Abstract

The invention discloses nitrogenous nutritional biodegradable modified resin as well as a preparation method and application thereof. The biodegradable modified resin is prepared from the following components in parts by mass: 60 to 90 parts of biodegradable resin, 5 to 25 parts of oxadiamide, 5 to 20 parts of inorganic filling powder, 0.5 to 2 parts of coupling agent, 0.3 part of antioxidant 1076, 0.2 part of antioxidant 626, 0.2 part of erucyl amide and 0.3 part of white oil. The biodegradable modified resin disclosed by the invention can be used for processing and manufacturing downstream film bag products. According to the nitrogen-containing nutritional biodegradable modified resin disclosed by the invention, an oxalyl diamine filling component which can slowly release nitrogen nutrients and is safe and environment-friendly is innovatively added into the biodegradable modified resin, and the nitrogen nutrients necessary for microorganism breeding and crop growth are provided in a degradation process, so that the breeding of microorganisms and the growth of crops are promoted; therefore, the degradation process of the biodegradable plastic is obviously accelerated, the growth of crops is promoted, and the method has important significance in promoting the biodegradable plastic to play a positive role in the white pollution treatment process.

Description

technical field [0001] The invention belongs to the technical field of biodegradable resin modification, and relates to a blending and filling modified biodegradable modified resin, more specifically to a nitrogen-containing nutritional biodegradable blending and filling modified resin and a preparation method thereof . Background technique [0002] At present, the problem of plastic pollution is intensifying, and the almost permanent pollution of the natural environment has become an urgent global crisis facing mankind. Biodegradable plastics, because of their excellent performance, can be completely decomposed into carbon dioxide (CO 2 ) or / and methane (CH 4 ), H 2 O and the mineralized inorganic salts of its elements are in line with the current global environmental protection trend and have become an effective way to control plastic pollution. [0003] At present, the biodegradable plastics that have been widely used mainly include polybutylene terephthalate-adipate ...
