Problems solved by technology

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 better weed control effect

Embodiment 1

[0031] The mulching film of this embodiment comprises two black mulching films 102 and a white mulching film 101; the white mulching film 101 is arranged between the two black mulching films 102, and is connected with the two black mulching films 102; wherein, in the In the black mulching film 102, according to parts by weight, its raw material components include: 40 parts of degradable masterbatches, 25 parts of linear low-density polyethylene, and 25 parts of carbon black masterbatches; Counting, its raw material components include: 40 parts of degradable masterbatch, 54 parts of linear low density polyethylene.

Embodiment 2

[0033] The mulching film of this embodiment comprises two black mulching films 102 and a white mulching film 101; the white mulching film 101 is arranged between the two black mulching films 102, and is connected with the two black mulching films 102; wherein, in the In the black mulching film 102, according to parts by weight, its raw material components include: 44 parts of degradable masterbatches, 28 parts of linear low-density polyethylene, and 28 parts of carbon black masterbatches; Counting, its raw material components include: 44 parts of degradable masterbatch, 56 parts of linear low density polyethylene.

Embodiment 3

[0035] The mulching film of this embodiment comprises two black mulching films 102 and a white mulching film 101; the white mulching film 101 is arranged between the two black mulching films 102, and is connected with the two black mulching films 102; wherein, in the In the black mulch 102, according to parts by weight, its raw material components include: 46 parts of degradable masterbatches, 30 parts of linear low-density polyethylene, and 30 parts of carbon black masterbatches; in the white mulch 101, according to parts by weight Counting, its raw material components include: 46 parts of degradable masterbatch, 60 parts of linear low density polyethylene.

[0036] In all the above-mentioned embodiments, in order to make the mulch film have a better effect of warming and moisturizing; and to ensure its quality, its multi-functionality (including the performance of easy degradation) is more excellent. Preferably, in the degradable masterbatch; its raw material composition inc...

Abstract

The invention relates to the technical field of agriculture and specifically relates to a mulching film and a preparation method thereof. The mulching film comprises two black mulching films and a white mulching film which is arranged between the two black mulching films and connected with the two black mulching films, wherein the black mulching films are prepared from the following raw material components in parts by weight: 40-46 parts of degradation master batches, 25-30 parts of linear low-density polyethylene, 25-30 parts of carbon black master batches; the white mulching film is prepared from the following material components in parts by weight: 40-46 parts of degradation master batches and 54-60 parts of linear low-density polyethylene. The mulching film provided by the invention has warming and moisture-preserving effects and better wedding effect, can be applied to the agriculture very well, and is more beneficial to health of crops.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a mulch 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] To sum up, it is a technical problem to be solved urgently in this field to pr...
