Abstract
The invention discloses a wood adhesive agent and a preparation method thereof. The wood adhesive agent comprises the following components by mass: 8%-20% of organic montmorillonite, 5%-10% of dibutyl phthalate, 10%-15% of polyvinyl alcohol (PVA), 2%-5% of polyisocyanate, 5%-10% of glycerol, 4%-8% of copper borazine, 1%-3% of dodecyl sodium sulfate, and 30%-65% of distilled water, the organic montmorillonite is Na-based montmorillonite with the particle size in 25 nm to 75 nm, and the surface of the Na-based montmorillonite is activated by octadecyl dimethyl hydroxyethyl methyl ammonium chloride. The beneficial result is that the wood adhesive agent has the advantages of good performance, good waterproof performance, strong adhesive force and no toxic and environmental protection, and the like, and has good heat resistance, low cost, and simple preparation process.
Description
Technical field
The present invention relates to wood processing technique field, specifically a kind of Wood adhesive and preparation method thereof.
Background technology
At present, China's Wood adhesive is mainly based on traditional phenolic aldehyde, urea aldehyde, terpolycyantoamino-formaldehyde resin, high to petrochemical material degree of dependence, and the product price large problem that fluctuates still is given prominence to.Urea-formaldehyde resin viscose binder low price, but the poisonous residual volume such as free formaldehyde is high, and not water-fast, product specification is lower; Resol viscose binder has the advantages such as poisonous remnants are low, bonding strength is high, water-fast, and product specification is higher, but raw material phenol price is higher, therefore is difficult in China's large-scale application; There is the materials such as residual formaldehyde and be harmful to environment and human body in melamine-formaldehyde resin adhesive tackiness agent, thus limits its application too.Market has also occurred some other viscose binders, as thermosol adhesive etc., but its resistance toheat is poor, and not oil resistant and organic solvent.
Summary of the invention
The object of the present invention is to provide Wood adhesive that a kind of excellent property, good waterproof performance and bonding force are strong and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Wood adhesive, and its component by mass percent proportioning is: organo montmorillonite 8% ~ 20%, dibutyl phthalate 5% ~ 10%, polyvinyl alcohol 10% ~ 15%, polyisocyanates 2% ~ 5%, glycerol 5% ~ 10%, copper azoles boron 4% ~ 8%, sodium lauryl sulphate 1% ~ 3%, distilled water 30% ~ 65%.
Described organo montmorillonite be surface through octadecyl dihydroxy ethyl ammonio methacrylate activation treatment and particle diameter at the sodium-based montmorillonite of 25nm ~ 75nm.
The polymerization degree of described polyvinyl alcohol is 1700 ~ 2000, alcoholysis degree is in 88% ~ 98% scope.
The preparation method of above-mentioned a kind of Wood adhesive, comprises the following steps:
(1), each component is taken by weight ratio;
(2), organo montmorillonite, dibutyl phthalate and distilled water are added in agitator, stir 10 ~ 30min, then polyvinyl alcohol and polyisocyanates is added, stir 10 ~ 15min, add glycerol, copper azoles boron, sodium lauryl sulphate again, stir 10 ~ 15min, obtain a kind of Wood adhesive of the present invention.
The invention has the beneficial effects as follows, the present invention has excellent property, water resistance is good, bonding force is strong and the advantage such as asepsis environment-protecting, and good heat resistance, and cost is low, and preparation technology is simple.
