Description
Technical Field
The invention relates to the technical field of agriculture and horticulture, in particular to a PE (polyethylene) lawn-protecting cloth with a long-acting anti-aging function.
Background
In the existing agricultural planting of crops, weeds are easy to grow in the outer gap area of the planted crops and the mutual spacing area of fruit trees, the fertilizer efficiency attraction and growth of the crops are influenced, the current proposal advocate green planting is adopted, manual weeding is adopted, at least four times are needed in one year, and the investment of labor cost is increased.
However, the existing agricultural mulching film is poor in sun-shading effect, water-proof and air-proof, soil respiration is affected, the ground cannot go underwater, the root of the plant can be rotten when the ground cannot go upward, and yield is affected; if the pesticide is used for weeding, the pesticide has damage and influence on human bodies, crops, soil and the like. The agricultural film has short service cycle, generally can be used for less than one year, a large amount of manual work is required to be invested to clean the ground waste film every year, otherwise, the waste film is mixed into the soil, the soil structure can be influenced for a long time, and the environment pollution can be influenced due to the unclean treatment of the waste film; the existing agricultural film is easy to damage, irreversible, and has small natural risk resistance and the like in the using process. The existing woven grass-proof ground fabric on the market can obtain better water seepage and air permeability, but has poor ageing resistance after being exposed to sunlight for a long time, and the service life of the ground fabric is generally not more than 3 years.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the PE straw-proof cloth with the long-acting anti-aging function solves the problems that the existing agricultural mulching film is poor in anti-aging performance, short in service life, high in labor cost for frequently cleaning and replacing the agricultural mulching film and capable of polluting the environment.
The invention is realized by the following technical scheme:
the PE straw-proof ground fabric with the long-acting anti-aging function comprises the following raw materials in percentage by mass:
further, the color master batch comprises the following raw materials:
further, the anti-aging auxiliary agent comprises the following raw materials:
further, the light stabilizer adopts a mixture of LS770 and N539; the antioxidant is one or a mixture of more of antioxidant 1010, antioxidant CA and antioxidant TNP; the lubricant is a mixture of glyceryl stearate and polyethylene wax.
Further, the filling master batch comprises the following raw materials:
further, the coupling agent adopts a mixture of SCA1503 and KH 560; the dispersing agent adopts ethylene-acrylic acid copolymer; the lubricant adopts glyceryl stearate.
The invention has the following advantages and beneficial effects:
1. the using period of the agricultural film is as short as one year, after the agricultural film is used, the waste film is collected every year, otherwise the waste film is mixed into soil to gradually influence the soil structure and pollute the environment, and the manual cleaning increases the manual input; the invention greatly improves the natural performances of the grass-proof cloth such as high temperature resistance, radiation aging resistance and the like by optimizing and improving the formula design, has strong weather resistance, can be repeatedly used for 5 to 10 years after being put into use once, and has the characteristics of one-time use and benefit for many years;

3. in winter, the grassland cloth is covered to keep the temperature of the earth surface, so that the soil temperature can be increased by 5-8 ℃, the growth and development of the roots of the plants are promoted, the growth period of the plants is shortened, the precocity of vegetables and fruits is guaranteed, agricultural products are brought into the market in advance, and the economic value is increased;
4. the white mulching film can play a role in photosynthesis by sunlight penetrating, and is beneficial to growth of weeds on the ground; the grass-proof ground fabric provided by the invention has good shading performance, the dark color or black grass-proof ground fabric can prevent sunlight from directly irradiating the ground, and meanwhile, the firm structure of the ground fabric is utilized to prevent weeds from penetrating through the ground fabric, so that the inhibition effect of the ground fabric on the growth of the weeds is ensured;
5. the mulching film cannot play a role in draining water because no gap exists; the grass-proof ground cloth provided by the invention has good water permeability and air permeability. The grass-proof cloth can drain accumulated water on the ground in time and keep the ground clean. The drainage performance of the ground cloth ensures that the surface accumulated water is quickly drained, the soil and the fertilizer efficiency are not lost, and the cleanness of the surface of the ground cloth is ensured. In addition, the growth of the roots of the plants is facilitated, and the roots are prevented from rotting; the use of the meadow cloth, especially in arid areas, keeps the water content of the soil below, has small evaporation and saves the cost of irrigation and water;
6. the grassland cloth provided by the invention is beneficial to cultivation management, unidirectional or bidirectional marking lines are woven on most of the ground cloth according to requirements, and when flowerpots are placed in a greenhouse or outdoors or cultivation substrates are arranged, the arrangement can be accurately carried out according to the marking lines; in addition, the grass-proof cloth material provided by the invention has light weight and good flexibility, and is convenient to ship, lay and construct.
