Description
Technical field
The present invention relates to a kind of novel slim Agricultrual Polyolefin Greenhouse Films and the preparation method with function synergy, belong to agricultural functional thin film technique field.
Background technology
China is large agricultural country, has cultivated area per capita and only has 1.4 mu, have 40% of cultivated area less than the world per capita, and arable land and the realistic pressure of population determine agriculture must the kind on limited soil of China and raise more farm crop.And the growth conditions that the growth needs of farm crop is suitable, photo-thermal reaction can be described as of paramount importance external ecology condition in plant growing process.The development of domestic agricultural planting nearly decades forms the artificial light temperature environmental system based on agricultural plastic film gradually.Therefore, development industrialized agriculture is particularly important, and industrialized agriculture key problem is the utilization of sunlight, and key is covering material.The state of the art of Agro-film Industry is mainly reflected in the functional plastic sheeting for farm use of high quality and high added value, is especially applied to the canopy film of heliogreenhouse.The daylight film for greenhouse overwhelming majority of current China is for having the film of drip, fog dispersal, high printing opacity, insulation.These functions also realize mainly through the interpolation of functional aid.But current most of canopy film causes its effect just to lose efficacy at short notice due to the fast transferring of functional aid, and therefore market in urgent need a kind of life-span is long, and the longevity imitates synchronous agricultural film material.
Summary of the invention
The object of this invention is to provide a kind of anti-droplet, there is the polyolefin long-acting trickle plastic sheeting for farm use of slow-release function and preparation method.
Anti-droplet, have the polyolefin long-acting trickle plastic sheeting for farm use of slow-release function, it is characterized in that, raw material used mainly comprises: polyolefine, the auxiliary agent with slow releasing function, photostabilizer, drip agent.
Preparation method be by polyolefin resin, have slow releasing function auxiliary agent, comprise photostabilizer mix with the functional master batch of drip agent after together with join in inflation film manufacturing machine, blown film temperature 130-240 DEG C, blowing obtains functionalized polyolefin long-acting plastic sheeting for farm use.
The present invention relates to one or more that polyolefin resin is selected from polyethylene, ethene-butene-1 copolymer, ethene-1-hexene copolymer, ethylene-l-octane copolymer, ethylene-vinyl acetate copolymer (VA content is greater than 4%).Wherein polyolefine preferred mass consumption 70-90%.
The present invention relates to the auxiliary agent with slow releasing function is containing the polyolefine (the preferred 5%-40% of percentage of grafting) of glycidyl methacrylate (GMA) grafting or the polyolefine (percentage of grafting 5%-40%) of maleic anhydride (MAH) grafting.The auxiliary agent preferably with slow releasing function accounts for the 0.5-5% of gross weight, and more preferably 2%.
The present invention relates to photostabilizer is hindered amines and/or metallo-chelate, preferable amount 0.3%-2%.
The present invention relates to drip agent that drip agent is ester class and amine compound or sorbyl alcohol acid esters is the composite drip agent of main body.Preferable amount 1%-3%.
The preparation method of a kind of functionalized polyolefin long-acting plastic sheeting for farm use provided by the invention.By adding the auxiliary agent that can play slow releasing function in plastic sheeting for farm use formula, appropriate change polyolefine forms the aggregated structure after goods, increase the quantity of tiny crystalline region, make the auxiliary agents such as drip agent can move to plastic sheeting for farm use surface slowly, thus guarantee the content keeping auxiliary agent in plastic sheeting for farm use surface within a certain period of time, make it to reach long-acting effect.
A kind of functionalized polyolefin long-acting plastic sheeting for farm use advantage of the present invention is: the functional agent with slow releasing function joins in plastic sheeting for farm use formula by (1), overcome the shortcoming of the PF losses such as conven-tional adjuvants fast transferring, precipitation, therefore make plastic sheeting for farm use have long-lasting nature; (2) the long-acting anti-dropping plastic sheeting for farm use prepared has long anti-fogging time, and under accelerating drip experiment condition at 60 DEG C, the anti-fogging time of long-acting anti-dropping plastic sheeting for farm use is 12-19 days; Under equal conditions, the anti-fogging time of commercial anti-dropping film is 6-8 days; Carried out by the commodity anti-dropping film of long-acting anti-dropping plastic sheeting for farm use and stack pile outdoorly buckleing canopy, the anti-fogging time of functionalized polyolefin long-acting plastic sheeting for farm use is 6-9 month; The anti-fogging time of commercial anti-dropping film is 3-4 month.
