The fireprotection layer thickness is 0.1-0.3mm.
The hypothallus cloth is the tatting, knitting, woven nitride layer of cotton, fiber crops, silk, terylene, polyamide fibre, acrylic or its blending Or nonwoven layer.
Complex metal plating layer is using conventional metallization film plating process, such as magnetron sputtering method or galvanoplastic in the present invention.
The beneficial effects of the invention are as follows：
1）Shield effectiveness is high.The present invention realizes product and existed by adjusting metal species and content and functional layer position Possess higher shield effectiveness in scope wider 10MHZ ~ 40GHz, its shield effectiveness can reach more than 80dB.
2）Functional.Compared with common metal coating cloth, cloth of the invention has by the optimum choice of coating Good pliability, electric conductivity, inoxidizability, heat-resisting quantity, antibiotic property and fire line, feature is extremely strong, be suitable for it is civilian, The multiple fields such as military, telecommunications and the particular surroundings such as explosion-proof.Its toughness is still preferable after multiple functions coating and use, This is due to that anti oxidation layer and fire prevention interlayer with the addition of appropriate Nano particles of silicon dioxide, and it is to due to complex metal plating layer Use and with obvious toughening effect the problem of the big hardness brought, maintain the pliability of matrix layer material, can Plasticity is extremely strong.In high temperature environments, sodium metasilicate and nano silicon in component coordinate fireprotection layer of the present invention with other components Use, the toughness of product can also be strengthened by having not only acted as the fire-retardant effect of synergistic, and fire protecting performance is good.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure, 1 is hypothallus, and 2 be complex metal plating layer, and 3 be high-temperature-resistant layer, and 4 be fireprotection layer, and 5 be anti oxidation layer.
Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of fire-type is electromagnetically shielded Antiradiation protection cloth, and it includes hypothallus, complex metal plating layer, resistance to height successively from top to bottom Warm layer, fireprotection layer and anti oxidation layer.
