The invention belongs to the technical field of water-soluble polymer material, and in particular relates to a preparation method of a high-solid content polypropylene papermaking reinforcing agent. According to the method, raw materials such as acrylamide, crylic acid, ammonium persulfate and sodium sulfite are adopted to prepare a papermaking reinforcing agent through an aqueous solution polymerization technology, so that problems of low solid content and poor water solubility in the prior art are solved. By utilizing the preparation method, the polymer molecular weight and solid content are improved, the transportation cost and production cost are effectively lowered, and the obtained product has reinforcing, retension and dispersing effects and good dissolvability and can be completely dissolved in the water after soaking in the water, so that the utilization rate of the product is increased, and the product has a wide market prospect and an obvious economic benefit.

The invention belongs to the field of water environment treatment, and particularly relates to a preparation method and application of a hydroxyethyl cellulose modified scale inhibitor capable of effectively inhibiting silicon dioxide scale bodies in a green and efficient manner. The green modified cellulose scale inhibitor is prepared by taking hydroxyethyl cellulose as a raw material, ammonium persulfate as an initiator and N-(3-dimethylaminopropyl) methacrylamide as a grafting monomer through a grafting reaction. According to the method, a grafting chain containing an amide group and a tertiary amine group can be introduced to a cellulose molecular chain, so that scale forming substances can be effectively dispersed, and the efficient environment-friendly scale inhibitor is obtained. The scale inhibitor prepared by the invention can effectively inhibit the generation of scale bodies and prevent the size of the scale bodies from being increased; when the scale inhibitor is applied to a reverse osmosis system, the reduction of membrane flux is effectively relieved, and the membrane has a good application prospect in controlling silicon dioxide scaling on the surface of the reverse osmosis membrane.
