As a result, it becomes difficult to apply the sheet to uses requiring a satisfactory appearance
[0010] In addition, conventional flame-retardant sheets do not have moisture-conditioning properties or are insufficient in moisture-conditioning properties in some cases
In those cases, for example, there arises a problem that condensation occurs when the sheet is used for an interior wall surface of a house or the like
[0011] In addition, conventional flame-retardant sheets do not have moisture-preventing property or are insufficient in moisture-preventing property in some cases

Embodiment

[0509] Hereinafter, the present invention is described in more detail by means of examples, but the present invention is not limited to these examples.

[0510] It should be noted that a biaxially stretched polyethylene terephthalate film (trade name: "MRN38", manufactured by Mitsubishi Chemical Polyester Film) having a thickness of 38 μm which had been subjected to a silicone-based mold release treatment on one surface was used for Each cover film and base film of each of the following examples were used.

[0511]

[0512] The following flame retardancy of the polymer sheet was evaluated.

[0513] pass figure 2 The evaluation of flame retardancy was carried out in the horizontal combustion test shown in . figure 2 The measurement method is shown. Each polymer sheet was cut out into a 5 cm x 12 cm piece, which was then evaluated. Care should be taken to peel off the cover films on both sides of each polymer sheet.

Synthetic example 1

[0581] (Synthesis Example 1) (Preparation of Slurry (b-1))

[0582] 50 parts by weight of isobornyl acrylate, 50 parts by weight of lauryl acrylate, 0.1 part by weight of a photopolymerization initiator (trade name: "IRGACURE651", manufactured by Ciba Specialty Chemicals Inc.) and 0.1 part by weight of a photopolymerization initiator (trade name: "IRGACURE184", manufactured by Ciba Specialty Chemicals Inc.) was stirred in a four-necked separable flask equipped with a stirrer, a thermometer, a nitrogen gas introduction tube, and a cooling tube until the mixture became homogeneous. Thereafter, nitrogen bubbling was performed for 1 hour to remove dissolved oxygen. Thereafter, UV light was applied from outside the flask by using a black light lamp to perform polymerization. At the point when a moderate viscosity was obtained, the lights were turned off and nitrogen sparging was stopped. Thus, a partially polymerized slurry composition having a polymerization ratio of 7% was prep...

Synthetic example 2

[0583] (Synthesis Example 2) (Preparation of Slurry (a-1) Containing Layered Inorganic Compound)

[0584] 30 parts by weight of layered clay mineral (trade name: "Lucentite SPN", manufactured by Co-op Chemical Co., Ltd., shape: flat plate) was added to 100 parts by weight of cyclohexyl acrylate, 0.2 parts by weight of 1,6 - Hexylene glycol diacrylate, 0.2 parts by weight of a photopolymerization initiator (trade name: "IRGACURE651", manufactured by Ciba Specialty Chemicals Inc.), and 0.2 parts by weight of a photopolymerization initiator (trade name: "IRGACURE184", manufactured by Ciba Specialty Chemicals Inc. . system) formed monomer mixture, and then the whole was allowed to stand at room temperature (25° C.) for 24 hours. Thus, a monomer mixture (cloudy) to which layered clay minerals have been added is obtained. Thereafter, the monomer mixture to which the layered clay mineral was added was irradiated with ultrasonic waves from an ultrasonic disperser (manufactured by NIP...
