Abstract
The invention discloses a kind of high intensity PVDF agricultural mulching, containing following mass percent component: PVDF resin 50%～80%, PMMA resin 10%～40%, inorganic pigment 0.05%～15%, light stabilizer 0.1%～3%, antioxidant 0.05%～0.1%, liquid paraffin 0.4%～0.5%；The present invention, by the blending and modifying that dissolves each other PVDF material, makes thin film have good flexibility and high intensity, adds the mobility in processing film-forming process and the Oil repellent of material, thus promotes the mechanical strength properties of thin film.
Description
Technical field
The present invention relates to a kind of agricultural mulching, specifically a kind of high intensity PVDF agricultural mulching.
Background technology
From China by plastic film applications in agricultural production so far, production practices have turned out: agripast is thin
The application of film mulching and planting technology, can not only promote plant growth, makes crop yield, increasing peasant income, and
Also change China's conventional agriculture.Wherein, plastic mulching cultivation technology, it can play insulation and protect
Root, antifreeze, soil moisture conservation, regulating illumination, water saving, weeding, insect protected and control the effect of soil salinity and alkalinity,
Early ripening of the crops can be promoted, improve crop yield and quality, moreover it is possible to realize the fruit and vegerable cultivation in cold season.
Along with the process of agricultural modernization, the usage amount of agricultural film gets more and more.As it has been described above, its advantage is
It will be evident that but its negative effect shows fork-like farm tool used in ancient China the most day by day.The most serious is just known as
" white pollution ", particularly remaining in agricultural film fragment in soil can gradually accumulate, formed barrier layer, seriously
Affect the normal growth of root system of plant, destroy Soil Thermal transmission and the dredging of moisture, ultimately cause the underproduction.I
Guo Shi large agricultural country, but in China's agricultural film city field boundary, mainly based on PE film, part is PVC film and EVA
Film, adds that the thinnest (Chinese Enterprises grown place film thickness is 6 μm, the U.S. for agricultural mulching that China uses
Being 24 μm, Korea S is 20 μm, and Japan is 15 μm) intensity is low, and weatherability, ageing resistace are poor, nothing
Opinion is in crop optimum period plastic film mulch, or in crop harvesting later stage winder, uses mechanical work rolling to reclaim and all hold
Easily make film rupture, affect machine and work continuously, it is difficult to play benefit.
Summary of the invention
It is an object of the invention to provide a kind of high intensity PVDF agricultural mulching, to realize the use year of agricultural mulching
Limit.
In order to reach above-mentioned technical purpose, the technical scheme is that
A kind of high intensity PVDF agricultural mulching, containing following mass percent component:
Described PVDF resin is the homopolymer of vinylidene fluoride.
Described PMMA resin is the homopolymer of methyl methacrylate, or alkyl acrylate, acrylonitrile,
At least one monomer and the copolymer of methyl methacrylate in butadiene, styrene co-monomer, or be first
Base acrylic acid methyl ester. homopolymer and the compositions of above-mentioned copolymer.
Described inorganic pigment is metal-oxide.
The present invention, by the blending and modifying that dissolves each other PVDF material, makes thin film have good flexibility and high-strength
Degree, adds the mobility in processing film-forming process and the Oil repellent of material, thus the machinery promoting thin film is strong
Degree performance.The interpolation of liquid paraffin increases electrical insulating property and flame resistance, can improve tensile strength.Thin film strong
Degree is remote surpasses other, and moisture-vapor transmission is less than 1.8g/m.d.
