Abstract

The invention discloses a wood dipping processing multi-function modifier which comprises the following components by mass: 8%-12% of phenol, 10%-15% of formaldehyde, 6%-9% of phosphoric acid, 3%-8% of melamine, 6%-9% of urea, 3%-6% of zinc borate, 5%-10% of boric acid, 5%-10% of sodium octoborate, 3%-5% of dimethyl dithiocarbamate copper, 15%-50% of silica sol, and 0.5%-1% of fatty alcohol polyoxyethylene ether. The beneficial effect is that the wood dipping processing multi-function modifier has being flame retardant, anticorrosive, moth-proofing, enhancing, wear resistant, well erosion resistant and other advantages of, and can significantly improve the application value of processed wood.

Description

A kind of multifunctional modification agent for timber pickling process

Technical field

The present invention relates to wood treatment agent technical field, specifically a kind of multifunctional modification agent for timber pickling process.

Background technology

Timber be a kind of renewable, can recycling and can the green material of natural degradation and living resources, it has beautiful texture, color and luster is natural, texture is comfortable, plasticity is good, be easy to the advantages such as processing, is widely used in the fields such as interior decoration, Furniture manufacture, building construction, extraneous adornment.But timber also exists some defects, as the change due to moisture content produces drying shrinkage, bulking, thus cause the change of scantling and shape and the reduction of intensity, easily go mouldy rotten, easily by the erosion of entomogenous fungi moth, easy firing etc.Especially the artificial fast-growing woods timber that at present china natural resources is very abundant, except above-described timber inherent shortcoming, also there is the shortcomings (as poplar, China fir, cryptomeria etc.) such as material is soft, density is little, intensity is low, Surface Machining poor performance, its solid wood is utilized be very limited, only for the low value-added product such as wood-based plate, papermaking.In order to improve and overcome the shortcoming of artificial forest wood, improve its material grade, realize its increment efficiency utilization, functionality improvement must be carried out to artificial forest wood.

Summary of the invention

The object of the present invention is to provide a kind of fire retardant, anticorrosive, toughened and reinforced, stablize the good multifunctional modification agent for timber pickling process of resistance leachability.

The technical solution adopted for the present invention to solve the technical problems is: a kind of multifunctional modification agent for timber pickling process, and its component by mass percent proportioning is: phenol 8% ~ 12%, formaldehyde 10% ~ 15%, phosphoric acid 6% ~ 9%, melamine 3% ~ 8%, urea 6% ~ 9%, Firebrake ZB 3% ~ 6%, boric acid 5% ~ 10%, eight Boratex 5% ~ 10%, cupric dimethyldithio carbamate 3% ~ 5%, Ludox 15% ~ 50%, AEO 0.5% ~ 1%.

The mass concentration of described formaldehyde is 35wt% ~ 40wt%.

The mass concentration of described phosphoric acid is 20wt% ~ 25wt%.

Dioxide-containing silica in described Ludox accounts for 20wt% ~ 30wt%.

The preparation method of above-mentioned a kind of multifunctional modification agent for timber pickling process, comprises the following steps:

(1), each component is taken by weight ratio;

(2), add phenol and formaldehyde successively in a kettle., turn on agitator, slowly add sodium hydroxide solution adjust ph to 11 ~ 12, and be warming up to 55 DEG C ~ 65 DEG C gradually, then phosphoric acid and melamine is added, continue to be warming up to 80 DEG C ~ 85 DEG C, after insulation reaction 1.5 ~ 2h, be cooled to 70 DEG C ~ 75 DEG C, add urea again, insulation 15 ~ 25min, then Firebrake ZB and boric acid is added successively, react 15 ~ 20min at 65 DEG C ~ 75 DEG C after, adjust ph to 9 ~ 9.5, be cooled to less than 40 DEG C, then eight Boratexes are added, cupric dimethyldithio carbamate, Ludox and AEO, stir 10 ~ 15min, namely discharging obtains described a kind of multifunctional modification agent for timber pickling process.

The invention has the beneficial effects as follows, the present invention have concurrently fire-retardant, anticorrosion, mothproof, strengthen, the advantage such as wear-resisting, resistance leachability is good, significantly can promote the using value processing timber.
