Abstract

The present invention discloses a novel environmental-friendly flame retardant for PVC. A formulation includes the following components by weight: 5-10 parts of sodium sulphide, 3-6 parts of calcium sulfate, 5-6 parts of Sb2O3, 6-7 parts of barium metaborate, 10-15 parts of corn flour, 5-8 parts of barium sulfide, 4-6 parts of zinc sulfide, and 5-10 parts of a coupling agent. The flame retardant of the present invention is simple in preparation, stable in properties, good in compatibility with PVC, good in flame-retardant effect, and small in usage amount, and helps to reduce harmful gas evaporation.

Description

technical field [0001] The invention relates to a flame retardant, in particular to a novel environmentally friendly flame retardant for PVC. Background technique [0002] At present, the flame retardants used in the market are more expensive, and the flame retardant effect is not ideal, and a large amount of harmful gas will still overflow during flame retardant. However, intumescent flame retardants with good quality are difficult to meet the market demand due to the high difficulty of the preparation process. Contents of the invention [0003] The purpose of the present invention is to provide a novel environmentally friendly flame retardant for PVC in view of the deficiencies in the prior art. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is as follows: a novel environmentally friendly flame retardant for PVC, the formula is composed of the following components in parts by weight: 5-10 parts of sodium sulfide, 3-6...
