The surface hardness of the specimen was measured at 25 ° C for 1 hour, and the measured hardness was calculated by pressing it for 5 seconds. After 10 measurements, the mean value was calculated.
실시예 1 내지 실시예 3 및 비교예 1 내지 비교예 3의 실험결과는 아래의 표 1과 같다.The experimental results of Examples 1 to 3 and Comparative Examples 1 to 3 are shown in Table 1 below.
실험결과 실시예 1 내지 실시예 3의 마찰계수는 안경테용 첨가제를 넣지 않은 비교예 1과 비교하여 확연히 차이나는 마찰계수를 확인할 수 있었다. 이에 따라 안경테용 첨가제는 마찰저감효과가 있음을 확인할 수 있었으며, 상기 안경테용 첨가제를 첨가하더라도 안경테의 표면경도는 비교예 1과 큰 차이점이 없음을 확인할 수 있다.
Experimental results The frictional coefficients of Examples 1 to 3 were significantly different from those of Comparative Example 1 in which no additive for eyeglass frames was added. As a result, it was confirmed that the additive for eyeglass frames had an effect of reducing friction, and even if the additive for eyeglass frames is added, the surface hardness of the eyeglass frame is not greatly different from Comparative Example 1.
