Problems solved by technology

The sheet has poor weather resistance, so it turns yellow when exposed to UV light for a long time, and as a result, its transparency is reduced
[0015] In addition, conventional flame retardant sheets involve the problem of their low dimensional stability

Embodiment

[0432] Hereinafter, the present invention is described in more detail by means of examples, but the present invention is not limited to these examples.

[0433] 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 on which a silicone-based release treatment was performed was used Each cover film and substrate film were used for each of the following examples.

Synthetic example 1

[0434] (Synthesis example 1) (Preparation of slurry (b-1))

[0435] 100 parts by weight of cyclohexyl acrylate, 0.1 parts by weight of a photopolymerization initiator (trade name: "IRGACURE 651", manufactured by Ciba Specialty Chemicals Inc.), and 0.1 parts by weight of a photopolymerization initiator (trade name: "IRGACURE 184", 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 the outside of the flask by using a black light lamp to perform polymerization. At the point when moderate viscosity was obtained, the lights were turned off and nitrogen sparging was stopped. Thus, a slurry-like composition having a partially polymerized polymerization rate of 7% was prepared (hereinafter, this...

Abstract

Disclosed is a flame-retardant member that is flexible and highly flame retardant. Specifically disclosed is a flame-retardant polymer member which has a polymer layer (B) and a flame-retardant layer (A) on at least one surface of the polymer layer (B), wherein the flame-retardant layer (A) contains a stratified inorganic compound (f) in a polymer (X).

Description

technical field [0001] The present invention relates to flame retardant polymer components. The flame-retardant polymer member of the present invention is excellent in flexibility, and can make various adherends flame-retardant by flexibly adhering to them. In addition, the member can provide an article having flame retardancy by being adhered to any of various adherends. Background technique [0002] The flammability standards are classified into five grades in the order of decreasing burning difficulty, namely, non-combustibility, flame retardancy, flame retardancy, flame retardancy and flammability. In printed matters to be adhered to construction materials such as interior materials, exterior materials or decorative laminates for buildings or houses, or to interior materials or glass parts of transportation vehicles such as rail vehicles, ships or aircraft, according to its The applicable flame retardancy is determined for each application. [0003] A printed matter t...
