Problems solved by technology

[0002] At present, domestic transparent products are mainly based on organotin heat stabilizers, but organotin is expensive and most varieties have bad smell, and tin is a heavy metal, and the toxicity issue has been controversial
Although hydrotalcite can improve the performance to a certain extent, because hydrotalcite is an inorganic substance, it has poor compatibility with PVC powder. When the filling amount is large, it is easy to cause uneven dispersion, brittle products, decreased mechanical properties, and product transparency. , stability can not meet the requirements

Abstract

The invention discloses an efficient powder heat stabilizer and a preparation method thereof as well as the application thereof to an ultra-transparent PVC (polyvinyl chloride) product. The efficientpowder heat stabilizer is prepared from 50 to 80 parts of ultrafine hydrotalcite, 1 to 5 parts of a coupling agent, 8 to 20 parts of zinc salt, 3 to 8 parts of triscyanuric acid, 5 to 15 parts of beta-diketone, 1 to 5 parts of an antioxidant and 0 to 10 parts of silicon dioxide. The compatibility between the heat stabilizer disclosed by the invention and a PVC powder is obviously improved, so thatthe PVC product has more excellent heat stability, weather resistance and transparency. The efficient powder heat stabilizer is applied to PVC transparent and ultra-transparent products.

Description

technical field [0001] The invention relates to a heat stabilizer, more specifically, the invention relates to a high-efficiency powder heat stabilizer and its application in ultra-transparent PVC products. Background technique [0002] At present, most domestic transparent products are mainly based on organotin heat stabilizers, but organotin is expensive and most varieties have a bad smell, and tin is a heavy metal, and its toxicity has been controversial. Other transparent heat stabilizers are mostly liquid stabilizers, and the solvents are complex and diverse, which often have a negative impact on product plasticization. Domestic research and application of powder zinc-based transparent heat stabilizers are less. [0003] Domestic powder zinc-based heat stabilizers are mostly blended with several raw materials, which can meet general product applications. In the case of transparency and long-term stability requirements, a large amount of hydrotalcite is often filled to...
