Formula, preparation process, use method and application of high-elasticity membrane

Abstract

The invention discloses a formula, a preparation process, a use method and application of a high-elasticity membrane. The formula comprises the following components in parts by weight: 80-120 parts ofpolyvinyl chloride (PVC) and 2-8 parts of liquid rubber, wherein the polymerization of the polyvinyl chloride (PVC) is 1300-2100. Compared with the prior art, the membrane of the formula is very goodin elasticity and elongation at break at a relatively low temperature when the amount of calcium powder and the content of the liquid rubber are accurately controlled, and in addition, due to the adoption of an environmental-friendly plasticizer and a stabilizer, the product is also good in environment protection. The high-elasticity membrane disclosed by the invention has the advantages of highuse security. Fuel gas equipment is dangerous to use in a residential community, and life-threatening explosion can be resulted, and the risk can be avoided if a cold draw membrane is mounted.

Description

technical field [0001] The invention discloses a formula, a manufacturing process, a using method and an application of a high elastic film. Background technique [0002] PVC is the second largest plastic in the world, and PVC calendered film, as one of its products, has the advantages of good flexibility, easy molding and processing, and bright colors, and is widely used in industrial and daily necessities. In order to reduce the cost of the traditional PVC calendering film, a certain amount of calcium powder is added, and the addition of calcium powder will reduce the elasticity and elongation at break of the PVC film. This defect restricts the application of traditional PVC film in some special fields. [0003] The existing ordinary PVC film tensile data is shown in the following table. [0004] [0005] The existing PVC elastic film is widely used in ceilings because of its light weight, convenient spray painting and beautiful effect. Usually, in order to obtain a ...

AI Technical Summary

Problems solved by technology

The existing application of this kind of film must be heated, and the temperature is controlled after reaching a certain temperature. The room needs to be preheated to 60-70°C. The use has high requirements on the external environment and process, and it is not easy to be widely used and promoted at present.

[0006] In addition, stretching the existing PVC film, as long as the heating temperature is higher than 70 degrees, harmful substances will be released, which will cause harm to construction workers and people living in the environment.
