Abstract
The invention discloses an adhesive capable of being cured at normal temperature and particularly relates to a zirconium strength adhesive capable of being cured at normal temperature with waterproof and corrosion proof performances and a preparation method thereof. The adhesive is prepared by warming, stirring and reacting raw materials such as toluene diisocynate, polytetrafluorofuran polyether glycol, 3, 3'-dichloro-4, 4'-diaminodiphenylmethane, polypropylidene ether dihydric alcohol, diethyltoluenediamine and a diluent. The adhesive is not only long in service life, but also low in using cost. The adhesive is suitable for protecting metal parts such as hydraulic mechanical parts which are soaked in water for a long time.
Description
Technical field
The present invention relates to a kind of sizing agent and preparation method thereof.Specifically, be that having of can solidifying is at normal temperatures water-fast, the zirconium intensity sizing agent of antiseptic property and preparation method thereof.Be applicable to the protection of the metal parts of water conservancy machinery parts and so on long period of soaking in water.
Background technology
In water conservancy machinery manufacturing, all know, for extending the work-ing life of water conservancy machinery parts, common method is to be applied to protective rubber in ship components and the painting of water conservancy machinery parts outside, traditional protective rubber, water resistance and corrosion resistance nature are poor, and easily hydrolysis is soaked and will be come off for 2 ~ 3 months in water, work-ing life is short, therefore, within 2 ~ 3 months, just the metal parts being immersed in water need be taken out, re-start gluing, not only cumbersome, and use cost is higher.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of sizing agent that can be curing at normal temperatures.This sizing agent, long service life, use cost is low.
Another problem that the present invention will solve is to provide a kind of method of preparing sizing agent that can be curing at normal temperatures.
The problem to be solved in the present invention is realized by technical scheme once:
Sizing agent feature that can be curing at normal temperatures of the present invention is the raw material that comprises following parts by weight:
80 ~ 90 parts of tolylene diisocyanates;
30 ~ 40 parts of polytetrafluoro furans polyether Glycols;
8 ~ 12 parts of chloro-4, the 4 ＇-diaminodiphenylmethane of 3,3 ＇-bis-;
11 ~ 13 parts of polytrimethylene ether dibasic alcohol;
2 ~ 3 parts of diethyl toluene diamines;
8 ~ 10 parts of thinners.
The feature of the method for the described sizing agent that can be curing at normal temperatures of preparation is to comprise the following steps successively:
First polytetrafluoro furans polyether Glycols, polytrimethylene ether dibasic alcohol are dropped into and have in the container vacuumizing with dehydrating function, be heated to 115 ~ 118 degrees Celsius, vacuumize dehydration 1 ~ 2 hour;
Then, be cooled to below 40 degrees Celsius, and add tolylene diisocyanate, continue to be warming up to 70 ~ 75 degrees Celsius, and at this temperature, react 1.5 ~ 1.8 hours;
Afterwards, add thinner, mix, obtain material A;
Afterwards, chloro-4, the 4 ＇-diaminodiphenylmethane of 3,3 ＇-bis-and diethyl toluene diamine are added in another container, and be heated to 79 ~ 81 degrees Celsius, mix, obtain material B;
Finally, material A and material B are put together and are mixed, and carry out vacuum defoamation, obtain can be curing at normal temperatures sizing agent.
Take such scheme, have the following advantages:
The sizing agent warp of taking such scheme to make is on probation, and water resistance and corrosion resistance nature are strong, and facile hydrolysis can not soak about 2 years in water, without coming off and being hydrolyzed trendy this generation, long service life.Compare with background technology, can avoid often the metal parts being immersed in water being taken out, re-starting the trouble of gluing, thereby greatly reduce use cost.
