The waterproof ventilating type old wall ceramic tile retreading interface agent consists of copolymer solution, 42.5 ordinary portland cement and fine sand, and a small amount of fly ash, water reducing agent, cellulose ether and PVA are added at the same time; a using method of the interface agent comprises the following steps of: (1) cleaning a base layer: cleaning floating dust, residues, oil stains and the like on a base surface of the well, preferably by using oxalic acid; (2) preparing the interface agent: mixing and preparing the interface agent according to the formula; (3) constructing the interface agent: constructing the prepared interface agent by using a spray gun or a roller, wherein the thickness of the constructed interface agent is 0.8 to 1.2 mm, and the construction is not carried out in rainy days; and (4) maintaining: after the completion of the construction, maintaining the interface agent for 12 to 24 hours and performing plastering construction.
Description
Technical field
The invention belongs to building material technical field, more specifically relate to a kind of waterproof ventilating type old wall ceramic tile retreading interface agent and using method thereof.
Background technology
Be built in 70, the house of the eighties had a strong impact on the outward appearance of buildings through the Exposure to Sunlight of exposing to wind and rain, even phenomenons such as external wall seepage, ceramic tile hollowing come off occur, and must or rebuild through maintenance, reconstruction will be wasted the lot of manpower and material resources financial resources.So the best way is to carry out old wall renovation, reinvents the external wall waterproof system, and can reach effect attractive in appearance.If old wall ceramic tile is all destroyed sticking brick again, will produce a large amount of dust and noise, resident living and work solve this difficult problem so press for a kind of waterproof ventilating type old wall ceramic tile retreading interface agent at present near the influence.
Summary of the invention
The purpose of this invention is to provide a kind of waterproof ventilating type old wall ceramic tile retreading interface agent, this interfacial agents can solve at present, and old building construction exterior wall seriously seeps water, the ceramic tile hollowing comes off problem, have better cohesiveness, water-repellancy and ventilation property simultaneously, can carry out the old wall renovation of ceramic tile face, and can reinvent the external wall waterproof system, be fit to large-scale promotion application, have remarkable economic efficiency and social benefit.
The technical solution adopted in the present invention is: a kind of waterproof ventilating type old wall ceramic tile retreading interface agent, it is characterized in that: described waterproof ventilating type old wall ceramic tile retreading interface agent is mainly by copolymer solution, 42.5 ordinary Portland cement and fine sand are formed, add a spot of flyash simultaneously, water reducer, ether of cellulose and PVA; Described copolymer solution by ternary copolymer emulsion and water by volume 1:1-5 mix, account for the 15-20% of gross weight; Calculate by mass percentage, 42.5 ordinary Portland cements that added account for the 27-40% of gross weight, fine sand accounts for the 30-55% of gross weight, flyash accounts for the 0-18% of gross weight, water reducer content is the 0-0.4% of cement consumption, ether of cellulose content is the 0.2-0.4% of cement consumption, and PVA content accounts for the 0-1.45% of gross weight, mixes.The particle diameter of its medium sand should be at the 40-140 order, and flyash adopts
Level, water reducer adopts high efficiency water reducing agent, and ether of cellulose adopts methyl cellulose ether, and PVA adopts polyvinyl alcohol, and above-mentioned materials is mixed, and has both got the waterproof ventilating type old wall ceramic tile retreading interface agent.The using method of this interfacial agents is: base cleaning (cleaning of ceramic tile face) → interfacial agents preparation → interfacial agents construction → maintenance.More concrete steps are: (1) base cleaning: the floating dust on the body of wall basal plane, residue, oil stain etc. are cleaned out, preferably adopted oxalic acid to clean; (2) interfacial agents preparation: according to described prescription mixed preparing; (3) interfacial agents construction: the interfacial agents for preparing is adopted spray gun or roller construction, and thickness is avoided the rainy day construction at 0.8-1.2mm; (4) maintenance: after construction finishes, maintenance 12-24h, the construction of just wiping one's face then.
Remarkable advantage of the present invention is: this interfacial agents has air permeability and good, water-repellancy and cohesiveness, good with basic unit old wall ceramic tile face bonding, can improve the smooth interface of old wall ceramic tile, make the roughening of ceramic tile face, can carry out the renovation of old wall under the old ceramic tile situation need not to knock out, shorten the construction period.And the ordinary Portland cement that uses in the raw material of the present invention is a kind of mineral binder bond, and it and water generation hydration reaction generate the C-S-H gel, make the cohesive strength fast development of waterproof ventilating type old wall ceramic tile retreading interface agent.Ternary copolymer emulsion is a kind of organic binder bond, carrying out along with hydration process, the ternary copolymer emulsion dehydration forms polymeric film, around the cavity that this film continuous distribution is produced when hydrated cementitious, they is bonded to a firm integral body firmly, and across the microscopic checks in the sand-cement slurry hardenite, the connection of shuttling back and forth becomes whippy " hinge " structure when stressed, both disperseed stress concentration, increase resistance capacity to deformation again, improved the cohesive strength of interfacial agents.Terpolymer breast thing water-swellable, dehydration is shunk, can the refinement pore texture, the water vapour molecule of tiny diameter can be appeared from this hole, and larger-diameter extraneous moisture can't infiltrate from this hole.This makes the body of wall after the renovation have good water-repellancy on the one hand, reaches the purpose of reinventing old wall waterproof system; Also improved the ventilation property of old wall ceramic tile face on the other hand, avoided renovating back wall hollowing rimose purpose thereby reach.
