Abstract
The invention discloses mono-component polymer-cement waterproof mortar which comprises Portland cement, redispersible latex powder, cellulose ether, water reducers, defoamers, quartz sand and quartz powder. The mono-component polymer-cement waterproof mortar adopts a mono powder packaging form and is stirred uniformly with water in different quantities when used so as to obtain the mortar different in thickness, thereby being applicable to construction modes of blade coating with a scraper, brush coating with a brush and roll coating with a roller and applicable to water proofing of bathrooms, kitchens, balconies and the like in the field of home decoration water proofing. The waterproof mortar has excellent waterproof performance, can be constructed on moist bases and is high in cementing bond with the bases, resistant to water, heat and alkali and environment-friendly without volatilization of toxic and harmful gases.
Description
Technical field
The present invention relates to a kind of single polymer cement water-proof slurry, belong to building material field.
Background technology
In recent years, in the waterproofing work in house ornamentation field, polymer-modified cement class waterproof paint is with its excellent water resistance, good environmental protection characteristic, and application percentage rises year by year in waterproofing work.Such waterproofing slurry is generally water paste, can directly on wet base, construct, than the requirement of oiliness waterproof paints such as urethane, pitch to basic unit.On the other hand, waterproof paints such as urethane, pitch need carry out interface processing, play the work of steps such as resist after waterproof construction, before the furring brick operation, and engineering cost is increased.The polymer cement waterproof slurry then can directly carry out patch block to be handled, and has certain advantage in this respect.
Generally adopt the packaged form of liquid material and powder two-pack at present in the polymer cement waterproof paint, two kinds of components are mixed stirring during use, carry out the construction of blade coating, brushing or roller coat again; But the packing of two-pack often makes the transportation of product, storage cost increase, and can't realize remaining the repeatedly utilization of powder, and two-pack is because the difference of physico-chemical property has also been brought higher requirement to storage condition simultaneously.
In addition; The behavior owing to often use inferior materials and turn out substandard goods in the house ornamentation waterproof construction process at present; Some contractor in order to save material in the polymer cement waterproof material the excessive water of admixture; Seeking to brush bigger area, this class behavior brings the hidden danger of seepage with each item performance of havoc water-proof material weather resistance particularly to buildings.
Summary of the invention
In order to overcome problem and the defective that present waterproofing slurry exists; The invention provides a kind of single polymer cement water-proof slurry with good water resistance, this waterproofing slurry coating self is not easy to crack, can be in moist basal plane construction, strong, water-fast, heat-resisting, alkaline-resisting with basic unit's cohesive force; Environmental protection, the volatilization of no hazardous and noxious substances, and adopt the packaged form of single powder, and be convenient to transportation, store, convenient, practical.Further, the color of sclerosis waterproof layer was convenient to the supervision of the department of managing when described single polymer cement water-proof slurry can be printed on maximum amount of water, guaranteed construction quality.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of single polymer cement water-proof slurry is characterized in that being made up of silicate cement, redispersable latex powder, ether of cellulose, water reducer, skimmer, silica sand, silica powder.
Wherein, said each component is made up of following ratio, by weight percentage:
In the present invention, used silicate cement does not receive special restriction, and any existing ordinary Portland cement all can be used for technical scheme of the present invention; Used silica sand, silica powder can be selected as required, and preferred, said silica sand is the 80-120 order; Said silica powder is 200 orders.
In the above, redispersable latex powder is a kind of water-soluble redispersible powder, is the multipolymer of ethylene/vinyl acetate, vinyl acetate between to for plastic/tertiary monocarboxylic acid ethylene copolymer, acrylic acid multipolymer etc., with Z 150PH as protective colloid.What the present invention was used can be any known available redispersable latex powder, includes but not limited to vinyl acetate and ethylene copolymer rubber powder (Vac/E), ethene and vinylchlorid and month silicic acid vinyl acetate terpolymer rubber powder (E/Vc/VL), vinyl acetate and ethene and higher fatty acid vinyl acetate terpolymer rubber powder (Vac/E/VeoVa), vinyl acetate and higher fatty acid vinyl acetate copolymerization rubber powder (Vac/VeoVa), propenoate and styrene copolymerized rubber powder (A/S), vinyl acetate and propenoate and higher fatty acid vinyl acetate terpolymer rubber powder (Vac/A/VeoVa), vinyl acetate homopolymerization rubber powder (PVac), vinylbenzene and butadiene copolymer rubber powder (SBR) etc.
In the above, water reducer as is known to the person skilled in the art, is a kind of under concrete workability and cement consumption permanence condition, can reduce the mixing water amount, improve concrete strength; Or under workability and intensity permanence condition, practice thrift the admixture of cement consumption.The present invention does not limit the type of used water reducer, and known in the art arbitrarily, available water reducer all can be used for the present invention, includes but not limited to lignosulfonic acid sodium salt water reducer; Naphthalene series high-efficiency water-reducing agent; Aliphatic high-efficiency water reducing agent, amino high high efficiency water reducing agent, high-efficiency water-reducing agent of poly-carboxylic acid etc.; Preferred used is high-efficiency water-reducing agent of poly-carboxylic acid, all can purchase from market.
In the above; Skimmer; Put down in writing like the chemical industry dictionary; Be used for eliminating or preventing harmful foam that industrial process produces, include but not limited to natural fats and oils, higher alcohols, organo-siloxane, polyethers, silicon and ether grafting, contain amine, imines and amides, polyether-modified silicon etc., preferably YSR 3286.
Further, on the basis of such scheme, also can add wood fibre, the smoothness and the application property of waterproofing slurry when constructing to improve, the content of wherein said wood fibre is 0.05%-0.2%, by weight percentage.
Further, on the basis of such scheme, also can add talcum powder and be used to improve water resistance, said talcous ratio is 4%-6%, by weight percentage; Preferably, said talcum powder is 600 orders.
Further, on the basis of such scheme, also can add pigment, thereby realize the construction quality purpose of control waterproofing slurry, the ratio of said pigment is 0.5%, by weight percentage.Through adding described pigment; If make that amount of water was too much when single polymer cement water-proof slurry of the present invention stirred in use; Can influence the performance of waterproofing slurry; The color of the water resistant solution bed of material of hardening simultaneously shoals, and has realized the supervision to waterproofing quality, thereby has prevented using inferior materials and turning out substandard goods in the construction process.
Accordingly; The invention discloses the method for use of said single polymer cement water-proof slurry; In use single polymer cement water-proof slurry dry powder is added entry and use, the maximum amount of water of wherein said single polymer cement water-proof slurry is no more than 33% of dry powder weight.
In use, mainly comprise following several kinds of service conditions, the consumption of corresponding water is described below respectively:
Amount of water suitable when adopting the scraper plate knife-coat application is the 20%-25% of dry powder weight;
