Abstract

The invention discloses a natural stone binder. The natural stone binder comprises, by weight, 50% of P.O42.5 general portland cement, 45% of first dry quartz sands, 3.2% of second dry quartz sands, 1.5% of re-dispersible latex powder, 0.1% of starch ether and 0.2% of lignocellulose. The natural stone binder with reasonable cost and stable performances, prepared through reasonably selecting the granularity of the dry quartz sands and the weight percentage of the re-dispersible latex powder, has the advantages of firm bonding, difficulty in slipping, high flatness, convenience and fastness in construction, reduction of the labor intensity, improvement of the working environment, and low and controllable cost.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a natural stone binder. Background technique [0002] Natural stone adhesive is used as a bonding material for the surface of natural stone blocks such as floors, walls, and roofs. When in use, the surface of stone blocks can be directly pasted on the base or can be pasted On the dry and hard mortar cushion, the existing stone binder has problems such as low tensile bond strength, poor weather resistance, easy efflorescence, poor slip resistance, and difficult to control the flatness. Contents of the invention [0003] In order to solve the problems of low tensile bonding strength and poor slip resistance of existing stone binders, the present invention discloses a natural stone binder. The composition and weight percentage of the natural stone binder are: P .O42.5 General-purpose Portland cement 50%, first dry quartz sand 45%, second dry quartz sand 3.2%, redispers...
