Problems solved by technology

[0003] Commonly used water-borne preservatives such as CCA, ACC, ACA, etc. contain heavy metal ions such as chromium, etc., which are also harmful to humans, animals and the environment; in recent years, inorganic boron used in wood preservatives has the advantages of low toxicity and wide antibacterial range. The Chinese invention patent of CN1915616B and the Chinese invention patent with the application publication number of CN102941606A all disclose wood preservatives using borate as raw material, but inorganic borons are water-soluble, and their anti-loss performance is poor. In the environment, it is easy to lose, which limits its further application

Embodiment 1

[0032] Embodiment 1: a kind of multi-purpose antiseptic, comprises antibacterial agent: 1 part of boric acid; Anti-loss agent: 3 parts of phenolic resin; Surfactant: polyoxyethylene lauryl ether phosphate and sodium dodecylbenzenesulfonate 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 the condition of normal temperature and normal pressure, first put the mixture of polyoxyethylene lauryl ether phosphate and sodium dodecylbenzenesulfonate, furfuryl alcohol and water into the container and stir, raise the temperature to 40°C, and then add Phenolic resin and boric acid are stirred for 30 minutes to form a liquid preservative.

Embodiment 2

[0034] Embodiment 2: a kind of multi-purpose antiseptic, comprises antimicrobial agent: 2.5 parts of boric acid; Anti-loss agent: 9 parts of urea-formaldehyde resins; Surfactant: tristyryl polyoxyethylene ether phosphate and dodecylbenzenesulfonate 2.2 parts of calcium acid calcium mixture; organic solvent: 8 parts of polyvinyl alcohol; water: 4.5 parts.

[0035] The preparation method is as follows: under normal temperature and normal pressure conditions, first put the mixture of tristyryl polyoxyethylene ether phosphate and calcium dodecylbenzenesulfonate, polyvinyl alcohol and water into the container and stir, and heat up to 50 ℃, add urea-formaldehyde resin and boric acid in turn, and stir for 120 minutes to make a liquid preservative.

Embodiment 3

[0036] Embodiment 3: a kind of multi-purpose antiseptic, comprises antibacterial agent: sodium borate 2 parts; Anti-loss agent: polyvinyl acetate 4.5 parts; Surfactant: laureth polyoxyethylene ether phosphate and dodecylbenzene sulfonate 3.5 parts of sodium acid mixture; organic solvent: 4.5 parts of furfuryl alcohol; water: 4 parts.

[0037] The preparation method is as follows: under the condition of normal temperature and normal pressure, first put the mixture of polyoxyethylene lauryl ether phosphate and sodium dodecylbenzenesulfonate, furfuryl alcohol and water into the container and stir, raise the temperature to 65°C, and then add Polyvinyl acetate and sodium borate were stirred for 45 minutes to form a liquid preservative.

Abstract

The invention relates to a multifunctional preservative and belongs to the technical field of mold prevention and corrosion prevention. The multifunctional preservative comprises components in parts by weight as follows: 1-6 parts of an antibacterial agent, 3-10 parts of a leaching resistance agent, 0.1-4 parts of a surfactant, 3.5-10 parts of an organic solvent and 2-6 parts of water. The preservative can be used for mold prevention and corrosion prevention of wood, leather, hemp, bamboo, vines and other materials, has little toxicity and is good in leaching resistance.

Description

technical field [0001] The invention relates to the technical field of anti-mildew and anti-corrosion, in particular to a multi-purpose preservative. Background technique [0002] Wood preservative is a preparation that can inhibit wood mold and decay, and can also be widely used in the anti-mold and anti-corrosion of leather, hemp, bamboo, rattan and other materials; commonly used wood preservatives are divided into oil preservatives, oil-borne preservatives and There are three types of water-borne preservatives. Among them, oil-based preservatives and oil-borne preservatives are rarely used or banned due to their great toxicity to humans and animals and the harm to the environment. Water-borne preservatives have been widely used in recent years. [0003] Commonly used water-borne preservatives such as CCA, ACC, ACA, etc. contain heavy metal ions such as chromium, etc., which are also harmful to humans, animals and the environment; in recent years, inorganic boron used in w...
