Abstract
The invention discloses a kind of gypsum based self-leveling mortar, the invention is mixed by components such as gypsum, flyash, coarse whiting, redispersable latex powder, water-loss reducer, defoamer, anti-settling agent, water reducer, thin river sands.From gypsum, flyash, as binder materials, the early strength after mortar hardening can be effectively ensured in the gypsum based self-leveling mortar of the present invention, and avoids the later stage the problem of shrink, and more environmentally friendly.Appropriate each analog assistant is added in formula, gravity flowing levelling mortar application property can be effectively ensured, and mortar combination property.
Description
Technical field
The present invention relates to building material field, and in particular to a kind of gypsum based self-leveling mortar.
Background technology
Gypsum based self-leveling mortar, is meticulous in factory by gypsum material, extraordinary aggregate and various architectural chemistry additives
A kind of dry powder and mortar dedicated for floor leveling of prepared by configuring, be well mixed.Self-leveling gypsum is used as replacement cement, energy
The staple product of China's carbon emission is reduced, current government has put into effect " the gypsum dry powder and mortar " of policy popularization, with energy-saving and emission-reduction
Social benefit and economic benefit.Following 10 years, Self-leveling gypsum China building materials market will obtain develop rapidly the phase.
The content of the invention
Present invention aims at there is provided a kind of gypsum based self-leveling mortar, the technical solution adopted by the present invention is as follows：
A kind of gypsum based self-leveling mortar, is configured to by following component by certain weight ratio：
30-50 parts of gypsum
4-6 parts of flyash
20-30 parts of coarse whiting
1-4 parts of redispersable latex powder
0.2-0.4 parts of water-loss reducer
0.3-0.5 parts of defoamer
0.1-0.5 parts of anti-settling agent
0.1-0.8 parts of water reducer
Thin 20-40 parts of river sand.
One of preferably, described water-loss reducer is by cellulose ether, starch ether, guar gum mixing composition.
One of preferably, described defoamer is organosilicon Series powder defoamer.
One of preferably, described anti-settling agent is oleic series anti-settling agent.
One of preferably, described water reducer is according to weight ratio by poly carboxylic acid series water reducer and calcium gluconae
For 5:1 mixing composition.
The present invention is relative to the beneficial effect of prior art：The gypsum based self-leveling mortar of the present invention selects gypsum, powder
The early strength after mortar hardening can be effectively ensured as binder materials in coal ash, and avoids the later stage the problem of shrink, and
It is more environmentally friendly.Appropriate each analog assistant is added in formula, gravity flowing levelling mortar application property can be effectively ensured, and mortar is comprehensive
Energy.
