Grain fiber wood-like composite material and manufacturing method thereof

Abstract

The invention discloses a composition for manufacturing a grain fiber wood-like composite material. The composition is characterized by comprising the following components: 50 to 60% by weight of PVC resin, preferably 55 to 60% by weight of the PVC resin, more preferably 57 to 59% by weight of the PVC resin; 4 to 8% by weight of an impact modifier, preferably 5 to 7% by weight of the impact modifier, more preferably 4.5 to 6.5% by weight of the impact modifier; 1 to 5% by weight of a processing aid, preferably 1 to 4% by weight of the processing aid, more preferably 1 to 2% by weight of the processing aid; 1 to 4% by weight of a lubricant, preferably 1 to 3% by weight of the lubricant, more preferably 2 to 3% by weight of the lubricant; 8 to 10% by weight of a composite stabilizer, preferably 4 to 6% by weight of the composite stabilizer; 12 to 17 wt% by weight of rice hull powder, preferably 13 to 16 by weight of the rice hull powder; and 10 to 17% by weight of calcium carbonate, preferably 12 to 16% by weight of the calcium carbonate, more preferably 13 to 14% by weight of the calcium carbonate. The invention also discloses a preparation method of the composition.

Description

technical field [0001] The invention relates to a grain fiber imitation wood composite material, in particular to a grain fiber imitation wood composite material which can be applied to building components, in particular, can be used as door and window profiles. The invention also relates to a manufacturing method of the grain fiber imitation wood composite material. Background technique [0002] With the advancement of technology and industrial technology, a wood-plastic composite material (WPC) has appeared on the market. Wood-plastic composite materials are mixed and extruded from wood fibers or other plant fibers with resin materials and other small amounts of additives. Therefore, It is in a multiphase state of crystalline (wood fiber or plant fiber) and disordered state (resin), which has both the high strength and high elasticity of wood fiber or plant fiber, and the high toughness and fatigue resistance of the polymer matrix. , so it has excellent comprehensive perf...
