Description
Technical field：
The invention belongs to construction material production technical field more particularly to a kind of flooring heat insulating and sound insulating mortars.
Background technique：
The energy consumption mode of building is mainly heating and refrigeration.For heating, the northern area of China carries out concentration confession
Warm, the temperature difference between different residents is little.Therefore, building energy conservation level can be improved by improving exterior-wall heat insulation performance.And for
The southern area of individual heating, the requirement due to different residents to temperature is different, and floor gap is caused to generate the biggish temperature difference, heat
In floor gap transmitting, loss.For refrigeration, what China took is a point measure for family refrigeration.Although improving exterior-wall heat insulation level has
It still will cause the loss of the energy, waste conducive to the temperature difference of reduction energy consumption, but different floor gaps.Therefore, need to divide family floor into
Row isothermal holding.
Also, divide family floor as the building element for separating different residents, the quality of sound insulation property has neighborhood relationship
Particularly important influence.In general, the air-borne sound oise insulation factor of the reinforced concrete floor of 120mm thickness is 48~50dB.It adds
Surface material on floor, this will further increase the air-borne sound sound insulation property of flooring, can be good at meeting《It is civilian to build
Build sound insulation design standard》Related request in GBJ 118-1988.But the shock sound pressure level of floor is usually in 80dB or more,
It is not by far up to the mark.Therefore, the emphasis of point family floor sound insulation is isolation strike note.
Therefore, it is necessary to develop a kind of suitable for a point material for family floor heat insulating and sound insulating processing.And flooring heat insulating and sound insulating
Mortar has both heat preservation, sound insulation function, and easy for construction, suitable for dividing the heat insulating and sound insulating of family floor to handle.But it is presently used
Flooring heat insulating and sound insulating mortar cannot effectively have both two kinds of functions of heat preservation and sound insulation, this is primarily due to heat insulating and sound insulating function used
The reason of energy component.But aerosil has nanoporous network structure, can effectively inhibit solid-state heat transfer gentle
Body heat transfer, has excellent insulative properties.And gaseous state decentralized medium is full of in its network pore, the vibration for hitting generation can draw
The vibration friction of its inner gaseous medium is played, energy when Vibration propagation is consumed, plays the role of vibration and noise reducing.But currently, still
There is not the relevant report being applied to aerosil in flooring heat insulating and sound insulating mortar.
Summary of the invention
The object of the present invention is to provide a kind of flooring heat insulating and sound insulating mortar, which can be effectively improved point family floor
Heat preservation and sound insulation property, and it is easy for construction.
To achieve the above object, the present invention provides a kind of flooring heat insulating and sound insulating mortar, which is characterized in that the flooring
Heat insulating and sound insulating mortar includes the raw material of following parts by weight：180-280 parts of cement；20-50 parts of floating bead；Waste rubber powder 50-100
Part；1.5-4 parts of aerosil；2-4 parts of rubber powder；1.5-3 parts of cellulose ether；1-1.5 parts of fiber；1.8-3 parts of water-reducing agent.
Further, the cement is the portland cement or ordinary portland cement that label is not less than 42.5.
Further, the floating bead is the spheric granules of smooth in appearance, bulk density 350kg/m3Left and right, partial size 40
~80 mesh, hollow ball form quotient are greater than or equal to 95%.
Further, the waste rubber powder is waste tire gained through processing, and partial size is 0.6~2.5mm.
Further, the porosity of the aerosil is greater than 85%, and thermal coefficient is less than 0.03W/ (mK),
Partial size is 1~5mm.
Further, the aerosil is silane coupler modified aerosil, specific modification side
Method includes the following steps：1) silane coupling agent that quality is aerosil quality 1~2% is dissolved in dehydrated alcohol, silicon
The mass fraction of alkane coupling agent solution is 5~20%；2) aerosil is added to the silane coupled of step 1) preparation
In the solution of agent, 10~30min is stirred；3) the resulting aerosil drying of step 2) is changed to get silane coupling agent
Property aerosil.
Further, the rubber powder is redispersable latex powder, and the cellulose ether is hydroxypropyl methyl cellulose ether, institute
Stating water-reducing agent is powdered high-efficiency water-reducing agent of poly-carboxylic acid, and the fiber is the polypropylene fibre that is chopped.
The present invention is overcome poly- using aerosil, waste rubber powder, floating bead as heat insulating and sound insulating function ingredients
Disadvantage of the benzene particle as heat insulating and sound insulating function ingredients fire protecting performance difference.Under the premise of guaranteeing the fire protecting performance of mortar, effectively
Ground improves the thermal insulation property and strike note sound insulation property of mortar.Meanwhile using silane coupler modified aerosil,
The interfacial adhesion that aerogel particle and cement matrix can be effectively improved improves the intensity of mortar.Also, by silane coupling agent
Modified silica aerogel particles are dried to powder, so that heat insulating and sound insulating mortar is one-component, scene is added water and stirred i.e.
It can construct, it is easy to operate, it is high-efficient.
