The present invention at least includes following beneficial effect：
(1) starch adhesion agent addition agent of the invention is nontoxic, odorlessness, does not result in environmental pollution, does not interfere with human body
Health.The present invention, which is added to after amidin obtained amylum adhesive, has stronger cohesive force, fast from dry speed, moisture absorption
Property weak, water resistance it is strong, and amylum adhesive is formed stable suspension, will not settle, extend storage time.
(2) the first component of the invention is made up of ammonium persulfate and sodium carbonate peroxide, and the first component adds amidin
Sodium carbonate peroxide decomposites hydrogen peroxide quickly afterwards, and hydrogen peroxide aoxidizes the hydroxyl on starch molecular chain, and makes starch molecule
Degraded, this reduces the viscosity of amidin, improves the mobility of amidin, improves thermo qualitative, strengthens
Anti-settling ability, the speed that ammonium persulfate decomposites hydrogen peroxide is slower, and this has just slowed down the oxidation rate of starch, will not make
Excessively, starch oxidation can excessively make obtained amylum adhesive formation gel and lose cementitiousness starch oxidation.In the present invention
Ammonium persulfate and the preferred ratio of sodium carbonate peroxide are 1:1.2, the ratio both can guarantee that enough hydrogen peroxide to aoxidize shallow lake
Powder, and it is unlikely to make starch oxidation again excessively, and also the ammonium persulfate of residual can also trigger Lauxite and ethyl vinyl acetate second
Modification of the alkene ester resin to starch molecular chain, without addition initiator in addition.
(3) the second component of the invention is made up of Lauxite and ethylene-vinyl acetate resin, in drawing for ammonium persulfate
Give, the active methylol on Lauxite can be combined with the residual hydroxyl in starch molecule, on ethylene-vinyl acetate resin
Active Hydrogen Energy combined with the carbonyl aoxidized in starch molecule on obtained aldehyde radical and Lauxite, so, in Lauxite and
In the presence of ethylene-vinyl acetate resin, starch molecule forms network structure, and this just greatly improves the bonding of adhesive
Ability, and the reduction of hydroxyl reduces the hydrophily of starch molecule, and this adhesive allowed for has stronger water resistance, and
And it is difficult moisture absorption softening.The weight ratio of Lauxite and ethylene-vinyl acetate resin is with 2.5:1 is advisable, and fits Starch formation
The network structure of degree, without excessive, because ethylene-vinyl acetate resin can be combined with starch and Lauxite, once ethene-
Vinyl acetate resin can excessively increase the viscosity of adhesive, have a strong impact on the mobility of adhesive, or even make adhesive can not
Use.
(4) the 3rd component of the invention by bentonite, hydrotalcite, calcium carbonate, alum, polyvinyl alcohol, sodium tripolyphosphate and
Sodium carboxymethylcellulose is constituted, and bentonite, hydrotalcite, calcium carbonate, which are added in amylum adhesive, can effectively improve starch adhesion
The certainly dry speed of agent, wherein hydrotalcite has non-hygroscopic well, beneficial to moisture evaporation.Wherein, bentonite, hydrotalcite and carbon
The preferred weight ratio of sour calcium is 1:2:1, experiment is found under the ratio, and bentonite, hydrotalcite and calcium carbonate not free settling make shallow lake
Powder adhesive from dry fastest, and hydrotalcite also has certain effect for killing bacterium and microorganism, can be effective
Prevent amylum adhesive from going bad, effectively extend the storage time of amylum adhesive.In order to further improve amylum adhesive
Inorganic dispersant sodium tripolyphosphate and macromolecule dispersing agent sodium carboxymethylcellulose are also added into stability, the present invention, wherein
Sodium tripolyphosphate has extremely strong complexing, with reference in solid particle, (solid particle includes starch granules, bentonite, neatly
Stone and calcium carbonate powder particle), the dissolubility of solid particle is improved, sodium carboxymethylcellulose is a kind of macromolecule dispersing agent,
With more carboxyl, these carboxyls are connected with molecular solids, make solid particles surface powered, make to arrange mutually between solid particle
Reprimand, it is impossible to condense and settle, the preferred weight ratio of sodium tripolyphosphate and sodium carboxymethylcellulose is 4 in the present invention:7, at this
Under ratio, two kinds of dispersal mechanisms can be given full play to, amylum adhesive is not settled completely, can be preserved for a long time.
(5) during the 3rd component is prepared, when adding bentonite, hydrotalcite and calcium carbonate, energization processing is carried out,
And positive and negative electrode is exchanged twice, this is the ion in sodium tripolyphosphate and sodium carboxymethylcellulose is filled in the solution using electric current
It is scattered, and be dispersed in around solid particle, once the 3rd component is added in starch solution, you can rapidly with solid
Burl is closed, and is acted.
(6) when preparing amylum adhesive using starch adhesion agent addition agent, with ultrasonic amplitude after the 3rd component is added
According to this is, in order to promote Motion of solid particle, and fully to be combined with dispersant, improves the dispersion effect of dispersant.And ultrasound
Ripple has stronger energy, can interrupt, modified starch strand, reduces the viscosity of adhesive, amylum adhesive is more suitable for fortune
With.
