Embodiment approach

[0044] A modified aramid short fiber flame retardant thermoplastic board. The raw materials of the modified aramid short fiber flame retardant thermoplastic board are composed of thermoplastics and modified aramid short fiber flame retardant. The above-mentioned thermoplastic is 94.3%, and the modified aramid staple fiber flame retardant is 5.7%;

[0045] The raw material preparation method of the flame-retardant thermoplastic is:

[0046] The temperature of the internal mixer is controlled at 168°C, and the rotational speed is 550 rpm, and the thermoplastic is added to the internal mixer, and the additive flame retardant is added after it is melted, and melted and blended for 12 minutes to obtain a flame-retardant thermoplastic material. Place it in an environment of 25°C and a relative humidity of 60% for 60 hours to form;

[0047] The material is pressed into a plate body, the plate body includes a first plate body 1, a second plate body 2 is movably connected to one side ...

Abstract

The invention discloses a modified aramid short fiber flame-retardant thermoplastic plastic plate. Aramid short fibers are firstly activated and then modified with an RFL tackified two-bath dipping treatment technology, the proportions of a first-bath dipping solution, second-bath RF resin and an RFL dipping solution and technological parameters of the dipping treatment are repeatedly experimented, specific parameters are determined, and the best bonding effect is achieved. The plastic plate comprises a first plate body, wherein a second plate body is movably connected with one side of the first plate body, a fixed block is fixedly connected with the outer surface of one side, close to the first plate body, of the second plate body, and a limit plate is fixedly connected with the position,close to the second plate body, of the outer surface of one side of a sleeve. By means of a series of structures, the plastic plate has better assembling and disassembling property in a using process, a fixing mode is relatively invisible, meanwhile, convenience can be brought to a user for assembling and disassembling, transportation is facilitated, the service life of the first plate body can be prolonged, and the plastic plate is convenient to use by the user.

Description

technical field [0001] The invention relates to the technical field of plastic boards, in particular to a modified aramid short fiber flame-retardant thermoplastic board. Background technique [0002] Aramid fiber is a new type of high-tech synthetic fiber, which has the characteristics of soft texture, low density, high strength, high modulus, high temperature resistance, etc. It can be used for more than 10 years at a temperature of 220 degrees, and can be used at a temperature of 560 degrees. Does not decompose, does not melt. Because of its characteristics, it can be used in engineering and is widely used by people. [0003] Thermoplastic polyurethane elastomer (TPU) is one of the most commonly used plastics in the world. It combines the processing performance of plastics and the physical and mechanical properties of rubber. It has high elasticity, high strength, high wear resistance, radiation resistance, Oil resistance, low temperature brittleness resistance, and mec...
