Abstract

The invention discloses a neutral whitening agent containing a drug carrier and a preparation method thereof, and belongs to the technical field of tree protection. The neutral whitening agent containing the drug carrier includes the following components by the weight percentage: 0.5 to 2% of the drug carrier, 0.1 to 0.6% of a dispersant, 0.1 to 0.5% of a wetting agent, 0.3 to 1% of a film formingauxiliary agent, 15 to 30% of a filler, 0.5 to 1% of cellulose, 8 to 25% of an emulsion, 0.1 to 0.8% of a whitening agent, and water added to make the total amount of 100%. The prepared neutral whitening agent containing the drug carrier has the advantages of strong bonding strength, long protection time and good frost damage prevention effect.

Description

technical field [0001] The invention relates to the technical field of tree protection, in particular to a neutral whitening agent containing a drug carrier and a preparation method thereof. Background technique [0002] Drying of trees has the following advantages: sterilization, prevention of germ infection, and accelerated wound healing; insecticide, insect repellent, killing overwintering eggs and dry insects in the bark. Because pests generally like black, dirty places, they don't like white, clean places. After the trunk is painted white, the pests in the soil will not dare to climb up the tree along the trunk to harm the tree, and it can also prevent the bark from being bitten by animals such as rodents; prevent frostbite and sunburn, avoid frost damage in early spring, and the temperature at night is very low in winter During the day, when the sun shines, the temperature rises, and the trunk is dark brown, which is easy to absorb heat, and the temperature of the tru...
