Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Comparative example 1:
the invention provides a nano composite coating and a preparation method thereof, and the nano composite rubber provided by the invention comprises the following components: 100 parts of acrylic ester and 25 parts of graphene (the number of layers is less than or equal to 5). The nano composite coating is prepared by the following steps:
1) adding graphene (the number of layers is less than or equal to 5) into 100 parts by mass of acetone at 35 ℃ at 4000 r/min, and stirring for 30 min to obtain a nano filler;
2) adding acrylate into 100 parts by mass of acetone at 35 ℃ at 4000 r/min, and stirring for 1 h to obtain an acrylate solution;
3) mixing the solutions prepared in 1) and 2) according to a volume ratio of 1:4, and stirring for 8 hours at 42 ℃ and 4500 r/min to prepare the nano composite coating liquid.
As shown in figure 2, the friction coefficient of the windshield wiper coated with the nano composite coating is 0.3-0.5, which is slightly reduced compared with that of the windshield wiper which is not modified by the nano filler and is 0.4-0.6. After 10 million wear tests, the coating survived a small amount.
Example 1:
referring to fig. 1, a nanocomposite coating and a method for preparing the same, the nanocomposite coating provided by the invention comprises the following components: 100 parts of acrylic ester and 25 parts of graphene (the number of layers is less than or equal to 5) of P13. The nano composite rubber is prepared by the following steps:
1) adding P13 and graphene (the number of layers is less than or equal to 5) into 100 parts by mass of acetone according to the mass ratio of 1:10 at 35 ℃ at 4000 r/min, and stirring for 30 min to obtain a nano filler;
2) adding acrylate into 100 parts by mass of acetone at 35 ℃ at 4000 r/min, and stirring for 1 h to obtain an acrylate solution;
3) mixing the solutions prepared in 1) and 2) according to a volume ratio of 1:4, and stirring for 8 hours at 42 ℃ and 4500 r/min to prepare the nano composite coating liquid.
As shown in figure 3, the friction coefficient of the windshield wiper coated by the nano composite coating is 0.3-0.5, which is greatly reduced compared with the friction coefficient of the windshield wiper without the nano filler modification treatment. After 10 million wear tests, the coating still remained largely.
