FIG. 1 is a process flow diagram for preparing acrylate waterproof coating.
Detailed Description
All the components used in the invention are commercially available except that the polyaniline nanofibers are prepared by themselves. The present invention will be described in further detail with reference to fig. 1.
The first embodiment is as follows:
the specific process for preparing the acrylate waterproof coating comprises the following steps:
step 1: preparing polyaniline nano-fibers: 5kg of aniline monomer and 25kg of ammonium persulfate are dissolved in 400kg of 50% acetic acid to obtain a premix; carrying out ultrasonic treatment on the premix at 20 ℃ for 30min, and standing for 3h to obtain polyaniline nanofiber dispersion liquid; filtering and washing the polyaniline nanofiber dispersion solution, and freeze-drying to obtain polyaniline nanofibers;
step 2: weighing 12kg of polyaniline nano-fiber prepared in the step 1 and 20kg of acrylic resin, and placing the polyaniline nano-fiber and the acrylic resin in 30kg of ethyl acetate to stir for 20min to obtain a mixture, wherein the temperature is 20-25 ℃;
and step 3: adding 9kg of organopolysiloxane and 4kg of polyvinyl alcohol into the mixture prepared in the step 2, and stirring for 20min to obtain an emulsified mixture;
and 4, step 4: and (3) adding 25kg of Hexamethylene Diisocyanate (HDI) biuret and 7kg of diazabicyclo [2.2.2] octane into the emulsified mixture prepared in the step (3), and stirring for 10min to obtain the acrylate coating.
Other examples are different from the first example in the components and the mixture ratio thereof, and the components of each example are shown in table 2.
Table 2 components and proportions in the examples
Preparing the acrylate coating according to the above mixture ratio, and carrying out performance test on the acrylate coating. The test basis is as follows: GB/T9286-1998 cut and check test of gas film of color paint and varnish; and (3) hardness testing: GB/T6739-2006 pencil method for measuring coating hardness; heat resistance: testing according to GB/T1735; impact resistance as tested according to GB/T1732-1993; tensile strength and elongation at break were tested according to GB/T1040-92.
The acrylate coatings prepared in the above examples were tested according to the above standards, and the specific test results are shown in table 2.
TABLE 2 test results of the examples
From the results of table 2, it can be seen that the acrylate coatings prepared by the above examples all have relatively strong adhesion and relatively good heat resistance. In the aspect of mechanical property, the impact resistance of the coating can reach 80cm at most, the tensile strength can reach 4.1MPa at most, and the elongation at break can reach 367 at most. The polyaniline nanofiber is added into the coating, the polyaniline nanofiber is in lap joint with other sheet layer components to form a three-dimensional network structure, the polyaniline nanofiber is similar to a lap joint framework, and the tensile strength, the impact resistance and the elongation at break of the coating are improved. Besides being used as a leveling agent, the organopolysiloxane can also enhance the bonding effect between the coating and the base material and enhance the adhesive force.
Comparative example:
the following comparative examples are different in composition from example one, and the components of the comparative examples are shown in table 3.
TABLE 3 Components and proportions in proportions for each pair
The above comparative examples were tested according to the methods of the examples, and the test results are shown in Table 4.
Table 4 comparative test results
The reinforcing agent of the comparative example I is polyaniline solution, the reinforcing agent of the comparative example II is not added, the leveling agent of the comparative example III is not added, the dispersing agent of the comparative example IV is not added, and the commercially available polyaniline is used as the reinforcing agent of the comparative example V. From the data in Table 4, it is understood that if no reinforcing agent is added to the coating material, the impact resistance of the coating material is greatly reduced, and the tensile strength and elongation at break are also greatly reduced, and it is seen that polyaniline nanofibers as reinforcing agents can improve the impact resistance of the coating material. If the polyaniline nanofibers in the coating are replaced with polyaniline solution, the polyaniline exists in the solution in the form of a film, and the reinforcing agent is overlapped with other components in the coating in the form of sheets, so that the strength is reduced. The coating of the third comparative example, in which no leveling agent was added, had a decreased bonding ability with the substrate. No dispersant is added in the coating, so that the components in the coating can be unevenly dispersed, and the tensile strength of the coating is poor.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
