Embodiment 1

[0022] Liquid epoxy resin: Dow's 331 resin is used as component A, and methyl hexahydrophthalic anhydride is mixed with an appropriate amount of ultraviolet absorber and antioxidant to form a curing agent as component B, which overcomes the epoxy resin The original weather resistance is extremely poor, easy to yellow and other shortcomings, when used according to the weight ratio A: B = 1: 1 mixed evenly to become a special glue;

[0023] Use high-quality glass rhinestone or zircon imitation diamond as the model, bond it to the surface of glass or metal plate, and then cover it with high-quality silica gel or plastic to cure to make the product mold;

[0024] Use the above-mentioned special glue for epoxy resin as a raw material, inject it into the cavity of a silica gel or plastic mold with an automatic glue dispenser or manually, and then send it into an oven to heat and solidify to form a semi-finished product;

[0025] Take out the resin imitation drill from the silicone ...

Embodiment 2

[0028] Liquid epoxy resin: Dow's 331J resin is used as component A, and methyl hexahydrophthalic anhydride is mixed with an appropriate amount of ultraviolet absorber and antioxidant to form a curing agent as component B, which overcomes the epoxy resin The original weather resistance is extremely poor, easy to yellow and other shortcomings, when used according to the weight ratio A: B = 1: 1 mixed evenly to become a special glue;

[0029] Use high-quality glass rhinestone or zircon imitation diamond as the model, bond it to the surface of glass or metal plate, and then cover it with high-quality silica gel or plastic to cure to make the product mold;

Embodiment 3

[0034] Liquid epoxy resin: Hongchang's 128 resin is used as component A, and methyl hexahydrophthalic anhydride is mixed with an appropriate amount of ultraviolet absorber and antioxidant to form a curing agent as component B, which overcomes the original epoxy resin. Some have extremely poor weather resistance, easy yellowing and other shortcomings. When using them, they can be mixed evenly in the ratio of weight ratio A:B=1:1 to become special glue;

[0035] Use high-quality glass rhinestone or zircon imitation diamond as the model, bond it to the surface of glass or metal plate, and then cover it with high-quality silica gel or plastic to cure to make the product mold;

[0036] Use the above-mentioned special glue for epoxy resin as a raw material, inject it into the cavity of a silica gel or plastic mold with an automatic glue dispenser or manually, and then send it into an oven to heat and solidify to form a semi-finished product;

Abstract

The invention relates to a production technology of an anti-yellowing resin imitation diamond with high light transmittance and high weatherability, and belongs to the field of resin processing technology. The production technology includes the steps of using a high-quality rhinestone or zircon imitation diamond as a mold base, sticking the mold base on the surface of a piece of glass or a metal plate, and then covering a high-quality silica gel or plastic cement to obtain a product mould after solidification; making a special-purpose resin glue raw material by evenly mixing the special-purpose epoxy resin glues, A and B, at a ratio of 1:1; injecting the glue into the cavity of the resin mould artificially or via an automatic glue-dripping machine for solidification; obtaining a finished product after moulding. The color performance can be realized by the methods of spraying base color, plating base color and adding color concentrates into glue. The resin prepared by the technology of the invention is good in weatherability and is not easy to become yellow. Besides, the resin has a light transmittance which is over 90%, a thermal deformation temperature which is over 80 DEG, and a Shore hardness which is over 80.

Description

technical field [0001] The invention relates to a production process of a resin imitation drill, in particular to a production process of a resin imitation drill with high light transmittance, high weather resistance and anti-yellowing performance, and belongs to the technical field of resin processing. Background technique [0002] Diamond is one of the earliest gem materials used by human beings. It is the hardest material on the earth. Because of its beauty, rarity, durability, harmlessness and brilliance, it has become the most popular gemstone. The pursuit of diamonds is tireless, and it has become the dream of every woman to own it. However, due to the scarcity of diamonds and the high price, not everyone can own them. Therefore, making a diamond imitation product has become the direction of continuous efforts of some businesses. [0003] Based on people's tireless admiration and pursuit of diamonds, the demand for imitation diamonds in the global jewelry market is ext...
