Abstract
The utility model relates to the technical field of laminate products, in particular to a waterproof reticulate TPU composite film which covers a plastic greenhouse. The utility model adopts the technical scheme that the waterproof reticulate TPU composite film comprises a TPU composite film base layer, wherein the TPU composite film base layer is covered by a nylon net layer; the nylon net layer is coated with a hot melt adhesive layer; a nylon fabric layer is connected with the hot melt adhesive layer in a fusion manner. Compared with the prior art, the waterproof reticulate TPU composite film has the advantages that the tensile strength and bearing capacity can be ensured, and the service life is long.
Description
Technical field
The utility model relates to laminar product technical field, relates in particular to a kind of netted TPU composite membrane of waterproof covering on hot house.
Background technology
Traditional cover the canopy film on hot house, conventionally (for example adopt the plastic, transparent film of single layer structure, TPU film), in the time of the atrocious weather such as meet heavy rain or snow heavily, not only water resistance cannot ensure, and due to this plastic, transparent film strength and stretching resistance all lower, under the impact of heavy rain or heavy snow, be easy to make canopy film to be destroyed.
For solving the problems of the technologies described above, China Patent No. is to disclose < < waterproof net shaped composite film > > in 201220176364.1 patent documentation, and its primary structure is for comprising TPU film and wire netting compartment; Described wire netting compartment is covered in the upper surface of TPU film, and forms a net shaped composite film structure with described TPU film.By increasing wire netting, when realizing the tensile strength that improves waterproof net shaped composite film, increased the bearing capacity of waterproof net shaped composite film; Owing to adopting wire netting, the rigidity of wire netting is larger, and pliability is poor, repeatedly after bending, wire netting easily and TPU divided thin film from, and wire netting easily fractures after repeatedly bending; And after long-term use, getting rusty easily appears in wire netting, after wire netting surface oxidisation, form powdered oxide, make iron wire Netease and TPU divided thin film from, there is the short defect in service life of composite membrane.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of both can guarantee tensile strength and bearing capacity, and the netted TPU composite membrane of the waterproof of long service life.
For achieving the above object, the utility model provides following technical scheme: the netted TPU composite membrane of a kind of waterproof, include TPU film basic unit, it is characterized in that: in described TPU film basic unit, be coated with nylon stratum reticulare, described nylon stratum reticulare is coated with hot melt adhesive layer, and on described hot melt adhesive layer, welding has nylon layer of cloth.
By adopting technique scheme, nylon stratum reticulare plays booster action, guarantees tensile strength and the bearing capacity of the netted TPU composite membrane of waterproof, and nylon wire and wire netting ratio, have better pliability, simultaneously repeatedly bending is not fragile, improves the netted TPU composite membrane of waterproof service life; And nylon wire is plastic material, through hot melt adhesive layer YuTPU film, basic unit forms good composite joint; The nylon layer of cloth of welding on hot melt adhesive layer, avoids rainwater directly to contact nylon stratum reticulare with sunlight, plays protective action.
The utility model is further set to: in described TPU film basic unit, be coated with 2 layers or 3 layers of nylon stratum reticulare, the mesh between described each nylon stratum reticulare is dislocatedly distributed.
By adopting technique scheme, adopt 2 to 3 layers of nylon stratum reticulare design, play booster action, further improve the booster action of nylon stratum reticulare to the netted TPU composite membrane of whole waterproof, guarantee tensile strength and the bearing capacity of the netted TPU composite membrane of waterproof; And this number of plies design, avoids nylon wire layer thickness excessive, causes the poor problem of the netted TPU composite membrane of whole waterproof pliability.
The utility model is further set to: described TPU thin film based layer thickness is 0.3 ~ 0.5mm.
Described nylon cloth layer thickness is 0.1 ~ 0.3mm.
By adopting technique scheme, TPU film basic unit selects thickness moderate, avoids thin, insufficient strength, blocked up waste material.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the netted TPU composite membrane of the utility model waterproof explosive view;
Fig. 2 is Figure 1A part partial enlarged view.
The specific embodiment
Referring to accompanying drawing 1 and accompanying drawing 2, the netted TPU composite membrane of the disclosed a kind of waterproof of the utility model, includes TPU film basic unit 1, in described TPU film basic unit 1, is coated with nylon stratum reticulare 2, described nylon stratum reticulare 2 is coated with hot melt adhesive layer 3, and on described hot melt adhesive layer 3, welding has nylon layer of cloth 4.Nylon stratum reticulare 2 plays booster action, guarantees tensile strength and the bearing capacity of the netted TPU composite membrane of waterproof, and nylon wire and wire netting ratio, has better pliability, and repeatedly bending is not fragile simultaneously, improves the netted TPU composite membrane of waterproof service life; And nylon wire is plastic material, through hot melt adhesive layer 3, realizes YuTPU film basic unit 1 and form good composite joint; The nylon layer of cloth 4 of welding on hot melt adhesive layer 3, avoids rainwater directly to contact nylon stratum reticulare 2 with sunlight, plays protective action.
In this specific embodiment, in described TPU film basic unit 1, being coated with in 2 layers or 3 layers of nylon stratum reticulare 2(figure is 2 layers), the mesh between described each nylon stratum reticulare 2 is dislocatedly distributed.Adopt 2 to 3 layers of nylon stratum reticulare design, play booster action, further improve the booster action of 2 pairs of netted TPU composite membranes of whole waterproof of nylon stratum reticulare, guarantee tensile strength and the bearing capacity of the netted TPU composite membrane of waterproof; And this number of plies design, avoids nylon wire layer thickness excessive, causes the poor problem of the netted TPU composite membrane of whole waterproof pliability.
For further improving the protective action of nylon layer of cloth 2, described nylon layer of cloth outer surface is coated with waterproof coating 5, and waterproof coating 5 can be polyvinyl chloride resin, synthetic rubber or nano water-proof oil-proofing agent.
The netted TPU composite membrane of waterproof of the present utility model is preferred, and described TPU film basic unit 1 thickness is 0.3 ~ 0.5mm.Described nylon layer of cloth 2 thickness are 0.1 ~ 0.3mm.TPU film basic unit 1 selects thickness moderate, avoids thin, insufficient strength, blocked up waste material.。
