Description
Technical Field
The invention relates to the field of building ceramics, in particular to a back-covered thin ceramic plate and a preparation method thereof.
Background
In recent years, thinning of ceramic plates becomes a hot point of industrial research. The thin ceramic plate reduces the use of mineral resources such as clay and the like, and has a significant advantage in practical use due to its light weight. Particularly, the development of the surface decoration process of the ceramic plate promotes the thinned ceramic plate product to have very vivid detailed textures, thereby further expanding the application space of the ceramic plate. Currently, some manufacturers apply thin ceramic plates to the panels of cabinets and refrigerators. However, since ceramic itself is a brittle material, it is easily broken or even broken when subjected to external impact or a large load, and the relatively sharp edges of broken ceramic pieces cause unsafe factors, which may cause potential hazards in the processes of loading and transportation of thin ceramic products.

In view of the above problems, the present invention provides a back-covered thin ceramic plate and a method for manufacturing the same, in which a back-covered net is firmly attached to the back of the thin ceramic plate on an industrial production line, and when the thin ceramic plate is impacted by an external force, most of stress strain energy is absorbed by the back-covered net, so that the mechanical properties of the thin ceramic plate are greatly improved.
In a first aspect, the present invention provides a method for preparing a back-covered thin ceramic plate. The preparation method comprises the following steps:
uniformly applying an adhesive on the surface of the thin ceramic plate in an adhesive pouring or spraying manner; the surface is the back of the thin ceramic plate without glaze decoration and/or pattern decoration;

Detailed Description
The present invention is further illustrated by the following examples, which are to be understood as merely illustrative of, and not restrictive on, the present invention. Unless otherwise specified, each percentage means a mass percentage.
The following is an exemplary description of the method of making the back-covered mesh thin ceramic plate of the present invention.
Preparing a thin ceramic plate to be coated with a net. The composition and the preparation process of the thin ceramic plate are not limited, and the thin ceramic plate can be prepared by adopting a ceramic plate finished product produced by a ceramic manufacturer. It is to be understood that ceramic plates of conventional dimensions may be suitable for use in the present invention. Preferably, the preparation method of the present invention is applied to a thin ceramic plate having a thickness of 3 to 6 mm. In some embodiments, the thin ceramic plate has a specification of 3200-.
And applying adhesive on the surface of the thin ceramic plate. The surface is the back of the thin ceramic plate without the glaze decoration and/or pattern decoration. Although the (manual) coating mode can apply the adhesive, the repeatability of manual operation is poor, the adhesive coating is easy to be uneven, and the adhesive is cured in advance to a certain extent due to long-time coating, which is not favorable for uniform adhesion and surface leveling of the mesh cloth.
According to the invention, the adhesive is uniformly applied to the surface of the thin ceramic plate in an adhesive pouring or spraying manner. For example, the glaze spraying cabinet is used to apply the adhesive on the surface in a glue spraying manner. In order to avoid the influence of the atomized adhesive sprayed to other positions on the production environment, the adhesive spraying equipment needs to be sealed, so that the operation difficulty is improved, and the occupied operation space is caused. In addition, the adhesive is easy to solidify at the spray head and the spray pipe to block the spray head, so that the spray head is difficult to clean, and the uniformity of the sprayed adhesive is further influenced.
As a preferable technical scheme, the glaze pouring device is used for pouring the adhesive on the surface of the thin ceramic plate. In the industrial production of the back-mesh-covered thin ceramic plate, generally, the thin ceramic plate is run at a certain speed on a production line. For example, in order to cure the adhesive resin for a proper curing time, the advancing speed of the thin ceramic board on the production line may be set to 1 to 1.5 m/s. When the adhesive is applied to the surface of the ceramic plate in a vertical falling mode, the adhesive can easily flow to the front surface of the ceramic plate due to good adhesion and fluidity, and glaze decoration and/or pattern decoration are damaged. The included angle between the falling direction of the adhesive and the moving direction of the ceramic plate on the production line is 45-60 degrees in the process of applying the adhesive, so that certain buffering acting force can be generated in the falling process of the adhesive, and the decorative defect caused by adhesive flowing caused by improper application of the adhesive is prevented. If the included angle between the falling direction of the adhesive and the moving direction of the ceramic plate on the production line is too low, the amount of the adhesive falling in unit time is less under the condition of keeping the advancing speed of the thin ceramic plate to be proper. If the falling direction of the adhesive and the moving direction of the ceramic plate on the production line form an excessively high included angle (tend to be vertical), an effective buffering effect cannot be achieved.
The falling direction (glue pouring direction) of the adhesive can be regulated and controlled by arranging the baffle right below the glaze pouring device. The angle of the baffle can be freely adjusted, so that the glue pouring direction can be controlled.
The chemical composition of the adhesive is not limited, and the adhesive can be prepared by adopting the common adhesive in the field. Preferably, the adhesive is a thermosetting resin adhesive with a rigid molecular chain. The thermosetting resin adhesive with the rigid molecular chain has a large number of heat-resistant rigid groups such as aromatic rings, heterocycles and the like on the molecular chain, and the rigid groups enable a cured product to have higher crosslinking density, so that the mechanical property of the back-mesh-covered thin ceramic plate is favorably improved. For example, the adhesive is an epoxy adhesive. The examples specifically use a two-part epoxy AB glue adhesive. The double-component epoxy resin AB adhesive and the mesh fabric have good wettability and rigidity after being cured.
It is to be noted that silicone adhesives (silica gel adhesives) and photocurable adhesives are not suitable for the present invention. The flexible chain of the organic silicon adhesive enables cured organic silicon to be combined with the mesh cloth to form a reinforcing structure similar to 'steel bar-concrete', and the fiber mesh cloth cannot absorb energy transmitted by the plate, so that the impact performance is not obviously improved. In addition, the wettability of the organic silicon adhesive and the mesh fabric is poor, and the mesh fabric and the organic silicon adhesive cannot be effectively and high-quality attached. Also, photo-curable adhesives are susceptible to incomplete cross-linking, which also affects the formation of the reinforcing structure. If a long photo-curing time is adopted, the production rate is seriously affected, and the photo-curing adhesive generally has pungent smell and is harmful to the operating environment and the health of operators.
The application amount of the adhesive is 280-320g/m2. If the application amount of the adhesive is less than 280g/m2In the technical scheme of the invention, the amount of the adhesive cannot fully wrap the mesh cloth, which is not beneficial to improving the impact property of the thin ceramic plate; if the application amount of the adhesive is more than 320g/m2At this time, the adhesive is already fully wrapped on the mesh, and the consumption of the adhesive is continuously increased, so that resource consumption is caused, for example, the curing time is prolonged, and the performance of the ceramic plate is not further improved.
And placing the mesh on the surface of the thin ceramic plate after the adhesive is applied so that the adhesive wets and adheres to the mesh. The material of the mesh cloth is not limited. For example, the mesh cloth is one of a glass fiber mesh cloth, a carbon fiber mesh cloth and a basalt fiber mesh cloth. In the examples, a glass fiber mesh was used.
In experiments, the gram weight of the screen cloth influences the use performance of the back-covered ceramic plate, because the gram weight of the screen cloth influences the distribution density of warp and weft yarns. The larger the gram weight of the mesh fabric is, the better the impact resistance of the thin ceramic plate is theoretically, but more adhesive is required to wrap the mesh fabric. In some embodiments, the web has a grammage of 280-300g/m2At the moment, the mesh sizes between the warp yarns and the weft yarns are moderate, and the mesh cloth can effectively support the adhesive and can be used for subsequent rolling proceduresThe adhesive is forced into the micro space of the mesh by the corresponding downward pressure in the process, and the adhesive is prevented from permeating and penetrating through the meshes, so that a flat surface is favorably obtained.
And sticking release paper on the surface of the thin ceramic plate on which the mesh cloth is placed. The specification of the release paper is adaptively adjusted according to the specification of the thin ceramic plate. Similarly, the material of the release paper is not limited, and can be ceramic paper, silicone oil paper, etc. In the examples, ceramic paper was used specifically.
Rolling on the surface of the release paper. The roller can be used for rolling on the surface of the release paper to remove air bubbles among the adhesive, the mesh and the release paper. The pressure of the roller can be 0.5-1.5 MPa.
And curing the thin ceramic plate to obtain the back-covered thin ceramic plate. The curing may be thermal. In some embodiments, the curing temperature is 80-120 ℃ and the curing time is 30-40 minutes.
If omit the use of anti-sticking paper, the gluing agent sees through the blank adhesion of screen cloth on the roller surface when roller roll-in screen cloth on the one hand, make roller surface unevenness, this can further influence the surface quality of ceramic plate, on the other hand, in the industry in order to avoid the solidification a small amount of gluing agent bonding ceramic plate that still exists, can not place the ceramic plate stromatolite usually when the storage, this has occupied more storage space, the use of anti-sticking paper makes the stromatolite of covering the slim ceramic plate of back of the body net place and becomes possible, extremely strong practicality and economic value have.
The preparation method of the back-covered net thin ceramic plate overcomes the technical problems of easy glue flowing, difficult control and low efficiency in gluing, the obtained back-covered net thin ceramic plate has high surface flatness, excellent mechanical properties such as impact strength, breaking strength and the like, the industrial continuous production of the back-covered net thin ceramic plate is realized, and the practical convenience is provided for the storage of the ceramic plate while the productivity is greatly improved. For example, the production method of the back-mesh-covered thin ceramic plate has an industrial daily output of 1000 squares or more.
If the mesh cloth is adhered to the back surface of the ceramic plate with concave-convex parts, the mesh cloth and the back surface can be tightly adhered, but the mesh cloth is difficult to be flatly spread on the surface of the ceramic plate. When the back has the concave points, the coating of the adhesive is uneven, and the final adhering effect is affected. The preparation method of the invention can be carried out on the back surface of the flat ceramic plate without designing the back surface of the ceramic plate to be provided with the back surface consisting of the plane and the concave points. In particular, a layer of silane coupling agent can be coated on the back surface of the ceramic plate to enhance the bonding force between the backing net and the ceramic plate.
The present invention will be described in detail by way of examples. It is also to be understood that the following examples are illustrative of the present invention and are not to be construed as limiting the scope of the invention, and that certain insubstantial modifications and adaptations of the invention by those skilled in the art may be made in light of the above teachings. The specific process parameters and the like of the following examples are also only one example of suitable ranges, i.e., those skilled in the art can select the appropriate ranges through the description herein, and are not limited to the specific values exemplified below.
Example 1
The preparation method of the back-covered thin ceramic plate comprises the following steps:
uniformly applying an adhesive on the surface of the thin ceramic plate in an adhesive pouring mode;
placing the mesh on the surface of the thin ceramic plate to which the adhesive is applied so that the adhesive wets and adheres to the mesh;
sticking anti-sticking paper on the surface of the thin ceramic plate on which the mesh cloth is placed;
rolling on the surface of the release paper to remove interlayer gas among the adhesive, the mesh and the release paper and promote the surface to be smooth;
and curing the thin ceramic plate to obtain the back-covered thin ceramic plate.
The impact height was based on JC/T908-2013 ball drop impact. The impact height of the original thin ceramic plate was 0.2 m.
The gram weight of the mesh and the application amount of the adhesive are key factors influencing the impact resistance of the thin ceramic plate covered with the mesh. The mesh cloth has overlarge gram weight, more compact structure, thicker warp and weft, more adhesive is needed to wrap the mesh cloth, the needed curing time is prolonged, the performance is excessive,the overall thickness of the composite board is also increased, which affects the decoration. Too low gram weight of the mesh cloth can cause the limited stress absorption effect of the composite board to cause the impact resistance not to reach the standard. The mesh cloth can be effectively wrapped by the adhesive through the matching of the appropriate gram weight of the mesh cloth and the application amount of the adhesive, so that the impact height of the back-covered thin ceramic plate is improved. When the application amount of the adhesive is 280-320g/m2The gram weight of the mesh cloth is 280-300g/m2In this case, the impact height of the back-mesh-covered thin ceramic plate is 1.0m or more, preferably 1.0 to 1.4 m. However, if the weight of the mesh fabric is outside the range of the applied amount of the adhesive, the impact strength of the back-mesh-covered thin ceramic plate cannot be increased to 5 times or more as high as that of the original thin ceramic plate, although the flexural strength is slightly increased.
And (4) carrying out a flexural strength test on the back-covered thin ceramic plate. When the application amount of the adhesive is 280g/m2The gram weight of the mesh cloth is 300g/m2When the back-covered net thin ceramic plate is used, the bending strength of the back-covered net thin ceramic plate is 1.5 times that of the original thin ceramic plate. In the process that the plate is pulled, the adhesive and the mesh form a structure similar to reinforced concrete, so that partial tension is counteracted, and the fracture resistance is improved.
And carrying out peel strength test on the back-covered thin ceramic plate. In the process, the gram weight of the mesh cloth and the matching of the adhesive have important influence on the peeling strength of the back-covered thin ceramic plate. When the application amount of the adhesive is 280-320g/m2The gram weight of the mesh cloth is 280-300g/m2When the ceramic plate is used, the covering net of the back-covering net thin ceramic plate is difficult to tear from the ceramic plate body.
Comparative example 1
The preparation method of the back-covered thin ceramic plate comprises the following steps:
uniformly applying an adhesive on the surface of the thin ceramic plate in an adhesive pouring mode;
placing the mesh on the surface of the thin ceramic plate to which the adhesive is applied so that the adhesive wets and adheres to the mesh; the gram weight of the mesh cloth is 300g/m2When the amount of the adhesive applied is 100g/m2；
Sticking anti-sticking paper on the surface of the thin ceramic plate on which the mesh cloth is placed;
rolling on the surface of the release paper to remove interlayer gas among the adhesive, the mesh and the release paper and promote the surface to be smooth;
and curing the thin ceramic plate to obtain the back-covered thin ceramic plate.
The back-covering net is easy to tear from the thin ceramic plate body because the adhesive does not completely wrap the net cloth, and part of the net cloth is still exposed, so that the strength is low.
Example 2
The preparation method of the back-covered thin ceramic plate comprises the following steps:
uniformly applying an adhesive on the surface of the thin ceramic plate in an adhesive spraying manner;
placing the mesh on the surface of the thin ceramic plate to which the adhesive is applied so that the adhesive wets and adheres to the mesh;
sticking anti-sticking paper on the surface of the thin ceramic plate on which the mesh cloth is placed;
rolling on the surface of the release paper to remove interlayer gas among the adhesive, the mesh and the release paper and promote the surface to be smooth;
and curing the thin ceramic plate to obtain the back-covered thin ceramic plate.
Spout gluey needs to set up sealed environment, and atomizing gluing agent granule can produce otherwise and splash, and the gluing agent atomizes into very easy adhesion after the granule and is spouting gluey equipment, is unfavorable for the cleanness, has restricted the use of spouting the glue above.
