Description
Technical field
The invention belongs to fields of home appliance technology, and in particular to a kind of household electrical appliances coating and preparation method thereof.
Background technique
The development of science and technology is that people bring the life of high quality, and various domestic electric appliances are brought to people's lives
While convenient, a dangerous stealthy pollution sources-electromagnetic radiation invades also quietly and penetrates into the side of people's life
Our health is gradually endangered in aspect face.Know from physics common sense, any electric appliance be electrified stream will generate electromagnetic field or
Common air-conditioning, television set, computer, micro-wave oven, humidifier, air cleaner, electric blanket are arrived greatly in electromagnetic radiation；It is small to arrive daylight
The household electrical appliance such as lamp, hair dryer, mobile phone, charger even power outlet, switchboard, wiring insert row can all generate electromagnetic radiation.
Even if the electromagnetic field least to attract attention may also cause the symptoms such as stress, headache, depression and insomnia, lead to immunity degradation,
Greatly improve the disease incidence of various diseases.Therefore, a kind of radiation shielding coating of household electrical appliance is developed to reduce or slow down radiation
Influence to human health is this field technical issues that need to address.The Chinese invention of Publication No. CN104789004A is special
Benefit, discloses a kind of radiation shielding coating for electric appliance, in the raw material of the coating and is not added with to have and is obviously improved anti-radiation performance
The ingredient of energy.
Due to the effect of phase mutual friction between household electrical appliance and other objects, it is easy to produce accumulation of static electricity, electrostatic hazard occurs,
The normal use of household electrical appliance is such as influenced, can discharge generate spark in severe cases, is set off an explosion and fire.So opening
The antistatic coating for sending out household electrical appliance a kind of is this field technical issues that need to address.Antistatic coating be divided into Intrinsical and
Addition type two major classes, Intrinsical antistatic coating technology is still immature, and the antistatic coating largely used at present is addition type painting
Material.Addition type coating is the function of adding certain conductive coating in nonconducting binder resin to realize static conductive, only
The degree that the volume fraction of conductive filler reaches certain could form conductive network or access, embody conductive property.At present
Common conductive filler has: Carbon materials (carbon black, graphite etc.), metal powder (silver powder, copper powder), metal oxide semiconductor
(tin oxide, iron oxide, zinc oxide), conducting nanoparticles and antistatic auxiliary agent etc..Wherein metal powder density is big, is formed conductive
Access needs biggish volume fraction, and surface layer is oxidizable, electric conductivity, and poor corrosion resistance can be reduced or even lose, thus shadow
Other performances of coating are rung, therefore metal powder is subject to certain restrictions as the application of conductive filler；It is antistatic agent temperature tolerance, resistance to
Aqueous, oil resistivity, corrosion resistance, durability are poor, and antistatic property is unstable；Early stage antistatic coating generally uses Carbon materials
As conductive filler, black conductive graphite and carbon black dispersion are poor, and product color is black, it is not easy to be modulated to other shallower face
Color；With the development of science and technology, having gradually appeared the novel conductive fillers such as metal oxide semiconductor and nanometer conductive powder, and anti-
It is applied in electrostatic figure layer, this kind of material color is shallow, is easy to mix colours, and enriches the colour system of antistatic coating, but this kind of
Additive amount is big when coating is used alone, and dispersion stabilization is poor, will affect the performance of coating.Publication No. CN106221501A's
Chinese invention patent discloses a kind of electric fan antistatic coating, and the antistatic property of the coating is not obviously improved.

There are stable dispersibility and good compatibility in base-material resin aqueous emulsion, it is logical stable conduction can be formed in coating surface
Road increases coating to the absorption loss of electromagnetic wave, the reflection loss to electromagnetic wave is reduced, to reduce electromagnetic wave to environment
Caused by secondary pollution.
(3) coalescing agent of coating of the present invention uses Lauryl Alcohol ester, and Lauryl Alcohol ester is practically insoluble in water, Bu Huisui
The variation of ambient humidity the phenomenon that generating whiting, and small toxicity, nonflammable, hydrolytic stability is good, and volatility is lower, can have
Effect reduces the film-forming temperature of resin aqueous emulsion.
(4) coupling agent of coating of the present invention uses metatitanic acid value coupling agent YB-401, since the present invention is using aqueous
For resin emulsion as substrate, solvent is few, and lubricity is low, thus adhesive force is weaker, forms bridge between metatitanic acid value coupling agent and ground
Key is improved due to introducing polar group in coupling agent with the compatibility of ground, thus adhesive force is obviously improved.
