The consistency and hardness of paint film, and then improve a variety of physical resistances of paint film, thus the product have excellent water resistance and
The characteristics of high adhesion force, has a vast market foreground.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of bi-component acrylic cover lotions, are used as A
Component and polyisocyanate (B component) mixed paint film, when there is extremely strong water resistance and high adhesive force, and having open
Between it is long, easily construction the advantages that.The present invention goes back while providing the preparation method of above-mentioned bi-component acrylic cover lotion.
To achieve the goals above, a kind of bi-component acrylic cover lotion that the present invention uses, by weight percentage,
Including following raw material: hydroxy-ethyl acrylate 0.8~1.5%, A-1740.5~1.5%, n-dodecyl mercaptan 0.08~
0.12%, methyl methacrylate 22~25%, acrylic acid 0.7~0.9%, Isooctyl acrylate monomer 2~5%, butyl acrylate
12~14%, anion emulsifier EPA-073 0.5~0.8%, nonionic emulsifier LCN118 0.3~0.5%, Sol dimension
Sodium-salt type anion emulsifier CM300.1~0.3%, initiator 0.1%~0.3%, oxidant 0.1~0.2%, reducing agent
0.1~0.2%, the deionized water of pH adjusting agent 0.5~1%, surplus adds to 100%.
The initiator is ammonium persulfate.
The oxidant is tert-butyl hydroperoxide；The reducing agent is VC.
The pH adjusting agent is ammonium hydroxide.
In addition, the present invention also provides a kind of preparation method of bi-component acrylic cover lotion, including following step
It is rapid:
1) hydroxy-ethyl acrylate of 50% formula ratio, the A-174 of 50% formula ratio are weighed, is mixed standby as shell mix monomer
With；
2) n-dodecyl mercaptan, methyl methacrylate, acrylic acid, the Isooctyl acrylate monomer, third of formula ratio are weighed again
Olefin(e) acid butyl ester and remaining hydroxy-ethyl acrylate and remaining A-174 mix spare as core mix monomer；
3) anion emulsifier EPA-073, nonionic emulsifier LCN118 and Sol are tieed up into sodium-salt type anion emulsifier
CM30 adds water to be made into pre-emulsion；
4) it takes 1~1.5% step 3) that pre-emulsion is made, adds to equipped with blender, condenser pipe, variable-ratio peristaltic pump and 100
In the four-hole boiling flask for measuring journey thermometer, the 25~40% of initiator total amount are then weighed, are added in four-hole boiling flask, whole device
84~88 DEG C are heated to controllable temperature water-bath, reacts 30min；
5) initiator of remaining pre-emulsion and remainder is added dropwise into four-hole boiling flask, it is entire that process control is added dropwise in 3h
It is interior, and step 1) is added when 2h is added dropwise, shell mixed monomer solution is made, heat preservation 1h is added dropwise, is cooled to 65~70 later
DEG C, it adding step 2) and core mixed monomer solution is made, curing agent, reducing agent is then added, reaction 30min keeps the temperature 20min, it
Afterwards cooling down to 50 DEG C hereinafter, be added pH adjusting agent control pH value be 7.0~8.0, through 250 mesh filter-cloth filterings discharge, must produce
Object is the milky white lotion with blue light.
Compared with prior art, the beneficial effects of the present invention are:
1) in the present invention, due to using function monomer (hydroxy-ethyl acrylate, γ-methacryloxypropyl front three
Oxysilane) in hydroxyl and B component in isocyano (HPDI) reaction form covalent bond, and there is also big on inorganic ground
Hydroxyl is measured, equally also can react to form covalent bond with HPDI, and these covalent bonds are the more interfaces strong more than Van der Waals force
Active force, therefore greatly improve the adhesive force of paint film.
2) in the present invention, due to using special core-shell structure, carboxylic monomer is added in shell polymerization stage and polymerize, makes hydroxyl
It is distributed mainly on surface, is easier to contact simultaneously crosslinking curing with curing agent, improves crosslink density and curing agent service efficiency.
3) of the invention since the decentralized medium used is deionized water, organic solvent is free of, environment will not be caused bad
It influences.
4) emulsifier that the method for the present invention uses is free from the emulsifier of aryl oxide class, is free of APEO, monomer without formaldehyde or
Formaldehyde derivatives will not cause damages to human health.
5) though the present invention is two-component system, traditional two-component open system time is 2~3 hours, is tested through detection
It demonstrate,proves, the open hour prepared by this method are 3~5 hours.
6) in the present invention, due to making film that there is excellent temperature-change resistance, stain resistance and hydrophobic using organosilicon is introduced
Property.
