Description
Technical field
The invention belongs to agricultural wastes reprocessing technical field, specifically a kind of waste mulching film toughening modifying method.
Background technology
Plastic mulching cultivation technology have soil moisture conservation, heat, the effect such as weeding, insect protected and volume increase, be that developing modern agriculture increases
Produce the important means increased income, particularly more become in cold, non-irrigated farming region and protect the major measure that grain increases income.From late 1970s
Phase, China introduces plastic mulching cultivation technology, makes the yield of crops be greatly improved, and obtain significant economy
Benefit, is sung the praises of as " White Revolution " agriculturally by people.During large-scale application plastic mulching cultivation technology, due to ground
Film is difficult to natural degradation, causes widespread pollution from the overuse of fertilizers and pesticides in rural area to aggravate, and causes " visual pollution " and potential hazard.Remain in the ground in soil
If film is not removed, it can directly destroy soil original structure, reduces farmland quality, and the noxious substance of precipitation also can polluted underground water
Source；Also can affect the growth of crop root and be uniformly distributed, hindering crop to moisture and the absorption of nutrient, cause crop failure.
Additionally, mulch film reclaims, post processing is improper will also result in serious harm, such as can produce after processing in burning mode has poison in a large number
Body, causes secondary environmental pollution；If arbitrarily abandoning, natural landscape can be affected, also can affect environmental health, produce visual pollution,
Also can be mixed in straw, herbage, domestic animal can cause disease the most dead after eating by mistake.Therefore, waste mulching film recycling gesture exists
Inevitable, also it is one of environmental administration pays close attention to most instantly problem.
Worn-out agricultural film reclaims and regeneration processing and utilization has been made a lot of useful exploration and achieved good warp in various places
Testing, the regeneration of worn-out agricultural film processing has two ways at present: one be by reclaim the residual film that comes by dry in the sun, pulverize, rinse, get rid of
Dry, extrusion, pelletizing, be processed into the raw material of other plastics, because still remain the chemical characteristic of plastic raw materials and good
Integrated materials performance, can meet the technology requirements such as blown film, wire drawing, trombone slide, injection, extrusion profile, is used for processing various film, pipe etc.
Goods；Two is to pass through the technical finesses such as high-temperature catalytic cracking by reclaiming after the residual film come passes through dry in the sun, rinsing, therefrom obtains vapour
The available fuels such as oil, diesel oil.While " white pollution " problem of solution, it is achieved that the recycling of waste mulching film, have good
Economic benefit and social benefit.
Summary of the invention
It is an object of the invention to provide a kind of waste mulching film toughening modifying method, by the waste mulching film of recovery through toughening modifying
Pelletize after process, the plastic pellet obtained can direct plunge into production as the raw material of other highstrenghtpiston's tubing.
In order to achieve the above object, the present invention is by the following technical solutions.
A kind of waste mulching film toughening modifying method, comprises the following steps:
(1) waste mulching film pretreatment: sort out Dyeing polyethylene mulch film in the waste mulching film reclaimed, is carried out, breaks
Broken, desolventing technology, pelletize after drying, obtain the waste mulching film granule of particle diameter 1-1.5mm, standby；
The most material modified preparation: by weight, adds titanate esters in 100-200 mesh fly ash float 100-200 part
Coupling agent 1-7 part, epoxy resin 10-150 part, stir 75-90min, dry at 75-100 DEG C, obtains modified coal ash drift
