Problems solved by technology

However, ordinary silicon cement is often used as the main cementitious material in traditional fireproof building materials. Although it has the advantages of high strength and good durability, its large volume and poor heat insulation performance limit its application range. The transportation cost is increased in the process, and the construction difficulty is also increased in the construction process, and there are also certain safety hazards

Abstract

The invention discloses a preparation method of a fire-proof light-weight building material. The preparation method comprises the following steps: in parts by weight, weighing 20-40 parts of silicon micropowder, 10-30 parts of sepiolite powder, 8-20 parts of fly ash and 40 parts of water, mixing, then performing ultrasonic treatment, then sequentially adding 25-55 parts of a filler, 2-10 parts ofmodified bisphenol A-type epoxy resin, 0.2-1 part of sodium sulfate, 0.2-1 part of phenolic modified aromatic amine and 8-14 parts of hydroxypropyl methylcellulose, and mechanically stirring; pouringa slurry B obtained after ball milling into a moulding mould, statically curing, and then demoulding to obtain a blank C; placing the blank C in an autoclave, preserving heat, and naturally cooling toobtain the fire-proof light-weight building material. By the preparation method, a technology is simple and the production cost is low; the fire-proof light-weight building material prepared by the preparation method provided by the invention is light in weight, has excellent fire-proof and heat-insulating performance and has a wide market prospect.
