Described a kind of thermal insulation mortar foaming agent also comprises: polyoxyethylenated alcohol sodium sulfate: 5~10 parts, rosin: 10~15 parts, Ninol: 0.01~2 part, silicon ash: 1~10 part, silicone resin: 0.02~3 part, water reducer: 0.1~3 part, caustic soda: 1~5 part, hydrochloric acid: 0.1~2 part.
A kind of method for preparing above-mentioned a kind of thermal insulation mortar foaming agent is prepared raw material by above-mentioned weight part proportioning, and prepares by following step:
The first step: glue class and animal proteinum are prepared into powdery and mixing, place in the heating container, under 70~80 ℃ of temperature condition, water-bath 5~7 hours is with products therefrom cooling, filtration;
Second step: sodium lauryl sulphate, X 2073, α-sodium olefin sulfonate and polyethers emulsion is all soluble in water, be heated to 100 ℃ and be incubated 2.5 hours then;
The 3rd step: above two kinds of mixtures are put into heating container mix, surplus water is added, stirred this secondary mixture 2 hours;
The 4th step: required deal rubber powder, HPMC are added in the above-mentioned secondary mixture, and stirred 1~2 hour, what draw promptly is this whipping agent.
The method of the above-mentioned a kind of thermal insulation mortar foaming agent of another kind of preparation is prepared raw material by above-mentioned weight part proportioning, and presses following step preparation:
The first step: glue class, rosin, animal proteinum and caustic soda are prepared into powdery and mix, then add hydrochloric acid and place in the heating container, under 70~80 ℃ of temperature condition, water-bath 5~7 hours is with the products therefrom cooling, filter;
Second step: sodium lauryl sulphate, X 2073, polyoxyethylenated alcohol sodium sulfate, α-sodium olefin sulfonate, Ninol, silicon ash, silicone resin, polyethers emulsion and water reducer is all soluble in water, be heated to 100 ℃ and be incubated 2.5 hours then;
The 3rd step: above two kinds of mixtures are put into heating container mix, surplus water is added, stirred this secondary mixture 2 hours;
The 4th step: required deal rubber powder, HPMC are added in the above-mentioned secondary mixture, and stirred 1~2 hour, what draw promptly is this whipping agent.
The present invention compares the beneficial effect that has with prior art:
1, adopted organic and inorganic technologies composite foamed, the foam of generation is small and amount is big, has improved the effect of foaming greatly.
2, through adding animal proteinoid material, glue class material, chemicaladditives etc., the foam of generation is had " skeleton ", certain intensity is promptly arranged, at room temperature, this foam can be preserved more than 24 hours.
3, the foam that sends of this whipping agent can be on the foam wall after the foaming film forming, each foam is independently sealed, different foam amounts with can reduce thermal conductivity 0.02~0.04w/mk after mortar mixes, improve heat-insulating property.
4, with thermal insulation mortar mechanically spraying foaming technique seamless combination, can make the bubble amount reach optimization, the foamed heat insulating mortar of ejection is even, high-strength, thermal conductivity is low, and reduces cost.
5, this whipping agent preparation method is simple, and cost is low, and is higher than traditional whipping agent foaming efficient, adds to reach the requirement of bubble amount on a small quantity.
