Problems solved by technology

Rare earth heat stabilizers have good thermal stability, but the early thermal stability is not high, and the initial coloring is poor, so they cannot be the main stabilizer alone, so their application and promotion are limited. The application of a single rare earth heat stabilizer is often difficult to meet the needs of PVC processing. Composite and multi-functional rare earth heat stabilizers have become the development trend according to the requirements of application performance

Abstract

The invention relates to an environmental protection PVC section bar organic tin stabilizing agent. The environmental protection PVC section bar organic tin stabilizing agent comprises 69 to 75 partsof organic tin, 19 to 25 parts of organic zinc, 12 to 16 parts of an antimony based stabilizing agent, 21 to 25 parts of epoxy resin, 9 to 14 parts of modified magnesium aluminum hydrotalcite, 9 to 12parts of stearic acid, 5 to 11 parts of calcium stearate, 4 to 8 parts of nanometer zinc oxide, 5 to 9 parts of nanometer titanium dioxide, 15 to 21 parts of light calcium carbonate, 9 to 15 parts ofparaffin oil, and 15 to 25 parts of a phosphite ester. The environmental protection PVC section bar organic tin stabilizing agent is prepared from novel environment-friendly materials at a scientificand reasonable ratio, conventional environment protection safe raw materials are adopted, so that excellent heat stability and processing performance are achieved; the environmental protection PVC section bar organic tin stabilizing agent possesses excellent heat stability and processing performance, is nontoxic, is friendly to the environment, is low in cost; in PVC processing process, the plasticizing performance is excellent, balance torque is reduced; the light transparency is excellent; cost is low; heat stability is increased; and section bar welding strength is high.

Description

technical field [0001] The invention relates to the technical field of environment-friendly stabilizers, in particular to an environment-friendly organic tin stabilizer for PVC profiles. Background technique [0002] With its superior physical properties and low cost, PVC is widely used in chemical industry, materials, machinery, agriculture, daily necessities and other fields, especially in the field of plastics, and is known as one of the five general-purpose plastics. However, PVC has a very important defect, that is, it is easy to decompose and produce hydrogen chloride gas during thermal processing, and self-catalysis leads to severe degradation of PVC, which affects various properties of PVC products, such as discoloring PVC products or reducing its mechanical properties. In order to overcome this defect of PVC, it is mainly to add an appropriate amount of stabilizer during the thermal processing of PVC. [0003] The only heat stabilizers that are generally industrial...
