Description
Technical field
The invention belongs to a kind of building ground floor material, relates particularly to a kind of warm-land cushion course with thermal and insulating performance
Gypsum based self-leveling mortar.
Background technology
Japan has had ten in the basic research for having begun to gypsum-based self-leveling material in 1972, to Japan in 1979
The gypsum-based self-leveling material of a variety of brands, the 1980s, Anglo-American Law Russia started the research and development of gypsum based self-leveling, arrived
German dry-mixed mortar has taken up an area the 16.4% of terrace material within 2001.
Common gravity flow self-leveling floor material has three kinds both at home and abroad：1. cement-based self-leveling material；2. epoxy resin flows automatically
Flat material；3. gypsum based self-leveling mortar.Wherein cement-based self-leveling and epoxies self-leveling material have had at home at present
Fairly large application.But because cement-based self-leveling material has larger shrinkage, it can not typically be used as thickness at present
The ground of the larger standard width of a room in an old-style house of terrace or primary concreting of layer, epoxy resin self-leveling material are typically used as the surface layer of thin layer
Terrace uses.
It is late 1980s that China, which starts to research and develop gypsum based self-leveling, in recent years mostly using building gypsum plaster or
Anhydrite ensures to reach corresponding performance, causes gypsum based self-leveling as raw material by introducing substantial amounts of chemical addition agent
Material cost it is very high, and performance is not often very stable, so market acceptance level is not high.
Patent is concentrated mainly on the following aspects in terms of domestic gypsum based self-leveling mortar at present：1. utilize plaster of Paris
Powder and substantial amounts of cement are compounded, and then add certain chemical addition agent, and its patent represented has Fujian Construction Building Materials section
A kind of water desulfurized gypsum base surfacing self-leveling floor mortar of β types half of skill development corporation, Ltd., application number 201610348686.2.2. profit
Alpha type high-strength gypsum powder is prepared with desulfurated plaster or prepare alpha type high-strength gypsum powder using ardealite, then using preparing
Alpha type high-strength gypsum powder configures gypsum based self-leveling mortar, wherein more representational have the rising sun religion of Nanjing University of Technology Lee east
A kind of composite gypsum based self-leveling mortar and preparation method awarded, application number：201610882329.4 with Wuhan University of Technology horse
Protect the α high strength gypsums based self-leveling material prepared using ardealite and production technology of state professor, application publication number：CN
103288410 A.3. in the anhydrite class gypsum based self-leveling mortar that certain exciting agent configures, its generation, are added using natural anhydrite
Table has a kind of natural anhydrite gravity flow flat crack resistant mortars of Zhang Xuejian, application number：201610103519.1.
The general gypsum based self-leveling mortar using building gypsum plaster configuration tends not to meet existing industry JC/T
1023-2007 standard requirement.And the gypsum based self-leveling mortar of anhydrite configuration is used, anhydrite needs alkali-activated carbonatite just to have glue
Solidifying activity, hydration rate is slower, plus limitation of the current country to the exploitation of natural gypsum ore deposit, so the gypsum base of anhydrite configuration
Gravity flowing levelling mortar can not be promoted well.So it is current master to configure gypsum based self-leveling mortar using alpha type high-strength gypsum
Stream.The alpha type high-strength gypsum powder common intensity better performances prepared using desulfurated plaster, but its color is yellow, is configured to sand
Also it is in yellow after slurry hydration and hardening, traction is not high.And ardealite prepares alpha type high-strength gypsum, if later stage powder is handled
Imperfection, faintly acid is often presented after its aquation, so has an impact to concrete base layer.
The chemical gypsum of chlorine industry by-product is compared with compared to other kinds of industry by-product gypsum, its calcium sulphate dihydrate
Content be up to 99%, the alpha type high-strength gypsum powder intensity prepared using Dynamic Hydrothermal method using chlorine industry by-product gypsum
Performance is good, and whiteness is up to 85, and adhesive property is also closer to the high-quality natural gypsum.
Do not possess thermal and insulating performance already in the case of the less ratio of water to material of gypsum based self-leveling mortar, it is specific by introducing
Component makes the gypsum based self-leveling mortar performance with insulation again, into the hot topic studied instantly.
The content of the invention
For in place of above-mentioned the deficiencies in the prior art, the present invention solve the problems, such as be：There is provided one kind has insulation, disappears
The high gypsum based self-leveling mortar of sound, intensity and preparation method.
To solve the above problems, the technical scheme that the present invention takes is as follows：
A kind of warm-land cushion course gypsum based self-leveling mortar with thermal and insulating performance, include the group of following parts by weight
