Abstract

The invention discloses an environment-friendly preservative. The environment-friendly preservative comprises the following components in parts by weight: 35-50 parts of triazole nucleoside carboxylicacid modified hyperbranched polylysine, 2-5 parts of choline borate, 0.5-1.5 parts of lecithin, 4-7 parts of graphene, 0.5-1.5 parts of sodium glycyrrhetate, 6-10 parts of an antiseptic Chinese herbal medicine extract, 1-2 parts of a celery extract, 1-2 parts of a Hamamelis virginiana extract, 10-20 parts of ethanol and 150-200 parts of deionized water. The invention also provides a preparation method of the environment-friendly preservative. The environment-friendly preservative disclosed by the invention has obvious preservative effect, diverse performance, wide range of wood rot bacteria and insects resistance, stable performance in the process of storage and transportation, and safe and environment-friendly use.

Description

technical field [0001] The invention relates to the technical field of preservatives, in particular to an environmentally friendly preservative and a preparation method thereof. Background technique [0002] Cosmetics, washing products, paper, paint, wood, feed, etc. commonly used in daily life contain sugar, starch, pigment, deionized water and other raw materials that are susceptible to microbial contamination, which brings certain difficulties to the storage of these products , affecting the quality and use of the product. Especially wood, when the temperature, moisture, humidity, and pH are suitable, it is easy to be corroded by insects and bacteria, which will shorten the service life of wood and cause huge economic losses. Therefore, it is particularly important to carry out anti-corrosion treatment on wood, which is an important way and means to prolong the service life of wood, improve the level of wood utilization, and save wood resources. [0003] Preservative is...
