Embodiment 1

[0052] The cooker provided by this embodiment, such as figure 1 , 2 As shown, the cooking utensil base 4 is included, the inner surface of the cooking utensil base is attached with an intermediate bonding layer 3, and the surface of the intermediate bonding layer 3 is attached with a non-stick coating.

[0053] Wherein, the intermediate bonding layer can be attached to the inner surface of the cookware base by an anodic oxidation process, but is preferably attached to the inner surface of the cooker base by a thermal spraying process or a hard anodic oxidation process.

[0054] Wherein, the material of the cooker base is aluminum alloy, stainless steel or ceramic material; the material of the intermediate bonding layer is alumina, zirconia or titanium oxide; the thickness of the intermediate bonding layer attached by anodic oxidation process is 2 μm to 5 μm, The thickness range of the intermediate bonding layer attached by thermal spraying process or hard anodizing process i...

Embodiment 2

[0078] This embodiment provides a method for manufacturing a cooker, comprising the steps of:

[0079] S10 cooking utensil matrix forming;

[0080] S20 attaching an intermediate bonding layer on the surface of the cookware base through a thermal spraying process;

[0081] Among them, before spraying, it is necessary to carry out a series of pretreatments on the cookware substrate to improve the bonding force between the coating and the cookware substrate. Degreasing treatment Clean the grease on the surface of the substrate, clean the dirt and dust on the surface of the metal substrate; use 60-100# alumina sand to evenly sandblast the substrate to make the roughness Ra of the substrate reach 2-3.5μm.

[0082] Described thermal spraying process (also referred to as plasma spraying process) parameter condition is: spraying distance is 120mm; Spraying power is 35Kw; Main gas is Ar, and gas flow rate is 46L / min; Secondary gas is H2, and gas flow rate is 4.3L / min; the powder fee...

Embodiment 3

[0099] Compared with adopting the method described in Example 2 to prepare the cooker, the difference is: the electrostatic spray gun mode is used to prepare the undercoat and the top coat; wherein, the non-stick resin of the undercoat and the top coat is PFA (soluble polytetrafluoroethylene vinyl fluoride).

[0100] The method of electrostatic spraying is adopted, and the auxiliary material is compressed air, which requires clean and dry, oil-free and water-free [moisture content less than 1.3g / m 3 , oil content less than 1.0×10 -5 % (mass fraction)], the specific process parameters of its spraying are as follows: electrostatic high voltage: 20-50kV; electrostatic current: 10-20μA; flow rate pressure: 0.30-0.55MPa; atomization pressure: 0.30-0.45MPa; MPa; fluidization pressure of powder supply barrel: 0.04-0.10MPa; distance from spray gun mouth to workpiece: 150-300mm; conveyor chain speed: 4.5-5.5m / min; thickness of electrostatic spraying is controlled at 30-80μm.

Abstract

The invention relates to a cooker and a manufacturing method of the cooker. The cooker comprises a base body of the cooker, wherein a middle bonding layer attaches to the inner surface of the base body of the cooker, and a non-adhesive coating attaches to the surface of the middle bonding layer. The cooker provided by the invention has the advantages that the hardness is high, the corrosion resistance is strong, the abrasion resistance is good, and the non-adhesive coating is good in bonding force.

Description

technical field [0001] The invention relates to a cooker and a preparation method thereof, belonging to the technical field of cooker preparation. Background technique [0002] In order to prevent the rice from sticking to the bottom of the pot, the existing electric rice cooker and electric pressure cooker usually spray a non-stick coating on the inner surface of the inner pot, but the adhesion between the non-stick coating and the base of the inner pot is usually not strong enough to make it wear-resistant Poor performance, easy to fall off from the base of the inner pot. The inventor has done an experiment and rubbed the inner pot sprayed with a non-stick coating with a 3M scouring pad. After rubbing less than 2000 times, the non-stick coating will fall off from the base of the inner pot, exposing the aluminum-based pot. With matrix, harmful to human health. [0003] In addition, good water quality is also one of the key factors for cooking a pot of good rice. People ge...
