Abstract
The invention discloses a scrape coating environment-friendly modified polyurea waterproofing paint and a preparation method thereof. The waterproofing paint comprises the following raw materials in percentage by mass: 20% of polyether glycol, 10% of dinonyl phthalate, 20% of modified hexamethylene diisocyanate, 28% of polyether triols, 0.45% of titanium dioxide, 19.75% of isophoronediamine, 0.15% of dibutyltin dilaurate, 0.03% of organic silicon, 0.23% of ultraviolet light absorber, 0.02% of dispersing agent, 0.02% of color separation preventing assistant and 1.35% of water absorbent. The waterproofing paint disclosed by the invention contains 100% of solids, is tasteless, nontoxic and environment-friendly in construction, and is not affected by moisture and water in the environment; the formed film layer has excellent mechanical properties and weather resistance, favorable high and low temperature resistance, favorable solubility and corrosion resistance and good adhesive property with cement, steel, woods, glass fiber reinforced plastic products and other materials. In addition, the preparation method is simple, free of generating other pollutants, environment-friendly and sanitary.
Description
Technical field
The present invention relates to building coating field, specifically, relate to a kind of modification polyurea waterproof coating material.
Background technology
At building field, waterproof paint and cement, steel, timber, glass fiber reinforced plastics product etc. become one of important material of building field.As everyone knows, in architectural process, if do not accomplish good waterproof effect, the quality of its buildings is well imagined so, so it is particularly important that waterproof paint just seems.At present,, there is shortcomings in blade coating type waterproof paint:
(1) bad mechanical property;
(2) weathering resistance, high and low temperature resistance are unstable;
(3) solvent resistance and erosion resistance are low;
(4) in construction process, there are taste, poisonous, existence pollution;
(5) be subject to the impact of environment moisture and moisture larger.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defect, and blade coating type environment protection modification polyurea waterproof coating material that tasteless, nontoxic in a kind of construction, environmental protection and mechanical mechanics property are good and preparation method thereof is provided.
For addressing the above problem, the technical solution adopted in the present invention is:
Blade coating type environment protection modification polyurea waterproof coating material, is characterized in that, described waterproof paint comprises the raw material of following mass percent:
Polyether Glycols 20%, Dinonylphthalate 10%, modification hexamethylene diisocyanate 20%, polyether-tribasic alcohol 28%, titanium dioxide 0.45%, isophorone diamine 19.75%, dibutyl tin laurate 0.15%, organosilicon 0.03%, UV light absorber 0.23%, dispersion agent 0.02%, anti-color separation auxiliary agent 0.02%, water-retaining agent 1.35%.
The preparation method of blade coating type environment protection modification polyurea waterproof coating material, is characterized in that, its step is as follows:
A, first polyether Glycols, Dinonylphthalate are added in the four-hole reaction flask of 500ml, are warming up to 110 ℃ of vacuum hydro-extractions 4 hours;
B, be cooled to below 50 ℃ again, add the hexamethylene diisocyanate of modification, slowly heat up and be heated to 85 ℃, under vacuum condition, react 2.5 hours;
C, be cooled to 55 ℃ again, add organosilicon, stir 30 minutes, discharging sealing;
D, again polyether-tribasic alcohol is added in the four-hole reaction flask of 500ml, is warming up to 80 ℃, then add titanium dioxide, isophorone diamine, stir;
E, be warmed up to 110 ℃ again, vacuum hydro-extraction 4 hours;
F, be then cooled to 55 ℃, add dibutyl tin laurate, UV light absorber, dispersion agent and anti-color separation auxiliary agent, fully stir 10 minutes;
G, finally add water-retaining agent, stir discharging after stirring 20 minutes.
Owing to having adopted technique scheme, waterproof paint 100% solid content of the present invention, tasteless in construction, nontoxic, environmental protection, be not subject to the impact of environment moisture and moisture; After moulding, rete has excellent mechanical mechanics property and weathering resistance, good resistant of high or low temperature, good resistance to dissolubility and erosion resistance, has good adhesiveproperties with materials such as cement, steel, timber, glass fiber reinforced plastics products.In addition, preparation method is simple, produces environmentally-friendly sanitary without other pollutent.
For the further performance to coating of the present invention is tested, therefore its quality index is tested, its test knot result as shown in Table 1.
Table one quality index
| Performance index | I group | II group | III group |
| Tensile strength/MPa | 10.9 | 11.5 | 12.8 |
