Abstract

The invention relates to a water bag film and a preparation method thereof. The problems that in the prior art, a water bag film is insufficient in strength and poor in fastness and functionality aresolved. The water bag film comprises the following components in parts by weight: 70-80 parts of polyvinyl chloride resin, 35-38 parts of dioctyl terephthalate, 2-2.6 parts of epoxy soybean oil, 2-4 parts of a barium-zinc liquid stabilizer and 4.5-5 parts of a cold-resistant agent. The water bag film is good in strength, and fastness and functionality of the water bag film are better than those ofan existing water bag film on the market.

Description

technical field [0001] The invention relates to a water bag film and a preparation method thereof, which are mainly used for processing and preparing hot water bags. Background technique [0002] The hot water bag is usually square, with a hot water inlet and outlet at one end, sealed with a plug, mostly a spiral plug, and its use is to pour hot water into it to keep warm. Now this traditional hot water bag is gradually being used as a storage type. Replaced by the electric hot water bag, the water storage type electric hot water bag is filled with liquid, has a heater inside, and plugs in the power to heat the liquid in the bag, so as to achieve the purpose of heating. The water bag film that is used to make hot water bag also has the problems of insufficient strength, fastness and poor functionality in the market now. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a wa...
