Abstract
The utility model discloses a hydrophilic anti-adhesion membrane which comprises an anti-adhesion layer and a middle layer and is characterized by further comprising a hydrophilic layer. The middle layer is located between the anti-adhesion layer and the hydrophilic layer, and a layer of abherent is arranged on the anti-adhesion layer. The hydrophilic layer of the anti-adhesion membrane is good in an infiltration effect on water, and can be quickly infiltrated and unfolded to form a layer of a water membrane when the hydrophilic layer is contacted with the water. In the molding process of coiled materials, when high temperature self-adhesion materials are contacted with a silicon resin face of the anti-adhesion membrane, the water membrane on the reverse side of the anti-adhesion membrane can absorb large quantity of heat and then evaporates, temperature of a silicone oil face is rapidly lowered and does not exceed 100 DEG C all the time, namely, temperature of an anti-adhesion membrane face is greatly reduced, a 'silicon transfer' phenomenon of silicon resin is effectively avoided, and initial adhesiveness of self-adhesion coiled materials is not influenced.
