Abstract
The invention relates to a novel building thermal insulation material of internal and external walls. The thermal insulation material is characterized by comprising the following materials in percentage by weight: 5% to 7% of magnesium chloride, 45% to 50% of magnesium oxide, 10% to 15% of polystyrene, 15% to 20% of high calcium fly ash, 10% to 15% of water, 4% to 5% of color paste and 2% to 5% of smashed glass filaments. Then, the materials in accordance of the ratio mentioned above are evenly stirred and compressed into finished heat preservation products in accordance of the shape of moulds. The unit weight of the product produced by adopting the building insulation material of internal and external walls is less than or equal to 200 kg/m<3>. The thermal conductivity of the product is less than 0.045 W/m.k. The operating temperature of the product is less than 550 DEG C. The compressive strength of the product is greater than or equal to 0.550 mpa. The product has a good affinity to the cement mortar and the characteristics of light unit weight, good thermal insulation property, fire resistance and water tolerance, and high intensity. The material is applicable to the inside and outside heat preservation of brick and concrete walls, and the heat preservation of flat roofs and balconies, and is particularly applicable to the heat preservation of sloping roofs.
Description
Technical field
The invention belongs to construction material, particularly to a kind of novel inner-outer wall building thermal insulation material.
Background technology
At present, domestic construction thing roofing, materials for wall affect requirement to have good thermal and insulating performance due to very big by indoor/outdoor temperature-difference.The conventionally employed Aerated Concrete of building external and internal wall, hollow brick, perlite, cement block fill out block in the prior art；Or adopt centre outer within the walls outside to fill out the method building benzene plate, or make skeleton with steel bundle and pack benzene plate, then smear cement and build the method filled.Above-mentioned material exists in construction that materials are many, it is numerous and diverse to construct, heat insulation effect is poor, adopts benzene panel material to there is intensity difference, do not prevent fires and cement mortar not affinity, the shortcoming such as be easily generated crackle, come off.
Summary of the invention
Instant invention overcomes the defect of above-mentioned existence, it is therefore an objective to for solving construction material insulation, heat-proof quality is good, easy construction, the body gently high-strength performance requirement such as good with cement mortar affinity, it is provided that one novel inner-outer wall building thermal insulation material.
Novel inner-outer wall building thermal insulation material content Description of the present invention:
Novel inner-outer wall building thermal insulation material of the present invention, it is characterised in that: it is made up of llowing group of materials percentage ratio by weight: magnesium chloride 5～7%, magnesium oxide 45～50%, polystyrene 10～15%, high-calcium fly ass 15～20%, water 10～15%, mill base 4～5%, cullet silk 2～5%.
Take llowing group of materials by weight: magnesium chloride 6, magnesium oxide 456, polystyrene 106, high-calcium fly ass 18, water 15, mill base 4, cullet silk 5, the shape presswork heat insulating products of mould after the material uniform stirring of aforementioned proportion, will be pressed
Adopt inner-outer wall building thermal insulation material goods unit weight≤200kg/m that inner-outer wall building thermal insulation material of the present invention is made3, heat conductivity < 0.045W/m.k, use temperature<550℃, comprcssive strength >=0.550mpa, have good affinity with cement mortar, have the advantages that unit weight is light, thermal and insulating performance good, fire-resistance is water-fast, intensity is high.Suitable in brick wall, the interior external thermal insulation peace roofing of concrete walls, balcony insulation, it is particularly suited for Sloping roof insulation.
Detailed description of the invention
Novel inner-outer wall building thermal insulation material of the present invention is achieved in that and illustrates below.
Inner-outer wall building thermal insulation material is adopted to prepare heat insulation material product, percentage ratio by weight takes llowing group of materials: magnesium chloride 6, magnesium oxide 456, polystyrene 106, high-calcium fly ass 18, water 15, mill base 4, cullet silk 5, will construct by the shape presswork heat insulating products of mould after the material uniform stirring of aforementioned proportion.
Adopting light high-strength thermal-insulation material for builidng goods of the present invention, after testing, whole conformance with standard specify, unit weight≤200kg/m3, heat conductivity < 0.045W/m.k, use temperature<550℃, comprcssive strength >=0.550mpa, have good affinity with cement mortar, have the advantages that unit weight is light, thermal and insulating performance good, fire-resistance is water-fast, intensity is high.Suitable in brick wall, the interior external thermal insulation peace roofing of concrete walls, balcony insulation, it is particularly suited for Sloping roof insulation, good through the test thermal and insulating performance of two years cold and hot change after using.
