Abstract
The invention discloses a method for preparing single-component polyurethane waterproof paint by using hydrocarbon oil. The method comprises processes of mixing and production of raw materials. The hydrocarbon oil improved single-component polyurethane waterproof paint prepared by the method has the characteristic of realizing resource utilization of the hydrocarbon oil. Compared with the prior single-component polyurethane waterproof paint, the single-component polyurethane waterproof paint saves large amount of petrochemical resource and reduces the material cost. In addition, the tensile strength and breaking elongation performance of the paint are remarkably improved, so the method remarkably improves the waterproof effect of the paint.
Description
Affiliated technical field
The present invention relates to the production technology category of mono-composition poyurethane water-proof paint, specifically, relate to a kind of method of utilizing hydrocarbon ils to prepare mono-composition poyurethane water-proof paint.
Background technology
At present, domestic mono-composition poyurethane water-proof paint is that raw material makes base polyurethane prepolymer for use as by polyreaction with polyether glycol, tolylene diisocyanate (TDI) mainly, adds color stuffing, softening agent, defoamer, Preparation of Catalyst then and forms.But,, more color stuffing is not dewatered with polyethers owing to do not take vacuum hydro-extraction at the polyreaction polyethers prior at present, so the trace water that polyethers and color stuffing are brought into makes mono-composition poyurethane water-proof paint easy skinning in storage, poor stability easily bubbles during construction, influences quality product.In addition, because the influence of international petroleum market in recent years, main raw material(s) price rises such as picture polyether glycol, tolylene diisocyanate are very fast, especially tolylene diisocyanate price ascensional range nearly 100%, and the selling price amount of increase of mono-composition poyurethane water-proof paint is very little, only percentum causes this product not have profit substantially, has also had a strong impact on using and developing of this product.So, utilize inexpensive refinery byproduct hydrocarbon ils to substitute the low-cost mono-composition poyurethane water-proof paint of part polyether glycol and softening agent preparation, not only can improve product performance, reduce product cost, also can save the petrochemical industry resource of a large amount of preciousnesses, realize the recycling of refuse, so this product has good marketing prospect.
Summary of the invention
Purpose of the present invention is exactly to realize the recycling of refuse, utilizes inexpensive refinery byproduct hydrocarbon ils to substitute part polyether glycol and softening agent, prepares a kind of stable performance, with low cost, the simple mono-composition poyurethane water-proof paint of synthesis technique.
Realize that the method that the present invention utilizes hydrocarbon ils to prepare mono-composition poyurethane water-proof paint is:
At first selected the present invention utilizes hydrocarbon ils to prepare the raw material of mono-composition poyurethane water-proof paint and prepares by following prescription (weight %):
Polyethers 2000 17-22;
Polyethers 330N 10-15;
Hydrocarbon ils 8-12;
Wilkinite 0.4-0.6;

Dibutyl tin laurate 0.1-0.3.
After proportioning raw materials is selected, carry out production technique:
At first polyethers 2000, polyethers 330N and hydrocarbon ils being joined in the reactor, start stirring, and be warming up to 40-55 ℃ of adding wilkinite and talcum powder, compound in the reactor is continued to be warming up to 120 ℃, is to vacuumize under the 0.06MPa condition 2 hours in vacuum tightness.Be cooled to 60 ℃ then and add Benzoyl chloride and tolylene diisocyanate, be warming up to 85 ℃ again and stir and reacted 3 hours.Be cooled to 50 ℃ then and add carbon black slurry and dibutyl tin laurate again, stirred 20-40 minute, measure its viscosity 5,000-12 gets final product discharging during 000 centipoise.
The present invention utilizes the mono-composition poyurethane water-proof paint of hydrocarbon ils preparation to compare following advantage with existing mono-composition poyurethane water-proof paint:
1, technology is reasonable: with the vacuum hydro-extraction 2 hours under 120 ℃ of conditions together of powder and polyethers, the negative impact that the trace water of having avoided polyethers and color stuffing to bring into causes has improved the stability in storage and the application property of coating before polyreaction.
2, no free toluene diisocyanate to environment and body harmless, belongs to the environment-friendly type waterproof paint;
3, hydrocarbon ils is the refinery byproduct, low price, and wide material sources can reduce cost 22% than existing mono-composition poyurethane water-proof paint;
4, hydrocarbon ils can replace 10% polyether glycol and 100% dibutyl phthalate softening agent, has both improved material property, has also saved the petrochemical industry resource of a large amount of preciousnesses, has realized the recycling of refuse.
The present invention utilizes the performance of the mono-composition poyurethane water-proof paint of hydrocarbon ils preparation and existing mono-composition poyurethane water-proof paint as shown in table 1:
Table 1
| Performance | Waterproof paint of the present invention | Existing waterproof paint |
| Tensile strength | ??3.58MPa | ??1.9MPa |
| Elongation at break | ??837％ | ??550％ |
| Low temperature flexibility | -40 flawlesses | -30 flawlesses |
| Cost unit/kilogram | ??8.6 | ??11.2 |
By the table in as seen, the hydrocarbon ils that utilizes of the present invention prepares mono-composition poyurethane water-proof paint, its tensile strength and elongation at break all improve a lot, thereby have obviously improved waterproof effect, and have reduced the coating cost.
