Embodiment Construction

[0024] In the present invention, the cement substrate is used as the foundation of the refractory board, and the cement substrate is a dried fiber cement board or a skeleton structure of inorganic materials; the thickness of the board is 5 mm to meet the needs, but the surface of the substrate is required to be rough and not polished.

[0025] Dimensions: 1200 / 2400×300 / 600×(10 / 20 / 50120)mm; the structure within the outer frame of the skeleton can adopt balanced structures such as "field", "feng" and "well".

[0026] Wet expansion rate: ≤0.23%;

[0027] Moisture content: ≤10%, usually 5%

[0028] Drying temperature: 50±5℃

[0029] Deviation limit: length ±5mm

[0030] Width ±3mm

[0031] Thickness ±2mm

[0032] Concrete hollow wall panels: ordinary panels, door frame panels and lintel panels;

[0033] The board length, width and thickness conform to the building modulus, the board length is within 3000mm, and the board width is 300 / 600mm;

[0034] Partition wall thickness ...

Abstract

The invention discloses a making method of a fireproof thermal insulation and noise reduction composite wallboard. The method includes the steps of: 1, coating a cement matrix side exposed to fire with a fireproof cover layer; 2, conducting foaming hardening; and 3, conducting alkali resistant treatment outside the fireproof cover layer. Specifically, the slurry of the fireproof cover layer is formed by mixing of high-alumina cement, refractory aggregate, a water / liquid admixture, and a foaming agent. The fireproof thermal insulation wallboard produced by the making process involved in the invention has fireproof and thermal insulation performance much higher than that the commonly used products at present, and can meet the requirements of buildings with higher fireproof requirements.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fireproof board. Background technique [0002] Fire-resistant wallboard is a commonly used building material. In the event of a fire, it can effectively inhibit the spread of fire. Most of the current fire-resistant wallboards are made of base paper (titanium powder paper, kraft paper) that has been impregnated with melamine and phenolic resin. High temperature and high pressure . After thermosetting, melamine resin has high surface hardness, wear resistance, high temperature resistance, impact resistance, small surface pores and is not easy to be polluted, solvent resistance, water resistance, chemical resistance, flame resistance and other mechanical strength. This type of fire-resistant board only has a certain fire-resistant performance, and it is difficult to meet the needs of buildings with high fire-proof requirements.
