Abstract

The invention relates to the technical field of polyvinyl chloride resin and in particular to a nanoparticle latex and nanoparticle enhanced and toughened vinyl chloride composite resin and a preparation method thereof. The nanoparticle latex is prepared by the following steps: dissolving acrylate in a crosslinking agent to form a mixed liquid of acrylate and the crosslinking agent; and then by taking deionized water as a solvent, adding an active nanoparticle nucleating agent, an emulsifying agent, an initiator I and a pH value adjustor into the solvent. The preparation method of producing nanoparticle latex is lower, short in synthetic time, simple and easy to control and high in production efficiency; nanoparticles can achieve a dispersing action of nanoscale. By adopting the nanoparticle latex, the nanoparticle enhanced and toughened polyvinyl chloride composite resin which has an interpenetrating coating structure and is better in toughness can be prepared. The nanoparticle enhanced and toughened vinyl chloride composite resin provided by the invention is good in impact resistance, high in tensile strength, short in plastifying time, low in acrylate content, simple in process, short in synthetic time and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride resin, and relates to a preparation method of nano particle latex, nano particle reinforced and toughened vinyl chloride composite resin, nano particle latex, and nano particle reinforced and toughened vinyl chloride composite resin. Background technique [0002] Polyvinyl chloride resin is widely used due to its excellent mechanical properties, chemical resistance, flame retardancy and electrical insulation properties. It is one of the most widely used general-purpose plastics in the world, and its output is second only to polyethylene. Second, it has been widely used in various fields such as construction, chemical industry, electrical instruments, daily necessities, etc. However, since the polyvinyl chloride resin itself is sensitive to the notch, the notched impact strength is low (only 3.0kJ / m 2 Left and right), poor processing flow properties and other shortcomings greatly limit ...
