Problems solved by technology

However, such a method cannot impart sufficient flame retardancy to the molded article, and dripping of burning materials occurs during combustion, and sometimes it is impossible to obtain a molded article that meets the V-0 or VTM-0 standard in the UL94 vertical burning test.

Embodiment 1

[0122] "Nature Works 4032D" manufactured by Kaichiru Dou Co., Ltd. was used as the lactic acid resin (A), and "Epoxysilane coupling agent treatment BF013ST" manufactured by Nippon Light Metal Co., Ltd. was used as the metal hydroxide (B). One is a kenaf fiber manufactured by a company as a natural fiber (C). Dry-blended 50 parts by mass of epoxy silane coupling agent-treated BF013ST and 3 parts by mass of kenaf fibers to 100 parts by mass of lactic acid resin (A), and supplied it to a 25 mmφ co-direction twin-screw extruder "Technobell Corporation "Manufacturing", melting and kneading at 200°C. The kneaded composition was extruded through a die, and then quenched with a casting roll at about 43° C. to produce a sheet with a thickness of 400 μm. The flame retardancy (UL94V) of the obtained sheet was evaluated. The results are shown in Table 1.

Embodiment 2

[0124] With respect to Example 1, except having changed the addition amount of the epoxy silane coupling agent process BF013ST into 75 mass parts, it carried out similarly to Example 1, and produced the sheet|seat.

[0125] That is, after dry-blending 75 parts by mass of epoxy silane coupling agent-treated BF013ST and 3 parts by mass of kenaf fibers to 100 parts by mass of lactic acid resin (A), the same method as in Example 1 was used to prepare the thickness 400 μm slices. The flame retardancy (UL94V) of the obtained sheet was evaluated. The results are shown in Table 1.

Embodiment 3

[0127] With respect to Example 1, except having changed the addition amount of the epoxysilane coupling agent process BF013ST into 100 mass parts, it carried out similarly to Example 1, and produced the sheet|seat.

[0128] That is, after dry-blending 100 parts by mass of epoxy silane coupling agent-treated BF013ST and 3 parts by mass of kenaf fibers to 100 parts by mass of lactic acid resin (A), thickness 400 μm slices. The flame retardancy (UL94V) of the obtained sheet was evaluated. The results are shown in Table 1.

Abstract

A resin composition comprising 100 parts by mass of lactic acid resin (A), 50 to 100 parts by mass of metal hydroxide (B) and 0.1 to 30 parts by mass of fiber (C), wherein the fiber (C) is a natural fiber or / and a fiber derived from natural material. Moldings thereof satisfy the V-0 standard or VTM-0 standard according to UL94 vertical combustion test (UL94V, UL94VTM).

Description

technical field [0001] The present invention relates to a resin composition derived from a plant material and a molded article thereof, and in particular, to a resin composition derived from a plant material having high flame retardancy and a molded article thereof. Background technique [0002] Plastic has penetrated into all fields of life and industry, and the annual production volume of the world has reached about 100 million tons. Most of them are discarded after use, and it has been recognized that this is one of the causes of damage to the global environment. Therefore, in recent years, the effective use of depleted resources has been emphasized, and the use of renewable resources has become an important issue. [0003] At present, as its solution strategy, the most attention is the utilization of plant-based plastics. Plant-based plastics can not only save exhausted resources but also have excellent recyclability when using non-exhausted resources to manufacture pl...
