At present, the common reflective film for the sea is fixedly arranged on the maritime clothes in a self-adhesion or sewing mode. Due to environmental factors of use, for example, marine garments are wetsuits. Wetsuits are used while submerged. When the reflective membrane fixed on the diving suit adopts a sewing mode, water enters the diving suit due to a pinhole generated by sewing, and the use is influenced. When the reflective membrane adopts the self-adhesion to connect, drop easily when using, lead to unable reflection of light warning.
The utility model content is as follows:
the utility model aims to provide a maritime affairs reflective film which is firmly connected with maritime affairs clothes and can not enter water when in use.
The utility model is realized by the following steps:
the utility model provides a maritime affairs reflective membrane, includes by the lower supreme hot melt adhesive layer that sets gradually, be used for the first PU layer of support, be used for connecting second PU layer, glass bead layer and the modified PVC surface course on glass bead layer, glass bead layer is laid on second PU layer by glass bead, glass bead's lower part inlays and establishes in second PU layer, the modified PVC surface course sets up in the top on glass bead layer, is formed with the gasbag between the bottom surface of adjacent glass bead and modified PVC surface course, is provided with the layer of aluminizing in glass bead's lower part.
In the maritime affair reflective membrane, the refractive index of the glass beads is 1.9-1.95.
In the above marine reflection film, the diameter of the glass beads is 30 μm to 100 μm.
In the maritime affairs reflective membrane, the thickness of the hot stamping layer is 38-42 μm.
In the above marine reflective film, the first PU layer has a thickness of 28 to 32 μm.
In the above marine reflective film, the second PU layer has a thickness of 23 to 27 μm.
In the maritime affairs reflective membrane, the thickness of the modified PVC surface layer is 70-170 μm.
Compared with the prior art, the utility model has the outstanding advantages that:
1. the utility model adopts the hot melt adhesive as the base material, and the hot melt adhesive is connected with the surface of the marine clothing in a hot ironing way, so that the connection is firm, the service life is long, the reflective warning effect is good, the condition that the marine clothing is watered due to the needle eye caused by adopting a sewing type fixing way in the prior art is avoided, and the condition that the marine clothing is not firmly connected with the marine clothing and falls off caused by adopting a self-adhesive fixing way in the prior art is also avoided;
2. the utility model is an air bag type reflective membrane, an air bag is arranged between a modified PVC surface layer and a glass bead layer, the elasticity of the product can be improved, and users do not feel foreign matters;
3. the utility model is provided with two PU layers, the second PU layer firmly adheres the glass beads, and the first PU layer plays a supporting role, so that the glass beads can not sink into the first PU layer to lose the light reflection effect in a low-latitude sea area under the condition that the environmental temperature rises to 60-70 ℃ or even 80 ℃, and the vitrification temperature of a glue layer is increased.
