Technical Field
The invention relates to the technical field of winding film processing, in particular to a high-tensile winding film and a processing technology thereof.
Background
The winding film is called as a stretching film, the winding film compactly and fixedly bundles products into a unit by means of the ultra-strong winding force and retractility of the film, the products are not easy to loosen and separate, the packaging requirements of people on the winding film are increasingly large along with the continuous development of the society, and the winding film is widely applied to industries such as foreign trade outlets, bottle making and can making, paper making, hardware and electric appliances, plastics, chemical engineering, building materials, agricultural products, fresh food, flowers and the like. The requirement for the winding film is increasing, when sharp objects are wound on the common winding film, the winding film is easy to scratch and break, meanwhile, the common winding film is general in stretch resistance and corrosion resistance, the winding film is easy to loose after the objects are bundled for a long time, the bundled objects are easy to scatter, the operation personnel are required to perform winding operation again, the working strength of the operation personnel is improved, and the working efficiency is reduced.
Disclosure of Invention
The invention aims to provide a high-stretch winding film and a processing technology thereof, so as to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: a high-tension winding film comprises 40 parts of polyisobutylene, 50 parts of very low density polyethylene, 60 parts of linear low density polyethylene, 50 parts of metallocene polyethylene, 30 parts of polyvinyl chloride, 20 parts of plasticizer, 30 parts of polypropylene, 40 parts of polyethylene terephthalate, 10 parts of antistatic agent, 15 parts of anti-blocking agent and 15 parts of additive;
a processing technology of a high-stretch winding film comprises the steps of firstly, preparing raw materials; step two, mixing materials; step three, high-temperature smelting; step four, co-extruding and film blowing; step five, stretching; step six, cooling and rolling;
in the first step, the worker selects polyisobutylene, very low density polyethylene, linear low density polyethylene, metallocene polyethylene, polyvinyl chloride, plasticizer, polypropylene, polyethylene terephthalate, antistatic agent, antiblocking agent and additive raw materials which meet the requirements according to the production requirements;
in the second step, the worker introduces the selected raw materials of polyisobutylene, very low density polyethylene, linear low density polyethylene, metallocene polyethylene, polyvinyl chloride, plasticizer, polypropylene and polyethylene glycol terephthalate into a smelting furnace in sequence for mixing smelting, the temperature is controlled between 250 ℃ and 280 ℃, and the stirring and mixing are carried out for 45min through a stirring device;
adding the antistatic agent, the anti-blocking agent and the additive into the smelting furnace, mixing, continuously heating, controlling the temperature to be 190-230 ℃, and simultaneously stirring and mixing for 30min through a stirring device to fully dissolve and mix the antistatic agent, the anti-blocking agent and the additive with the raw materials to obtain a mixture;
in the fourth step, the mixed material mixed by the staff is led into an exhaust type double-screw extruder for plasticizing, the temperature of the exhaust type double-screw extruder is controlled to be 230-290 ℃, the exhaust type double-screw extruder, a metering pump and a filter are connected with a die head by a melt pipe, the melt extruded by the exhaust type double-screw extruder enters the melt pipe, then respectively passes through the filter and the metering pump, enters the die head and is led into a film blowing device for film blowing;
in the fifth step, the film body blown out by the film blowing is guided into a longitudinal drawing machine and a transverse drawing machine, and is stretched by a certain multiple in the longitudinal direction and the transverse direction under the action of external force, and is subjected to heat setting in a tensioned state;
and in the sixth step, after the stretched film body is cooled, the film body is rolled by using a rolling machine, and a rolled finished product is packaged and transferred to a warehouse for storage.
Preferably, the linear low density polyethylene and the metallocene polyethylene have the functions of effectively improving the strength, toughness and rigidity of the winding film, and simultaneously have good environmental stress cracking resistance, impact strength, tear strength and corrosion resistance, and can prolong the service life of the winding film.
Preferably, the polyethylene terephthalate can increase creep resistance, fatigue resistance and friction resistance of the winding film, the anti-adhesion agent is formed by mixing diatomite, talcum powder, calcium carbonate, synthetic silica and glass beads, different loose-shaped concave-convex shapes are formed on the surface of the winding film, a certain amount of air can be reserved between the surface layers of the film body, the effect of preventing the layers from being adhered to each other is achieved, and the additive is formed by mixing silica, calcium carbonate, barium sulfate and kaolin, and the anti-adhesion effect of the winding film can be enhanced.
