Abstract

The invention relates to a computer waterproof film and a preparing method thereof. The preparing method of the computer waterproof film includes the steps of konjac glucomannan sol preparation, blending, degassing, film manufacturing achieved through board inverting and film uncovering. According to the computer waterproof film, konjac glucomannan serves as a carrier, other auxiliaries are also used, and the computer waterproof film has good gel properties, heat isolation and light resistance, and is good in elasticity and high in flexibility and not prone to breaking. The computer waterproof film has the effects of good heat isolation, light resistance and elasticity and high in flexibility and has the advantage that a production material is environmentally friendly. Safety and usability completely accord with relative national standards. Konjac glucomannan serves as the main material, and the computer waterproof film further has the advantages of being low in production cost, little in environment pollution, free of harm to human bodies and the like, accords with the modern consumption concept and meets market requirements.

Description

technical field [0001] The invention relates to a waterproof membrane and a preparation method thereof, in particular to a computer waterproof membrane and a preparation method thereof, belonging to the technical field of daily necessities.
