Edge, addition water soluble solid agent realize solidification and film forming, can have adhesive force, water resistance and the insulating properties of some strength.
But by comparative example 1 it is found that only adding above-mentioned component can not achieve satisfactory water resistance and insulating properties effect, therefore Shen
It asks someone through repetition test, discovery is added to natural rubber latex, bacteria cellulose, and colloidal silicon dioxide is preparing aqueous acrylamide
Synergistic effect is played in acid resin anti-corrosive insulation coating.
Speculate that its possible mechanism is that natural rubber latex has good film forming and ductility, it can be quickly in conductive steel
On piece film forming promotes the film forming and integrality of water-based acrylic resin, and has good dispersibility, disperse bacterial fiber
Element and colloidal silicon dioxide, enhance the integral strength of paint film, to enhance water resistance, and can on uniform fold on steel disc,
Realize uniform insulating properties, leakproof；Bacteria cellulose is combined into 40-60 nanometers of thick fibers by 3-4 nanometers of diameter of fento
Beam, and it is intertwined to form flourishing hyperfine network structure, it is covered on conductive steel disc surface and forms good hydrophobic structure, with
Caoutchouc latex adds together, and so as to uniform fold on conductive steel disc surface, huge specific surface area can be good
Fitting steel disc each face, further increase waterproof effect and insulation effect；Colloidal silicon dioxide dispersion can be filled into thin
In the network structure of bacterium fiber, the insulating properties of the sealant of formation is greatly improved, and nanostructure is in surface of the paint film
It can be realized super-drainage structure in layer, further increase waterproofness, there is good dispersibility in caoutchouc latex, from
And can be realized that it is evenly dispersed in bacteria cellulose, the mechanical property and globality of paint film are greatly improved, waterproof is improved
Property.
(3) by the data of comparative example 6-8 as it can be seen that natural rubber latex, bacteria cellulose, the weight ratio of colloidal silicon dioxide
Not at (2-4): (6-8): when in (1-3) range, the waterproofness of coating obtained and the numerical value of insulating properties numerical value and embodiment 1-3
It is very different, it is suitable with the numerical value of the prior art (comparative example 5) much smaller than the numerical value of embodiment 1-3.Natural rubber latex of the present invention
Cream, bacteria cellulose, for colloidal silicon dioxide as reinforcement system, it is exhausted that embodiment 1-3 control prepares water-based acrylic resin antirust
By addition natural rubber latex when edge coating, bacteria cellulose, the weight ratio of colloidal silicon dioxide is (2-4): (6-8): (1-
3), realize that there is good film forming and ductility using natural rubber latex in reinforcement system, it can be quickly in conductive steel
On piece film forming, promotes the film forming and integrality of water-based acrylic resin；Bacteria cellulose adds together with caoutchouc latex,
Can uniform fold on conductive steel disc surface, further increase waterproof effect and insulation effect；Colloidal silicon dioxide dispersion, can
It is filled into the network structure of bacterial fibers, the insulating properties of the sealant of formation is greatly improved, so that natural rubber
Latex, bacteria cellulose, the reinforcement system that colloidal silicon dioxide is constituted are applied in water-based acrylic resin anti-corrosive insulation of the invention
In material, collaboration improves the water resistance and insulating properties of water-based acrylic resin anti-corrosive insulation coating.
The above content is it cannot be assumed that present invention specific implementation is only limited to these instructions, for the technical field of the invention
Those of ordinary skill for, under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all answers
When being considered as belonging to present invention scope of patent protection determined by the appended claims.
