An expanded vermiculite lightweight thermal insulation wall block

Abstract

A provided expanded vermiculite lightweight thermal insulation wall block includes bed material, medium material, surface material and a grid cloth, the fabric and the bed material are prepared from the following components, by weight: 100 parts of sulphoaluminate cement, 2-8 parts of fly ash, 0.5-3 parts of iron oxide yellow, 0.5-2 parts of silica fume, 2-6 parts of expanded vermiculite, 1-2 parts of mekralon, 0.05-0.1 part of trisodium phosphate, 0.01-0.02 part of organosilicon and 35-50 parts of water; the medium material is prepared from the following components, by weight: 100 parts of the sulphoaluminate cement, 2-8 parts of the fly ash, 0.5-2 parts of the silica fume, 15-25 parts of the expanded vermiculite, 1-5 parts of a polystyrene granule, 0.05-0.1 part of the trisodium phosphate, 0.001-0.01 part of oxalic acid, 0.01-0.02 part of the organosilicon, 0.01-0.015 part of sodium butylnaphthalenesulfonate, and 30-40 parts of the water. The wall block has the advantages of low cost, high strength, long service life, excellent insulation and sound insulation effect, and light weight.

Description

technical field [0001] The application relates to a lightweight partition wall board, in particular to a lightweight thermal insulation wall block of expanded vermiculite. Background technique [0002] Vermiculite (Mg, Ca) 0.3-0.45 (H2O) n {(Mg, Fe3, Al) 3 [(Si, Al) 4O12] (OH) 2}. The name of vermiculite mineral comes from Latin, with the meaning of "worm-like" and "worm track". Vermiculite gets its name from the fact that vermiculite exfoliates like a worm along the c-axis of its crystals when suddenly heated to 200 to 300°C. Vermiculite is a layered structure of magnesium-containing water Aluminosilicate Secondary metamorphic minerals look like mica, usually mainly formed by hydrothermal alteration or weathering of black (gold) mica, because it is deflected when it loses water and expands when heated, and its shape resembles a leech, so it is called vermiculite. Raw vermiculite flakes were subjected to high temperature roasting rear volume expansion The final vermic...

Problems solved by technology

The cement board is heavy and cannot be moved at will, and can only be used as a fixed wall and platform

[0005] In the prior art, ordinary silicon cement is mostly used as the main raw material for lightweight cement boards, because it is widely used, but its setting time is long and the strength growth is slow. If it is mass-produced as cement boards, the production efficiency will be greatly reduced
