Flame-retardant ABS wood-plastic profile and preparation method thereof

Abstract

The invention provides a flame-retardant ABS wood-plastic profile. The wood-plastic profile comprises the following raw materials in parts by weight: 80 to 100 parts of ABS resin, 40 to 60 parts of plant fiber powder, 3 to 6 parts of ABS grafted material, 3 to 12 parts of expanded graphite, 2 to 8 parts of silane modified conductive carbon black, 0.1 to 0.4 part of silica gel, 0.2 to 0.8 part of lubricant, 0.5 to 1.5 parts of a flame retardant and 0.5 to 1.5 parts of a smoke suppressant. The invention further provides a preparation method of the flame-retardant ABS wood-plastic profile. The flame retardant, the smoke suppressant, the expanded graphite and the silane modified conductive carbon black are added into the raw materials; wherein the flame retardant and the smoke suppressant enable the wood-plastic profile to have good flame-retardant and smoke-suppressing effects, and toxic and harmful substances cannot be released at high temperature; in addition, the expanded graphite andthe silane modified conductive carbon black enable the wood-plastic profile to maintain good flame-retardant and smoke-suppressing effects, and at the same time, the mechanical properties of the wood-plastic profile can be further improved.

Description

technical field [0001] The invention relates to the technical field of wood-plastic materials, in particular to a flame-retardant ABS wood-plastic profile and a preparation method thereof. Background technique [0002] Wood-plastic composite (WPC) refers to a new type of material made of thermoplastic and wood fiber, which is generally used for outdoor decoration. Although the new material is environmentally friendly and has good mechanical stability, the two major raw materials, wood fiber and polyolefin, are both flammable materials. Therefore, the composite material is also a flammable material. The good flame retardant properties of wood-plastic composites" has become the development trend of this material in the application field. [0003] At present, the flame retardant wood-plastic composite materials on the market all have a certain flame retardant effect, which can delay the spread of the disaster when a fire occurs. However, according to the fire scene in recent ...

AI Technical Summary

Problems solved by technology

However, according to the fire scene in recent years, the flame retardant properties of most of the current flame retardant wood-plastic composite materials still cannot meet the actual needs, and they need to be further improved.
