Embodiment 1）

[0082] Polybutylene succinate-based resin "GS Pla" manufactured by Mitsubishi Chemical Corporation was frozen with liquid nitrogen, and pulverized to a particle size passing through a 75 μm sieve using a Linrex Mill manufactured by Hosokawa Micron Corporation. Hereinafter, the powder obtained in this way is called "resin powder".

[0083] The volume average particle diameter (D50) of this resin powder was measured. Specifically, a small amount of resin powder was added to a beaker together with purified water and a surfactant, and a sample obtained by stirring it with ultrasonic waves was prepared. 2100" analysis. As a result, the volume average particle diameter (D50) of the resin powder was 48 μm.

[0084] In addition, the softening point of the resin powder was measured. Specifically, 1 g of resin powder was used as a sample, and the analysis was performed using a flow tester "CFT-500D" manufactured by Shimadzu Corporation. Here, the temperature increase rate was set to...

Embodiment 2）

[0104] Disperse 100 parts by mass of resin powder and 1.5 parts by mass of silica "RY50" manufactured by Aerosil Corporation of Japan as hydrophobic silica in a volume ratio of 70:30 containing water and isopropanol and also containing a very small amount in the surfactant dispersion medium. Next, a frame is provided on the peelable sheet, and the above-mentioned dispersion liquid is poured into the frame. In addition, the supply amount of the dispersion liquid was adjusted so that the amounts of the resin powder and hydrophobic silica per unit area were the same as in Example 1. Next, it was dried by heating it for 30 minutes in an oven set at a temperature of 60°C. Thus, the layer L made of the previous powder is formed on the peelable sheet.

[0105] A plurality of layers L were formed in this way, and these layers L were then heated under different temperature conditions in the same manner as in Example 1. Then, the molten state, porosity, and strength of the heated lay...

Embodiment 3）

[0107] Except that the amount of hydrophobic silica is set to 1.0 parts by mass relative to 100 parts by mass of the resin powder, preparation of the dispersion, supply to the frame and drying are carried out in the same manner as in Example 2, thereby forming a plurality of The layer L formed by these powders. Next, these layers L were heated under different temperature conditions in the same manner as in Example 1. Then, the molten state, porosity, and strength of the heated layer L were evaluated in the same manner as in Example 1. These results are summarized in Table 1 below.

Abstract

A method for manufacturing a porous flexible sheet according to the present disclosure includes forming a layer that includes a mixture including thermoplastic resin particles and inorganic particles and thermally fusing the thermoplastic particles to each other and to the inorganic particles while keeping at least a part of clearances between the particles.

Description

[0001] This application claims priority based on Japanese Patent Application Japanese Patent Application No. 2013-085634 for which it applied on April 16, 2013, and takes in all the content of this basic application into this application. technical field [0002] The present invention relates to a porous flexible sheet, its manufacturing method, and its manufacturing device. Background technique [0003] Flexible sheets have a variety of uses. Labels are one of the uses of flexible sheets. [0004] For labels formed of flexible sheets, for example, in JP-A-2007-283745, JP-A-2010-184470, and JP-A-2011-107418, it is proposed to manufacture by the following method : First, an electrostatic latent image is formed on a photosensitive drum, and then toner is supplied thereto, thereby forming a toner layer having a shape corresponding to the electrostatic latent image, and then the toner layer is transferred from the photosensitive drum to a release sheet on the material, and the...
