Method For Preparing Polycarboxylate Superplasticizer Synthesized At Room Temperature:
The invention relates to the technical field of building material admixtures and in particular relates to a polycarboxylate superplasticizer synthesized at room temperature and a preparation method thereof. The preparation method comprises the following steps: adding unsaturated polyether methyl allyl polyoxyethylene ether, hydrogen peroxide and 2-acrylamide tetradecyl sulfonic acid into deionized water to prepare a base solution; dripping a solution A consisting of acrylic acid, methacrylic acid and a chain transfer agent mercaptoacetic acid and an aqueous solution of vitamin C, stirring uniformly, carrying out a free radical polymerization reaction at the room temperature, and regulating the pH value of the reaction system to be 6-7 by using liquid caustic soda after the reaction is ended, thereby obtaining the polycarboxylate superplasticizer. The polycarboxylate superplasticizer obtained by the invention can maintain long-lasting dispersity, has long branched chains, is good in dispersion stability, simple in preparation process and low in energy consumption, can be synthesized at the room temperature and has good economic benefits.
Motar Performance:
1. It is homologous between water-reducing rate of motar and fluidity of cement paste. The more fluidity of cement paste, the more water-reducing rate of motar.
2. Water-reducing rate increases fast and high when the dosage increase. When the dosage is same, the water-reducing rate of PCE powder is 35% higher than that of other superplasticizer in market.
3. Due to the influence from the admixture and sand coarse aggregate, Water-reducing rate in concrete is different from that of motar. When the the admixture and sand coarse aggregate are in favour of the concrete flow, the water-reducing rate of concrete is higher than that of motar.
4. It has antifreezing performance when temperature is above -5ºC. So it can be used in antifreezing concrete.
Polycarboxylate Superplasticizer Product Features:
1. High water reduction rate: it can make the water reduction rate reach more than 25%, and greatly improve the fluidity
under the condition of the same amount of water added to the concrete;
2. high slump resistance: in the spray drying process, the carboxylic group will cause more or less damage to the
traditional polycarboxylate superplasticizer. So as to greatly reduce the slump retention performance after the liquid is
ransformed into solid. Sp-409 is manufactured by a special process, so that the carboxylic acid group is not damaged
in the powder manufacturing process, so as to retain the slump retention of the original liquid mother liquor.
3. Good solubility and fast dissolution rate: due to its uniform particles and large specific surface area. Therefore, it can
be dissolved quickly in the process of water dissolution. And there are no obvious impurities after dissolution.
Scope of Application:
1. Suitable for long-distance construction projects type pumping concrete.
2. Suitable for compounding normal concrete,high-performance concrete,high-strength concrete and ultra-high strength concrete.
3. Suitable for impervious,antifreezed and high durability concrete.
4. Suitable for high-performance and high flowing concrete,self-leveling concrete,fair-faced concrete and SCC(self compact concrete).
5. Suitable for high dosage of mineral powder type concrete.
6. Suitable for mass concrete that used in expressway,railway,bridge,tunnel,water conservancy projects,ports,wharf,underground etc.
