Embodiment 1

[0020] Gypsum foam insulation building material, its specific preparation method is as follows:

[0021] Take 100kg of construction gypsum, 60kg of Portland cement, and 0.5kg of polypropylene fiber that meet the stated parts by weight, mix and stir evenly, and then add 2kg of styrene-acrylic emulsion, 2kg of silicone waterproofing agent, and 0.04 kg of 107 glue that meet the stated parts by weight. kg and 100kg of warm water at 50°C and continue to stir until it becomes a slurry, then add 6kg of hydrogen peroxide that meets the stated weight parts, pour it into the mold for rise, foam in 5 minutes, and let it settle in place. After waiting for 10 minutes, demould. After curing for 10 days, a gypsum foamed thermal insulation building material was obtained. The length of polypropylene fiber is 8-9mm.

[0022] The gypsum foam insulation building material prepared in this example has a dead weight of 190 kilograms per cubic meter, a thermal insulation coefficient of 0.06, and a s...

Abstract

The invention discloses a thermal insulation building material and particularly relates to a gypsum foaming thermal insulation building material and a preparation method thereof. The gypsum foaming thermal insulation building material is prepared from the following raw materials in parts by weight: 100 parts of building gypsum or desulfurization gypsum, 40-60 parts of Portland cement, 0.5-1.5 pats of fibers, 6-10 parts of foaming agent, 2-4 parts of emulsion, 2-4 parts of waterproof agent, 0.04-0.06 part of thickener and 100-140 parts of 40-50 DEG C warm water. The gypsum foaming thermal insulation building material has the advantages of light dead weight, low thermal insulation coefficient, good soundproof effect, low cost and is convenience to machine and use.

Description

technical field [0001] The present invention relates to a thermal insulation material for building, in particular to a gypsum foam thermal insulation building material and its preparation method, which can be made into decorative partition wall panels, thermal insulation blocks, fire doors with light weight, good thermal insulation and sound insulation effects Core materials, color steel sandwich panels, roof insulation panels, composite panels and various filling materials. Background technique [0002] Building insulation materials with gypsum as the main raw material mainly include gypsum hollow blocks, gypsum hollow inner wall panels and other products. Thermal insulation blocks are also called aerated concrete blocks. Wall blocks, insulation blocks and interior wall panels, etc. Most of the existing thermal insulation blocks are made of cement as the main raw material, and the dead weight is relatively heavy. The insulation material with gypsum as the main raw materi...
