Abstract

The invention discloses a fiber reinforced biomass material and a preparation method thereof. The fiber reinforced biomass material consists of the following components in percentage by mass: 5%-50% of a biomass raw material, 20%-80% of thermoplastic plastic, 5%-40% of a fiber raw material, 10%-30% of other auxiliary materials and 0.5%-20% of aids. According to the preparation method, a biologicalmaterials is pelletized by a double-screw rod pelletizer to prepare a biomass plastic master batch, and the master batch is further prepared into biomass plates and sheets with a profile extruder ora sheet machine. The fiber reinforced biomass material has the beneficial effects of affine textures, water and corrosion resistance, aging resistance, high strength, good flexibility and fracture andscraping resistance, has both the natural texture of natural wood and the strength and durability of a complete plastic material, and is a comprehensive substitutive material of natural wood and complete plastic materials.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a preparation method and application of a fiber-reinforced biomass material. Background technique [0002] At present, the common ones on the market are mainly natural wood and all-plastic materials, and some are biomass composite materials. Due to the requirements of environmental protection, the restrictions on cutting natural wood are becoming more and more strict. At the same time, due to manual collection and processing, the scale of its industrial level is not high and the price is relatively expensive. In addition, natural wood is prone to mildew and is not suitable for outdoor use in hot and humid environments. Use, the follow-up "painting" anti-corrosion treatment also causes environmental pollution. The all-plastic material avoids the above-mentioned shortcomings, and its advantages are water resistance and corrosion resistance, mass production, and moderate pr...
