Technical field
The present invention relates to wood wax oil fields, specifically, being related to a kind of environmental protection electrostatic spary coating type wood wax oil and preparation method thereof
And application.
Background technology
Wood wax oil, which is that vegetable oil Wax coatings are domestic, to be commonly called as, and is a kind of similar natural woodenware painted and be different from paint
Coating.It and that paint for being produced based on petrochemical industry class synthetic resin is entirely different at present, raw material mainly with refine linseed oil,
The crude vegetals such as palm wax and vegetable wax simultaneously coordinate some other natural component to merge.Since oil can penetrate into timber
Portion carries out deep layer to timber and moistens maintenance;Wax can combine closely with lumber fibre, enhancing case hardness, water proof anti-soil, therefore,
Wood wax oil can provide most outstanding beautification and protective effect.
Remain able to detect in part haze tallow oil product on the market at present the Elements in Organic Solvents such as toluene, dimethylbenzene with
And heavy metal, or it is added with chemical naval stores, it is not truly realized materials safety, environmental protection;And there is also product gloss
Difference, hardness is low, wearability and film forming are poor, it is incompatible between each ingredient caused by product stability it is poor the problems such as.In addition, at present
Do not occur also can be used for the wood wax oil of electrostatic spraying in the market, and wood wax oil can be significantly reduced using the spraying of electrostatic spraying form
Cost and drying time.
Therefore, it still needs to research and develop a kind of suitable for electrostatic spraying, environmental protection and the wood with performances such as excellent abrasive resistance, stability
Wax oil.
