Abstract

The emulsoid powder is produced with EVA emulsion and PAA emulsion as main material and EDTA, cellulose ether or PVA or polyacrylamide, organic silica emuilsion, magnesium silicate, dolomite powder and triethanolamine as supplementary material, and through stirring, mixing, atomizing to dry, cooling and other steps. It may be dissolved in water and dispersed fast to form homogeneous emulsion. It may be mixed with several kinds of binding material, such as cement, hemihydratd gypsum, etc. to form mixture with specific performance and use, such as dry mixed polymer-cement mortar, rendering polymer-gypsum, etc. for building.

Description

technical field [0001] The present invention relates to a kind of instant dispersible latex powder and its manufacturing method, in particular to a kind of latex which can be quickly dissolved in water, can be quickly and evenly dispersed, and can also re-form latex with stock solution properties, and can improve cement properties powder and its production method. Background technique [0002] At present, the large-scale production and application of cement materials has a history of more than 100 years. It is as hard as stone and has high compressive strength. Convenient, but it has low extensibility, poor impermeability, and easy shrinkage and cracking. [0003] In order to improve the impermeability, frost resistance and heat resistance of cement materials, reduce or completely eliminate the cracking of cement materials, since some polymer emulsions came out one after another in the 1950s, scientists have mixed polymer emulsions into cement Succe...
