Abstract

The invention relates to heat-insulating materials and particularly discloses a rare-earth fireproof heat-insulating material. The rare-earth fireproof heat-insulating material contains the following ingredients in parts by mass: 20-30 parts of vitrified microbeads, 12-18 parts of aluminum silicate fibers, 8-13 parts of asbestos wool, 15-20 parts of pumice, 5-10 parts of kaolin, 2-5 parts of iron-doped titanium dioxide, 4-7 parts of sodium silicate, 5-10 parts of phenol-formaldehyde resin, 0.5-1 part of rare-earth additive, 2-5 parts of assistants and 60-80 parts of water. The invention further provides a preparation method for the rare-earth fireproof heat-insulating material. The rare-earth fireproof heat-insulating material prepared by the preparation method has good hydrophobicity and air permeability and excellent fire-proof and heat-insulating properties, thereby being suitable for being industrially produced on a large scale.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a rare earth fireproof thermal insulation material and a preparation method thereof. Background technique [0002] With the development of economy and society, people put forward higher requirements for the functions of building materials, and pay more and more attention to the functions of building materials such as structure, heat preservation, energy saving, environmental protection, waterproof, fire prevention, and anticorrosion. At present, the inorganic building materials used for exterior walls are heavy, have poor thermal insulation and fire resistance performance, poor impact resistance performance, and are easy to fall off, which cannot meet the requirements of modern buildings. [0003] Chinese patent application CN102875096A discloses a fire-proof and thermal insulation material for buildings, which is made of the following raw materials in parts by weight: 20-40 parts...
