Description
Technical Field
The application relates to the technical field of PVC resin production, in particular to an extinction resin production device.
Background
The extinction polyvinyl chloride resin is a polyvinyl chloride resin with a chemical micro-crosslinking structure. It is a compound which can be copolymerized with vinyl chloride and can make polyvinyl chloride molecular chain crosslink and is added in the course of polymerization of vinyl chloride, and the commonly used monomer (i.e. crosslinking agent) with two or more vinyl groups. The polyvinyl chloride is partially crosslinked by controlling the addition amount of the crosslinking agent. The product processed by the partially crosslinked polyvinyl chloride resin has the advantages that due to the existence of the microgel, the viscoelasticity of gel and sol components is different, micro concave-convex can be formed on the surface of the product, and when light irradiates the surface of the product, diffuse reflection occurs, so that the specular reflection on the surface of the product is reduced, and the extinction performance is shown. Due to the existence of the gel part, the product has lower permanent deformation, thus meeting the requirements of low gloss or surface extinction in the fields of packaging, building materials, vehicles, furniture and the like. In addition, after the PVC is crosslinked, the heat distortion resistance, the solvent resistance and the aging resistance of the PVC can be improved, and the physical and mechanical properties and the electrical properties of the PVC are changed. The extinction resin can be used for manufacturing extinction plastic products independently, and can also be used by being blended with common resin. But different methods of use have different requirements on the properties of the resin. For single use, the gel content is desirably as low as possible, and the requirement of extinction is met; for blending use, the gel content of the synthetic matte resin should be high.

When the resin is processed, under the control of a certain plasticizing temperature and plasticizing time, the resin is made into a partially molten state, and is formed into a delustred product whose surface possesses fine and coarse grains so as to attain the goal of delustring product.
