Preparation method of agricultural plastic bowl soft tray material with aging resistance and wear resistance

Abstract

The invention discloses a preparation method of an agricultural plastic bowl soft tray material with aging resistance and wear resistance, and belongs to the technical field of high polymer materials.According to the reparation method of the agricultural plastic bowl soft tray material with aging resistance and wear resistance, cultivated seedlings have good quality and are not easily attacked bydiseases, the seedling field ratio can be substantially increased, seedling rising can be promoted to intensive and professional development, the management is convenient, and the seedling raising cost is reduced. The agricultural plastic bowl soft tray material with aging resistance and wear resistance is favorable for reducing labor cost and reducing labor intensity, can be repeatedly used, hashigh and heat resistance, reduces production cost, has good heat stability and ageing resistance, simplifies the planting process, provides powerful measures for cost-saving, yield-increasing and synergistic planting, and has good overall performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a method for preparing an agricultural aging-resistant and wear-resistant plastic bowl floppy disk material. Background technique [0002] Plastic pot sports seedling transplanting technology is a labor-saving, labor-saving, high-yield, stable production, and a new cultivation technology with significant economic benefits. It has the advantages of convenient centralized management, strong seedlings, less pests and diseases, no root damage, slow seedling planting, high survival rate, seed saving, early maturity, staggered sales, peak production period, increased production, increased income of more than 560 yuan, labor saving, Time-saving and other advantages are very popular among farmers.

AI Technical Summary

Problems solved by technology

The molding and material of the bowl floppy disk, the most suitable molding process for the production of the bowl floppy disk, adopts blister molding, and the vacuum blister molding process is prone to perforation, which affects the molding effect, and the bottom of the bowl is thin, which does not meet the agricultural requirements, and the production efficiency Also compared, improved production materials

Plastic floppy disks currently on the market are mostly made of poor weather resistance polyethylene, polypropylene, and polyvinyl chloride with poor heat resistance. As for plastic floppy disks, they should be made of suitable and economical materials. In terms of plastic wrap, polyethylene and polypropylene bowl floppy disks are slightly inferior in toughness and strength compared to PVC bowl floppy disks, and are easy to break

However, PVC floppy disks are not suitable for the cultivation of oil-containing crops, and cannot be heated at high temperatures. Due to the poor heat resistance of PVC materials, they decompose and release hydrogen chloride gas when exposed to high temperatures. Plasticizers DEHP and DOP are usually added. (dioctyl phthalate), and a small amount of heat stabilizer to reduce the processing temperature. PVC itself is a hard material. After adding plasticizer, it will become soft and easy to bend, so it has its application. Agents DEHP and DOP have hepatotoxicity and can cause cancer. Representative plasticizers are easy to accumulate in organisms and are generally colorless oily viscous liquids. The chemical structure determines their basic physical and chemical properties and behavior after entering the environment. These compounds have The characteristics of high fluidity, low water solubility, non-volatile, low freezing point and long residual time in the environment have general toxicity and special toxicity, such as teratogenicity, mutagenicity or carcinogenic activity, especially for causing abnormal human reproductive function. Concern, DOP has a mutagenic effect on germ cells, plays an estrogen-like role in the body, and interferes with endocrine, so it is classified as an environmental hormone

The U.S. National Environmental Protection Agency EPA lists DEHP and DOP as toxic pollutants for priority control, and my country also includes DEP, DMP and DOP in the blacklist of environmental priority control pollutants, and the above materials are not wear-resistant, have poor low-temperature performance, and are easily tearing, short service life, increased production costs

Existing plastic bowl floppy disk materials cannot meet the requirements of existing production and life. Those skilled in the art urgently need to develop a plastic bowl floppy disk material with anti-aging and excellent comprehensive performance to meet the vast agricultural production and life and applications.
