Public glue is more to be prepared using high molecular weight water soluble polymer polyvinyl alcohol as raw material, in order to strengthen the cementability of product, is gathered
Modifying agent would generally be added in vinyl alcohol, conventional method is that formaldehyde is added in polyvinyl alcohol, passes through formaldehyde and polyvinyl alcohol
In hydroxyl react and obtain polyvinyl formal product, but the trip unfavorable to health can be remained in this kind of product
From formaldehyde, and free formaldehyde content is often exceeded, is not only detrimental to health, and larger pollution is caused to environment；Meanwhile, pass
Glue unite in the preparation because the modifying agent of selection is more and expensive so that the production cost of product is higher, and many property
It can could not meet Standard.
The content of the invention
For the demand, the invention provides a kind of environment-friendly type office glue and preparation method thereof, the office glue
Water preparation method is simple, easily implements production, without formaldehyde and production cost is low, and its integrated performance index is superior to Standard.
The present invention is a kind of environment-friendly type office glue and preparation method thereof, and described glue is by poly-vinyl alcohol solution and friendship
Connection agent modified-reaction is prepared from, and described preparation method comprises the following steps：a）Produce poly-vinyl alcohol solution, b）It is cross-linking modified
Processing, c）Finished product and detection.
In a preferred embodiment of the present invention, described poly-vinyl alcohol solution by polyvinyl alcohol and deionized water in mass ratio
1：10 are formulated.
In a preferred embodiment of the present invention, described crosslinking agent is titanium in metatitanic acid aqueous solution of ester, the metatitanic acid aqueous solution of ester
The mass percent of acid esters is 6.5%.
In a preferred embodiment of the present invention, the consumption of described crosslinking agent accounts for the quality percentage of poly-vinyl alcohol solution consumption
Than for 2.4%.
In a preferred embodiment of the present invention, described step a）In, producing for poly-vinyl alcohol solution is by polyvinyl alcohol
Add into deionized water complete in 80 DEG C of constant temperature stirring 5min dissolvings.
In a preferred embodiment of the present invention, described step b）In, the reaction condition of cross-linking modified processing is：Reaction
Liquid pH value 6.2,60 DEG C of reaction temperature, reaction time 45min.
Present invention is disclosed a kind of environment-friendly type office glue and preparation method thereof, office glue preparation method letter
It is single, easily implement production, without formaldehyde and production cost is low, its integrated performance index is superior to Standard.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Fig. 1 is the process step diagram of environment-friendly type office glue preparation method of the embodiment of the present invention.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1 is the process step diagram of environment-friendly type office glue preparation method of the embodiment of the present invention；The glue is by polyethylene
Alcoholic solution is prepared from crosslinking agent modified-reaction, and described preparation method comprises the following steps：a）Produce poly-vinyl alcohol solution,
b）Cross-linking modified processing, c）Finished product and detection.
The environment-friendly type office glue that the present invention is referred to, as crosslinking agent, using polyvinyl alcohol as raw material, is led to using titanate esters
It is prepared by the cross-linking reaction for crossing polyvinyl alcohol and titanate esters.Wherein, titanate esters are a kind of reactivity very high crosslinking agent, energy
Reaction is crosslinked with the water soluble polymer of hydroxyl and amino；The titanate esters crosslinking agent reacts with polyvinyl alcohol, with anti-
Answer temperature low, the characteristics of time is short, the viscosity of reaction product increases with the rise of reaction temperature, with the increase of titanate esters consumption
And increase；The office glue that the titanate esters crosslinking agent is prepared with polyvinyl alcohol crosslinked reaction is with traditional polyvinyl formal
Glue is compared, without formaldehyde, Environmental Safety, and production cost is low, and reaction condition is gentle.
Embodiment
Specific preparation method is as follows：
a）Poly-vinyl alcohol solution is produced, specific preparation process is：First equipped with agitating device, reflux condensing tube, dropping funel
With heater from container, a certain amount of deionized water is added, under agitation, a certain amount of polyvinyl alcohol is added, its
In, the quality proportioning of polyvinyl alcohol and deionized water is 1：10；Then heat to 80 DEG C of constant temperature stirring 5min, you can be completely dissolved
Polyvinyl alcohol, produces poly-vinyl alcohol solution.
b）Cross-linking modified processing, specific preparation process is：A certain amount of titanate esters are dissolved in deionized water first and being obtained
Titanate esters mass percent is 6.5% metatitanic acid aqueous solution of ester, then by step a）In it is cold from the poly-vinyl alcohol solution in container
But to 60 DEG C, and the pH value of solution is adjusted to 6.2 with appropriate hydrochloric acid；Take again
The metatitanic acid aqueous solution of ester that poly-vinyl alcohol solution mass percent is 2.4% is accounted for, polyvinyl alcohol is added drop-wise to by dropping funel molten
In liquid, dropwise reaction 45min, you can obtain titanate esters and polyvinyl alcohol crosslinked product.
c）Finished product and detection, by step b）In the titanate esters produced and polyvinyl alcohol crosslinked product be cooled to room temperature, then from
Blowing produces office glue finished product from container.Through performance detection, the content of formaldehyde of the office glue is 0, and outward appearance is in
Clear viscous shape, viscosity is 1640mPas, and non-volatile content is 8.6%, and heat resistance is rendered as existing without caking, layering etc.
As cold tolerance is rendered as without caking, mobility without significant change, therefore properties are superior to Standard.
Present invention is disclosed a kind of environment-friendly type office glue and preparation method thereof, office glue preparation method letter
It is single, easily implement production, without formaldehyde and production cost is low, its integrated performance index is superior to Standard.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those skilled in the art disclosed herein technical scope in, the change that can expect without creative work or
Replace, should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be limited with claims
Fixed protection domain is defined.
