Abstract
The invention provides a sound insulation building material and a preparation method thereof. The sound insulation building material is prepared from, by weight, 80-100 parts of cement, 10-20 parts of wood bits, 5-10 parts of fire retardant, 1-2 parts of activated carbon and 10-20 parts of straw particles. In the preparation process, the wood bits, the fire retardant, the activated carbon and the straw particles are added to the cement, and even mixing is carried out. The problems that in the prior art, the sound insulation effect is poor, and cost is high are solved, and the material is environmentally friendly.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of soundproof construction composition that effectively can improve soundproof effect.
Background technology
Every material of construction that can be used for block noise, is referred to as Sound insulation for building material.Sound-proof material kind, daily people compare and common are solid fragment of brick, reinforced concrete wall, plank, plasterboard, iron plate, sound-insulating felt, fiberboard etc.Stricti jurise is said, nearly all material all has deadening, and its difference is exactly the varying in size of sound-damping qualities between differing materials.Commaterial, because area density is different, there is larger change in its sound-damping qualities.Most countries the eighties and former building, partition wall adopts clay brick mostly, and the oise insulation factor of 240mm clay tile wall is at more than 50dB, and defening effect is good.But current building partition there occurs the change of essence. on the one hand, in order to environmental protection needs, building prohibits the use clay brick, because make clay brick can destroy arable land; On the other hand, because novel building system and Highrise buildings require from heavy and light, make curtain wall structure trend towards the oise insulation factor of frivolous Light Wall general lower, individual layer wall does not generally all reach 50dB. usually at below 45dB, and this is poor compared with traditional clay tile wall with regard to making defening effect.
Partition material conventional at present and component mainly contain 5 large classes, and their sound insulation situation is substantially as follows:
(1). concrete walls
The oise insulation factor of the cast-in-place solid reinforced concrete wall of more than 200mm thickness and the oise insulation factor of 240mm clay tile wall close, the oise insulation factor of the thick concrete walls of 150 ~ 180mm is about 47 ~ 48dB, but the reinforced concrete multi-hole board of area density 200kg/m2, oise insulation factor is at below 45dB.
(2). blockwork
Building block kind is more, and dividing by function has load-bearing and non-bearing building block.Conventional building block mainly contains concrete hollow and the solid blocks such as haydite, flyash, slag, sandstone; The building block such as gypsum, Calucium Silicate powder.
The oise insulation factor of blockwork is different along with the difference of the gravimetric thickness of body of wall.The bearing building block wall that area density is close with clay tile wall, its sound insulation property and clay tile wall are also close substantially. and sand-cement slurry light block of plastering fills the sound insulation property of partition wall, depending on the thickness of surface of wall coat of plaster to a great extent. the oise insulation factor after 15mm ~ 20mm solid cement mortar is respectively smeared on two sides is about 43 ~ 48dB, and area density is less than the oise insulation factor of the light block wall of 80kg/m2 usually at below 40dB.
(3). bar board wall
The usual thickness of batten of building partition wall by laying bricks or stones is 60mm ~ 120mm, and area density is generally less than 80kg/m2, possesses the advantage such as light weight, easy construction.
Bar board wall carefully can divide two classification again into: a class is with inorganic coagulation material and the solid or porous batten made that gathers materials, as (enhancing) light aggregate concrete plate, steam-pressing aero-concrete batten, woven wire haydite concrete batten, gypsum lath etc., the oise insulation factor of this kind of individual layer light lath wall is usually between 32 ~ 40dB; Another kind of is the prefabricated sandwich batten be combined in advance in factory by close-knit surface material and light-weight filler, as concrete rock wool or polyphenyl sandwich batten, fiber cement board light-weight laminboard etc.The oise insulation factor of prefabricated sandwich bar board wall is usually between 35 ~ 44dB.
(4). thin plate composite wall
Thin plate composite wall at the construction field (site) thin plate is fixed on the both sides of keel and the Light Wall formed.Gauge of sheet is generally at 6mm-12mm, and thin plate is used as body of wall surface layer plate, fills rock wool or glass wool between wall keel.Thin plate kind has Thistle board, fibrous plaster, fiber cement board, calcium silicate board with microporous, calcium magnesium plate etc.
The oise insulation factor of thin plate own is not high, the oise insulation factor of single plate is between 26 ~ 30dB, and the double layer hollow wadding combined wall that they and Lightgage Steel Joist, rock wool (or glass wool) form, but good defening effect can be obtained. their oise insulation factor is usually between 40 ~ 49dB. and increase the thin plate number of plies, the oise insulation factor of wall can be greater than 50dB.
(5). the core board wall of on-the-spot spraying cement mortar surface layer
Such partition wall is at the construction field (site) after mounting finished product core plate, then at the multiple cement screedn of core plate two sides spray.Conventional core plate has steel wire net rack styrofoam, steel wire net rack rock cotton board, plastic hollow inner formword.
The oise insulation factor of this kind of body of wall is relevant with core type and cement sand pulp layer thickness, and their oise insulation factor is usually between 35 ~ 42dB.
In sum, have the light partition wall sound insulation property of quite a few poor at present both at home and abroad, the oise insulation factor of individual layer wall can not meet the minimum sound insulation requirement of Separate Home wall, only can be used for overlapping internal partition wall.Even if increase Sound-proof material, too increase building operation difficulty.
