Problems solved by technology

[0003] Calcium zinc stabilizer is made of calcium salt, zinc salt, lubricant, antioxidant, etc. as the main components, and is made by corresponding composite technology. Calcium zinc stabilizer is usually divided into powder calcium zinc stabilizer and liquid calcium zinc stabilizer , the liquid calcium zinc stabilizer has good compatibility with resin and plasticizer, good transparency, and is not easy to precipitate, but its lubricity is poor, which will reduce the softening point of the product, and will deteriorate in long-term storage; solid calcium zinc stabilizer according to Its appearance can be divided into powder form, which is characterized by good lubricity and will not reduce the softening point of PVC hard products, but poor compatibility, precipitation and blooming, easy to absorb moisture, poor dispersion, easy to appear white spots, Scratches, etc., affect the quality of PVC products

Abstract

The invention discloses a nanoemulsion calcium-zinc stabilizer for PVC products, which is composed of the following raw materials in parts by weight: powder calcium-zinc composite stabilizer: 30-40 parts, liquid calcium-zinc composite stabilizer: 20-30 parts, emulsified Agent: 30-40 parts, auxiliary agent: 10-20 parts; the powder calcium-zinc composite stabilizer includes: 30-60 parts of main stabilizer, 10-40 parts of auxiliary stabilizer, 5-35 parts of antioxidant, 0.1-2 parts of ultraviolet absorber, 0.2-1 part of light stabilizer, and 1-15 parts of lubricant; adopting the nanoemulsion calcium-zinc stabilizer of the present invention can solve the problem of poor lubricity of a single liquid stabilizer and reduce the softening of products Points, long-term storage will deteriorate, and the single powder stabilizer has poor compatibility, easy to precipitate and bloom, and easy to absorb moisture, poor dispersibility, easy to appear white spots, scratches and other problems, and solve the problem of powder stabilizer Compatibility and dispersibility problems during production with liquid stabilizers ensure better product performance and a smoother finished product surface.

Description

technical field [0001] The invention relates to the technical field of PVC heat stabilizers, in particular to a nanoemulsion calcium-zinc stabilizer for PVC products and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose plastics. Due to its excellent comprehensive performance and low price, it has been widely used in various fields, and its consumption is second only to polyethylene. However, due to the poor thermal stability of PVC, it is necessary to add an appropriate amount of heat stabilizer to inhibit the degradation of PVC during processing. At present, the commonly used human stabilizers can be roughly divided into lead salts, metal soaps, organotins, and rare earth heat stabilizers. Under the main theme of global environmental protection, the highly toxic lead salt heat stabilizers are gradually withdrawing from the market, the organotin heat stabilizers with superior performance are difficult to...
