Embodiment 1

[0035] The raw materials of the degradable master batch include ferrocene, calcium carbonate, citric acid, dispersant and photosensitizer, and the components of the raw materials are: 11% of ferrocene, 76% of calcium carbonate, lemon Acid 4%, dispersant 4% and photosensitizer 5%. The percentage of each component in Example 1 is the percentage of the weight of each component to the total weight of the masterbatch. The plastic film made of the masterbatch listed in Example 1 and polyethylene with the same weight was tested, and the test results are shown in Table 1.

[0036] Table I

[0037]

[0038] It can be seen from Table 1 that although the degradation rate is faster than that of the prior art, and it can be degraded no matter under sunlight conditions (illumination) or under water vapor conditions (humidity) or under microbial conditions (soil), realizing However, it can be concluded from Table 1 that the actual cracking under the action of air and light is still not ...

Embodiment 2

[0040] The raw materials of the degradable master batch include ferrocene, calcium carbonate, citric acid, dispersant and photosensitizer, and the components of the raw materials are: 12% of ferrocene, 72% of calcium carbonate, lemon 8% acid, 4% dispersant and 4% photosensitizer.

[0041]The plastic film made of the masterbatch listed in Example 2 and polyethylene with the same weight was tested, and the test results are shown in Table 2.

[0042] Table II

[0043]

[0044] It can be seen from Table 2 that the cracking is still slow under light and air conditions, and finally although it can be degraded simultaneously under various conditions, the degradation time is long and the efficiency is low, resulting in poor degradation effect.

Embodiment 3

[0046] The raw materials of the degradable master batch include ferrocene, calcium carbonate, citric acid, dispersant and photosensitizer, and the components of the raw materials are: 10% of ferrocene, 74% of calcium carbonate, lemon Acid 6%, dispersant 4% and photosensitizer 6%.

[0047] The plastic film made of the masterbatch listed in Example 3 and polyethylene with the same weight was tested, and the test results are shown in Table 3.

[0048] Table three

[0049]

[0050] It can be seen from Table 3 that the plastic film formed by adding the masterbatch in Example 3 to polyethylene is the most stable and rapid during cracking, and the cracked fragments are uniform in size, and the degradation time in soil is short, fast and efficient.

[0051] A plastic film containing degradable master batches, the raw material of the plastic film includes a compound of polyethylene and degradable master batches, and the weight ratio of the polyethylene and the degradable master bat...

Abstract

The invention relates to degradable master batch, a plastic film comprising the same and a preparation method of the plastic film, and relates to the field of plastic processing, in particular relatesto the degradable master batch, the plastic film comprising the same and the preparation method of the plastic film. The degradable master batch can be degraded in various modes, and is high in degrading speed and high in efficiency. Raw materials of the degradable master batch contain the following components in percentage by weight: 8-12% of ferrocene, 72-76% of calcium carbonate, 4-8% of citric acid, 1-5% of a dispersant and 4-8% of a photosensitizer. The dispersant is prepared by compounding one or more of barium stearate, zinc stearate, calcium stearate, cadmium stearate, magnesium stearate and copper stearate. The degradable master batch accelerates the plastic film to be degraded multidimensionally while the degrading speed is increased, so that the degrading conditions of the plastic film are further broadened, and the degradable master batch can be degraded in various modes, and is high in degrading speed and high in efficiency.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a degradable master batch, a plastic film containing the master batch and a preparation method of the plastic film. Background technique [0002] Plastic bags and plastic wrap are daily necessities in people's lives. They are generally made of polymer compounds such as polyethylene. Although plastics are recyclable garbage, due to the excessive use of plastics in life and the low recycling price of plastics, resulting in The recycling of plastics is not in place. Due to the use of polymer materials, the molecular structure is stable, and it is difficult to degrade under natural conditions, causing huge pollution to the environment and causing great harm to the living environment of human beings. [0003] In response to this problem, an invention patent application (CN106046490A, an easily degradable environmentally friendly plastic bag and its preparation method) disclosed by th...
