4, Ma Ling such as flies at people's " DP mould inhibitor ", and main component is 2, and 5-two chloro-3-bromophenols have good anti-mold effect, but act on single, the cost height, poorly water-soluble, protective treatment inconvenience, the protection phase falls short of.
5, " 79-7 " Vermins-proof mildew-proof agent of people such as Liu Yun, main component is a glycol dibromide, and certain Vermins-proof mildew-proof effect is arranged, but the protection phase is short, cost is high, and water-insoluble, protective treatment inconvenience.
6, " Compound B " bamboo wood mould inhibitor of Wu Danren.Its main component is boride, fluoride and quaternary amine, and its protection effect is good, and is water-soluble, and it is convenient to handle, but stationarity is poor.
7, the NETT wood preservative of the WP-1 of Qinghai wood preservative factory and wood preserving plant, Ministry of Railways Beijing is used for bamboo wood protection, the former weak effect, and coloration is arranged, and latter's protection effect is better, but price is higher.
Above-mentioned several bamboo wood protective agents and wood preservative are carried out research of branch folding and control experiment, " Compound B " and " NETT " performance the best, but have stationarity difference and the higher shortcoming of price.
The history in existing more than 70 year of the research and development of wood preservation, and the research of bamboo wood preservative have only 20 surplus year, the copper that exploitation is the most successful, chromium, arsenic series wood preservative (CCA series) because the toxicity height is harmful to environment, have been limited to use in the recent period in history.For many years, people are devoted to the research and development of CCA substitute products always.The various characteristics of having developed except that stationarity all can be suitable with CCA, even surpass the multiple preservative of CCA.Fail to have breakthrough aspect the promptly anti-molten pouring of stationarity always, obtain gratifying progress only.
Summary of the invention
The object of the present invention is to provide a kind of efficient, wide spectrum, low cost, good stationarity is arranged, the term of validity is long, can satisfy the bamboo and wood protecting agent of different environments for use requirements.
The research that the present invention lasts 6 years is altogether gathered in the torrid zone, bamboo producing region, subtropics and have been identified 8 kinds of bamboo bole moths, adheres to 5 sections separately, gathers, separates, cultivates, and has identified 52 kinds of Mold and Rot Fungi, adheres to 4 inferior bamboo 6 guiding principles 16 orders, 18 sections 31 separately and belongs to.Determined 3 kinds of the main moth of bamboo wood 2 sections, main mould rotten fungi 9 belongs to 14 kinds.Many kinds of chemical agents are being carried out on the basis of Preliminary screening, designing 16 kinds of protective agent prescriptions.The main large-scale sympodial bamboo that produces with Yunnan is the examination material, with main moth and main mould rotten fungi is object, indoor cultivation through reaching 6 years, the experimental study of the repeated multiple times of constant temperature and humidity inoculated and cultured and outdoor open-air cultivation has been succeeded in developing the serial protective agent of " ZBB+X " of the present invention (name certainly) finally.Simultaneously also carried out the research of protection processing method, having grasped to have good water-solubility by the series protective agent in treatment fluid, was water-insoluble key technology and in handling material well secured property is arranged.
" ZBB+X " serial protective agent adds different X component according to the different environment for use objectives of defense with safety requirements based on zinc salt, boric acid, borate.The X composition has one or both in the medicaments such as fluoride, quaternary ammonium salt, tpn, penta sodium pentachlorophenate, Phoxim emulsion, and the weight ratio of " ZBB+X " each composition is: zinc salt: boric acid: borate: one or both in fluoride, quaternary ammonium salt, tpn, penta sodium pentachlorophenate, the Phoxim emulsion=1.8～2.2: 0.8～1.2: 2.4～3.6: 2～3.
The present invention compared with prior art has following characteristics:
1, high-efficiency broad spectrum: insect protected, mildew-resistant and three anti-effects such as anticorrosion are arranged, promptly have broad spectrum activity.It is mothproof, anti-mold effect and domestic best bamboo wood protective agent " Compound B " are suitable with wood preservation fire retardant " NETT ", but antiseptic effect is better than the two, the protection phase of indoor material is estimated more than 20 years, to protection phase of outdoor use material be 4-6.This protective agent was once used in International Horticultural Expo Garden bamboo tower building materials are handled, and was respond well, do not occur any problem so far.
