Abstract
The invention provides a starch-based wood adhesive and a preparation method and application thereof, and belongs to the technical field of adhesive. In the invention, a starch adhesive for woods with good property is prepared by performing acidolysis and gelatinization on starch serving as raw materials, grafting, copolymerizing and modifying the starch by using two monomers of vinylacetate and butyl acrylate under the condition of adding an emulsifier, and adding an accessory ingredient after lowering the temperature. The adhesive prepared by the preparation method has the advantages of good preservation stability, high bonding strength, milky white and glossy color and the like, and can be applied to decoration of woods and bonding of artificial plates and glued plates.
Description
Technical field
A kind of starch-base timber adhesive and its production and application belongs to the tackiness agent preparing technical field.
Background technology
Starch have recyclability, pollution-free, cost is low, biodegradable, starch is used for the bonding of fluting board etc. and has had certain history, and has realized industrialized production.There are shortcomings such as rate of drying is slow, bonding strength is low, poor water resistance, color jaundice in traditional amylan, has limited its application in wood adhesive.Having proposed a kind of employing starch among the Chinese patent CN1687279A " a kind of preparation method of starch glue for lumber " is main raw material, carries out acidolysis, oxidation, grafting, copolymerization and modification processing, adds the technology that certain auxiliary agent prepares amylan at last.Advantages such as that the amylan that this prepared goes out has is with low cost, environmental protection, the bonding strength of amylan has reached national standard, but its outward appearance, bonding strength, water tolerance are still waiting to improve, in the hope of obtaining industrialized application.The present invention improves on the preparation technology basis of Chinese patent CN1687279A, comprise that mainly adding emulsifying agent improves the storage stability of tackiness agent and adopt butyl acrylate to carry out copolymerization and improve cohesive strength, can prepare that the outward appearance milky white is glossy, good fluidity, cohesiveness is strong, storage stability is good starch-base timber adhesive.
Summary of the invention
The purpose of this invention is to provide the starch-base timber adhesive that a kind of appearance milky white is glossy, cohesiveness is strong, storage stability is good.
The basic recipe tabulation by weight of described starch-base timber adhesive is:
Starch 100g
Ammonium persulphate 1-2g
Emulsifying agent 1-3g
Vinyl acetate 80-110g
Butyl acrylate 10-14g
Polyvinyl alcohol 10-20g
Urea 10-20g
Softening agent 5-10g
Tributyl phosphate 2-4g
Described starch is a kind of or its combination in W-Gum, waxy corn starch, tapioca (flour), yam starch or the wheat starch.
Described starch water is mixed with the starch milk that mass concentration is 25 g/100g ~ 40 g/100g.
Described polyvinyl alcohol water is configured to the solution of mass concentration 10 g/100g.
The model of described polyvinyl alcohol can select 1799,2499,2099 or 1788 for use.
Described emulsifying agent can be selected cationic emulsifier, anionic emulsifier and nonionic emulsifying agent for use.
Any among the preferred OP of described emulsifying agent, OP-10 and the sodium lauryl sulphate.
Described softening agent is glycerine or phthalate.
Every performance of this starch-base timber adhesive all is better than the starch-base timber adhesive of ordinary process preparation, especially storage stability is greatly improved, and the cost of this tackiness agent is lower than the common white latex, can be widely used in aspects such as timber decoration, wood working, wood-based plate.
The technical problem that the present invention also will solve provides a kind of preparation method of above-mentioned starch-base timber adhesive.
For solving the problems of the technologies described above, technical scheme of the present invention is: mix with emulsifying agent and polyvinyl alcohol after the starch acidolysis gelatinization pre-treatment, again respectively with vinyl acetate and butyl acrylate modification by copolymerization, auxiliary agent is added in cooling back, finally obtains a kind of starch glue for lumber stick of excellent property.
Described modified technique is for comprising the steps:
(1) be raw material with starch, being mixed with mass concentration is the starch milk of 25 g/100g ~ 40 g/100g;
(2) add the sodium hydroxide of using lower concentration under 60 ℃ of conditions of hydrochloric acidolysis behind acidolysis 40 min ~ 60 min and regulate pH to 4 ~ 5.5;
(3) be warming up to 80 ℃ ~ 90 ℃ gelatinization 30 min ~ 60 min, be cooled to 60 ℃ after, add initiator ammonium persulfate, emulsifying agent, protective colloid polyvinyl alcohol, and fully stir;
(4) slowly drip vinyl acetate, control grafting temperature is reacted 2h ~ 3h under 65-75 ℃ of temperature;
(5) after the vinyl acetate reaction drips end, slowly drip the butyl acrylate that accounts for starch butt quality 10% ~ 14%, reaction times 1h ~ 1.5h;
(6) reaction solution after the modification by copolymerization is neutralized to neutrality, 75 ℃ ~ 90 ℃ insulations that heat up are cooled to 50 ℃ behind 20min ~ 40min, add urea, glycerine or phthalate and tributyl phosphate, after mixing, cooling discharge, pack the finished product starch-base timber adhesive.
Described modified technique carries out under agitation condition.
Wherein add polyvinyl alcohol with tack that improves tackiness agent and the effect of playing protective colloid, add thinner urea to improve the flowability of tackiness agent, adding glycerine or phthalate is softening agent; The adding tributyl phosphate is a defoamer.
Add emulsifying agent before polyreaction, make emulsion pass through the micella nucleation and polymerization, emulsifying agent disperses better almost can cover all latex particles, and polyreaction is better carried out.In addition, emulsifying agent also can improve monomeric transformation efficiency, thereby has improved the cohesive strength of tackiness agent.Starch adhesive is because contain a large amount of starch, a large amount of hydrogen bonds that exist are the major causes that cause the starch adhesive unstability in the starch, and emulsifying agent has the effect of hydrogen bond destructive, and this hydrogen bond disrupting agent can be evenly dispersed in particle surface again, hydrogen bond action between can very effective destruction starch particle makes the storage stability of tackiness agent be greatly improved.
The starch-base timber adhesive of the present invention's preparation is compared with existing amylan, outward appearance, cohesive strength all are improved, especially storage stability improves obviously especially, and over-all properties approaches white glue with vinyl more, and has kept characteristics such as existing amylan is with low cost, environmental protection; Owing to added emulsifying agent in the preparation process, improved the transformation efficiency of graft copolymerization, improved the storage stability of starch adhesive simultaneously; Owing to adopt two kinds of monomers that starch is carried out grafting, copolymerization and modification in the preparation process, effectively raise the cohesive strength of amylan.
