preparation example Construction

[0036] The preparation method of the back-covered thin ceramic plate of the present invention overcomes the technical problems of easy flow of glue, difficulty in control, and low efficiency when applying glue, and the obtained back-covered thin ceramic plate has high surface flatness, high impact strength and flexural strength. And other excellent mechanical properties, realize industrial continuous production of back-covering thin ceramic plates, while greatly improving production capacity, it also provides practical convenience for the storage of ceramic plates. For example, the industrialized daily output of the preparation method of the mesh-backed thin ceramic plate is more than 1000 square meters.

[0037]If the mesh cloth is adhered to the back of the ceramic plate with concave and convex parts, although the mesh cloth and the back can be closely bonded, it is difficult for the mesh cloth to spread evenly on the surface of the ceramic plate. When there are pits on the ...

Embodiment 1

[0040] The preparation method of the back-covered thin ceramic plate comprises the following steps:

[0041] Apply the adhesive evenly on the surface of the thin ceramic plate by pouring glue;

[0042] Place the mesh on the surface of the thin ceramic plate after applying the adhesive to make the adhesive wet and adhere to the mesh;

[0043] Paste anti-sticking paper on the surface of the thin ceramic plate after placing the mesh cloth;

[0044] Rolling on the surface of the release paper to remove the interlayer gas between the adhesive, mesh and release paper and to make the surface smooth;

[0045] The thin ceramic plate is solidified to obtain the thin ceramic plate covered with a mesh.

[0046] The impact height is carried out according to JC / T908-2013 falling ball impact. The impact height of the original thin ceramic plate is 0.2m.

[0047] The grammage of mesh and the amount of adhesive applied are the key factors affecting the impact resistance of thin ceramic pla...

Embodiment 2

[0059] The preparation method of the back-covered thin ceramic plate comprises the following steps:

[0060] Apply the adhesive evenly on the surface of the thin ceramic plate by spraying glue;

[0061] Place the mesh on the surface of the thin ceramic plate after applying the adhesive to make the adhesive wet and adhere to the mesh;

[0062] Paste anti-sticking paper on the surface of the thin ceramic plate after placing the mesh cloth;

[0063] Rolling on the surface of the release paper to remove the interlayer gas between the adhesive, mesh and release paper and to make the surface smooth;

[0064] The thin ceramic plate is solidified to obtain the thin ceramic plate covered with a mesh.

[0065] Glue spraying requires a sealed environment, otherwise the atomized adhesive particles will splash, and the adhesive is easily adhered to the glue spraying equipment after being atomized into particles, which is not conducive to cleaning, which limits the use of spray glue.

Abstract

The invention discloses a back mesh-coated thin ceramic plate and a preparation method thereof. The preparation method comprises the following steps: uniformly applying an adhesive on the surface of a thin ceramic plate in a glue spraying or glue spraying manner, wherein the surface is the back surface, without glaze decoration and / or pattern decoration, of the thin ceramic plate; placing screen cloth on the surface of the thin ceramic plate to which the adhesive is applied, so that the adhesive wets and adheres to the screen cloth; adhering release paper to the surface of the thin ceramic plate on which the screen cloth is placed; rolling the surface of the release paper to remove interlayer gas among the adhesive, the screen cloth and the release paper and promote the surface to be flat; and curing the thin ceramic plate to obtain the thin ceramic plate coated with the back mesh. By means of the method, the firmly-attached back covering net can be formed on the back face of the thin ceramic plate on an industrial production line, when the ceramic plate is impacted by external force, most stress strain can be absorbed by the back covering net, and the mechanical performance of the thin ceramic plate is greatly improved.

Description

technical field [0001] The invention relates to the field of architectural ceramics, in particular to a thin ceramic plate with back covering and a preparation method thereof. Background technique [0002] In recent years, the thinning of ceramic plates has become a hot spot in industry research. Thin ceramic plates reduce the use of mineral resources such as clay and have significant advantages in practical applications due to their light weight. In particular, the development of ceramic plate surface decoration technology has enabled thinned ceramic plate products to have very realistic detailed textures, which further expands the application space of ceramic plates. At present, some manufacturers have applied thin ceramic plates to cabinets and refrigerator panels. However, ceramic itself is a kind of brittle material, which is easy to be damaged or even broken when it encounters external impact or bears a large load. There are potential hidden dangers in the process o...
