Description
Technical field
The present invention relates to agricultural film production technical field, and in particular to a kind of new Grass Silage Films.
Background technology
Grass silage is the fermentation using microorganism, long-term one kind for preserving green forage nutrition it is simple, economical and
Reliable method, is the effective measures for ensureing domestic animal stable market supply roughage all the year round.China is in the Yuan Dynasty《Wang Zhennong books》Deng in book
Just there is the record of alfalfa ensilage fermentation process, ensiling turns into an important technology in animal husbandry now.
Grass silage has many good qualities：It can not only be preserved with the mode of modulation hay, it is also possible to which the mode of ensiling is carried out
Storage；The loss of nutriment can be reduced, if silage facilities are advanced, technical operation is suitable, and the loss of nutrition is usually no more than
15%, and keep in green grass more than 90% carrotene；Ensilage can improve the palatability and digestibility of domestic animal, through micro- life
Ensiling herbage after thing fermentation has sour fragrance, and soft and succulency, palatability is good, can stimulate the appetite of domestic animal, lactic acid is to intestines in addition
The stimulation of stomach significantly improves digestibility, and ensiling can make herbage be maintained at blue or green fresh state for a long time, rich in protein, Duo Zhongwei
Raw element and mineral matter, can provide the feed of high nutritive value for domestic animal all the year round；The limit of the manufacturing process of ensiling not climate condition
System, overcast and rainy season or bad weather, it is difficult to when modulating hay, make ensiling influence smaller.
The key of grass silage process is to maintain anaerobic environment, and if air penetrates into, saccharomycete and mould will breed,
The not only sugar and lactic acid in consumption ensiling herbage, and decomposition of cellulose and other cell wall constituents, produces harmful metabolism
Material, causes temperature and pH value to rise, makes the dry and nutrient of ensiling herbage all by very big loss.The light transmittance of membrane material
Also the effect of grass silage is influenceed, transmitted light can promote the loss of some nutriments, herbage is used as with transparent plastic sheeting
Ensiling film is failure.Therefore, the plastic sheeting for grass silage plays very important effect to the effect of grass silage.
But, the grass silage film sold in the market has that tensile strength is not high, paracentesis resistance is poor, thickness and uneven thickness,
Tack is bad, the shortcomings of causing that broken rate is very high, sealing is poor, light transmittance is strong, effectively can not keep anaerobic environment.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of tensile strength is high, paracentesis resistance and good seal performance
Grass silage dedicated film.
To realize object above, the present invention is achieved by the following technical programs：
A kind of new Grass Silage Films, the film is made up of intermediate layer and first, second top layer；The intermediate layer is by quality
Fraction is 76-85% linear metallocene low density polyethylene (LDPE), 12-21% modified thickening masterbatch, 3-5% anti-aging mother material
Composition；First, second top layer is by 66-75% linear metallocene low density polyethylene (LDPE), 8-12% rutile-type increasing
White shading masterbatch, 5-12% anti-aging mother material, 2-5% weather-proof masterbatch, 2-5% ultraviolet-resistance masterbatch composition.
Further, the intermediate layer is by linear metallocene low density polyethylene (LDPE), 15- of the mass fraction for 78-82%
18% modified thickening masterbatch, 3-4% anti-aging mother material composition；First, second top layer by 69-73% linear cyclopentadienyl
Metal low density polyethylene (LDPE), 9-11% rutile-type brightens shading masterbatch, and 6-10% anti-aging mother material, 3-5%'s is weather-proof
Masterbatch, 3-5% ultraviolet-resistance masterbatch composition.
Further, the intermediate layer by mass fraction for 80.5% linear metallocene low density polyethylene (LDPE), 15.7%
Modified thickening masterbatch, 3.8% anti-aging mother material composition；First, second top layer by 72.3% linear metallocene
Low density polyethylene (LDPE), 9.5% rutile-type brightens shading masterbatch, 8.4% anti-aging mother material, 4.9% weather-proof masterbatch,
4.9% ultraviolet-resistance masterbatch composition.
Further, the film is arranged in order composition by the first top layer, intermediate layer and the second top layer；The film is by the first table
The thickness ratio on layer, intermediate layer and the second top layer is 1-2：1-3：1-2.
Further, the film is arranged in order composition by the first top layer, intermediate layer and the second top layer；The film is by the first table
The thickness ratio on layer, intermediate layer and the second top layer is 1：2：1.
Further, the thickness of the film is 0.023-0.028mm.
Beneficial effects of the present invention are：
1. the Grass Silage Films surfaces externally and internally toughness that the present invention is provided, packs airtight, waterproof, inside can be formed
Anaerobic environment, can contribute to animal digestion, improves dairy fat content by the controlled anaerobic fermentation of ensiling into the feed of high nutrition,
Highest can per day milk-increasing quantity 5-7kg/ heads.
2. the Grass Silage Films tensile strength that the present invention is provided is high, elongation is big, and paracentesis resistance is strong, it is ensured that grass silage
It is not damaged in journey, feed qualitative change is prevented effectively from, goes mouldy or nutriment is lost in and causes economic loss.
3. the grass silage thickness that the present invention is provided is uniform, light transmittance is low, it is to avoid heat accumulation；PH value temperature, service life
It is long, it can be exposed to greatest extent in ultraviolet 3 years.
