specific Embodiment approach

[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, when the photobiodegradable environmental protection agricultural film (1) provided by the present invention is shattered by the action of the photosensitizer (3) under sunlight (6), and after being in contact with moisture (7) for an appropriate time, the average After the natto bacteria powder (4) distributed in the polyethylene (2) plastic raw material is activated and released, a large number of pores (8) are formed, and the ore powder (5) disintegrates accordingly, and loses the original space between it and the plastic raw material polyethylene. The phenomenon of biodegradation occurs due to the molecular connection of the molecules, and then achieves the purpose of rapid decomposition of the discarded SEP environmental protection agricultural mulch film after use.

Embodiment 1

[0019] Melt 820g of polyethylene, 10g of cerium stearate, 3g of natto powder, 130g of calcite powder, and 30g of polyethylene wax, stir and mix evenly, and finally form a film.

Embodiment 2

[0021] Melt 820g of polypropylene, 10g of zinc stearate, 3g of natto bacteria powder, 130g of marble powder and talcum powder, and 30g of paraffin wax, stir and mix evenly, and finally form a film.

Abstract

The invention discloses a light-biological double-degradation agricultural film, which comprises the following ingredients in percentage by weight: 81%-86% of plastic materials, 1%-3% of photosensitizer, 0.1%-0.3% of natto bacillus powder, 11%-13% of ore powder and 1%-3% of additive. The light-biological double-degradation agricultural film has the beneficial effects that: the photosensitizer, the natto bacillus powder and the ore powder are added in a polyethylene raw material for producing the agricultural film, so that the chemical structure of the agricultural film on an agricultural land can be changed (molecular weight is decreased) due to the action of natural daylight on the photosensitizer, the material strength is lowered, the phenomena of breakage and crushing occur, and the agricultural film can be quickly and effectively degraded in soil naturally after the natto bacillus powder and the ore powder are in contact with moisture in the soil.

Description

technical field [0001] The invention relates to an environment-friendly agricultural mulch film, more precisely, relates to a photo-biological double-degradation environment-friendly agricultural mulch film. Background technique [0002] Agricultural mulch film has the effects of moisturizing, heat preservation, weed prevention, and increasing production when used on crops. It has been widely used by farmers on agricultural land. [0003] The traditional agricultural mulch film is a film made of high-molecular polyethylene material blown. This film is not easy to decompose, and has the so-called "permanent for a hundred years, white pollution" and other shortcomings. [0004] The use of agricultural plastic film, if not recycled, will be mixed into the agricultural land during the cultivation period. Because of its characteristics such as not easy to decompose, the soil contains a large amount of accumulated plastic film over the years, which hinders the flow of water in the...
