Abstract

The invention belongs to the technical field of POM of plinths of gas mask canisters and particularly relates to a flame-retardant corrosion-resistant POM (polyformaldehyde) plastic formula of a plinth of a gas mask canister and a preparation method thereof. The POM plastic of the plinth is prepared from the following components in parts by weight: 100 parts of POM plastic and PA66 plastic, 5 parts of modified polytetrafluoroethylene PIFE, 35-40 parts of ammonium polyphosphate APP, 12-20 parts of pentaerythritol diphosphate melamine ammonium salt, 5 parts of phenolic resin, 1 part of an antioxidant 2246, 10-15 parts of TPU (thermoplastic polyurethane), 10-15 parts of melamine and 0.1-1.0 part of color masterbatch. The plastic provided by the invention is reasonable in design. The product is flame-retardant corrosion-resistant plinth of the gas mask canister with multiple functions of flame retardance and corrosion resistance.

Description

Technical field [0001] The present invention is the field of anti -virus mask in individual protection equipment, which is specifically for flame retardant corrosion -resistant anti -virus mask tank POM plastic formula and preparation method. Background technique [0002] Polytealdehyde (POM) is an excellent engineering plastic, which is a high -density and high crystalline line polymer. It is widely used in electronic appliances, machinery, instrumentation, automobiles and other fields.In the field of individual respiratory protection equipment, plastic parts as anti -toxic masks have already used POM material plastic parts to obtain examples.EssenceHowever, flame retardant formaldehyde has no manufacturers in China. The plastic used in the market is mainly common POM, with poor flame retardant, and has not been solved well. Invention content [0003] The purpose of the present invention should solve the problem of poor flame retardability used in existing mask and cans. Throug...
