Description
Technical field
The invention discloses a kind of crack resistences to sterilize tile grout, belongs to building material technical field.
Background technique
Ceramic tile is widely used in building field because it has many advantages, such as beautiful and generous, hard solid.Tile grout conduct
The mating pointing of tile paste increases along with ceramic tile usable floor area and is increased.As people's living standard and understanding improve,
Tile grout also develops to the polymer-modified cement-based gap filler of current mainstream from initial white cement.
Gap filler is more a kind of chemicals in building trade, and gap filler is mainly used for facing tile facing body
System, quality directly affect outer wall decorative effect.Usually it is strong with adhesion, contraction is small, color pull-out capacity is strong, has anticracking
The flexibility of line, decoration texture is good, and compressive resistance is wear-resistant, antimycotic feature.
Currently, gap filler used in tile decorative surface is to be wrapped using ordinary cement, building fine sand, inorganic pigment through mixing mostly
Dress, the packing material to be tempered when using as ceramic tile seam, using the time that do not grown after the completion of the construction of this tile grout
It through wind, solarization, drenches with rain, under the influence of the factor of natural environment of freeze thawing etc., the ceramic tile metope whiting that large area will occur is returned
Alkali, contraction fissure, mildew, even ceramic tile fall off and other issues and security risk.This field once occurred using epoxy resin,
Curing agent and the technical solution of filler mixing filling attempt thoroughly to solve problem above.But epoxy resin used in such scheme and
Curing agent is all no-solvent type, is easy to pollution ceramic tile surface in use, and cleaning is extremely difficult, is easy to leave a trace,
Meanwhile construction appliance also extremely difficult cleaning, cause construction inconvenient.There is also bactericidal properties for tile grout traditional at present not
It is good, the problem of anti-cracking performance can not further increase, therefore also need to study it.
Summary of the invention
The present invention solves the technical problem of: bad, the anti-cracking performance for traditional tile grout bactericidal property
The problem of can not further increasing, provides a kind of crack resistence sterilization tile grout.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
A kind of crack resistence sterilization tile grout, is made of the raw material of following parts by weight: 55~75 parts of cement, and 20~30 parts
Dicalcium powder, 12~18 parts of re-dispersible glue powders, 2~6 parts of dispersing agents, the crack resistence sterilize tile grout further include: cement
The additive and 0.1~0.2 times of cement quality of graphene oxide that 0.2~0.3 times of quality；
The additive the preparation method comprises the following steps:
Montmorillonite is mixed with water 1:50~1:55 in mass ratio, and 0.3~0.4 times of montmorillonite quality of cetyl three is added
Methyl bromide ammonium after being stirred to react, is filtered, is washed, dry, obtains modified montmorillonoid；In mass ratio by chitosan and acetum
1:20~1:30 mixing after being stirred, stands, chitosan solution is obtained, by chitosan solution and salicylide 10:1 in mass ratio
~12:1 mixing after being stirred to react, stands, is centrifuged, washs, dry, obtains modification of chitosan；Modified montmorillonoid and water are pressed into quality
It is mixed than 1:30~1:40, modified montmorillonoid dispersion liquid is obtained, by modification of chitosan and acetum 1:10~1:20 in mass ratio
Mixing, and adjust pH has precipitating wadding body to occur into the mixture of modification of chitosan and acetum, obtains modification of chitosan dispersion
Liquid mixes modification of chitosan dispersion liquid with modified montmorillonoid dispersion liquid 1:2~1:3 in mass ratio, after being stirred to react, filtering,
Washing to cleaning solution is neutrality, dry, obtains additive blank, by additive blank and silver nitrate solution 1:8~1 in mass ratio:
12 mixing, stand, and filter, dry, obtain additive.
The cement is any one in common 52.5 grades of portland cements or common 42.5 grades of portland cements.
The dicalcium powder is the dicalcium powder that mesh number is 320 mesh.
The redispersable latex powder is vinyl acetate-ethylene copolymer.
The dispersing agent is dispersing agent NNO, any one in Dispersant MF or dispersing agent C NF.
The montmorillonite is the montmorillonite that mesh number is 80 mesh.
The chitosan is the chitosan of deacetylation 70~85%.
The beneficial effects of the present invention are:
Additive and graphene oxide is added when preparing crack resistence sterilization tile grout in the present invention, firstly, containing in additive
There is the montmorillonite of lamellar structure, and in montmorillonite by modified, cetyl trimethylammonium bromide enters the lamella of montmorillonite
In structure, so that the hydrophobicity of montmorillonite be made to improve, and then after being added in product, the waterproofness of product can be made to be turned up, it is antifouling
Property improve, also, due to the cetyl trimethylammonium bromide of addition have certain bactericidal property, so as to make killing for product
Bacterium performance improves, secondly, being additionally added the modified chitosan of salicylide in additive, on the one hand, the addition of chitosan can be further
The bactericidal property of product is improved, on the other hand, chitosan is modified in salicylide, and enters in the lamellar structure of montmorillonite, from
And the absorption property of additive can be made to improve, after being mixed with silver nitrate, silver ion can be fixed in additive, so as to make
The bactericidal property of product further increases, furthermore, the graphene oxide of addition can be ionizable in cement hydration process and in oxygen
Graphite alkene surface generates negative electrical charge, so as to form Electrostatic Absorption between chitosan, and forms three-dimensional network in interiors of products,
And since the lamellar structure of montmorillonite is present in product, and then the anti-cracking performance of product can be made to improve.
