Embodiment Construction

[0036] Applying the method of the present invention to predict the optical properties of PC materials in Xinjiang Turpan, U.S. Phoenix City and Xinjiang Ruoqiang, the specific steps are as follows:

[0037] (1) Prepare PC samples, prepare PC raw materials into color plates with a size of 60mm×80mm×3mm by injection molding method; test the yellowness index in the optical properties of the samples before carrying out the test, test 3 samples, and take the results many times The arithmetic mean of the test is recorded as the initial performance value of the sample, and the initial yellowness index of the PC material is 1.59;

[0038] (2) The natural aging test of PC materials was carried out in Turpan, Xinjiang, and the annual solar radiation in Turpan (I 1 ) and annual mean thermodynamic temperature (T 1 ), and get the following result:

[0039] I 1 =6993.08(MJ / m 2 )

[0040] T 1 =16.71(℃)+273.15=289.86(K)

[0041] After a 3-year natural aging test, the yellowness index o...

Abstract

The invention discloses a prediction method of optical performance of a polycarbonate material in a dry and hot environment. The method comprises the following two parts of 1, carrying out a natural aging test on a PS material in a certain dry and hot environment; and 2, calculating the optical performance of the PC material at other dry and hot places. The method is used for predicting the optical performance of the polycarbonate material in the dry and hot environment, the natural aging test is performed on the PC material at the certain dry and hot place, and the optical performance of thePC material after natural aging at other dry and hot places is speculated according to a test result.

Description

technical field [0001] The present invention relates to a method for predicting the optical properties of polymer materials, specifically a method for predicting the optical properties of polycarbonate materials in a dry heat environment. The polycarbonate material is subjected to a natural aging test at a site in a dry heat environment. Using known polycarbonate optical property data and environmental condition data to predict the optical properties of polycarbonate anywhere in a dry heat environment. Background technique [0002] As an important engineering plastic, polycarbonate (PC) is widely used in many industries such as automobile, electronics, and electrical appliances, and has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. Therefore, the research on its aging behavior has also attracted people's attention. [0003] At present, in the process of studying the natural environment weather resistance of PC mate...
