Description
Technical field
The invention belongs to building material technical field, relate to a kind of composition, the penetration crystallization type water proofing paint that particularly a kind of buildings waterproof is used.
Background technology
Concrete is a kind of heterogeneous body, porous, and has microfissue structure, shaggy hypertonicity material.It can pass through the kapillary planar water, and this process usually is accompanied by the absorption to objectionable impurities.With regard to water, water can cause material generation frost and thaw, if the erosion that divided by water in air will make base material suffer the heavily stressed of alternation of wetting and drying, causes surface cracking, and fissured generation and development will cause objectionable impurities to be invaded; The material that is dissolved in the water, particularly chlorion can destroy the passivation layer of rebar surface, cause catastrophic corrosion; Water can be carried pollutent and dust secretly, makes structures stained; Water also can make salinity by the internal migration of material to outside, thereby make structures surface weathering and produce salt efflorescence.The various degradation mechanism of comprehensive concrete structure as can be known, nearly all chemistry and physical process that influences concrete structure durability all relates to two principal elements, i.e. water and its migration in concrete pore and crack.Therefore, take surface waterproofing to prevent water intrusion in the external environment, to improving concrete durability, guaranteeing that the concrete appearance cleaning is very important to concrete structure.
Water-proof material is numerous at present, mainly is divided into two classes according to the effect waterproof, i.e. film-forming type (physics mode) coating and osmosis type (chemical mode) coating.Film-forming type is to utilize protective coating self film forming to stop that corrosive medium enters concrete, and the concrete protection effect and the film forming character of shape of this coating way are closely related, and the character quality of film directly influences the concrete durability quality.Osmosis type coating is meant that waterproof paint infiltrates inside concrete, generate new material with the hydrated cementitious product generation complex physico-chemical in the cement stone hole, this new material has stronger hydrophobic nature, can change the wetting angle of cement stone pore wall and water, and then effectively prevention is the corrosive medium intrusion of carrier with water.
Conventional waterproof coating such as pitch, Resins, epoxy, urethane, acrylic resin and ethenoid resin etc., by at concrete surface brushing certain thickness, can the oversite concrete surface, stop up concrete pore, thereby reach the purpose that stops extraneous moisture to be invaded.But because concrete surface is capped, hole is blocked, itself is airtight, when moisture is discharged internally, the water-proof coating on surface can be broken through, and causes the coating and the lost of life thereof.In addition, these conventional waterproof materials have the shortcoming that self is difficult to overcome, and can wear out in physical environment, fade and peel off as long-term exposure, and alkali resistance is poor, sticking power is little, self poor durability, inhale ash etc. easily.Use wider a kind of novel penetration crystallization type water proofing paint in recent years, it is strong to have self-healing ability, good penetrability, the cohesive strength height, advantages such as easy construction, such waterproof paint is a cement-base waterproof coating, mainly by cement, quartz sand and active chemistry are formed, wherein active chemistry has many kinds, organosilicon particulate for example, lipid acid, potassium permanganate, materials such as yellow soda ash, but most of in these materials have certain action of rust to mortar or steel bars in concrete, and a large amount of potassium metals have been introduced, sodium etc. will strengthen mortar or concrete alkali, cause the reduction of self inherent strength.
Summary of the invention
The object of the present invention is to provide a kind of penetration crystallization type water proofing paint, possess surface enhancing, anti-carbonization, anti-hazardous medium infiltration function simultaneously, and have characteristics such as easy construction, cost be low.
The applicant finds after deliberation: the major cause of concrete structure deterioration is the intrusion of water, also comprise simultaneously the objectionable impurities that is dissolved in the water, thereby cause the concrete surface cracking, cause the inside concrete damage, especially chlorion or carbonic acid gas are that carrier is invaded inside concrete with water, can cause inner reinforcing bar generation corrosion and concrete generation carbonization.
Based on above-mentioned research, the present invention is coated with thinking outward based on cement based penetration crystallization type water proofing paint, with cement as main film-forming components, and select suitable film coalescence aid, increase the toughness of cement based penetration crystallization type water proofing paint, concrete surface is strengthened, and effective blocking concrete capillary-size pore, surface and tiny crack, the intrusion of extraneous water and other hazardous mediums stoped; Introduce high osmotically active silicon additive and complexing agent simultaneously, be penetrated into inside concrete by carrier, physical-chemical reaction takes place in pore, generate water-fast complicated and confused shape xln, sealing inside concrete pore and microfracture, thereby the effectively shutoff intrusion of water that comes from the outside, play block water, waterproof effect.
