Embodiment 1
[0030] The structure of the safety socket provided by the invention is as Figure 1~3 As shown, a cover plate 2 is provided on the top of the socket body 1, and the cover plate 2 and the socket body 1 are movably connected to each other through a rotating shaft 3 located on the upper edge of the socket body 1; figure 2 , under the socket body 1, a first protruding shaft 4 facing upwards is provided, a first collar 6 is provided under the inner side of the cover plate 2, a connecting rod 5 is sleeved in the first collar 6, and connected The upper end of the rod 5 is fixed with a first groove 7, and when the cover plate 2 is closed, the first groove 7 can be sleeved on the first protruding shaft 4; as image 3 , a second groove 8 is provided on one side of the socket body 1, the notch of the second groove 8 faces outward, and a second collar 9 is also arranged on the same side inside the cover plate 2, and the second collar 9 A fixed rod 10 is sleeved in the middle, and the fi...
Embodiment 2
[0033] In order to improve the flame retardancy of the plastic, the present invention also provides a method for preparing the flame retardant plastic on the cover plate 2 and the socket body 1, the steps are as follows:
[0034] Step 1. In parts by weight, take 20 parts of methyltriethoxysilane, add it to 400 parts of water, and perform hydrolysis under the action of 0.2 parts of formic acid as a hydrolysis catalyst. The hydrolysis reaction time is 2 hours, and the hydrolysis temperature is 3°C After the hydrolysis is completed, the temperature is raised to carry out the polymerization reaction, and after the reaction is completed, the vacuum distillation is carried out to obtain the silicone resin;
[0035] Step 2. Mix 20 parts of isophthalic acid and 20 parts of neopentyl glycol, heat up, and carry out condensation reaction under the protection of argon. The temperature of condensation reaction is 170°C. The acid value of the reaction system under the condition of terminatin...
