Abstract

The invention discloses a building wallboard, in particular relates to a cement-polyphenyl granule foamed heat preservation board and a preparation method thereof. The cement-polyphenyl granule foamed heat preservation board is prepared from the following raw materials in parts by weight: 150-160 parts of cement, 1.5-2 parts of flame retardant polyphenyl granule, 0.8-1.2 part of fiber, 6-6.5 parts of foaming agent, 2-3 parts of foam stabilizer, 2.5-3.5 parts of emulsion, 1.5-2.5 parts of waterproof agent and 100-120 parts of warm water at 50-60 DEG C. The heat preservation board provided by the invention is light in dead weight, low in heat preservation coefficient, good in sound insulation effect and good in compressive strength. The specification and dimension of the heat preservation board can be randomly cut, so that the cost is low and the operative molding is convenient; and the heat preservation board can be randomly cut according to the construction demand, so that great convenience is brought to the building construction.

Description

Technical field [0001] The present invention involves a building wall board, especially a cement, polyophenylene particle foam insulation board and their preparation methods with low insulation coefficients, low insulation coefficients, and good sound insulation effects. Background technique [0002] The foam insulation board, also known as the gas -added concrete board, has the advantages of high insulation efficiency and good sound absorption, which can be made into outer wall boards and interior wall boards.It is mainly made of cement as the main raw material, which is heavy.The existing technologies are 200-300 kg per cubic meter and the heat conduction coefficients are above 0.06.The specifications of the existing thermal insulation board made of cement as the main raw material are one -time molding. There are many styles of the mold, it is not easy to change, and the cost is high. [0003] China Patent with CN102746021A for application announcement, and a chemical foaming c...
