Abstract
The invention discloses a material with a specific surface structure for preparing a non-sticky pan. The lower surface of the material is planar, the upper surface of the material is concave-convex and is formed by the regular arraying of micron-sized hemispheres in an HCP (hexagonal close packed) manner, and nano-sized hemispheres are respectively distributed on the surface of each micron-sized hemisphere. By adopting the specific surface structure, the material can realize the non-sticky effect, thereby fundamentally avoiding damage and pollution to human beings and the environment by a harmful component namely PFOA (perfluorocaprylic acid) in Teflon used at present for producing the non-sticky pan.
Description
Technical field
The present invention relates to a kind of material, in particular for the material with specific surface structure of preparation non-stick pan with specific surface structure.
Background technology
Since this product of non-stick pan came out, its " health " just enjoyed people's attention always.Why non-stick pan in the market can cannot not realized stickingly, mainly is to rely on the coating of that one deck in the bottom of a pan " Teflon ".This material is the general name of fluorine resin, comprises polytetrafluoroethylene (PTFE), perfluoroethylene-propylene and various fluorinated copolymer.Perfluorooctanoic acid (PFOA) is the necessary additive in the process of production Teflon, after the PFOA that chemical property is stable enters natural environment and human body, and meeting long-term existence, rather than very fast decomposition.Studies show that low dosage PFOA not only appears in river, ocean and the soil, also is present in people's the blood.Because this artificial compound has been proved carcinogenesis and other adverse consequences in zoopery, if extensively be present in natural environment and the human body, its consequence is then hardly imaginable.In order to reduce existing non-stick pan product to the potential harm of human body, countries in the world begin to take appropriate measures one after another.Environmental Protection Agency (EPA) is maked decision, and orders 8 tame chemical companies such as du pont company to gradually reduce and makes the required nucleus PFOA of teflon coating until stopping using.According to the EPA requirement, to cut down 95% PFOA use amount in 2010, will be forbidden by 2015 comprehensively.China national health department has also formulated the relevant security of standard to guarantee that non-stick pan uses.This standard makes non-stick pan and has been used as two restrictions, and the one, non-stick pan can not be made acid food, and two are to use temperature will be limited in below 250 ℃.Yet only depend on limit production not tackle the problem at its root, change the existing traditional preparation process method of utilizing immersion coating cannot not realize stickingly effect and be only long-term plan.Therefore, has potential development space by designing the non-stick pan material that special material surface structure prepares environmental protection.
Summary of the invention
The purpose of this invention is to provide a kind of material that is used to prepare non-stick pan that health is not had harm with specific surface structure.
The material that is used to prepare non-stick pan of the present invention with specific surface structure, its lower surface is the plane, upper surface is to arrange the male and fomale(M﹠F) that forms by micron-sized hemisphere according to the formal rule of six side's solid matters, and each micron order hemisphere surface is evenly equipped with nano level hemisphere.
The above-mentioned material with specific surface structure can be that metal or alloy is prepared from by mold pressing, and general, the diameter of micron-sized hemisphere is 30 μ m, and nano level hemisphere diameter is 250nm.
This material is because the surface has hemispherical projection, when water or other material contact with material surface, the hemispherical structure of uniform nanoscale can be avoided the mutual reunion between water or other material effectively, and can guaranteeing water or other material, the micron order hemisphere that is six side's solid matters can not enter in the space between micron ball, connected mutually by besieging air bolus in the space between each projection, thereby on entire contact surface, form an air layer that is interconnected, the existence of this air layer has overcome the self gravitation of water or other material, produce a surface action power that makes progress perpendicular to material surface and direction, therefore can stop water or other material to contact effectively with the pot surface, thereby reached the effect of " not sticking ", this material with specific surface structure can be used for preparing on a large scale non-stick pan.
Beneficial effect of the present invention is:
The effect that the present invention can cannot not realize stickingly by the ad hoc structure of material surface, harm and the pollution of fundamentally having avoided the harmful components perfluorooctanoic acid (PFOA) in " Teflon " that existing production non-stick pan coating layer uses that human and environment are caused.
Description of drawings
Fig. 1 is the side view with material of specific surface structure.
The specific embodiment
With reference to Fig. 1, the material that is used to prepare non-stick pan of the present invention with specific surface structure, its lower surface is the plane, upper surface be by micron-sized hemisphere 1 according to the regularly arranged male and fomale(M﹠F) that forms of six side's solid matters (hcp), each micron order hemisphere surface is evenly equipped with nano level hemisphere 2.
Claims (1)
1. be used to prepare the material with ad hoc structure of non-stick pan, the lower surface that it is characterized in that this material is the plane, upper surface be by micron-sized hemisphere (1) according to the regularly arranged male and fomale(M﹠F) that forms of six side's solid matters, each micron order hemisphere surface is evenly equipped with nano level hemisphere (2).
