Abstract
The present invention relates to a lubricating agent prepared from polyalcohol and grease by the reaction of ester exchange for the processing industry of polyvinyl chloride plastics. The present invention is polyalcohol fatty acid ester which is prepared from polyalcohol(glycerol or polyglycerine) and grease (animal grease or vegetable grease) under the protection of nitrogen and the catalysis of catalysts. The present invention has favorable quality of products, and the performance indexes reach the level of the similar foreign products. The present invention fills the blank of the type of inner lubricating agents in the processing industry of plastics in China.
Description
The present invention relates to a kind of preparation method of polyhydric alcohol fatty acid ester, belong to the industrial lubricant category of plastic working, particularly igelite processing industry with lubricator.
Adding lubricant in the plastic formula, is in order to improve resin flow when the forming process.Some resin such as polyvinyl chloride and ABS etc. must add lubricant in the course of processing, for polyvinyl chloride hard goods, all the more so especially.
Plastics with lubricator according to its mode of action, can be divided into external lubricant and internal lubricant two big classes.Internal lubricant can reduce the force of cohesion between polymer molecule, works effects such as quickening fusion, reduction melt viscosity, prolongation processing life-span, improve liquidity and improve the transparency.
Polyhydric alcohol fatty acid ester is a kind of plastic working industry internal lubricant commonly used.At present, domestic igelite processing industry.Mainly be to rely on this series products (as the Loxiol G16 of West Germany's Henkel (Henkel) company) of import to produce.
The processing condition of the Loxiol G16 product of West Germany's Henkel (Henkel) company are not reported.
Purpose of the present invention is to develop a kind of suitable internal lubricant for domestic igelite processing industry.
We have succeeded in developing the preparation method of polyhydric alcohol fatty acid ester.
Polyhydric alcohol fatty acid ester with method provided by the invention is made through probationary certificate, can reduce melt torque and melt temperature, promote plasticizing, shorten fusion time, improve the thermal shear stability of material, eliminate wall sticking phenomenon, except that significantly interior lubrication, and certain outer lubrication is arranged, and the material non-stick pan, color is normal, the Loxiol G16 of quality and West Germany's Henkel (Henkel) company is suitable, has reached purpose of the present invention.
