Abstract

The invention discloses a wood processing aid and a preparation method thereof. The wood processing aid comprises the following components by mass: 20-25% of nano calcium carbonate, 5%-10% of nano silicon dioxide, 8%-12% of amidinourea phosphate, 4%-8% of zinc borate, 1%-4% of ammonium molybdate, 6%-10% of sodium octoborate, 0.5%-1% of polyoxyethylene fatty acid ester and 30%-55% of water. The wood processing aid has the advantages of excellent flame retardance, smoke suppression, corrosion resistance and dimensional stability and the like, the surface hardness, wear resistance, impact toughness and water resistance and other advantages of the treated wood are significantly improved, and the wood use effect and application field are improved.

Description

A kind of timber processing aid and preparation method thereof

Technical field

The present invention relates to wood treatment agent technical field, specifically a kind of timber processing aid and preparation method thereof.

Background technology

Timber and goods thereof are widely used in interior decoration, Furniture manufacture, building construction and extraneous adornment, but it exists expand with wet and contract with dry, poor dimensional stability, the problem that perishable, fire protecting performance is poor, will have impact on result of use and the application of its goods.How to promote the problem that effect has become wood working industry extensive concern.

Summary of the invention

The object of the present invention is to provide that a kind of modified effect is good, cost is low and it is fire-retardant, anticorrosion to have concurrently and increase powerful timber processing aid and preparation method thereof.

The technical solution adopted for the present invention to solve the technical problems is: a kind of timber processing aid, and its component by mass percent proportioning is: nano-calcium carbonate 20% ~ 25%, nano silicon 5% ~ 10%, guanylurea phosphate 8% ~ 12%, Firebrake ZB 4% ~ 8%, ammonium molybdate 1% ~ 4%, eight Boratex 6% ~ 10%, polyoxyethylene carboxylate 0.5% ~ 1%, water 30% ~ 55%.

Described nano-calcium carbonate is the precipitated calcium carbonate nano particle of particle diameter at 1 ~ 100nm.

Described nano silicon is the aerosil nano particle of particle diameter at 20 ~ 40nm.

The preparation method of above-mentioned a kind of Wood modifier, comprises the following steps:

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

(2) in agitator, add water and nano-calcium carbonate and nano silicon, add polyoxyethylene carboxylate again, at 40 DEG C ~ 75 DEG C temperature, high-speed stirred 20 ~ 50min, then ultrasonic disperse 15 ~ 30min, other component is added after being cooled to normal temperature again, make to be mixed together 5 ~ 10min, obtain a kind of timber processing aid of the present invention.

The invention has the beneficial effects as follows, the present invention has excellent fire-retardant, the function that presses down cigarette, anticorrosion and dimensional stability, and can also significantly promote the advantages such as its case hardness, wearability, impact flexibility, water proofing property to process timber, improve result of use and the application of timber.
