Embodiment 1

[0010] Embodiment 1 provides a special wood-plastic material for extruded boards instead of solid wood boards, which is composed of the following weight ratios: recycled polypropylene material: 20-45%, crop straw powder: 51-70%; lubricant: 0.2- 2.0%; coating agent: 3-15%; coupling agent: 1.0-8.0%; moisture absorbent: 1.0-5.0%; anti-aging agent: 0.5-2.0%; other additives: 0.1-5.5%.

[0011] First, weigh the recycled polypropylene material, crop straw powder, lubricant, coating agent, coupling agent, moisture absorbent, anti-aging agent, and other additives according to the proportion and mix them in the mixer at low speed for 5 minutes. The mixer adopts Low-speed mixing, the gap between the mixing blade and the cylinder wall should be less than 0.5 cm, the mixing effect of raw and auxiliary materials should be visually observed that the various particles and powders are basically uniform, and there is no obvious agglomeration or aggregation; the twin-screw extruder uses a length...

Abstract

The invention discloses a wood-plastic material replacing a solid wood plate. The wood-plastic material consists of the following components in percentage by weight: 20-45% of polypropylene reworked material, 51-70% of crop straw powder, 0.2-2.0% of lubricant, 3-15% of cladding agent, 1.0-8.0% of coupling agent, 1.0-5.0% of moisture absorbent, 0.5-2.0% of anti-aging agent and 0.1-5.5% of other auxiliaries. The extrusion plate special wood-plastic material replacing a solid wood plate disclosed by the invention solves the problems of material processability and material strength; the material can be applied to the extrusion production of various high-strength plates; the product has a beautiful appearance much like the wood appearance as well as the natural smell of wood, and the strength is much higher than that of a common solid wood plate; meanwhile, the wood-plastic material can be cut at will according to the woodwork requirements without the problems of deformation caused by water soaking and the like; and the service life is remarkably prolonged, and the cost is low.

Description

technical field [0001] The present invention relates to a composite material, and more specifically relates to a wood-plastic material that replaces solid wood boards. The invention also relates to a method for making the wood-plastic material replacing solid wood boards. Background technique [0002] With the development of social production level, people's life is more and more exquisite, and the amount of wood used in architectural decoration and furniture is increasing; at the same time, people's awareness of environmental protection and tree protection is also getting stronger; but these two This requirement seems to be a contradiction in terms. Wood-plastic materials can effectively solve the above problems. [0003] However, most of the wood-plastic materials currently on the market are made of log wood powder or wood fiber combined with plastic, which has a certain role in promoting logging and deforestation, and due to the poor strength and processability of the m...
