Definitions

  • the present invention relates to a cellulose acetate resin composition. Specifically, the present invention relates to a cellulose acetate resin composition used for melt molding.
  • Patent Document 1 discloses a biodegradable sheet comprising an acetate composition containing cellulose acetate and polyoxyethylene glycol.
  • Patent Document 2 discloses a biodegradable film or sheet containing cellulose acetate having an acetyl group substitution degree of 2.3 to 2.7 and a biodegradable plasticizer as main element components.
  • This plasticizer includes (1) a compound represented by (1) H 5 C 3 (OH) 3-n (OOCCH 3 ) n (0 ⁇ n ⁇ 3), and (2) glycerin alkylate and ethylene glycol alkylate.
  • compositions disclosed in Patent Documents 1-3 are melt-molded at a temperature exceeding 200 ° C. to obtain a sheet having a thickness of more than 100 ⁇ m. If the melting temperature exceeds 200 ° C., there is a problem that coloring occurs due to thermal decomposition of cellulose acetate.
  • the resin composition of Patent Document 4 is melt-spun at a temperature of 200 ° C. or lower, and cellulose acetate having a low degree of substitution is used in this resin composition.
  • the cellulose acetate resin composition according to the present invention contains a cellulose acetate (A) having a total acetyl substitution degree of 2.60 or less, a filler (B), and a plasticizer (C).
  • the filler (B) is one or more selected from the group consisting of the following (b1)-(b4).
  • the content of the cellulose acetate (A) in the entire resin composition is 45% by mass or more and 90% by mass or less, the total content of the filler (B) is 5% by mass or more and 50% by mass or less, and the plasticizer.
  • the total content of (C) is 5% by mass or more and 35% by mass or less.
  • the total degree of acetyl substitution of cellulose acetate (A) is 2.0 or more and 2.60 or less.
  • the glycerin ester-based plasticizer (c1) is a compound in which at least one hydroxyl group of glycerin is esterified, and is preferably a compound esterified with a carboxylic acid having a molecular weight of 150 or less, more preferably 130 or less. ..
  • the amount of sulfuric acid component of cellulose acetate (A) is preferably 350 ppm or less, more preferably 300 ppm or less, and particularly preferably 250 ppm or less. The smaller the amount of sulfuric acid component is, the more preferable it is, but the lower limit is 30 ppm.
  • the sulfuric acid component is a concept including a conjugated sulfuric acid contained in the cellulose acetate (A), a free sulfuric acid, and a sulfate neutralized by the addition of a base.
  • the bound sulfuric acid includes a sulfuric acid group ester-bonded to cellulose acetate (A) and a sulfuric acid component bonded as a sulfonic acid group.
  • the amount of sulfuric acid component is determined by heating cellulose acetate (A) at 1300 ° C., trapping sublimated sulfite gas in a 10% hydrogen peroxide solution, titrating with an aqueous sodium hydroxide solution, and then converting to sulfuric acid.
  • the filler (B) and the plasticizer (C) and the cellulose acetate (A) are more uniformly and in a short time, and the obtained kneaded product is homogenized, so that the melt fluidity And a resin composition with improved processing accuracy can be obtained.
  • the present invention relates to a melt-molded article using the above-mentioned cellulose acetate resin composition.
  • the molded product obtained by melt-molding the resin composition of the present disclosure has no coloring due to a thermal decomposition product and has high marine biodegradability.
  • the film of the present disclosure may be obtained by the inflation method.
  • the inflation method it is possible to form a film in the form of a tube. By fusing this tube with the fusing seal, a bag with a handle can be easily formed.
  • Comparative Examples 1 and 4 In Comparative Examples 1 and 4, the cellulose acetate shown in Table 5 below was directly subjected to the seawater biodegradation test described later without performing melt-kneading.
  • the resin composition described above can be applied to various fields using melt molding and further melt forming.
