Problems solved by technology

[0002] The existing addition-type platinum vulcanizing agents are generally two-component, which need to be added separately before being used, and then mixed together. The processing technology is complicated, and after being added to the raw material, the storage time of the raw material is short, which can easily lead to death. glue, resulting in scrap

Abstract

The invention relates to the technical field of platinum vulcanizing agents and preparation methods thereof, in particular to a single-component addition-type platinum vulcanizing agent and a preparation method thereof. The single-component addition-type platinum vulcanizing agent is prepared from, by weight, 2000-3000 parts of methyl rubber with the molecular weight of 700000-800000, 600-800 parts of low-hydrogen-containing silicone oil, 600-800 parts of high-hydrogen-containing silicone oil, 50-100 parts of platinum complex, 100-150 parts of alkynol compound and 50-90 parts of azoic compound. The preparation method includes the following steps that 1, the methyl rubber with the molecular weight of 700000-800000 is put into a kneader and kneaded for 5 min at a room temperature; 2, the low-hydrogen-containing silicone oil, the high-hydrogen-containing silicone oil, the alkynol compound and the azoic compound are slowly added in batches, then the platinum complex is added after complete even mixing is achieved, and the mixture is kneaded for 1 h; 3, discharged products are separately packaged for use, two inhibitors are selected and blended, a suitable hydrogen content of the hydrogen-containing silicone oil is selected, a suitable content and suitable activity of the platinum complex are selected, the two components are combined and directly added in the mixing process, and the preservation time of mixed raw materials is more than 3 times that of original raw materials.

Description

technical field [0001] The invention relates to the technical field of a platinum vulcanizing agent and a preparation method thereof, in particular to a single-component addition type platinum vulcanizing agent and a preparation method thereof. Background technique [0002] The existing addition-type platinum vulcanizing agents are generally two-component, which need to be added separately before being used, and then mixed together. The processing technology is complicated, and after being added to the raw material, the storage time of the raw material is short, which can easily lead to death. Glue, resulting in scrap. For this reason, there is an urgent need to develop a one-component addition type platinum vulcanizing agent and a preparation method thereof to solve the deficiencies in the prior art. Contents of the invention [0003] One of the purposes of the present invention is to provide a one-component addition type platinum vulcanizing agent. The two components ar...
