Salinization, the water solubility of Lai Shixian resin, while being supplied to the performances such as the certain hardness of resin, solvent resistance and adhesive force；Selection
As the monomer of hydroxy component is provided, the hydroxyl that the dosage by adjusting HEA controls resin contains hydroxy-ethyl acrylate (HEA)
Amount, makes the better crosslinking curing of resin film.Because the monomer of synthetic resin is acrylic monomer, reactivity ratio difference and not bery
Greatly, it is reacted admittedly can once feed intake, obtains water soluble acrylic acid film forming matter；
It is dissolved in ethanol solution Step 2: weighing tetradecanoic acid powder, at the uniform velocity stirs 10min or so with magnetic stirring apparatus,
Until the tetradecanoic acid particle of white is completely dissolved.The tetradecanoic acid ethyl alcohol that 0.1mol/L is added in commercially available nanosized SiO_2 microballoon is molten
It in liquid, is transferred in surface plate after ultrasonic disperse 20min, is placed in 85 DEG C of vacuum oven and dries for 24 hours, room temperature after taking-up
Lower cooling obtains modified Nano SiO2 microballoon；
Step 3: altogether by nanosized SiO_2 microballoon modified and levelling agent, thickener, defoaming agent, mould inhibitor, coalescing agent etc.
With being added in water soluble acrylic acid film forming matter, with the revolving speed grinding 30min of 1000r/s to get the water of addition nanosized SiO_2 microballoon
Property Acrylic Anticorrosive Coatings.
Preferably, methyl methacrylate (MMA) average molecular weight is no more than 2000 in step 1.
Preferably, tetradecanoic acid powder quality is 2.0 ~ 5.0g in step 2, dehydrated alcohol volume is 10 ~ 500ml,
Magnetic stirring apparatus at the uniform velocity mixing speed is not less than 100r/min.
Preferably, levelling agent is organic silicone oil in step 3, thickener is organobentonite, defoaming agent is n-octyl alcohol.
Nanosized SiO_2 hollow microballoon has that density is low, isotropism, corrosion-resistant, good mechanical performance, thermal stability are good, valence
The advantages that lattice are cheap is widely used to the fields such as rubber, plastics, aerospace, pipelines in deep sea heat preservation, hydrogen storage, oil drilling.
Research of the existing part about glass microsphere filling paint at present.The present invention is using water soluble acrylic acid as main film forming substance, innovation
Property micron order nanosized SiO_2 microballoon is added in water soluble acrylic acid film forming matter, it is aqueous to develop a kind of filling of nanosized SiO_2 microballoon
Coating, and systematic Study has been carried out to the performance for the coating prepared.The present invention has functional, safety and environmental protection, synthesis
Simply, cheap advantage.
