Abstract

The invention belongs to the application field of high polymer materials, and relates to an iron phosphomolybdate smoke suppression PVC plate and a preparation method thereof. The iron phosphomolybdate smoke suppression PVC plate comprises the following components in parts by weight: 100 parts of PVC resin powder, 2-3 parts of a stabilizer, 2-3 parts of a processing aid, 0.5-1 part of a lubricant,3-5 parts of a flexibilizer, 8-15 parts of a filler, and 4-6 parts of a flame-retardant smoke suppressant. According to the iron phosphomolybdate smoke suppression PVC plate provided by the invention, phosphomolybdic acid and ferric hydroxide are used as raw materials, the iron phosphomolybdate prepared by a hydrothermal method is used as a flame-retardant smoke suppressant, and is added to PVC plate production in combination with other additives, the process is simple, the yield is high, and the flame-retardant and smoke-suppression effect is obvious.

Description

technical field [0001] The invention belongs to the application field of polymer materials, and relates to an iron phosphomolybdate smoke-suppressing PVC plate and a preparation method thereof. Background technique [0002] PVC is one of the five major synthetic thermoplastics, its output is second only to polyethylene, and PVC is mainly hard products. PVC sheets are widely used in advertising, packaging and decoration industries, and are developing at a relatively fast speed. However, the burning process of PVC sheet produces a lot of smoke, which limits its application in advertising and decoration materials. Therefore, improving the flame retardancy and smoke suppression of PVC sheet is the key to the development and application of PVC sheet, and it is of great significance to promote its application in related industries. [0003] Traditional smoke suppressants are expensive and not environmentally friendly. At present, the main commercially used smoke suppressant is ...
