Abstract
The present invention relates to an oil repulsive anti-sticking paint for kitchen ventilators. The paint is prepared by the combination of silicone resin as a superpolymer film-forming agent, silicon rubber as a special addition agent and a filling pigment, xylene as a diluting agent and dimethyl silicon oil as a lubricating agent. A spraying workpiece is baked for half an hour at not too high temperature and then is naturally cooled or cooled in water without causing the deformation of impeller blades. The present invention overcomes the defects of no or poor oil repulsion, no permanence, complicated synthesis technology of raw materials, high energy consumption, low production safety, and the like of the existing similar paint. The paint comprises transparent paint and colored paint.
Description
What the present invention relates to is a kind of coating, concrete is be used for smoke exhaust ventilator scold oil, release coating, belong to technical field of coatings.
Smoke exhaust ventilator is an electrical equipment commonly used in the family life, in the cooking, because animals and plants edible oil volatilization back contacts with smoke exhaust ventilator, make smoke exhaust ventilator, particularly the impeller blade upper surface adheres to the not only sticking but also thick greasy dirt of one deck, and this one deck smeary is removed, in existing life, usually clean bothersome especially and trouble again with artificial.
The raw material that is used for smoke exhaust ventilator coating has multiple, and as external report, the membrane-forming agent based on poly-perfluor alkane ether or poly-fluoroalkane ether has and well scolds oil, repellency energy, and its shortcoming is synthetic difficulty.
Prior art also has the smoke exhaust ventilator that adopts the spraying of powder epoxy coating, and its shortcoming is not scold oil, not antiseized.
Adopt a kind of fluororesin-coated utensil in the prior art in addition, it has easily the characteristics of washing, easily cleaning; But because the synthetic comparatively difficulty of this class monomer, cost is also higher, and is mainly used on the household electrical appliances such as non-stick pan, electric cooker, and this series products has goodish anti-adhesion performance, but not or very poor scolding oiliness and do not glue oiliness arranged.
Antiseized and scold oil or sticking oil, be inequality strictly speaking, antiseized not necessarily sticking oil or scold oil, and scold oil, sticking oil has a good anti-adhesion performance.
If the coating of fluorine resin is used for smoke exhaust ventilator, just not necessarily has and well scold oil, antiseized effect; And the baking temperature of this class coating is usually up to 400 ℃, and the impeller blade that aluminium and alloy thereof are made in the smoke exhaust ventilator is to be out of shape under high like this baking temperature, in addition, adopts this type of coating cost high too, and the roasting plant investment is bigger, big energy-consuming.
In view of having problems in the prior art, the objective of the invention is to overcome the defective of existence, a kind of fine coating of scolding oily anti-adhesion performance that has is provided, bake out temperature is not too high, can not make the impeller blade distortion.
Purpose of the present invention can reach by following technical measures.
Smoke exhaust ventilator contains with scolding oil, release coating: (by W%)

The invention has the advantages that and selected a kind of hydroxy-end capped polydimethylsiloxane to make additive and some kinds of polymkeric substance of compatibility with it, as organic silicone resin, polypropylene provided with hydroxyl group acid esters (F wherein
2" except ^ and the fluorine resin); aminoresin; Synolac etc. are as membrane-forming agent; the former can give these membrane-forming agents and can form and scold filming of oil; add filler pigments again as carbon black; talcum powder, titanium dioxide, zinc oxide, graphite, white carbon black and specialist additive are as hydroxy-end capped polydimethylsiloxane, produce 180 ℃-240 ℃ of baking Wen Gaowei, dry half an hour, just it is lower to form surface energy at substrate surface, to the contact angle of edible oil bigger scold oil, anti-stick coating, the contact angle express liquid to solid avidity greater than capillary degree, contact angle is little, expression profit temp effect is just good, otherwise contact angle is big, promptly hydrophobic, oleophobic property is just good more, contact angle is big, and liquid just can be separated from solid surface more when liquid contacted with solid, also easily more removes from solid surface.Contact angle is greatly one of characteristics of the present invention.Another characteristics of the present invention are that optional membrane-forming agent is more, and raw material sources are wider.Select the different raw materials that can easily buy to reach to produce to have the purpose of scolding anti-the being stained with property coating of oil equally according to the supply-demand situation.Change the requirement that prescription can satisfy different user.
Edible oil volatilization back is not split into the successive oil film on the surface of emerging coating of the present invention, purpose is to be shrunk to diffusing oil droplet soon, along and very easily wipe cleaning, or throw out by the impeller blade of smoke exhaust ventilator, have and well scold oiliness.
Storing temperature is at 180 ℃.
The present invention overcome the similar coating of prior art do not scold oil or scold oiliness very poor, can not be lastingly, defective such as raw material synthesis technique complexity, cost height, power consumption be big.
