Embodiment 1

[0019] A kind of transparent silver and black three-color multifunctional composite plastic film, see figure 1 , the composite mulching film includes transparent film bodies 1 on the left and right sides, and the silver film body 2 on the top and the black film body 3 on the bottom are connected between the transparent film bodies 1 on the left and right sides, see figure 2 , the right side of the transparent film body 1 on the left and the left side of the transparent film body 1 on the right are respectively crossed between the silver film body 2 and the black film body 3 through thermoplastic extrusion molding to form an integrated composite structure; the transparent film A protective tape 4 is connected between the body 1 and the silver film body 2 and the black film body 3 .

[0020] In the transparent silver-black three-color multi-functional composite mulch film of this embodiment, crops are planted in 1 place of its transparent film body, which absorbs sunlight durin...

Embodiment 2

[0026] A kind of transparent silver and black three-color multifunctional composite plastic film, see image 3 , Similar to Example 1, the difference is that there are two silver film bodies 2 and two black film bodies 3 respectively, and two silver film bodies 2 and black film bodies 3 are distributed side by side in the left and right directions.

[0027] In this way, the number and coverage area of ​​the transparent film body 1 between the silver film body 2 and the black film body 3 can be increased, which is suitable for the planting needs of larger crops.

Embodiment 3

[0029] A kind of transparent silver-black three-color multifunctional composite mulching film, similar to embodiment 1, the difference is, see Figure 4 , the left side and the right side of the composite plastic film are provided with at least two pairs of tear openings 5 ​​at intervals, and the composite plastic film between each pair of tear openings 5 ​​is provided with a tear line 6 . In this way, during use, the composite plastic film of required length can be intercepted according to needs, and when intercepted, it is torn through the tear opening 5, so that the composite plastic film is torn through the tearing line 6 to cut off the composite plastic film. to the desired length.

[0030] It should be noted that the tearing line 5 here may be at least two through holes arranged at intervals. The through holes may be strip holes. The strip-shaped holes may be rectangular holes. The sides of the two ends of the rectangular hole in the length direction may be arc-shape...

Abstract

The invention belongs to the technical field of mulching films, and discloses a transparent silver-black three-color multifunctional composite mulching film and a manufacturing method thereof. The composite mulching film comprises a left transparent film body and a right transparent film body, an upper silver film body and a lower black film body are connected between the left transparent film body and the right transparent film body, the right side of the left transparent film body and the left side of the right transparent film body are intersected between the silver film body and the blackfilm body in a thermoplastic extruding and forming manner to form an integrated composite structure. Protective belts are connected among the transparent film bodies, the silver film body and the black film body, the mulching film has weeding and disease-insect-resistant functions and is good in light transmittance performance and reflective performance, illumination and heat preservation effectsare improved, and root development and germination growth of crops are facilitated.

Description

technical field [0001] The invention belongs to the field of plastic film technology, and in particular relates to a transparent silver-black three-color multifunctional composite plastic film and a manufacturing method thereof. Background technique [0002] At present, in the field of agricultural planting, transparent mulch structures are mostly used, and most of them have the problems of no weeding function and poor lighting effects. The structure of black mulch or silver black mulch is also used in the prior art, but black mulch or silver black mulch often has problems such as opacity, low ground temperature in winter greenhouses, no germination of on-demand seeds, and slow root development. In addition, there is also a black and white mulch structure in the prior art, but the black mulch has poor reflective performance and does not have the function of resisting diseases and insect pests. Contents of the invention [0003] Aiming at the problems existing in the prior...
