example 1

[0032] Example 1: In a dry four-necked flask equipped with a stirrer, a reflux condenser and a thermometer, under N 2 Under atmosphere, put 600g of allyl polyethylene glycol monoether with ethyleneoxy polymerization degree n of 45 and average molecular weight of 2000 into a flask, heat to 40°C and melt, then add 35g of anhydrous orthophosphoric acid and allylpolyethylene glycol monoether Mix ethylene glycol monoether, heat up to 55°C under rapid mechanical stirring, react with temperature control for 3.5 hours, then cool to room temperature to obtain light yellow transparent viscous liquid allyl polyethylene glycol monoether phosphate monomer. Weigh 210g above-mentioned allyl polyethylene glycol monoether phosphate monomer and dissolve in 20g distilled water, pour in the flask and stir; 2Add 36g of acrylic acid (dissolved in 100g of distilled water) and 5g of sodium superphosphate (dissolved in 25g of distilled water) and 4.36g of 7-allyloxy-4-methylcoumarin at the same time d...

Abstract

The invention discloses a phosphorus spectrum and fluorescent double tracer polycarboxylate superplasticizer with a structural general formula described as follows, wherein R1' is -H, -M (M is H + or K + or Na + or NH4 +) or ; R2 is -H, -M (M is H + or K + or Na + or NH4 +) or is ; phosphorus oxygen bond oxygen atoms are connected to the * position; R1 is -H or -COOH; R2 and R3 are low carbon alkyls of -H or C1-C4; the number of repeating units m is 0 to 10, the number of repeating units n is 0 to 100, the degree of polymerization x is 1 to 500, the degree of polymerization y is 1 to 5,000, and the degree of polymerization z is 1 to 5000. The polymer as the superplasticizer has excellent dispersion properties with smaller parameters and a greater mobility, low solid parameters can greatly reduce costs and increase efficiency, and synthetic raw materials are non-toxic and harmless, and synthetic products do not need to be separated, accord with characteristics of cleaner production and are suitable for marketing.

Description

technical field [0001] The invention belongs to the technical field of polymer synthesis, and in particular relates to a phosphorus spectrum and fluorescent double tracer polycarboxylate water reducer and a preparation method thereof. Background technique [0002] In recent years, with the continuous increase of my country's investment in infrastructure construction, the development of the domestic construction industry is also changing with each passing day, and the demand for concrete superplasticizers is also increasing year by year. Faced with the real problem of high-efficiency superplasticizer foreign raw materials are expensive, the domestic raw material market has been established and matured day by day. Therefore, my country's construction industry urgently needs high-performance concrete technology that adapts to the domestic market, and high-efficiency water reducer technology and products that fully realize the localization of raw materials. [0003] However, th...
