Example Embodiment
[0026] Example 1
[0027] This embodiment is composed of the following components by weight percentage: 87.3% of naphthalene-based superplasticizer, 8.2% of polyethylene glycol, 2.5% of neopentyl glycol, and 2.0% of xanthan gum.
[0028] After weighing each component by weight, firstly add 87.3% of naphthalene-based superplasticizer into the reaction kettle, heat it to 50-60°C, and then add the shrinkage-reducing component polyethylene glycol 8.2 in turn every 10-15 minutes % and neopentyl glycol 2.5% are stirred until completely dissolved, maintain the temperature of the reactor at 50-60°C, continue to stir for 30 minutes and then cool down to 30-40°C, add the thickening component xanthan gum 2.0%, and continue stirring for 30 minutes until Cool to room temperature and the product is complete.
Example Embodiment
[0029] Example 2
[0030] The method is basically the same as that of Example 1, except that the raw materials are different. This example is composed of the following components according to weight percentage: 88.1% of naphthalene-based superplasticizer, 9.7% of polyethylene glycol, carboxymethyl cellulose 2.2%.
Example Embodiment
[0031] Example 3
[0032] The method is basically the same as that of Example 1, except that the raw materials are different. This example is composed of the following components according to weight percentage: 95.0% of naphthalene-based superplasticizer, 3.5% of neopentyl glycol, 1.5% of xanthan gum %.
