Problems solved by technology

[0004] 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 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 an addition type mould gel for making a crystal drill and a preparation method of the addition type mould gel. The addition type mould gel comprises the following raw materials in parts by weight: 80-95 parts of a component A, 5-9 parts of a component B, 0.5-1.5 parts of a catalyst, 0.05-0.1 part of an inhibitor 1 and 10-25 parts of an inhibitor 2. The addition type mould gel disclosed by the invention is very suitable for making the crystal drill by means of tensile strength, tearing strength and hardness, and is long in service life, simple in preparation method, low in cost and very high in economic value; the mould turnover times reaches 35-40 times.

Description

technical field [0001] The invention relates to the technical field of mold glue, in particular to an addition-type mold glue, in particular to an addition-type mold glue that can be used for making crystal diamonds and a preparation method thereof. Background technique [0002] Mold glue is divided into addition mold glue and condensation mold glue. Condensation mold glue has excellent fluidity and mold release, easy to operate, stable mold size, heat resistance, chemical resistance, good physical properties and high tear strength, etc. Features, especially for unsaturated polyester products, good durability and long service life of the mold, but the condensation mold glue will produce low molecular substances in the production process, such as methanol, which will cause pollution and is not environmentally friendly; the addition mold It has the characteristics of good transparency, easy deep curing, and small shrinkage. It is mainly used in the production of precision mold...
