Abstract

The foaming agent adopts water, sodium carbonate, rosin, triethanol amine, sodium dodecyl sulfate and sepiolite powder as basic material. It has relatively high sodium carbonate and rosin content, has high stability, and can produce more foam, raise strength, mixability and moisture preservation of mortar, and replace whole lime material and partial cement material. Sepiolite powder makes the product become powder rather than liquid, and this facilitates the packing, storage and transportation. Its use is very convenient, needing no hot water for dissolution.

Description

Efficient mortar foaming agent and preparation method thereof

The present invention relates to for building build by laying bricks or stones, the whitewash mortar admixture.

The mortar additive that is adopted in the existing building industry (disclosed as Chinese patent CN1037132A and CN1075305A) mostly is the admixture of bleed formulation, this class mortar additive is to replace lime consumption in the mortar by increasing air content, reach the purpose of economical with materials, it must add the hot water dissolving in construction, the molten shape of furnishing, mix in the mortar again and stir, use inconvenient, the water retentivity of mortar of mixing out with this type of admixture can be relatively poor in addition, shipment distance is long slightly, after being vibrated slightly, the easy layering of mortar is not easy to the operation construction.Why produce this kind phenomenon, its major cause is that the foam degree of product is not enough, and promptly workability is bad, product is liquid, product itself is easily layering just, and improper use will influence the quality of mortar quality, causes the quality instability, bring many inconvenience for the operation construction, moreover existing mortar additive person is liquid product, and the Packing Fee height is fragile, and also be not easy to transportation, thereby necessary this improved.

The object of the invention is to provide a kind of stable performance, and foam degree height uses simply, and cost is low, can satisfy the workability of mortar, improves intensity, substitutes whole lime in the mixed mortar, efficient mortar foaming agent and the manufacture method thereof that also can save part cement.

The present invention influences the theory of its performance inadequately because of the foam degree according to existing mortar additive, adopt new prescription, be means to improve admixture foam degree emphatically, improve the content of rosin and soda ash greatly, its composition and prescription are to add the water modulation by soda ash, rosin, trolamine, sodium lauryl sulphate (K12) effective ingredient to form, between each active princlple behind the chemical reaction preparation, form aqueous goods, as sorbent material powder is made in the absorption of aqueous goods with sepiolite powder again, thereby effectively solved the problem of packing, accumulating inconvenience.The weight proportion of each component raw material of the present invention following (weighing 100 parts) based on water:

100 parts in water

30 parts～32 parts of soda ash

56 parts～60 parts of rosin

17 parts～19 parts of trolamines

5 parts～5.5 parts of sodium lauryl sulphate

790 parts～810 parts of sepiolite powders

Wherein soda ash, rosin, trolamine, sodium lauryl sulphate are effective ingredient, and sepiolite powder is the absorption material.

Blending process of the present invention is, start is stirred when at first 100 parts of water being heated to 100 ℃～110 ℃ in reactor, after adding the whole dissolvings of soda ash, slowly adding rosin continues to stir, all be dissolved into liquid, be cooled to 40 ℃ and add trolamine again, sodium lauryl sulphate mixes that to go out still in 20～30 minutes be work in-process.Sepiolite powder is poured into again, mixed with work in-process and stir by forced stirrer, sepiolite powder is all adsorbed work in-process, needing 40 minutes pressure to stir the back be the powdery finished product.

The present invention be a kind of be main surfactivity air entrapment agent by the sodium abietate that forms after soda ash and the rosin saponification, add sodium lauryl sulphate (K12) as whipping agent, playing significant feature in mortar is to disperse and foaming, it separately stable existence in the face table of sand grains, as having increased fine aggregate, play lubrication, in the mortar whipping process, produce many micro-bubbles, make that air content increases, molten amount is little, workability, the water-retentivity aspect is improved, and reaches the whole lime effects that replace in the mixed mortar.The foam degree has lacked and has influenced the workability of mortar in order also to influence the intensity of mortar in mortar, and water-retentivity does not reach the purpose that replaces lime, in order to improve mortar strength, improves the workability of mortar, and water-retentivity below is the technical indicator of this product.

The key technical indexes:

Project	Index

PH value (1% concentration)	??????8-10	Outward appearance	Yellow powder shape
PH value (1% concentration)	??????8-10	Foam degree (20 ℃ of 1% concentration)	?????50～60

Foam height (20 ℃ of 1% concentration) (hand)	56～70 milliliters	Foam time	6～8 hours

The gordian technique of this product is to select for use cheap natural sepiolite powder as sorbent material, it is a kind of tubulose powder, adsorptive power is strong, the aqueous work in-process of effective the present invention all can be adsorbed the powdering goods, in dropping into water, can all discharge the absorption working substance in the water outlet again, form little foam and improve the workability and the water-retentivity of mortar, and be not prone to demixing phenomenon.Also need not use the hot water dissolving, easy to use, product performance can obtain quite stable again, and, aqua product solved the too high problem of Packing Fee that easily undermines of packing in transit again because being become powder product, give to store to transport and all brought convenience, the packing of agent shape micro foam agent needs to pack with plastic tank, now makes powder product and can change woven bag packing, its remarkable in economical benefits into.
