Example Embodiment
[0032] Example 1: A multi-purpose preservative, including antibacterial agent: 1 part of boric acid; anti-blow agent: 3 parts of phenolic resin; surfactant: a combination of laureth polyoxyethylene ether phosphate and sodium dodecyl benzene sulfonate 0.1 part of the mixture; organic solvent: 3.5 parts of furfuryl alcohol; water: 2 parts.
[0033] The preparation method is as follows: under normal temperature and normal pressure, first put the mixture of laureth polyoxyethylene ether phosphate and sodium dodecyl benzene sulfonate, furfuryl alcohol and water into a container, stir, heat to 40°C, and add sequentially Phenolic resin and boric acid are stirred for 30 minutes to form a liquid preservative.
Example Embodiment
[0034] Example 2: A multi-purpose preservative, including antibacterial agent: 2.5 parts of boric acid; anti-running agent: 9 parts of urea-formaldehyde resin; surfactant: tristyryl polyoxyethylene ether phosphate and dodecyl benzene sulfonate 2.2 parts of a mixture of calcium acid; organic solvent: 8 parts of polyvinyl alcohol; water: 4.5 parts.
[0035] The preparation method is as follows: under normal temperature and normal pressure, first put the mixture of tristyryl polyoxyethylene ether phosphate and calcium dodecylbenzene sulfonate, polyvinyl alcohol and water into the container and stir, and heat to 50 ℃, add urea-formaldehyde resin and boric acid one by one, and stir for 120 minutes to make liquid preservative.
Example Embodiment
[0036] Example 3: A multi-purpose antiseptic, including antibacterial agent: 2 parts of sodium borate; anti-draining agent: 4.5 parts of polyvinyl acetate; surfactant: laureth polyoxyethylene ether phosphate and dodecyl benzene sulfonate 3.5 parts of sodium mixture; organic solvent: 4.5 parts of furfuryl alcohol; water: 4 parts.
