Background technology
Such as the radiating subassembly such as metal fin and heat pipe, radiating effect is no doubt good, but expensive and be not suitable for the product design of light and handyization, thereby has development and the application of heat radiation coating.But, existing heat radiation coating solidify to form after heat dissipating layer in radiating surface, not good because of the resistance to crocking such as weathering resistance, thermotolerance, lower temperature resistance and chemical proofing of the base-material that uses, cause the thermal diffusivity of the heat dissipating layer of institute's shape after solidifying easily to reduce because pollutent adheres to; Moreover the filler that existing heat radiation coating uses is not because having pore texture, therefore the thermal diffusivity that can represent is not high.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcomes the above-mentioned defect that prior art exists, and kind of nanometer heat radiation coating and a preparation method are provided, and effect that it has the good and high-cooling property of resistance to crocking, also has effect that the uniform filling of being beneficial to is disperseed.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of nanometer heat radiation coating constitutional features, is the filler taking fluorocarbon resin as base-material mixes with pore texture, and the weight ratio of this base-material and this filler is 3 to 5 times.
In addition, this filler is selected from the combination of bamboo charcoal nano, CNT (carbon nano-tube), nano zine oxide, nano oxidized germanium or aforementioned filler; The mixed solvent of this base-material and this filler is selected from the combination of thinner, vinyl acetic monomer, dehydrated alcohol, distilled water or aforementioned mixed solvent; The weight ratio of this base-material and mixed solvent is 0.9 to 1.4 times, and the weight ratio of this filler and mixed solvent is 0.3 to 0.6 times.
Nanometer heat radiation coating preparation method of the present invention, comprises the following steps: that a. is dissolved in fluorocarbon resin in mixed solvent as base-material, and obtains base-material mixed solution; B. the filler with pore texture that by weight ratio is 0.2 to 0.33 times of this base-material is dissolved in mixed solvent, and obtains filler mixed solution; C. the base-material mixed solution obtaining through step a and the filler mixed solution obtaining through step b are filtered; And d. is uniformly mixed base-material mixed solution and filler mixed solution after step c filters.
But the base-material of step a and the weight ratio of mixed solvent are 0.9 to 1.4 times, the filler of step b and the weight ratio of mixed solvent are 0.3 to 0.6 times, and step c utilizes 350 eye mesh screens to filter, and steps d utilizes emulsification pretreatment machine high-speed stirring to mix.
The invention has the beneficial effects as follows that effect that it has the good and high-cooling property of resistance to crocking also has effect that the uniform filling of being beneficial to is disperseed.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is nanometer heat radiation coating preparation method's of the present invention process flow chart.
Fig. 2 is the electron microscope picture of nanometer heat radiation coating of the present invention.
Embodiment
First, refer to shown in " Fig. 1 ", nanometer heat radiation coating preparation method of the present invention, comprises the following steps: that a. is dissolved in fluorocarbon resin in mixed solvent as base-material, and obtains base-material mixed solution, and to make the weight ratio of base-material and mixed solvent be 0.9 to 1.4 times; B. the filler with pore texture that by weight ratio is 0.2 to 0.33 times of this base-material is dissolved in mixed solvent, and obtains filler mixed solution, and to make the weight ratio of filler and mixed solvent be 0.3 to 0.6 times; C. utilize 350 eye mesh screens to filter the base-material mixed solution obtaining through step a and the filler mixed solution obtaining through step b; And d. utilizes emulsification pretreatment machine high-speed stirring to mix with filler mixed solution the base-material mixed solution after step c filters.
Moreover, nanometer heat radiation coating the first embodiment of the present invention, that 120g fluorocarbon resin is dissolved in and in 120g ethyl acetate, obtains base-material mixed solution, separately 30g bamboo charcoal nano is dissolved in and in 80g dehydrated alcohol, obtains filler mixed solution, and filter this base-material mixed solution and this filler mixed solution with 350 eye mesh screens, then use this base-material mixed solution of emulsification pretreatment machine high-speed stirring and this filler mixed solution 10 minutes, and mix as nanometer heat radiation coating (consulting shown in " Fig. 2 ").
Another person, nanometer heat radiation coating the second embodiment of the present invention, that 120g fluorocarbon resin is dissolved in and in 100g thinner, obtains base-material mixed solution, separately 30g bamboo charcoal nano is dissolved in and in 60g ethyl acetate, obtains filler mixed solution, and filter this base-material mixed solution and this filler mixed solution with 350 eye mesh screens, then use this base-material mixed solution of emulsification pretreatment machine high-speed stirring and this filler mixed solution 10 minutes, and mix as nanometer heat radiation coating.
