Problems solved by technology

[0002] Usually the release film refers to the coating of silicone oil on the surface of the polyester film to play the role of anti-sticking; the surface of the release film can have a smooth surface and a matte surface, but the pressure-sensitive adhesive tape made of this traditional release film When using label tape, the beautification effect of the glue surface is not ideal. When ordinary release film and pressure-sensitive adhesive tape are bonded, air bubbles are likely to form between the two
Using embossed release paper, although it can achieve the effect of air bubble removal, but because the release paper is easy to absorb water, the tear resistance is not high, it is difficult to observe the rubber surface, and there are paper scraps on the edge after die-cutting, so it cannot be used by high-end product used

Embodiment 1~5

[0020] Embodiment 1~5: a kind of manufacturing method for embossed release paper, comprises the following steps:

[0021] Step 1: The preparation process of the film coating layer is as follows:

[0022] Step 1, 100 parts of high-density polyethylene, 120-180 parts of low-density polyethylene, 10-30 parts of styrene-isoprene-styrene block copolymer, block copolymerization of styrene and butadiene Put 5~15 parts of compound, 0.5~1.5 parts of paraffin, 0.1~0.5 parts of glycerin, 5~10 parts of POE polyolefin elastomer, 0.3~0.8 parts of silane coupling agent into the mixer and mix and stir for 20~30min to form a mixture ;

[0023] Step 2. The mixture obtained in step 1 is heated and bridged by the twin-screw at the feed port of the laminating machine to obtain the melted mixture. The temperature of the heating bridge is 150-200°C;

[0024] Step 3. The molten mixture obtained in step 2 is further heated to 220~250°C at the feeding screw to obtain a fluid mixture, and pressurized ...

Abstract

The invention discloses a manufacturing method of embossed release paper. The manufacturing method of the embossed release paper comprises the following steps: adding 100 parts of high-density polyethylene, 120-180 parts of low-density polyethylene, 10-30 parts of styrene-isoprene-styrene block copolymers, 5-15 parts of styrene-butadiene block copolymers, 0.5-1.5 parts of paraffin, 0.1-0.5 part of glycerinum, 5-10 parts of POE polyolefin elastomers and 0.3-0.8 part of coupling agents into a stirrer for stirring; heating and bridging the mixture via two screws at a feeding opening of a laminating machine to obtain the molten mixture; further heating the molten mixture to 220-250 DEG C again at a feeding screw to obtain a fluid mixture; heating the fluid mixture to 260-280 DEG C again at a screw outlet, changing the fluid mixture into a cloth-shaped mixture, and extruding the cloth-shaped mixture. The embossed release paper manufactured by the method is clear in embossed mesh lines, uniform in depth and uniform in distribution lines; no bubbles are generated between the formed embossed lamination release paper and a pressure-sensitive adhesive when the embossed polyethylene-coated release paper is fit with the pressure-sensitive adhesive.

Description

technical field [0001] The invention relates to a manufacturing method for embossed release paper, which belongs to the technical field of release materials. Background technique [0002] Usually the release film refers to the coating of silicone oil on the surface of the polyester film to play the role of anti-sticking; the surface of the release film can have a smooth surface and a matte surface, but the pressure-sensitive adhesive tape made of this traditional release film When using label tape, the beautification effect of the glue surface is not ideal. When the ordinary release film is attached to the pressure-sensitive adhesive tape, air bubbles are likely to form between the two. Using embossed release paper, although it can achieve the effect of air bubbles, but because the release paper is easy to absorb water, the tear resistance is not high, it is difficult to observe the glue surface, and there are paper scraps on the edge after die-cutting, so it cannot be used ...
