Formula for metal borophosphate ammonium salt flame-retardant and smoke-suppressing wood-plastic composite material

Abstract

The invention relates to the technical field of wood-plastic composite material formulas, and specifically discloses a formula for a metal borophosphate ammonium salt flame-retardant and smoke-suppressing wood-plastic composite material. The metal borophosphate ammonium salt flame-retardant and smoke-suppressing wood-plastic composite material is prepared from the following raw materials in partsby weight: 100 to 300 parts of thermoplastic plastic, 100 to 600 parts of wood fiber, 0 to 6 parts of a stabilizer, 0.75 to 20 parts of a lubricant, 4.5 to 80 parts of a coupling agent and 5 to 15 parts of a metal borophosphate ammonium salt flame-retardant and smoke-suppressing agent. The formula provided by the invention overcomes disadvantages of the prior art; and compared with a conventionalflame-retardant wood-plastic composite material, the flame-retardant and smoke-suppressing wood-plastic composite material prepared by utilizing the formula provided by the invention has small addition amount of a flame-retardant and smoke-suppressing agent and has a multi-pore-channel structure with excellent adsorption effect to smoke.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite material formulations, in particular to a formula of metal ammonium borophosphate flame-retardant and smoke-suppressing wood-plastic composite material. Background technique [0002] Wood-plastic composite material is a kind of wood fiber material (WF) in the form of fiber and powder as filling or reinforcing material, with thermoplastic as matrix material, adding various additives through extrusion, hot pressing, molding or injection molding, etc. A new type of composite material made by combining various processing methods. Commonly used thermoplastic substrates include polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC). Wood-plastic composite materials without fire-resistant and flame-retardant treatment are easy to burn, and have a large calorific value of combustion. At the same time, wood-plastic composite materials using PS and PVC plastic s...
