Description

The present invention relates to a wear-resistant material. That is, the present invention relates to a wear-resistant material in which a coating layer is formed on the surface of a metal base material and thus has excellent wear resistance and is widely used in various applications.

"Prior art" Such wear-resistant materials are provided with properties such as excellent wear resistance, corrosion resistance, etc. by forming a coating layer consisting of resin and ceramic on the surface of the metal base material. It had been. Conventionally, the seed coating layer has a single-layer structure, is formed from a single resin and ceramics, and is adhesively coated on a metal base material.

"Problems to be Solved by the Invention" The following problems have been pointed out in such conventional wear-resistant materials.

First, when a resin having a high flexibility is used as the resin of the coating layer, there has been a problem that the resin and the coating layer are easily damaged.

Second, when a resin having a high hardness is used as the resin of the coating layer, there is a problem that the resin and the coating layer are easily broken and damaged when subjected to an impact.

Third, in addition to the above, the coating layer is required to have a bonding strength to both the metal base material and the ceramic for the resin, and the material is limited. Was pointed out.

 In the prior art, such a point was pointed out.

The present invention has been made in view of such circumstances, and has been made in order to solve the problems of the above-described conventional example, and comprises an underlayer coating having a predetermined function, which is made of a predetermined resin and ceramic, and a predetermined resin and ceramic. To propose an abrasion-resistant material that has a multilayer structure in which the upper layer coating is combined with the surface of a metal base material to reduce damage, breakage, etc., and excel in abrasion resistance, corrosion resistance, etc. With the goal.

"Means for Solving the Problems" The technical means of the present invention for achieving the object is as follows.

This wear-resistant material has a multilayer structure in which a lower layer coating made of a highly flexible resin and ceramic and an upper layer coating made of a resin and ceramic having high hardness are sequentially laminated on the surface of a metal base material.

As the resin having high flexibility of the lower layer coating, a resin having a high bonding strength with a metal is used, and as the resin having a high hardness of the upper layer coating, a resin having excellent wear resistance and corrosion resistance is used. Those with high strength are used.

The lower layer coating has a function of protecting the metal base material without being damaged or damaged even when the upper layer coating is broken and damaged by an external impact.

"Operation" The present invention operates as follows because it is constituted by such means.

This wear-resistant material has a lower coating and an upper coating on a metal base material. In other words, a lower layer coating made of resin and ceramic that has high bonding strength to metal and high flexibility, and an upper layer coating made of resin and ceramic that has high abrasion resistance and corrosion resistance and strong bonding strength to ceramic And The lower layer coating does not break even if the upper layer coating is broken and damaged, and has a function of protecting the metal base material. Then, this wear resistant material is
The second and third are as follows.

First, a lower layer coating made of a highly flexible resin is covered with an upper layer coating. That is, the lower layer coating is
It is covered with an upper layer coating made of a resin and ceramics, which have excellent wear resistance and corrosion resistance, have high bonding strength with ceramics, and high hardness. Therefore, the lower layer coating and the metal base material are protected by the upper layer coating, and are less likely to be damaged and are less damaged. Therefore, the entire wear-resistant material is hardly damaged and has little damage.

Second, the lower layer coating, that is, the lower layer coating made of resin and ceramics, which has high bonding strength with metal and high flexibility,
It is interposed between the upper coating using a resin having high hardness and the metal base material. The lower layer coating does not break even if the upper layer coating is broken and damaged.

Therefore, when an external impact is applied, even if the upper layer film is broken and damaged, the lower layer film containing ceramics and having a high bonding strength with the metal base material is not affected by such breakage and damage. Protected. Therefore, the entire wear-resistant material is hardly broken and has little damage.

Thirdly, since the lower layer coating is made of a resin having high bonding strength with metal and high flexibility, first, the lower layer coating has high bonding strength to the metal base material and is hardly peeled off. Further, since the lower layer coating is made of resin, the bonding strength to the upper layer coating is high, and the lower layer coating is hardly peeled off.

That is, in the present invention, as in the above-described conventional example, the resin is required to have a joint strength to both the metal base material and the ceramic at the same time, so that the material is not limited. In the present invention having a laminated structure, the resin for the lower layer coating is selected to have a particularly strong bonding strength with metal, and the resin for the upper layer coating is selected for the resin having a particularly high bonding strength with ceramics.

As described above, in this wear-resistant material, a resin having an excellent wear resistance and corrosion resistance and a high bonding strength with ceramics are selected especially for the resin of the upper layer coating, and the resin such as wear resistance and corrosion resistance is selected. Notably better.

"Examples" Hereinafter, the present invention will be described in detail based on examples shown in the drawings.

 First, the configuration and the like will be described.

FIG. 1 is a perspective view showing an embodiment of the present invention. Second
The figure is an enlarged front sectional view of the main part.

In this wear-resistant material, a lower layer coating 4 made of a resin 2 and a ceramic 3 having high flexibility and an upper layer coating 7 made of a resin 5 and a ceramic 6 having high hardness are sequentially laminated on the surface of a metal base material 1. It has a multilayer structure.

To describe these in detail, first, various metals are appropriately used as the metal base material 1, and a thin plate-shaped one having a large thickness is used. Next, as the resin 2 having low hardness and high flexibility, for example, a resin having a relatively high bonding strength to a metal when the content of the ceramics 3 is the same, such as an epoxy resin, is used. Examples of the resin 5 having high hardness include acrylic, Teflon, and melanin resins.
When the content of the ceramics 6 is the same, a resin having relatively excellent wear resistance, corrosion resistance, and the like, and having a high bonding strength with the ceramics 6 is used.

As the ceramics 3 and 6, for example, oxides, nitrides, carbides, and borides are used. Such ceramics 3 and 6 are used in the form of a powder, a fine particle, or a fiber formed from these.

The wear-resistant material is made of such a flexible resin 2.
A lower layer coating 4 in which resin and ceramics 3 are composited and an upper layer coating 7 in which resin 5 having high hardness and ceramics 6 are composited are sequentially laminated on the metal base material 1. Although this wear-resistant material has a two-layer structure in the illustrated example, it is needless to say that it can have a multilayer structure of more layers.
For example, it is conceivable to provide a coating layer made of a composite of a special functional resin and ceramic on the outermost surface on the upper coating 7.

The lower coating 4 receives an impact from the outside, and the upper coating 7
Has a function of protecting the metal base material 1 without being damaged or damaged even if it is broken and damaged.

 The above is the description of the configuration and the like.

 Next, the manufacturing method will be described.

The wear-resistant material thus configured is, for example, the following first and second
2, Manufactured as a third.

First, the wear-resistant material is manufactured as shown in the perspective view of FIG. That is, a resin sheet 4 ′ in which a resin 2 and a ceramic 3 having high flexibility are compounded to form a film, and a resin sheet in which a resin 5 and a ceramic 6 having high hardness are similarly compounded to form a film 7 '
Are prepared in advance. These resin sheets 4 ′ and 7 ′ are sequentially arranged on the metal base material 1, and then melt-hardened by heating and pressurizing. As a result, a predetermined lower layer coating 4 and a predetermined upper layer coating 7 are formed by the resin sheet 7 '.

According to the first manufacturing method, the lower layer coating 4 and the upper layer coating 7 can be formed with a time lag with time and can be formed simultaneously and simultaneously. Has the advantage that the manufacturing time is reduced.

Second, the wear resistant material is manufactured as shown in the perspective view of FIG. That is, for the lower layer coating 4, a viscous liquid obtained by compounding the resin 2 and the ceramics 3 having high flexibility is used. For the upper layer coating 7, the resin 5 and the ceramics 6 having high hardness are the same. A viscous liquid that has been compounded is used. Then, these are sequentially applied on the metal base material 1 and then cured by heating. Then, these are sequentially adhered and coated on the metal base material 1 to form a predetermined lower layer coating 4 and a predetermined upper layer coating 7 respectively. Leads to.

In the second manufacturing method, the lower layer coating 4 and the upper layer coating 7 are shifted in time with time.
Next, an upper layer coating 7 is formed in this order. In the above example, so-called one-component resins 2, 5 were used, and heating was performed, but so-called two-component resins 2, 5, which consist of a main agent and a curing agent and are generally used as an adhesive, are used. If
These are cured at room temperature, and the lower coating 4 and the upper coating 7
Are formed.

Third, the wear-resistant material is manufactured as shown in the enlarged front sectional view of FIG. That is, for the lower layer coating 4, a resin in which both the resin 2 and the ceramics 3 having high flexibility are mixed together forming particles is used, and for the upper layer coating 7, the resin 5 and the ceramics 6 having high hardness are similarly used. Both particles are mixed and used. After these are sequentially arranged on the metal base material 1, they are melted and hardened while being compounded by heating and pressing, and then these are sequentially adhered and coated on the metal base material 1, and a predetermined lower coating 4 and an upper coating 7 are formed. Are respectively laminated.

According to the third manufacturing method, similarly to the first manufacturing method, the lower film 4 and the upper film 7 can be formed with a time lag with time, and can be simultaneously performed simultaneously. It can be formed, and has the advantage of shortening the manufacturing time in the latter case of simultaneous and parallel operation.

 The above is the description of the manufacturing method.

Therefore, the lower layer coating 4 and the metal base material 1 are protected by the upper layer coating 7 and are less likely to be damaged and have less damage. As a result, the entire wear-resistant material is less likely to be damaged and has less damage.

Second, the lower layer coating 4 using the resin 2 having high flexibility
Is the upper coating 7 using the resin 5 having high hardness and the metal base material 1.
It is interposed in between. Therefore, when an external impact is applied, for example, even if the upper layer coating 7 is broken and damaged, the lower layer coating 4 is not damaged and damaged, and the metal base material 1 is protected. Therefore, the entire wear-resistant material is hardly broken and has little damage.

Thirdly, in addition to these, for example, the lower layer coating 4 is made of the resin 2 having high flexibility, so that the bonding strength to the metal base material 1 is high and it is difficult to peel off. Also, the bonding strength with respect to No. 7 is strong and the peeling is difficult.
