Summary of the invention
Technical problem to be solved by this invention is to provide a kind of heat preserving and insulating material.
A kind of heat preserving and insulating material, comprises the component of following weight parts: ordinary Portland cement 20-30 part, diatomite 40-60 part, negative ion powder 5-15 part for building, urea-formaldehyde resin 10-20 part, basalt fibre 1-3 part, sodium lauryl sulphate 0.2-0.8 part.
Preferably, described negative ion powder for building is made up of following weight parts raw material: 70 parts, tourmalinite, Neodymium trioxide 10-20 part, terbium peroxide 10-20 part.
Neodymium trioxide, Chinese another name: neodymium sesquioxide, CAS:1313-97-9.Terbium peroxide, CAS:12037-01-3.
Each raw material is mixed, pulverizes, described negative ion powder for building can be obtained.Again ordinary Portland cement, diatomite, negative ion powder for building, urea-formaldehyde resin, basalt fibre and sodium lauryl sulphate are uniformly mixed, described heat preserving and insulating material can be obtained.
Heat preserving and insulating material good effect of heat insulation of the present invention also can lasting anion releasing.
Embodiment
Below in conjunction with embodiments of the invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.
Take each raw material by the corresponding each embodiment of table 1 or comparative example data respectively, mix, pulverize, grinding, Control granularity D50≤0.5 micron, can obtain described heat preserving and insulating material.The tourmaline powder that tourmalinite selects Shijiazhuang Tourmaline mineral products company limited to produce.The urea-formaldehyde resin powder that urea-formaldehyde resin selects Langfang Sen Bang Chemical Co., Ltd. to produce.

Test case:
Get heat preserving and insulating material that 1000 grams of the present invention obtain to be placed in watertight chest and evenly to spread out, airtight 24 hours, the AIC-1000 anionic textiles instrument produced with Alphalab company of the U.S. detected once every 1 hour, get 20 data at every turn, try to achieve the mean value of each data as final detection result, test data is in table 2.

Comparing embodiment 1 and embodiment 2-3, tourmalinite and Neodymium trioxide and terbium peroxide composite, successful is better than tourmalinite and Neodymium trioxide is composite or tourmalinite and terbium peroxide composite.
As the common practise of this area, nano titanium oxide, cerium dioxide, lanthanum trioxide, oxidation are wrong, Neodymium trioxide respectively with tourmalinite compound, negative aeroion tells on as the strongest with the compound of cerium dioxide, terbium peroxide, lanthanum trioxide effect are general, and Neodymium trioxide, titanium oxide reduce the air-anion concentration that tourmalinite produces on the contrary.But the present invention finds unexpectedly, comparing embodiment 1 and comparative example 1, adopt tourmalinite and Neodymium trioxide and terbium peroxide composite, effect is better than tourmalinite and cerium dioxide is composite.
Table 3: heat preserving and insulating material performance test table
Basalt fibre, be basalt building stones after 1450-1500 DEG C of melting, by the continuous fibre of platinum rhodium bushing high speed pulling.Be similar to glass fibre, its performance is between high strength S glass fibre and alkali-free E glass fibre, and the color of pure natural basalt fibre is generally brown, and some is like golden.
Basalt fibre is a kind of emerging novel inorganic environment-friendly and green high performance fibre material, the basalt building stones that it is made up of oxide compounds such as silicon-dioxide, aluminum oxide, calcium oxide, ferric oxide and titanium dioxide after high-temperature fusion, by bushing Defect.Basalt continuous fiber is good stability not only, but also has electrical insulating property, anticorrosive, flame resistant, the multiple excellent properties such as high temperature resistant.In addition, the waste that the production technique of basalt fibre produces is few, and environmental pollution is little, can directly proceed in ecotope after product abandonment, without any harm, because of but a kind of genuine green, environment-friendly materials.
Above-described embodiment, is interpreted as only being not used in for illustration of the present invention limiting the scope of the invention.After the content of having read the present invention's record, those skilled in the art can make various changes or modifications the present invention, and these equivalence changes and modification fall into the scope of the claims in the present invention equally.
