Problems solved by technology

[0003] In the existing adhesive film, there is a problem of poor elasticity. In the long-term use process, the adhesive film will be easily broken due to excessive external force or impact strength. It is easy to cause uneven mixing of various raw materials, which will affect the stretchability, transparency, adhesion and thermal shrinkage of the adhesive film, greatly reducing the use effect

Abstract

The invention discloses a high-elasticity adhesive membrane and a production method thereof. The method comprises the following steps: (1) firstly, adding a base material, filler, butyl rubber powderand the butyl titanate into a stirring device for performing an initial uniform stirring operation, wherein the initial stirring time is controlled to be 40-60 minutes, and the initial stirring temperature is controlled to be 70-80 DEG C; then, adding calcium stearate and sodium rosinate and dispersing into the obtained mixture, and performing a secondary uniform stirring operation to obtain a mixture A, wherein the secondary stirring time is controlled to be 70-90 minutes, the secondary stirring temperature is controlled to be 90-110 DEG C, and the stirring rates of the two times are both controlled to be 200-240 rpm; (2) enabling the mixture A obtained in the step (1) to stand, filtering, and then mixing the product with dicyclohexyl phthalate, and pressurizing to 0.6-1.2Mpa, and stirring evenly to obtain a mixture B. The production method greatly improves the product quality by carrying out a plurality of times of stirring operations on the raw materials in batches and by means of circular and rotational motion of mixing blades and helical blades.

Description

technical field [0001] The invention relates to the technical field of adhesive films, in particular to a highly elastic adhesive film and a production method thereof. Background technique [0002] The main raw materials of adhesive film are polypropylene film, acrylic glue, hot melt adhesive and oil glue, etc., which are often used in packaging and bonding, and have a wide range of applications. From the perspective of the industrial chain, the upstream industries in the adhesive film manufacturing industry are mainly petrochemical enterprises that produce various synthetic resins such as polyvinyl chloride, polyethylene and polypropylene, while the downstream industries mainly include food processing, daily necessities, medical supplies, electrical appliances, etc. , oil, gas, construction and automobiles and many other fields.
