Problems solved by technology

However, the coating on the surface of this type of protective cover is easy to fall off and fail after long-term use, thereby making its corresponding function invalid; at the same time, this type of protective cover usually has poor air permeability in order to have good waterproof performance, and water vapor is easy to Accumulates on the inner layer of the protective cover, thereby repelling moisture to the device

Abstract

The invention discloses a waterproof and flame-retardant composite fabric for an outdoor protection cover. The composite fabric comprises at least two flame-retardant fabric layers; a flame-retardantadhesive layer is clamped and bonded between the two adjacent flame-retardant fabric layers; a TPU microporous film layer is arranged on the surface of the flame-retardant fabric layer positioned on the outer side surface; the flame-retardant fabric layers are formed by interweaving pre-oxidized fibers and non-pre-oxidized fibers; the flame-retardant adhesive layer is prepared from a polyurethaneadhesive containing a halogen-free flame retardant and thermal expansion microspheres; and in addition, a plurality of micropores distributed at intervals are formed in the TPU microporous film layer.The composite fabric has excellent self flame-retardant performance; meanwhile, the flame-retardant performance cannot be gradually reduced over the use time; and in addition, the composite fabric layer has certain air permeability while realizing the waterproof performance.

Description

technical field [0001] The invention relates to a composite fabric and a preparation process thereof, in particular to a waterproof and flame-retardant composite fabric for an outdoor protective cover and a preparation process thereof, and belongs to the technical field of functional protective fabrics for outdoor equipment and its processing. Background technique [0002] Most of the large-scale equipment required for factory and field operations are directly exposed and placed on the open-air work site, which is convenient for direct operation during construction. When the equipment placed in the open air is outdoors for a long time, it needs to deal with weather changes, such as rainy and snowy weather, high temperature weather, etc. Therefore, it is necessary to install a protective cover on the outside of the equipment to protect the equipment from rain, snow and high temperature exposure; At the same time, because the equipment is placed on the ground, the ground will ...
