In order to make the better and inorganic materials bonding of adhesive mortar energy, above-mentioned coupling agent preferred silane coupling agent or titanate coupling agent.
In order to alleviate the weight of additive, keep good dispersiveness simultaneously again, above-mentioned anti-caking filler adopts following particle diameter and grating:
Particle diameter＜1 micron 8-23% weight ratio
Particle diameter＞50 micron 77-92% weight ratio
The preferred silicon ash of anti-caking filler of above-mentioned particle diameter＜1 micron, SiO2 that this silicon ash produces when being smelting ferrosilicon and industrial silicon and Si gas and the rapid oxidation of airborne oxygen and condensation and a kind of ultra-fine siliceous powder body material that forms.
The preferred water-ground limestone of anti-caking filler and/or the flyash of above-mentioned particle diameter＞50 micron.
The preferred toluene of above-mentioned solvent, dimethylbenzene or vinyl acetate.
The preferred hexanodioic acid propylene glycol of above-mentioned softening agent, dibutyl phthalate or dioctyl phthalate (DOP).
The additive of polystyrene thermal insulation plate adhesive mortar of the present invention, its prescription has following advantage:
1, adhesive mortar additive of the present invention, select for use the akin vinyl polymer of character and polystyrene thermal insulation plate as tacky resin, making itself and polystyrene board have good interface combines, be equipped with simultaneously a certain amount of not only can with the vinyl polymer reaction but also can with cement, the coupling agent of inorganic materials such as sand reaction, the adhesive mortar that contains this additive can finely be pasted with polystyrene board, can finely paste again with concrete wall surface, and by reacting the good stability of polymkeric substance in water that forms with coupling agent, the heat insulation system water tolerance that the polystyrene board of being pasted by this adhesive mortar constitutes is greatly improved.
2, by adding a certain amount of anti-caking filler, vinyl polymer and coupling agent can better be distributed in the mortar, guarantee that adhesive mortar has uniform cohesive force.
3, by adding certain amount of solvent or softening agent, increase the plasticity and the flowability of polymkeric substance, make additive easier, mixed with mortar more equably.
4, additive of the present invention, the cohesive strength height, addition is few, can reduce the cost of polystyrene board adhesive mortar greatly.
