Problems solved by technology

[0002] As my country's rubber industry has been in line with international standards in recent years, tire processing plants have increasingly high quality requirements for rubber; ordinary inner membrane bags cannot be fused with rubber during rubber mixing, and inner membrane bags cannot melt, resulting in More impurities will affect the quality of rubber, resulting in a decline in rubber quality, which cannot meet the rubber quality requirements of tire processing plants; therefore, the rubber produced under existing conditions is expensive, complex in technology, and difficult to purchase raw materials

Abstract

The invention discloses an inner membrane bag for rubber processing and a preparation method thereof. The inner membrane bag for rubber processing is prepared from the following raw materials in parts by weight: 50 to 70 parts of low density polyethylene resin, 15 to 25 parts of low density polyethylene linear resin and 15 to 25 parts of high density polyethylene resin. The preparation method comprises the following steps: feeding the low density polyethylene resin, the low density polyethylene linear resin and the high density polyethylene resin into a high-speed mixing machine for mixing; transferring the mixture obtained by mixing into a double-screw extruder for plastifying extrusion, and performing water cooling and packaging, thereby obtaining the inner membrane bag. The inner membrane bag prepared through the preparation method is low in melting point which is about at 102 DEG C; a rubber plant can use the inner membrane bag conveniently; labor and time are saved, and the quality of rubber can be improved; the inner membrane bag is safe and reliable; the rubber prepared from the inner membrane bag with low melting point has the characteristics of a conventional product and is relatively high in tensile strength and can be widely applied to the field of production of tires.
