Description
Technical field
Liquid and the preparation method of the infiltration liquid, more particularly to one kind are penetrated into the present invention relates to a kind of impregnated timber
Micro-capsule impregnating fluid with and preparation method thereof.
Background technology
Timber is big with the ratio of strength to weight as a kind of biomaterial being made up of natural polymer, power consumption of polymer processing
It is few, the advantages of environmental pollution is relatively small, but there is also that material is loose, Variations of Wood Properties is big simultaneously, easily it is subject to environment and micro- life
The infringement of thing and destroyed deficiency.
Traditional timber preservative treatment can effectively improve wood durability to a certain extent, and prolonging wood makes
With the life-span, but most traditional timber preservative is with elements such as copper, chromium, arsenic as principle active component, and these metal ingredients
Have to health of human body and Environmental security it is potentially hazardous so that preservative treatment material especially artificial forest preservative-treated timber
Using being subject to certain restrictions.
Being presently used for the preservative of wood preservation mainly has including copper azoles (CuAz), ammoniacal copper quaternary (ACQ), alkylammonium compound
(AAC) chromium copper arsenate (CCA), is added in interior waterborne preservative.But the concern of people, anti-corrosion are increasingly subject to environmental problem
The environmental problem of agent also turns into the key of preservative selection.Because some preservatives have difference during production and use
The leakage of degree and ooze out, while waste and old preservative-treated timber is reclaimed can be adversely affected to environment, and endanger the strong of the mankind
Health.Many preservatives announce that limitation is used by many countries.Environmental Protection Agency USA announces to contain arsenic since 2003
The CCA of compound cannot be used for civil buildings.
Therefore, find to turn into person poultry harmless, new food preservative environmentally safe, only poisonous to microorganism and currently grind
The emphasis studied carefully.Research finds that some timber, plant have certain anti-corrosion, insect prevention performance in itself, and this is because itself contains
Some tanninses, terpenoid substance have toxic action to microorganism, can be used to process timber as natural antiseptic agent.Although
Many researchs all show that plants essential oil and plant extract have a good rotproofness, but its its set under conditions of water-soluble
Property, stability all receive very big influence.In order that natural antiseptic agent is preferably bonded in timber, and make its active component
With slow release effect, it is necessary to find out a kind of technique for improving natural antiseptic agent stability.
