Abstract
The utility model discloses a five layers away from type coating crowd nylon complex film altogether be, include a nylon layer who sets gradually, first bond line, polyethylene layer, second bond line, the 2nd nylon layer and leave the type layer, a nylon layer, first bond line, the polyethylene layer, the second bond line, five layers of coextrusion blow of the 2nd nylon layer nylon complex film that forms, spraying silicon oil layer on nylon layer surface is from the type layer, the bond line is formed according to the 2 proportion mixturees of 1: with the polyethylene from high pressure process by the bonding resin, the nature peeled off is good, high product quality, etc, moreover, the steam generator is simple in structure, nylon layer's existence, make its high temperature that can bear 120 DEG C - 150 DEG C, be applied to in the aspect of wind -powered electricity generation blade and the fan machinery room cover vacuum forming, resin contact from the type layer with the priming by vacuum, make its very easy and resin peel off behind the resin curing.
Description
Technical field
The utility model relates to a kind of coextrusion nylon film, specifically, relates to a kind of release coating five-layer co-squeezing coextrusion nylon film, belongs to nylon membrane production technical field.
Background technology
Vacuum assisted resin infusion (VARI) technique is a kind of low cost liquid molding technique of novel large-scale composite material product, and it mainly utilizes negative pressure of vacuum discharge the gas in fiber and realize the dipping of resin to fiber.This technique needs to lay coextrusion nylon film that is high temperature resistant, high-barrier and forms confined space, and lead note and pre-compacted by vacuum, hot setting obtains goods, and this technique is widely used in the making of the large-scale components such as yacht, blade, engine room cover.
Realizing in process of the present invention, inventor finds that prior art at least has the following disadvantages: prior art is when vacuum forming, coextrusion nylon film contacts with high-temperature resin, easily cause film and resin-bonded, after molding, need manually coextrusion nylon film to be separated with goods, both affected operating efficiency, and easily affected product apparent quality again.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of five-layer co-squeezing release coating films coextrusion nylon film, has the advantage that fissility is good, product quality is high.
For solving above technical problem, the utility model is by the following technical solutions: a kind of release coating five-layer co-squeezing coextrusion nylon film, is characterized in that: described coextrusion nylon film comprises the first nylon layer, the first adhesive layer, polyethylene layer, the second adhesive layer, the second nylon layer and the release layer that set gradually;
Described first nylon layer, the first adhesive layer, polyethylene layer, the second adhesive layer, the second nylon layer five-layer co-squeezing blowing form coextrusion nylon film.
A kind of prioritization scheme, described release layer is the silicon layer being sprayed on nylon layer surface.
Further, described first adhesive layer is by binder resin and the polyethylene from high pressure process adhesive layer that mixes of 1 ︰ 2 in mass ratio.
Further, stating the second adhesive layer described in is by binder resin and the polyethylene from high pressure process adhesive layer that mixes of 1 ︰ 2 in mass ratio.
After the utility model adopts above technical scheme, compared with prior art, have the following advantages: the resin contact of release layer and priming by vacuum, make it be easy to peel off with resin after resin solidification, product fissility is good, product quality is high; Confirmed by test: the high temperature that can bear 120 DEG C-150 DEG C, is applicable to being applied to wind electricity blade and blower fan cabin cover vacuum forming aspect.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of five-layer co-squeezing release coating films coextrusion nylon film in the utility model;
In figure,
1-first nylon layer, 2-first adhesive layer, 3-polyethylene layer, 4-second adhesive layer, 5-second nylon layer, 6-release layer.
Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.
Embodiment 1, as shown in Figure 1, a kind of release coating five-layer co-squeezing coextrusion nylon film, the first nylon layer 1, first adhesive layer 2 set gradually, polyethylene layer 3, second adhesive layer 4, second nylon layer 5 and release layer 6, first nylon layer 1, first adhesive layer 2, the blowing of polyethylene layer 3, second adhesive layer 4, second nylon layer 5 five-layer co-squeezing form coextrusion nylon film.
First adhesive layer 2 and the second adhesive layer 4 adhesive effects, for cost-saving, the first adhesive layer 2, second adhesive layer 4 is mixed in 1 ︰ 2 ratio by binder resin and polyethylene from high pressure process.Second nylon layer 5 surface spraying silicone oil of coextrusion blow composite membrane, forms release layer 6.
This release coating five-layer co-squeezing coextrusion nylon film structure is simple, the existence of nylon layer, makes it can bear the high temperature of 120 DEG C-150 DEG C, is applied to wind electricity blade and blower fan cabin cover vacuum forming aspect, release layer 6 and the resin contact of priming by vacuum, make it be easy to peel off with resin after resin solidification.
Above-mentioned detailed description of the invention is exemplary; to enable those skilled in the art better understand the utility model content; should not be understood as the restriction to the utility model protection domain; as long as according to the improvement that technical solutions of the utility model are done, all fall into protection domain of the present utility model.
Claims (2)
