Embodiment Construction

[0016] A kind of respirator nylon material, it is made up of the raw material of following parts by weight:

[0017] Nylon 6130, glass fiber 30, triglycidyl isocyanurate 0.8, fatty alcohol polyoxyethylene ether 1, acetyl tributyl citrate 8, calcium zeolite 17, maleic anhydride 2, aluminum sulfate 1, hydroxystearic acid 2 , hexamethylphosphoric triamide 0.7, antioxidant 10100.6, polyisoprene 3, trimethylolpropane 0.4, ammonium persulfate 0.1, polydimethylsiloxane 0.6, calcium fluoride 2, polyphenylene And imidazole 0.8.

[0018] A preparation method of the respirator nylon material, comprising the following steps:

[0019] (1) Add the above-mentioned aluminum sulfate to deionized water 10 times its weight, stir evenly, add calcium zeolite, raise the temperature to 90°C, keep warm and stir until the water is dry, put it into 10mol / l sodium hydroxide solution, soak 2 hours, filter, wash the precipitate twice with water, dry at room temperature, and grind into fine powder to obt...

Abstract

The invention discloses a respirator nylon material. The respirator nylon material is prepared from, by weight, 130-200 parts of nylon 6, 30-40 parts of glass fiber, 0.8-2 parts of triglycidyl isocyanurate, 1-2 parts of fatty alcohol-polyoxyethylene ether, 8-10 parts of acetyl tributyl citrate, 17-20 parts of scolecite, 2-3 parts of maleic anhydride, 1-2 parts of aluminum sulfate, 2-4 parts of hydroxystearic acid, 0.7-2 parts of hexamethyl phosphoryl triamide, 0.6-1 part of antioxidant 1010, 3-4 parts of polyisoprene, 0.4-1 part of trimethylolpropane, 0.1-0.13 part of ammonium persulfate, 0.6-1 part of polydimethylsiloxane, 2-3 parts of calcium fluoride and 0.8-1 part of polybenzimidazole. Glass fiber is dispersed in the ethanol solution of polybenzimidazole, corrosion resistance is enhanced, added hexamethyl phosphoryl triamide can effectively improve the compatibility with all the raw materials and improve tenacity and stability of the finished product. The nylon material is high in antibacterial rot resistance and water resistance, high in surface strength and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of nylon materials, in particular to a nylon material for a respirator and a preparation method thereof. Background technique [0002] Waterproof and breathable valve, commonly known as respirator, breathable screw, etc., the outer shell is PA66+20% glass fiber raw material injection molding or brass is used as the hard support, and the outer shell is high temperature resistant silicone O-ring. The membrane material and the shell are combined through a variety of tight packaging processes, which have the characteristics of stable performance, simple installation, long service life, and high waterproof and breathable performance; [0003] Traditional breathable valve materials are mostly composed of nylon and glass fiber blends, and glass fiber is prone to problems such as poor dispersion as a reinforcing agent for nylon. Therefore, how to improve the compatibility of glass fiber in nylon or find new It is t...
