Description
Technical field
The invention discloses a kind of cement-base waterproof coatings for building, belong to building material technical field.
Background technique
In recent years, with the raising and accumulation of water-based waterproofing paint properties of product, application experience, product annual growth is always
Keep ascendant trend.Although solvent borne polyurethane water-repellent paint has excellent comprehensive performance, reach level-one waterproof effect；But because
More and more limitations have been received containing harmful substances, application ranges such as anthracene, naphthalene, phenol, organic solvents in product form.And
Water base building water-proof paint is using water as carrier, safety and environmental protection, adapts to the waterproofing work of a variety of profiled-cross-section buildings base.Work as peace
Entirely, when environmental protection becomes human survival and develops primary need, the development of modern industry must be as basic principle.Water base waterproof applies
Expect a large amount of organic solvent in water consumption substitution solvent-type waterproofing paint, meets green low-carbon environment-friendly requirement, with product technology
Horizontal continuous improvement, will provide more solid guarantee for construction waterproofing engineering.Water base building water-proof paint water-proof mechanism has painting
Two kinds of film waterproof and hydrophobic waterproof.After coating application, with the volatilization of dampening, latex particle mutual extrusion condenses into fine and close painting
Film.It is this that the method that hydrone permeates or water penetrates is stopped to be known as coating waterproofing using film.Although made of fusion condensation
Macromolecular coating is intermolecular to have certain gap, but hydrone is usually existed by hydrogen bond action with state of associating, after association
Hydrone be difficult to through film.Aqueous-based polymers molecular structure carries hydrophilic radical, and the polymer of immersion applies for a long time
Film can be slowly swollen, and influence waterproof effect；So individually water base film can not block water completely.In order to improve polymer
Hydrophobicity usually introduces hydrophobic grouping the molecular structure of polymer, enhances the hydrophobicity of polymer itself, makes hydrone and applies
Film is incompatible, prevents hydrone from permeating.This method for stopping water to penetrate using hydrophobic grouping is known as hydrophobic waterproof.Building because
It is had been reported that when the cracking phenomena that the temperature difference, settlement of foundation, structure design, construction quality influences and generate, the leak of new and old building object,
Seepage problem has been one of main Quality of building trade.Cracking, water-based coating self-defect, consumer in face of substrate
The increasingly raising of decoration demand, the following water-repellent paint are wideling popularize development promotion coating water permeability resistance, tensile strength, anti-folding by force
It spends, the change functionality direction of tensile splitting strength is developed.
And there is also what waterproof performance and mechanical property can not further increase to ask for traditional architecture cement-base waterproof coating
Topic.Therefore, the shortcomings that how improving traditional architecture cement-base waterproof coating is it to obtain the promotion of more high combination property
It promotes and is applied to broader field, meet industrial production demand urgent problem to be solved.
Summary of the invention
The present invention solves the technical problem of: it is directed to traditional architecture cement-base waterproof coating waterproof performance and mechanics
The problem of performance can not further increase provides a kind of cement-base waterproof coating for building.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
A kind of cement-base waterproof coating for building, is made of the raw material of following parts by weight:
30~40 parts of cement
20~30 parts of styrene-acrylic emulsion

3~5 parts of surfactant
20~30 parts of modified filler
5~8 parts of black liquid
3~5 parts of water-reducing agent
Modified 5~8 parts of hollow carbon fiber
20~30 parts of water
The preparation process of the cement-base waterproof coating for building are as follows: each raw material is weighed by raw material composition, by cement, phenylpropyl alcohol cream
Liquid, greasy filth, surfactant, modified filler, black liquid, water-reducing agent, modified hollow carbon fiber and water, be stirred to get
Cement-base waterproof coating for building.
The cement is portland cement, any one in chloric acid salt cement or sulfate cement.
The styrene-acrylic emulsion solid content is 40~50%.
The surfactant is neopelex, any in lauryl sodium sulfate or glycerin monostearate
It is a kind of.
The preparation process of the modified filler are as follows: according to parts by weight, successively take 60~80 parts of activation chitosan liquid, 40~
50 parts of gelatin solutions, 10~20 parts of glutaraldehyde solutions, 10~20 parts of hydrochloric acid and 10~20 parts of graphene oxides will activate chitosan liquid
It is stirred with gelatin solution, and sequentially adds hydrochloric acid, glutaraldehyde solution and graphene oxide, after being stirred, filtering, stripping and slicing,
Washing, vacuum drying, obtains modified filler.
The water-reducing agent is sodium lignin sulfonate, in TH-928 poly carboxylic acid series water reducer or YZ-1 naphthalene series high-efficiency water-reducing agent
Any one.
The preparation process of the modified hollow carbon fiber are as follows: according to parts by weight, by 20~30 parts of hollow carbon fibers, 2~3
Part biogas slurry, 2~3 parts of glucose solutions, 30~40 parts of water mixed fermentations are then added dropwise 0.1~0.2 times of hollow carbon fiber quality
Iron nitrate solution is stirred, and is filtered, dry, and nitrogen charging high-temperature process obtains modified hollow carbon fiber.
The beneficial effects of the present invention are:
The present invention is by addition modified filler, in use, firstly, containing the gel knot sensitive to pH in modified filler
Structure, after being added in product, when near isoelectric points of proteins, gel can be with ring when deviateing isoelectric point in contraction state
The change of the pH in border and expand or shrink, with the progress of cement hydration process, the pH in system is begun to ramp up, and works as contact
When alkaline matter, pH rises around gel, and carboxylic ions are mutually exclusive with negative electrical charge of the same race, generates swelling stress, effectively supports
The swelling stress that the cement that disappeared generates early period in aquation, is avoided system and is cracked due to swelling stress, so that system
Mechanical property gets a promotion, meanwhile, swelling stress improves the consistency of system, to be promoted but also system is compacted
The waterproof performance of system, secondly, the pH of system constantly rises with the progress of cement hydration process, in the solid process of cement
In, basic component enables to the gelatin hydrolysis in modified filler, so that the graphene oxide in modified filler is released, body
Basic component in system makes the carboxylic ions on graphene oxide layer structure edge, since like charges are mutually exclusive,
Repel so that being formed inside system, is effectively offset the solid shrinkage stress generated in the process of cement, avoids system due to swollen
Swollen stress and crack so that the mechanical property of system is further promoted, meanwhile, but also system obtains further
Compacting, to further improve the waterproof performance of system.
