Embodiment 1

[0035] The foam net material consists of 60 parts of PBAT, 10 parts of PBS, 30 parts of PGA, 1 part of compatibilizer styrene-glycidyl methacrylate, 1 part of antihydrolysis agent polycarbodiimide, bis(2,4 - 0.4 parts of di-tert-butylphenyl) pentaerythritol diphosphite, 1 part of organic nucleating agent TMC-200, 1 part of TMC-306, 4 parts of inorganic nucleating agent talcum powder, 0.3 parts of lubricant ethylene bis stearamide 0.2 parts of anti-shrinkage agent monoglyceride, 1 part of antioxidant 1010, and 2 parts of white masterbatch.

[0036] The preparation process of the foam net is to mix PBAT, PBS, PGA, compatibilizer, anti-hydrolysis agent, nucleating agent, lubricant, anti-shrinkage agent, antioxidant, and color masterbatch evenly, and then mix it in a special double-layer for biodegradable plastics. The screw extruder is melted and mixed, and granulated to obtain a foamed modified base material. The temperature of zone 1-9 of the extruder is 160°C, 180°C, 200°C, 2...

Embodiment 2

[0039]The foam net material components are 60 parts of PBAT, 20 parts of PBS, 20 parts of PGA, 0.8 parts of compatibilizer ethylene-methyl acrylate-glycidyl methacrylate, 0.8 parts of anti-hydrolysis polycarbodiimide, cyclic 0.4 part of pentapentane tetrayl bis (2,6-di-tert-butyl-4-methylphenyl phosphite), 1 part of organic nucleating agent TMC-200, 1 part of TMC-300, inorganic nucleating agent carbonic acid Calcium 3 parts, lubricant erucamide 0.3 part, anti-shrinkage agent monoglyceride 0.2 part, antioxidant 1790 0.8 part, pink masterbatch 2 parts.

[0040] The preparation process of the foam net is to mix PBAT, PBS, PGA, compatibilizer, anti-hydrolysis agent, nucleating agent, lubricant, anti-shrinkage agent, antioxidant, and color masterbatch evenly, and then mix it in a special double-layer for biodegradable plastics. The screw extruder is melted and mixed, and granulated to obtain a foamed modified base material. The temperature of zone 1-9 of the extruder is 160°C, 180...

Embodiment 3

[0043] The foam net material components are 60 parts of PBAT, 30 parts of PBS, 10 parts of PGA, 0.6 parts of compatibilizer styrene-acrylonitrile-glycidyl methacrylate, 0.6 parts of anti-hydrolysis polycarbodiimide, bis( 0.2 parts of 2,4-di-tert-butylphenyl) pentaerythritol diphosphite, 1.5 parts of organic nucleating agent TMC-306, 2 parts of inorganic nucleating agent silicon dioxide, 0.3 parts of lubricant stearic acid, anti-shrinkage agent 0.2 part of monoglyceride, 0.6 part of antioxidant 1024, 2 parts of yellow masterbatch.

[0044] The preparation process of the foam net is to mix PBAT, PBS, PGA, compatibilizer, anti-hydrolysis agent, nucleating agent, lubricant, anti-shrinkage agent, antioxidant, and color masterbatch evenly, and then mix it in a special double-layer for biodegradable plastics. The screw extruder is melted and mixed, and granulated to obtain a foamed modified base material. The temperature of zone 1-9 of the extruder is 160°C, 180°C, 200°C, 210°C, 220...

Abstract

The invention belongs to the technical field of foaming materials, and particularly relates to a full-biodegradable foaming net and a preparation method thereof. The full-biodegradable foaming net is prepared from, by mass, 40-85 parts of PBAT, 10-30 parts of PBS, 5-30 parts of PGA, 0.4-1 part of a compatibilizer, 0.4-1 part of an anti-hydrolysis agent, 0.8-2 parts of an organic nucleating agent, 2-4 parts of an inorganic nucleating agent, 0.3-0.5 parts of a lubricant, 0.2-0.3 parts of an anti-shrinking agent, 0.4-1 parts of an antioxidant, and 2 parts of color master batch. The foaming net material provided by the invention has the characteristic of full-natural-domain degradation, particularly has degradation capacity in a water body in a marine environment, and can realize regulation and control of degradation time, so that the shelf life of a foaming net product is prolonged, and different requirements of the product are met.

Description

technical field [0001] The invention belongs to the technical field of foam materials, and in particular relates to a fully biodegradable foam net and a preparation method thereof. Background technique [0002] At present, various cushioning and shock-absorbing foam net products on the market are mostly made of polyethylene, and most of them are disposable products, which are discarded after use and cannot be recycled, causing white pollution. The degradation process of polyethylene is quite slow, and the microplastics produced during the degradation process have caused extensive and serious harm to the entire ecosystem including humans through the ocean, rivers, lakes, groundwater and other environments. [0003] For fully biodegradable foaming materials and products, relevant reports are as follows after retrieval: [0004] The CN2019106015785 patent document discloses a 100% compostable and fully degradable environmental protection net, but it is limited to an ordinary e...
