Embodiment 1）

[0110]

[0111] Kraft lignin is used as a lignin derivative.

Embodiment 1

[0112] The kraft lignin in Example 1 is contained in the cooking liquor (black liquor) discharged when pulp is produced by kraft pulping, wherein an aqueous sodium hydroxide solution and an aqueous sodium sulfide solution are brought into the cooking liquor. In Example 1, lignin base (370959), a reagent manufactured by Sigma-Aldrich Co. LLC., was used as the sulfate lignin.

[0113]

[0114] Kraft lignin (10 g, lignin base, manufactured by Sigma-Aldrich Co., Ltd.) was dissolved to 80% by mass Alkanes (300mL) and acetic acid (30mL) mixed solution. Under stirring, 50% by mass of dimethylamine solution (22.5 mL, 0.25 mol) and 37% by mass of formamide solution (18.7 mL, 0.25 mol) were added thereto, followed by allowing to react in a 60°C water bath 4 hours. Thereafter, the resulting reaction solution was added dropwise to acetone to form a precipitate. The precipitate was filtered with suction and the residue was washed with water and then dried in a desiccator, whereby the ...

Embodiment 2）

[0137] Using the kraft lignin described in Example 1 as starting material the following reaction products were obtained.

[0138]

[0139] Kraft lignin (10 g) was dissolved in pyridine (250 mL). Phosphorus oxychloride (10 mL, 0.11 mol) was added thereto under stirring. After 1 hour, a mixed solution of 50% by mass dimethylamine solution (60 mL, 0.67 mol) and pyridine (60 mL) was additionally added. After 1 hour, the resulting reaction solution was added dropwise to water to terminate the reaction, followed by centrifugation (11,000 rpm, 15 min). The obtained precipitate was repeatedly washed with acetone and air-dried in a fume hood, thereby obtaining a reaction product. The phosphorus content in the resulting reaction product was measured by the flask combustion method (titration method). The nitrogen content in the reaction product was measured by elemental analysis. The results are shown in Tables 1-1 and 1-2. It was confirmed that a nitrogen-containing phosphorylate...

Abstract

A flame retardant resin composition and a molded product are disclosed. The flame retardant resin composition comprises a thermoplastic resin and a flame retardant, wherein the flame retardant contains a nitrogen-containing structure-introduced phosphorylated lignin derivative, the nitrogen-containing structure-introduced phosphorylated lignin derivative is produced by introducing a nitrogen-containing structure into a lignin derivative and adding a phosphoric acid to the lignin derivative, or by adding a phosphoric acid to a lignin derivative and introducing a nitrogen-containing structure into the lignin derivative, or by introducing a nitrogen-containing structure into and adding a phosphoric acid to a lignin derivative simultaneously, and the lignin derivative is obtained by subjecting a naturally occurring lignin to a treatment for allowing the naturally occurring lignin to be decomposed into small molecules or to be water-soluble.

Description

technical field [0001] The present invention relates to flame-retardant resin compositions and molded products which are excellent in flame retardancy and which can be suitably used in parts of image output devices such as copiers and printers and electric / electronic devices such as household appliances. Background technique [0002] Many resin parts are used in, for example, image output devices such as copiers and printers, electric / electronic devices such as household appliances, and interior parts of automobiles. For these resin parts, for the purpose of preventing the spread of fire, the resin material is required to have flame retardancy. [0003] Specifically, copiers have fixing units in their interiors that become elevated temperature states, and resin materials are also partially used around the fixing units. Further, the copying machine is equipped with a unit for generating high voltage such as a charging unit and a power supply unit such as a 100-V AC power sup...
