All various advantages such as this can drop, conducive to the development of building industrialization and housing industrialization.The structures such as prefabricated panel, floor, column
Interconnection technique between part is the key that assembled architecture, and the seam between each component how is effectively treated, connects between guarantee prefabricated components
The overall performance for connecing performance and structure is difficult point in the splicing of assembled architecture component.
The level and vertical abutment joint of assembled architecture outer wall plate are the weak links of waterproof.Joint treatment is most common at present
Mode has two classes: first is that carrying out the processing of pointing stuff up a crack using dry cement mortar, but due to the initial adhesive force of cement mortar
It is poor, effective connection, and the easy shrinkage cracking of ordinary cement cannot be formed between component, in turn result in the leakage of seam areas.Two
Be processing, such as sealing strip, band and gasket seal are sealed using macromolecule sizing sealing material abutment joint, but due to
The error that generates in component splicing, can bring difficulty to the installation of sizing sealing material, and such sealing material itself also intolerant to
Aging is also easy to produce deformation, falls off and leakage phenomenon occur after long-time service.
Meanwhile with the development of economy and society, people require higher and higher, the insulation of assembled architecture for environmental protection and energy saving
The factor that index also becomes architectural design, construction and must be taken into consideration when checking and accepting.Equally, the seam of prefabricated member is also its insulation
The weak link of performance.The waterproof of assembled architecture seam and insulation are usually separately construction at present, and construction is compared twice
It is complicated and limit its application to a certain extent.Therefore, it is necessary to novel waterproof insulation integrated technique be developed, together
It in process, that is, may achieve two technical needs of waterproof and insulation, be assembled to simplify construction cost, reduce difficulty of construction
Building level and the waterproof of longitudinal seam, insulation provide new solution.
107840609 A of patent CN discloses a kind of waterproof thermal insulation mortar, and the waterproof thermal insulation mortar is by cement, hard carbon
More than ten raw material such as sour calcium, redispersable latex powder are made, and have certain waterproofness and thermal and insulating performance.But due to original
The limitation of material and construction technology, the waterproof thermal insulation mortar still have and component initial adhesive force is poor, easy shrinkage cracking, waterproof
Performance is poor, the easy moisture absorption, the problems such as heat insulation effect is bad
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind to build for assembled
It builds seam waterproof and is insulated integrated super-hydrophobic particle and its preparation method and application, solve assembled architecture seam and easily seep
The problems such as water, poor heat insulation effect, primary construction can be thus achieved waterproof and two heat-insulated demands, significantly reduce construction work
Sequence improves construction efficiency, and its preparation and construction technology are simple, have boundless application prospect.
The purpose of the present invention can be achieved through the following technical solutions:
It includes particle cores that the present invention, which provides one kind and is insulated integrated super-hydrophobic particle for assembled architecture seam waterproof,
