Abstract
The invention discloses a ready-mixed mortar water-retention thixotropic agent and a preparation method thereof. The mortar comprises the components of, by mass: 20-40% of cellulose ether, 10-20% of a thickener, 8-15% of re-dispersible latex powder, 0-2% of a surfactant, and 40-50% of a thixotropic agent. The components with the specified mass percentages are uniformly mixed in a mixing machine, such that the ready-mixed mortar water-retention thixotropic agent is obtained. The ready-mixed mortar water-retention thixotropic agent has the characteristics of good water retention performance, cohesiveness, construction smoothness, and no VOC. When the agent is used in manual work mortar and machine-sprayed mortar, construction efficiency and project quality can be substantially improved.
Description
Technical field
The present invention relates to a kind of material of construction, specifically a kind of premixing mortar water conservation thixotropic agent and preparation method thereof, belongs to building material technical field.
Background technology
Along with the popularization of premixing mortar, the demand of grout additive also increases thereupon, and the water-holding agent of premixing mortar mainly be take densification powder and ether of cellulose as main at present, and the water retentivity of mortar that mixes densification powder is poor, intensity is low, can cause metope hollowing cracking; And there is the defect that application property is poor, intensity is low, cost is high in the mortar that mixes merely ether of cellulose.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of premixing mortar water conservation thixotropic agent and preparation method thereof, the feature with good water-retentivity, cohesiveness and construction smoothness and VOC free, in the middle of handwork mortar and machine sandblast slurry, significantly improve operating efficiency and construction quality.
To achieve these goals, the premixing mortar water conservation thixotropic agent that the present invention proposes be take ether of cellulose, thickening material, redispersable latex powder and thixotropic agent as main raw material, and the mass percent of its each component is as follows:
The present invention's ether of cellulose used is hydroxypropyl methyl cellulose ether or hydroxyethylmethyl-cellulose ether, and volume accounts for the 20-40% of total amount.
The present invention's thickening material used is starch ethers and properties-correcting agent, described thickening material is starch ethers and properties-correcting agent, its volume is the 7-13% that starch ethers accounts for total amount, properties-correcting agent accounts for the 3-7% of total amount, described starch ethers is one or both in hydroxyalkyl starch, carboxymethyl starch, cationic starch, guar gum ether, and properties-correcting agent is one or both in polyoxyethylene, polyvinyl alcohol.
The present invention's redispersable latex powder used is commercially available rubber powder, composition is one or more in ethene and vinyl acetate copolymer, vinyl acetate and tertiary ethylene carbonate multipolymer, acrylic acid ester copolymer, vinylbenzene and acrylate copolymer rubber powder, and volume accounts for the 8-15% of total amount.
The present invention's surfactant component used is alkyl sulfonates, alkylsurfuric acid salt, fatty acid salt, rosined soap class or triterpenoid saponin etc., and volume accounts for the 0-2% of total amount.
The present invention's thixotropic agent composition used is the layer silicate minerals such as modified alta-mud, montmorillonite or neusilin, accounts for the 40-50% of total amount.
The preparation method of this premixing mortar water conservation thixotropic agent is as follows: by massfraction, take respectively ether of cellulose, thickening material, redispersable latex powder, tensio-active agent and thixotropic agent, pour in stirrer and stir, obtain described premixing mortar water conservation thixotropic agent.
Compared with prior art, this premixing mortar water conservation thixotropic agent and preparation method thereof is to be that 20-40% ether of cellulose, 10-20% thickening material, 8-15% redispersable latex powder, 0-2% tensio-active agent and 40-50% thixotropic agent fully mix and obtain this premixing mortar water conservation thixotropic agent in mixer by mass percent, it has the feature of good water-retentivity, cohesiveness and construction smoothness and VOC free, in the middle of handwork mortar and machine sandblast slurry, operating efficiency and construction quality have been significantly improved.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.
