2) Short-term anti-static, the surface resistivity can generally reach 10^9-10^11Ω, and its main component is surfactant. Due to the hydrogen bond, the surface of the lining barrel will form a film when it contacts with air. The film has the function of conducting current, but its disadvantage is that the conductivity value is very unstable, which is related to the air humidity. Specifically, the anti-static level is different under different air humidity, and the process is complicated, requiring secondary heating and secondary stretching

Abstract
The invention discloses a lining barrel and a preparation process of the lining barrel, belonging to the technical field of production of plastic lining barrels. The lining barrel comprises 40%-60% of conductive master batch, 20%-30% of polypropylene and 20%-30% of polyethylene. The preparation process of the lining barrel comprises the steps of mixing and stirring of the raw materials, heating and extruding, calendering, heating and forming, plate transmission heating, mold forming and the like. The lining barrel is good in overall structural property, light in weight and free of toxicity; a raw material ratio and a part of the preparation process can be flexibly adjusted according to the requirements of customers, and then anti-static lining barrel products with different properties can be obtained. According to the preparation process of the lining barrel, a plate can be subjected to punch forming at a time through a machine mold, and then an intact lining barrel can be directly produced; and meanwhile, intermittent semi-automatic operation can be achieved under mechanical conditions,so production integration is achieved, a preparation technology is simple and convenient, production efficiency is high, and labor cost is low.
Description
technical field [0001] The invention relates to the technical field of production of plastic lined barrels, in particular to a lined barrel and a preparation process thereof. Background technique [0002] The liner barrel is a disposable plastic barrel liner that is set in the raw material barrel and can make the raw material barrel reusable. It is mostly used for storage and transportation of various liquids and chemical raw materials. It is not fragile and rust-free. , light weight and other characteristics, the main purpose of the existence of plastic lined barrels is to reduce the cost of using raw material barrels, and solve the problems of environmental protection and waste of resources after use of raw material barrels. However, due to the inevitable friction between the outer wall of the liner bag body and the packaging barrel during transportation to generate static electricity, physical antistatic treatment is usually performed between the outer wall of the inner l...
