Description
Technical field
The present invention relates to technical field of construction and decoration materials, more specifically, it relates to a kind of sound insulation terrace mortar and its
Preparation method and sound insulation method for constructing terrace.
Background technique
Heat-insulation system is of great significance for building energy conservation noise reduction.Routine building heat-insulation system is according to using thermal insulation material
Difference, be broadly divided into following two major classes:
One kind is paving heat preservation plate material, as extruded polystyrene foamed plastics (extruded sheet), molding type polystyrene foam are moulded
Expect (regular-type foam plate), hard-foam polyurethane insulation board, mineral wool (rock wool), foam glass, phenolic resin plate etc..In the prior art,
Authorization Notice No. is that CN207419940U Chinese patent discloses the wear-resisting decoration terrace system of sound-insulating, and what is used is to squeeze
Mould the mode that styrofoam carries out heat preservation and soundproof as heat preservation and soundproof plate.But this kind of terrace heat-insulation system includes multilayered structure,
Not only construction efficiency is low, the period is long for main successively construction, and after constructing terrace since permanent pressure-bearing easily causes between layers of material
Be bubbled, crack etc., useful life longevity is poor and there are problems that can only carry out entirety to terrace if being bubbled or cracking overhauls.
It is another kind of, it is filling thermal insulation material, as sprayed rigid foam polyurethane, foam concrete (foam mortar), lightweight aggregate are protected
Warm concrete (haydite concrete etc.), inorganic heat insulation mortar (kervit microbead insulated sand slurry), polyphenyl particle heat-insulating mortar, expansion are precious
Pearl rock thermal insulation mortar etc., the considerations of for convenience for construction, cost, service performance etc., and it is most commonly seen with thermal insulation mortar,
Such as gypsum base thermal insulation mortar.
Gypsum is a kind of mineral from a wealth of sources, and the microcellular structure and thermal dehydration of gypsum and its product are allowed to have excellent
Good sound insulation, heat-insulated and fire protecting performance are the preferred materials for making building thermal insulation material.Gypsum due to its crystal structure characteristic,
Loose porous shape structure is presented in plastering, and water absorption rate is larger, and generally full water intensity only has 1/3 of dry strength or so, also limits
Its use.So most gypsum is used to produce plasterboard, gypsum block, brushing gypsum etc., for making terrace heat preservation
The also mostly of material are existed in the form of Self-leveling gypsum base mortar.Such as in the prior art CN108863275A,
It is the gravity flowing levelling mortar configured using gypsum as raw material disclosed in the patent documents such as CN106747173A, CN105272104B.
However, terrace is due to needing permanent load-bearing and tolerance pedestrian to walk abrasion etc., in addition to heat preservation and soundproof performance, it is also necessary to
With certain intensity.Conventional gypsum base gravity flow self-leveling floor mortar construction thickness is usually the aglite of 3-5mm, use
The mostly not high haydite of intensity, insulating pearlite etc. so that its intensity is not enough to adaptively plateau length time load-bearing and resistance to frayed
Requirement, thus can only as the surface layer of terrace adorn or as the auxiliary heat preservation and soundproof being used cooperatively with other thermal insulation materials
Means.
Therefore, how to research and develop one kind can be used as main material for the construction of terrace thermal insulation sound-proof system, easy and resistance to compression of constructing
The high gypsum base terrace mortar of intensity is problem to be solved in the industry.

It when warm system construction, directly scratches or sprays, readily and efficiently, the integraty of mortar is good after solidification for construction, and there is no protect
The problems such as easy hollowing such as warm plate, cracking, and do not interfere to apply in finish coats such as mortar surface layer paving floor tile, gypsum self-levelings
Work.By embodiment 4 and the comparison of the experimental data of reference examples 1-2, it is found that using β gypsum instead, mortar is anti-with configuring sound insulation of the invention
Compressive Strength is unable to satisfy requirement；Other general inorganic lightweight aggregates are used instead, as expanded perlite is also unable to reach resistance to compression of the invention
Grade.
Above-mentioned specific embodiment is only explanation of the invention, is not limitation of the present invention, art technology
Personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as
All by the protection of Patent Law in scope of the presently claimed invention.
