Description
Technical Field
The invention relates to the technical field of building materials, in particular to a floor surface heat-preservation self-leveling system and a manufacturing method thereof.
background
The self-leveling mortar has excellent workability, can save labor force and improve construction efficiency, and is widely applied to building decoration projects. The self-leveling mortar for ground is a building ground self-leveling material which is compounded by using inorganic cementing material or organic material as base material, aggregate and various additives. The self-leveling mortar comprises inorganic self-leveling mortar and organic self-leveling mortar, and the inorganic self-leveling mortar further comprises cement self-leveling anti-crack mortar and gypsum-based self-leveling mortar. The self-leveling mortar has the greatest characteristic of good fluidity, and can freely flow to form a horizontal plane under the action of self weight and self expansion stress, so that the ground can be accurately leveled in a large area in a short time, and great help is brought to the application of some engineering materials.
The gypsum-based self-leveling mortar is a ground self-leveling material which takes gypsum as a base material and is supplemented with aggregate, other cementing materials and additives, and has the advantages of high construction speed, short construction period, simple process, good heat-insulating and fireproof performances, warm and comfortable foot feel and the like. The gypsum base material for the gypsum-based self-leveling mortar mainly comprises alpha high-strength gypsum, beta gypsum and the like, and can be prepared by calcining natural gypsum, desulfurized gypsum and phosphogypsum. At present, the gypsum-based self-leveling mortar prepared by using alpha high-strength gypsum as a base material has better strength, the oven-dry breaking strength can reach 10MPa, and the oven-dry compressive strength can reach 29 MPa. However, since the gypsum-based self-leveling mortar is an air-hardening cementing material, the strength of the gypsum-based self-leveling mortar is far from that of cement self-leveling anti-cracking mortar, and therefore, the problem that the improvement of the strength of the gypsum-based self-leveling mortar is urgently needed to be solved is solved. When the self-leveling mortar is used as a terrace material, the surface of the self-leveling mortar is a structure which directly bears the abrasion of ground traffic. The thickness of the self-leveling mortar is relatively thin, and under the condition that the ground base layer is solid, the bearing acting force is mainly concentrated on the surface. The traditional phosphogypsum-based self-leveling material at present also has the problem that the flow property and the strength can not be further improved.
