Problems solved by technology

At present, there is no device and tool on the market that is necessary for people's daily life and has the function of protecting falling objects from heights. Therefore, it is very important to study an umbrella structure that can not only shade the rain but also effectively protect the human body from the damage caused by parabolic objects at high altitudes.

Embodiment 1

[0045] On the conveyor belt of the composite production line, unwind, stack, and lay flat 0.2mm silver tape, 0.08mm grid hot melt adhesive, 0.2mm aramid fiber, and 0.08mm grid hot melt adhesive from bottom to top , 0.1mm silver tape, the hot melt adhesive is EVA, and then sent to the infrared heating zone by the conveyor belt for preheating. Enter the hot pressing process, the temperature of the hot pressing roller is 120°C, and the hot pressing pressure is 8-15kg / cm 2 , hot-pressed from both sides at a constant speed, finally cooled to room temperature, and rolled.

Embodiment 2

[0047] On the conveyor belt of the composite production line, unwind, stack, and lay flat 0.2mm silver tape, 0.08mm grid hot melt adhesive, 0.2mm high-density polyethylene fiber, and 0.08mm grid hot melt from bottom to top. Melt glue, 0.1mm silver tape, hot melt glue is polyethylene, and then sent to the infrared heating zone via the conveyor belt for preheating, preheating temperature: heating zone 1: 80°C; heating zone 2: 80°C, heating for 30-90 minutes After that, it enters the hot pressing process, the temperature of the hot pressing roller is 75°C, and the hot pressing pressure is 15-25kg / cm 2 , hot-pressed from both sides at a constant speed, finally cooled to room temperature, and rolled.

Embodiment 3

[0049]On the conveyor belt of the composite production line, unwind, stack, and lay flat 0.2mm pearlescent cloth, 0.08mm mesh hot melt adhesive, 0.2mm high-density polyethylene fiber, and 0.1mm mesh hot melt from bottom to top. Melt glue, 0.2mm high-density polyethylene fiber, 0.1mm grid hot melt glue, 0.1mm nylon cloth, hot melt glue is polyethylene, and then sent to the infrared heating zone for preheating through the conveyor belt, preheating temperature: heating Zone 1: 80°C; Zone 2 heating: 80°C, after heating for 30-120 minutes, then enter the hot-pressing process, the temperature of the hot-pressing roller is 75°C, and the hot-pressing pressure is 15-25kg / cm 2 , hot-pressed from both sides at a constant speed, finally cooled to room temperature, and rolled.

Abstract

The invention provides umbrella cloth adopting a high-strength composite material. The umbrella cloth comprises a first waterproof layer, a first hot melt adhesive layer, one or more high-strength fiber layers, a second hot melt adhesive layer and a second waterproof layer which are arranged in an overlapped paving manner from bottom to top. If a plurality of high-strength fiber layers are adopted, a hot melt adhesive layer is laid between each adjacent two high-strength fiber layers; the first waterproof layer and the second waterproof layer are one of silver plaster, pearl finished fabric, nylon cloth and pongee cloth; the hot melt adhesive adopted by the first hot melt adhesive layer and the second hot melt adhesive layer and the hot melt adhesive layers laid between the adjacent high-strength fiber layers adopt one or a mixture of more than one of the following substances: EVA, polyamide, polyether sulfone resin, polyethylene and polyesteramide; and the high-strength fiber layers are carbon fibers, aramid fibers, high-density polyethylene, and glass fiber woven cloth, or the woven structure of any two or three of the carbon fibers, aramid fibers, high-density polyethylene, andglass fiber woven cloth. With the umbrella cloth adopting the high-strength composite material, the injuries caused by objects falling from high altitude to the human body can be effectively prevented.

Description

technical field [0001] The invention relates to the field of umbrella cloth, in particular to a novel anti-falling object umbrella cloth and a manufacturing method thereof. Background technique [0002] The high-altitude parabolic phenomenon was once called "the pain hanging over the city". In the "Shanghai Bad Habits Ranking List", it ranks second with "littering". Parabolic throwing at high altitude is an uncivilized behavior and will bring great social harm. While people are lamenting the premature death of a hundred-day baby girl and the grief of their parents, a social issue about the threat of parabolic objects in the city to people's "overhead safety" has once again aroused people's heated discussions. An egg thrown from the 8th floor can break your scalp. A nail fell from the 18th floor and may be inserted into the brain of a pedestrian. Even if it is a piece of watermelon rind, when it is thrown from the 25th floor, people may be killed on the spot, because this...
