Description
Technical field
Invention is related to a kind of inorganic heat insulation wall.
Background technology
In recent years, China had constructed the external thermal insulation system of enormous amount, wherein based on organic insulation material, from building
Build and achieve certain achievement from the aspect of saving.But the fire of the thing followed in rapid succession has beaten alarm bell to people,
Thus Building Fire Protection, the fire safety problem of particularly external wall outer insulation are paid much attention to.In September, 2009, the Ministry of Public Security, house and city
The Ministry of Construction of township is in issue《Civil buildings outer heat preservation system and decoration of exterior wall fire prevention temporary provisions》([2009] No. 46).2011
March 14, the Fire-Fighting Bureau under the Ministry of Public Security issues again《On further clear and definite civil buildings insulation material fire supervision management about wanting
The notice asked》.Notice request " before new standard issue, performs as strict as possible《Civil buildings outer heat preservation system and decoration of exterior wall fire prevention are temporary
Professional etiquette is determined》(the logical word [2009] 46 of public affairs) Article 2 regulation, civil buildings heat insulating material for external use material of the combustibility for A levels
Material ".
The mandatory provisions of these files so that the use of organic insulation material is greatly constrained.Thus, the side of people one
Face begins look for, develops the insulation material that can reach inorganic non-ignitable performance requirement, and on the other hand, people are to the energy applied in the past
The external thermal insulation system for enough reaching A level incombustible materials carries out further development and application.In the previous case, outside rock cotton board
Wall outer heat preservation system technology is arisen at the historic moment, and is widely applied rapidly, occupies a certain amount of market share.In latter event
Under, the building heat-insulating mortar external thermal insulation system for having had certain application and the market share in the past obtains further
Using the market share occupied increases rapidly.
On January 20th, 2013, house and town and country construction portion issue《On carrying out State Council on strengthening and improvement disappears
The notice of the opinion of anti-work》, it is specified that " combustibility of civil buildings heat insulating material for external is preferably A levels, and not lower than B2 levels ".
Although combustibility reaches the insulation materials of B2 levels and is applied to wall face since so, due to many fire departments in the localities
Do not decontroled in terms of final acceptance of construction, it is thus possible to which reaching the non-ignitable external-wall heat-insulation material of A levels still has very big application
Market.

Cementing material of the cement as inorganic heat insulation mortar, its 28d intensity should be not less than 32.5MPa, i.e. strength grade not
32.5 grades should be less than.My company uses the 32.5 grade composite silicate cement that Tongling Conch Cement Co., Ltd produces, product
It is of fine quality good, dependable performance.
3 days compression strength of the cement reach 18.5MPa；Compression strength reaches 138.1MPa within 28 days；3 days rupture strengths
Reach 4.0MPa；Rupture strength reaches 7.4MPa within 28 days.
Redispersable latex powder is spiked into inorganic heat insulation mortar, boundary mortar, anticracking grout, can play two kinds of works
With first, the surfactant residued in latex powder can play strong water-reduction, because of the ratio of mud of reduction mortar
Improve intensity；Second, latex powder can make up the microdefect in Behavior of Hardened Cement Paste and improve the toughness and bond strength of mortar.Production
In use Shanxi Sanwei Group Co., Ltd. SWF-04 types latex powder (be used for produce anticracking grout and interface sand
Slurry) and SWF-05 types latex powder (being used to produce thermal insulation mortar), its technical performance is as shown in Table 1 and Table 2.
The technical performance of the three-dimensional company SWF-04 type latex powders of table 1
The technical performance of the three-dimensional company SWF-05 type latex powders of table 2
Certain technical economic benefit can be obtained using flyash.First, flyash can improve the intensity of product, energy
Enough improve the mineral structure in cement-based material, improve compactness.Flyash can also improve the workability of thermal insulation mortar, make
Fabulous workability is presented in mortar.Secondly, the cost of flyash is very low, even if I grade of commercial fly ashes of packing good, price
It is more much lower than the price of cement yuan one ton only more than 100, it may be substituted for part of cement.
The maximum performance advantage that flyash is applied in cement-based material also resides in its later stage hydrating capacity.This can either
The intensity of cement-based material is improved, and can enough improves the mineral structure in cement-based material, improves frost-proof test.Flyash
In the rear age of hydrated cementitious, start aquation under the excitation of calcium hydroxide caused by hydrated cementitious, due at this moment cement
Sufficient aquation has been carried out, in the structure there is a large amount of capillary porosities, the hydrated product of flyash being capable of blockage structure
In these capillary porosities, improve the density of flue structure.
Thus, it can increase Slurry transport using flyash in the production of inorganic building heat-insulating mortar, improve the sum of slurry
Yi Xing, the dry density of thermal insulation mortar is reduced, make that the structure of thermal insulation mortar is more closely knit, and intensity is higher.On the contrary, if not use
Flyash, but improve the workability of mortar mixture by increasing cement consumption, then it can increase the dry density of product, reduce
The thermal property of thermal insulation mortar.
The dry ash discharge in power plant is used in the present invention, product quality is I grade.Performance meets standard GB/T/T
1596—1991《Regulation for the flyash in cement and concrete》Requirement.
The middle flyash used is the commercial fly ashes of Mount Huang Xin Tai industrial and trading companies supply in the present invention, what supplier provided
Jiujiang utilization of fly ash Co., Ltd is 3.68% to the testing result of the flyash loss on ignition.
Expanded and vitrified small ball is a kind of new inorganic lightweight aggregate and heat-insulating material, its particle in irregular spherical, its
Inside is porous cavity structure, and appearance face closure, smooth, have light, adiabatic, fire prevention, high temperature resistant, it is ageing-resistant, absorb water
The low excellent properties of rate.Expanded and vitrified small ball is the main body insulation material of expanded and vitrified small ball inorganic heat insulation mortar, and its performance is straight
Connect the product quality for being related to expanded and vitrified small ball inorganic heat insulation mortar, including physical mechanics intensity, dry density and insulation
Performance.Thus, it should be noted that using quality product.
The expanded and vitrified small ball used in the present invention is the product of District, Xinyang Area, Henan Province Hua Xin building materials Co., Ltd, is using coal gas
The product of heat-supply type glass bead puffing furnace production.Its bulking process is reliable, and product quality is stable.The glass bead product belongs to
In the market mass ratio is preferable, and price is somewhat higher.The performance of the expanded and vitrified small ball is as shown in table 3.
The technical performance of the expanded and vitrified small ball of table 3
Opened and fed intake due to methyl.Polypropylene fibre is difficult to disperse, and special measure can be taken to handle when feeding intake, help its point
Dissipate.The quantity such as cellulose ether, flyash, polypropylene fibre, some additives and latex powder are small, it should when feeding intake and cement
Fork.
After cement and methyl cellulose ether, flyash, polypropylene fibre, additive, latex powder etc. are well mixed, input
Glass bead is uniformly mixed, and obtains finished product expanded and vitrified small ball inorganic heat insulation mortar.
Boundary mortar, the production process of anticracking grout are substantially similar.In process of production it should also be noted that first opening dust removal machine
Switch, carry out dedusting.
