Abstract
The invention relates to a copper dimethyldithiocarbamate wood preservative. The copper dimethyldithiocarbamate wood preservative is a solvent prepared from effective components and water. The effective components comprise, by weight, 16%-30% of bivalent copper ions, 0-32% of dimethyl carbamodithioic acid, 40%-60% of acetone and 4%-15% of surface active agent, and the bivalent copper ions and dimethyl carbamodithioic acid react to obtain copper dimethyldithiocarbamate. The copper dimethyldithiocarbamate wood preservative is formed by the bivalent copper ions and dimethyl carbamodithioic acid (SDDC), acetone is adopted as a solvent, and the preservative for forming preservative-treated wood at a time is formed. The preservative has the good corrosion preventing and termite preventing performance, has no toxic effect on people or environment, and is good in loss resisting performance. Due to the fact that the surface active agent is added, the corrosion preventing capacity of a preparation can be effectively improved, and the stability and penetrating performance of the preparation are guaranteed.
Description
Technical field
The present invention relates to timber preservative, in particular cupric dimethyldithio carbamate timber preservative.
Background technology
The preserving timber of China has started to popularize, but up to the present, waterborne-type preservation the most conventional is still CCA(main chemical compositions copper chromium arsenic), ACQ(is at individual balcony composition alkyl cuprammonium compound), CA (copper azoles) etc., account for that anticorrisive agent uses total amount more than 90%.But these anticorrisive agents all exist certain deficiency, such as CCA contains the toxic element such as chromium, arsenic, there is harm to environment.Meanwhile, the anticorrosive wood of these kinds becomes color comparatively deeply because of the existence of copper ion, loses timber nature true qualities.Therefore, people are constantly seeking environmental protection, colourless timber preservative, such as the water soluble salts such as boride.But this kind of water soluble salt anticorrisive agent leach resistance extreme difference, limits the use of such anticorrosive wood environment out of doors.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, providing a kind of has well anticorrosion, termite-proof performance, does not have toxic action to human and environment, and the cupric dimethyldithio carbamate timber preservative that leach resistance is good.
For achieving the above object, technical solution of the present invention is: cupric dimethyldithio carbamate timber preservative, by active principle and water configure solvent; Described active principle consists of: bivalent cupric ion 16 ~ 30wt%, SDD 0 ~ 32wt%, acetone 40 ~ 60wt%, surfactant 4 ~ 15wt%, is describedly obtained by reacting cupric dimethyldithio carbamate with bivalent cupric ion and SDD.
Preferably, described bivalent cupric ion is one or more in copper chloride, copper sulphate, copper nitrate, monoethanolamine copper, cupric dimethyldithio carbamate.
Preferably, the cupric dimethyldithio carbamate that generates of reaction and surfactant sum account for the 10-25wt% of solvent.
Preferably, the weight ratio of described bivalent cupric ion and activating agent is 1:0.5 ~ 1:0.9375.
Preferably, described surfactant be in AEO 0-20 type, AEO 0-25 type, neopelex, dodecyl sodium sulfate, dodecanamide propyl amine oxide, cocamidopropyl propyl amide amine oxide one or more.
Preferably, described surfactant is didecyl Dimethy ammonium chloride, dodecylbenzyl alkyl dimethyl ammonium chloride, two eight alkyl dimethyl ammonium chloride, two dodecyl dimethyl ammonium chloride, eight alkyl ten alkyl dimethyl ammonium chloride, cocotrimonium chloride, didecyl Dimethy ammonium bromide, dodecyl benzyl dimethyl ammonium bromide, two eight alkyl dimethyl ammonium bromides, didodecyldimethylammbromide bromide, eight alkyl ten alkyl dimethyl ammonium bromides, cocotrimonium ammonium bromide.
By adopting above-mentioned technical scheme, the invention has the beneficial effects as follows:
The present invention forms cupric dimethyldithio carbamate (CDDC) by cupric and SDD (SDDC), and adopt acetone as solvent, form the anticorrisive agent that disposable process class becomes preserving timber, improve preservative treatment production efficiency, reduce the productive manpower and equipment cost.For improving preparation anticorrosion ability, ensureing stability and the permeance property of preparation simultaneously, in cupric dimethyldithio carbamate timber preservative timber preservative, adding non-ionic surface active agent or quaternary cationics.Comparatively CCA is good in the effect of anti-white rot and soft corruption for the wooden unit of CDDC process, also comparatively CCA and ACA is all strong for resistance leachability, environment-protecting asepsis, anticorrosive wood color is the light brown of natural beauty, and the set time short (after process, namely 1h fixes), its intensity index can not be reduced after the timber high temperature drying of CDDC process, when contacting with medium carbon steel, not find corrosion.
