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soaps and rare earths, among which lead salts and heavy metals are poisonous and harmful substances, and have gradually withdrawn from the stabilizer market; organotin stabilizers are still ineffective.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 composition and a preparation method thereof. The fatty acid calcium zinc composition of the present invention is prepared from the following components in a certain proportion: stearic acid or lauric acid, 12-hydroxystearic acid, adipic acid or dibenzoic acid, calcium hydroxide or calcium oxide, zinc oxide , 16-18 alcohol. The fatty acid calcium zinc composition of the present invention is used for the preparation of PVC stabilizer, can solve the shortcoming of the difficult grinding powder that zinc stearate exists alone in traditional PVC stabilizer formula; The content of zinc; it can make the compound have good internal and external lubricating properties for PVC, and improve the compatibility with PVC; realize the addition of 16-18 alcohol, which is needed in the compounding process of traditional PVC stabilizers, to the combination of fatty acid calcium and zinc in advance The preparation of the compound solves the problem of difficult grinding powder caused by the large 16-18 alcohol particles in the compounding process of the traditional PVC stabilizer, simplifies the compounding process, and greatly improves the production efficiency.

Description

Technical field [0001] The invention involves a composition and its preparation method, which is specifically a calcium composition and preparation method of a fatty acid. Background technique [0002] Polyethylene (PVC) materials have been widely used due to their wide use of their purposes, good processing performance, low manufacturing costs, corrosion resistance, and insulation.At present, PVC materials and related products have been seen everywhere in people's lives, such as PVC foam materials, PVC stationery, PVC thread pipes, PVC cable insulation, PVC water pipes and other pipes, PVC plastic doors and windows, PVC plastic bags, PVC film, PVC film, PVCLeather and other.PVC materials often add stabilizers, lubricants, auxiliary processors, color materials, anti -impacts, and other additives to make it have excellent stability, toughness, ductility, strength, fertility, excellent change, and excellent.Excellent physical and chemical properties such as geometric stability.
