Phosphomolybdic acid copper antiflaming smoke-suppression PVC (polyvinyl chloride) rigid foamed sheet and preparation method thereof

Abstract

The invention belongs to the field of application of high polymer materials, and relates to a phosphomolybdic acid copper antiflaming smoke-suppression PVC (polyvinyl chloride) rigid foamed sheet anda preparation method thereof. The phosphomolybdic acid copper antiflaming smoke-suppression PVC rigid foamed sheet is prepared from the following ingredients in parts by weight: 100 parts by weight ofPVC resin powder, 3-6 parts by weight of stabilizer, 0.5-2 parts by weight of lubricating agent, 1-3 parts by weight of processing aid, 1-4 parts by weight of foaming agent, 8-25 parts by weight of filler and 3-6 parts by weight of antiflaming smoke-suppression agent. The phosphomolybdic acid copper antiflaming smoke-suppression PVC rigid foamed sheet takes phosphomolybdic acid and basic zinc carbonate as raw materials, the phosphomolybdic acid copper prepared under a water bath condition is adopted as the antiflaming smoke-suppression agent and is combined with other auxiliary agents, the mixture is added into the production of the PVC rigid foamed sheet, a technology is simple, yield is high, and an antiflaming smoke-suppression effect is obvious.

Description

technical field [0001] The invention belongs to the application field of polymer materials, and relates to a copper phosphomolybdate flame-retardant and smoke-suppressing PVC rigid foam board and a preparation method thereof. Background technique [0002] The main chemical composition of PVC foam board is polyvinyl chloride (Polyvinyl chloride), so it is also called foamed polyvinyl chloride board. It is widely used in various fields such as industry, agriculture, transportation, construction, communication, medical care and health, such as industrial spare parts, tarpaulins, water pipes, plastic doors and windows, cable protective sleeves, medical products, etc. Although rigid PVC itself has excellent flame retardant properties, foaming will cause a decrease in the flame retardant properties of PVC materials, and the lower the density, the greater the decrease, especially when it is forced to burn in the air, it will emit a lot of black smoke, while Black smoke is the dead...

Problems solved by technology

Although rigid PVC itself has excellent flame retardant properties, foaming will cause a decrease in the flame retardant properties of PVC materials, and the lower the density, the greater the decrease, especially when it is forced to burn in the air, it will emit a lot of black smoke, while Black smoke is the deadliest factor in fires
