Detailed Description
1-2, a novel barrier film for silicone rubber, including enhancement layer 1 and the laminating layer 2 of setting in enhancement layer 1 both sides, the overall thickness of laminating layer 2, enhancement layer 1 and laminating layer 2 is 0.08~0.012mm, the surface pressure of laminating layer 2 is equipped with antiseized line 3, antiseized line 3 is equilateral triangle, antiseized line 3's marginal recess degree of depth is 0.06~0.08mm.
Preferably, the overall thickness of the bonding layer 2, the reinforcing layer 1 and the bonding layer 2 is 0.1mm. The thickness of the isolating film is within the range of 0.08-0.012mm, and the tearing resistance and the stretching resistance can meet the use requirements, but the cost and the effect are considered, when the thickness of the isolating film is within the range of 0.1mm, the performance of the isolating film meets the use requirements, the cost is lower, and the production requirements are met.
The length of the side length of the equilateral triangle is 1.5-2.5 mm. Preferably, the side length of the equilateral triangle is 2mm. The anti-sticking patterns 3 are pressed on the outer surface of the bonding layer 2 through an embossing roller and pressed down along the sides of the equilateral triangle, and the depth of the patterns is between 0.06 and 0.08mm. When the isolating film is attached to the film, the adhesive force between the edge of the equilateral triangle and the film is smaller, and the middle part of the equilateral triangle is fully contacted with the film, so that the adhesive force is larger. The anti-sticking lines 3 reduce the tearing force applied to the isolation film during stripping, and ensure that the isolation film can be recycled.
The bonding layer 2: reinforcing layer 1: the thickness ratio of the bonding layer 2 is 2-3: 4-6: 2-3. Preferably, the bonding layer 2: reinforcing layer 1: the thickness ratio of the lamination layer 2 was 2.5:5:2.5. the middle reinforcing layer 1 is used as a reinforcing support of the isolating film, so that the tear resistance of the isolating film is enhanced, the temperature resistance is better, the isolating film is not easy to deform and crack during stripping, but the attaching between the isolating film and a film is not tight due to the excessively thick and hard reinforcing layer 1, and the film is easy to oxidize, so that the service performance of the isolating film is better. The bonding layers 2 on the two sides are light, thin and soft, and have good bonding performance with the film, and the surface embossing can be fully bonded, and has gap separation bonding force, so that the isolating film is easier to peel.
The laminating layer 2, the reinforcing layer 1 and the laminating layer 2 are integrally formed by blow molding, and the laminating layer 2, the reinforcing layer 1 and the laminating layer 2 are integrally compounded after the anti-sticking patterns 3 are pressed. The isolating film is formed by blow molding of three-layer co-extrusion equipment, and the three-layer structure is pressed together in the production process, and the three-layer structure is integrated without colloid adhesion after pressing due to higher production temperature. After the anti-sticking patterns 3 are pressed, the two sides of the three sides of the triangle are provided with arc-shaped indentations, so that the anti-sticking patterns are more attractive.
The anti-sticking lines 3 are equilateral triangles, the edge parts of the anti-sticking lines 3 are overlapped and distributed on the surface of the bonding layer 2, and the anti-sticking lines 3 are pressed down along the edges of the equilateral triangles.
