Description

Technical Field

[0001] The invention belongs to the field of decorative materials, and in particular relates to a plant-based floor protective film and a preparation method thereof. Background Art

[0002] In typical solid wood floors, a difficult-to-reach, often overlooked blind spot forms between the floor, mat, and flooring. Underneath the floor, this blind spot creates an ideal environment for cockroaches and ants to congregate. Furthermore, common insecticides cannot penetrate the floor from the outside to be effective, creating a haven and a haven for these insects and ants. Over time, the accumulation of dust, dander, food debris, and other substances, coupled with temperature and humidity fluctuations, creates a breeding ground for allergenic pathogens, mold, bacteria, fungi, pet fleas, insect eggs, pests, and other toxic and harmful substances, creating a significant source of pollution. While applying traditional insecticides under the floor is effective in preventing pests, they carry inherent toxic side effects. Even if they pass agricultural testing and obtain production approval, they are restricted to agricultural and forestry production and other specialized uses and are not permitted in domestic settings. The hazards of using insecticides, especially for pregnant women, children, and infants with weakened immune systems, must be given due attention. Especially when these drugs drift onto the ground through the gaps, their harm is even more serious, so it is urgent to improve the environment under the home floor. Summary of the Invention

[0003] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a plant-based floor protective film and a preparation method thereof.

[0004] Technical solution: A plant base floor protective film, which is composed of the following components in parts by weight: 12-18 parts of white pyrethrum, 78-86 parts of PVC powder, 2-4 parts of camphor, 32-41 parts of matting powder, 27-38 parts of plasticizer, 6-9 parts of wormwood, 12-16 parts of CaZn stabilizer, 3-5 parts of Sichuan pepper, 2-6 parts of enhancer, 1-5 parts of costus root, and 4-6 parts of sulfur.

[0005] As an optimization: the plant-based floor protective film is composed of the following components in parts by weight: 14 parts of white pyrethrum, 83 parts of PVC powder, 3 parts of camphor, 37 parts of matting powder, 34 parts of plasticizer, 8 parts of mugwort, 14 parts of CaZn stabilizer, 4 parts of pepper, 5 parts of enhancer, 3 parts of costus root, and 5 parts of sulfur.

[0006] A method for preparing the plant-based floor protective film comprises the following steps:

[0007] Step 1, respectively measuring the following raw materials by mass, specifically: 12-18 parts of white pyrethrum, 78-86 parts of PVC powder, 2-4 parts of camphor, 32-41 parts of matting powder, 27-38 parts of plasticizer, 6-9 parts of wormwood, 12-16 parts of CaZn stabilizer, 3-5 parts of Sichuan pepper, 2-6 parts of enhancer, 1-5 parts of costus root, and 4-6 parts of sulfur;

[0008] Step 2: Put the PVC powder and matting powder into a high-stirring mixer for mixing. The high-stirring mixer is added with a spray injection method for atomization spraying. Then, the plasticizer, CaZn stabilizer and reinforcing agent are added to the high-stirring mixer for mixing. The high-stirring mixing processing temperature is: 86-96°C. Other different substances are added through the above-mentioned staged method so that the various raw materials can absorb each other evenly and mix at high speed. When the internal temperature reaches 96°C, turn to low speed and discharge into the powder cold mixer for cold stirring. This will not affect the complete absorption of the plasticizer by the PVC powder and plasticize evenly.

[0009] Step 3: When cold stirring in the powder cold mixer, add chilled water, fully cool and evenly cool to 62°C, discharge into the middle barrel, and then transport to the discharge barrel through the screw conveyor;

[0010] Step 4: Add the mixture in the above-mentioned discharge barrel into the reciprocating extruder. The screw and the barrel will reciprocate to fully shear the mixture, plasticize and mix it evenly, and the materials will rub and extrude each other to enhance plasticization. The low molecular weight in the mixture will be extracted and emptied by the vacuum pump of the main machine to reduce the odor of the finished product.

[0011] As an optimization: the reciprocating extruder in the step 4 is divided into the following five zones, and the temperature distribution is as follows: zone 1 80°C, zone 2 160°C, zone 3 160°C, filter die 160°C, screw 160°C, and the plasticized material is evenly filtered and extruded.

[0012] Beneficial effects: The specific advantages of the present invention are as follows: the present invention adds a reciprocating extruder, which ensures uniform plasticization; smoke-free raw materials are added to the formula of the floor film, which reduces pollution and has better environmental protection performance; the present invention is a pure plant preparation, green and pollution-free, and the floor protective film can not only inhibit the harm of pests, but also has good effects, low dosage, is harmless to humans and animals, and has no pollution or irritation.
