Abstract
The invention discloses a loss-resistant flame retardant anticorrosive wood production method including the steps of pretreatment of wood, preparation of a treatment liquid and vacuum pressure immersing treatment. The treatment liquid is prepared by evenly mixing 20-30% of guanylurea phosphate, 15-20% of water-soluble ammonium polyphosphate, 8%-15% of boric acid, 2%-5% of ammonium molybdate, 5%-10% of sodium octoborate, and 20%-50% of silicon sol, add adding water to dissolve into solution in 10 wt %-20 wt % concentration. The beneficial effect is that by microwave processing, immersing property of the wood immersing treatment is greatly increased, the related wood treating agent has significant improving effects on the aspects of wood fire retardant smoke suppression properties, stability of resistance to erosion, corrosion protection security and the like, and the loss-resistant flame retardant anticorrosive wood production method is simple in process, low in cost, strong in practicability, and convenient to popularize and apply.
Description
Technical field
The present invention relates to Wooden modifying processing technology field, specifically a kind of production method preparing flame-retardant smoke inhibition anti-current mistake preserving timber.
Background technology
Along with the raising of China's expanding economy and living standards of the people, society increases day by day to the demand of timber.Timber is the biomaterial of natural reproducible, and its development and utilization meets the requirement of environmental protection, but it exists easy firing, easily to go mouldy the shortcoming such as rotten.In recent years, along with the frequent generation of fire incident, cause great damage to the lives and properties of people and living environment, thus the environmental-protection fireproof consciousness of people constantly strengthens, and furniture is fire-retardant and fire prevention demand in house is increasing.The fire retardant that the current fire retardant generally adopted at fire retarding wood protection technical elements has phosphate flame retardants, borate fire retardant, ammonium polyphosphate flame retardant or fixes with amino resins.Fire retardant treatment process is generally surperficial coating processing and impregnation process two kinds of modes and non-pressure process and vacuum-pressure processes two kinds of methods.Non-pressure process is immersed in by timber in the lower fire resistant fluid of viscosity at ambient pressure.Pressurization is placed in pressure pan by timber, is first evacuated, and then pressurizes fire-retardant liquid press-in wood internal.Current wood fire retardant product variety is various, and the fire retardant treatment process of its flame-retardant formulations composition and fire retardant and timber is also being constantly updated and improved.
Summary of the invention
The object of the present invention is to provide the production method preparing flame-retardant smoke inhibition anti-current mistake preserving timber that a kind of technique is simple, cost is low and practical.
The technical solution adopted for the present invention to solve the technical problems is: a kind of production method preparing flame-retardant smoke inhibition anti-current mistake preserving timber, comprises the following steps:
(1), timber pretreatment: removed the peel by log, cut after saw cuts open into the specification of required size, dry 8 ~ 24h under the condition of 50 DEG C ~ 80 DEG C, controls the moisture content of timber not higher than 25%, then microwave treatment 10 ~ 30min;
(2), Treatment Solution is prepared: take guanylurea phosphate 20% ~ 30% by weight ratio, water-soluble poly ammonium phosphate 15% ~ 20%, boric acid 8% ~ 15%, ammonium molybdate 2% ~ 5%, eight Boratex 5% ~ 10%, Ludox 20% ~ 50% mix, obtain a kind of composite wood inorganic agent, and it is dissolved in water, be mixed with mass concentration 10wt% ~ 20wt% Treatment Solution;
(3) Treatment Solution, the timber that step (1) obtains being placed in step (2) obtained carries out vacuum impregnation process, vacuum 0.08 ~ 0.1MPa, retention time 30 ~ 60min, then 0.3 ~ 0.6MPa is forced into, retention time 30 ~ 90min, then timber is taken out, drier under the condition of 50 DEG C ~ 80 DEG C, obtain described flame-retardant smoke inhibition anti-current and lose preserving timber.
Step (1) described log comprises one or more in China fir, pine, poplar, birch, cork wood.
Dioxide-containing silica in step (2) described Ludox accounts for 25wt% ~ 30wt%.
The invention has the beneficial effects as follows, the present invention adopts microwave treatment to substantially increase the dipped type of timber pickling process, and the aspects such as inorganic agent involved in the present invention is qualitative to the flame-proof smoke-suppressing of timber, anti-current unstability, anticorrosion security all have clear improvement, preparation technology of the present invention is simple simultaneously, cost is low, practical, easy to utilize.
