Description
Technical field
The invention belongs to building material technical field, more specifically relate to a kind of PTB waterproof ventilated type aerated concrete block interfacial agents and using method thereof.
Background technology
Air-entrained concrete building block interfacial agents in the market has problems to some extent, causes air-entrained concrete building block wall crazing and hollowing, and this engineering that has limited air-entrained concrete building block is to a certain extent used.At cracking, the hollowing phenomenon of air-entrained concrete building block body of wall, domestic and international many scientific and technical personnel have studied many method and supplementary materials of improving air-entrained concrete building block body of wall interface according to the air-entrained concrete building block material behavior, have obtained certain progress.At present less at the research of air-entrained concrete building block interfacial agents, especially having simultaneously in research does not almost have aspect the novel interfacial agent of cohesiveness, water-repellancy, water-retentivity and weathering resistance ventilation property.So press for a kind of novel air-entrained concrete building block interfacial agents, solve the difficult problem of air-entrained concrete building block industry, bring good economic and social benefit.
Summary of the invention
The purpose of this invention is to provide a kind of PTB waterproof ventilated type aerated concrete block interfacial agents, have cohesiveness, water-retentivity, water-repellancy and weathering resistance ventilation property preferably simultaneously.The water-repellancy of this interfacial agents guarantees that air-entrained concrete building block can not be in the moisture expansion and drying shrinkage state all the time, the air-entrained concrete building block body of wall is used from constructing to be in the unidirectional wet process of separating always, and body of wall is more and more stable; The water-retentivity of interfacial agents guarantees that the moisture in the interfacial agents can very fast evaporation or add the gas concrete segment and siphon away, thereby causes the interfacial agents efflorescence; Its weathering resistance ventilation property guarantees that the plastering mortar of air-entrained concrete building block body of wall the hollowing phenomenon can not occur under the sun tans by the sun.This interfacial agents can solve the difficult problem that air-entrained concrete building block is used medium-term and long-term puzzlement people, is fit to large-scale promotion application, has remarkable economic efficiency.
A kind of PTB waterproof ventilated type aerated concrete block interfacial agents of the present invention is: be made up of PTB aqueous solutions of polymers and the special-purpose powder of PTB; The weight ratio of the special-purpose powder of PTB aqueous solutions of polymers and PTB is: (0.1～0.3): 1; The weight ratio of the special-purpose powder of the PTB aqueous solution and PTB is 0.1～0.3: 1; The PTB aqueous solutions of polymers is: with PTB emulsion and water 1:1～39 by volume, mix; The composition of the special-purpose powder of PTB comprises at least: ordinary Portland cement, fine sand, flyash, water reducer or ether of cellulose.
The using method of PTB waterproof ventilated type aerated concrete block interfacial agents of the present invention: the using method process comprises: flat cleaning is mended by basic unit, water spray is moistening; The preparation of PTB waterproof ventilated type aerated concrete block interfacial agents; The construction of PTB waterproof ventilated type aerated concrete block interfacial agents; Maintenance.
Remarkable advantage of the present invention is: the present invention has stronger cohesiveness, bonds firmly with basic unit, has better waterproof, reduces the possibility that extraneous moisture carries out building block; Have water-retentivity preferably, thereby guarantee that the moisture content in the mortar can be by the too fast absorption of air-entrained concrete building block, the forfeiture cohesive strength; Have the certain deformation ability, can produce corresponding deformation with the moisture expansion and drying shrinkage of air-entrained concrete building block; 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 intensity fast development of air-entrained concrete building block interfacial agents.The PTB emulsion is a kind of organic binder bond, carrying out along with hydration process, the dehydration of PTB emulsion forms polymeric film, around the cavity that this film continuous distribution is produced when cement solidification, 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, can improve its water-retentivity greatly because added ether of cellulose again.PTB waterproof ventilated type aerated concrete block interfacial agents of the present invention can overcome the shortcoming of existing air-entrained concrete building block interfacial agents, has remarkable economical and social benefit.
The advantage of PTB waterproof ventilated type aerated concrete block interfacial agents of the present invention:
(1) has stronger cohesiveness: bond firmly with basic unit, can not cause coming off and hollowing of float coat.
(2) have better waterproof: preventing that extraneous water is penetrated in the air-entrained concrete building block goes, and causes gas concrete to be in the moisture expansion and drying shrinkage state for a long time.
(3) has water-retentivity preferably: guarantee that the moisture in the interfacial agents can not caused the interfacial agents efflorescence by the too fast absorption of air-entrained concrete building block.
(4) has the better weather ventilation property: can allow the interior moisture of air-entrained concrete building block distribute gradually, guarantee that the plastering mortar of air-entrained concrete building block body of wall the hollowing phenomenon can not occur under the sun tans by the sun.
