Description
Technical Field
The utility model belongs to the technical field of the acrylic acid finish technique and specifically relates to an acid and alkali-resistant adheres to acrylic acid finish by force.
Background
The finish paint is a final coating of coating, is a layer coated finally in the decoration of a building wall, and the overall effect presented after the decoration is reflected by the layer. Therefore, the coating has higher requirements on the used materials, not only has good chromaticity and brightness, but also has the characteristics of good pollution resistance, aging resistance, moisture resistance, good mildew resistance, no environmental pollution, safety, no toxicity, no fire hazard, convenient construction, fast drying of a coating film, good light and color retention, good air permeability and the like. Has decorative and protective functions, such as color, luster, texture, etc., and also requires resistance to harsh environments. The finish paint is particularly a coating structure solidified on a building material.
The existing acrylic acid has excellent adhesive force for wall coating, for example, Chinese patent discloses an environment-friendly thermosetting acrylic acid coating for buildings and a preparation method thereof, patent No. 201410202319.2 and publication No. 103952046B, and the acrylic acid coating can generate good adhesive force for wall surfaces through thermosetting. Although the acrylic coating is claimed to have acid and alkali resistance, the fact that the alkaline substance causes certain destructiveness to the acrylic coating is found in practice because the acrylic coating contains silicon dioxide, and the substance and the alkaline substance are very easy to react to generate salts.
Because this technical scheme exists this defect, lead to the construction difficulty, if brush a layer of protective coating to other, this layer of protective coating must be destroyed when carrying out the heating, influence the outward appearance; if the protective coating is not added, the acid and alkali resistance can not be well achieved in the using process. In addition, aluminum plate suspended ceilings are adopted as interior decorations of many buildings at present, and the existing acrylic finish has adhesive force to walls, but the adhesive force to the aluminum plates is slightly poor.
Disclosure of Invention
The utility model provides a not enough to prior art, the utility model provides a can produce stronger adhesive force and have acid and alkali resistance's finish paint to aluminum plate.
The technical scheme of the utility model is that:
the acid and alkali resistant strong adhesion acrylic acid finish paint is characterized in that: the paint comprises a base layer, a chemical conversion layer and a paint layer, wherein the paint layer comprises a thermosetting acrylic coating layer and a protective layer, the top surface of the base layer is coated with the chemical conversion layer, the top surface of the chemical conversion layer is coated with the thermosetting acrylic coating layer, and the top surface of the thermosetting acrylic coating layer is coated with the protective layer.
Specifically, the base layer is an aluminum plate.
Specifically, the chemical conversion layer is an acrylic resin layer.
Specifically, the protective layer is a high-temperature-resistant heat-insulating coating, specifically a high-temperature-resistant heat-insulating coating disclosed in chinese patent No. 201610767325.1. Has the functions of high temperature resistance, heat preservation, acid and alkali resistance and the like.
In one embodiment, the paint layer comprises a bottom layer, a surface layer and a protective layer, wherein the bottom layer is a polyurethane primer layer, and the surface layer is a thermosetting acrylic resin surface paint layer.
The utility model has the advantages that: a surface which is favorable for the adhesion of the thermosetting acrylic acid material is constructed on the surface of the aluminum plate through a chemical conversion layer, and then the thermosetting acrylic acid material is protected by the acid-alkali-resistant protective layer which is not feared by high temperature, so that the whole finish coat has the advantages of good adhesion, mildew resistance, acid-alkali resistance and long service life. In addition, because thermosetting acrylic acid material needs the curing of heating, the utility model discloses an inoxidizing coating does not take place obvious deformation or discolours under the heating state, and very suitable cooperation thermosetting acrylic acid material makes the finish paint use.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, base layer; 2. a chemical conversion layer; 3. a thermosetting acrylic coating layer; 4. a protective layer; 5. and (5) a paint layer.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
example 1
As shown in fig. 1, the acid and alkali resistant acrylic topcoat comprises a base layer 1, a chemical conversion layer 2 and a paint layer 5, wherein the paint layer 5 comprises a thermosetting acrylic paint layer 3 and a protective layer 4, the top surface of the base layer 1 is coated with the chemical conversion layer 2, the top surface of the chemical conversion layer 2 is coated with the thermosetting acrylic paint layer 3, and the top surface of the thermosetting acrylic paint layer 3 is coated with the protective layer 4.
The base layer 1 is an aluminum plate.
The chemical conversion layer 2 is an acrylic resin layer.
The protective layer 4 is a high-temperature-resistant heat-insulating coating, in particular a high-temperature-resistant heat-insulating coating disclosed in Chinese patent No. 201610767325.1. Has the functions of high temperature resistance, heat preservation, acid and alkali resistance and the like.
In this embodiment: the thickness of the chemical conversion layer is 80 microns, the thickness of the thermosetting acrylic coating is 120 microns, the thickness of the protective layer is 60 microns, and the total thickness is 260 microns.
The coatings of this example were tested for coating adhesion by the scribe-and-scribe method (x-cut tape test).
The test procedure was as follows:
using a tool: art designing knife, translucent pressure sensitive adhesive tape.
The procedure is as follows:
1) cleaning and drying the surfaces of 7 coatings obtained by adopting the process flow of the embodiment 1;
2) stably cutting and coating the substrate (aluminum plate) along a straight line by using an art designing knife, wherein the included angle is 45 degrees, the scribing length is 40 millimeters, and the cross point is in the middle of scribing to ensure that the metal substrate is scribed;
3) placing the adhesive tape at the intersection of the cutting lines, and leveling by hand;
4) the tape was torn off at 180 degrees from the painted surface, and the state of the coating after being pulled apart was observed, where no detachment was found at all as 5a, a certain detachment was found along the cut mark as 4a, a detachment gap (width) as large as 1.6 mm as 3a, a detachment gap as large as 3.2 mm as 2a, and a detachment area exceeding the maximum range of the scribe line as 1 a.
And (3) testing results: the results of 7 tests are 4a, which shows that the adhesive force is stronger.
