Abstract
The invention relates to machine-made dry-mixed plaster mortar suitable for mechanized spraying. The mortar is composed of the components of, by mass, 0-60% of limestone, 0-60% of limestone tailing, 0-28% of yellow sand, 9-25% of cement, and balance of an additive. The limestone and the limestone tailing are not simultaneously 0. The additive is a mixture of hydroxypropyl methyl cellulose ether, starch ether, re-dispersible latex powder and a thixotropic lubricant. According to the invention, through changing the component ratio of common plaster mortar, and with the additive and thickening agent with special performances, the problems of incapability to adapt to mechanized spraying caused by high angularity, poor fluidity, and high seepage rate of machine-made sand are solved. The mortar is a clean, energy-saving, and highly efficient representative in construction.
Description
Technical field
The present invention relates to a kind of dry-mixed plastering mortar, particularly relate to a kind of Machine-made Sand dry-mixed plastering mortar that is applicable to automatic arc spraying, belong to building material field.
Background technology
Machine-made Sand is by Mechanical Crushing, screening is made, particle diameter is less than the rock particles of 4.75mm, compare with natural sand, the Machine-made Sand material source is abundant fixing, be easy to control material quality, but it is multi-angular because existing, surface irregularity and easily produce in process of production the defectives such as stone flour and can't substitute in the production that natural sand is applicable to mortar comprehensively, so there is poor fluidity in the dry-mixed plastering mortar take Machine-made Sand as raw material production, rate high defective in Qinshui can not satisfy the requirement of mechanized construction, therefore, a kind of Machine-made Sand dry-mixed plastering mortar that is applicable to automatic arc spraying of exploitation is one of main task of those skilled in the art present stage.The present invention produces thus.
Summary of the invention
For solving the technical problem of prior art, the purpose of this invention is to provide a kind of Machine-made Sand dry-mixed plastering mortar that is applicable to automatic arc spraying, by changing the system component proportioning of common motar, settlement mechanism sand profile is multi-angular, poor fluidity, the high problem that can't adapt to automatic arc spraying of Qinshui rate.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of Machine-made Sand dry-mixed plastering mortar that is applicable to automatic arc spraying, composed of the following components by mass percentage:
Wingdale 0%-60%
Limestone tailing 0%-60%
Yellow ground 0%-28%
Cement 9%-25%
Admixture with surplus.
Preferably, described Wingdale and limestone tailing are not 0% simultaneously.
Described admixture is the mixture of hydroxypropyl methyl cellulose ether, redispersable latex powder, starch ethers and thixotroping lubricant.
The mass percent of described hydroxypropyl methyl cellulose ether, redispersable latex powder, starch ethers and thixotroping lubricant is hydroxypropyl methyl cellulose ether: redispersable latex powder: starch ethers: thixotroping lubricant=2:30:1:1.
The present invention is applicable to the Machine-made Sand dry-mixed plastering mortar of automatic arc spraying, by changing the system component proportioning of common motar, and use special property additive and viscosifying agent, solved because multi-angular, the poor fluidity of Machine-made Sand profile, the high problem that can't adapt to automatic arc spraying of Qinshui rate, be that building operation cleans, one of energy-saving, high efficiency representative.
Embodiment
The present invention is further illustrated below in conjunction with specific embodiment, but protection scope of the present invention is not limited to this.
