Problems solved by technology

[0010] Among them, due to the high antistatic effect of the surfactant, it has the effect of making the polyolefin resin foam sheet exhibit an antistatic effect in the early stage after manufacture, but on the other hand, there is a large amount of antistatic effect in the polyolefin resin foam sheet. The possibility of oozing out from the surface of the material and adhering to the glass substrate

Embodiment 1

[0095] 100 parts by mass of low density polyethylene resin (trade name: "LF580", density: 929kg / m 3 , MFR=4.0g / 10min) was blended with 7 parts by mass of a polymer antistatic agent manufactured by Sanyo Kasei Co., Ltd. (polyether polypropylene block copolymer, trade name: "PELESTAT 300", crystallization temperature: 85.4°C , MFR=30g / 10 minutes), 1 mass part of anionic surfactant manufactured by Sanyo Chemical Industry Co., Ltd. (containing more than 90 mass% of alkyl sulfonates with 12 to 16 carbon atoms, trade name "CHEMISTAT 3033", Softening point 70°C, hydrophilic-lipophilic balance value 40) and 0.05 parts by mass of a cell regulator masterbatch (azodicarbonamide-containing masterbatch: trade name "CELLMIC MB1023") manufactured by Sankyo Kasei Co., Ltd. The compounded material was supplied to the 1st extruder (barrel diameter: (phi)90mm) of a tandem extruder, and it melt-kneaded so that the maximum attained temperature in this extruder might become 210 degreeC.

Embodiment 2~5

[0108] The foam seat|seet was produced similarly to Example 1 except having changed the kind and quantity of the anionic surfactant contained in foam seat|seet, and it evaluated similarly to Example 1.

[0109] It should be noted that in Example 2, straight-chain alkylbenzenesulfonate (softening point 270°C, hydrophilic-lipophilic balance value 36.2) manufactured by Kao Corporation was used. The trade name "NEOPELEX No.6" of the main component (containing about 60% by mass of linear alkylbenzene sulfonate, the remainder: sodium sulfate), in Examples 3, 4, and 5, the "NEOPELEX No.6 " was used in combination with "CHEMISTAT 3033" used in Example 1.

Embodiment 6

[0111] In addition to changing the polymer antistatic agent to potassium ionomer manufactured by DU PONT-MITSUI POLYCHEMICALS CO.,LTD. (trade name "ENTIRA AS SD100"), and changing the type and amount of anionic surfactant , The foam seat|seet was produced similarly to Example 1, and it evaluated similarly to Example 1.

[0112] It should be noted that, in Example 6, dialkyl succinate sulfonates such as dioctyl sodium sulfosuccinate manufactured by Daiichi Kogyo Pharmaceutical Co., Ltd. (softening point 160° C., hydrophilic-lipophilic balance value 41.9) The trade name "NEOCOL YSK" which is the main ingredient (approximately 70% by mass active ingredient).

Abstract

The present invention provides a polyolefin resin foaming sheet suitable for being used as a spacing paper of a glass substrate used for a panel display. The polyolefin resin foaming sheet contains polyolefin resin, high-polymer antistatic agent and surface active agent. The surface active agent contains negative ion surface active agent based on a Davis method, having a hydrophilic-lipophilic balance value which is more than 20. With respect to 100 parts by mass of the polyolefin resin, the content of the high-polymer antistatic agent is 3-20 parts by mass, and the content of the negative ion surface active agent is 0.1-5 parts by mass.

Description

technical field [0001] The present invention relates to a polyolefin resin foam sheet, more specifically, to a polyolefin resin foam sheet containing a polymer antistatic agent and a surfactant. Background technique [0002] The foamed polyolefin-based resin sheet is used as a packaging material for electronic components and home appliances, as an inserting paper for glass, and the like because it is flexible and has excellent cushioning properties. [0003] For example, glass substrates for flat panel displays such as liquid crystal displays and plasma displays are supplied from glass manufacturers to display manufacturers by laminating with polyolefin-based resin foam sheets interposed therebetween. [0004] When such a glass substrate has foreign matter attached to its surface, it may cause disadvantages such as failure of the flat-panel display, so it is washed with water before use. [0005] From such a situation, the foamed polyolefin-based resin sheet used as a space...
