The present invention is further arranged to: the titanium dioxide is Detitanium-ore-type.
The present invention is further arranged to: the titanium dioxide and zinc oxide are nanoscale.
Another goal of the invention of the present invention is to provide a kind of preparation method of environmental protection coating material, include the following steps:
Step 1: according to parts by weight, it is fine to weigh 30-40 parts of acrylic acid ester emulsion, 0.1-0.2 parts of organic silicon modified by polyether, ethoxy
Tie up 0.4-0.5 parts of element, 0.3-1 parts of polyacrylate alkali swelling type lotion, 5-10 parts of titanium dioxide, 5-10 parts of zinc oxide, oxygen
Change copper 10-20 parts, 10-20 parts of bismuth oxide, 1-2 parts of pH adjusting agent, 0.5-0.8 parts of dispersing agent, 2-3 parts of antifreezing agent, water 20-30
Part；
Step 2: first successively dispersing agent, organic silicon modified by polyether being added to the water, stirred evenly, titanium dioxide, two is then added
Zinc oxide, copper oxide, bismuth oxide, stir evenly；
Step 3: acrylic acid ester emulsion is added, is stirring evenly and then adding into pH adjusting agent for pH and is adjusted to 9；
Step 4: sequentially adding hydroxyethyl cellulose, polyacrylate alkali swelling type lotion, antifreezing agent, stir evenly.
In conclusion the invention has the following advantages:
1, acrylic acid ester emulsion uses the low VOC acrylic acid ester emulsion of Core-shell technology polymerization, does not need to add in film forming procedure
The coalescing agent and auxiliary coalescing agent of VOC scope, can reduce the VOC release of coating, reach excellent environmental-protecting performance；
2, organic silicon modified by polyether is with non-toxic and tasteless, inverse dissolubility is strong, from milkiness, good, chemical stability, thermal stability are high, disappears
The advantages that speed is fast, the foam inhibition time is long is steeped, can reduce VOC；
3, hydroxyethyl cellulose can make coating have good workability and appearance, avoid increasing VOC, but can reduce painting
The water resistance of film.The influence that type lotion can make up for it hydroxyethyl cellulose to water-resistant coating and polyacrylate alkali soluble rises；
4, on the one hand titanium dioxide and zinc oxide are used as pigment, assign film covering power and color, another aspect nanoscale two
Titanium oxide and nanoscale zinc oxide have good anti-microbial property, and the antibacterial action time is long, can reduce VOC generation.It compares
In rutile titanium dioxide, anatase titanium dioxide activity with higher；5, copper oxide and bismuth oxide are with higher
Thermal coefficient, while there is Heat-stable performance, it can assign coating excellent heating conduction, increase the heat dissipation performance of wall；
6, pH adjusting agent can prevent coating from forming a film too early in storage, transport, use process as polymerization inhibitor.Using second two
Amine is capable of the pH value of adjusting coating as pH adjusting agent；And copper oxide can react with ethylenediamine and water and generate diethylene triamine conjunction
Copper ion, while having hydroxide ion generation.Bismuth oxide also can generate complex compound with ethylenediamine and water.Therefore, copper oxide and
Bismuth oxide can play the role of fixed ethylenediamine, to reduce the volatilization of ethylenediamine, reduce VOC release；
7, lauryl sodium sulfate and OP-10 can promote the particle of aggregation to be uniformly dispersed, and prevent the sedimentation and cohesion of particle,
Form stable suspended substance；
8, ethylene glycol and propylene glycol are able to ascend the anti-freezing property of coating, but will increase the VOC release of coating again.And ethoxy
The addition of cellulose, lauryl sodium sulfate and OP-10 can reduce the release of ethylene glycol and propylene glycol.
