Description
Technical field
The present invention relates to electric heating appliance technical fields, and in particular to a kind of non-sticking lining and preparation method thereof and cookware and
It cooks equipment.
Background technique
Existing non-sticking lining is mainly Teflon class PTFE non-sticking lining or ceramic non-stick coating, and these types of coating is normal
The molding mode of rule is all and this coating life using air pressure spraying, high temperature sintering solidifies again after electrostatic spraying
Generally only half a year arrives one-year age, and coating hardness is low that (Vickers hardness of PTFE non-sticking lining is 100-200HV, ceramic
The Vickers hardness of non-sticking lining is 200-350HV), coating adhesion is small, and (binding force of PTFE non-sticking lining is 2-10MPa, pottery
The binding force of porcelain non-sticking lining is 2-5MPa), coating layer thickness it is smaller (PTFE non-sticking lining with a thickness of 20-50 μm, ceramic non-stick
Coating with a thickness of 20-40 μm), acid and alkali-resistance and salt resistant character it is also general, in the long-term use inevitably scrape, grind
Damage, corrosion and lead to coating shedding, failure, and after surface covering failure, this non-sticking lining will be without non-stick, this
Service life and application to coating cause and significantly limit.
Existing cooking apparatus, including frying pan, electric cooker, inner tub of pressure cooker etc. use non-sticking lining on a large scale, and mention
The critical issue of cooker industry is had become for a kind of coating for persistently not gluing, and haveing excellent performance.
Summary of the invention
The purpose of the invention is to overcome the above problem of the existing technology, a kind of non-sticking lining and its preparation are provided
Method and cookware and equipment of cooking, the non-sticking lining have surface hardness height, coating binding force high and hydrophobic non-stick good
The advantages that.
In order to improve the performance of non-sticking lining, raw material and forming method for non-sticking lining carry out the present inventor
A large amount of research is found in research, for two kinds of materials of ceramic powders and fluorine-containing resin powder, each have their own advantage,
It will be expected to improve the resultant effect of non-sticking lining if can be combined together the two and prepare non-sticking lining, be set out based on this
Point, inventor have carried out a large amount of research again, find that the fusing point of fluorine-containing Resin materials is lower in research, in case of heating
Be easy atomization, and when fluorine-containing Resin materials atomization after so that ceramic particle melt drip across fluorine-containing Resin materials aerosol again
When striking matrix surface, it is capable of forming with the coated particle of fluorine-containing Resin materials coating ceramic particle.By this coated particle
Being formed by settled layer (non-sticking lining of the present invention) has preferable hardness because including ceramic particle in coated particle,
And there is good functional characteristic because the surface in coated particle is coated with fluorine-containing Resin materials, such as hydrophobic (painting non-stick
Layer surface wetting angle is big)；Simultaneously because using plasma spraying it is this it is special by the way of form non-sticking lining, be conducive to substantially
Degree improves the bond strength of non-sticking lining；Furthermore non-sticky coating can also be improved simultaneously in conjunction with specific equipment and special process
Scraping and wiping resistance performance, corrosion resistance, coating compactness (porosity is low) and service life.
Therefore, to achieve the goals above, one aspect of the present invention provides a kind of method for preparing non-sticking lining, this method
Include:
(1) matrix is pre-processed；
(2) matrix surface for obtaining step (1) carries out optional the pre-heat treatment；
(3) it using ceramic powders and fluorine-containing resin powder as raw material, is handled by plasma spraying, is formed not in matrix surface
Adhesive coating layer；
Wherein, in the step of plasma spraying is handled, the flame stream formed using plasma gun, and formed
Flame stream in ceramic powders are sent at lance outlet D1, the fluorine-containing resin powder of feeding apart from lance outlet D2 at, wherein D2
Greater than D1.
Second aspect of the present invention provides the non-sticking lining that the method for the invention is prepared.
Third aspect present invention provides a kind of cookware, which includes matrix and the non-sticking lining that is formed on matrix,
The non-sticking lining is the stack layer of the particulate matter with flat structure and the particulate matter includes ceramic particle core and fluorine-containing
Resin materials clad.
Fourth aspect present invention provides one kind and cooks equipment, which includes cookware of the present invention.
The method for preparing non-sticking lining of the invention by by ceramic powders and fluorine-containing resin powder in plasma spray gun-shaped
At the different location of flame stream feed intake so that the drop of melting of ceramic particle strikes again across the aerosol of fluorine-containing Resin materials
Matrix surface, and then the particulate matter of fluorine-containing Resin materials coating ceramic particle is formed, and the accumulation based on these particulate matters is formed
The present invention glues non-sticking lining；And it is formed by non-sticking lining by this method and has the following beneficial effects:
1) in being formed by non-sticking lining, contain ceramic particle and fluorine-containing Resin materials, Jin Ertong in particulate matter simultaneously
When ensure that the hardness of non-sticking lining and hydrophobic non-stick；
2) it is formed by plasma spraying in the process (i.e. the banking process of molten particles) of coating, is all between each particle
Molten condition links together, thus coating fine and close (porosity is small), interparticle combination are very firm (binding force is high)；It does not glue
Mechanical bond is formed in rough surface by the molten particles of high speed between coating and matrix, much higher than being sintered after aerial spraying
At anchoring strength of coating；
3) in being formed by non-sticking lining, particulate matter has the structure of fluorine resin material coating ceramic particle, this makes
Obtaining the non-sticking lining has preferable scraping and wiping resistance performance, corrosion resistance, and then is conducive to extend the service life of non-sticking lining
It is long；
4) being formed by non-sticking lining is to be accumulated to be formed by the flat particulate matter with clad structure, this institute's shape just made
