A kind of manufacturing method of variable material adhesive tape die-cut product

Abstract

The invention discloses a manufacture method of mutability material adhesive tape die cutting products. The method includes the steps: 1) primary back rolling: fitting a roll-shaped abrasive tape withroll-shaped release paper to form a first fitting coiled material, and enabling a take-up direction of the first fitting coiled material to be opposite to a pay-off direction of the roll-shaped abrasive tape; 2) primary standing: standing the first fitting coiled material for 12 hours or more; 3) secondary back rolling: peeling the release paper in the first fitting coiled material to perform pay-off, fitting the release paper with second release paper to perform pay-off to form a second fitting coiled material, and setting a pay-off direction of the second fitting coiled material opposite tothe take-up direction of the first fitting coiled material; 4) secondary standing: standing the second fitting coiled material for 12 hour or more; 5) fitting, die cutting and forming: peeling the release paper in the second fitting coiled material to perform pay-off, fitting the release paper with third release paper, and performing cutting to form the products. According to the method, telescopic deformation of the adhesive tape can be effectively controlled, and the die cutting accuracy of the products is improved, so that the yield of the products is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of die-cutting, and in particular relates to a method for making a die-cutting product of variable material adhesive tape. 【Background technique】 [0002] With the development of science and technology, the precision and speed of the knife mold have been greatly exerted, so the knife mold is widely used in electronic materials, printing and packaging, plastic packaging, leather, rubber products and other industries. Die-cut tape products generally include an adhesive layer and a release paper layer. During the production process, the adhesive layer and the release paper layer need to be bonded together and cut into the designed shape, but the adhesive layer and the release paper layer have different viscosities. , the strength of stretching when the two are bonded is different, resulting in the size of the processed product growing or shrinking irregularly with time, and the tolerance fluctuation value is ...

Problems solved by technology

Die-cut tape products generally include an adhesive layer and a release paper layer. During the production process, the adhesive layer and the release paper layer need to be bonded together and cut into the designed shape, but the adhesive layer and the release paper layer have different viscosities. , the strength of stretching when the two are bonded is different, resulting in the size of the processed product growing or shrinking irregularly with time, and the tolerance fluctuation value is about 0.8mm; while the customer requires a tolerance of only ±0.1mm, which has been Far outside the tolerance range, resulting in a severely defective product
