Embodiment 1～3、 comparative example 1～5

[0091] Cellulose ester-based resin compositions were prepared by compounding as shown in Table 1 and Table 2 below, and kneaded under the following processing test conditions to test processability and process coloring resistance. The torque at the time of kneading was measured for processability, and the process coloring resistance was evaluated as follows.

[0092] As the phosphoric acid ester represented by the above-mentioned general formula (1), the following phosphoric acid ester compound-1 was used. Phosphate ester compound-1 is a mixture of compounds with different n values.

[0093] Phosphate compound-1

[0094]

[0095] (In the formula, n represents a number from 1 to 5.)

[0096] In addition, the following phenol compound-1 was used as the phenol compound represented by the above general formula (2), the following triaryl phosphite compound-1 was used as the triaryl phosphite compound represented by the above general formula (3), and the following The diaryl p...

[0130] The cellulose ester resin composition was prepared by compounding as shown in the following Table 3, extruded under the following processing conditions to produce pellets, and the pellets were used for injection molding at 240° C. to obtain a cellulose ester resin composition of 1.6 mm×12.7 mm×127 mm The test piece for the flame retardancy test was subjected to a flame retardancy UL-94V test according to the following test method.

[0131]

[0132] Machine: TEX28V (product made in THE JAPAN STEEL WORKS, LTD.)

[0133] Processing temperature: 230~240℃

[0134]

[0135] A test piece with a length of 127 mm, a width of 12.7 mm, and a thickness of 1.6 mm was kept vertical, and the flame was removed after the lower end was in contact with the flame of the burner for 10 seconds, and the time until the ignition of the test piece disappeared was measured. Next, the flame disappeared for the second time for 10 seconds, and the time until the ignition disappeared was measure...

Abstract

Provided is a cellulose ester-based resin composition having excellent workability, processing coloration resistance, and flame retardance. Also provided is a molding having excellent color tone and flame retardance, the molding being obtained from the cellulose ester-based resin composition. The present invention is a cellulose ester-based resin composition characterized by containing 1 to 50 parts by mass of a phosphate ester represented by general formula (1) in relation to 100 parts by mass of a cellulose ester-based resin. (In formula (1), R1 and R2 each independently represent a hydrogen atom or methyl group, and n represents an integer 1 to 5.)

Description

technical field [0001] The present invention relates to a cellulose ester resin composition and its molded body. Background technique [0002] Polyester, polyester, etc. Synthetic resins such as amide and polycarbonate. Although these synthetic resins are excellent in formability, productivity, and mechanical properties, they are produced from petroleum, so when they are discarded in nature, they are difficult to degrade, so they place a heavy burden on the environment such as soil, and when they are incinerated , since carbon dioxide is produced, there is a problem from the viewpoint of preventing global warming. [0003] On the other hand, plant-derived resins are excellent in biodegradability and have little burden on the soil environment. In addition, plants are originally produced through photosynthetic reactions using carbon dioxide and water in the atmosphere as raw materials. Therefore, even if carbon dioxide is produced by burning, for example, the balance of car...
