Abstract
The invention discloses a preparing method for degradability-resisting enhancement-type cationic polyacrylamide. The preparing method includes the steps that cationic monomers and acrylamide are copolymerized, and the polymer with quite high degradation resisting capacity is prepared by adding a specific protective agent. The using performance of the polymer is not influenced by the method, an existing device does not need to be changed, the preparing method is simple and practical, and the retention time of 50% viscosity of the polymer can be prolonged to be longer than 40 hours. The largest characteristic is that the degradation resisting capacity is high, and the retention time of the viscosity of the water solution of the polyacrylamide can be prolonged by 5-8 times.

Described cationic monomer is acrylyl oxy-ethyl-trimethyl salmiac, MethacryloyloxyethylTrimethyl Trimethyl Ammonium Chloride.
Described oxine is eliminate to dissolve metal ion contained in water used to the impact of viscosity as the effect of important source material, and its effect is irreplaceable, and the large I of its consumption regulates according to the salinity of local water.
Described HMPA is eliminate to dissolve microorganism contained in water used and External Heat Flux, ultraviolet to the impact of viscosity as the effect of important source material, and its effect is irreplaceable.
Described oxidation inhibitor is antioxidant BHT, and its effect is irreplaceable.
Described initiator is Potassium Persulphate and S-WAT.
The present invention compared with prior art; various raw materials used not only can play the effect of protection molecular chain; various complicated ingredient can also to be eliminated in water on the impact of result of use; therefore in use effect is more stable; maximum feature is that anti-degradation capability is strong, and the viscosity retention time of its aqueous solution can extend 5-8 doubly.
