Abstract
The invention discloses a slow-speed drying and curing glue for pasting of invoices. The glue contain silica/polyvinyl alcohol hybrid material or a metal oxide/polyvinyl alcohol hybrid material, as well as high-specific-area powder, and the preparation method comprises the following steps: feeding mixed solvent of methanol, ethanol and water into a reaction kettle, and heating to 65-85DEG C; adding a precursor, dropwise adding a certain amount of diluted hydrochloric acid or diluted alkaline solution, and controlling the pH of the system to be 1-6; slowly adding polyvinyl acetate solid, stirring until the dissolving is thorough, and continuously preserving heat and reacting for 1-3h; adding the high-specific-area powder, stirring and fully reacting, cooling and standing to room temperature, to obtain the slow-speed drying and curing glue. After the glue is coated and used, the adhesion power is strong, and the drying and curing speed is slow.
Description
Technical field
The present invention relates to a kind of glue, particularly relate to a kind of invoice and paste glue using dry solidification at a slow speed and preparation method thereof.
Background technology
Routine work and life in, often need to use glue and paste various article, such as file, invoice, books etc.Most of glue, such as 502 glue are all the glue of quick-dry type, and once coating, several seconds or tens of second just can dry solidifications, thus two objects pasted will be needed tightly to stick together.And once run into the situation needing to tear or again paste, then due to glue completely the dry object (such as page, invoice etc.) being easy to paste of solidification damage, at this time we just need a kind of dry solidification velocity ratio more slowly glue to meet this demand.
In prior art, the research about glue or sizing agent is very ripe, especially quick-drying, wink dry type glue, and slow curing type glue is the product needing big area to bond for plastics, building board etc. mostly.According to the retrieval of applicant, find the glue of the dry solidification at a slow speed not yet having suitable routine work and life to use on the market.
Summary of the invention
The invention provides a kind of invoice and paste the glue using dry solidification at a slow speed, this kind of glue is after coating uses, and adhesive power is strong and dry solidification speed is slow.
For achieving the above object, the present invention adopts following technical scheme:
The glue using dry solidification at a slow speed pasted by invoice, and it contains silicon-dioxide/polyvinyl alcohol hybrid material or metal oxide/polyvinyl alcohol hybrid material.
Preferably, described metal oxide is one or more arbitrary combination in the oxide compound of titanium, zirconium, tin, aluminium.
Preferably, described glue is also containing high-ratio surface powder-deposit, and the specific surface area of this high-ratio surface powder-deposit is not less than 500 m
2/ g.
Preferably, described high-ratio surface powder-deposit is one or more arbitrary combination in magnesium aluminum silicate, magnesium aluminometasilicate, aluminium hydroxide, thermal silica, hydrotalcite.
Prepare described invoice and paste the method using the glue of dry solidification at a slow speed, comprise the following steps:
(1) mixed solvent of methyl alcohol, second alcohol and water is thrown in reactor, be warming up to 65 ~ 85 DEG C;
(2) add presoma, drip a certain amount of dilute hydrochloric acid or dilute alkaline soln, the pH of the hierarchy of control is between 1 ~ 6;
(3) slowly add polyvinyl acetate (PVA) solid, stir until dissolve completely, and continue insulation reaction 1 ~ 3h;
(4) add high-ratio surface powder-deposit, stirring reaction is complete, cools and leaves standstill to room temperature, obtains invoice of the present invention and pastes the glue using dry solidification at a slow speed.
Preferably, in the mixed solvent of described methyl alcohol, second alcohol and water, the mass ratio of first alcohol and water is 1:20 ~ 50, and the mass ratio of second alcohol and water is 1:1 ~ 30; The total mass of mixed solvent and the mass ratio of polyvinyl acetate (PVA) solid are 2 ~ 9:1.
Preferably, described dilute alkaline soln can be dilute NaOH solution, weak ammonia or rare KOH solution, also can be that other have other dilute alkaline solns of similarity.
Preferably, described presoma is one or more arbitrary combination in tetraethoxy, Union carbide A-162, butyl (tetra) titanate, zirconium oxychloride, tin tetrachloride, aluminum chloride, titanium tetrachloride.
Preferably, described powder is one or more arbitrary combination in magnesium aluminum silicate, magnesium aluminometasilicate, aluminium hydroxide, thermal silica, hydrotalcite.
Preferably, the mass ratio of described presoma and polyvinyl acetate (PVA) solid is 1:10 ~ 30.
Preferably, the mass ratio of described powder and polyvinyl acetate (PVA) solid is 1:50 ~ 100.
Preferably, the stirring velocity of step (4) is 500 ~ 1500 rpm.
According to technical scheme of the present invention, presoma and polyvinyl acetate (PVA) generation cohydrolysis, the former is hydrolyzed the Si oxide chain or metal oxide chain that generate containing a lot-OH, and the latter generates the polyvinyl alcohol containing some amount-OH; Both can pass through the dehydration condensation between-OH and link together in the process of hydrolysis, namely organism polyvinyl alcohol and Si oxide or inorganic, metal oxide have linked together, and generate silicon-dioxide/polyvinyl alcohol hybrid material or metal oxide/polyvinyl alcohol hybrid material.For example, that utilize tetraethoxy correspondence to generate is SiO
2/ polyvinyl alcohol hybrid material, that utilize butyl (tetra) titanate correspondence to generate is TiO
2/ polyvinyl alcohol hybrid material, that utilize tin tetrachloride correspondence to generate is SnO
2/ polyvinyl alcohol hybrid material, other presomas are similar.
Due to containing silicon-dioxide/polyvinyl alcohol hybrid material or metal oxide/polyvinyl alcohol hybrid material, polyvinyl alcohol in glue obtained like this slowly comes off from Si oxide or metal oxide and plays bonding effect, simultaneously because silicon-dioxide/polyvinyl alcohol hybrid material or metal oxide/polyvinyl alcohol hybrid material have stronger wetting ability, hybrid material inside attracts to combine a certain amount of water molecules, the volatilization of this kind of internal water molecule is very slow, and these two kinds of reasons make the glue that obtains can dry solidification slowly.
In addition, the present invention also with the addition of the powder of high-specific surface area in glue, its effect is the specific surface area utilizing it huge, the polyvinyl alcohol freely slowly come off and internal water molecule are attracted to its pore texture, delay the time that polyvinyl alcohol plays adhesive action further, and make it after a very long time also containing moisture, can not solidify by complete drying, some occasion is facilitated to use, such as paste a/d, if find in a few days, mistake easily can tear it down invoice re-posted, and can not because dry solidification causes damaging invoice completely in the process of tearing as common glue.
And, situation about being pasted not strongly can't be there is in product of the present invention because of its dry solidification overlong time, this is because in the hybrid structure of silicon-dioxide/polyvinyl alcohol hybrid material or metal oxide/polyvinyl alcohol hybrid material, Si oxide chain or metal oxide chain contain a lot-OH, it has attracted polyvinyl alcohol molecule and internal water molecule on the one hand, provide the initial bonding strength suited the requirements on the other hand, thus ensure that the article such as the invoice just having started to paste can be bonded together more securely.
