Description
Technical field
The invention belongs to seal gum technical field, particularly relate to a kind of fire resistant water resistant one-component polyurethane sealant and preparation method thereof, sealing glue can be widely used in the industrial circles such as automobile industry, Railway Transport Industry and new forms of energy industry.
Background technology
Containing isocyanate-terminated group in the material of main part of wet-solidifying single-component polyurethane seal gum, can at room temperature with the reaction of moisture in air, form high strength elastic body.Such seal gum has the performances such as good mechanical and physical performance, resistance to chemical attack, water-fast, low temperature resistant, anti-vibrating and impact performance, is therefore widely used in vehicle production assembling and maintenance, each field of mechanical workout.
But due to polyurethane chemistry structure, resistance toheat is poor after polyurethane sealant is cured as elastomerics, easily there is the phenomenons such as softening, molecular rupture, elastomer degradation under the high temperature conditions, cause its mechanical property to decline obviously.In the application of polyurethane elastomer, Long-term service temperature is no more than 90 DEG C, and the use temperature of short-term can not more than 120 DEG C.
In the research field of polyurethane sealant, there is a lot of research improving its thermotolerance aspect.
The method improving thermotolerance is mainly divided following several:
1, by modification mode, add resistant to elevated temperatures silicone resin wherein, as described in CN 1361221A, silicone resin content, up to 75 ~ 90%, makes its high-temperature behavior reach 180 ~ 220 DEG C, but the mechanical property making urethane itself good reduces.
2, by modification mode, in cross-linking process, add epoxide group, resistance toheat is promoted, but after sealing glue solidifying, hardness rises obviously, after reality use is bonding, the stressed easy formation stress concentration of bond, flexibility decrease.
3, by using polyester polyol synthesis of polyurethane prepolymer, the thermotolerance of polyester prepolyer is better than polyether prepolymer performance.Mainly because polyethers key under the high temperature conditions more easily ruptures, thermotolerance can be made to promote to some extent, but polyester key is more easily hydrolyzed under warm water condition, after bond rupture, mechanical properties decrease is obvious.Therefore adopt the obtained seal gum of polyester prepolyer to promote resistance toheat, but make water resistance obviously decline.
4, by adding the mode of latent curative, making polyurethane sealant crosslinked more abundant in the curing process, improving cross-linking density, thermotolerance is promoted.As described in Japanese Laid-Open Patent Publication 5283658, add kitimine, but easily have influence on the curing speed of One component Sealant.
5, from after still needing the synthesis by heat-resisting intermediate described in other class patents carry out interpolation and reach resistance toheat and promote different, process is complicated.Raw material described in this patent is common commodity, and seal gum preparation process is simplified.
6, the performance boost mentioned in other Patents, only keeps mechanical property constant 100 DEG C of thermal ageings after 1 week.
7, the tertiary amine catalyst adopted in this patent proves to have better resistance toheat compared to the organic tin catalyzer of the most common employing of one-component polyurethane sealant through test.
Although the resistance toheat of one-component polyurethane sealant can be made to promote to some extent by certain methods, water tolerance higher for temperature require higher, under the higher condition of mechanical property requirements, over-all properties still can not meet the demands.
