Abstract

The invention discloses an environment-friendly high-viscosity tree whitening agent and belongs to the technical field of preparation of agricultural materials. A macromolecular chain modifier with massive alkyl groups is utilized herein, so that macromolecule components can enter the macromolecular chain modifier easily; kaolin lamellas are dispersed evenly in a rubber phase to form physical crosslinking points, so that adhesion stability is improved, and separation rarely occurs. Barnacle cement and mussel adhesive proteins added herein help improve structural stability of the whitening agent herein in terms of biological macromolecules; a system with self-assembly and crosslinking network is formed, so that good adsorption and film-forming stability are guaranteed, and adhesion stability during use is improved; biomass adhesive components prepared by means of fermenting and the like help improve adhesion to trunks; the materials used are green, so that the environment is never contaminated. The problem is solved that existing common traditional tree whitening agents have poor adhesion, drop easily and may cause soil contamination.

Description

technical field [0001] The invention belongs to the technical field of agricultural material preparation, and in particular relates to an environment-friendly high-viscosity tree whitening agent. Background technique [0002] Trunk whitewashing refers to the process of whitewashing the trunk base with a mixture of quicklime, water, salt, adhesive and lime sulfur. Its purpose is to prevent germ infection, play a role in sterilization, insecticide, insect control and so on. Whitening of tree trunks is an important link that cannot be ignored in the construction of urban landscaping. Common trunk whitening method is calcium sulfur quicklime whitening agent and novel trunk whitening agent. [0003] In urban landscaping, evergreen tree species can add color and vitality to the monotonous autumn and winter seasons. However, unlike southern regions, few evergreen tree species can survive after being transplanted to the north. The main reasons are as follows: The first is freezin...
