Technical field
The invention belongs to the preparation field of adhesive, and in particular to a kind of system of maleic anhydride dry method esterification starch adhesive
Preparation Method.
Background technology
Adhesive is under given conditions by being glued chemical reaction by the two-layer material that even multilayer laminate is bonded together
Material.Due to the processing characteristic of wood materials, adhesive is by large-scale application in Wood industry.Now, the adhesive based on formaldehyde
Such as phenolic resin, Lauxite etc. are mainly for the production of composite wooden material.But formaldehyde base adhesive is not environmentally friendly
Product, World Health Organization (WHO) confirm that formaldehyde is human carcinogen.And formaldehyde base adhesive derives from non-renewable oil
Resource, therefore composite wooden material industry is in the predicament for finding the environmentally friendly adhesive from Renewable resource.
Starch source is extensive, cheap, environmental protection is renewable, is widely used in the neck such as clothing, papermaking, printing and dyeing and adhesive
Domain.But pure starch has many weak points, such as poor water resistance, poor mechanical property, poor fluidity, dry speed as adhesive
Degree is slow, adhesive strength is poor, needs to be modified which by physics or chemistry method, could meet different application field
Performance requirement.Isocyanates have excellent bonding property and water resistance, for starch conversion, but it is expensive.Starch
Contain glycosidic bond and activity hydroxy in molecule, chemical reaction can occur with many materials, be the base that chemical modification is carried out to starch
Plinth.Corn starch gluing agent is one of kind of modified starch, is excellent binding agent, of many uses.At present, starch adhesive
Production method have an alkalization method, there is processing technology in gelatinizing method, oxidizing process and with other high polymer monomer grafting copolymerization processes etc.
Grow, solids content is low, and drying time is long, resting period, short grade was not enough.
The content of the invention
The present invention provides a kind of preparation method of maleic anhydride dry method esterification starch adhesive.
The present invention is achieved by the following technical solutions.
The preparation method of maleic anhydride dry method esterification starch adhesive, comprises the steps of：
（1）Maleic anhydride is placed in exsiccator, under room temperature, places that 24 h are standby, obtain the maleic anhydride that constant humidity was processed；
（2）By starch and step（1）The maleic anhydride mix homogeneously that the constant humidity for obtaining was processed, wherein, the quality of maleic anhydride
The 1%-7.5% of starch quality is accounted for, it is standby in agitator stirring reaction 30min, obtain the starch of dry method esterification；
（3）The starch of dry method esterification is weighed, 10% amidin is configured to, is transferred to and is equipped with mechanical agitation oar and temperature
In the four-hole boiling flask of meter, stirring is opened, 70-90 DEG C is warming up to, with sodium hydroxide solution regulation system pH=7.5-8.5, reacted
30min, addition account for the polyvinyl alcohol of the starch quality 6% of dry method esterification and account for the persulfuric acid of the starch quality 2% of dry method esterification
Ammonium salt solution, with hydrochloric acid regulation system pH=3-4, reacts 1h, then heats to 55 DEG C, and addition accounts for the starch quality of dry method esterification
0.2% sodium tetraborate, reacts 30min, naturally cools to room temperature, discharges, and maleic anhydride dry method esterification starch adhesive is obtained.
Preferably, above-mentioned starch is corn starch.
Preferably, step（2）The speed of middle stirring is 2000rpm.
Preferably, step（3）The concentration of middle sodium hydroxide solution is 1mol/L.
Preferably, step（3）The mass concentration of middle ammonium persulfate solution is 10%.
Advantages of the present invention：
The present invention is simple to operate, and technological process is short, produces low, and the adhesive heat stability for preparing is good, and solid content is high, can carry
The bonding strength and resistance to water of high plywood.
