Description
Technical field
The present invention relates to platinum vulcanizing agent and preparation method thereof technical field, particularly relate to single component add-on type platinum vulcanizing agent and preparation method thereof.
Background technology
Existing add-on type platinum vulcanizing agent generally is two-pack, is need add respectively separately in use, more mixing to together, and complete processing is complicated, and joins after inside raw material, and the shelf-time of raw material is short, very easily causes dead glue, thus generation is scrapped.For this reason, research and development single component add-on type platinum vulcanizing agent and preparation method thereof is needed badly, to solve the deficiencies in the prior art.
Summary of the invention
Two-pack, for providing single component add-on type platinum vulcanizing agent, unites two into one, directly adds time mixing by an object of the present invention, and mixing after the raw material shelf-time can reach original more than 3 times.
Another object of the present invention is for providing the preparation method of above-mentioned single component add-on type platinum vulcanizing agent.
For achieving the above object, the present invention adopts following technical scheme:
Single component add-on type platinum vulcanizing agent, comprises each component of following weight part:
More preferably, the hydrogen richness of described silicon oil of low hydrogen content is between 0.36-0.75%.
More preferably, the hydrogen richness of described high containing hydrogen silicone oil is between 1.5-1.6%.
More preferably, described alkynol compound is acetylene hexalin.
More preferably, described azo-compound is Diisopropyl azodicarboxylate or 2,2'-Azobis(2,4-dimethylvaleronitrile).
The preparation method of the single component add-on type platinum vulcanizing agent described in above-mentioned any one, comprises the following steps:
1) 70 ~ 800,000 molecular weight methyl rubbers are dropped into kneader, room temperature mediates 5 minutes;
2) in batches by silicon oil of low hydrogen content, high containing hydrogen silicone oil, alkynol compound, azo compound slowly adds, and adds platinum complex low temperature again mediate 1 hour to completely to mix;
3) discharging separately use can be packed.
Beneficial effect of the present invention is: select two kinds of inhibitor mixtures; Suitable hydrogen content selected by containing hydrogen silicone oil, and platinum complex selects suitable content and active, two-pack is united two into one, directly add time mixing, and mixing after the raw material shelf-time can reach original more than 3 times, preparation method is simple, greatly can reduce production cost.
