Abstract

The invention discloses a flame-retarding type PVC (Polyvinyl Chloride) foaming board and a preparation method thereof and belongs to the technical field of PVC foaming boards. The flame-retarding type PVC foaming board is prepared from the following raw materials in parts by weight: 100 parts of PVC with the average degree of polymerization, 2-7 parts of foaming regulator, 0.5-0.8 part of foamingagent, 3-8 parts of brominated polyphenyl ether, 2-5 parts of urea, 3-5 parts of calcium-zinc stabilizer, 2-5 parts of barium stearate, 5-12 parts of nanometer light calcium carbonate, 25-35 parts ofwood meal, 0.4-0.6 part of aluminium stearate, 0.6-0.8 part of oxidized polyethlene wax and 40-50 parts of dioctyl phthalate. The flame-retarding type PVC foaming board and the preparation method disclosed by the invention has the beneficial effects that by addition of the flame-retarding agent brominated polyphenyl ether and urea into a production formula of the PVC foaming board, the prepared PVC foaming board has good flame-retarding property, and the safety property of the PVC foaming board is improved; simultaneously, by combination with other additives, the toughness and the mechanicalstrength of the PVC foaming board are also improved.

Description

technical field [0001] The invention relates to the technical field of PVC foam board production, in particular to a flame-retardant PVC foam board and a preparation method thereof. Background technique [0002] PVC foam board, also known as Chevron board and Andy board, uses polyvinyl chloride (PVC) as the main raw material and adds various additives. It is a new type of green and environmentally friendly material. At present, the PVC industry is developing rapidly all over the world with broad prospects.
