Abstract
The present invention relates to instant and instantly dispersed latex powder and a manufacturing method thereof. The present invention adopts EVA emulsion and PAA emulsion as main materials and EDTA, cellulose ether or polyethylene alcohol or polyacrylamide, organic silicone emulsion, magnesium silicate, dolomite dust and triethanolamine as auxiliary materials; after the main materials and the auxiliary materials are stirred, mixed, atomized, dried, cooled, tested and packaged, the latex powder is obtained. The latex powder can be dissolved instantly and can be dispersed instantly and evenly in water, and the latex powder can become latex with raw liquor properties again. The latex powder can be made with a plurality of inorganic gelled materials, such as cement, hemihydrate gypsum, etc., into finished product dry mortar, such as polymer cement dry-mixed mortar, polymer plastering gypsum, etc., with special properties and uses. The latex powder which has stable quality, easy packaging, moisture-proof, frost protection, easy transportation, easy storage and no bacterium or microbe is suitable for the manufacture of polymer bonding mortar, covering mortar, a ceramic tile binder, elastic putty, self-leveling mortar plastering gypsum, etc. for the external insulation or the internal insulation of building external walls.
Description
Technical field
The present invention relates to a kind of instant fast dispersive latex powder and manufacture method thereof, relate to specifically a kind of can be in water dissolving rapidly, disperse uniformly rapidly, latex can also be formed again, the latex powder and the manufacture method thereof of cement characteristics can be improved with stoste performance.
Background technology
At present, the existing over one hundred year history of the scale operation of cement material and application, its as hard as flint has very high ultimate compression strength, its water is in harmonious proportion, and generates hydrated product, has the good hydraulicity, excellent in durability, and easy to use, but its extensibility is very low, and anti-permeability performance is poor, easily shrinkage cracking.
For improving impermeability, frost resistance and the thermotolerance of cement material, reduce or thoroughly stop cement material cracking problem, since the 1950's, some polymer emulsion was come out one after another, scientists is mixed polymer emulsion and is studied successful polymer cement mortar and polymer concrete in the cement successively, thereby cohesive strength, the cohesive strength of cement-based material have been strengthened, and make it have snappiness, improved tensile strength, deformability, ageing resistance, cohesiveness, wear resistance of cement material etc.
But, this employing polymer emulsion mixes and stirs the method for cement, there are many defectives, it can only matching while using, can not batch production scale operation, can not store and also be unfavorable for environmental protection and long-distance transportation, and on-the-spot prepared polymer cement material also lacks the monitoring means of science, its quality also is difficult to be protected.
