And (3) performance detection:
firstly, detecting mechanical property
The mechanical properties of the glass fiber reinforced plastic products of examples 1 to 3 were measured, and the measurement results are shown in table 1:
TABLE 1
Detecting items Example 1 Example 2 Example 3 Basis of detection
Tensile strength MPa 120 122.28 123.42 GB/T1447-2005
Bending strength MPa 242 249.40 250.45 GB/T1449-2005
Density g/cm3 1.55 1.59 1.60 GB/T1463-2005
Hardness HBa 40 40.6 40.7 GB/T3854-2005
The above tests show that the glass fiber reinforced plastic product of the invention has good pearly luster, and simultaneously, the mechanical properties such as strength, hardness and the like are not affected.
Secondly, detecting the aging resistance
The glass fiber reinforced plastic products obtained from the above examples 1-3 were tested for their aging resistance (according to GB/T14552-2008), which simulates damage caused by solar uv light, the materials were tested for aging resistance by exposing them to controlled high temperature light, uv lamps were used to simulate the radiation of sunlight, condensation and water sprays were used to simulate dew and rain, and only days or weeks were required for uv irradiation equipment to simulate damage, including discoloration and color changes, that would occur outdoors today over a period of months or even years. For example, the total radiation intensity is 1120W/m2At this time, the irradiance value measured at 340nm was 0.68, which we can deduce to be 0.68W/m at the set value2340nm, corresponding to 6.55 times the outdoor irradiance. However, UV aging is closely related to temperature, and with reference to the guangzhou annual average temperature of 21.8 degrees, the empirical assessment is that the aging effect is enhanced by about 1.5 times when the temperature is raised by 1 time, so that at a set temperature of 60 degrees, there are 60/21.8 x 1.5 x 6.55-27 days, i.e.: a1 day UV test was performed, which corresponds to an outdoor aging effect of 27 days.
The test conditions of examples 1 to 3 are shown in the following Table 2, and the test results are shown in the following tables 3 to 5, respectively:
