specific Embodiment approach

[0029] combine figure 1 A specific embodiment of the present invention is shown: a two-color agricultural ground covering film, including two white plastic films 102 and a black plastic film 101, the black plastic film 101 is arranged between the two white plastic films 102, and is in phase with the two white plastic films 102 connect.

[0030] In this embodiment, the raw material components of the black mulching film 101, in parts by weight, include 20 parts of degradable masterbatch, 40 parts of linear low-density polyethylene, 5 parts of black masterbatch, and 1 part of melting agent; The raw material components of the white mulching film 102, in parts by weight, include 20 parts of degradable masterbatch, 40 parts of linear low-density polyethylene, 1 part of melting agent, 0.5 part of light stabilizer, 1 part of calcium carbonate masterbatch, The raw material components of the degradable master batch include 30 parts of corn starch, 10 parts of plant fiber, 10 parts of l...

Embodiment 2

[0037] combine figure 1 , the rest are the same as in Example 1, except that in this example, the raw material components of the degradable masterbatch, in parts by weight, include 30 parts of polylactic acid, 10 parts of plant fiber, linear low density poly 10 parts of ethylene, 5 parts of carbon dioxide polymer, and 1 part of plasticizer.

Embodiment 3

[0039] combine figure 1 , the rest are the same as in Example 1, except that in this example, the raw material components of the black mulching film 101, in parts by weight, include 5 parts of anti-aging masterbatch and 90 parts of linear low density polyethylene , 5 parts of black masterbatch; The raw material components of described white mulching film 102, in parts by weight, include 5 parts of anti-aging masterbatch, 85 parts of linear low density polyethylene, 7 parts of low density polyethylene, melting agent 2 servings.

Abstract

The invention discloses a bicolor agricultural soil covering film and a preparation method thereof and relates to the field of an agricultural soil covering film, comprising at least one black mulch film and at least one white mulch film, the white mulch film is effective in increasing surface temperature so as to partially remove weeds, in case of a single-color mulch film, a color combination is changed by changes in an extrusion passage in a nose so that a color combination mode is changed, and existing single-color mulch film is finally imparted two colors and is suitable for various applications, and the film has temperature rising, humidity holding and good weeding effect, is very applicable to agriculture, and is simple to prepare, low in cost and higher in economic benefit.

Description

technical field [0001] The invention relates to the field of agricultural ground covering films, in particular to a two-color agricultural ground covering film and a preparation method thereof. Background technique [0002] At present, in agriculture, there are two commonly used mulch films, one is black mulch film and the other is white mulch film. Black mulch has a better moisturizing effect; but it makes the land warmer more slowly. Due to its poor light transmittance, the white plastic film has a good warming effect on the land after it is laid. More weeds. [0003] In the process of planting crops with mulch film, it is a new development trend to make the mulch film achieve a better effect of warming and moisturizing while also having a better weeding effect; however, in related technologies, whether it is black mulch or white Mulch film, none of which can increase temperature and moisturize and have a good weeding effect. [0004] In response to the above problems,...
