Embodiment 1

[0037] ⑴In parts by weight, put 100 parts of nano-cyclic phenol into a high-speed mixer at about 80°C, slowly add 0.3 parts of KH550 silane dropwise under stirring, and activate the nano-cyclic phenol. After the silane is added dropwise, Stir at a high speed of about 80° C. for 6 minutes and discharge to prepare active nano ring phenol for later use.

[0038] ⑵ In parts by weight, put 96 parts of polybutylene succinate (PBS), 2 parts of active nano-cyclic phenol, 2 parts of tributyl citrate, and 1 part of glycerin into the sugar coating machine in turn, at about 100 °C stir until the nano-ring phenol powder evenly adheres to the surface of the polybutylene succinate particles, mix evenly to prepare the nano-ring phenol masterbatch and discharge.

[0039] (3) 50 parts of corn starch, 5 parts of glycerin (glycerol), 2 parts of ethylene glycol, 7 parts of calcium carbonate, 0.8 parts of polyethylene wax, tetrakis[β-(3.5-di-tert-butyl-4-hydroxyphenyl) Propionic acid] pentaerythri...

Embodiment 2

[0042] (1) In parts by weight, put 100 parts of nano-cyclic phenol into a high-speed mixer at about 85°C, slowly add 0.8 parts of silane dropwise under stirring, and activate the nano-cyclic phenol at about 65°C. Carry out high-speed stirring for 5min and discharge to prepare active nano ring phenol for subsequent use;

[0043] (2) In parts by weight, put 98 parts of polybutylene succinate (PBS), 4 parts of active nano-cyclic phenol, 4 parts of glycerol monostearate, and 1 part of glycerin into the sugar coating machine in turn, at about 110 °C Stir-fry until the nano-ring phenol powder evenly adheres to the surface of polybutylene succinate particles, and mix evenly to prepare the nano-ring phenol masterbatch;

[0044] (3) 60 parts of corn starch, 15 parts of glycerin (glycerol), 5 parts of ethylene glycol, 10 parts of calcium carbonate, 0.4 parts of polyethylene wax, β-(3.5-di-tert-butyl-4-hydroxyphenyl)propionic acid 0.2 parts of stearyl ester, titanium dioxide (TiO 2 ) 1...

Abstract

The invention discloses a nano cyclic phenyl hydroxide modified starch / PBS biology base degradation dedicated material and a preparation method thereof. The material mainly comprises the following components: corn starch, poly butylenes succinate, glycerin, ethylene glycol, calcium carbonate, polyethylene wax, antioxygen, titanium dioxide, and a nano cyclic phenyl hydroxide master batch, wherein nano cyclic phenyl hydroxide master batch comprises the following components as poly butylenes succinate, active nano cyclic phenyl hydroxide, micro molecule plasticizer and glycerin. The preparation method is realized through the following steps: firstly feeding the corn starch, the glycerin, the ethylene glycol, calcium carbonate, the polyethylene wax, the antioxygen and titanium dioxide into an agitator for agitation at 70-90 DEG C, then feeding the poly butylenes succinate and the nano cyclic phenyl hydroxide for agitation at 105-120 DEG C, and finally mixing fully and feeding into a double-screw extruder for melt blending and extruding at 160-180 DEG C, thereby obtaining the biology base degradation dedicated material. The product made of the biology base degradation dedicated material prepared through the method has greatly improved mechanical and physical performances.

Description

technical field [0001] The invention relates to the technical field of environmental protection of plastic products, and more specifically relates to a biodegradable plastic product material and a preparation method thereof. technical background [0002] The widespread use of plastic products has brought a lot of convenience to humans, but the plastic waste that is difficult to degrade has also brought a lot of troubles to people, and in a sense, it has also brought disasters to humans. "White pollution" plastic waste is one of the biggest public hazards in the world today, and has become an important factor threatening the ecological environment. Therefore, exploring and researching environmentally friendly materials has become an important topic for the survival and development of human beings. [0003] Starch is a degradable natural polysaccharide polymer compound with abundant sources. Because of its low cost, renewable and degradable properties, and the degradation pr...
