Problems solved by technology

[0011] However, the method disclosed in Patent Document 1 not only does not sufficiently modify the surface properties represented by the wettability index and contact angle, but also cannot maintain the effect for a long time, and also has the problem that the solid substance is easily thermally deformed.
In addition, it was found that it was difficult to uniformly treat solid matter by irradiating flames downward.

Abstract

Provided are a method of modifying the surface of a solid substance that is difficult to bond to an adhesive solid substance without directly using a flame, and a solid substance that has undergone such surface modification. In this method, a gaseous substance containing a modifier compound having at least a silane atom, a titanium atom, or an aluminum atom is sprayed on a solid substance by a heat source at a temperature of 400° C. or higher, or, the modifier compound containing the After the gaseous substance is sprayed on the solid substance, it is heated to 400°C or higher by a heat source, or they are further combined for surface modification.

Description

technical field [0001] The present invention relates to a method for modifying the surface of a solid substance and a surface-modified solid substance, in particular to a method for modifying the surface of a solid substance that can be easily bonded, printed, painted, etc. solid matter. Background technique [0002] The surface of solid substances, such as silicone rubber, fluororubber, polyethylene resin, etc., is mostly hydrophobic or hydrophobic, and it is generally difficult to perform surface treatments such as bonding with other components, printing, and UV coating. In addition, metal surfaces such as stainless steel and magnesium have insufficient adhesion and surface smoothness among metals. When UV-curable coatings are directly applied, there is a problem that the coating film is easily peeled off. In addition, it has also been tried to add inorganic particles such as titanium oxide and zirconium oxide as a photocatalyst to the polymer material, but it has also be...
