Problems solved by technology

[0003] However, the inventors have found in research that the existing addition mold glue used to make crystal diamonds has a short service life, because at high temperatures, the mold glue will react with products (such as epoxy resin, etc.), so It affects the service life of the mold glue, resulting in only about 20 times of overturning of the existing mold glue

Abstract

The invention discloses addition type mold rubber suitable for manufacturing a crystal drill and a preparation method of the addition type mold rubber. The addition type mold rubber is prepared from the following raw materials in parts by weight: 85-90 parts of a component A, 10-15 parts of a component B, 0.5-1.0 part of a catalyst, 0.06-0.08 part of an inhibitor 1 and 25-30 parts of an inhibitor 2. The addition type mold rubber disclosed by the invention has excellent tensile strength, tear strength and hardness, the number of mold rolling-over times is as high as 35-50, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of crystal drills, in particular to the technology of mold glue used in the manufacture of crystal drills, in particular to an addition-type mold glue specially suitable for manufacturing crystal drills and a preparation method thereof. Background technique [0002] At present, the commonly used mold glue for crystal diamonds is addition-type mold silicone, because the addition-type mold silicone has the advantages of high transparency and good mold release. Compared with plastic, addition mold plastic has better dimensional stability, linear shrinkage rate is less than 0.1%, heat resistance can reach above 250 ℃, and it will not restore when heated in a sealed environment. [0003] However, the inventors have found in research that the existing addition mold glue used to make crystal diamonds has a short service life, because at high temperatures, the mold glue will react with products (such as epoxy resin,...
