Cantharias specimen and making method thereof

Abstract

The invention discloses a making method of an artificial cantharias specimen which is made by taking urea-formaldehyde resin as a main raw material and sodium hydroxide and glacial acetic acid as auxiliary raw materials. The making method comprises the following steps of: synthesizing a urea-formaldehyde resin raw monomer, pre-treating insects, preparing a ripe monomer, preparing a mould, fixing and embedding an insect sample, demoulding and polishing, wherein the raw monomer is formed by adding sodium hydroxide and glacial acetic acid into formaldehyde and urea as raw materials and then polymerizing, and the proportion of the formaldehyde to the urea is equal to 55:18 to 50:22; the urea-formaldehyde resin has the shrinking percentage of 5-20%, the hardening time of 2-5d and the bubbling number of 0-5; and the ripe monomer is prepared by mixing the liquid urea-formaldehyde glue of the raw monomer and an extension agent, adding glacial acetic acid and stirring, wherein the extension agent is selected from polyethylene glycol 600, DEHP (Di 2-Ethyl Hexyl Phthalate) and DINP (Diisononyl Phthalate). The making method disclosed by the invention is simple and rapid in process, low in cost and the raw materials are easy to purchase; and a sample is high in strength and good in toughness, glossiness and transparency.

Description

technical field

[0001] The invention relates to a handicraft production technology, in particular to an insect specimen and a production method thereof. Background technique

[0002] Insect amber specimens not only have permanent preservation of insect materials, but also can be further made into wearing ornaments, small ornamental handicrafts, tourist products, and have both scientific research value and market value. The relationship between the production process level of insect amber specimens. The preservation effect, ornamental value and production cost of specimens. Chinese patent CN3134935.8 records a kind of artificial amber and its manufacturing process. Its invention is based on mixing a variety of unsaturated resins as the main raw material, adding curing agent and other auxiliary materials; the molding method of artificial amber is to quickly turn over the mold Molding; unsaturated resin is an unsaturated resin formed by condensation of ethylene glycol and pro...
