Description

A kind of high temperature resistance high heat conduction non-viscous paint and its preparation method and application
Technical field
The present invention relates to high-molecular coating technical fields, and in particular to a kind of high temperature resistance high heat conduction non-viscous paint.
Background technique
Non-viscous paint, so that other materials are difficult to adhere on surface, is produced from it since it has low-down surface tension Non-stick pan have since the advent of the world to people life bring great convenience.Non-stick pan is divided into aluminum pot, stainless steel according to substrate Pot, iron pan.The characteristic of aluminum pot is that heat distribution is excellent, and heat-transfer effect is 16 times of stainless-steel pan, and pot body is lighter.But aluminum pot is not easy Oil smoke is big when cleaning, is more with oil.The characteristic of stainless-steel pan is that heat distribution is bad, is also easy to produce heat build-up point and burning foods.Stainless steel Pot pot body weight, not easy cleaning, with oil it is more when easily smolder.Iron-enamel pot heat distribution is bad, bottom of being easily burned.This kind of pot not easy cleaning, Surface is easy breakage, and iron-based material is caused to get rusty.Iron pan heat distribution is bad, is also easy to produce heat build-up point and burning foods, pot body weight, no Easy cleaning is easily got rusty, and with oil it is more when oil smoke it is big.Therefore, current coating non-stick pan is using aluminium or aluminium alloy as pot Base, this is because the good heat conductivity of this metalloid.But the direct contacting foodstuff of aluminum products, how much will affect health.But It is heat build-up point to be easy to cause, to cause to apply since the heat distribution using stainless-steel pan and iron pan as the non-stick pan of substrate is poor Film rupture and burning foods, greatly reduce the service life of coating.
The non-stick pan of existing market mainstream is all the non-viscous paint for relying on surface and spraying a strata fluorine type resin, by it The characteristic of strong-hydrophobicity and low-friction coefficient, to realize what food did not glued, it, which is able to satisfy really in people's cooking process, does not occur Food glue pot requirement, but it there is also many defects.Be first polytetrafluorethylecoatings coatings intensity it is poor, be easy to fall off and Damage, and can soften in cooking process, wood shovel can only be used, harder food can not be cooked;Meanwhile this non-stick pan Also acidic food should not be cooked, otherwise will affect the service life of non-stick pan;Furthermore the use temperature one of polytetrafluorethylecoatings coatings As no more than 250 DEG C, people are difficult to strict control when in use, are easy to damage because of dry combustion method.For polytetrafluorethylecoatings coatings Non-stick pan also always exists dispute with the presence or absence of harm to human health in use, constantly initiation controversial issue;And once Non-viscous paint falls off, and will lead to substantially reducing for non-adhesion behavior.
Polyphenylene sulfide (PPS) is a kind of fire resistant resin binder of excellent combination property.Its crystallinity is high, line expansion is Number is low, at 170 DEG C or less insoluble in any solvent, and has many advantages, such as water imbibition and oil absorption is small, chemical resistance is good.
Chinese patent notification number CN103740192A discloses a kind of fluorine resin coating that graphene is modified, using graphene The intensity of fluorine resin coating is improved, crocking resistance is significantly increased with the adhesive force of substrate, impact resistance, thermal conductivity, The coating have it is at low cost, dosage is few, efficacy lasting, easy to use feature.Although disadvantage is that graphene Addition can be improved into wear-resisting property and thermal conductivity, but high temperature resistant and thermal conductivity still are apparent not enough.
Therefore, need to develop a non-viscous paint required suitable for non-stick pan high temperature resistance high heat conduction to meet modern market Requirement to the field.
