Polycarboxylate Superplasticizer Abstract:
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.
Characteristics:
As a universal and economical product, JF-PCE is recommended for production of flowing mortars with normal and special cementitious binder system due to the following characteristics
1. Super water reducing effect for cement based material applications
2. Low dosage compared to traditional water reducing agent
3. High dispersion, fluidity and workability.
4. Improvement of early and final strength of cement based system
PCE Advantage:
1. High water reduction rate: its maximum water reduction rate can reach 30%.
2. Good dispersion
3. High adaptability
4. Early strength and high strength
5. High durability
6. Good adaptability
7. Green: No formaldehyde and other harmful ingredients.
Safety And Precautions of Polycarboxylate Superplasticizer Powder:
1. Polycarboxylate superplasticizer powder is a weakly alkaline solid, non-toxic, non corrosive and non polluting to the environment. However, it is not edible. When it comes into contact with human body and eyes, it should be washed with clean water as soon as possible. If it causes allergy to some human bodies, it should be treated in time.
2. Polycarboxylate superplasticizer powder should be stored in a cardboard bucket lined with plastic bags to avoid the mixing of rain water and sundries.
3. The shelf life of polycarboxylate superplasticizer powder is 12 months.
