Description

A kind of agricultural film

Technical field

The utility model relates to the film field, relates in particular to a kind of agricultural film.

Background technology

Agricultural film is the general name that is applied to the plastic film of agricultural production, and along with scientific and technical progress, more and more higher to the requirement of agricultural film, existing agricultural film is generally single layer structure, and its shortcoming is as follows: 1, product structure is single, poor performance; 2, the whole poor mechanical property of product, be embodied on the tensile strength and tearing strength of film; 3, as with new and old raw material, mixed and use or use regenerative raw materials, the outer surface poor-performing, be mainly reflected in the brightness and transparency of film; 4, do function film product cost high.

Existing agricultural film in use, such as at booth, building as overlay film and use, perhaps directly as mulch film, use, all need to be fixed by the edge to agricultural film, its fixed structure complexity, the time of fixing cost is longer, and, also easily be fixed in the fixation procedure sharp parts of structure of the edge of existing agricultural film is made a mess of, and the agricultural film of damage can not be reused, and has caused very large waste.

The utility model content

The utility model proposes a kind of agricultural film, it can overcome deficiency of the prior art effectively, its structural strength is good, the less investment of equipment, reduced production cost in process of production, can effectively improve output, improve the economic benefit of enterprise, and the utility model is installed simple and convenient, not fragile, long service life.

The technical solution of the utility model is achieved in that a kind of agricultural film, by base layer, lay respectively at two performance layer of base layer both sides, lay respectively at the film body of the functional layer composition in two performance layer outsides, the thickness of described film body is 0.02～0.6mm, the thickness of described base layer accounts for 40%～60% of film body thickness, the thickness in monolayer of described performance layer accounts for 18%～28% of film body thickness, and the edge, two vertically long limits of described film body is equipped with the tubular structure identical with film body length.

As preferably, the thickness of described base layer accounts for 50% of film body thickness, and the thickness in monolayer of described performance layer accounts for 23% of film body thickness, and the thickness in monolayer of described functional layer accounts for 2% of film body thickness.

As preferably, described performance layer is the thermal insulation separation thermosphere.

As preferably, described functional layer is anticorrosive coat.

As preferably, described functional layer is antirust coat.

As preferably, described functional layer is anti-aging layer.

As preferably, described functional layer is anti-drip layer.

The beneficial effects of the utility model are: the utility model is five laminar composite membranes, can adopt different functional layers according to the difference of its purposes, and its effect has solved the deficiency that the single thin film technology is brought, and can improve performance, reduces production costs.It is mainly implemented by the following technical programs: adopt different functional layers, make film body meet the different functional requirements of using, can reach respectively the Functional Requirements such as anticorrosion, antirust, anti-aging, anti-drip; Base layer and performance layer can effectively be improved the mechanical property of product, and the simultaneity ergosphere can play insulation, the effect such as heat insulation; And the edge, two vertically long limits at film body is provided with tubular structure, can penetrate the fixtures such as rope, in overlay film and folding and unfolding process, the effectively low labour intensity that reduced, be very easy to actual use, improved operating efficiency, and this tubular structure also can increase the overall construction intensity of film body, make film body not fragile, thereby increase the service life of film body.The utility model has adopted two main frames (A main frame, B main frame) ABA pattern head technology, has realized that the A layer is extexine (the being functional layer) brightness that meets film surface, fineness, ageing-resistant, weeding, anti-drip, the Functional Requirement such as antirust; The B layer is internal layer (being base layer and two performance layer), at the B main frame, add reinforcing material to meet the mechanical property requirements such as tensile strength, tearing strength, elongation at break of film, under the prerequisite that meets film outer surface quality and basic mechanical performance, the B layer also can add low-cost raw material, reduces production costs.
