Problems solved by technology

[0002] At present, the preservation of biological specimens is mainly soaked in formaldehyde (formalin), or plasticized by silica gel for biological specimens. Formaldehyde is toxic and odorous. Harmful to the human body and pollute the environment
Using silica gel to make biological plasticized specimens, the production process is cumbersome, and the reagents used contain volatile organic solvents and chloroplatinic acid, which will damage the health of the operator during the specific operation
At the same time, they also have problems such as short storage time, easy deformation, and high production cost.

Abstract

The invention discloses an environment-friendly biological plasticizer for biological specimen preservation, which is prepared from the following components in parts by weight: 100 parts of silicone resin, 20-100 parts of plasticizer, 0.5-5 parts of catalyst and 2-10 parts of crosslinking and curing agent, wherein the silicone resin is hydroxyl-terminated methyl silicone oil, the plasticizer is methyl-terminated methyl silicone oil, the catalyst is organotin, and the crosslinking and curing agent is organosiloxane. The invention has the advantages of no toxicity, no harm, no smell and no pollution, and is transparent; the specimen plasticized by the plasticizer has the advantages of strong authenticity, good hand feeling and high vividness, and can be stored for a long time; the environment-friendly biological plasticizer for biological specimen preservation can ensure the manufacture of biological specimens to be carried out at ordinary temperature, and avoids using chloro-platinic acid and other noble and highly-corrosive reagents, thereby greatly lowering the cost and reducing the harm to operating personnel; and the invention avoids using a diluter, and simplifies the operation steps.

Description

Technical field: [0001] The invention relates to an environment-friendly biological plasticizer used for preserving biological specimens, and belongs to the technical field of plasticizers. Background technique: [0002] At present, the preservation of biological specimens is mainly soaked in formaldehyde (formalin), or the biological specimens are plasticized with silica gel. Formaldehyde is poisonous and odorous, which is harmful to the human body and pollutes the environment. Using silica gel to make biological plasticized specimens is cumbersome, and the reagents used contain volatile organic solvents and chloroplatinic acid, which will damage the health of the operator during the specific operation. At the same time, they also have problems such as short storage time, easy deformation, and high production cost. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a non-toxic, har...
