Detailed Description

Fig. 1 is a schematic structural view of the present invention, and fig. 2 is an enlarged view of a composite honeycomb unit structure of the present invention; fig. 3 is an enlarged view of the composite honeycomb structure of the present invention. The sole of the fire protection boot of the embodiment comprises a cushion layer 1, a heat insulation layer 2, a composite honeycomb structure layer 3 and an outsole 4 which are bonded and fixed into a whole in sequence from top to bottom, wherein the composite honeycomb structure layer 3 is composed of a plurality of composite honeycomb hole units, each composite honeycomb hole unit is composed of a diamond hole 31 and a circular hole 32 which is distributed on four nodes of the diamond hole 31 in a plane mode, and two adjacent edges of the diamond hole 31 are connected to different positions of the circular hole 32 respectively; the heat insulation layer 2 is formed by mixing glass fiber with a three-dimensional porous through structure and flame-retardant heat insulation rubber, and the flame-retardant heat insulation rubber is filled in the three-dimensional through hole of the three-dimensional porous metal fiber to form a composite compact structure; the cushion layer 1 is made of an ultrahigh molecular weight polyethylene fiber membrane fabric and cotton fibers in a composite mode, the cotton fiber material layer is located on the upper layer of the cushion layer 1 and is close to the skin of a human body, comfortability and air permeability are enhanced, and the ultrahigh molecular weight polyethylene fibers have good impact resistance, soft bending property and wear resistance and are strong in energy absorption; the heat insulation layer 2 plays a role in heat insulation and temperature resistance, and the heat insulation layer 2 also has impact resistance, so that the strength of the heat insulation layer 2 is enhanced; the composite honeycomb structure layer 3 is the key for enhancing heat insulation, high temperature resistance and rigidity of the sole and can ensure extremely high comfort, the composite honeycomb structure layer 3 is formed by uniformly distributing cell elements formed by diamond holes 31 and round holes replacing diamond nodes of the diamond holes 31, therefore, the special honeycomb structure can not deform and has good energy absorption effect in the long-term use process, and has certain impact resistance.

In the embodiment, the distance between two circle centers of the composite honeycomb hole unit along the side of the diamond is 4-6 mm; the position distribution of the diamond holes 31 and the round holes and the sizes of the holes directly determine the strength of the honeycomb structure, the distance between the diamond holes 31 and the round holes is too long, deformation resistance is affected, the distance is too small, and an energy recovery effect cannot be achieved, so that the proper size is guaranteed for rigidity and energy absorption performance, and the purpose of light weight is achieved.

In this embodiment, the diameter of the circular hole 32 is 2-4 mm; the combination of the circular holes 32 and the diamond holes 31 enhances the rigidity of the composite honeycomb structure and improves the deformation resistance.
