Embodiment 1
[0043] Example 1, see figure 1 . The present embodiment is a preferred embodiment, that is, a kind of matt nano-silica modified hard wood wax oil, the raw materials it includes and its weight percent content are:
[0044] Hard tung oil or linseed oil 36%,
[0045] Carnauba wax with a softening point between 85°C and 95°C
[0046] 17%,
[0047] The oil length is 78%-80%, and the solid content is more than 98% of linseed oil long oil alkyd resin
[0048] 17%,
[0049] Nano silica 3% with a particle size between 60-80nm,
[0050] Aromatic hydrocarbons with a distillation range between 160-200° 25.0%
[0051] Isooctanoate compound drier 1.7%,
[0052] Methyl ethyl ketone oxime 0.3%.
[0053] The performance comparison table between this product and ordinary wood wax oil / nitro paint / polyurethane paint figure 1 .
Embodiment 2
[0054] Example 2, see figure 2 . The method for making product of the present invention comprises the following steps:
[0055] The first step is to prepare material A:
[0056] (1) The hard tung oil that is 36% by weight percentage content is added to reactor, after keeping 30-60 minute in the scope of 280 °-290 ℃ of temperature, when testing viscosity in the scope of 6-10Pa.s, rapidly cool down to Below 180℃;
[0057] (2) When the temperature drops to 115°-125° C., add decyclic aromatic hydrocarbons with a weight percentage content of 12%, and add carnauba wax with a weight percentage content of 17%, and cool down and leave the kettle after the dissolution is complete;
[0058] The second step is to prepare material B:
[0059] (1) the linseed oil long oleoresin that the weight percent content is 17% joins in the high-speed disperser;
[0060] (2) In the above-mentioned high-speed disperser, adding a decyclic aromatic hydrocarbon with a weight percent content of 13% is...
