Definitions
- the present invention relates to a biodegradable resin composition containing a large amount of an organic filler.
- the present invention can provide a good biodegradable resin molded product without significantly impairing the mechanical properties of the resin even when a large amount of the organic filler is added. By enabling easy addition, a product with excellent economic efficiency can be obtained.
- a large amount of, for example, 100 parts by weight or more of an organic filler and 3 to 10 parts by weight of rosin are charged into a general-purpose mixing stirrer and uniformly mixed.
- the mixture may be formed into a molded product by a general-purpose extruder, injection molding machine, press molding machine, calender molding machine, or the like.
- biodegradable resin used herein means polylactic acid obtained from lactic acid obtained from natural products, water-soluble polybutyl alcohol as a raw material, cellulose acetate-based cellulose-modified one, aliphatic ester-based one, etc. Polylactones and various aliphatic ester-based copolymers, biopolyesters (polyhydroxyalkanoates) made by microorganisms decomposing natural products, natural rubber, etc.
- organic filler includes trees, grass powder obtained by dry-barreling bark and hay, grain powder obtained by crushing cereals and rice husks, crushed waste paper, and the like. Cool If the particle size is 1000 microns or less, it can be sufficiently mixed and kneaded, but preferably 500 microns or less.
- the rosin used herein refers not only to natural rosin but also various modified derivatives thereof, as well as synthetic rosins such as aromatic petroleum resins derived from petroleum and various derivatives thereof. Such rosin is added in an amount of 0.3 to 10 parts by weight based on 100 parts by weight of the biodegradable resin. Is not preferred. Comparative Example 1, Examples 1, 2,
- Example 3 The composition containing 0.5 gram of rosin took more than 15 minutes to completely homogenize, but a 0.5 mm thick sheet could be removed. The composition containing 3.0 g of rosin was completely homogeneously mixed within 6 minutes, and a sheet having a thickness of 0.5 mm could be taken out. Comparative Examples 2 and 3, Example 3
- biodegradable polyester resin (trade name: Bisai Nore, manufactured by Showa Polymer Co., Ltd.), 600 g of kenaf powder (average particle size: 500 microns), and 600 g of synthetic rosin (Yasuhara Chemical, trade name: Mighty Ace G-1) 25) were added in 0, 3.0, and 10 grams, respectively, and mixed by a mixer (10 L Henschel mixer manufactured by Mitsui Miike Co., Ltd.) for 5 minutes. The cylinder temperature was 180 and the die temperature was 170 °. It was put into a 40 mm extruder (FS-40 made by Ikegai) set in C.
- FS-40 40 mm extruder
- the composition without rosin was not discharged at all from the sliding die hole in the cylinder. Although the composition containing 3.0 g of rosin was discharged from the die hole, it did not become a strand in a ragged state and could not be granulated. The composition containing 10 g of rosin was extruded in the shape of a strand in a die hole, and uniform granulation was achieved by a rotator.
