Fireproof insulation filler

Abstract

The invention relates to the field of building materials, in particular to a fireproof insulation filler used for insulation of an internal wall. The filler comprises the following raw materials in parts by weight: 20-25 parts of magnesium sulfate, 40-50 parts of magnesium oxide, 15-25 parts of glass beads, 10-20 parts of tourmaline particles, 10-20 parts of natural germanite particles, 15-30 parts of bamboo carbon fiber, 5-10 parts of a foaming agent and 30-40 parts of flame-retardant polyurethane foaming particles. The filler is excellent in fireproof capacity, and has a soundproof effect; tourmaline and natural germanite can release infrared rays and negative ions; the bamboo carbon fiber can absorb toxic and harmful gas in air; a living environment can be effectively improved; and health of resident people is ensured.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fireproof and thermal insulation filler for interior wall thermal insulation. Background technique [0002] With the development of my country's construction industry, the demand for thermal insulation materials is increasing, and the requirements for fire protection rating are also getting higher and higher. As the name suggests, the fireproof insulation board has both the function of fire prevention and heat preservation. In buildings, the fireproof insulation board is covered with non-combustible and fire-resistant plates outside the steel structure (beams and columns) in a specific way of connection, fixing and combination. Thereby delaying the rapid temperature rise of the steel and reducing the strength when the fire occurs, avoiding the collapse of the building or structure caused by the loss of the steel structure's supporting capacity, and the good thermal insulation ...
