Abstract

The invention discloses a polyethylene wholly plastic wood-imitating material and a preparation method thereof. The polyethylene wholly plastic wood-imitating material comprises the following components by mass: 27%-55% of polyethylene, 8%-15% of carbon fiber, 15%-20% of crop straw powder, 5%-10% of an elastomer, 6%-10% of a flame retardant, 6%-9% of a plasticizer, 1%-3% of a crosslinking agent, 0.5%-2% of a light stabilizer, 0.5%-1% of an emulsifier, 0.1%-0.5% of an antioxidant, 0.5%-1% of an opening agent and 0.5%-2% of color. The beneficial effect is that the polyethylene wholly plastic wood-imitating material has excellent mechanical properties and good flame retardant performance, is good in heat resistance, excellent in anti aging property, low in cost, simple in production process, and can substitute wood to be used in building ornament decoration and wood furniture and other field.

Description

A kind of polyethylene full plastic imitated wood material and preparation method thereof

Technical field

The present invention relates to chemical science field, specifically a kind of polyethylene full plastic imitated wood material and preparation method thereof.

Background technology

Because timber has lightweight, beautiful texture, is easy to mechanical workout, and belong to the features such as renewable resources, dark liking by people, will one of material of most widespread use to be become in building decoration and wood furniture; On the other hand, due to exceedingly utilization, deforest and reclamation, only cut and do not make, the forest reserves are made to suffer serious broken ring, some places are destroyed by vegetation, severe water and soil erosion etc., thus in order to the offspring that benefits future generations, the whole world starts to forbid cutting down timber, and therefore wood source has become a great problem of material of construction and wood furniture.For this reason, a kind of popular material is used to replace log material to become the new direction of each producer and colleges and universities, scientific research institutions' research and development, so all kinds of imitative timber also occurs thereupon, and some is progressively widely applied, but the defect that the imitative timber on market still exists quality and produces, require further improvement, to promote quality and expansive approach field etc. better.
