Problems solved by technology

[0002] Plastic film is a common daily necessities for people nowadays. Plastic film has the advantages of good transparency, good moisture resistance, excellent heat resistance, convenient use, and low price. It is widely used in all walks of life. At present, plastic films on the market are mainly polymer Ethylene plastic film is the main product, but some products have problems such as wrinkles, poor transparency, uneven thickness, and many fish eyes in the film. The higher the higher, therefore, the higher the requirements for its tear strength

Abstract

The invention discloses a tear-resistant hard plastic film, which comprises the following raw materials in parts by weight: 1-3 parts of vinyl carboxylate, 0.1-0.2 part of azodicarbonamide, 0.1-0.3 part of divinyl benzene, 0.5-1 part of zinc pyrithione, 120-140 parts of polytetrafluoroethylene, 3-5 parts of aluminum dihydrogen phosphate, 6-8 parts of isopropanol, 1-2 parts of ammonium ferrous sulfate, 2-4 parts of trichloroisocyanuric acid, 15-20 parts of silicon micropowder, 1-2 parts of magnesium stearate, 0.6-1 parts of Tetrakis hydroxymethyl phosphonium sulfate and 15-20 parts of a fiber dispersion. Esterified crosslinked fiber obtained can effectively improve the compatibility in the polytetrafluoroethylene, and the tear strength of the finished product can be further improved.

Description

technical field [0001] The invention belongs to the field of plastic films, and in particular relates to a tear-resistant rigid plastic film and a preparation method thereof. Background technique [0002] Plastic film is a common daily necessities for people nowadays. Plastic film has the advantages of good transparency, good moisture resistance, excellent heat resistance, convenient use, and low price. It is widely used in all walks of life. At present, plastic films on the market are mainly polymer Ethylene plastic film is the main product, but some products have problems such as wrinkles, poor transparency, uneven thickness, and many fish eyes in the film. The higher the higher, therefore, the higher the requirements for its tear strength. Contents of the invention [0003] The object of the present invention is to provide a tear-resistant rigid plastic film and a preparation method thereof for the defects and deficiencies of the prior art. [0004] To achieve the abo...
