Embodiment 1

[0029] This embodiment provides a PE anti-grass cloth with long-term anti-aging function. Calculated by mass percentage, the raw material composition of the PE anti-grass cloth is:

[0030] 85% polyethylene, 5% color masterbatch, 5% anti-aging additives, 5% filler masterbatch.

[0031] The raw material composition of color masterbatch is: polyethylene 15%, polyethylene wax 25%, carbon black 30%, calcium carbonate 30%.

[0032] The raw material composition of the anti-aging auxiliary agent is: 77.5% of polyethylene, 20% of light stabilizer, 2% of antioxidant, and 0.5% of lubricant. The light stabilizer is LS770; the antioxidant is a mixture of antioxidant 1010 and antioxidant CA in a mass ratio of 1:1; the lubricant is glyceryl stearate.

[0033] The raw material composition of the filler masterbatch is: calcium carbonate 82%, coupling agent 1%, dispersant 1%, lubricant 4%, polyethylene 12%. The coupling agent is KH560; the dispersant is ethylene-acrylic acid copolymer; the l...

Embodiment 2

[0035] This embodiment provides a PE anti-grass cloth with long-term anti-aging function. Calculated by mass percentage, the raw material composition of the PE anti-grass cloth is:

[0036] 90% polyethylene, 4% color masterbatch, 3% anti-aging additives, 3% filler masterbatch.

[0037] The raw material composition of color masterbatch is: polyethylene 15%, polyethylene wax 25%, carbon black 30%, calcium carbonate 30%.

[0038] The raw material composition of the anti-aging auxiliary agent is: 77.5% of polyethylene, 20% of light stabilizer, 2% of antioxidant, and 0.5% of lubricant. The light stabilizer uses N539; the antioxidant uses antioxidant TNP; the lubricant uses polyethylene wax.

[0039] The raw material composition of the filler masterbatch is: calcium carbonate 82%, coupling agent 1%, dispersant 1%, lubricant 4%, polyethylene 12%. The coupling agent is a mixture of SCA1503 and KH560 at a mass ratio of 1:1; the dispersant is ethylene-acrylic acid copolymer; the lubri...

Embodiment 3

[0041] This embodiment provides a PE anti-grass cloth with long-term anti-aging function. Calculated by mass percentage, the raw material composition of the PE anti-grass cloth is:

[0042] 87% polyethylene, 5% color masterbatch, 4% anti-aging additives, 4% filler masterbatch.

[0043] The raw material composition of color masterbatch is: polyethylene 15%, polyethylene wax 25%, carbon black 30%, calcium carbonate 30%.

[0044] The raw material composition of the anti-aging auxiliary agent is: 77.5% of polyethylene, 20% of light stabilizer, 2% of antioxidant, and 0.5% of lubricant. The light stabilizer is a mixture of LS770 and N539 in a mass ratio of 2:1; the antioxidant is a mixture of antioxidant 1010, antioxidant CA and antioxidant TNP in equal parts by mass; the lubricant is glyceryl stearate and Polyethylene wax is a 1:1 mixture by mass.

[0045] The raw material composition of the filler masterbatch is: calcium carbonate 82%, coupling agent 1%, dispersant 1%, lubricant...

Abstract

The invention discloses PE grass-resistance ground cloth with a long-lasting anti-aging function. The ground cloth is prepared from, by mass, 85-90% of polyethylene, 4-5% of color master batch, 3-5% of an anti-aging auxiliary agent and 3-5% of filling master batch. By optimizing and improving the formula design, the anti-aging performance of the grass-resistance ground cloth is greatly improved, the ground cloth can be used for 5-10 years and has the advantage that one-time investment to the ground cloth can achieve using for many years, the mechanical performance is good, and in addition, theground cloth has good shading, ventilating, water seepage and heat-preservation properties.

Description

technical field [0001] The invention relates to the technical fields of agriculture and gardening, in particular to a PE anti-grass cloth with long-acting anti-aging function. Background technique [0002] In the current agricultural planting of crops, weeds are easy to grow in the gap area outside the planted crops and the distance between fruit trees, which affects the attraction and growth of crop fertilizer efficiency. Green planting is now advocated, and manual weeding is required at least four times a year, which increases labor costs. input. [0003] However, the use of the existing agricultural mulch film has poor sunshade effect, impermeability, and airtightness, which affects soil respiration and prevents the ground from going up and down, which may cause plant roots to rot and affect yields; Human body, crops, soil, etc. are all harmed and affected. Agricultural membranes have a short service life, generally within one year, and a large amount of manual cleaning...
