Problems solved by technology

At present, the traditional PVC stabilizers mainly include lead salts, organotins, metal soaps and rare earths, among which lead salts and heavy metals are poisonous and harmful substances, and have gradually withdrawn from the stabilizer market; organotin stabilizers are still ineffective. Yes, and can be used for transparent products, but the price is higher; ordinary metal soaps have poor thermal stability; rare earths are a relatively new type of stabilizer, but affected by the shortage of rare earth resources, their prices are constantly rising, so It is of great significance to develop a stabilizer with reasonable price and good performance
[0004] At present, in the traditional PVC stabilizer formula, there are still problems such as the use of zinc stearate alone, resulting in low grinding efficiency, and the lubricity and compatibility of the compound to PVC. Inadequately poor, and in the compounding process of PVC stabilizer, the use of large particles of 16-18 alcohol has brought about the problem of difficult grinding powder, which also makes the compounding process complicated

Abstract

The invention relates to a fatty acid calcium zinc composite and a preparing method thereof. The fatty acid calcium zinc composite is composed of stearic acid or lauric acid, 12-hydroxystearic acid, adipic acid or 2-benzoic acid, calcium hydroxide or calcium oxide and 16-18 alcohol by a certain proportion. The fatty acid calcium zinc composite is used for preparing polyvinyl chloride (PVC) stabilizer and capable of overcoming the defect that in a traditional PVC stabilizer formula, when zinc stearate is used independently, the zinc stearate is difficult to grind. Relative to the zinc stearate, the fatty acid calcium zinc composite is capable of improving content of zinc in a monomer. The fatty acid calcium zinc composite is enabled to has a good inner-outer lubricating property to the PVC, compatibility of the fatty acid calcium zinc composite and the PVC is improved, the preparing that the 16-18 alcohol used in the compounding process of the traditional PVC stabilizer is added into the fatty acid calcium zinc composite in advance is achieved, the problem that the 6-18 alcohol is big in particles and difficult to grind in the traditional compounding process of the PVC stabilizer is resolved, compounding procedures are simplified, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a composition and a preparation method thereof, in particular to a fatty acid calcium zinc composition and a preparation method thereof. Background technique [0002] Polyethylene (PVC) material has been widely used because of its wide application, good processing performance, low manufacturing cost, corrosion resistance, insulation and other good characteristics. At present, PVC materials and related products can be seen everywhere in people's lives, such as PVC foam materials, PVC stationery, PVC threading pipes, PVC cable insulation, PVC water pipes and other pipes, PVC plastic doors and windows, PVC plastic bags, PVC film, PVC leather etc. In actual use, PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives to make them have excellent stability, toughness, ductility, strength, weather resistance and excellent Excellent physical and chemical p...
