Abstract

The invention discloses a PE wood / plastic composite sectional material and relates to the technical field of composite materials. The PE wood / plastic composite sectional material is made from the following raw materials in parts by weight: 10-70 parts of wood flour, 20-50 parts of polyethylene, 3-20 parts of calcium carbonate powder or talc powder, 0.1-1 part of stearic acid or n-butyl stearate, 0.4-1.5 parts of one or a combination of more than one of calcium stearate, lead stearate, barium stearate, cadmium stearate, lanthanum stearate, zinc stearate, PE wax, or oxidized polyethylene wax OPE or 0.1-1.5 parts of paraffin, 0.5-3 parts of a coupling agent, 0.5-2 parts of an antioxidant, 0.05-2 parts of a UV absorbent, a light shielding agent, quencher or free radical scavenger, and 3-12 parts of titanium pigment. The PE wood / plastic composite sectional material provided by the invention has the advantages of water resistance, insect resistance, rust corrosion resistance, convenience for fabrication, safety in use, strong plasticity, energy conservation, environmental friendliness and no formaldehyde, benzene or other poisonous substances.

Description

technical field [0001] The invention relates to the technical field of composite material profiles, in particular to a PE wood-plastic composite material profile. Background technique [0002] PE wood-plastic composite material is a composite profile made of wood fiber and PE plastic as the main material, and some polymer materials are added through special processing technology. It has a wide range of applications, including construction engineering decoration, family Decoration, wall decoration, floor, flower box, gazebo, gallery frame, seat, tray, packaging, garden landscape and many other fields. [0003] The existing manufacturing method of PE wood-plastic composite profiles is to mix and plasticize the raw materials of wood-plastic composite materials into a melt and semi-melt state, and then put them into a mold with upper and lower parts (the mold consists of an upper half and a lower half). In the mold groove of the lower half of the mold, under the action of the h...
