Problems solved by technology

At first, it was peeled off manually. This method has many human factors and affects the judgment of strength.
Later, after sticking two pieces of glassine silicone oil paper together, they were pulled apart by a tensile machine to test the release force. However, the silicone oil paper is easily broken during the stretching process, which cannot truly reflect its release force. Therefore, there is no Corresponding release force detection method for glassine silicone oil paper

Embodiment 1

[0040] (1) Sample preparation

[0041] The test conditions are: ambient temperature 23±2°C, relative humidity 50±5%.

[0042]Paste the adhesive layer of NITTO 31B standard adhesive tape (the thickness of the PET silicon-coated film is 36 μm) on the silicone oil film layer of glassine silicone oil paper, and press lightly with your fingers to discharge the air bubbles on the bonding surface. Use a pressure roller to roll the laminated sample back and forth three times at a speed of about 300mm / min, and then cut out 4 test pieces with a width of 25mm and a length of 200mm.

[0043] The pressure roller is made of stainless steel, with a diameter (excluding the rubber layer) of 84mm, a width of 45mm, and a mass of 2000±50g. The hardness of the rubber layer covering the surface of the pressure roller (Shore A type) is 80°±5°, and the thickness of the rubber layer is 6mm.

[0044] (2) Heating and pressurization

[0045] Stack the 4 test pieces, and add a briquetting block with...

Embodiment 2

[0050] The surface of the pressing roller is not covered with rubber layer, and the types of standard adhesive tape and glassine silicone oil paper and other test conditions are the same as in Example 1.

[0051] The release forces of the four test pieces were measured to be 0.40N / 25mm, 0.45N / 25mm, 0.42N / 25mm, and 0.44N / 25mm respectively. Compared with Example 1, the differences in the detection results of the four parallel tests were significantly increased. Although the average value of the four parallel tests is still 0.43N / 25mm, it can be seen that covering the surface of the pressure roller with a rubber layer can make the bonding between the standard tape and the glassine silicone paper more uniform and complete, reducing the experimental pressure. error.

Embodiment 3

[0053] After the sample preparation in step (1) was completed, the heating and pressurizing operation in step (2) was not carried out, and other test conditions were the same as in Example 1.

[0054] The release forces of the four test pieces were measured to be 0.40N / 25mm, 0.42N / 25mm, 0.39N / 25mm, and 0.40N / 25mm respectively. The detection results of the four parallel tests have little difference, but the average value is also small, which is 0.40N / 25mm. It shows that heat and pressure can enhance the lamination strength between standard adhesive tape and glassine silicone oil paper, and make the test results more accurate.

[0055] Example 2

[0056] (1) Sample preparation

[0057] The test conditions are: ambient temperature 23±2°C, relative humidity 50±5%.

[0058] Paste the adhesive layer of NITTO 31B standard adhesive tape (the thickness of the PET silicon-coated film is 36 μm) on the silicone oil film layer of glassine silicone oil paper, and press lightly with your...

Abstract

The invention relates to a release force detection method for glassine silicone oil paper. The method includes the steps of: (1) pasting a detection adhesive tape on a silicone oil film layer of glassine silicone oil paper; and (2) performing peeling test on the glassine silicone oil paper and the detection adhesive tape pasted on the surface of the silicone oil film layer, thus obtaining the magnitude of release force between the silicone oil film layer and the detection adhesive tape. The method provided by the invention can improve the detection accuracy without increasing the operation complexity.

Description

technical field [0001] The invention relates to a testing method, in particular to a testing method for release force of glassine silicone oil paper. Background technique [0002] Glassine silicone oil paper, also known as translucent paper or cellophane, is a paper with good internal strength and transparency made of glassine base paper after coating. It has the characteristics of high temperature resistance, moisture resistance and oil resistance, and is generally used as packaging paper in the food and pharmaceutical industries. Developed countries have generally used glassine silicone oil paper in industries such as medicine, food packaging and automatic labeling, and the technology is relatively mature. However, in my country, low-priced plastic-coated paper was generally used in the past. At present, only a small number of enterprises have begun to imitate foreign technology for production. The product grade is not high, and there is no unified product standard. In r...
