However, as a practical matter, no matter what kind of glass material is loaded into the thermal spraying device, the glass coating is never easily formed, and depending on the material, the glass material is not melted at all and is sprayed in the powder form as it is. It may be discharged from the device. 2500 in glass spraying equipment
It is possible to raise the temperature up to about 3200 ° C. or 7000 ° C. or more in the case of plasma spraying, but a certain amount of time is required for melting the glass material into a glass state. However, in the case of a thermal spraying device, the material is discharged at an instantaneous speed, and therefore, the glass material must be compatible with such properties. This also applies to a plasma spraying apparatus that can obtain a high temperature.

Further, in the actual thermal spraying, the object to be coated is preheated, and it is strongly required to lower the preheating temperature in actual construction.

It is an object of the present invention to provide a glass material that can easily perform thermal spraying for forming a glass coating on the surface. In particular, it is an object of the present invention to provide a glass material that can be quickly melted in the flame (frame) of the thermal spraying device. Another object of the present invention is to provide a glass spray material which can be sprayed onto an object to be coated at a relatively low preheating temperature.

First, for the main component (A), SiO 2 is the main glass-forming oxide and has a great influence on the coefficient of thermal expansion, the softening point and the wear resistance. It should be noted that as the amount of SiO 2 increases, the wear resistance, weather resistance, and acid resistance increase and the performance of the glass coating improves, but if it is too large, the fire resistance of the glass material increases and the spraying temperature must be increased. Disappear. Therefore, in order to lower the preheating temperature of the object to be coated, SiO 2 is 55 to 70%.

The reason why the B 2 O 3 content is 8 to 15% is that the higher the content, the worse the wear resistance, weather resistance and acid resistance, but the lower the fire resistance temperature. From the relationship with other components in the present invention, about 8 to 15% is preferable in this relationship. B 2 O 3
If the amount is increased, the melting of the thermal spraying device during the fire will be performed quickly.

Adding 10 to 20% of Li 2 O increases the electric resistance of the product,
It is also for increasing hardness and improving chemical durability, especially acid resistance. Further, since the expansion coefficient is large, it can be adjusted to the expansion coefficient of the base material by a small amount of adjustment. Replacing soda with Li 2 O causes a decrease in specific gravity, an increase in coefficient of thermal expansion, an increase in fluidity, a decrease in melting temperature, and a decrease in softening and solidifying temperatures. Therefore, as far as the expansion coefficient allows, it is desirable to mix them, and the more they are mixed, the faster they melt in the frame and the gloss increases.

Al 2 O 3 is effective in increasing the viscosity of the glass coating and preventing phase separation. Phase separation and the separation phenomenon occurs in a range of components that when heat is applied is a glass coating, means that Excessive SiO 2 is separated from the filtrate that less SiO 2. Also Al
2 O 3 is a glass forming auxiliary component and improves the performance of the glass coating. Al 2 O 3 is added within the range of 1 to 5%.

CaO acts as a fluxing agent but improves chemical durability. That is, it increases resistance to the dissolving action of water.
Also, the hardness is increased, so that the resistance to abrasion and weathering is also increased. Further, compared with the action of alkali, the tensile strength is increased and the expansion coefficient is remarkably lowered, so that cracks can be prevented. Also, when melted, the viscosity also decreases.

SrO also acts as a flux, increasing fluidity, lowering the softening temperature and increasing the degree of melting. When CaO or BaO is replaced with SrO, the reaction with the base material is promoted, the adhesion of the glass material is further improved, and the peel strength is increased.

One or two or more of O and CeO 2 are added in a total amount of 10% or less because the main component and the auxiliary component, or the synergistic action of the auxiliary components can lower the fire resistance of the glass material. Is. In addition, the melting of the glass material at the time of thermal spraying is quickly performed by these auxiliary components. Furthermore, depending on the amount of these auxiliary components added, the film performance such as weather resistance and acid resistance can be improved.

ZnO acts as a solvent and gives the glass material luster,
It limits the action of the chromophore and sometimes gives it an emulsion. However, the viscosity increases so much that many cannot be added. Further, when both ZnO and SrO are used, the fluidity of the glass becomes large, so that it becomes easy to form a smooth glass surface and pinholes are reduced. Further, ZnO prevents shrinkage of the glass material, thereby preventing exfoliation of the glass material as a result of shrinkage and preventing carbon from adhering to the glass coating during thermal spraying.

MgO,ZnOなどの粘度を大きくする成分は、先に述べた
主成分のAl2O3と同様に分相防止に役立つ。
Components that increase the viscosity, such as MgO and ZnO, are useful for preventing phase separation, like the main component Al 2 O 3 described above.

TiO 2 , ZrO 2 , BaO, and Sb 2 O 5 are added in small amounts to lower the fire resistance of the glass and increase the acid resistance.

By adding a small amount of, for example, it is possible to lower the degree of resistance of the glass and to lower the thermal spraying temperature.
