Abstract
The embodiment of the invention discloses a kind of Teflon shields and the preparation method and application thereof, the preparation method of the Teflon shield, raw material including choosing warp thread and weft yarn, plain weave interlaced plies are made in warp thread and weft yarns, polyurethane sizing is coated in plain weave interlaced plies later, the Teflon shield is made.Teflon shield provided in an embodiment of the present invention is interweaved using warp, latitude raw materials of chemical fibres plain weave, is combined later using the sizing of high-temperature coating polyurethane, to solve glutinous viscous phenomenon.Fresh keeping property is more than 15 days or more simultaneously, decline the original viscosity of rubber will not, and tensile capacity is also relatively strong, the appearance of Teflon shield thoroughly solve the problems, such as that other products encounter in steel wire calendaring link it is glutinous glue, fresh keeping property it is poor.To subtract the waste of sheet rubber, the quality of product ensure that.
Description
Technical field
The present embodiments relate to tire manufacturing techniques fields, and in particular to a kind of Teflon shield and preparation method thereof with
Using.
Background technique
With auto industry emergence and flourish, people are higher and higher to the quality requirement of rubber tyre.In tire
In manufacturing process, separate the rubber mass placed in rolls usually using shield.But since rubber weight is big, to the property of shield
It can have higher requirements, only the performance of shield is high, can prevent the rubber products such as carcass from will not deform in coiled place.
Tire plant carries out the curling of the isolation between rubber in initial production tire, with snakeskin bag.But in use, snakeskin bag can hold
Easily there is phenomena such as glutinous viscous, fresh keeping property is poor, the service life is short to be easily broken, this just leverages the quality of rubber, causes rubber
Waste, while also will affect the quality of tire.With the demand of tire plant, textile industry starts to concentrate on studies, with and produce
First shield-polypropylene fibre shield is gone out.
Although polypropylene fibre shield is more quite a lot of than the effect of snakeskin bag, it still can not solve shield and exist on steel wire calendaring position
It is glutinous viscous, the problem of fresh keeping property difference.
Summary of the invention
For this purpose, the embodiment of the present invention provides a kind of Teflon shield and the preparation method and application thereof, to solve the prior art
Middle shield there is a problem of glutinous viscous, fresh keeping property difference on steel wire calendaring position.
To achieve the goals above, embodiments of the present invention provide the following technical solutions:
In the first aspect of embodiments of the present invention, a kind of preparation method of Teflon shield is provided, including with
Lower step:
Step 1: choosing the raw material of warp thread and weft yarn, warp thread and weft yarn plain weave is interweaved, plain weave interlaced plies are made, it is spare；
Step 2: coating polyurethane sizing in plain weave interlaced plies, the Teflon shield is made.
In one embodiment of the invention, the step two includes that poly- ammonia is coated in plain weave interlaced plies under high temperature
Ester obtains the Teflon shield after being cooled to room temperature.
In one embodiment of the invention, the step two includes that poly- ammonia is coated in plain weave interlaced plies under high temperature
Ester obtains the Teflon shield after being cooled to room temperature.
In one embodiment of the invention, the high temperature refers to 100-200 DEG C.
In one embodiment of the invention, the raw material of the warp thread and weft yarn is chemical fibre.
In the second aspect of embodiments of the present invention, provide a kind of Teflon shield, the Teflon shield by
Any one the method is made.
In one embodiment of the invention, the Teflon shield includes plain weave interlaced plies and interweaves coated in plain weave
Polyurethane on layer, the plain weave interlaced plies are formed by warp thread and weft yarns.
In the third aspect of embodiments of the present invention, any one of provide Teflon shield made from the method in
Application in rubber tyre production.
Embodiment according to the present invention, have the advantages that the embodiment of the invention discloses a kind of Teflon shield and
Preparation method and application, the Teflon shield is interweaved using warp, latitude raw materials of chemical fibres plain weave, poly- using high-temperature coating later
Urethane sizing is combined, to solve glutinous viscous phenomenon.Fresh keeping property is more than 15 days or more simultaneously, makes the original viscosity of rubber
It will not decline, tensile capacity is also relatively strong, and the appearance of Teflon shield thoroughly solves other products and meets in steel wire calendaring link
Glutinous viscous, fresh keeping property difference the problem arrived.To subtract the waste of sheet rubber, the quality of product ensure that.
Detailed description of the invention
It, below will be to embodiment party in order to illustrate more clearly of embodiments of the present invention or technical solution in the prior art
Formula or attached drawing needed to be used in the description of the prior art are briefly described.It should be evident that the accompanying drawings in the following description is only
It is merely exemplary, it for those of ordinary skill in the art, without creative efforts, can also basis
The attached drawing of offer, which is extended, obtains other implementation attached drawings.
