Description

A kind of PVK load-transfer device framework material

Technical field

The utility model relates to load-transfer device framework material, relates to specifically a kind of PVK load-transfer device framework material.

Background technology

Short fiber be take as manufacture of materials in each PVK load-transfer device framework material manufacturer at present, but it is that the load-transfer device that material is made is difficult to produce a desired effect that warp-wise requires the pure short fiber of high load-transfer device to brute force, easily damage, and common PVK framework material fire retardancy is bad, is not suitable for colliery, mine and uses.

Summary of the invention

Problem to be solved in the utility model is for above problem, provides and is not easy to damage, and has a kind of PVK load-transfer device framework material of fire-proof function.

For addressing the above problem, the technical scheme that the utility model adopts is:

A kind of PVK load-transfer device framework material, comprise terylene layer, the two sides of described terylene layer are covered with respectively fire proofing firbre layer and lower fire proofing firbre layer, and upper fire proofing firbre layer is covered with upper rubber shoe latex layer away from a side of terylene layer, and lower fire proofing firbre layer is covered with lower rubber shoe latex layer away from a side of terylene layer; In described upper fire proofing firbre layer, be provided with some upper fire proofing firbre layer steel wire, in described lower fire proofing firbre layer, be provided with some lower fire proofing firbre layer steel wire; Described lower fire proofing firbre layer steel wire and upper fire proofing firbre layer gauge of wire are 0.05 millimeter.

As further improvement:

The thickness of described terylene layer is 2.5 millimeters; The thickness of described upper fire proofing firbre layer and lower fire proofing firbre layer is 2 millimeters.

Described terylene layer is formed by some warps and parallel braiding, and described parallel is by some terylene short fibers and long fine mixed being twisted into of terylene.

The parallel of the utility model terylene layer, by some terylene short fibers and long fine mixed being twisted into of terylene, will have been strengthened the intensity of broadwise when having guaranteed good groove forming character; Upper fire proofing firbre layer and lower fire proofing firbre layer have increased the utility model fire resistance.

Below in conjunction with accompanying drawing, the utility model is further described.
