Description
Technical field
The present invention relates to a kind of ancient tree treehole to repair silicon rubber, more particularly, to not only with ageing-resistant and good biological phase
Capacitive, surface hydrophobicity rain-proof, by repairing, ancient tree wound healing can be promoted, improve tree looks, prolong with mould proof, anti-corrosion, insect prevention
Long ancient tree life-span, the ancient tree treehole for strengthening ancient tree growth repair silicon rubber.
Technical background
Ancient tree is the rarity in forest tree resource, existing big tree, especially ancient and well-known trees, for various reasons, ancient tree
Bast or xylem are easily formed various treehole, if carried out not in time at anti-corrosion by wound on the trunk of ancient tree
Reason, when wound site endanger by bacterium class caused by rain erosion, in the course of time, formation treehole.The treehole reparation of ancient tree is
One technical measures of old trees' conservancy, by treehole reparation, promote ancient tree wound healing, improve tree looks, the ancient tree longevity can be extended
Life, strengthen ancient tree growth.Treehole, which repairs silicon rubber, at present is filled using brick and tile, stone, concrete or wooden unit, table
Layer grout off, the drawbacks of its is maximum inorganic material fill in organic tree body, both sides' contact surface combination is not tight, usually occurs
Gap or cracking, rainwater intrusion is caused to aggravate internal rotten level.Another aspect cement category alkaline matter, the reply life to tree body
Length plays inhibition.Also useful polyurethane foam reparation, but polyurethane weatherability is poor, and biocompatibility is bad, still not enough manages
Think.
Mc Dougall in 1954 are reported to the extremely sensitive homoiothermous various cell tissues of ectocine and liquid
During the organosilicon product into contact of state, semi liquid state and rubber like state, the developmental condition of its cell tissue finds no anomaly
Result, show organic silicon rubber will not cell growth exert an adverse impact, with good biocompatibility.

Uniformly after mixing, mixture is filled in treehole as early as possible before curing with the mode of needle cylinder injection and blade coating, treats that silicon rubber is inhaled
Environment steam is received, after 48 hours all solidify, removes the unnecessary silicon rubber on treehole periphery.
Bio-compatible ancient tree treehole of the present invention repairs silicon rubber and can both solve anti-corrosion in treehole repair process, kill
Bacterium, desinsection while to the reparation of ancient tree treehole and it can fill up, recovering the normal growth after treehole reparation has good protection effect,
Infiltration tack is good, and safety and environmental protection, surface rain water is easy to slide, and residual is seldom, effectively prevents rainwater from invading tree body.
Bio-compatible ancient tree treehole of the present invention repairs silicon rubber has affinity and good biological compatible with tree body
Property, pH value is neutrality, and material is elastomer, is advantageous to arboreal growth and is not easily susceptible to cracking, and material surface shows as hydrophobicity,
Effectively prevent rainwater from invading tree body, can be with mould proof, anti-corrosion, insect prevention, effect is good, ageing-resistant.
Tree body can effectively be killed and suppressed to the copper 8-quinolinolate that the bio-compatible ancient tree treehole is repaired in silicon rubber
Fungi, moth and termite etc..
The bio-compatible ancient tree treehole is elastomer after repairing 48 hours solidify afterwards of silicon rubber, be advantageous to arboreal growth and
It is not easily susceptible to cracking.Surface exhibits are hydrophobicity after solidification, effectively prevent rainwater from invading tree body.
The white oil（Technical grade）, proportion is less than 1 flash-point 130（℃）40 DEG C of kinematic viscosity 4-5（cSt）Pour point-
5（℃）Properties of product：Highly refined product, it is colourless, tasteless, it is nontoxic.Main application：For chemical fibre, close fine, textile machine rubber
Glue plasticising etc..The white carbon is reinforcing, can improve adhesion strength, matter height is inexpensive.The organotin makees catalyst, can be with
