Abstract

The invention provides a modified polybutylene succinate nanocomposite material. The modified polybuthylenesuccinate nanocomposite material comprises 100 parts of polybutylene succinate, 1 to 5 parts of octaphenylsilsequioxane, 0 to 15 parts of modified loofah fibers, 0.2 to 1 part of a heat stabilizer, 0.5 to 2 parts of a plasticizer and 0.5 to 2 parts of a flame retardant. A preparation method of the nanocomposite material comprises 1, drying polybutylene succinate at a temperature of 50-80 DEG C for 3-5h, 2, mixing the polybutylene succinate and octaphenylsilometasiloxane for 3-5min and then adding the modified loofah fibers, plasticizer, flame retardant and heat stabilizer into the mixture and carrying out mixing for 5 to 10min, and 3, carrying out granulation and injection molding to obtain the nanocomposite material. The modified polybutylene succinate nanocomposite material provided by the technical proposal of the invention has excellent mechanical properties and effectively improves the softness and rigidity of the polybutylene succinate product.

Description

technical field [0001] The present invention relates to the field of degradable resins, in particular to a modified polybutylene succinate nanocomposite material and a preparation method thereof, in which octaphenyloctasilsesquioxane terephthalate is related to polybutylene succinate Improve. Background technique [0002] Polybutylene succinate (PBS) is a resin obtained by condensation polymerization of succinic acid and butanediol. It is milky white, odorless and tasteless, and is easily decomposed by various microorganisms in nature or enzymes in animals and plants. , metabolism, and finally decomposed into carbon dioxide and water, is a biocompatible and biodegradable aliphatic polyester. [0003] Due to its unique properties, those skilled in the art have carried out research on it, and achieved remarkable results so far. Among them, CN104356617A discloses a fully biodegradable plastic, including polylactic acid, modified polybutylene succinate, filler, coupling agent,...
