Abstract

The invention discloses a high-adsorptivity automatic exhausting type protective film which is prepared from the following raw materials: 20%-30% of hexylene glycol dimethacrylate, 10%-25% of tripropylene glycol butyl diacrylate, 15%-25% of hydroxyethyl methylacrylate, 20%-30% of methacrylamide, 5%-12% of 2-ethylhexyl acrylate, 15%-25% of diluent, 2%-4% of additive and 3%-5% of coalescing agent. The high-adsorptivity automatic exhausting type protective film provided by the invention is prepared from macromolecule components and the additive is adopted for inhibiting reaction rate, so that gelling is avoided, and meanwhile, crosslinking density is increased, cohesion is enhanced, structure stability is guaranteed, base structure and production process of the protective film can be effectively improved and safety and stability in production and use can be promoted.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a highly absorbing self-venting protective film. Background technique [0002] With the development of social science and technology and the improvement of living standards, people's requirements for daily necessities are also increasing. In order to protect commonly used items, the application of protective film is very wide. Dust and waterproof effect. [0003] However, the current protective film has complex components and backward production technology, which greatly reduces the stability of the protective film, and has poor air permeability and poor stability during protection, which is not conducive to people's daily use and industrial production. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a highly absorbing self-venting protective film. [0005] In order to achieve the abov...
