Abstract
The invention discloses a high-strength and waterproof wood adhesive and a preparation method thereof. The high-strength and waterproof wood adhesive is prepared from polyvinyl alcohol, starch, hydrogen peroxide, sodium hydroxide, ammonium persulfate, ferrous sulfate, borax and a deionized water material. According to the high-strength and waterproof wood adhesive and the preparation method thereof, a main adhesive material is prepared through compounding of polyvinyl alcohol and the starch which are cheap and easy to obtain, the wood adhesive is prepared with low-price and good-performance hydrogen peroxide and ammonium persulfate as oxidizing agents and borax as a cross-linking agent, and high-toxicity chemical agents are avoided. The prepared adhesive has higher adhesion strength and water resistance while compared with other polyvinyl alcohol adhesives. The preparation process is simple and easy to control.
Description
Technical field
The invention belongs to adhesive technical field, be specifically related to a kind of high strong water resistant based Wood Adhesives and preparation method thereof.
Background technology
Polyvinyl alcohol have preferable strong adherence, glued membrane intensity transparent, oil resistant, solvent resistant high, tough and tensile, corrosion-resistant,
Wear-resisting, and there is barrier properties for gases relatively and heat stability, it is adaptable to wood-based plate, core-board, plywood, particieboard, highly dense
Spend the bonding of fibre board etc., have the feature that manufacturing process is simple, curing rate is fast.But, the high molecular spy of water-soluble polyhydroxyl
Matter makes PVA based Wood Adhesives have poor water resistance, thus limits its range of application.At present, people are frequently with adding
Add formaldehyde, butyraldehyde or crotonaldehyde and make Polyvinyl acetal, add toluene di-isocyanate(TDI) or triphenyl methane three Carbimide.
Ester carries out cross-linking modified method to improve resistance to water and the adhesive property of polyvinyl alcohol glue to polyvinyl alcohol, achieves comparison bright
Aobvious modified effect, but due to aldehydes and the penetrating odor of isocyanates and toxicity, its application is affected.It addition, also can adopt
Resistance to water and the mechanical property of polyvinyl alcohol is improved with adding the method such as wood fibre, nano clay, but these method of modifying
There is operating procedure more complicated, introduce the relatively costly problem of raw material.
Summary of the invention
A kind of high strong water resistant based Wood Adhesives of the present invention and preparation method thereof.Technical scheme is as follows:
A kind of high strong water resistant based Wood Adhesives, it is characterised in that be made up of the raw material of following parts by weight:
Polyvinyl alcohol 40-50 part
Starch 20-30 part
Hydrogen peroxide 2-6 part
Ammonium persulfate. 1-3 part
Borax 1-3 part
Sodium hydroxide 2-5 part
Ferrous sulfate 1-3 part
Deionized water 20-40 part.
Wherein, the method preparing high strong water resistant based Wood Adhesives, step is as follows:
(1) in a beaker, add deionized water, be heated under 50 DEG C, stirring being slowly added to starch；With mass fraction it is
The pH value of starch fluid is adjusted to 9-10 by the sodium hydroxide solution of 30%；
(2) hydrogen peroxide and ferrous sulfate are added, lower oxidation reaction 0.5h of insulation；It is subsequently adding the sodium hydroxide solution of 30%,
Gelatinizing 0.5h at 60 DEG C, obtains gelatinized corn starch, standby；
(3) in reactor, add deionized water, under agitation, be slowly added to polyvinyl alcohol, be warming up to 80 DEG C of insulated and stirred,
Until polyvinyl alcohol is completely dissolved；It is cooled to 55 DEG C, adds Ammonium persulfate. while stirring, aoxidize 20 min；
(4) add the gelatinized corn starch prepared, after stirring, be warming up to 75 DEG C, add borax soln, react 30min, with 30%
The pH value of glue is adjusted to 6～7 by sodium hydroxide solution, is warming up to 85 DEG C and continues reaction, when in bottle, glue is faint yellow semi-transparent
Time bright, cooling discharge, to obtain final product.
Beneficial effects of the present invention: high strong water resistant based Wood Adhesives of the present invention and preparation method thereof, uses cheap and easy to get
Starch and polyvinyl alcohol carry out compounding and prepare main sizing material, the hydrogen peroxide excellent with the low property of valency and Ammonium persulfate. as oxidant, boron
Sand is cross-linking agent, prepare adhesive for wood, it is to avoid use the chemical reagent of high poison.Prepare adhesive compared to other
Polyvinyl alcohol gluing agent, has higher bonding strength and water resistance.And preparation technology is simple, is easily controlled.
