Abstract
The invention discloses an exothermic paint capable of absorbing microwaves, which is prepared from the following materials by weight percent: 5-40% of exothermic materials and 60-95% of non-stick coatings. The exothermic paint of the invention is used on products such as ceramics or glass and the like which have penetrability on the microwaves, so that more microwaves are enabled to be absorbed by the exothermic paint when the microwaves heat foods so as to heat the foods by the heat radiation of the ceramics or glass products and the like through the exothermic paint and generate frying and baking functions, so that the cooked foods have the special flavor and mouthfeel of the foods fried and baked in a traditional stove and have better effect on special flavor and mouthfeel as compared with the foods cooked by the traditional stove. When the exothermic paint is applied to the product, the sintering temperature is only 380-460DEG C, and because the sintering is carried out at a low temperature, the loss and change of the exothermic material caused in the high-temperature reaction is avoided, the effect of absorbing the heat radiation of the microwaves is not influenced and the heat radiation is rapidly.
Description
Technical field
The present invention relates to exothermic material, be specifically related to a kind of exothermic paint that can absorb microwave.
Background technology
Microwave oven comes cooking food with microwave, it is by a kind of electronic vacuum pipe---magnetron, produce the ultrashort wave hertzian wave of 2450MHz, by microwave transport element---waveguide, be transmitted in the stove everywhere, by emission, conduction, by food absorption, cause that polar molecule (as water, fat, protein, sugar etc.) in the food is with the hypervelocity vibration of per second 24.5 hundred million times. and make by the caused friction of vibration that food is inner to produce high heat, food is cooked ripe.Microwave can pass insulating material such as glass, pottery, and directly to the food heating, and glass or ceramic ware itself do not generate heat.Because microwave heating and the heating of traditional stove and accessory there are differences, and make the local flavor of cooking food different with mouthfeel, the food shortcoming of microwave oven heating is fried in shallow oil, the roasting mouthfeel that is had.Modern crowd is more and more higher to the requirement of cooking food, approval microwave oven accessibility in use, but dissatisfied to the local flavor and the mouthfeel of institute's cooking food.
Summary of the invention
For addressing the above problem, the invention provides a kind of exothermic paint that can absorb microwave.
Technical scheme of the present invention is: a kind of exothermic paint that can absorb microwave, it is characterized in that, and make by exothermic material 5～40% and non-viscous paint 60～95% by weight percentage.
Described exothermic material is to be made by in Graphite Powder 99, carbonyl iron dust, acetylene carbon black, ferrite powder, the charing silica flour any one or a few.
Described exothermic material is to be made by Graphite Powder 99 70～90%, carbonyl iron dust 10～30% by weight percentage; Or make by acetylene carbon black 70～90%, ferrite powder 10～30% by weight percentage; Or make by acetylene carbon black 20～50%, Graphite Powder 99 50～80% by weight percentage; Or make by carborundum powder 20～40%, Graphite Powder 99 60～80% by weight percentage; Or make by carborundum powder 30～50%, acetylene carbon black 50～70% by weight percentage.
Described non-viscous paint is tetrafluoroethylene non-viscous paint, polyphenylene sulfide non-viscous paint or non-stick polyether sulphone coating.
Non-viscous paint generally is divided into single component or two-pack, and two-pack promptly is made up of base paint and coating materials, when described non-viscous paint is two-pack, selects for use base paint and exothermic material to make exothermic paint.
The present invention also provides a kind of ceramic ware or vierics of energy microwave-absorbing heat-generating, comprises ceramic ware or vierics body, it is characterized in that, is provided with the above-mentioned exothermic paint that can absorb microwave at body surface.
Illustrate exothermic paint production method of the present invention, can produce according to the following steps:
(1) by weight percentage Graphite Powder 99 70～90%, carbonyl iron dust 10～30% are mixed, it is standby to make exothermic material;
(2) it is standby to get non-viscous paint, when described non-viscous paint is two-pack, only selects base paint for use;
(3) by weight percentage that above-mentioned standby exothermic material 5～40% and non-viscous paint 60～95% is mixed, make the exothermic paint that can absorb microwave of the present invention.
Below simply introduce the application of exothermic paint in actual production that can absorb microwave of the present invention, but be not limited thereto:
(1), the exothermic paint that can the absorb microwave outside surface that is sprayed on earthenware porcelain receptacle forms the heating coating, heating coat-thickness is 0.3～3mm, and the earthenware porcelain receptacle that will be provided with the coating of generating heat sent into the kiln drying 10～30 minutes, drying temperature is 80～200 ℃;
(2) if exothermic paint is to adopt the base paint allotment of two-pack non-viscous paint to form, then can add the coating materials of spray two-pack non-viscous paint to the earthenware porcelain receptacle that has been provided with heating coating and drying in the above-mentioned steps (1); Coating materials evenly is sprayed on the heating coating that the earthenware porcelain receptacle outside surface has been provided with, and the coating materials coating is 0.05～0.1mm, and earthenware porcelain receptacle was sent into the kiln drying 5～30 minutes, and drying temperature is 80～200 ℃; This step is not a steps necessary;
(3), with above-mentioned finish the spraying and the exsiccant earthenware porcelain receptacle send into the kiln sintering, sintering temperature is 380～460 ℃, sintering time is 20～60 minutes, can absorb the formed heating coating of exothermic paint of microwave through agglomerating earthenware porcelain receptacle outside surface firm attachment.
Put into chicken block in the earthenware porcelain receptacle that above-mentioned sintering is made, add an amount of edible oil, earthenware porcelain receptacle is put into microwave oven together with food cook, the chicken block that makes has the local flavor of baking.Earthenware porcelain receptacle in use, the heating coating of outside surface can microwave-absorbing heat-generating, and with the food of heat transferred earthenware porcelain receptacle inner face.After earthenware porcelain receptacle used, the coating of outside surface did not have damage, can reuse.
Exothermic paint use of the present invention is had on the product of penetrance microwave at pottery or glass etc., can make microwave in to the food heating, more by heating that exothermic paint absorbs, to realize that pottery or glassy product etc. generate heat by exothermic paint, thereby food is heated, generation fries in shallow oil, roasting effect, and the food of being cooked has that traditional stove and accessory is fried in shallow oil, the local flavor of roast food and mouthfeel, and food local flavor and mouthfeel are better than the effect of the traditional stove and accessory cooking.Exothermic paint of the present invention is in being applied to the process of product, sintering temperature only needs 380～460 ℃, and owing to be low-temperature sintering, loss and the variation of having avoided its exothermic material in pyroreaction, to cause, do not influence the effect of its microwave-absorbing heat-generating, heating rapidly.
