Embodiment 1

[0026] Biodegradable plastic masterbatch raw materials (parts by weight): 30 parts of low-density polyethylene, 30 parts of bentonite, 10 parts of chlorinated paraffin, 1.5 parts of epoxy butyl stearate, tetraisopropyl di(dioctyl phosphite) 0.2 parts of titanate, 0.6 parts of dispersant, and 1.5 parts of antioxidant.

[0027] The dispersant is obtained by uniformly stirring and mixing calcium arachidate, zinc stearate and zinc myristate in a mass ratio of 1:1:1.

[0028] The antioxidant is obtained by uniformly stirring and mixing 2,6-di-tert-butyl-p-cresol, tert-butylhydroquinone and ethoxyquinoline at a mass ratio of 1:1:1.

[0029] Preparation of biodegradable plastic masterbatch:

[0030] (1) take each component according to weight ratio;

[0031] (2) Add low-density polyethylene, bentonite, chlorinated paraffin, epoxy butyl stearate, tetraisopropyl bis(dioctyl phosphite) titanate, dispersant, and antioxidant into the high-speed mixer Mixing, the mixing speed is 86 rpm,...

Embodiment 2

[0034] It is basically the same as Example 1, except that the dispersant is obtained by stirring and mixing zinc stearate and zinc myristate at a mass ratio of 1:1. Obtain the biodegradable plastic masterbatch of embodiment 2.

Embodiment 3

[0036] It is basically the same as Example 1, except that the dispersant is obtained by stirring and mixing evenly calcium arachidic acid and zinc myristate at a mass ratio of 1:1. Obtain the biodegradable plastic masterbatch of embodiment 3.

Abstract

The invention discloses a biodegradable plastic master batch. The biodegradable plastic master batch is prepared from, by weight, 20-40 parts of low-density polyethylene, 20-40 parts of bentonite, 5-15 parts of chlorinated paraffin, 1-3 parts of butyl epoxy stearate, 0.1-1 part of tetraisopropyl (dioctyl phosphate) titanate, 0.1-1 part of dispersing agent and 1-2 parts of antioxidant. The providedbiodegradable plastic master batch has the advantages that the production cost is low, the preparation process is simple, the degradation property is good, the biodegradable plastic master batch hasa good mechanical property, fire resistance and a antibacterial property, and the degradation property accords with environment-friendly requirements.

Description

technical field [0001] The invention relates to the technical field of degradable plastic raw materials, in particular to a biodegradable plastic masterbatch. Background technique [0002] With the wide application of agricultural mulch film, the output of cotton, tobacco, and crops has increased significantly. However, due to the non-degradable plastic residues in the farmland, the soil compacted and caused new "white pollution". In addition, the amount of plastic waste in the field of life and shopping has also increased year by year, which has caused the disaster of "plastic waste" and caused environmental pollution. Ecological balance; At the same time, due to the gradual reduction of petroleum resources and non-renewable petroleum resources, the plastics industry is increasingly in short supply, which limits the development of the plastics industry. [0003] Biodegradable plastics refer to a class of plastics that are degraded by the action of naturally occurring micro...
