Embodiment 1

[0018]

[0019] Its preparation method is:

[0020] Add the material components in the above proportions into the PVC resin, and then stir and mix uniformly with a high-speed mixer to form a mixture A, then plasticize and knead the mixture A through an internal mixer, and then carry out the mixture A through an open mixer. Heat smelting, molding, and then the rollers of the calender press and stretch the molded material into a film of a certain thickness, and finally peel off the formed film, cool and shape it, thereby forming a PVC film. The thickness of the film in this embodiment is 0.3mm.

Embodiment 2

[0022]

[0023] The preparation method is the same as in Example 1, and the thickness of the prepared film is 0.4mm.

Embodiment 3

[0025]

[0026] The preparation method is the same as in Example 1, and the thickness of the prepared film is 0.5mm.

Abstract

The invention discloses durable cable PVC film. The durable cable PVC film is prepared from, by weight, 40%-70% of PVC resin, 10%-50% of plasticizer, 1%-10% of stabilizer, 1%-30% of filling agent, and 1%-10% of colorant. According to the durable cable PVC film, because of the mutual coordination of PVC resin, the plasticizer, the stabilizer and the filling agent, the prepared thin film is smooth in surface, uniform in thickness, free of obvious spots and free of oil stains, impurities and creases, the stretch rate of the thin film is 250%-300%, the water absorption rate is smaller than or equal to 0.5%, the natural shrinking percentage is smaller than or equal to 0.5%, smog during combustion is small, and the combustion cannot last.

Description

technical field [0001] The invention relates to the field of PVC film preparation, in particular to a durable cable PVC film. Background technique [0002] The main component of PVC is polyvinyl chloride, which is light yellow, translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. And lower than polypropylene, there will be whitening at the inflection. Common products include plates, pipes, shoe soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. [0003] The price and cost of PVC film are low and the application range is wide, so it is getting more and more attention and utilization in the market. Especia...
