Problems solved by technology

[0002] Waste plastic is plastic waste generated in people's life, and most of it is buried and incinerated, which is easy to cause white pollution to the environment. As people's awareness of environmental protection increases, garbage classification is gradually implemented. Waste plastic is recyclable. After sorting out the waste plastics, the recycling method should be considered. At present, the main recycling method for waste plastics in my country is to clean the waste plastics first, and then crush, melt and granulate them to prepare them into plastic granules. Then plastic granules are used to prepare asphalt, pipes, plastic bags, garbage bags and foam, etc., but because waste plastic granules are directly added to product raw materials during the preparation process, waste plastic itself contains many unclear components , and the performance parameters of waste plastics will decrease significantly after long-term use, so directly adding waste plastic particles to product raw materials will affect the performance parameters of the product and affect the practicability of the product
[0003] The existing patent document CN105295415A discloses a degradable garbage bag produced by using waste plastics and its preparation method. The waste plastics are pulverized and then the raw materials of the garbage bags are added to the garbage bags to be fully melted to prepare the garbage bags. The raw materials added during the preparation process There are many types, which obviously increases the preparation cost of garbage bags. Although it is made of waste plastics, the cost is significantly higher than that of ordinary garbage bags, which is unacceptable to ordinary consumers and will also affect the further recycling of waste plastics.

Embodiment 1

[0028] A method for modifying waste plastics, comprising the steps of:

[0029] (1) Cleaning: Cut the waste plastics to 4~6cm, wash the sundries with clean water first, and then put them in the cleaning solution. The cleaning solution is composed of the following raw materials in parts by weight: water 900, sodium chloride 17. Potassium permanganate 3, sodium dioctyl succinate sulfonate 6, ultrasonically cleaned at 35°C and 31kHz for 30 minutes, and then rinsed with clean water, can not only remove stains on the surface of waste plastics, but also sterilize waste plastics, To prevent waste plastics from carrying germs and causing harm to the human body and the environment, waste plastics must be cleaned;

[0030] (2) Crushing: Crush the cleaned waste plastics to 2~4mm, evenly spray the acetic acid solution with a volume fraction of 1.3%, the added amount is 5% of the weight of the waste plastics, adjust the temperature to 41°C, and irradiate with ultraviolet light for 30 hours...

Embodiment 2

[0037] A method for modifying waste plastics, comprising the steps of:

[0038] (1) Cleaning: Cut the waste plastic to 4~6cm, wash the sundries with clean water first, and then put it in the cleaning solution. The cleaning solution is composed of the following raw materials in parts by weight: water 950, sodium chloride 18. Potassium permanganate 3~54, sodium dioctyl succinate sulfonate 7, ultrasonically cleaned at 38°C and 32kHz for 35 minutes, and then rinsed with clean water, can not only remove the stains on the surface of waste plastics, but also clean the waste plastics Disinfection, to prevent waste plastics from carrying germs and causing harm to the human body and the environment, waste plastics must be cleaned;

[0039] (2) Crushing: Crush the cleaned waste plastics to 2~4mm, evenly spray the acetic acid solution with a volume fraction of 1.5%, the added amount is 6% of the weight of the waste plastics, adjust the temperature to 42°C, and irradiate with ultraviolet l...

Embodiment 3

[0046] A method for modifying waste plastics, comprising the steps of:

[0047] (1) Cleaning: Cut the waste plastics to 4~6cm, wash the sundries with clean water first, and then put them in the cleaning solution. The cleaning solution is composed of the following raw materials in parts by weight: water 1000, sodium chloride 19. Potassium permanganate 5, sodium dioctyl succinate sulfonate 8, ultrasonically cleaned at 40°C and 33 kHz for 40 minutes, and then rinsed with clean water, can not only remove stains on the surface of waste plastics, but also sterilize waste plastics, To prevent waste plastics from carrying germs and causing harm to the human body and the environment, waste plastics must be cleaned;

[0048] (2) Crushing: Crush the cleaned waste plastics to 2~4mm, evenly spray the acetic acid solution with a volume fraction of 1.7%, the added amount is 7% of the weight of the waste plastics, adjust the temperature to 43°C, and irradiate with ultraviolet light for 36 hou...

Abstract

The invention mainly relates to the technical field of plastics processing, and discloses methods for modification and application of waste plastics. The method for modification of the waste plasticsincludes the steps: (1) cleaning, (2) crushing, and (3) modification, and the method for application of a mulch film which is prepared from the modified waste plastics includes the following steps: (1) melting the main material, (2) preparing the mulch film material, and (3) performing molding. According to the methods for modification and application of the waste plastics, the strength and film-forming properties of the waste plastics can be enhanced through treatment and modification of the waste plastics, and reuse is facilitated; and when the modified waste plastics is applied to preparation of the mulch film, the raw materials are simple, the cost is saved, the prepared mulch film has high strength and high durability, and the abandoned residual mulch film can be degraded, so that secondary pollution to soil and the environment is avoided.
