Abstract
Description
technical field
[0001] The invention relates to a wallboard, more specifically, a foamed lightweight partition wallboard and a preparation method thereof. Background technique
[0002] In house construction, especially in alpine regions, a large amount of heat in the house is dissipated through the roof and walls. Therefore, it is necessary to pave insulation boards on the roof and outer walls to play the role of thermal insulation and energy saving. Existing extruded insulation boards have the disadvantages of low strength, low compression resistance, low density, weak aging resistance, and high cost. New products need to be launched to participate in the competition. Contents of the invention
[0003] The object of the present invention is to provide a foamed lightweight partition wall board and a preparation method thereof.
[0004] The technical scheme adopted in the present invention is:
[0005] A foamed lightweight partition wall is characterized in that it is ma...
Examples
Embodiment Construction
[0013] A foamed lightweight partition board made of the following raw materials in parts by weight (kg):
[0014] Medium-density polyethylene 120, metallocene linear low-density polyethylene 35, cellulose acetate 14, iron slag powder 40, glass fiber 12, sodium dodecylbenzene sulfonate 5, quartz sand 50, phosphogypsum 14, pulverized coal Ash 24, straw powder 10, waste engine oil 2, municipal sludge powder 10, dipropylethanolamine 2, modified loess powder 35, Freon 4.
[0015] The modified loess powder is prepared from the following raw materials in parts by weight (kg): loess 120, plant ash 30, waste engine oil 10, starch 12, sodium dodecylbenzene sulfonate 2, aluminum powder 0.3, and an appropriate amount of water;
[0016] The preparation method is as follows: calcining the loess at 460-480°C for 2-3 hours, and grinding it into powder; adding starch and sodium dodecylbenzenesulfonate to an appropriate amount of water, and heating to form a paste; adding the above-mentioned C...
