Abstract

The invention relates to the field of flame-retardant materials and particularly provides a preparation method of a novel fire-resistant flame-retardant material. The preparation method comprises thefollowing steps: preparing raw materials consisting of, by mass, 15%-35% of paraffin, 12%-21% of a flame-retardant mixed filler, 1%-4% of a flexibilizer, 2%-7% of vulcanized rubber, 12%-25% of epoxy resin and 30%-45% of deionized water; treating the raw material vulcanized rubber to form vulcanized rubber threads with diameters in a range of 0.3-0.7 mm and a length of 8-13 mm for subsequent use; cleaning and drying the raw material flame-retardant mixed filler, and grinding the flame-retardant mixed filler with a grinder to obtain flame-retardant mixed filler powder for subsequent use; dicingthe paraffin, adding the epoxy resin, carrying out mixing at 50-88 DEG C, sequentially adding the deionized water, the flame-retardant mixed filler powder, the vulcanized rubber threads and the flexibilizer, and carrying out mixing; and after the completion of mixing, cutting a mixed product into single products and carrying out packaging. By optimizing conventional preparation methods, the preparation method of the invention allows auxiliary materials to be well dispersed into the whole product, so the prepared novel fire-resistant flame-retardant material has good high-temperature performance.

Description

technical field [0001] This application relates to the field of material engineering, in particular to a preparation method of a novel fire-resistant and flame-retardant material. Background technique [0002] Fireproof materials refer to various materials that play an absolute role in modern fire prevention and are mostly used in buildings. Commonly used fireproof materials include fireproof boards, fireproof doors, fireproof glass, fireproof paint and fireproof bags, etc. It also includes some polymer materials, which are also modified to improve the fire and flame retardant effect. For example, fireproof sealing materials, which are used to seal various penetrations, such as various openings formed when cables, air pipes, oil pipes, natural gas pipes, etc. The segmented fire separation of bridges prevents the fire from spreading through these openings and gaps. It has fire protection function and is easy to install. It includes organic fireproof blockage, inorganic fire...
