Thin-layer fireproof thermal-insulating material

Abstract

The invention discloses a thin-layer fireproof thermal-insulating material which comprises Portland cement, high-aluminum cement, water, acrylic acid and calcium carbonate. The material has the beneficial effects that the Portland cement and the high-aluminum cement are adopted as adhesives, silica aerogel powder is adopted as a thermal-insulating material, aluminum hydroxide and magnesium hydroxide are adopted as flame retardants, the components are compounded according to a certain ratio, underground fire hazards, heat damage and danger of operators and equipment can be effectively solved, and functions of fire prevention and thermal insulation can be achieved.

Description

technical field [0001] The invention belongs to the technical field of fireproof materials, and relates to a thin-layer fireproof and heat-insulating material. Background technique [0002] Shotcrete is widely used as an economical and effective method in underground mine and tunnel support. However, with the advancement of science and technology, chemical engineers have invented a new type of thin-layer support material. The thin-layer support material is considered to be It can replace traditional support techniques such as anchor mesh and shotcrete, and has gradually been approved and applied in mines. In addition, the underground is prone to fire and there are many heat-generating areas, and the traditional sprayed concrete cannot achieve the function of fire prevention and heat insulation. Contents of the invention [0003] The object of the present invention is to provide a thin-layer fire-proof and heat-insulating material. The beneficial effect of the present inv...
