High viscosity polyvinyl chloride paste resin PE1311 and preparation method thereof

Abstract

The invention provides a high viscosity polyvinyl chloride paste resin PE1311 and a preparation method thereof. The high viscosity polyvinyl chloride paste resin PE1311 is prepared from raw materials comprising, by weight part ratio, 100-600 parts of vinyl chloride monomer, 100-600 parts of water, 1-10 parts of sodium persulfate, 1-10 parts of ferrous sulfate, 1-5 parts of sodium laurate, 10-50 parts of sodium dodecyl benzene sulfonate and 1-5 parts of sodium formaldehyde sulfoxylate. The preparation method includes: adopting an emulsion polymerization method for producing, adding monomers and addition agents into a polymerizing pot according to the weight part ratio, exhausting oxygen, aerating nitrogen, raising temperature to 50-60 DEG C under a stirring state, maintaining the temperature for a polymerization reaction, and finishing the reaction when pressure reaches 10MPa. The preparation method is simple in technology and easy to operate, and furthermore the produced product has the advantages of being high in paste viscosity, high in foaming ratio and good in rheological property.

AI Technical Summary

Benefits of technology

This patented technology describes making highly concentrated or clear liquid plastics with specific properties such as low stickiness (low gloss) at room temperatures). These liquids are made from vinylchloride monomer solution which contains iron salts like Ferrum Sulfate for better stability during storage over time without losing their desired qualities.

Problems solved by technology

This patented technology describes different methods for producing plastic materials called polystyrene (PS) particles or vinylchloride (VCM). These techniques involve reactants containing certain chemical compounds together through heat treatment at specific temperatures. By controllably varying these parameters during processing, desired properties such as particle sizes are achieved without affecting stability over time. However, this results in decreased production efficiency due to increased costs associated with post-processing operations like cleanings and solvent extraction processes. To solve this problem, we have developed an improved version of the original formulation described earlier on how to achieve better quality products from PS particles.
