What properties should be tested for phenylpropanoid emulsion? How to detect?
Phenylpropanoid emulsion is a polymer emulsion, the main component is phenylpropanoid, it is obtained by free radical polymerization of phenylpropanoid monomer emulsion. Phenylacrylic emulsion can be used to prepare various polymer materials, such as coatings, adhesives, paper coatings, asphalt modifiers, etc., with high durability, chemical resistance, anti-ultraviolet performance and other advantages, so it has been widely used in construction, automobile, textile, electronics and other fields.
Detection performance
The following are the common performance parameters that need to be tested for phenylpropane-acrylic emulsion and their brief descriptions, as detailed in the following table:
| Performance parameters | A brief description |
|---|---|
| Solid content | Nonvolatile components in the paint as a percentage of the total weight |

Detection method
The following is a detailed description of the test method for the common performance parameters to be tested for phenylpropanoid emulsions:
Solid content: The coating sample was dried to a constant weight at about 105 ° C, and the ratio of the mass of non-volatile substances to the total sample mass was calculated.
Viscosity: Use equipment such as rotational viscometer or dioptometer to measure the viscosity of the paint.
Particle size distribution: Particle size analyzer was used to measure the size distribution of particles in the phenylpropanoid emulsion.
pH value: Use PH meter and other equipment to measure the pH of the paint to evaluate the stability and performance of the paint.
Adhesion: Use tensile testing machine, shear testing machine and other equipment to measure the adhesion of the coating and the substrate surface.

Durability: evaluate the weather resistance, wear resistance and chemical resistance of the coating by simulating the exposure and wear tests in the actual use environment.
Emulsion stability: The emulsion stability of the coating is evaluated by analyzing the stability and dispersion of the phenylpropane-acrylic emulsion during storage, transportation and use.
North and South Tide remind you: different performance parameters may require different test methods and equipment, and there may be some industry standards and specifications, for the performance test of phenylpropane emulsion, you should also choose the corresponding test methods and standards according to the actual needs. At the same time, the test conditions and standardized operations need to be strictly controlled during the experiment to ensure the accuracy and reliability of the test.
