Abstract

PROBLEM TO BE SOLVED: To obtain a water repellent film-revivifying agent having high water repellent performance and high in durability of revivified water repellent film and having high shelf life of revivifying agent solution and exhibiting low corrosive property by including a specific water-soluble reaction product as an active ingredient. SOLUTION: This water-repellent film-revivifying agent is obtained by including a water-soluble reaction product obtained by co-hydrolyzing and condensing (A) (i) an alkyl fluoride group-containing alkoxysilane or (ii) a monovalent hydrocarbon group-containing alkoxysilane without containing the component (i) and fluorine atom and/or its reaction product with (B) an amino group- containing alkoxysilane as an active ingredient. A compound of formula I Rf is a polyfluoroalkyl of the formula Cn F2n+1 [)n) is 1-20]; X is a binding group such as CH2 O, CO2 or S; (a) is 0-3; (b) is 1-3; (c) is 0 or 1} is preferable as the component (i). A compound of formula II [R4 and R5 are each H, a 1-15C alkyl, or the like; R6 is a 1-18C divalent hydrocarbon; R7 and R8 are each a 1-4C alkyl; (d) is 0 or 1] is preferable as the component B.

2. Description of the Related Art In recent years,
For example, as chemical parts for automobiles, a water repellent that is applied to a windshield or the like to repel water drops and secure a view is used. However, the water repellent component of such a water repellent is basically polydimethylsiloxane, polymethylphenylsiloxane, or amino-modified siloxane, and does not chemically bond to the surface of the substrate to be treated or has a weak chemical bond. However, the durability of the water-repellent film is poor, and the water-repellent performance immediately deteriorates, resulting in poor visibility in the front and chatter of the wiper, and the water-repellent must be reapplied each time. In recent years, a silane-based water-repellent has been used to chemically bond to the surface of the substrate to be treated to improve durability. However, the water-repellency has deteriorated over time due to surface abrasion and ultraviolet rays. Was.

Recently, water repellent film rejuvenating agents have been put on the market by various companies. However, these water-repellent film revival agents themselves do not have much water-repellent performance, and rather improved the wiper's sliding and improved the cleaning effect so that the coated water-repellent film does not deteriorate. It is not an essential meaning water repellent film revival agent because of many things. Also, the present inventors,
JP-A-9-3403 and JP-A-9-310094, that a coating agent containing a reaction product of a fluoroalkyl group-containing alkoxysilane and an amino group-containing alkoxysilane as a main component is effective as a surface treatment agent or a water-repellent detergent. However, there is no description about application to a water-repellent film revitalizing agent.

Means for Solving the Problems and Embodiments of the Invention The present inventors have conducted intensive studies in order to achieve the above object, and as a result, have found that an alkoxysilane containing an alkyl fluoride group and an alkoxysilane containing an amino group, and Further, when a water-soluble reactant obtained by co-hydrolyzing and condensing a monovalent hydrocarbon group-containing alkoxysilane containing no fluorine atom is used as an active ingredient of the water-repellent film revitalizing agent, this reactant is effective as a water-repellent component. Water-soluble is given to the alkylated alkyl group-containing silane compound itself, and it is easily dissolved in water, so that it has high storage stability, and can provide excellent properties such as excellent water repellency, and its durability. Excellent corrosion resistance and weak acid can be used for co-hydrolysis, so that corrosiveness can be kept low, and it is possible to develop a water-repellent film revival effect only by mixing with water. There was found that conventional water-repellent film revival agent repellent film revival agent having improved many of the problems was having is obtained, in which the present invention has been accomplished.
