Description

Functional type environmental protection treatment agent of a kind of timber pickling and preparation method thereof

Technical field

The present invention relates to wood treatment agent technical field, functional type environmental protection treatment agent of specifically a kind of timber pickling and preparation method thereof.

Background technology

Timber be a kind of renewable, can recycling and can the green material of natural degradation and Biological 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 also there are some defects in timber, as: easily expand with wet and contract with dry, easily go mouldy rotten, easily by entomogenous fungi moth erosion, easy firing etc., this will greatly limit its effect and Application Areas.Carrying out necessary dipping modification to timber, is improve one of wood performance, the important channel promoting timber effect and practical value.

Summary of the invention

The object of the present invention is to provide that a kind of resistance leachability is strong, the feature of environmental protection good, the functional type environmental protection treatment agent of fire-retardant, rot-resistant timber pickling and preparation method thereof.

The technical solution adopted for the present invention to solve the technical problems is: a kind of functional type environmental protection treatment agent of timber pickling, and its component by mass percent proportioning is: phenol 8% ~ 15%, formaldehyde 8% ~ 10%, phosphoric acid 6% ~ 8%, melamine 3% ~ 5%, urea 8% ~ 10%, zinc borate 6% ~ 10%, boric acid 3% ~ 5%, eight Sodium Tetraborate 5% ~ 10%, silicon sol 27% ~ 50%.

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

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

Dioxide-containing silica in described silicon sol accounts for 25wt% ~ 30wt%, and pH is 6 ~ 8.

The preparation method of the functional type environmental protection treatment agent of above-mentioned a kind of timber pickling, 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 65 DEG C ~ 75 DEG C, add urea again, insulation 15 ~ 25min, then zinc borate is added, reaction 10 ~ 15min, add boric acid again, reaction 10 ~ 15min, add sodium hydroxide solution adjust ph to 9 ~ 9.5, be cooled to 35 DEG C ~ 40 DEG C, then eight Sodium Tetraboratees and silicon sol is added, stir 20 ~ 50min, namely discharging obtains the functional type environmental protection treatment agent of described a kind of timber pickling.

The invention has the beneficial effects as follows, the present invention is with functions such as fire-retardant, anticorrosion, enhancings, qualitative to the fire retardant, anticorrosive of process timber, anti-current unstability, strengthen the aspects such as wear resistance and be all significantly improved.
