Embodiment approach

[0108] According to one embodiment of the present invention, the CCC is a sol-gel CCC comprising:

[0109](a) 11wt% to 20wt% of silane or its oligomers as a binder;

[0110] (b) 19.5wt% - 41.5wt% silica mixture;

[0111] (c) 0~19wt% functional filler;

[0112] (d) 2wt%-15wt% ceramic powder emitting far-infrared radiation and anions; and

[0113] (e) 0 to 25% by weight of pigments that produce color;

[0114] where wt% is compared to the total weight of the sol-gel CCC.

[0115] In a particularly advantageous embodiment, said sol-gel CCC as envisaged herein comprises:

[0116] (a) 11wt% to 20wt% of silane or its oligomers as a binder;

[0117] (b) 19.5wt% - 41.5wt% silica mixture;

[0118] (c) 3wt% to 19wt% functional filler; for example 3wt% to 15wt% or 10wt% to 19wt% functional filler;

[0119] (d) 2wt%-15wt% ceramic powder emitting far-infrared radiation and anions; and

[0120] (e) 0 to 25% by weight of pigments that produce color;

[0121] where wt% is compared to...

Embodiment 1

[0260] The aluminum substrate surface of the artefact was roughened by grit blasting to increase the surface area on which the aluminum oxide to be subsequently deposited was firmly attached. After roughening, washing and drying steps are performed to remove contamination from blasting. After the washing and drying steps, an anodizing step is performed to form a protective aluminum oxide film layer with enhanced anti-corrosion and anti-wear properties. After anodization, the application step of the enhanced ceramic coating ECC composition is carried out. The ECC composition comprises a mixture of a ceramic coating composition (CCC) and a diamond additive (DA).

[0261] The CCC comprises a blend of the following materials: 40-50 wt% binder, which is 34 wt% silane in ethanol or an oligomer derived therefrom as binder; 27-34 wt% chemically bonded Silicon dioxide mixture of said silane or oligomer derived therefrom as binder and containing 20% ​​to 40% by weight of a mixture of ...

Embodiment 2

[0263] The stainless steel substrate surface of the artifact was roughened by grit blasting to increase the surface area for application of other layers. After roughening, washing and drying steps are performed to remove contamination from blasting. After said washing and drying steps, a step of applying said enhanced ceramic coating ECC composition is performed. The ECC composition comprised a mixture of a ceramic coating composition (CCC) as described in Example 1 and a diamond additive (DA). After the step of applying the ECC composition is completed, a step of drying at 280-320° C. for 7-10 minutes is performed to form a dry film coated on the artifact. The coated artefact has the combined advantages of being non-stick, scratch-resistant and abrasion-resistant.

Abstract

The present invention relates to an enhanced ceramic coating, ECC, composition comprising a non-stick ceramic coating composition, CCC, and 0.2 wt% - 2 wt % diamond additive, DA with wt% compared withthe total weight compared to the ECC composition. It also relates to a method of coating an artefact with the ECC, and an artefact provided 5 with a dry film coating containing an ECC prepared usingan ECC composition of the invention. An artefact coated with the ECC has the combined advantages of durable non- stick, scratch resistance and abrasion resistance.

Description

technical field [0001] The present invention relates to enhanced ceramic coatings and enhanced ceramic coating compositions for artefacts which, in addition to improved hardness, wear and scratch resistance, also provide Durable (durable) and long-lasting (long-lasting) non-stick. The invention also relates to artefacts coated with reinforced ceramic coatings. The invention also relates to the use of reinforced ceramic coatings for coating artefacts, eg cookware items. Background technique [0002] Non-stick coatings have many applications, for example, cookware such as pots, pans and cooking utensils, and heaters of various types (for example, wood burning stoves, heating boilers, infrared heaters, etc.), fans, refrigerators, irons, building materials, health aids, personal care products such as hair straighteners, curling irons, and industrial products. One problem in the art is that coatings for cookware need to withstand surface abrasion and scratching and exposure to...
