Embodiment 1

[0142] Step 1, weigh the following components according to the mass ratio: 30 parts of polypropylene, 20 parts of polycaprolactone, 2 parts of maleic anhydride grafted polypropylene, 10 parts of stearic acid amine, 5 parts of erucamide, hard 0.5 part of fatty acid, 0.5 part of palmitic acid, 0.5 part of antioxidant and 0.5 part of silane coupling agent;

[0143] Step 2, put maleic anhydride grafted polypropylene, stearic acid amine, erucic acid amide, stearic acid, palmitic acid, antioxidant and silane coupling agent into mixer 1 and mix uniformly to obtain the first mixture;

[0144] Step 3, putting polycaprolactone and polypropylene into the mixer 1 and mixing with the first mixture to obtain a second mixture;

[0145] Step 4, when the central control unit 5 determines that the second mixture is mixed uniformly, the second mixture is extruded by an extruder to obtain a biodegradable plastic.

Embodiment 2

[0147] Step 1, weigh the following components according to the mass ratio: 50 parts of polypropylene, 30 parts of polycaprolactone, 5 parts of maleic anhydride grafted polypropylene, 15 parts of stearic acid amine, 10 parts of erucamide, hard 3 parts of fatty acid, 3 parts of palmitic acid, 3 parts of antioxidant, 3 parts of silane coupling agent;

[0148] Step 2, put maleic anhydride grafted polypropylene, stearic acid amine, erucic acid amide, stearic acid, palmitic acid, antioxidant and silane coupling agent into mixer 1 and mix uniformly to obtain the first mixture;

[0149] Step 3, putting polycaprolactone and polypropylene into the mixer 1 and mixing with the first mixture to obtain a second mixture;

[0150] Step 4, when the central control unit 5 determines that the second mixture is mixed uniformly, the second mixture is extruded by an extruder to obtain a biodegradable plastic.

Embodiment 3

[0152] Step 1, weigh the following components according to the mass ratio: 40 parts of polypropylene, 25 parts of polycaprolactone, 3 parts of maleic anhydride grafted polypropylene, 12 parts of stearic acid amine, 7.5 parts of erucamide, hard 2 parts of fatty acid, 2 parts of palmitic acid, 1.5 parts of antioxidant, 1.5 parts of silane coupling agent;

[0153] Step 2, put maleic anhydride grafted polypropylene, stearic acid amine, erucic acid amide, stearic acid, palmitic acid, antioxidant and silane coupling agent into mixer 1 and mix uniformly to obtain the first mixture;

[0154] Step 3, putting polycaprolactone and polypropylene into the mixer 1 and mixing with the first mixture to obtain a second mixture;

[0155] Step 4, when the central control unit 5 determines that the second mixture is mixed uniformly, the second mixture is extruded by an extruder to obtain a biodegradable plastic.

Abstract

The invention relates to a method for accelerating the biodegradation of plastics, comprising: step 1, weighing the following components according to the mass ratio: polypropylene, polycaprolactone, maleic anhydride grafted polypropylene, stearic acid amine, mustard acid amide, stearic acid, etc.; step 2, put maleic anhydride grafted polypropylene, stearic acid amine, etc. into a mixer and mix evenly to obtain the first mixture; step 3, polycaprolactone and polypropylene Put it into a mixer and mix it with the first mixture to obtain the second mixture; step 4, when the central control unit determines that the second mixture is evenly mixed, extrude the second mixture through an extruder to obtain a biodegradable plastic; thus By adjusting the rotation speed, mixing time and temperature in the mixing chamber to make the particle number and light intensity of the second mixture in the mixing chamber meet the standard, so that the second mixture in the mixing chamber can be mixed evenly, and the biodegradability can be effectively increased to speed up The rate at which plastics biodegrade.

Description

technical field [0001] The invention relates to the field of environmentally friendly biodegradable plastics, in particular to a method for accelerating the biodegradation of plastics. Background technique [0002] Plastics are polymer compounds that are polymerized from monomers through addition polymerization or polycondensation reactions. The composition and shape can be changed freely. It is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. composition. Plastic is an important organic synthetic polymer material. Because of its strong corrosion resistance, no reaction with acid and alkali, low manufacturing cost, durability, waterproof, light weight and strong plasticity, it is widely used in various industries. [0003] However, plastics are easy to age, and discarded plastics cannot be degraded naturally for decades or even hundreds of years, leading to the destruction of the ecological environment and threa...
