Abstract

The invention discloses a PVC (polyvinyl chloride) membrane and a processing method thereof. The PVC membrane is prepared from the following ingredients in parts by weight: 20-30 parts of polyvinyl chloride resin, 10-15 parts of polyvinyl alcohol, 10-12 parts of carbon black, 5-8 parts of plasticizer, 5-6 parts of fire retardant, 3-5 parts of flexibilizer and 2-3 parts of ceramic fiber. Through the carbon black and the fire retardant, the thermal stability of a product can be effectively improved, product performance is good, the PVC membrane can not be damaged even if the PVC membrane is usedfor a long time, and service life is long; in addition, the carbon black can be used for adsorbing ultraviolet rays, and a situation that the PVC membrane becomes yellow can be effectively avoided; the flexibilizer and the ceramic fiber are added to effectively improve the tensile strength of the product, and the service life of the product is further improved.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to a PVC film and a processing method thereof. Background technique [0002] With the development of the times, plastics have been widely used in industry and life. As a large class of general-purpose materials, polyvinyl chloride has been obtained for its small specific gravity, easy processing, corrosion resistance, non-toxicity and excellent comprehensive performance. widely used. However, most PVC films have problems such as poor physical stability and flammability. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a highly stable PVC film and a processing method thereof. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a PVC film, comprising the following components in parts by weight: 20-30 parts of polyvinyl chloride resin, 10-...
