Problems solved by technology

[0011] So far, as a method of preventing fuzzing when the top seal tape is peeled off, the development of a device for detecting the unbonded portion of the tape is known (Patent Document 1); it is not a fundamental method for preventing the unbonded portion , but a countermeasure against the breakage of products using plastic base materials as the base material (Patent Documents 2, 3, 4); instead of improving the performance of preventing the occurrence of fluff caused by peeling of the paper carrier belt, the use of a size press A method of preventing fuzzing by applying a predetermined ratio of coniferous trees and broad-leaved trees and starch to both sides (Patent Document 5), but there is no known document that clearly focuses on improving paper chip type Publicly-known literature disclosing the fuzz prevention performance of the electronic component storage strip and its effective solution

Embodiment 1

[0051] Paperboard for chip-type electronic component storage paper is manufactured by three-layer papermaking consisting of a surface layer, a middle layer, and a bottom layer with different pulp compositions. At this time, mix and dissolve 30% NBKP, 70% LBKP, and prepare 400ml of CSF (Canadian Standard Freeness) pulp for the surface layer; use 20% NBKP, 20% LBKP, and 20% fine old paper , 40% newspaper used paper ratio, prepare 350ml CSF pulp for the middle layer; prepare 400ml CSF pulp with 25% NBKP, 25% LBKP, 50% newspaper old paper ratio , for the bottom layer. Aluminum sulfate was added to each pulp slurry to adjust the pH to 6.0, and 0.3% of polyacrylamide (trademark: Polysteron 1250, manufactured by Arakawa Chemical Industries) was added as an internal paper strength enhancer. The pulp slurry of the above-mentioned conditions is combined in a rotary screen 3-layer papermaking machine, so that the surface layer is 100g / m 2 , middle layer 200g / m 2 , bottom layer 50g / m ...

Embodiment 2

[0053] It carried out similarly to Example 1, and manufactured the chip-type electronic component storage strip. However, on the surface of the surface layer, a coating layer containing a fuzz-preventing resin consisting of an olefin-maleic acid copolymer resin having a glass transition temperature of 60° C. (Trademark: PM482, manufactured by Arakawa Chemical Industry Co., Ltd.).

[0054] The measurement results are shown in Table 1.

Embodiment 3

[0056] It carried out similarly to Example 1, and manufactured the chip-type electronic component storage strip. However, 100 parts by mass of polyacrylamide (trademark: PS117, manufactured by Arakawa Chemical Industries) and 2.0 parts by mass of styrene-maleic acid copolymer resin (trademark: PM382, manufactured by Arakawa Chemical Industries) were mixed to prepare the surface of the surface layer. Treatment agent for fuzz prevention.

[0057] The measurement results are shown in Table 1.

Abstract

The invention relates to a paper band with several chambers for containing chip electronic elements. The invention is characterized in that: the surface of said band that closing the top sealing band of said chamber has a coat with fluff-prevent resin and selective soluble resin; said fluff-prevent resin contains at least one of phenylethene-maleic acid polymer resin, alkene-maleic acid polymer resin, acrylic ester-acrylic acid polymer resin and phenylethealkenene-alkene-acrylic polymer resin. Said inventive band has high adhesive strength, without fluff when removing the top sealing band.

Description

technical field [0001] The present invention relates to a paper-made chip-type electronic component storage strip, specifically, the present invention relates to a chip-type electronic component storage strip, which has excellent bonding strength with the top seal tape and can prevent the The strip is fluffed. Background technique [0002] The chip-type electronic component storage strip is a carrier (a material for storing and holding) of chip-type electronic components, and is usually produced by processing a cardboard as follows. [0003] (1) The strip is cut into strips having a predetermined width from a cardboard. [0004] (2) Corner holes and round holes of a predetermined size are formed in the obtained cardboard strip. The corner holes are used to accommodate chip-type electronic components, and the round holes are used to make the strip advance only a specified distance in the component filling machine. [0005] (3) Adhere the bottom sealing tape on the back sid...
