invention, purpose is to provide a kind of rubber fresh-keeping barrier film of plastics, this barrier film can be effectively to the sheet rubber in the tire production process carry out fresh-keeping with isolate, and peel off from sheet rubber easily, thus improved tire quality, reduced production cost.
Its main technical schemes is: this barrier film is mainly by new LDPE (film grade) 29～92%, high density polyethylene(HDPE) 6～70%, linear low density polyethylene 0～25%, amine hydroxybenzene 0.006～0.15% is formed, the unit of this paper is weight percentage, and used production method is with original identical.
Wherein new LDPE (film grade) is one of main raw material of rubber tyre usefulness polyethylene barrier film, and its moulding processability and flexibility are all relatively good, and can reduce the softening temperature of polyethylene barrier film; High density polyethylene(HDPE) also is one of main raw material of rubber tyre usefulness barrier film, and this material has higher rigidity and toughness, and the good mechanical performance can increase and isolate film strength and spreading; Linear low density polyethylene has good tear strength, tensile strength and hot close property, can increase polyethylene and isolate film strength and stretching force; Amine hydroxybenzene can increase the smooth property of the fresh-keeping barrier film of polyethylene, and barrier film is stripped down on the sheet rubber easily.
Advantage of the present invention is owing to increased a spot of amine hydroxybenzene in original fresh-keeping barrier film, in tire production process, the isolation and the freshening effect that have kept original barrier film, has the good effect of peeling off again, the problems such as sheet rubber distortion that may cause in the stripping process have been avoided, the production efficiency of tire plant is greatly improved, has saved great amount of manpower and material resources, reduced production cost.

Embodiment four
New LDPE (film grade) 59.994%, high density polyethylene(HDPE) 40%, linear low density polyethylene 0%, amine hydroxybenzene 0.006%.The barrier film intensity height of this composition, neither too hard, nor too soft, easily and sheet rubber bonding, but it is general to peel off effect.
Embodiment five
New LDPE (film grade) 68.85%, high density polyethylene(HDPE) 6%, linear low density polyethylene 25%, amine hydroxybenzene 0.15%.The barrier film intensity height of this composition, good percentage elongation, easy delamination when bonding with sheet rubber, but peel off effective.
Embodiment six
New LDPE (film grade) 70%, high density polyethylene(HDPE) 20%, linear low density polyethylene 9,94%, amine hydroxybenzene 0.06%.The barrier film intensity height of this composition, flexibility are good, easily and sheet rubber bonding, it is also relatively good to peel off effect.
Embodiment seven
New LDPE (film grade) 80%, high density polyethylene(HDPE) 15%, linear low density polyethylene 4.92%, amine hydroxybenzene 0.08%.The barrier film intensity height of this composition, flexibility are good, and softening temperature is low, easily and sheet rubber bonding, peel off effect.
The operating process of the foregoing description is: under normal pressure, between 5～40 ℃ of temperature, new LDPE (film grade), high density polyethylene(HDPE), linear low density polyethylene, amine hydroxybenzene are added in the stirrer successively, stir and got final product in 15 minutes.
