Problems solved by technology

[0004] But, the present inventor finds in research, and the existing addition mold glue that is used to make crystal diamond, its service life is short, because at high temperature, mold glue can react with product (as epoxy resin etc.), therefore It affects the service life of the mold glue, resulting in only about 20 mold turning times of the existing mold glue; in addition, the brightness of the crystal diamond prepared by using the existing addition mold glue is also relatively low

Abstract

The invention discloses addition-type mold rubber and a preparation method thereof. The addition-type mold rubber is prepared from the following raw materials in parts by weight: 70-85 parts of component A, 5-10 parts of component B, 0.2-2.0 parts of catalyst, 0.1-1.5 parts of inhibitor 1, 3-7 parts of white carbon black and 20-25 parts of inhibitor 2. The addition-type mold rubber disclosed by the invention has good tensile strength, tear strength and hardness, is very suitable for manufacturing of crystal drills and long in service life, the rolling-over number of times of the addition-type mold rubber reaches up to 35-45 times, and the brightness of the manufactured crystal drills is greatly improved.

Description

technical field [0001] The invention relates to the technical field of addition-type mold glue, in particular to the technical field of addition-type mold glue that can be used for making crystal diamonds. Background technique [0002] Addition mold glue has the characteristics of good transparency, easy deep curing, and small shrinkage rate. It is mainly used in the production of precision molds and exquisite replicas. [0003] 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 glue has better dimensional stability, linear shrinkage rate is less than 0.1%, heat resistance can reach above 250°C, and it will not restore when heated in a sealed environment. [0004] But, the present inventor finds in research, and the existing addition mold glue that is used to make crystal diamond, its service li...
