Abstract
The invention discloses a bonding agent and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing a nano-carbon material and raw materials of the bonding agent, carrying out screening filtration after fine grinding, and conducting high-temperature gelatinization on the filtrate, so as to obtain the bonding agent. The prepared bonding agent can adsorb harmful gas, has an anti-mildew function, can improve the bonding strength between a substrate and various kinds of wallpaper, and can improve the tear resistance of the wallpaper.
Description
Technical field
The present invention relates to adhesive techniques field, particularly relate to wallpaper adhesive techniques field, particularly the organic wallpaper binding agent of vegetable active, the preparation method of the wallpaper binding agent being feature with the effect of its physical properties or generation.
Background technology
In current Decoration Industry, house decorative material and furniture use paint, filler etc. all contain organic harm compositions such as formaldehyde, benzene, ethanol usually, and these volatile components distribute obnoxious flavour, can cause room air pollution.Therefore, the binding agent of indoor wallpaper adopts the binding agent of environment-friendly type mostly, as liquid starch glue, glutinous rice glue or powder.
Because existing inner wall of building is fitted up, typically use putty powder and use the talcum powder, white stone powder etc. of putty glue to be coated with and scrape on metope, the sealer coat that this coating formation cannot permeate.When pasting wallpaper on the wall, wallpapers etc. penetrate into putty layer the moisture content in air, moisture content is kept off between wallpaper and wallpaper glue by putty layer, when indoor air humidity is large, metope can form one deck droplet, even pools current, if things go on like this, can cause wallpaper mouldy, come off, and then breed bacteria, makes people cause a disease.
In addition, mostly there is bad adhesion, be unfavorable for the defects such as construction in existing wallpaper binding agent.
The Environment-friendlywallpaper wallpaper binding agent manufacture method of prior art, its manufacture method is as follows: 1) soaked by glutinous rice; 2) slurry is worn into; 3) mix with other additives; 4) high temperature gelatinization; 5) adding preservative agent.But the binding agent that prior art preparation method obtains can not solve the mouldy problem of above-mentioned wallpaper completely.
In order to solve the above-mentioned technical problem that existing wallpaper binding agent exists, the present invention comes therefrom.
Summary of the invention
The present invention seeks to the shortcoming of easy mouldy, the bad adhesion of binding agent in order to solve prior art, a kind of binding agent and preparation method thereof be provided, improve the cohesive force of matrix and various wallpaper, while adsorbable obnoxious flavour and there is mildew-proof function.
For solving the problem, technical scheme provided by the invention is: a kind of binding agent, and it prepares by the following method,
(1) binding agent raw material and water are mixed in proportion, defibrination after soaking, obtains glue;
(2) nano-sized carbon joined in aforesaid glue, after mixing, fine grinding obtains slow setting glue;
(3) by slow setting glue after screen filtration, carry out high temperature gelatinization, obtain binding agent.
Described binding agent raw material is selected from wherein one or more such as glutinous rice, plant amylum, but is not limited only to this.Described plant amylum comprises all kinds of cereal, and as paddy rice, wheat, corn etc., can also comprise the starch such as beans, certainly, also comprise usual or other the plant amylum known of those skilled in the art.
Described nano-sized carbon is selected from wherein one or more such as CNT (carbon nano-tube), ultra micro carbon fiber, Graphene, mesoporous carbon, micro crystal graphite, Nano diamond, but is not limited only to this.
The nanometer carbon amounts of adding is the 0.1%-25% of glue weight, and the nanometer carbon amounts of preferably adding is the 1%-15% of glue weight.
The technical problem that a second aspect of the present invention will solve, be to provide the preparation method of foregoing adhesives, it comprises the steps:
(A) binding agent raw material and water are mixed in proportion, defibrination after soaking, obtains glue;
(B) join in glue by nano-sized carbon, after mixing, fine grinding obtains slow setting glue;
(C) slow setting glue is after screen filtration, carries out high temperature gelatinization, obtains described wallpaper binding agent.
The technical problem that a third aspect of the present invention will solve, is to provide the cohesive action of a kind of binding agent for wallpaper and inner wall of building.
The invention has the advantages that: the binding agent that the present invention prepares can have absorption obnoxious flavour, prevent mouldy effect, meanwhile, preparation method's technique of the present invention is simple, and controllability is good, easily realizes suitability for industrialized production.The present inventor finds when the nanometer carbon amounts of adding is the 1%-3.5% of glue weight, can reach/produce unforeseeable technique effect, as cohesive force increases, the consumption of metope of the same area binding agent used reduces about 10%, namely brush metope of the same area, the consumption of this binding agent is 90% of general consumption of binder, namely effectively can improve the cohesive force of matrix and various wallpaper, improve the tear resistance of wallpaper
Accompanying drawing explanation
Fig. 1 is the scanning electronic microscope SEM photo of the wallpaper binding agent that the embodiment of the present invention 1 prepares.
Fig. 2 is the schematic flow sheet of binding agent preparation method of the present invention.
Embodiment
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are not limited to for illustration of the present invention limit the scope of the invention.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
Embodiment 1
(1) prepare glutinous rice glue: sticky rice flour and water are put into stirrer by 1:8, stir 30min with the speed of 50rpm, after then leaving standstill 1-2h, continue to be stirred to evenly;
(2) in glutinous rice glue, add the CNT (carbon nano-tube) accounting for glutinous rice glue gross weight 1%-15%, stir 0.5-2.0h with the speed of 50rpm, then fine grinding obtains slow setting glue;
(3) the slow setting glue screen filtration of 300 orders or more is removed the uneven particle of dispersion, be then placed on 20min to 2h in 100-160 DEG C of high-temperature steam Sealing furnace, after cooling, obtain wallpaper binding agent.
Wallpaper binding agent is torn after dried coating film between wallpaper and body of wall, electronic scanning test is carried out to its interface, obtain SEM photo, CNT (carbon nano-tube) and glutinous rice glue Homogeneous phase mixing are described, in figure, part CNT (carbon nano-tube) is connected between wallpaper and body of wall, can effectively stop wallpaper produce mould and come off.
Embodiment 2
(1) prepare glutinous rice glue: glutinous rice is soaked 3h in high purity water, add clear water after then wearing into slurry, in slurry, the solid content of glutinous rice is 10%-20%, obtains glutinous rice glue after crossing 300 eye mesh screens;
