Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
The common door plate materials in the household appliance industry at present are steel plates and glass. However, both steel plates and glass have certain limitations due to their material properties. The steel plate has poor corrosion resistance and plasticity, and cannot be recovered to a normal use state after being subjected to destructive force exceeding the yield strength. Glass is an amorphous structure, which has limitations on its shape and surface feel. With the deepening of stone industry, compared with steel plates and glass, the stone material has soft touch and high-grade visual effect, so that the stone material is popular with consumers. However, the strength of the stone is not high, so that multiple processes are needed to process the stone to ensure the strength of the stone, and the processes are multiple and complicated when stone components are manufactured. In addition, in the household appliance industry, the problems of cracking and falling off of the stone material and the like still occur in the use process of the stone material component due to insufficient strength and hardness, and the impact strength and hardness of the stone material still do not meet the use requirements of household appliance products.
In order to solve the household electrical appliances trade, the stone material part is because of intensity and hardness not enough the stone material fracture appear in the in-process that uses, and the scheduling problem drops, and first aspect refers to fig. 1, and this application provides a ceramic panel, including substrate layer 13, substrate layer 13 is made by ceramic stone material and reinforcing fiber, and substrate layer 13 is the major structure who constitutes ceramic panel 1, and follow-up preparation ceramic panel 1's process steps all are based on substrate layer 13 goes up to carry out further processing.
In some embodiments, the ratio of the ceramic stone material to the reinforcing fiber used to prepare the substrate layer 13 ranges from 10:1 to 50: 1. The ceramic stone is a main material for preparing the substrate layer 13, and is made of one or more of kaolinite, silicon carbonate, albite and calcium carbonate, and clay. The purpose of adding the reinforcing fibers into the ceramic stone is to improve the strength of the prepared base material layer 13 through the physical characteristics of high temperature resistance, friction resistance, heat conduction and corrosion resistance of the reinforcing fibers, so that the base material layer 13 can have the strength which can be borne when the base material layer is used by a household appliance. The reinforced fiber is one or more of aluminum sulfate fiber, glass fiber, non-woven fabric fiber or plant fiber.
The larger the content ratio of the reinforcing fibers in the material of the substrate layer 13 is, the higher the strength of the substrate layer 13 is. However, in the household appliance industry, the strength of the substrate layer 1 is too high, so that the manufactured ceramic panel 1 cannot be adapted to most household appliances. Therefore, the content ratio of the ceramic stone material and the reinforcing fiber used for preparing the substrate layer 13 is in the range of 10:1 to 50:1, which is the optimal ratio range.
One side of the substrate layer 13 is mounted with a refrigerator door; the other side is covered by a touch layer 12 and a pattern layer 11 in sequence; the tactile layer 12 is directly covered on the base material layer 13, and the tactile effect of the ceramic panel 1 can be improved, and the pattern layer 11 is covered on the tactile layer 12, and the gloss effect of the surface of the ceramic panel 1 is further improved.
The preparation method of the touch layer 12 and the pattern layer 11 comprises the following steps:
firstly, coating an ink layer on one side surface of a base material layer 13; the ink in the ink layer is one or more of water-based paint, real stone paint, sand wall paint and fluorocarbon paint.
Secondly, firing the substrate layer 13 coated with the ink layer, wherein the firing temperature is 800-1200 ℃, and the firing time is 10-30 seconds, so as to obtain the touch layer 12 and the pattern layer 11 after the ink layer is separated; the tactile layer 12 is formed by a part of an ink layer directly contacting with a base material layer 13, the pattern layer 11 is a solid layer formed by residual ink in the ink layer, and the raw material of the pattern layer 11 is the ink in the coated ink layer.
During the firing, the portion of the ink layer directly contacting the substrate layer 13 is converted into the touch layer 12 by the high temperature, and the remaining ink not converted into the touch layer 12 is dried slowly in a natural state to form the pattern layer 11 and adheres to the touch layer 12. The tactile layer 12 and the pattern layer 11 can simultaneously protect the side of the ink layer coated on the substrate layer 13, and prevent the substrate layer 13 from being directly exposed to the air, and the ceramic panel 1 from being discolored or reduced in strength due to oxidation with oxygen present in the air. The touch layer 12 and the pattern layer 11 may further protect the substrate layer 13 from being hit by the outside to leave marks such as scratches and scratches, which may affect the appearance of the ceramic panel 1.
In some embodiments, as shown in fig. 1, the ceramic panel 1 further includes a protective layer 14 covering one side of the substrate layer 13 not coated with the ink layer; the protective layer 14 is any one of a non-metal protective layer, a metal protective layer, or a chemical protective layer. The protective layer 14 may further protect the other side (the side on which the ink layer is not coated) of the base material layer 13. And the other side surface of the substrate layer 13 is prevented from being scratched and collided when being installed with the refrigerator door and remaining scratches and scratches. When retrieving ceramic panel 1 on the abandonment refrigerator door, the recovery personnel can directly peel off ceramic panel 1 from the refrigerator door from substrate layer 13 and protective layer 14, guarantee the integrality of substrate layer 13 in order to carry out follow-up reutilization.
