Abstract

The invention discloses biocompatible ancient tree hole restoration silicon rubber, which is prepared from an ingredient A and an ingredient B, wherein the ingredient A is prepared from 65 to 85 weight percent of hydroxyl-terminated polydimethylsiloxane, 10 to 30 weight percent of white carbon black and 5 to 10 weight percent of polydimethylsiloxane; the ingredient B is prepared from 20 to 40 weight percent of partial hydrolystates of tetramethoxysilane , 5 to 15 weight percent of methyltriacetoxysilane partial hydrolystates, 30 to 40 weight percent of white oil, 1 to 3 weight percent of organic tin, 5 to 15 weight percent of 8-oxine copper and 5 to 15 weight percent of white black carbon. In the use process, the ingredient B is added into the ingredient A to be stirred and mixed accordingto the weight parts of ratio of (8 to 10):(1 to 2). A silicon rubber protection layer is formed in the restoration position; the protection layer can effectively kill and inhibit tree body fungi, moths, white ants and the like; the rain water is prevented from invading into the tree body; the ancient tree wound heeling is promoted; the tree appearance is improved; the life of the ancient tree isprolonged; the growth of the ancient tree is enhanced.

Description

technical field [0001] The invention relates to a silicone rubber for repairing tree holes in ancient trees, in particular, it not only has anti-aging and good biocompatibility, but also has a hydrophobic and rain-proof surface, and can also be mildew-proof, anti-corrosion, and insect-proof. Improve the appearance of trees, prolong the life of old trees, and strengthen the growth of old trees to repair the old tree holes with silicone rubber. technical background [0002] Ancient trees are treasures in forest resources. Existing large trees, especially ancient and famous trees, due to various reasons, the phloem or xylem of ancient trees are injured, and various tree holes are easy to form on the trunks of ancient trees. Carry out anti-corrosion treatment in time. When the wounded part is harmed by bacteria caused by rainwater erosion, tree holes will be formed over time. The tree hole restoration of ancient trees is a technical measure for the protection of ancient trees. ...
