Description
Technical Field
The invention belongs to the technical field of stabilizers, and particularly relates to a calcium-zinc stabilizer for improving comprehensive performance of CPVC and a preparation method thereof.
Background
CPVC is a novel engineering plastic with wide application prospect. The resin is prepared by chlorination modification of polyvinyl chloride (PVC) resin, and is a novel engineering plastic. The product is white or light yellow, odorless, and nontoxic loose granule or powder. After the PVC resin is chlorinated, the irregularity of molecular bonds is increased, the polarity is increased, the solubility of the resin is increased, and the chemical stability is increased, so that the heat resistance, the acid resistance, the alkali resistance, the salt resistance, the oxidant resistance and the like of the material are improved. The mechanical property of the thermal deformation temperature of the numerical value is improved, the chlorine content is improved from 56.7 percent to 63-69 percent, the Vicat softening temperature is improved from 72-82 ℃ to 90-125 ℃, the maximum use temperature can reach 110 ℃, and the long-term use temperature is 95 ℃.
It is well known that the performance of stabilizers has a large impact on the stability of CPVC materials. The commonly used heat stabilizer is mainly a lead salt stabilizer, which has low price and good heat stabilizing effect, but has high toxicity, seriously harms human health and pollutes the environment. The non-toxic calcium-zinc composite Ca/Zn heat stabilizer is a world-recognized non-toxic and environment-friendly heat stabilizer, has the advantages of low price, good lubricity and the like, and has a very wide development space.
However, CPVC stabilizers currently used in the market are poor in weatherability, easily discolored, and when added at a high content, the strength of the CPVC material is significantly reduced. Therefore, there is a need to develop a calcium zinc stabilizer for improving the combination properties of CPVC.
