Description
Technical field
The invention belongs to technical field of construction and decoration materials, and in particular to a kind of preparation method of the modified tapestry brick of building materials.
Background technique
Current tapestry brick is mainly using polymer emulsion as cementing material and flexible modifying agent, such material or system
Product have elasticity well and flexibility, but there is also two main problems: first is that tapestry brick is mainly used as the decorative layer of metope etc.
And protective layer, but organic bonding component therein can gradually be sent out within a short period of time under the action of light, heat, water and atmosphere
Raw aging and decomposition cause structure to be disintegrated to gradually lose effect, so that tapestry brick dusting or falling off.Second is that this flexibility
Tapestry brick organic component accounts for significant proportion, these component burning points are very low, very easy firing, and while burning can release a large amount of thorns
Swash property, toxic gas, further increases harm when fire occurs.Therefore, a kind of attapulgite modified tapestry brick is invented to building
Ornament materials preparation technical field has positive effect.
Summary of the invention
One, technical problems to be solved
The technical problem to be solved in the present invention is to provide a kind of building materials preparation methods of modified tapestry brick, described in solving
Technical problem.
Two, technical solution
To solve the technical problem, the technical scheme adopted by the invention is that: a kind of system of the modified tapestry brick of building materials
Preparation Method, specific preparation step are as follows:
It (1) is in mass ratio that 1:4 mixing is placed in a beaker by stearic acid and deionized water, 61-65 DEG C of heat temperature raising, and stir
Mix 20-30min, obtain stirring liquid, then by magnesium hydroxide and aluminium hydroxide be in mass ratio 1:2 mixed grinding crush 10-
11min obtains mixed-powder, continues mixed-powder and stirring liquid to be in mass ratio 3:1 mixing, and is 185-205/ in revolving speed
38-45min is stirred under conditions of min, dry discharging obtains modified mixed-powder；
It (2) is in mass ratio that 1:7 mixes immersion 9-10 days by attapulgite and deionized water, after removing silt and impurity,
The attapulgite after immersion is put into Muffle furnace again and is calcined, cooled to room temperature, and calcined attapulgite is ground
It is sieved with 100 mesh sieve after 12-15min, pack saves, and obtains pretreatment attapulgite；
It (3) is in mass ratio that 5:1:3 mixing is placed in by pretreatment attapulgite, neopelex and deionized water
Ultrasonic disperse in ultrasonic wave separating apparatus, ultrasonic disperse frequency are 31-32kHz, and the ultrasonic disperse time is 1-1.5h, obtain being modified recessed
Convex stick soil dispersion liquid；
(4) according to parts by weight, 33-36 parts of attapulgite modified dispersion liquids, 10-11 parts of modified mixed powders are weighed respectively
End, 7-8 parts of calcium carbonate and 21-23 parts of deionized water mixing are placed in blender, are in revolving speed
1.5-2h is stirred under conditions of 210-230r/min, then adds 3-4 parts of polyacrylate dispersions, 2-3 parts of peroxidating
Benzoyl continues to keep revolving speed that 16-18min is mixed, obtains mixed slurry, then mixed slurry is poured into a thickness of 3-
5mm, weight 4-6kg/m2 facing bricks die in, and temperature be 115-120 DEG C of solidification 35-42min, continue after solidification
Heat preservation heat treatment 1.5-3h, cooling discharging is to get attapulgite modified tapestry brick.
Step (2) calcination temperature is 360-410 DEG C, calcination time 1.5-2h.
Three, beneficial effect
The present invention is compared to the prior art, has the following beneficial effects:
For the present invention with attapulgite for natural mud powder, modified mixed-powder and calcium carbonate are aided with poly- third as promotor
Attapulgite modified tapestry brick, the leaching that attapulgite is passed through water first is prepared in olefin(e) acid ester lotion and benzoyl peroxide etc.
The pretreatment of bubble and high-temperature calcination sloughs the zeolite water, absorption water and the crystallization water of attapulgite, makes the needle bar shape group of attapulgite
It is loose porous, closed duct is activated, increases specific surface area and void content, while further reacting offer with surfactant
More active sites form aggregation porous structure, and gas is closed in countless small non-interconnected ducts, so that gas
Thermal coefficient is smaller, to improve the heat insulating ability of tapestry brick, stearic acid is recycled to be modified magnesium hydroxide and aluminium hydroxide jointly,
Promote hydroxide that there is good compatibility in system, decomposes after being heated due to hydroxide, be easy to absorb burning
Object surface heat, so that the large quantity of moisture for playing fire retardation, while releasing can be decomposed with the oxygen on dilute combustion object surface
The activating oxide of generation is attached to combustible surface, further prevents the progress of burning, hydroxide is in entire fire-retardant mistake
Cheng Zhong is not only generated without any harmful substance, and can absorb pernicious gas and smog caused by macromolecule burning, from
And stop burning quickly, while eliminating smog, molten drop is prevented, to improve the anti-flammability of tapestry brick, while these decompose life
At activating oxide be dispersed in the surface of tapestry brick, form effective anti-aging protective layer, hinder oxygen, ozone
Further decomposition of the equal substances to tapestry brick, the anti-aging property for being conducive to tapestry brick are improved, continue to add into system
Calcium carbonate, since calcium carbonate has splendid penetration, effectively the hole in filling and blocking system, improves the cause of system
Density, while calcium carbonate has good thermal stability and thermal insulation, has completely cut off the propagation of heat, plays good synergistic and makees
With further increasing the anti-flammability and heat insulating ability of tapestry brick, be with a wide range of applications.
