Embodiment Construction
[0013] attached figure 1 It is a schematic diagram of the manufacturing method of the fresh-keeping isolation layer of the present invention. The woven wire mesh 3 of the present invention is used as the middle layer of the fresh-keeping isolation layer which can be recycled in the preparation of rubber tires, and as the skeleton of the fresh-keeping isolation layer, it is placed on the salivating die heads 1 and 2. in the middle of the mouth. Two salivating dies 1,2 simultaneously drool and melt the polyolefin surface material 4, and the braided wire mesh 3 guided by the guide roller 10 in the middle of the salivating dies 1 and 2 also moves to the two pressure rollers 5 and 6 at the same time. The pressure rollers 5 and 6 with the same rotating speed, opposite rotation, and substantially parallel axis centers are rolled and pressed together next time, and are cooled and flattened by the cooling roller 8 to form a fresh-keeping isolation layer 7 with a woven wire mesh 4 . Be...

The invention relates to a method for manufacturing fresh-keeping isolating layers circularly used for rubber tire preparation. The method comprises the steps of: simultaneously drooling fused polyolefins surface materials by utilizing two drooling die heads, compositing a knitted wire mesh in the middle, performing hot-pressing compositing by utilizing press rolls, and solidifying so as to obtain the fresh-keeping isolating layers, wherein the press rolls and cooling rolls are synchronous in the rotating speeds and the thickness of the fresh-keeping isolating layers can be controlled through adjusting a gap between the two adjacent press rolls and the rotating speeds of the press rolls and the cooling rolls; the press rolls and the cooling rolls are hollow rolls; and a surface cooling effect can be provided through introducing water in a circulating manner to ensure that the fresh-keeping isolating layers can be rapidly solidified and formed. According to the method disclosed by the invention, the fresh-keeping isolating layers can be formed by one step and the three-layer fusion fastness is extremely high so as to enable the three layers are similar to a whole; the inherent characteristics of the original fresh-keeping film is kept and the fresh-keeping isolating layers can be recycled due to the knitted wire mesh integrated in the middle; and as the fresh-keeping isolating layers are formed by one step, and no bonding material or bonding process is required among the surface layers, the fresh-keeping isolating layers are low in manufacturing cost and suitable for mass production. The recyclable rubber tire fresh-keeping isolating layers produced by using the method can be repeatedly used for more than 50 times.
Description
technical field [0001] The invention belongs to a polyolefin film composite manufacturing method technology, and specifically refers to a polyolefin film composite layer manufacturing method that can be recycled and used for fresh-keeping and isolation of rubber sheets in the rubber tire preparation process. technical background [0002] In the tire molding process of rubber tires before vulcanization, the tire green body is formed by bonding several layers of rubber sheets. In order to avoid the oxidation and pollution of the rubber sheet in contact with air, other gases and sundries, the coating and isolation material of the rubber sheet currently in use is polyethylene film. After the rubber sheets are bonded, the polyethylene cling film's job is done and it's discarded. Therefore, the reason why polyethylene cling film can only be used once is that when the polyethylene cling film is peeled off from the rubber sheet, the polyethylene cling film will be deformed, folded,...
