Embodiment 1

[0023] Add 70 grams of polybutylene adipate (PBA2000), 20 grams of TDI, and 5 grams of silicone oil 7162 (Shanghai Heying Chemical Co., Ltd.) into the flask, react at 85 ° C for 1.5 hours, cool to 70 ° C, add 2.7 gram of dimethylolpropionic acid (DMPA), 6 grams of diethylene glycol, insulated and stirred for 30 minutes, added 50 grams of acetone, added dropwise 5 drops of dibutyltin dilaurate, kept at 60°C for 4.5 hours, and dropped to Stir at room temperature, add 2 grams of triethylamine to neutralize, then add 2 grams of KH550, and finally add 100 grams of 10% nano-nickel-zinc-ferrite aqueous slurry and 2 grams of organic phosphorus flame retardant dimethyl phosphate 1. Organosilicon waterproofing agent MH-1109 2.5 grams and 700 grams of ionized water are stirred, and the acetone is removed to obtain a flame-retardant, waterproof, breathable and wave-absorbing coating glue.

Embodiment 2

[0025] Add 60 grams of polycaprolactone (PCL1000), 22 grams of IPDI, and 5 grams of silicone oil 7162 (Shanghai Heying Chemical Co., Ltd.) into the flask, react at 85°C for 1.5 hours, cool down to 75°C, and add 2.7 grams of dimethylol Propionic acid (DMPA), 6 grams of diethylene glycol, heat and stir for 30 minutes, add 55 grams of acetone, drop 5 drops of dibutyltin dilaurate, keep warm at 60 ° C for 4.5 hours, drop to room temperature, add 2 gram of triethylamine to neutralize, then add 1.5 grams of KH560, finally add 80 grams of 8% nano-barium titanate aqueous slurry, organic halogen flame retardant 1,2-bis(2,4,6-tribromophenoxy Base) 2 grams of ethane, 2.5 grams of organic fluorine water repellent WP-7 and 800 grams of ionized water, stir, remove acetone, and obtain a flame-retardant, waterproof, breathable and wave-absorbing coating glue.

[0026] The coating glue prepared by the invention has a glossiness of 90-95 and a tensile strength of 35-45Mpa.

Abstract

The invention relates to a preparation method for inflaming retarding waterproof breathable microwave absorbing coating adhesives of military apparatus shell textile fabrics. The invention is characterized in that: diisocyanates, hydroxyl methyl silicone oils and polyester polyatomic alcohols are used for generating prepolymers with a terminal group of -NCO; dihydric dimethyl propanoic acids and diglycols are used for chain extension reaction; salifying agents are used for adjusting PH value to neutrality; silane coupling agents are added for end capping; water-based sizing agents of nano microwave absorbing agents, flame retardant agents and waterproofing agents are added into mixture and mixed with deionized water, and then the inflaming retarding waterproof breathable microwave absorbing coating adhesives are obtained. The microwave absorbing coating adhesives of the invention are emulsion which takes monocomponent water-based polyurethanes as main body, and microwave absorbing materials are added into the emulsion. The textile fabrics using the coating adhesives have the advantages of soft hand feeling, water resistance and ventilation, absorption of specified wavelength, functions of electromagnetic radiation resistance, static resistance and absorption of electromagnetic waves, and high flame retardance, and are good military microwave absorbing materials.

Description

technical field [0001] The invention relates to a method for preparing a flame-retardant, waterproof, breathable and wave-absorbing coating glue for military equipment outer cover fabrics, which can be used in the fields of radiation protection, electromagnetic wave interference and the like for military fabrics. It belongs to the technical field of textile auxiliaries. Background technique [0002] Before the present invention was made, the conventional equipment outer cover fabrics only had ordinary wave-absorbing functions, and did not have multi-functional functions such as flame-retardant, waterproof, and breathable. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a method for preparing a flame-retardant, waterproof, breathable and wave-absorbing coating glue for military equipment outer cover fabrics with obvious flame-retardant effect, waterproof and breathable effect. [0004] The ...
