醇酸树脂是一类带有醇和酸官能团的树脂, 常用于油漆, 墨水, adhesive and other fields. Its basic structure is a linear or cross-linked polymer compound formed by condensation reaction of multiple alcohol and acid functional groups, which has good solubility, processability and chemical corrosion resistance. Alkyd resins are widely used in the field of coatings and can be applied in surface protection and decoration of metal, 木头, glass and other materials due to their excellent adhesion, 耐腐蚀性和耐化学性.

检测方法
The following is a detailed description of the testing method for the common performance indicators of the above alkyd resin:

Viscosity test: Measure the viscosity of alkyd resin solution by viscometer. For the test, the sample should be dissolved in the appropriate solvent, and the operation instructions should be followed to read the viscosity value.

Density detection: The density of alkyd resin samples is measured by densitometer. The sample should be fully stirred and vented before being poured into the measuring tube of the densitometer for reading.

Solid content detection: heat drying method is used to measure the solid content of alkyd resin. The sample is heated to a certain temperature so that the volatiles in it evaporate completely, and then the sample is weighed to calculate the solid content.

Drying time detection: measure the drying time of alkyd resin coating by drying oven. Apply the sample to the test plate and then place it in the drying oven to observe the drying time.

Chemical resistance test: Corrosion test is used to evaluate the chemical resistance of alkyd resin. The samples were immersed in different chemical reagents and then examined for changes in properties such as weight and appearance.

防水测试: Water immersion test was used to evaluate the water resistance of alkyd resin. The sample is immersed in water for a certain time, and then its weight, appearance and other performance changes are detected.

Temperature resistance test: Thermal stability test is used to evaluate the temperature resistance of alkyd resin. The sample is heated to a certain temperature and continued for a period of time, and then its appearance, weight and other performance changes are detected.

Uv resistance test: UV aging test is used to evaluate the UV resistance of alkyd resin. The sample was exposed to UV radiation for a certain period of time, and then its appearance, color difference and other performance changes were detected.

耐磨测试: Wear test is used to evaluate the wear resistance of alkyd resin. After wearing the sample for a certain number of times,

Test its weight, appearance and other performance changes.

Weather resistance test: weather aging test is used to evaluate the weather resistance of alkyd resin. The samples are exposed to specific climatic conditions for a certain period of time, and then their appearance, color difference and other performance changes are detected.

附着力测试: Peel test is used to evaluate the adhesion of alkyd resin. The sample is coated on the test plate and then peeled off by stretching, ETC。, and the adhesion index is finally evaluated.

Tensile strength and elongation at break testing: Tensile tests are used to evaluate the tensile properties of alkyd resins. The samples were made into certain samples and tested on the tensile testing machine, and finally the tensile strength and elongation at break and other indicators were obtained.

Hardness testing: Use a hardness tester to measure the hardness of alkyd resin. The sample is made into a sample according to the specified size, tested on the hardness tester, and finally the hardness value is obtained.
