Abstract
The invention relates to a reusable tire isolating membrane. The reusable tire isolating membrane is characterized by comprising the following components in parts by weight: 50-100 parts of high density polyethylene and 0-50 parts of metallocene polyethylene and ethlene bistearic amide, wherein 0.5kg-2.5kg of ethlene bistearic amide is added into each 100kg of metallocene polyethylene and ethlene bistearic amide; the thickness of the reusable tire isolating membrane is 0.3mm-0.75mm. The reusable tire isolating membrane is prepared by carrying out once forming on high density polyethylene, metallocene polyethylene and ethlene bistearic amide in tape casting equipment; a tape casting steel roll of the tape casting equipment is carved with patterns, so that the patterns can be once formed on the surface of isolating membrane. According to the reusable tire isolating membrane, the performance of the isolating membrane is improved, and the number of repeated use is increased.
Description
Technical field
The present invention relates to a kind of reusable tire barrier film, belong to radial tyre production technical field.
Background technology
Tire barrier film is used for a kind of subsidiary material in tire production process, and effect is sheet rubber before making last sulfuration and air insulated, reaches effect that is fresh-keeping, dust-proof, shading.Existing common tire barrier film adopts polyethylene film mostly, when polyethylene film and sheet rubber are peeled off, there will be the phenomenons such as distortion, fold, perforation, thus can only single use.
In prior art, tire barrier film is that film blowing device is produced, and the intrinsic feature of its film blowing device causes the thickness of film to be generally less than 0.3mm.The barrier film that film blowing device is produced is light film (surface is without any decorative pattern), as barrier film needs decorative pattern need carry out embossing process on embossing machine equipment.In addition, the stripping performance of existing barrier film mainly uses amine hydroxybenzene to realize, but the fusing point 72-77 DEG C of amine hydroxybenzene, fusing point is on the low side, because the processing temperature of rubber is higher, amine hydroxybenzene can be there is and move to phenomenon on rubber, cause the pollution of rubber item.Use the barrier film of amine hydroxybenzene surface to have a kind of greasy sensation, the steel wire calendaring operation of tire production there will be tension force abnormal, the phenomenons such as rolling dislocation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of reusable tire barrier film is provided, improve the performance of barrier film, add iterative cycles access times.
According to technical scheme provided by the invention, described reusable tire barrier film, it is characterized in that, comprise following component: the high density polyethylene(HDPE) of 50 ~ 100 weight parts, the metallocene PE of 0 ~ 50 weight part and ethylene bis stearic amide, in the high density polyethylene(HDPE) of every 100 kilograms and metallocene PE, add 0.5 ~ 2.5 kilogram of ethylene bis stearic amide.
Further, the thickness of described barrier film is 0.3 ~ 0.75mm.
Further, the once shaped in salivation equipment of described high density polyethylene(HDPE), metallocene PE and ethylene bis stearic amide, obtains barrier film.
Further, the salivation steel rider of described salivation equipment is carved with decorative pattern, thus forms decorative pattern in barrier film surface once shaped.
The present invention has the following advantages: (1) the present invention uses high-density alkene ethene, for barrier film provides rigidity, toughness, makes film not volatility, and metallocene PE is that barrier film provides higher tear strength and toughness, makes barrier film not fragile; (2) after the present invention uses ethylene bis stearic amide, due to its high-melting-point 144-146 DEG C, add in tire production and transport phenomena can not occur man-hour, avoid the generation of pollution, the barrier film surface using ethylene bis stearic amide to do stripper does not have greasy sensation, the steel wire calendaring operation of tire production there will not be tension force abnormal, the phenomenons such as rolling dislocation, can waste product be reduced, enhance productivity; (3) number of times of reusing of barrier film of the present invention is greater than 50 times; (4) salivate on steel rider and be carved with decorative pattern, the decorative pattern once shaped on barrier film surface can be made, do not need to carry out embossing process on emebosser; Also can adopt smooth salivation steel rider, thus the barrier film obtained surface is without decorative pattern.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
