Description
Technical field
The present invention relates to a kind of preparation method of the viscous seam agent of assembled architecture wallboard for expanding waterproof.
Background technology
Assembled architecture is built with the advantages that its production efficiency is high, superior, short construction period, good environmental benefit and tradition
Building mode and comparing has the advantages of prominent.
Assembled architecture wallboard is fixed in steel skeleton building by high intensity screw, and the seam crossing of wallboard and wallboard may
The hidden danger such as intensity difference, infiltration, not sound insulation be present.Conventional processing mode is often sealed using chemical glue, or using common
Cement smears seam filling.The former has toxicity and poor durability, and the latter's waterproof soundproof effect is undesirable, and stress is easily dry and cracked de-
Fall.Therefore, a kind of have strong cementability, waterproof, the viscous exploitation for stitching agent of closely knit, good endurance the assembled architecture wallboard of filling very
It is necessary.
The content of the invention
The purpose of the present invention is that to solve the above problems and provides a kind of assembled architecture wallboard for expanding waterproof
The preparation method of viscous seam agent, the viscous seam agent expansion function after preparation enable to the gap filling between wallboard and wallboard more close
Real, sound insulation and waterproof effect are more preferable.
The present invention is achieved through the following technical solutions above-mentioned purpose：A kind of viscous seam of the assembled architecture wallboard for expanding waterproof
The preparation method of agent, comprises the following steps：
Step 1：Metal iron powder, calcium lignosulfonate, benzoic acid, isopropanol are put into agitating device, stirred；
Step 2：The mixture being stirred is put into evaporating dish, and isopropanol therein volatilized in vacuum drying chamber
Remove, crush to obtain dried powder by remaining solid matter using pulverizer；
The dried powder of step 2 is taken, with Portland cement, calcium sulphoaluminate clinker, bentonite, hydroxypropyl methyl
Cellulose, redispersable latex powder, polyvinyl alcohol instant dissolving glue powder, water reducer, magnesia are well mixed simultaneously in dry-powder mixer
It is sealed.
Temperature in described vacuum drying chamber is 30 degrees Celsius, vacuumizes 0.1 atmospheric pressure.
Described bentonite is modified alta-mud.
Described bentonite is that modified alta-mud preparation method is as follows：
Step 1, sodium bentonite is dispersed in water, stirs 5h at room temperature, supernatant is taken after standing 8h；
Step 2, CMS is dissolved in 60 DEG C of heating water bath processing 1h in 3 parts of acetums；
Step 3, by the above-mentioned CMS acetum handled well with per minute 30 drop speed be added dropwise to it is swollen
Moisten in native supernatant, continue stirring reaction 5h under 60 DEG C of water-baths；
Step 4, it is then centrifuged for and is washed with pure water, finally shakes and be dispersed in again in 200ml ultra-pure waters under vacuum tank, obtained
CMS-bentonite；
Step 5, manganese powder is subjected to hot alkali treatment：Manganese powder is handled into 1h first under hot-air to go out to sweep impurity, then turned
Move on in 10 parts of NaOH solution and soak 1h；
Step 6 and then the zinc powder for crossing hot alkali treatment are added in solution and stir 1h at room temperature；
Step 7, above-mentioned solution is transferred in ptfe autoclave, titanate coupling agent is then added dropwise；
Step 8, by the manganese solution handled well be added in above-mentioned CMS-bentonite solution then be transferred to it is micro-
1h is reacted under ripple reactor；Vacuum drying, you can obtained modified alta-mud.
The present invention is applied to the gap filling between assembled architecture wallboard and wallboard, and the viscous seam agent of preparation has expansion energy
Power, material do not shrink, are bonded firm, waterproof, sound insulation, prevent mould, lower-cost advantage；Because the expansion function of material can
To cause the gap filling between wallboard and wallboard more densely cross-linked, sound insulation and waterproof effect are more preferable.
