Abstract
Related single-composition polyurethane waterproof paint is prepared by mixing materials of the following formula, in parts by weight, 600-680 parts of polyether DL2000, 3050 120-200 parts of polyether, 230-250 parts of chlorinated paraffin, 70-90 parts of dioctyl phthalate, 50-70 parts of iron black, 700-1200 parts of calcite powder, 150-160 parts of kaolin, 100-140 parts of toluene diisocyanate (TDI), 30-50 parts of stannous octoate, 8-12 parts of a curing agent, and 300-350 parts of xylene. Compared with conventional polyurethane waterproof paint, the single-composition polyurethane waterproof paint is simple for film coating, good in coating effect, free of surface bubbles, and good in tensile strength and elongation at break, and dried polyurethane is smooth and flat in surface and excellent in bonding effect.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of single-component polyurethane water-proof paint
Background technology
In recent years, national development makes rapid progress, and urban construction is like a raging fire, along with the carrying out of various engineering construction, the infiltration seepy question of roofing, ground, vault annoyings people all the time, and waterproofing work is arisen at the historic moment thus, various water-proof material emerges in an endless stream, and waterproofing industry is flourish.Waterproof paint enters everybody visual field as a kind of waterproof material, and it becomes the trend of waterproof gradually with the novel theory of hi-tech, low cost, super environmental protection, thus is widely used by various engineering.Polyurethane water-proof paint is a kind of Environmental-protecwaterproof waterproof paint of liquid state construction, is with imported polyurethane performed polymer for fundamental component, without the additive such as tar and pitch.It is the moisture contact after fixing in air, forms firm tough and tensile without the anti-film of seam entirety of one deck in substrate surface.But everybody finds after use monocomponent polyurethane, single-component polyurethane water-proof paint of today still has the following disadvantages: use single-component polyurethane water-proof paint easy to foaming in construction process in the market, surface effect is plain, is also difficult to reach good waterproof effect; The phenomenon of sticky hand can be there is in dry rear surface.
Summary of the invention
For the defect of above polyurethane water-proof paint, the object of this invention is to provide a kind of single-component polyurethane water-proof paint, improve the over-all properties of polyurethane coating.
Technical scheme of the present invention is: a kind of single-component polyurethane water-proof paint, and its formula is by weight percentage:
The single-component polyurethane water-proof paint of said components, its preparation method comprises the following steps:
(1) polyethers DL2000, polyethers 3050, clorafin, dibutyl ester, the stirring of mixing post-heating is added in reactor;
(2) add iron oxide black, calcite in powder, kaolin, be heated to 115 DEG C, keep temperature 115-120 DEG C, be incubated 2 hours, vacuumize in insulating process, vacuum tightness is-0.09Mpa;
(3) then add tolylene diisocyanate (TDI) to react, 2 hours reaction times, temperature 85 DEG C;
(4) stannous octoate is added after having reacted, its continuation reaction of catalysis, 1 hour reaction times, temperature 85 DEG C;
(5) add 208 solidifying agent after having reacted, special-purpose catalyst dimethylbenzene, mixes, and temperature is reduced to 60 DEG C of dischargings.
Fine particle calcium carbonate is added in above-mentioned feed composition.
The reaction of the performed polymer building-up process of polyurethane water-proof paint of the present invention mainly tolylene diisocyanate and polyether glycol, when the mol ratio of isocyanato and hydroxyl is at appropriate ratio, the performance of urethane is somewhat dependent upon the molecular structure of selected polyether glycol.
The use of catalyzer, under the condition of same linking agent, the add-on of the sub-tin of octoate catalyst has a desired value, and reaction can be made to carry out more complete, and the Main Mechanical of polyurethane water-proof paint is also better.
Adding of appropriate filler, reaction precipitation demixing phenomenon can be alleviated, extend period of storage.Filler has the characteristics such as swelling property, tackiness, dispersiveness, and add a certain amount of filler, the structure that molecular chain also can be made to be formed is more perfect.
By adjusting the proportional quantity of polyether glycol, tolylene diisocyanate and polyether glycol react, when the mol ratio of isocyanato and hydroxyl is at appropriate ratio, the performance of urethane is selecting the polyether glycol gained polyurethane material good springiness of two functionality, elongation at break high, select the polyether-tribasic alcohol of three-functionality-degree simultaneously, the polyurethane material tensile strength of gained, hardness are higher, and elasticity, elongation at break are lower, this be polyether-tribasic alcohol easily and tolylene diisocyanate formed caused by 3 D cross-linked structure.Adopt polyether glycol mixing match in the performed polymer of polyurethane waterproof material, its over-all properties is better, and tensile strength is, elongation at break, shore hardness have good performance.
