Abstract

The invention discloses a cold-resistant PVC oil-proof film with high tensile strength and a preparation process thereof. The invention particularly relates to the technical field of PVC film preparation. The film comprises a base film and an elastic film layer, wherein the elastic film layer coats the surface of the base film. The base film is prepared from the following raw materials in parts bymass: 50-80 parts of resin, 5-8 parts of a cold-resistant agent, 6-10 parts of a main plasticizer, 3-5 parts of a modifier, 0.8-1.5 parts of a filler and a proper amount of an auxiliary plasticizer.The PVC oil-proof film is prepared by the steps of mixing the raw materials, preparing a base film, preparing high-elasticity resin, rolling, drying and molding. The EVA resin and the PVC resin of which the average polymerization degree is greater than 2000 are used as main materials, the dosage ratio of the main plasticizer to the auxiliary plasticizer is controlled, and the elastic film layer coats the base film, so that the cold resistance and the tensile strength of the PVC oil-proof film are greatly improved.

Description

technical field [0001] The invention relates to the technical field of PVC film preparation, more specifically, the invention relates to a cold-resistant PVC oil-proof film with high tensile strength and a preparation process thereof. Background technique [0002] PVC plastic is one of the five general-purpose synthetic plastics, and it is the second largest plastic variety in the world after polyethylene. PVC plastic has good physical and mechanical properties, and can be used in the production of building materials, packaging materials, electronic materials, daily consumer goods, etc., and is widely used in various fields such as industry, agriculture, construction, transportation, power telecommunications, and packaging. Due to its poor cold resistance and low temperature impact resistance, the lower limit of the use temperature of hard PVC is generally -15°C, which limits the application of PVC materials in some aspects. Through the adjustment of PVC resin and additives...
