Problems solved by technology
This method is superior to the dry method in that it does not use a vacuum process, but requires long-term high-temperature heating and humidification to stabilize the adhesion of the waterproof and oil-repellent layer, so there are problems in terms of productivity and cost. From the point of view of the problem that the substrates that can be applied are limited

[0302] [Formation of primer layer]
[0303] Primer layers 1 to 5 were respectively formed on an acrylic resin substrate (Acryl de la glass A manufactured by Engineering Test Service Co., Ltd., a test piece substrate with a thickness of 2 mm, a width of 50 mm, and a length of 100 mm) by the method shown below. .
[0304] [Formation of primer layer 1]
[0305] The above-mentioned base material is dip-coated with a treatment solution in which a hydrolysis-dehydration condensation compound of tetraethoxysilane (weight average molecular weight: 25,000, amount of silanol groups: 0.01 mol / g) is diluted with butanol to a solid content of 0.5% by mass Thereafter, it was dried at room temperature (25° C.) for 1 hour to form a primer layer 1 with a thickness of 20 nm on the substrate. For dip coating, the base material was dipped in the treatment liquid for 30 seconds, and then lifted at 150 mm / min.
[0306] [Formation of primer layer 2]
[0307] After dip coating the above substrate...

Abstract
The water-repellent, oil-repellent member is obtained via a method comprising: a step for wet-coating a substrate surface with a solution containing an organic silicon compound comprising multiple silanol groups and a solvent; a step for drying the solvent to form a primer layer; a step for wet-coating the primer layer with a solution containing a fluorine-containing compound and a solvent, followed by drying the solvent, or dry-coating with the fluorine-containing compound obtained by evaporating the solvent from the solution; and a step for curing the fluorine-containing compound to form a water-repellent, oil-repellent layer. The water-repellent, oil-repellent member is obtained by providing, on various substrates, a primer layer of a specific thickness containing, as a main component,an organic silicon compound comprising multiple silanol groups, followed by providing, on the primer layer, a water-repellent, oil-repellent layer of a specific thickness containing, as a main component, the cured fluorine-containing compound according to the abovementioned method. It is thus possible to stably and simply form a water-repellent, oil-repellent coating exhibiting superior abrasion resistance on various substrates, and the primer layer and water-repellent, oil-repellent layer can be applied using a room-temperature (25 degrees centigrade) process.
Description
technical field [0001] The present invention relates to a water and oil repellent member and a method for producing the water and oil repellent member, in particular, to a water and oil repellent with a primer layer formed between a substrate and a water and oil repellent layer using an organosilicon compound having a plurality of silanol groups. A member and a method for manufacturing the waterproof and oil-repellent member. Background technique [0002] In recent years, in order to improve the appearance and visibility, there has been an increasing demand for technology that prevents dirt from adhering and technology that makes dirt easy to fall off. Especially for eyeglass lenses, smart phones, wearable terminals, car navigation, housings of electronic equipment, It is desirable to install a waterproof and oil-proof layer on the surface of the kitchen stove and the body of the conveying equipment because sebum and oil dirt are easy to adhere to. However, the compound hav...
