Embodiment 1

[0014] A kind of photodegradable plastic sheet material, described plastic sheet material comprises the following raw material composition accounting for its mass percentage: polyethylene 85%, transition metal complex 3%, synthetic vegetable ester plasticizer 9%, stabilizer 2 %, polyethylene wax 1%;

[0015] The preparation method of described plastic sheet comprises the steps:

[0016] 1) Ingredients: put the above-mentioned mass percentage of each raw material into a high-speed mixer and mix evenly to obtain a mixture;

[0017] 2) Extrusion molding by extruder: Put the mixture prepared above into the extruder to extrude to obtain plastic sheet.

Embodiment 2

[0019] A kind of photodegradable plastic sheet material, described plastic sheet material comprises the following raw material composition accounting for its mass percentage: polyethylene 78%, stearate 4%, synthetic vegetable ester plasticizer 12%, stabilizer 3% , polyethylene wax 3%;

[0020] The preparation method of described plastic sheet comprises the steps:

[0021] 1) Ingredients: put the above-mentioned mass percentage of each raw material into a high-speed mixer and mix evenly to obtain a mixture;

[0022] 2) Extrusion molding by extruder: Put the mixture prepared above into the extruder to extrude to obtain plastic sheet.

Embodiment 3

[0024] A kind of photodegradable plastic sheet material, described plastic sheet material comprises the following raw material composition accounting for its mass percentage: polyethylene 85%, stearate 6%, synthetic vegetable ester plasticizer 4%, stabilizer 4% , polyethylene wax 1%;

[0025] The preparation method of described plastic sheet comprises the steps:

[0026] 1) Ingredients: put the above-mentioned mass percentage of each raw material into a high-speed mixer and mix evenly to obtain a mixture;

[0027] 2) Extrusion molding by extruder: Put the mixture prepared above into the extruder to extrude to obtain plastic sheet.

[0028] The invention discloses a photodegradable plastic sheet. By adding a photosensitizer to the polyolefin resin, the photosensitizer absorbs light energy to generate free radicals, promotes the oxidation of the polyolefin resin to achieve deterioration, and adds a plasticizer at the same time , stabilizer, dispersant and other additives, so t...

Abstract

The invention discloses a light degradation plastic sheet. The plastic sheet is prepared from, by mass, 78-85% of polyolefin resin, 3-6% of photosensitizer, 4-12% of plasticizer, 2-4% of stabilizer, 1-3% of dispersant, and the photosensitizer is one of transition metal complex, stearate, and iron N,N'-dibutyl dithiocarbamate. A preparing method of the plastic sheet includes the following steps of batching, wherein all the raw material components by the mass are put into a high-speed mixer to be mixed uniformly to obtain a mixture; extrusion molding through an extruder, wherein the prepared mixture is put into the extruder to extrude the plastic sheet. By means of the mode, the light degradation plastic sheet is excellent in light degradability and good in strength and tenacity.

Description

technical field [0001] The invention relates to the field of plastic sheets, in particular to a photodegradable plastic sheet. Background technique [0002] At present, the disclosed plastic sheets mainly include non-degradable plastic sheets made of polymer polyolefin resins such as PVC, PE, PP, PS, PET, etc. Stationery, tableware, crafts, etc. Products such as electromechanical packaging are made of non-degradable plastics, and the resulting negative environmental effects have aroused serious concern and anxiety from all walks of life. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a photodegradable plastic sheet, which can cause photochemical reaction to break and decompose macromolecular chains under sunlight irradiation. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is: provide a kind of photodegradable plastic sheet material, desc...
