Technical field
The present invention relates to building coating quality testing field, particularly to the method for the performances such as a kind of mechanical stability detecting emulsion。
Background technology
Emulsion is a kind of colloid, and it is in the colloidal state of a kind of stable existence, but this state is easily broken, and it all can be destroyed by such as soda acid, temperature, Strong shear power, concentration etc.。
Emulsion intercalation method refers generally to mechanical stability, Calcium ion stability。Mechanical stability refers to the emulsion stability when standing mechanically actuated, because in preparing coating process, will be pumped up, stir and the operation such as spraying during application, and therefore emulsion and coating thereof to withstand mechanically actuated。Calcium ion stability refers to freeze thaw stability, refer to the stability of the emulsion chemical drugs to adding, because in preparing coating process, in order to play filling effect and reduce cost, generally adding the thing of inorganic salts, therefore emulsion and coating thereof to detect Calcium ion stability。
Existing detection method is first to be filtered with 200 mesh filter screens by sample；Then in blender, use 1500-3000 rotating speed, strong stirring 5-10 minute, then filter with 200 mesh filter screens, weigh the dry residue on filter screen；It is best for not having any residue。This detection method does not explicitly point out blade of stirrer, the specification of a mixing bowl and the collocation of specification ratio thereof；Also without considering that emulsion can be influenced by powder after being configured to coating or sand grinds the Strong shear power and heat that produce。
Along with people's living standard constantly improves, the color requirements of coating is also emerged in an endless stream, emulsion be made into coating after mechanical stability also increasingly paid attention to；Particularly true mineral varnish and texture coating, the sand ratio in its formula typically constitutes from 60% in whole formula, even more；During dispersion, the diameter of requirement dispersion cylinder is 1.5-2 times (otherwise not easily making true mineral varnish and texture coating dispersion) of dispersion impeller, is more easily generated heat, and this does not require nothing more than emulsion fine mechanical stability, also to have good thermostability；The performances such as the mechanical stability of emulsion are the important indicators that engineers component design considers, therefore in the urgent need to the detection method of the performances such as a kind of mechanical stability that can quickly detect emulsion。
Summary of the invention
In order to solve the problems referred to above existing for prior art, a kind of method that the invention provides mechanical stability detecting emulsion, the method is possible not only to detect quickly and easily the mechanical stability of emulsion, and can incidentally detect the calcium of emulsion from stability and thermostability。
Technical solution of the present invention is as follows:
A kind of method of the mechanical stability detecting emulsion, it is characterised in that: it includes the following step sequentially carried out:
1. first emulsion to be measured is placed in dispersion cylinder；
2. then open dispersion machine, turn speed to 700-900r/min, after dispersant, wetting agent, defoamer and triple superphosphate being sequentially added into dispersion cylinder under this rotating speed, improve dispersing speed to 2000-2500r/min, disperse 10-20min；
3. add coalescents after, continue dispersion 10-15min；
4. observe the system that obtains of dispersion, if system does not have gel, then the mechanical stability of emulsion to be measured, Calcium ion stability and heat-resist are described；If system gel, then the mechanical stability of emulsion to be measured, Calcium ion stability and poor heat resistance are described；
In above steps, the weight proportion of each detection raw material is as follows: emulsion 190-210 part to be measured, dispersant 5.0-6.0 part, wetting agent 1-1.5 part, defoamer 1.5-2.5 part, triple superphosphate 400-450 part, coalescents 15-20 part。
The Cleaning Principle of the present invention is as follows: when the present invention utilizes dispersion impeller, dispersion cylinder, triple superphosphate to destroy emulsion intercalation method under Strong shear power, adds coalescents；Make emulsion receive coalescents under unstability state, if system gel, emulsion mechanical stability and Calcium ion stability, poor heat resistance are described；If system does not have gel, emulsion mechanical stability and Calcium ion stability are described, heat-resist。
Compared to prior art, the invention have the advantages that the method for the performances such as the mechanical stability of detection emulsion of the present invention is possible not only to the mechanical stability of detection emulsion, and can incidentally detect the calcium of emulsion from stability and thermostability, further, it is also possible to assessment dispersant and wetting agent and emulsion whether that are joined。
