Abstract

The invention discloses a stone-wood-plastic material which is prepared from heavy calcium carbonate powder, polyhexylene plastic, poplar powder, an adhesive, fatty acid amide, silica gel, a flame retardant, a smoke inhibitor, an aerosol generator, a titanate coupling agent, a PP-g-MAH (polypropylene graft maleic anhydride) compatilizer, a WINGSTAYL antioxidant, a JINHASS regulator, a reinforcer, polyaluminum ferric chloride, di-n-octyl phthalate, potassium stearate and styrene. The stone-wood-plastic material has the advantages of favorable flame-retardant effect, high impact resistance, high toughness and low water absorptivity, obtains excellent flame retardancy on the premise of keeping favorable mechanical properties of the stone-wood-plastic material, is a stone-wood-plastic material with favorable properties, can be widely used for decorating hotels, restaurants and buildings, and has obvious economic and social benefits.

Description

technical field [0001] The invention belongs to the field of wood-plastic material preparation technology and environmental protection, and specifically relates to a stone-wood-plastic material. Background technique [0002] Wood-plastic composite (WPC) is a composite material mainly made of wood or cellulose as the base material and plastic. It is a certain proportion of wood fibers (such as wood powder, straw powder, cotton stalk powder, bamboo powder, Nutshell powder, etc.) is a new type of material that is pretreated to combine it with thermoplastic polymer resin or other materials; this new type of material is both environmentally friendly and has good mechanical stability, but the two major components of wood-plastic composites Both raw wood fiber and polyolefin are flammable materials, so the composite material is also a flammable material. It is the need for the application and development of the material to endow the wood-plastic composite material with good flame r...
