Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art through specific situations.
Example 1
The invention provides special glue for producing medical instruments, which comprises the following components in parts by weight: 40 parts of modified polyolefin aqueous resin liquid, 10 parts of polyester aqueous resin emulsion, 30 parts of anion tourmaline, 25 parts of formaldehyde, 4 parts of oxidant, 5 parts of chain-regulating agent and 10 parts of deionized water.
Specifically, the anion tourmaline is 400-mesh anion tourmaline powder.
Specifically, the oxidizing agent is a sodium bicarbonate solution with the concentration of 15%.
Example 2
the invention provides special glue for producing medical instruments, which comprises the following components in parts by weight: 45 parts of modified polyolefin aqueous resin liquid, 15 parts of polyester aqueous resin emulsion, 40 parts of anion tourmaline, 27 parts of formaldehyde, 6 parts of oxidant, 5 parts of chain-regulating agent, 0.5 part of aqueous wetting and leveling agent, 0.5 part of aqueous defoaming agent, 0.5 part of pH regulator and 20 parts of deionized water.
Example 3
The invention provides special glue for producing medical instruments, which comprises the following components in parts by weight: 50 parts of modified polyolefin aqueous resin liquid, 20 parts of polyester aqueous resin emulsion, 50 parts of anion tourmaline, 30 parts of formaldehyde, 7 parts of oxidant, 7 parts of chain-regulating agent, 1 part of aqueous wetting and leveling agent, 1 part of aqueous defoaming agent, 1 part of pH regulator and 30 parts of deionized water.
The invention provides a special glue for producing medical instruments, which comprises the following steps:
Step one, uniformly mixing the weighed modified polyolefin water-based resin liquid and the polyester water-based resin emulsion, and standing for 15 minutes;

And step five, adding the anion tourmaline, and fully stirring for 30 minutes to prepare the glue containing the anion powder.
Specifically, the condensation reaction in the second step is to keep the temperature until the solution becomes half milk white after the formaldehyde is dripped, namely the condensation end point.
according to researches, the hydrogen bond is the source of the influence of the glue on the stability, so that the acting force of the hydrogen bond needs to be reduced to solve the stability problem, namely the number of hydroxyl groups is reduced, the number of-OH is reduced under the condition of adopting a certain temperature, meanwhile, a six-membered ring is formed to the maximum extent, the steric hindrance is increased, and meanwhile, a chain-regulating agent is added to reduce the branched chain degree.
in addition, formaldehyde is harmful to human body and must be disposed of, so that an oxidant is required to be added to oxidize formaldehyde into carbon dioxide and water.
