Antistatic flame-resistant environmentally stable peelable protective film and preparation method thereof

Abstract

The invention discloses an antistatic flame-resistant environmentally stable peelable protective film and a preparation method thereof. The antistatic flame-resistant environmentally stable peelable protective film is prepared from 10 parts of a vinyl chloride / vinyl acetate resin, 1 to 4 parts of polyurethane resin, 0.05 to 0.2 parts of a conductive filling material, 0.025 to 0.1 parts of a compatibility modifier and 0.025 to 0.1 parts of plasticizers. The antistatic flame-resistant environmentally stable peelable protective film adopts a vinyl chloride / vinyl acetate resin and a polyurethane resin as film forming materials, has a volume resistivity smaller than 10<8>omega.cm, satisfies antistatic requirements, and has flame-resistant performances reaching to V0 level, acid and alkali erosion-resistant performances and a good environmental stability. The antistatic flame-resistant environmentally stable peelable protective film can be coated on the surfaces of regular and irregular metal objects, ceramic objects, cement brick tiles and polymers in multiple ways of spray coating, roller coating and brush coating. An adhesion stress acting on a base plate can be regulated and controlled through changes of types and proportions of vinyl chloride / vinyl acetate resin components and polyurethane resin components, thus the antistatic flame-resistant environmentally stable peelable protective film can be utilized for decoration and protection of different equipment and devices.

Description

technical field [0001] The invention relates to an antistatic, flame-retardant and environmentally stable peelable protective film and a preparation method thereof. Background technique [0002] Solid protective films (such as pressure-sensitive tapes, etc.) are suitable for large-area components and equipment. However, for many parts or products with irregular shapes, people often expect a convenient application method (such as dipping or spraying) so that they can be protected quickly and efficiently. In addition, the liquid protective film can also be used to quickly remove toxic and harmful pollutants (including nuclear waste dust particles, etc.), reduce the sensitivity of equipment or devices to environmental humidity, and improve the corrosion resistance of equipment. Therefore, peelable liquid protective films are important for many fields. [0003] The development of high-performance liquid protective film technology has attracted widespread attention, and differe...

However, this is detrimental to the long-term environmental stability of the protective film

Since these release agents are generally inert (do not have good compatibility with the polymer body), they will migrate or even lose in the protective film over time, which will inevitably affect the service life and reliability of the film to a certain extent. Peeling properties, their loss may even lead to cracking or weathering of the protective film, thereby reducing the protective effect of the film
