Description
Technical field
The invention belongs to building material field, be specifically related to the building faced tackiness agent of a kind of returnable asphaltic base.
Background technology
The surface linings such as natural and artificial stone-like material are applied to the finishing of skin skirt etc. more and more widely, and its sticking Quality and weather resistance directly depend on the performance of used caking agent.In China, past uses sand-cement slurry or grout to carry out sticking construction to such surface lining always, because cement is not tamanori, add that densification, the water-intake rate of stone material are low, the grout prepared for base material with cement or the bonding cohesive force of sand-cement slurry to stone material is low, poor durability, easily coming off for pasting outer dado Stone brick, causing unpredictable potential safety hazard.In addition, such binding agent belongs to disposable caking agent, can not reclaim and reuse, and can cause a large amount of building wastes, waste resource, contaminate environment.Paving
At present, the common practice be in grout or sand-cement slurry, add doses high molecular polymer to improve grout or the bonding strength between sand-cement slurry and basic unit's stone material, it belongs to a kind of cement based adhesive of polymer modification.
The cement-based adhesive that CN101050341A discloses and is a kind ofly applicable to marble tile, stone material that grouan isodensity is large coheres.Adopt the compositions such as cement, sand, calcium carbonate, organic binder, thickening material.Be with cement and organic binder for major gelled material, sand and calcium carbonate are the cement-based mortar cakingagent of the preparations such as main aggregate, and cohesive strength is high.Belong to disposable caking agent, can not Reusability be reclaimed.
CN1052131A discloses a kind of tackiness agent of the building and ornament materials Rapid pasting for the basic metope such as cement, stone material.Employing vinylformic acid, Vinyl Acetate Copolymer are material of main part, mix with amino oxygen base silane class coupling agent etc.The material of main part adopted does not belong to cement class mortar cakingagent, and cost is higher.
CN1318535C discloses a kind of for the superpower tackiness agent of Wall or floor tile paving, adopts cement, yellow sand, limestone powder to be raw material, adds the sand-cement slurry base modified adhesive that aluminium sulfate expanding agent, Mierocrystalline cellulose and polyvinyl acetate glue milk powder etc. mix.This cakingagent formula is that to belong to cement be the sand-cement slurry cakingagent that base material is prepared, and belongs to disposable caking agent, can not reclaim Reusability.
CN101950796B discloses a kind of asphalt sealing agent for lead-acid storage battery and preparation method thereof, pitch, SBS, tackifying resin and silicon oxide is adopted to be base-material, with the sublimed sulphur of 0.1 ~ 0.5 part, the blended obtained asphalt sealing agent for lead-acid storage battery of halogenated flame retardant of 0.01 ~ 0.1 part.The a small amount of halogenated flame retardant added, cannot play its fire retardation, and in addition, due to environmental issue, many countries have forbidden or suspended using halogenated flame retardant.The sublimed sulphur added and SBS crosslinking reaction degree are too violent, and careless slightly the excessive of SBS that cause is cross-linked, and causes gelatin phenomenon.
